Sustainable Development Goals' health-related indicators for Brazil and Ecuador: an analysis for the period of 1990-2019

OBJECTIVE

This article aims to analyse the evolution of 40 Sustainable Development Goals' (SDGs) health-related indicators in Brazil and Ecuador from 1990 to 2019.

STUDY DESIGN

Epidemiological study of long-term trends in 40 SDGs' health-related indicators for Brazil and Ecuador from 1990 to 2019, using estimates from the Global Burden of Disease Study.

METHODS

Forty SDGs' health-related indicators and an index from 1990 to 2017 for Brazil and Ecuador, and their projections up to 2030 were extracted from the Institute for Health Metrics and Evaluation's Global Burden of Disease website and analysed. The percent annual change (PC) between 1990 and 2019 was calculated for both countries.

RESULTS

Both countries have made progress on child stunting (Brazil: PC = -38%; Ecuador: PC = -43%) and child wasting prevalences (Brazil: PC = -42%; Ecuador: PC = -41%), percent of vaccine coverage (Brazil: PC = +215%; Ecuador: PC = +175%), under-5 (Brazil: PC = -75%; Ecuador: PC = -60%) and neonatal mortality rates (Brazil: PC = -69%; Ecuador: PC = -51%), health worker density per 1000 population (Brazil: PC = +153%; Ecuador: PC = +175%), reduction of neglected diseases prevalences (Brazil: PC = -40%; Ecuador: PC = -58%), tuberculosis (Brazil: PC = -27%; Ecuador: PC = -55%) and malaria incidences (Brazil: PC = -97%; Ecuador: PC = -100%), water, sanitation and hygiene mortality rates (Brazil and Ecuador: PC = -89%). However, both countries did not show sufficient improvement in maternal mortality ratio to meet SDGs targets (Brazil: PC = -37%; Ecuador: PC = -40%). Worsening of indicators were found for violence, such as non-intimate partner violence for both countries (Brazil: PC = +26%; Ecuador: PC = +18%) and suicide mortality rate for Ecuador (PC = +66%), child overweight indicator for Brazil (PC = -67%), disaster mortality rates (Brazil: PC = +100%; Ecuador: PC = +325%) and alcohol consumption (Brazil: PC = +46%; Ecuador: PC = +35%).

CONCLUSIONS

Significant improvements are necessary in both countries requiring the strengthening of health and other policies, particularly concerning the prevention and management of violence and alcohol consumption, and preparedness for dealing with environmental disasters.

One Health Education Nexus: enhancing synergy among science-, school-, and teacher education beyond academic silos

Introduction

The fact that the daily lives of billions of people were affected by the medical, social, and political aspects of the SARS-CoV-2 pandemic shows the need to anchor the understanding of One Health in society. Hence, promoting awareness and deepening the understanding of the interrelation between human health, animal health, and ecosystems must be accomplished through quality education, as advocated by UN Sustainable Development Goal 4. The often-questioned and discussed measures taken by governments to control the global pandemic between 2020 and 2023 can be seen as an opportunity to meet the educational needs of civil society solutions in multi-stakeholder settings between public, universities, and schools.

Methods

This paper focuses on the integration of One Health principles in educational frameworks, particularly within the context of the higher education teaching framework "Teaching Clinic." This master-level course in the domain of pre-service teacher education serves as a potent vehicle for facilitating One Health Education, bridging the gap between research, higher education, and schools. Through the presentation of two case studies, this article demonstrates how the Teaching Clinic approach fosters interdisciplinary perspectives and provides a dynamic learning environment for pre-service teachers, as well as for pupils involved in the educational process.

Results

In both cases, the integration of educational One Health school teaching-learning settings effectively enhanced pupils' understanding of complex topics and engaged them in active learning experiences. Pre-service teachers played a crucial role in developing, implementing, and evaluating these interventions. In Case I, pupils demonstrated proficiency in analyzing data and evaluating mathematical models, while in Case II, the chosen instructional approach facilitated One Health knowledge acquisition and enjoyment among pupils. These results underscore the potential of the One Health Teaching Clinic as a valuable educational framework for enhancing teaching and learning outcomes for pre-service teachers and fostering pupil engagement in socio-scientific One Health-related topics.

Discussion

The discussion delves into the significance of breaking down disciplinary silos and the crucial role of teacher education in promoting a holistic approach to education, emphasizing the intersectionality of One Health Education and Education for Sustainable Development. This article underpins the significance of collaborative efforts across multiple (scientific) disciplines and across secondary and tertiary education levels to reach a nexus. Moreover, it emphasizes the alignment of this approach with the 2030 Agenda, Education for Sustainable Development, and Sustainable Development Goals, highlighting the potential for collective action toward a more sustainable future.

Closing the Loop: Enhancing Local Monitoring of Child Poverty to Leave No Child Behind

Research on the Leave No One Behind principle of the Sustainable Development Goals (SDGs) within the context of the Agenda 2030 is currently prevalent; however, research on monitoring child poverty at the sub-national (local) level is still limited. This paper addresses this gap by examining indicators developed for monitoring the phenomenon at different territorial levels (global, European, and national) and assessing their territorial transposition locally, using the city of Cadiz, Spain, as a case study. Interviews with local stakeholders reveal that despite the availability and access to related indicators and data, relevant actors must enhance their efforts to utilize such indicators effectively. Based on desktop research and qualitative analysis, the paper delivers recommendations for improving local monitoring of child poverty in Europe and inducing policy changes. This knowledge can inform targeted interventions, policy formulation, and resource allocation to tackle child poverty and promote equitable and inclusive societies.

Integrating the United Nations sustainable development goals into higher education globally: a scoping review

BACKGROUND

In 2015, the United Nations adopted the 2030 Agenda for Sustainable Development, including the 17 Sustainable Development Goals (SDGs). Higher education institutions have a role in raising awareness and building skills among future professionals for implementing the SDGs. This review describes how the SDGs have been integrated into higher education globally.

OBJECTIVES

Determine how have the SDGs been integrated into higher education globally. Describe the differences in the integration of the SDGs in higher education across high-income countries (HICs) and low- and middle-income countries (LMICs).

METHODS

Following a scoping review methodology, we searched Medline, Web of Science, Global Health, and Educational Resources Information Center, as well as websites of key institutions including universities, identifying peer-reviewed articles and grey literature published between September 2015 and December 2021.

RESULTS

We identified 20 articles and 38 grey literature sources. Since 2018, the number of publications about the topic has been increasing. The SDGs were most frequently included in bachelor-level education and disciplines such as engineering and technology; humanities and social sciences; business, administration, and economics. Methods of integrating the SDGs into higher education included workshops, courses, lectures, and other means. Workshops and courses were the most frequent. The methods of integration varied in high-income countries compared to low- and middle-income countries. High-income countries seemed to follow a more academic approach to the SDGs while low- and middle-income countries integrate the SDGs with the aim to solve real-world problems.

CONCLUSION

This study provides examples of progress in integrating the SDGs into higher education. Such progress has been skewed to high-income countries, bachelor-level initiatives, and certain disciplines. To advance the integration of the SDGs, lessons learned from universities globally should be shared broadly, equitable partnerships formed, and students engaged, while simultaneously increasing funding for these processes.

Plastics today: Key challenges and EU strategies towards carbon neutrality: A review

Never as today the need for collaborative interactions between industry, the scientific community, NGOs, policy makers and citizens has become crucial for the development of shared political choices and protection of the environment, for the safeguard of future generations. The complex socio-economic and environmental interconnections that underlie the EU strategy of the last years, within the framework of the Agenda 2030 and the green deal, often create perplexity and confusion that make difficult to outline the definition of a common path to achieve carbon neutrality and "net zero emissions" by 2050. Scope of this work is to give a general overview of EU policies, directives, regulations, and laws concerning polymers and plastic manufacturing, aiming to reduce plastic pollution, allowing for a better understanding of the implications that environmental concern and protection may generate from a social-economical point of view.

Life design facing the fertility gap: promoting gender equity to give women and men the freedom of a mindful life planning

Nowadays, society is characterized by enormous and rapid changes, erratic careers, gender discrimination, injustices, and inequities. Discrimination includes professional and educational segregation, the gender pay gap, stereotypical gender roles, and social expectations. In this context, phenomena called low fertility and fertility gap are increasing. Indeed, the birth rate necessary to ensure the replacement of the population is not reached, with severe repercussions at a social, environmental, and economic level. This study aimed to investigate 835 women's perceptions of the desire for motherhood and the associated difficulties. Hierarchical multiple regression and thematic decomposition analyses first highlight a significant difference between the number of children women realistically plan and the ideal number of children they would like. Secondly, the results showed how the parenthood choice is connected to the perception of social and gender inequity. Finally, in a Life Design perspective, preventive actions will be described to support women to get back to the center of life choices, building dignified fair paths and family projects.

Additional challenges in reaching hepatitis C elimination goals in Germany due to the COVID-19 pandemic - descriptive analysis of drug prescription data from January 2018 to June 2021

Effectively treating hepatitis C viral (HCV) infections prevents sequelae and onward transmission. In Germany, HCV drug prescriptions have declined since 2015. During the COVID-19 pandemic, lockdowns impacted the access to HCV care services and HCV treatment. We assessed if the COVID-19 pandemic further decreased treatment prescriptions in Germany. We built log-linear models with monthly HCV drug prescription data from pharmacies from January 2018 - February 2020 (pre-pandemic) to calculate expected prescriptions for March 2020-June 2021 and different pandemic phases. We calculated monthly prescription trends per pandemic phase using log-linear models. Further, we scanned all data for breakpoints. We stratified all data by geographic region and clinical settings. The number of DAA prescriptions in 2020 (n = 16,496, -21%) fell below those of 2019 (n = 20,864) and 2018 (n = 24,947), continuing the declining trend from previous years. The drop in prescriptions was stronger from 2019 to 2020 (-21%) than from 2018 to 2020 (-16%). Observed prescriptions met predictions from March 2020 to June 2021, but not during the first COVID-19 wave (March 2020-May 2020). Prescriptions increased during summer 2020 (June 2020-September 2020) and fell below the pre-pandemic numbers during the following pandemic waves (October 2020 - February 2021 and March 2021 - June 2021). Breakpoints during the first wave indicate that prescriptions plummeted overall, in all clinical settings and in four of six geographic regions. Both, outpatient clinics and private practices prescribed overall as predicted. However, outpatient hospital clinics prescribed 17-39% less than predicted during the first pandemic wave. HCV treatment prescriptions declined but stayed within the lower realms of predicted counts. The strongest decline during the first pandemic wave indicates a temporary HCV treatment gap. Later, prescriptions matched predictions despite of pronounced decreases during the second and third waves. In future pandemics, clinics and private practices need to adapt more rapidly to maintain a continuous access to care. In addition, political strategies should focus more on continuously providing essential medical care during periods of restricted access due to infectious disease outbreaks. The observed decrease in HCV treatment may challenge reaching the HCV elimination goals in Germany by 2030.

Analyzing SDG interlinkages: identifying trade-offs and synergies for a responsible innovation

This paper responds to recent calls to address the indivisible nature of the Sustainable Development Goal (SDG) framework and the related knowledge gap on how SDG targets interlink with each other. It examines how SDG targets interact in the context of a specific technology, point of care (PoC) microfluidics, and how this relates to the concept of responsible innovation (RI). The novel SDG interlinkages methodology developed here involves several steps to filter the relevant interlinkages and a focus group of experts for discussing these interlinkages. The main findings indicate that several social synergies occur when deploying PoC microfluidics, but that the environmental trade-offs may jeopardize the total progress toward the SDGs. More specifically, the environmental sacrifices (use of plastics and lack of recyclability) resulted in the product being cheaper and, thus, better accessible. This work suggests that attention should be given (and prioritized) to the use of renewable and recyclable materials without jeopardizing the accessibility of the product. This should minimize the identified trade-offs. These findings inform how analyzing SDG interlinkages relates to the responsibilities and dimensions of RI in several ways. First, analyzing SDG interlinkages helps to execute the governance responsibility by using the RI dimensions (anticipation, reflexivity, inclusion and responsiveness). Second, analyzing SDG interlinkages gives insights into if and how a technology relates to the do-good and avoid-harm responsibility. This is important to assess the responsiveness of the technology to ensure that the technology can become truly sustainable and leaves no one behind.

Toward agenda 2030 in education: policies and practices for effective school leadership

School leadership has been described as a key target for leveraging the quality of education in relation to sustainable development goal (SDG4) that seeks to 'ensure inclusive and quality education for all and promote lifelong learning' as per UNESCO 2030 agenda. This study provides a policy review of school leadership in the State of Qatar, as a case study, but carries out discussions within the global thrive for meeting the demands of Agenda 2030 to achieve quality for public education. It utilized a research instrument developed by UNESCO's Division for Policies and Lifelong Learning Systems in Paris. The study used personal interview surveying, also called face-to-face surveying, and was completed with high-level policymakers at the Ministry of Education and Higher Education (MOEHE). It consisted of four sections that addressed: (1) the regulatory frameworks governing school leadership; (2) the professional development opportunities offered to school leaders; (3) the degree the school leadership profession was attractive; and (4) the procedures followed to appraise school leaders. Findings underscore the critical role played by school autonomy, instructional leadership, and governance in responding to Agenda 2030. The discussion contributes to the global discourse in meeting the requirements of Agenda 2030.

Assuming accuracy, pretending influence? Risks of measuring, monitoring and reporting sustainable development goals

From the local to global level, indicators and reports are produced and published to support the transition towards sustainable development. Building from two European-level science-policy workshops, this perspective essay discusses the types of risks involved with such sustainability reporting. The analysis is rooted in the framework of the UN 2030 Agenda and sustainable development goals (SDG). As a globally adopted framework, it provides an example of how risks are either recognised and framed, or non-recognised. Well recognised risks include data availability for SDGs and siloed preparation of indicators, while risks receiving less attention are ritualistic reporting lacking a critical evaluation of the limitations of the SDG framework itself. These different risks are likely to reinforce each other. A specific risk is a too narrow focus on one-way communication aiming to inform individual policy decisions. Risks related to SDGs are best managed with iterative, integrative and interactive knowledge production fostering holistic understanding.

Development and Evaluation of Options for Action to Progress on the SDG 6 Targets in Austria

The Agenda 2030 of the United Nations stipulates an ambitious set of 17 Sustainable Development Goals (SDGs). They were globally agreed upon and demand coherent, context-specific implementation at the national level. To address the complexity of challenges therein, the Agenda is designed to be integrated, indivisible, and universal. The numerous multifaceted interactions in-between the SDGs and with corresponding measures pose a complex challenge for decision-makers implementing them worldwide that requires support for a comprehensive discourse in the science-society-policy arena. Research on the interactions between the SDGs has been flourishing and can help to understand where policy options might be most successfully located. A catalytic effect on several other goals is, e.g., often attributed to SDG 6 on water and sanitation. However, beyond the where to locate policy options, it is similarly important to understand how potential policy options would affect the SDGs and their targets. We developed eleven options and 85 measures as context-specific pathways to advance the SDG 6 Targets in Austria. As a country in the Global North and with a generally far-established water and sanitation infrastructure and management, this responds to the Agenda's demand for universal applicability and can serve as an example to illustrate potential challenges beyond basic infrastructure provision and management. The proposed options cover resources-oriented sanitation, blue-green-brown infrastructure, efficient use and integrated management of water resources, maintenance and restoration of ecological functions of inland waters, reduction of diffuse discharge of nutrients and problematic substances as well as trace substances, water, sanitation and hygiene in public spaces, groundwater protection, development cooperation as well as co-design and co-creation. Their effects on the SDG 6 Targets are evaluated using a 7-point-scale. The evaluation method is simple and practicable, and fosters discourse on the entire water cycle amongst the expert group applying the method. The evaluated effects on the targets are found to be unanimously positive or neutral, but trade-offs might arise when including other SDGs in the assessment, making an expansion of the evaluation necessary for coherent implementation. The results can be used as a baseline to support follow-up discussions with stakeholders and decision-makers.

Sustainable development goals: a bibliometric analysis of literature reviews

The research in sustainable development goals (SDG) increases year by year since its approval in 2015. Typically, after a phase of exponential growth, the number of publications increases at lower rates, suggesting a consolidation process in which literature reviews become a relevant and high-evidence type of document. In this context, the aim of this study was to perform an unprecedented bibliometric analysis of literature reviews on SDG to assess the evolution and consolidation of the scientific research. Article reviews on SDG from 2015 to 2022 were retrieved from Web of Science core collection and a descriptive bibliometric analysis was performed by growth rate, research area, source, citation, and region. Mapping and cluster analysis using keyword co-occurrence, co-authorship, and bibliographic coupling were also applied. The result revealed that SDG is a fast-growing field, with a trend in the diversification of research areas. Most of the review documents were categorized in general aspects of sustainability. Technology (SDG 9) and economic growth (SDG 8) were spotted as hidden key research areas. This result is contrary to previous bibliometric studies on SDG, demonstrating the rapid evolution and change in the field. In addition, literature reviews on reduced inequalities (SDG 10), gender equality (SDG 5); oceans, seas, and marine environments (SDG 14); and peace, justice, and strong institutions (SDG 16) were revealed as research gaps. Thus, the results demonstrated that the research on SDG cannot yet be considered a consolidated area of research, as it leaves many SDG unexplored. Future research has been proposed accordingly.

Bioindicators for the Sustainability of Sugar Agro-Industry

The worldwide sugar industry presents a productive inertia and a fragile sustainability due to there are marginal advances in the productivity, productive diversification, and reduction of the environmental impact in cane crop fields, sugar factories, distilleries, and non-centrifuged sugar production. The complexity of sustainability evaluation in sugar industry is highlighted by the incorporation of many criteria including both quantitative and qualitative issues, measured by different units or at least the development of standards for benchmarking. The key to successful sustainability will ultimately depend on the progress in sugarcane productivity without increasing the cultivated area and decreases the environmental impacts without the lack of coordination between public policies, stakeholders, and markets which would have benefits and wellness on social, economic, and environmental aspects. The aim of this research was to carry out a review about the sustainability frameworks, indicators, constraints, and barrier to transit the sugar industry to sustainability. The results present opportunities and strengths of sugar industry related to 2030 agenda for sustainable development and circular economy as an useful guidance to formulate strategies to maximizing the potential of the sugar industry to a sustainable biofactory.

A systems model of SDG target influence on the 2030 Agenda for Sustainable Development

The Sustainable Development Goals (SDGs) were adopted by the United Nations in 2015 as part of the "2030 Agenda for Sustainable Development" and aim to address issues ranging from poverty and economic growth to climate change. Efforts to tackle one issue can support or hinder progress towards others, often with complex systemic interactions. Thus, each of the SDGs and their corresponding targets may contribute as levers or hurdles towards achieving other SDGs and targets. Based on SDG indicator data, we create a systems model considering influence among the SDGs and their targets. Once assessed within a system, we find that more SDGs and their corresponding targets act as levers towards achieving other goals and targets rather than as hurdles. In particular, efforts towards SDGs 5 (Gender Equality) and 17 (Partnerships for the Goals) may accelerate progress, while SDGs 10 (Reduced Inequalities) and 16 (Peace, Justice and Strong Institutions) are shown to create potential hurdles. The model results can be used to help promote supportive interactions and overcome hindering ones in the long term.

Fossil fuels, stranded assets and COVID-19: Imagining an inclusive & transformative recovery

The 2015 Paris Agreement on Climate Change implicitly requires phasing out fossil fuels; such a phase out may cost hundreds of trillions of dollars and induce widespread socio-ecological ramifications. The COVID-19 'pancession' (pandemic + recession) has rattled global economies, possibly accelerating the fossil fuel phase out. This raises the question: What opportunities has COVID-19 presented to phase out fossil fuels, and subsequently, how can transformative recovery efforts be designed to utilize these opportunities and promote social, ecological and relational inclusiveness? We find that: (a) the COVID-19 pancession provides a unique opportunity to accelerate climate action, as it has devalued financial assets, stunned fossil fuel production and paralyzed relevant infrastructure, thus easing the pathway towards stranding global fossil fuel resources and assets; (b) four possible post-pancession recovery scenarios may unravel, of which only one is ecologically, socially and relationally inclusive, transformative, and in line with the Paris Agreement and Agenda 2030; and (c) an inclusive recovery requires that political leadership channels the gargantuan state resources for recovery into prioritizing healthcare and the environment as public/merit goods, conscious investment in non-fossil fuel energy sector recovery accompanied by stringent climate policy, and equitably managing stranded assets to ensure that the burden falls on rich and capable actors, predominantly from the North.

Global Health in Swedish Nursing Curricula: Navigating the Desirable and the Necessary

Global health challenges are likely to be aggravated in the coming years by rapid climate change and environmental degradation. To address the resulting health inequities, nurses need an integrated understanding of environmental and social determinants of health. This study adopts an explorative inductive approach to examine how global health and sustainability are expressed the course syllabi of undergraduate nursing programmes (n = 24) in Sweden. After excluding biomedical and other unrelated content, 67 syllabi were selected for a thematic analysis. Results indicate that global health, the social determinants of health and sustainability tend to appear in a fragmented manner in the syllabi. Global health content is often limited, relegated to elective courses, or altogether missing. A theoretical framework is lacking, and focus lies on an individual rather than structural perspective. Based on international policy, earlier studies on undergraduate nursing education and theoretical work, suggestions are made for how global health and sustainability content could be integrated into nursing education, notably by using a structural competency approach.

Does green financing help to improve environmental & social responsibility? Designing SDG framework through advanced quantile modelling

Striving to achieve the Sustainable Development Goals (SDGs), countries are increasingly embracing a sustainable financing mechanism via green bond financing. Green bonds have attracted the attention of the industrial sector and policymakers, however, the impact of green bond financing on environmental and social sustainability has not been confirmed. There is no empirical evidence on how this financial product can contribute to achieving the goals set out in Agenda 2030. In this study, we empirically analyze the impact of green bond financing on environmental and social sustainability by considering the S&P 500 Global Green Bond Index and S&P 500 Environmental and Social Responsibility Index, from October 1, 2010 to 31st July 2020 using a combination of Quantile-on-Quantile Regression and Wavelet Multiscale Decomposition approaches. Our results reveal that green financing mechanisms might have gradual negative transformational impacts on environmental and social responsibility. Furthermore, we attempt to design a policy framework to address the relevant SDG objectives.

Achieving HIV targets by 2030: the possibility of using debt relief funds for sustainable HIV treatment in sub-Saharan Africa

This paper assesses the possibility of using debt relief funds to sustain HIV treatment in sub-Saharan Africa, suppress transmission, and reach global goals to quell the epidemic by 2030. The cost of providing antiretroviral treatment is a huge burden on African countries. Concerns for Africa's capacity to keep pace with global advances are well founded. By analysing levels of 'debt distress', health expenditure per capita, and HIV antiretroviral therapy requirements in sub-Saharan African countries, the need for innovative finance with international cooperation emerges clearly. In addition to the HIV epidemic, African countries may become more vulnerable to disasters and other public health diseases such as malaria, tuberculosis, Ebola and COVID-19, especially without alternatives to current means of financing. Relief from debt service payments could release funds for sub-Saharan African countries to support universal HIV antiretroviral treatment with sustainable results.

Behavioural and structural interventions in cancer prevention: towards the 2030 SDG horizon

Traditionally, the prevention of cancer (and other chronic diseases) has been considered primarily linked to personal responsibility, for which interventions must be based on health education information enabling individuals to make knowledge‐based decisions to improve their lifestyle. However, lifestyle is conditioned by environmental factors (including dimensions such as the context of economics, transport, urbanism, agriculture or education) that may render healthy behavioural choices either easier or, alternatively, impossible. This article reviews the conceptual underpinnings of the behavioural‐structural dichotomy. We believe that it is advisable to opt for multilevel strategies that take into account all the determinants of health, using structural and behavioural approaches, rather than only the latter, as has been done until now.

Sustainable and acceptable school meals through optimization analysis: an intervention study

Background

School meals hold considerable potential to shape children’s diets and reduce food-related greenhouse gas emissions (GHGE)—in the short and long term. This study applied linear optimization to develop a GHGE-reduced, nutritionally adequate, and affordable school lunch menu. The effects on food waste, consumption and pupils’ satisfaction with the meals were evaluated.

Methods

A pre-post design was employed to assess the effects of implementing an optimized lunch menu on daily food waste, consumption, and pupils’ school meal satisfaction in three schools (grades 0–9) from one Swedish municipality. A food list containing amounts, prices, nutrient content, and GHGE-values of all foods used for a previously served (baseline) four-week lunch menu was created. Using linear programming, this food list was optimized for minimum deviation and constrained to ensure nutritional adequacy and a reduced climate impact. The optimized food list was developed into a new (intervention) four-week lunch menu by a professional meal planner, following the baseline menu as closely as possible. The baseline and intervention menus were served for four weeks, respectively, with a two week break in between. Prepared, wasted and leftover food were weighed daily by the school kitchen staff during both periods. Interrupted time series analysis assessed mean and slope differences in daily food waste and consumption between the two periods. School lunch satisfaction was assessed with an online questionnaire at baseline and during the intervention.

Results

Optimization resulted in a food list that was 40% lower in GHGE, met all nutrient recommendations for school meals, and cost 11% less compared to baseline. The intervention menu was served as planned, with only minor changes required (for practical reasons). Plate waste, serving waste, consumption and school lunch satisfaction did not differ significantly from baseline, in any of the schools.

Conclusions

The findings demonstrate that school meals can successfully be improved regarding health and environmental sustainability using linear optimization, without negative effects on food waste, consumption or cost. This approach offers the necessary flexibility to tailor menus towards different priorities and could therefore be transferred to other types of meal services.

Trial registration

The trial is registered at clinicaltrials.gov (NCT04168632 Fostering Healthy and Sustainable Diets Through School Meals (OPTIMAT).

Optimizing School Food Supply: Integrating Environmental, Health, Economic, and Cultural Dimensions of Diet Sustainability with Linear Programming

There is great potential for reducing greenhouse gas emissions (GHGE) from public-sector meals. This paper aimed to develop a strategy for reducing GHGE in the Swedish school food supply while ensuring nutritional adequacy, affordability, and cultural acceptability. Amounts, prices and GHGE-values for all foods and drinks supplied to three schools over one year were gathered. The amounts were optimized by linear programming. Four nutritionally adequate models were developed: Model 1 minimized GHGE while constraining the relative deviation (RD) from the observed food supply, Model 2 minimized total RD while imposing stepwise GHGE reductions, Model 3 additionally constrained RD for individual foods to an upper and lower limit, and Model 4 further controlled how pair-wise ratios of 15 food groups could deviate. Models 1 and 2 reduced GHGE by up to 95% but omitted entire food categories or increased the supply of some individual foods by more than 800% and were deemed unfeasible. Model 3 reduced GHGE by up to 60%, excluded no foods, avoided high RDs of individual foods, but resulted in large changes in food-group ratios. Model 4 limited the changes in food-group ratios but resulted in a higher number of foods deviating from the observed supply and limited the potential of reducing GHGE in one school to 20%. Cost was reduced in almost all solutions. An omnivorous, nutritionally adequate, and affordable school food supply with considerably lower GHGE is achievable with moderate changes to the observed food supply; i.e., with Models 3 and 4. Trade-offs will always have to be made between achieving GHGE reductions and preserving similarity to the current supply.

Multi actor multi criteria analysis (MAMCA) as a tool to build indicators and localize sustainable development goal 11 in Brazilian municipalities

The Sustainable Development Goals (SDGs) were adopted in 2015 to be a guideline to promote sustainable development through partnerships. Goal 11 was designed to improve the quality of life in cities however, confronted local governments with new challenges to delivery services and increase citizen participation. In this study, a conceptual framework was developed, and distinct indicators were analyzed to facilitate the implementation of SDG 11 in Brazilian municipalities. Two case studies were deployed based on the Multi-Actor Multi-Criteria Analysis (MAMCA) to guarantee stakeholder participation during the whole process. The results brought to light important challenges to urbanization at local levels. Also, the results suggest shifts in the ongoing model to evaluate the implementation of SDG 11 in Brazil. Governance, transparency and social participation were identified as critical issues to be addressed. Moreover, it will be necessary to adjust existing indicators and organize a consistent and frequent method to evaluate progress towards achieving SDG 11 targets at local levels. Integration of plans and policies related to climate change and disaster risk reduction represents another challenge to be faced by local governments. Finally, MAMCA can be a helpful tool to support local decision-makers to implement SDG 11 based on a multi-stakeholder view.

Policy coherence to achieve the SDGs: using integrated simulation models to assess effective policies

Coherently addressing the 17 Sustainable Development Goals requires planning tools that guide policy makers. Given the integrative nature of the SDGs, we believe that integrative modelling techniques are especially useful for this purpose. In this paper, we present and demonstrate the use of the new System Dynamics based iSDG family of models. We use a national model for Tanzania to analyse impacts of substantial investments in photovoltaic capacity. Our focus is on the impacts on three SDGs: SDG 3 on healthy lives and well-being, SDG 4 on education, and SDG 7 on energy. In our simulations, the investments in photovoltaics positively affect life expectancy, years of schooling and access to electricity. More importantly, the progress on these dimensions synergizes and leads to broader system-wide impacts. While this one national example illustrates the anticipated impact of an intervention in one specific area on several SDGs, the iSDG model can be used to support similar analyses for policies related to all the 17 SDGs, both individually and concurrently. We believe that integrated models such as the iSDG model can bring interlinks to the forefront and facilitate a shift to a discussion on development grounded in systems thinking.
