Family farming in climate change: Strategies for resilient and sustainable food systems

Family farming plays a pivotal role in ensuring household food security and bolstering the resilience of food systems against climate change. Traditional agricultural practices are evolving into context-specific, climate-resilient systems such as family farming, homestead gardening, and urban agriculture. This study examines the ways in which family farming can foster climate-resilient food systems amidst climate vulnerabilities. A systematic literature review spanning the past 22 years was undertaken to develop a conceptual framework. From this review, 37 pertinent documents were identified, leading to the creation of a context-specific, climate-resilient food system framework. The research posits that family farming facilitates easy access to food and nutrition by capitalizing on family-sourced land, labor, and capital, and by securing access to technology and markets. Each facet of family farming is intricately linked with sustainability principles. Local adaptation strategies employed by climate-vulnerable households can diminish their vulnerability and augment their adaptive, absorptive, and transformative capacities, enabling them to establish a climate-resilient food system. The research further reveals that farming families employ a myriad of strategies to fortify their food systems. These include crop diversification, adjusting planting times, cultivating high-value crops and fish, planting fruit trees, rearing poultry and livestock, and leveraging their land, labor, and resources-including their homesteads-to access food and nutrition. This study endorses the climate-resilient family farming framework and offers multiple metrics for assessing the resilience of family farming in developing countries.

Conservation Agriculture Impacts on Economic Profitability and Environmental Performance of Agroecosystems

The rationale of this study originates from the primary sector's multiple roles in the global warming issue. Agriculture is reported among the main causes of anthropogenic global warming. At the same time, it is profoundly impacted by climate change and concurrently holds potential as a solution through the sequestration of soil organic carbon (SOC) facilitated by Conservation Agriculture (CA). However, the findings in the literature are controversial on the SOC sequestration capacity and the profitability of CA implementation. Considering the new and old objectives of the sector, this paper tackles the assessment of the actual capabilities of CA to be a viable strategy to pursue the social good of climate change mitigation and concurrently be profitable for farmers. The economic profitability and environmental performance of CA are assessed analysing data from a field experiment in Northern Italy (European temperate area) and identifying the best management practice by means of a data envelopment analysis.

Expert opinion survey on Israel's food system: implications for food and health policies

BACKGROUND

While there has been increasing global recognition and impetus for action to transform food systems towards greater food security, sustainability and better health outcomes, Israel has only recently begun to focus on the diverse challenges of its food system and its potential for transformation.

METHODS

An expert opinion survey (n = 50) on Israel's food system was conducted as part of a larger study on the systemic features of Israel's food system transition to understand its policy gaps and find strategies towards a healthy and sustainable food system. The survey ranks the relevance and importance of food system challenges and policy preferences. Policy implications are then examined by identifying potential priorities, gaps and dissensus.

RESULTS

The survey finds that there is a majority agreement (76%) that Israel's food policies are lacking or severely lacking. Respondents relate strongly to both concepts of nutritional security (90% think that access to nutritious food is relevant or highly relevant) and national food security (more than 80% perceive food security as part of national security). Respondents overwhelmingly recognize the benefits of Israeli agriculture with 60-90% agreeing or strongly agreeing that it benefits food security, economic value and national identity. Top-ranked problems include overall systemic problems such as the lack of national goals, strategic planning, and integrated policymaking across ministries, and specific ones such as food waste, costly farming inputs, and food affordability. The most preferred policy actions include establishing a national strategy for food and agriculture, making food affordable for vulnerable households, and incentivising sustainable farming methods. The key policy gaps include the lack of resilience in agriculture and the food system, insufficient data and knowledge for policy action, inadequate attention to the regulation of the food industry for better health and inadequate food policy attention for minority groups.

CONCLUSIONS

Building on this study's findings, further policy research and implementation areas to be covered include government responsibility for universal food security, strategic systemic policies for food systems, prevention and preparedness for future crises, and promoting resilience. The way forward may best be through an inter-ministerial committee with the responsibility, budgets, mandate and executive authority to plan data-driven policies for a sustainable food system for Israel's future.

A review on food subsystem simulation models for the water-food-energy nexus: development perspective

Agricultural crops are the primary food source because livestock and poultry products also indirectly depend on crops. A significant obstacle to adopting the water, food, and energy (WFE) nexus is the lack of a comprehensive and easy-to-use simulation model for the food subsystem focusing on crops. By reviewing the articles in Scopus and Google Scholar databases, WFE nexus studies can be divided into two categories: simulation-based and conceptual-based studies of WFE nexus. Based on the developmental perspective on food subsystem modeling in the WFE nexus, the conceptual studies were excluded, and the modeling studies were reviewed. Two points of view can be used for WFE nexus modeling: 1. hard-link modeling and 2. soft-link modeling. Comparing these two types of modeling showed that hard-link modeling cannot model the interrelations of the food subsystem, and this shortcoming is of great importance. This study reviewed the crop growth models (CGMs) used in the WFE nexus system from the development perspective. The technical characteristics of the CGMs have been evaluated according to the requirements of the CGMs. Finally, a checklist based on the criteria defined for the nexus system has been provided, which can guide researchers in choosing the appropriate CGMs for the food subsystem with the nexus approach. The analysis revealed that none of the CGMs studied alone were sufficient to develop a simulation model for the food subsystem with the WFE nexus. However, the AquaCrop model met more criteria.

Food fraud and mitigating strategies of UK food supply chain during COVID-19

Covid-19 had shown the vulnerability of the food supply chain and fraudsters may take advantage of the pandemic whilst the population needed a continuous supply of safe and quality food. The lack of monitoring and policing in the food supply chain may encourage fraudsters to upscale their operations. Previous studies had warned of a surge in fraudulent products due to COVID-19. This raised the question on whether food fraud had increased during the pandemic? This study aims to investigate food fraud during COVID-19 and how the food supply chain develops mitigating strategies against fraudulent activities. A mixed-method approach including survey and semi-structured interviews were conducted among UK food businesses. Two hundred and two agri-food businesses responded to the survey and 15 semi-structured interviews were conducted. The majority of the food businesses did not experience an increase of food fraud activities during COVID-19. Two thematic domains and ten sub-themes were identified from the data set. There was a heightened sense of anticipation and preparation for increased fraudulent activities during the pandemic. The main risk mitigating strategies included horizon scanning; developing and maintaining supplier relationship and assurance; understanding product characteristics, testing capabilities, conducting vulnerability assessments and training. Practical and cost-effective strategies for small and medium food businesses were recommended. This is the first empirical study on food fraud and mitigating strategies of the UK food supply chain during the pandemic. Our findings provide evidence for informing the policies and practices of the food regulatory authorities as well as best practices to protect the UK food supply chain against food fraud during exogenous shocks like COVID-19.

Implications of US agricultural data practices for sustainable food systems research

Using the tenets of data feminism, we analyse the National Agricultural Statistics Service Quick Stats database - the primary repository of United States agricultural data. We identify unstated assumptions built into the database's scaffolding through data collection, aggregation and dissemination practices, revealing how they facilitate granular analyses of agricultural topics historically judged as national priorities while leaving unilluminated many others of vital importance for contemporary sustainability needs. We argue that this entrenches an inequitable and unsustainable food systems status quo, and we offer recommendations for data providers and users based on principles of reflexivity, context and pluralism.

Un-yielding: Evidence for the agriculture transformation we need

There has been a seismic shift in the center of gravity of scientific writing and thinking about agriculture over the past decades, from a prevailing focus on maximizing yields toward a goal of balancing trade-offs and ensuring the delivery of multiple ecosystem services. Maximizing crop yields often results in a system where most benefits accrue to very few (in the form of profits), alongside irreparable environmental harm to agricultural ecosystems, landscapes, and people. Here, we present evidence that an un-yielding, which we define as de-emphasizing the importance of yields alone, is necessary to achieve the goal of a more Food secure, Agrobiodiverse, Regenerative, Equitable and just (FARE) agriculture. Focusing on yields places the emphasis on one particular outcome of agriculture, which is only an intermediate means to the true endpoint of human well-being. Using yields as a placeholder for this outcome ignores the many other benefits of agriculture that people also care about, like health, livelihoods, and a sense of place. Shifting the emphasis to these multiple benefits rather than merely yields, and to their equitable delivery to all people, we find clear scientific evidence of win-wins for people and nature through four strategies that foster FARE agriculture: reduced disturbance, systems reintegration, diversity, and justice (in the form of securing rights to land and other resources). Through a broad review of the current state of agriculture, desired futures, and the possible pathways to reach them, we argue that while trade-offs between some ecosystem services in agriculture are unavoidable, the same need not be true of the end benefits we desire from them.

Strengthening agroecological resilience through commons-based seed governance in the Philippines

The Filipino agricultural sector is exposed to multiple climatic, economic, and social risks that will likely intensify in the near future. Building agroecological resilience has been proposed to protect small-scale farmers' livelihoods and improve food security in the context of (unexpected) shocks and disruptions, and slow system changes such as climate change. This paper argues that commons-based seed production, based on collective management and ownership of seeds and varieties, can play a central role in building resilience capacities in smallholder communities. I explore this by applying an indicator-based framework to assess the contribution of the Filipino farmer network Magsasaka at Siyentipiko para sa Pag-unlad ng Agrikultura (MASIPAG) to agroecological resilience. I find that the networks' commons-based seed governance builds agroecological resilience in various ways. By equipping small-scale farmers with the tools to regain control over seed production and breeding, they become stewards of an actively evolving collection of varieties. The in situ maintenance and development of traditional, open-pollinated varieties and a network of diversified trial and backup farms build up buffering capacities and foster agrobiodiversity and local adaptation. A focus on regionally available natural resources reduces vulnerabilities to external factors. Adaptive capacities are strengthened through a high degree of flexibility and responsiveness achieved by self-organization and polycentric organizational structures. Broad participation, shared learning and spaces for experimentation support the development of farmers' capacities to respond to diverse challenges. Commons-based approaches to seed governance can thus strengthen agroecological resilience and long-term food security in smallholder agricultural systems.

Does Crop Diversity Influence Household Food Security and Women's Individual Dietary Diversity? A Cross-Sectional Study of Malawian Farmers in a Participatory Agroecology and Nutrition Project

BACKGROUND

Agroecological methods have the potential to impact nutrition and food security, however, to date there is limited research evaluating this approach.

OBJECTIVE

A 5-year participatory research project with farming households in north and central Malawi was designed to train farmers on agroecological practices, alongside raising awareness on nutrition and gender equity. This cross-sectional study aimed to explore the relationships between crop diversity, food security at the household level, and individual diversity for women, within the context of an agroecology, nutrition education, and farmer mentoring program.

METHODS

Participating farmers were trained in and experimented with different farming methods. These farmers subsequently trained other farmers on these short-term agroecological practices and provided mentorship using community-based educational methods designed to address both household food security and nutrition. In year 4 of the intervention, a cross-sectional survey assessed farm practices, food security, and individual dietary diversity of 851 participating households.

RESULTS

Households with lower crop diversity were significantly less likely to be food secure (odds ratios [OR] = 0.829, P < .001). Women in households with higher crop diversity were more likely to have higher individual dietary diversity (OR = 1.120, P < .01), eat vitamin A rich foods (OR = 1.176, P < .01), and legumes, nuts, and seeds (OR = 1.141, P < .01).

CONCLUSIONS

These findings suggest that within a participatory agroecological training combined with community-based nutrition education with a focus on social equity, crop diversity is associated with less household food insecurity and poorer diet quality for rural farming households. Crop diversity may improve dietary diversity by making nutritious foods more available.

Toward Better Food Security Using Concepts from Industry 5.0

The rapid growth of the world population has increased the food demand as well as the need for assurance of food quality, safety, and sustainability. However, food security can easily be compromised by not only natural hazards but also changes in food preferences, political conflicts, and food frauds. In order to contribute to building a more sustainable food system-digitally visible and processes measurable-within this review, we summarized currently available evidence for various information and communication technologies (ICTs) that can be utilized to support collaborative actions, prevent fraudulent activities, and remotely perform real-time monitoring, which has become essential, especially during the COVID-19 pandemic. The Internet of Everything, 6G, blockchain, artificial intelligence, and digital twin are gaining significant attention in recent years in anticipation of leveraging the creativity of human experts in collaboration with efficient, intelligent, and accurate machines, but with limited consideration in the food supply chain. Therefore, this paper provided a thorough review of the food system by showing how various ICT tools can help sense and quantify the food system and highlighting the key enhancements that Industry 5.0 technologies can bring. The vulnerability of the food system can be effectively mitigated with the utilization of various ICTs depending on not only the nature and severity of crisis but also the specificity of the food supply chain. There are numerous ways of implementing these technologies, and they are continuously evolving.

The use of wheatgrass (<i>Thinopyrum intermedium</i>) in breeding

Wheatgrass (Th. intermedium) has been traditionally used in wheat breeding for obtaining wheat-wheatgrass hybrids and varieties with introgressions of new genes for economically valuable traits. However, in the 1980s in the United States wheatgrass was selected from among perennial plant species as having promise for domestication and the development of dual-purpose varieties for grain (as an alternative to perennial wheat) and hay. The result of this work was the creation of the wheatgrass varieties Kernza (The Land Institute, Kansas) and MN-Clearwater (University of Minnesota, Minnesota). In Omsk State Agrarian University, the variety Sova was developed by mass selection of the most winter-hardy biotypes with their subsequent combination from the population of wheatgrass obtained from The Land Institute. The average grain yield of the variety Sova is 9.2 dt/ha, green mass is 210.0 dt/ ha, and hay is 71.0 dt/ha. Wheatgrass is a crop with a large production potential, benef icial environmental properties, and valuable grain for functional food. Many publications show the advantages of growing the Kernza variety compared to annual crops in reducing groundwater nitrate contamination, increasing soil carbon sequestration, and reducing energy and economic costs. However, breeding programs for domestication of perennial crops are very limited in Russia. This paper presents an overview of main tasks faced by breeders, aimed at enhancing the yield and cultivating wheatgrass eff iciency as a perennial grain and fodder crop. To address them, both traditional and modern biotechnological and molecular cytogenetic approaches are used. The most important task is to transfer target genes of Th. intermedium to modern wheat varieties and decrease the level of chromatin carrying undesirable genes of the wild relative. The f irst consensus map of wheatgrass containing 10,029 markers was obtained, which is important for searching for genes and their introgressions to the wheat genome. The results of research on the nutritional and technological properties of wheatgrass grain for the development of food products as well as the differences in the quality of wheatgrass grain and wheat grain are presented.

Consumer-driven strategies towards a resilient and sustainable food system following the COVID-19 pandemic in Australia

Background

The COVID-19 pandemic and associated public health restrictions temporarily disrupted food supply chains around the world and changed the way people shopped for food, highlighting issues with food systems resilience and sustainability. The aim of this study was to explore consumer-driven strategies towards a more resilient and sustainable food system in Australia, learning from experiences during the beginning of the COVID-19 pandemic.

Methods

During May–June 2020, a cross-sectional, online survey was conducted in Tasmania, Australia in a non-random sample of adults aged 18 years and over. The survey collected demographic data and posted the open-ended question: “How could Tasmania’s food system be better prepared for a disaster in the future?” Descriptive statistics were used to analyse the demographic data and thematic analysis was employed to analyse the qualitative data.

Results

Survey respondents (n = 698) were predominantly female (79%), over 55 years of age (48%), university educated (70%) and living with dependents (45%). Seven key themes were identified: (i) balance food exports with local needs; (ii) strengthen local food systems; (iii) increase consumer awareness of food supply chains; (iv) build collaboration and connection in the food system; (v) embed clear contingency arrangements; (vi) support community capacity building and individual self-sufficiency; and (vii) the food system coped well.

Conclusions

The consumer-driven strategies identified indicate multiple opportunities to increase resilience and sustainability in the food system to avoid future supply disruptions. Our findings indicate that considerable popular support for more resilient, local and sustainable food systems may be emerging from the COVID-19 pandemic.

Impacts of the Russia-Ukraine War on Global Food Security: Towards More Sustainable and Resilient Food Systems?

As a conflict between two major agricultural powers, the Russia–Ukraine war has various negative socioeconomic impacts that are now being felt internationally and might worsen, notably, for global food security. If the war deepens, the food crisis will worsen, posing a challenge to many countries, especially those that rely on food imports, such as those in the Middle East and North Africa (MENA) region. Simultaneously, the war came at a bad time for global food markets because food prices were already high due to disruptions in the supply chain caused by the COVID-19 pandemic, strong global demand, and poor harvests in some countries. Understanding how conflict-related disruptions in global food and fertilizer markets might affect price and availability is critical for understanding the overall impact on global food security. Further, four months into the war, its implications for food security suggest that this review is timely, urgent, and highly needed. Accordingly, this paper aims to investigate the Russia–Ukraine war’s direct and indirect impact on global food security. The paper highlights that the war resulted in immediate and far-reaching cascading consequences on global food security: Ukrainian exports have stopped, conscription and population displacement have caused labor shortages, access to fertilizers is restricted, and future harvests are uncertain. First, Ukraine’s export capacity has been hampered. Secondly, conscription and population displacement caused labor shortages. Thirdly, access to vital agricultural products such as fertilizers is also constrained. The war may delay spring planting and winter crop harvesting. Further, the war has indirect and cascading effects. Indeed, rising fertilizer costs may reduce their use and crop yields. Moreover, as seen during the 2007–2008 food crisis, export restrictions and speculation are driving up international prices and worsening the situation. Furthermore, the war triggered a panic buying movement at country and individual levels. Finally, the war may jeopardize the implementation of the Sustainable Development Goals (SDGs), notably SDG 1 (No poverty), SDG 2 (Zero hunger), and DG 12 (Responsible consumption and production). However, the consequences of the war on food security are being exacerbated by a variety of underlying rigidities, vulnerabilities, and inefficiencies in global food systems. Accordingly, the transition toward healthy, equitable, and ecologically sustainable food systems must be strengthened by adopting urgent and long-term reforms and policies.

Degrowth in Practice: Developing an Ecological Habitus within Permaculture Entrepreneurship

The literature on degrowth has suffered from only engaging with normative ideas. More recently the degrowth debate has started moving from a normative perspective to close the wide gap that has existed between normative ideas and is analysing how to link ideas to the institutional and cultural environment that shapes practices. To address this challenge, we draw on the work of Pierre Bourdieu in order to examine transformations in the habitus and forms of capital of those who decide to move into sustainable entrepreneurship through permaculture in Brazil. Permaculture represents a vibrant alternative to industrial food production and addresses fundamental contemporary social problems, such as increasing inequalities, climate change and the loss of biodiversity. The article explores the challenges faced and respective responses of those who decide to change their relationships with nature and society by becoming permaculture entrepreneurs (PEs). The paper shows that, when entering the permaculture universe, individuals start critically examining their values and ways of living, which leads to a disengagement from dominant patterns of behaviour and social expectations in order to pursue sustainable lifestyles and thereby develop an ecological habitus.

A qualitative assessment of gender roles in child nutrition in Central Malawi

Background

Child malnutrition persists globally with men and women playing distinct roles to support children’s nutrition. Women frequently carry the bulk of the workload related to food, care, and health, all of which are critical factors in child nutrition. For this reason, development efforts have emphasised women ignoring the potential role of men in supporting children’s nutrition. This study sought to understand the different roles that Malawian men and women play in children’s nutrition.

Methods

This qualitative was conducted in rural Central Malawi as part of a baseline study in 2017 for the CARE Southern Africa Nutrition Initiative. Seventy-six participants were interviewed, including 19 men and 57 women, using focus group discussions and in-depth interviews. We sought to understand the gender distribution of men’s and women’s roles and how these roles influence child nutrition.

Results

We found that both men and women were involved in productive, reproductive, and community work. However, consistent with the literature, women carried a disproportionate workload in supporting child nutrition compared to men. Women’s heavier workloads often prevented them from being able to meet children’s food needs. Nevertheless, shifts in gender roles were observed in some of the sampled communities, with men taking up responsibilities that have been typically associated with women. These changes in gender roles, however, did not necessarily increase women’s power within the household.

Conclusions

Traditional gender roles remain prevalent in the sampled communities. Women continue to be primarily responsible for the food, care, and health of the household. Women’s heavy workloads prevent them from providing optimal care and nutrition for children. While efforts to advance gender equality by encouraging men to participate in child care and other household responsibilities appear to have had marginal success, the extent to which these efforts have successfully encouraged men to share power remains unclear. Improving gender equality and child nutrition will require efforts to redistribute gendered work and encourage men to move towards shared power with women over household decision-making and control over income.

Food Flows and the Roles of Cities in West African Food Distribution Networks

In West Africa, rampant urbanization is changing food systems, including the magnitude and composition of food flows and the length of supply chains. An increasing body of literature discusses pathways to sustainable transformation of urban food systems taking into account links between urban and rural spaces. Research and policy have focused on the role of cities as consumption centers receiving food from local, regional, and global hinterlands. This study aims at widening the perspective on the role of cities in food distribution, by bringing into focus a city's function as a consumption, aggregation, and disaggregation center. The analysis is based on a comprehensive set of primary data on food flows collected in four West African cities across different seasons. The analysis shows that the investigated cities are integrated into multi-scale urban and market networks. Their position within these networks interacts with their reliance on other territories for food supply and with their functions, such as the aggregation of goods. The capital cities of Ouagadougou (Burkina Faso) and Bamako (Mali) relied more on lower-rank urban settlements further away, while Tamale, a secondary city in Ghana, acted as an assembly market for local rural producers and in turn supplied larger urban centers. Bamenda, a secondary city in Cameroon, acted as a consumption center sourcing mainly from its hinterland. Beyond that, city functions were context-specific and varied according to type of product and season. Extending the perspective on the role of cities has implications for policy, including bringing into focus and strengthening midstream segments, such as market and transport links.

The COVID-19 pandemic reveals an unprecedented rise in hunger: The South African Government was ill-prepared to meet the challenge

Recent research has shown increasing household food and nutrition insecurity in South Africa, indicating weaknesses in the national food system due to historical and current socioeconomic inequalities. The lack of inclusive governance and collaboration among actors and institutions to develop long-term strategies increase the problem. Such weaknesses intensify the government's ill-preparedness to provide food relief during disasters. We drew upon two rounds of the longitudinal University of Johannesburg and the Human Sciences Research Council's COVID-19 Democracy Survey to illustrate how ill-preparedness has resulted in increased hunger. The rollout of food relief was slow because the state ignored established non-governmental food relief structures. Delayed tender processes and corruption have worsened local distribution and access to food relief, increasing households' hunger. Individuals reported higher experiences of hunger above pre-COVID-19 figures of 11% attaining highs of 42% in 2020. We argue that COVID-19 has emphasised the South African food system's inequalities, particularly the state's inability to ensure integration, inclusiveness and rapidly provide emergency food relief. We focused on individual and households’ experiences of hunger and economic circumstances. Challenges were evident where access to food was provided in-kind or through financial aid. The pandemic food relief interventions and the lack of food price controls were serious challenges. The state and stakeholders must prevent high transitory food insecurity levels from resulting in chronic food insecurity. The state's practices and challenges during lockdown must be examined to ensure this situation does not reoccur. Some essential foods require subsidisation and price regulation to ensure long-term access for the poor. To ensure zero hunger and increased food security, these elements of the NDP must be re-examined. Research is required on vulnerabilities in the system, ways to overcome these and the understanding of factors contributing to system-wide resilience, including at individual and household levels.

Scanning Models of Food Systems Resilience in the Indo-Pacific Region

The Indo-Pacific is a region of the world experiencing rapid growth in population and development. However, it is also exposed to a number of social, economic, geopolitical, and biophysical stressors, which may undermine the region's ability to support its population, ensure food security, and sustain livelihoods. In response to the complex suite of stressors, a number of development initiatives and research programs have been established to build resilience in the region's food systems. These initiatives vary in scope and scale, but also in what they mean by the term resilience and the components of the food system they address. This variation has implications for the outcomes of these efforts and how well they match a theoretical ideal of resilience. This review examines how resilience and food systems are defined, conceptualized, and applied within research studies and projects or initiatives on food systems resilience funded or supported by national, regional, or multilateral government, and non-governmental institutions in the Indo-Pacific region. It also compares how the concepts are treated from an academic or theoretical perspective vs. in practical applications. We take a two-pronged approach: first, identifying organizations engaged in the Indo-Pacific region and developing an inventory of initiatives and projects that have bearing on food systems resilience; and second, carrying out literature searches to record research studies in the region that examine resilience within food systems. We then identify any formalized frameworks or definitions of resilience and/or food systems guiding these projects and studies. The results indicate there is a heavy focus on climate change and natural disasters, and to a lesser extent health-related shocks, in food systems resilience research and practice. Definitions, however, are inconsistently reported, and are often more simplistic than resilience theory depicts, favoring resilience conceptualizations around adaptation and a production-oriented food systems framing. While the specific definitions vary between research and applied projects, the fragmented and ambiguous use of terms presents a challenge for policy applications and coordination. Overall, establishing some clear guiding resilience principles, modified according to contextual factors, could enable more streamlined resilience work in Indo-Pacific food systems.

Shared Logistic Service for Resilient Agri-Food System: Study of E-Commerce for Local and B2B Markets in Japan

Escalating intensification and homogenization occurring throughout the supply chain poses serious challenges to the global food supply. Several approaches have been developed to shift the food systems to a more resilient path; however, the high unit costs of shipping impede its development. This paper proposes a shared logistic service supported by E-commerce as a solution to this problem. It analyzes the shared logistic system developed by Vegibus Ins. in Japan which has unique features, such as fixed routes. It argues that the logistic service has the ability to connect different scales while supporting flexible transactions leading to the construction of a resilient agri-food system. At the same time, the paper points out the need for subsidies from the governments to facilitate this kind of shared logistic service at the initial stage as one limitation to this approach.

Diverse adaptation strategies helped local food producers cope with initial challenges of the Covid-19 pandemic: Lessons from Québec, Canada

The Covid-19 pandemic has demonstrated the vulnerability of food systems to disturbances. Advocates have promoted short food supply chains as more resilient and adaptable thanks to their embeddedness in local economic and ecological networks. As part of a broader case study on challenges facing farmers in local food supply chains in Québec, Canada, we asked farmers about the pandemic's impacts on food production and marketing in the province, including how food producers coped with these challenges. We sent an online questionnaire to 1,046 farmers who distribute food through direct marketing in Québec, identified through consumer-facing online platforms. We conducted follow-up interviews with 15 of the 133 farmers that completed the questionnaire to gain a better understanding of their pandemic-related challenges and opportunities, as well as their adaptation needs and strategies. We identified four main types of challenges among farmers: workforce shortages, balancing food demand and supply, changes in sales outlets and marketing channels, and other operational and development issues. In turn, six key adaptation strategies helped farmers reorganize their marketing and sales, which we categorize as: redistribution, streamlining, replacement, collaboration, farm adjustment, and outlet adjustment. Most surveyed local farmers felt well-prepared to adapt to the four major challenges that the Covid-19 pandemic forged or escalated, and our findings suggest that they demonstrated remarkable resilience to additional challenges posed by the pandemic. Our study therefore contributes important insights about how flexibility and redundancy among local farmers stabilized the local food system during the onset of a global pandemic.

Community Supported Agriculture, Human Capital, and Community Health

Community supported agriculture (CSA) strengthens the local food system (LFS) and plays a critical role in promoting human capital (HC) and addressing social determinants of health (SDH). Most CSAs develop relationships that build a sense of community, and engage in activities that facilitate access to food and economic opportunities. CSAs may also contribute to personal development, education and income, working experience, and knowledge. CSA principles align with the principles of HC, specifically the pursuit of economic development. While research on the connection between CSA and HC has broadly focused on the economic aspect, the human development dimension has remained at the conceptual level. The purpose of this study was to assess the potential HC contributions by CSA and the implications for health outcomes in central/northern New Mexico. Primary and secondary data were collected through a semi-structured, open-ended questionnaire and an internet search. Purposive sampling was used to select 13 CSAs. Eight (61.5%) responded and reported activities that address HC and SDH such as training, job creation, education, access to healthy food, food security, health education and disease management, social connections, and food justice. Given the potential impact, public health must contribute to CSA by generating evidence on its health and social benefits, training practitioners on supporting local food program, and promoting policy that stimulates the local economy, fosters social relations and food justice, and empowers community members. This study calls for research and practice to take a multilevel perspective on the contribution of LFSs to equity and wellbeing.

Reducing Tillage Affects Long-Term Yields but Not Grain Quality of Maize, Soybeans, Oats, and Wheat Produced in Three Contrasting Farming Systems

Reducing tillage has been widely promoted to reduce soil erosion, maintain soil health, and sustain long-term food production. The effects of reducing tillage on crop nutritional quality in organic and conventional systems, however, has not been widely explored. One possible driver of crop nutritional quality might be the changing soil nitrogen (N) availability associated with reduced tillage in various management systems. To test how reducing tillage affects crop nutritional quality under contrasting conventional and organic farming systems with varied N inputs, we measured nutritional quality (protein, fat, starch, ash, net energy, total digestible nutrients, and concentrations of Ca, K, Mg, P, and S) of maize, wheat, oats, and soybeans harvested from a long-term trial comprised of three farming systems under two tillage regimes: a conventional grain system (CNV); a low-input organic grain system (LEG); and an organic, manure-based grain + forage system (MNR) under conventional full-tillage (FT) and reduced-till (RT) management. Although maize and wheat yields were 10–13% lower under RT management, grain quality metrics including protein, fat, starch, energy, and mineral concentrations were not significantly affected by reducing tillage. Differences in nutrient quality were more marked between farming systems: protein levels in maize were highest in the MNR system (8.1%); protein levels in soybeans were highest in the LEG system (40.4%); levels of protein (12.9%), ash (2.0%), and sulfur (1430 ppm) in wheat were highest in the CNV system, and oat quality was largely consistent between the LEG and MNR systems. As grain quality did not significantly respond to reducing tillage, other management decisions that affect nutrient availability appear to have a greater effect on nutrient quality.

Public Policies for Agricultural Diversification: Implications for Gender Equity

Gender equity is recognized as central to sustainable development, but women still face significant constraints in accessing and controlling productive resources important for agricultural livelihoods. Identifying mechanisms (e.g., policies and interventions) in agriculture that enhance women's empowerment—a critical aspect of gender equity—is of paramount importance for sustainable development. In this study, we investigate how Brazil's flagship targeted public food procurement program, the National School Feeding Program (PNAE), influences women's empowerment in southern Brazil. We conducted household surveys on farm characteristics and practices, women's empowerment (e.g., participation in farm decision-making and control over income), and women's participation in social movements, with farmers (n = 75) who do and do not participate in the PNAE. We found that women were more empowered in households participating in the PNAE, and that this empowerment was associated with diversified farming systems. When women had greater levels of participation in farm management decisions, agrobiodiversity and use of agroecological practices were higher. We also show that women's participation in agroecological social movements was associated with significantly higher empowerment (both in control over income and greater participation in decision-making). This study identifies targeted public food procurement as a promising policy instrument with potential to link cross-sectoral Sustainable Development Goals (SDGs) to sustainably increase food production (SDG 2), provide economic opportunities for small-scale farmers (SDG 1), and create an economic space that women in agriculture can more easily access (SDG 5).

Women's dual centrality in food security solutions: The need for a stronger gender lens in food systems' transformation

Food insecurity remains a critical issue worldwide. The current COVID-19 crisis has exposed how vulnerable the global food systems are and that urgent measures need to be taken, especially in the Global South. Despite increased recognition that women are among the most food insecure yet major contributors to local and global food security over the recent years, there has not been a systemic change needed in the current food security paradigm. This paper argues that, in developing countries, a stronger gender lens ought to be at the center to the food systems' debate as women are critical to agriculture and food systems' sustainability and resilience. Women are central to food systems, both as primary food producers and as primary caretakers of the household. Three key recommendations are put forward in this article for establishing inclusive, sustainable and resilient food systems: One, ensuring a stronger gender lens in food systems and food security paradigms; by working with accurate sex-disaggregated data and beyond on individuals' level. Two, promoting and supporting alternative strategies to agriculture as a means of livelihood for women. Three, ensuring that women are central in food security solutions by not only listening to their concerns and needs, but also building on their resilience, knowledge, and practices.

Toward Zero Hunger Through Coupled Ecological Sanitation-Agriculture Systems

Ecological sanitation (EcoSan) systems capture and sanitize human excreta and generate organic nutrient resources that can support more sustainable nutrient management in agricultural ecosystems. An emerging EcoSan system that is implemented in Haiti and several other contexts globally couples container-based household toilets with aerobic, thermophilic composting. This closed loop sanitation system generates organic nutrient resources that can be used as part of an ecological approach to soil nutrient management and thus has the potential to contribute to Sustainable Development Goals 2 (zero hunger), 6 (clean water and sanitation for all), and 13 (climate change solutions). However, the role of organic nutrient resources derived from human excreta in food production is poorly studied. We conducted a greenhouse experiment comparing the impact of feces-derived compost on crop production, soil nutrient cycling, and nutrient losses with two amendments produced from wastewater treatment (pelletized biosolids and biofertilizer), urea, and an unfertilized control. Excreta-derived amendments increased crop yields 2.5 times more than urea, but had differing carry-over effects. After a one-time application of compost, crop production remained elevated throughout all six crop cycles. In contrast, the carry-over of crop response lasted two and four crop cycles for biosolids and biofertilizer, respectively, and was absent for urea. Soil carbon concentration in the compost amended soils increased linearly through time from 2.0 to 2.5%, an effect not seen with other treatments. Soil nitrous oxide emissions factors ranged from 0.3% (compost) to 4.6% (biosolids), while nitrogen leaching losses were lowest for biosolids and highest for urea. These results indicate that excreta-derived compost provides plant available nutrients, while improving soil health through the addition of soil organic carbon. It also improved biogeochemical functions, indicating the potential of excreta-derived compost to close nutrient loops if implemented at larger scales. If captured and safely treated through EcoSan, human feces produced in Haiti can meet up to 13, 22, and 11% of major crop needs of nitrogen, phosphorus, and potassium, respectively.

Response-to-Failure Analysis of Global Food System Initiatives: A Resilience Perspective

International food system initiatives have led the efforts to combat the threats to global food security resulting from the failure of the current food systems. This study set out to investigate and assess the contributions of global food system initiatives in tackling the food system challenges. In assessing the food system initiatives, we develop a three-step methodology for Food System Initiative (FSI) selection and then conduct a qualitative evaluation using relevant indicators based on food system failure narratives. Furthermore, the authors synthesize present literature in the context of the extent to which coronavirus disease 2019 (COVID-19) pandemic has compounded food system challenges and, together with the response-to-failure analysis, recreate a resilient transformational framework, which will be an invaluable tool to FSI during and after the COVID-19 era, and guarantee we build back better. The findings show that while considerable effort is being made in addressing food system failures, the current COVID-19 pandemic has exacerbated the challenges and would require a paradigm shift not only in the implementation of conventional food system initiatives but also in the role of food system actors. The food system resilience framework presented provides useful pathway in expanding the understanding of the role of all key stakeholders and in identifying tipping points for building the desired resilience moving forward.

A Multifunctional Solution for Wicked Problems: Value-Chain Wide Facilitation of Legumes Cultivated at Bioregional Scales Is Necessary to Address the Climate-Biodiversity-Nutrition Nexus

Well-managed legume-based food systems are uniquely positioned to curtail the existential challenge posed by climate change through the significant contribution that legumes can make toward limiting Green House Gas (GHG) emissions. This potential is enabled by the specific functional attributes offered only by legumes, which deliver multiple co-benefits through improved ecosystem functions, including reduced farmland biodiversity loss, and better human-health and -nutrition provisioning. These three critical societal challenges are referred to collectively here as the “climate-biodiversity-nutrition nexus.” Despite the unparalleled potential of the provisions offered by legumes, this diverse crop group remains characterized as underutilized throughout Europe, and in many regions world-wide. This commentary highlights that integrated, diverse, legume-based, regenerative agricultural practices should be allied with more-concerted action on ex-farm gate factors at appropriate bioregional scales. Also, that this can be achieved whilst optimizing production, safeguarding food-security, and minimizing additional land-use requirements. To help avoid forfeiting the benefits of legume cultivation for system function, a specific and practical methodological and decision-aid framework is offered. This is based upon the identification and management of sustainable-development indicators for legume-based value chains, to help manage the key facilitative capacities and dependencies. Solving the wicked problems of the climate-biodiversity-nutrition nexus demands complex solutions and multiple benefits and this legume-focus must be allied with more-concerted policy action, including improved facilitation of the catalytic provisions provided by collaborative capacity builders—to ensure that the knowledge networks are established, that there is unhindered information flow, and that new transformative value-chain capacities and business models are established.

Food insecurity related to agricultural practices and household characteristics in rural communities of northeast Madagascar

Ending hunger and alleviating poverty are key goals for a sustainable future. Food security is a constant challenge for agrarian communities in low-income countries, especially in Madagascar. We investigated agricultural practices, household characteristics, and food security in northeast Madagascar. We tested whether agricultural practices, demographics, and socioeconomics in rural populations were related to food security. Over 70% of respondents reported times during the last three years during which food for the household was insufficient, and the most frequently reported cause was small land size (57%). The probability of food insecurity decreased with increasing vanilla yield, rice yield, and land size. There was an interaction effect between land size and household size; larger families with smaller land holdings had higher food insecurity, while larger families with larger land had lower food insecurity. Other socioeconomic and agricultural variables were not significantly related to food insecurity, including material wealth, education, crop diversity, and livestock ownership. Our results highlight the high levels of food insecurity in these communities and point to interventions that would alleviate food stress. In particular, because current crop and livestock diversity were low, agricultural diversification could improve outputs and mitigate food insecurity. Development of sustainable agricultural intensification, including improving rice and vanilla cultivation to raise yields on small land areas, would likely have positive impacts on food security and alleviating poverty. Increasing market access and off-farm income, as well as improving policies related to land tenure could also play valuable roles in mitigating challenges in food security.

Multi-Species Genomics-Enabled Selection for Improving Agroecosystems Across Space and Time

Plant breeding has been central to global increases in crop yields. Breeding deserves praise for helping to establish better food security, but also shares the responsibility of unintended consequences. Much work has been done describing alternative agricultural systems that seek to alleviate these externalities, however, breeding methods and breeding programs have largely not focused on these systems. Here we explore breeding and selection strategies that better align with these more diverse spatial and temporal agricultural systems.

Seafood businesses' resilience can benefit from circular economy principles

Seafood is expected to become increasingly important in future food systems and healthy diets. This transition will require the seafood sector to adapt business practices to respond to environmental and social challenges while increasing resilience. Here, we develop the circular economy-resilience framework for business models (CERF-BM) and, through exploring the current literature, apply this framework to business models in the seafood sector. We find that the majority of business models incorporate elements of circular economy and resilience in a limited way. The reviewed business models often fail to consider other supply chain actors and, instead, focus on the business itself and its customers. The CERF-BM helps to elucidate this disconnect through assessing business models against company-level actions towards circularity in combination with systems-level resilience mechanisms. To reap the synergies between the circular economy and resilience mechanisms, seafood businesses could extract more value from organic waste and dematerialize their business models.

Academy of Nutrition and Dietetics: Revised 2020 Standards of Professional Performance for Registered Dietitian Nutritionists (Competent, Proficient, and Expert) in Sustainable, Resilient, and Healthy Food and Water Systems

Current systems of food production and consumption are challenged by factors such as natural resource constraints, relative unaffordability of nutrient-dense foods, persistent social inequities, and high rates of diet-related disease. Registered dietitian nutritionists (RDNs) play a critical role in protecting the health of current and future populations by advancing sustainable, resilient, and healthy food and water systems. By definition, such systems can meet current dietary needs without jeopardizing the ability to meet the needs of future generations; can withstand or adapt to disturbances over time; and can equitably facilitate disease prevention and well-being for all individuals. This area of practice within nutrition and dietetics requires recognition of the complex interrelationships among indiviudal health and economic, environmental, and social domains of food and nutrition, and allows RDNs to bring unique expertise to diverse interprofessional teams. The Revised 2020 Standards of Professional Performance for RDNs (Competent, Proficient, and Expert) in Sustainable, Resilient, and Healthy Food and Water Systems update the 2014 standards and cover the following 6 standards of professional performance: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements that illustrate how the RDN can apply the principles of sustainable food systems to a variety of practice settings. The indicators describe 3 skill levels (ie, competent, proficient, and expert) for RDNs in this focus area.

Social-ecological analysis of timely rice planting in Eastern India

Timely crop planting is a foundation for climate-resilient rice-wheat systems of the Eastern Gangetic Plains-a global food insecurity and poverty hotspot. We hypothesize that the capacity of individual farmers to plant on time varies considerably, shaped by multifaceted enabling factors and constraints that are poorly understood. To address this knowledge gap, two complementary datasets were used to characterize drivers and decision processes that govern the timing of rice planting in this region. The first dataset was a large agricultural management survey (rice-wheat: n = 15,245; of which rice: n = 7597) from a broad geographic region that was analyzed by machine learning methods. The second dataset was a discussion-based survey (n = 112) from a more limited geography that we analyzed with graph theory tools to elicit nuanced information on planting decisions. By combining insights from these methods, we show for the first time that differences in rice planting times are primarily shaped by ecosystem and climate factors while social factors play a prominent secondary role. Monsoon onset, surface and groundwater availability, and land type determine village-scale mean planting times whereas, for resource-constrained farmers who tend to plant later ceteris paribus, planting is further influenced by access to farm machinery, seed, fertilizer, and labor. Also, a critical threshold for economically efficient pumping appears at a groundwater depth of around 4.5 m; below this depth, farmers do not irrigate and delay planting. Without collective action to spread risk through synchronous timely planting, ecosystem factors such as threats posed by pests and wild animals may further deter early planting by individual farmers. Accordingly, we propose a three-pronged strategy that combines targeted strengthening of agricultural input chains, agroadvisory development, and coordinated rice planting and wildlife conservation to support climate-resilient agricultural development in the Eastern Gangetic Plains.

Defining and validating regenerative farm systems using a composite of ranked agricultural practices

Background: Ongoing efforts attempt to define farms as regenerative to aid marketers, policymakers, farmers, etc. The approach needs to balance precision with function, and must be transparent, simple, scalable, transferable, incorruptible, and replicable. Methods: We developed practice-based scoring systems to distinguish regenerative cropland and rangeland, and validate them based on whether these scores scaled with regenerative goals on actual farm operations. Study systems included cornfields of the Upper Midwest, almond orchards of California, and rangeland systems of the Northern Plains. Response variables included soil carbon and organic matter, soil micronutrients, water infiltration rates, soil microbial communities, plant community structure, invertebrate community structure, pest populations, yields, and profit. Results: Regenerative outcomes were strongly correlated with our approach to farm scoring. Soil organic matter, fine particulate organic matter, total soil carbon, total soil nitrogen, phosphorous, calcium and sulfur all increased alongside regenerative matrix scores in one or both of the cropping systems. Water infiltration rates were significantly faster in more regenerative almond orchards. Soil bacterial biomass and Haney soil health test scores were higher as cropland incorporated more regenerative practices. Plant species diversity and biomass increased significantly with the number of regenerative practices employed on almonds and rangelands. Invertebrate species diversity and richness were positively associated with regenerative practices in corn, almonds, and rangelands, whereas pest populations and almond yields were unaffected by the number of regenerative practices. Corn yields were negatively associated with more regenerative practices, while almond yields were unaffected by the number of regenerative practices. Profit was significantly higher on more regenerative corn and almond operations. Conclusions: Our scoring system scaled positively with desired regenerative outcomes, and provides the basis for predicting ecosystem responses with minimal information about the farming operation. Natural clusters in the number of regenerative practices used can be used to distinguish regenerative and conventional operations.

Aquaculture-capture fisheries nexus under Covid-19: impacts, diversity, and social-ecological resilience

The Covid-19 pandemic is a global shock that is significantly affecting coastal social-ecological systems (SES) in different parts of the world. Its widespread impacts have unravelled vulnerabilities in many aspects of society, including food systems. Our study investigated the impacts of a lockdown associated with the pandemic in the province of Bulacan, in the region of Central Luzon, Philippines, where aquaculture and capture fisheries are important and interconnected sectors. In particular, we focused on impacts related to production and market. We considered people's coping strategies and the factors that enabled such strategies. Our investigation adopted a case study approach and drew on qualitative data analysed through thematic analysis. The findings revealed differentiated mechanisms through which aquaculture and capture fisheries production were impacted. Both were strongly affected by market disruptions but through slightly different ways. In effect, the lockdown provided the impetus for the uptake and spreading of practices that were previously peripheral, particularly in relation to market exchanges. The study also identified a variety of coping strategies, as well as the importance of social support in the form of food aid, financial assistance, and institutional livelihood assistance. Finally, it discusses the importance of diversity in food sources, the role of local food systems, and governance implications for foregrounding social-ecological resilience in short-term response and long-term recovery.

An agent based model representation to assess resilience and efficiency of food supply chains

Trying to meet the Sustainable Development Goals is challenging. Food supply chains may have to become more efficient to meet the increasing food requirement of 10 Billion people by 2050. At the same time, food and nutrition security are at risk from increasingly likely shocks like extreme climate events, market shocks, pandemics, changing consumer preferences, and price volatility. Here we consider some possibilities and limitations regarding the improvement of resilience (the capacity to deal with shocks) and efficiency (here interpreted as the share of produced food delivered to consumers) of food supply chains. We employ an Agent Based Model of a generic food chain network consisting of stylized individuals representing producers, traders, and consumers. We do this: 1/ to describe the dynamically changing disaggregated flows of crop items between these agents, and 2/ to be able to explicitly consider agent behaviour. The agents have implicit personal objectives for trading. We quantify resilience and efficiency by linking these to the fraction of fulfilment of the overall explicit objective to have all consumers meet their food requirement. We consider different types of network structures in combination with different agent interaction types under different types of stylized shocks. We find that generally the network structures with higher efficiency are also more sensitive to shocks, while less efficient network types display more resilience. At first glance these results seem to confirm the existence of a system-level trade-off between resilience and efficiency similar to what is reported in business management and ecology literature. However, the results are modified by the trading interactions and the type of shock. In our simulations resilience and efficiency are affected by ‘soft’ boundaries caused by the preference and trust of agents (i.e., social aspects) in trading. The ability of agents to switch between trading partners represents an important aspect of resilience, namely a capacity to reorganize. These insights may be relevant when considering the reorganization of real-life food chains to increase their resilience to meet future food and nutrition security goals.

The role of reducing food waste for resilient food systems

Food waste undermines long-term resilience of the global food system by aggravating ecosystem damage. The global community must therefore work to reduce the amount of food that gets wasted. However, we should be mindful of some potential conflicts between food waste reduction and food system resilience. Over-production and over-supply are a contributing cause of waste, yet they also provide resilience in the form of redundancy. In this paper, we examine individual interventions designed to minimise food waste by scoring their impact on different aspects of resilience. We find that there are strong synergistic elements and interventions that support short- and long-term resilience, such as improved storage, which reduces the need to provide a constant flow of 'surplus food' and replaces it with a stock of 'spare' food. Some interventions carry a risk of trade-offs due to possible losses of redundancy, and investment lock-in that may reduce the ability of farmers to adapt by changing what and where they farm. Trade-offs do not mean that those interventions should not be pursuit, but they should be recognised so that can be adequately addressed with complimentary actions. This review underlines the necessity of food-systems thinking and joined-up policy.

Revealing soil legacy phosphorus to promote sustainable agriculture in Brazil

Exploiting native soil phosphorus (P) and the large reservoirs of residual P accumulated over decades of cultivation, namely "legacy P", has great potential to overcome the high demand of P fertilisers in Brazilian cropping systems. Long-term field experiments have shown that a large proportion (> 70%) of the surplus P added via fertilisers remains in the soil, mainly in forms not readily available to crops. An important issue is if the amount of legacy P mobilized from soil is sufficient for the crop nutritional demand and over how long this stored soil P can be effectively 'mined' by crops in a profitable way. Here we mapped the spatial-temporal distribution of legacy P over the past 50 years, and discussed possible agricultural practices that could increase soil legacy P usage by plants in Brazil. Mineral fertiliser and manure applications have resulted in ~ 33.4 Tg of legacy P accumulated in the agricultural soils from 1967 to 2016, with a current annual surplus rate of 1.6 Tg. Following this same rate, soil legacy P may reach up to 106.5 Tg by 2050. Agricultural management practices to enhance soil legacy P usage by crops includes increasing soil pH by liming, crop rotation, double-cropping, inter-season cover crops, no-tillage system and use of modern fertilisers, in addition to more efficient crop varieties and inoculation with P solubilising microorganisms. The adoption of these practices could increase the use efficiency of P, substantially reducing the new input of fertilisers and thus save up to 31.8 Tg of P fertiliser use (US$ 20.8 billion) in the coming decades. Therefore, exploring soil legacy P is imperative to reduce the demand for mineral fertilisers while promoting long-term P sustainability in Brazil.

Who is resilient in Africa's Green Revolution? Sustainable intensification and Climate Smart Agriculture in Rwanda

Under the banner of a "New Green Revolution for Africa," agricultural intensification programs aim to make smallholder agriculture more productive as well as "climate smart". As with Green Revolutions in Asia and Mexico, agricultural innovations (hybrid seeds, agronomic engineering, market linkages,and increased use of fertilizer and pesticides) are promoted as essential catalysts of agriculture-led economic growth. Intensification programs are now frequently linked to Climate Smart Agriculture (CSA), which attempts to build resilience and reduce greenhouse gas emissions while increasing crop yields. This article considers who and what is resilient in Africa's Green Revolution. We report on a multi-season study of smallholder food producers' experiences with Rwanda's Crop Intensification Program (CIP) and related policies that aim to commercialize subsistence agriculture while implementing CSA. . We suggest that there are fundamental limits to the climate resilience afforded by CSA and development efforts rooted in Green Revolution thinking. Our findings illustrate that such efforts foreground technology and management adjustments in ways that have reduced smallholder resilience by inhibiting sovereignty over land use, decreasing livelihood flexibility, and constricting resource access. We put forth that rural development policies could better promote climate-resilient livelihoods through: 1) adaptive governance that enables smallholder land use decision-making; 2) support for smallholder food producers' existing agro-ecological strategies of intensification; 3) participatory approaches to visualize and correct for inequalities in local processes of social-ecological resilence Such considerations are paramount for meeting the United Nations Sustainable Development Goals and building climate-resilient food systems.

Sustainability transitions in the context of pandemic: an introduction to the focused issue on social innovation and systemic impact

For society to achieve the Sustainable Development Goals, the agri-food industry needs a substantial sustainability transition toward food systems capable of delivering greater volumes of nutritious food, while simultaneously lowering the environmental footprint. This issue of AHV focuses on the big picture-on mechanisms of sustainability transition, from social innovation, to models of finance and institutional systems, and calls for business and agricultural researchers to transform the sector together. Contributors to this issue embrace a transdisciplinary outlook, including scientific, technical, social and political dimensions of agroecology. This issue is a call to action: to encourage the community of social entrepreneurs, ecosystem players and researchers to contribute analytical methods, experiences and scientific insights on emerging social innovations related to food, agriculture and rural-urban transformation.
