Enhancing science-policy interfaces for food systems transformation

EU-27 ecological footprint was primarily driven by food consumption and exceeded regional biocapacity from 2004 to 2014

The European Union (EU) plans to decarbonize the region by 2050. As highlighted by the Green Deal and Farm to Fork Strategy, food systems are essential for this transition. Here we investigate the resource dependence and carbon emissions of the EU-27's food systems from 2004 to 2014 via an ecological footprint (EF)-extended multi-regional input-output approach, accounting for demand and supply (including trade), and considering multiple externalities. Food contributes towards almost a third of the region's EF, and appropriates over half of its biocapacity. Average reliance on biocapacity within national borders decreased, while reliance on intra-EU biocapacity increased; yet a quarter of the biocapacity for food consumption originates from non-EU countries. Despite a reduction in both total EF and food EF over the study period, EU-27 residents demand more from nature than the region's ecosystems can regenerate-highlighting the need for new or strengthened food and trade policies to enable a transformation to sustainable EU food systems.

An approach to conflicts of interest in UK food regulatory institutions

The history of food is replete with examples of food scandals leading to institutional and procedural reforms intended to rebuild trust. For trust to be sustainable, systems need to be trustworthy. Food regulatory institutions are at the interface of science and policy, and they should have robust and reliable mechanisms for identifying and addressing commercial conflicts of interest (COIs) among the membership of their boards and advisory committees. Here we provide a detailed estimate, analysis and critique of COIs within the United Kingdom's food regulatory institutions. This exercise was facilitated by the United Kingdom's rule requiring declarations of COIs, which are published. Institutions that require and publish declarations of COIs are probably more trustworthy than those that do not, while institutions that exclude all individuals with COIs could be even more trustworthy.

Spatial Differences of Nutrient Adequacy in Coastal Areas of China

Ensuring nutrient adequacy for all is a common goal of the international community, but spatial difference is one of the barriers to its development. Exploring nutrient adequacy in coastal areas of China can help regions where food production systems and economic development systems are under mutual stress to reduce nutritional disparities and improve nutrition levels. This paper used the transformation food-to-nutrient model to calculate nutrient production and nutrient consumption in 11 coastal provinces of China and analyzed their spatial patterns, after which spatial differences in nutrient adequacy (including energy, protein and fat) were analyzed. The results showed that nutrient production and nutrient consumption in coastal areas of China showed significant spatial differences, in which nutrient production was mainly concentrated in land food, and the three provinces of Shandong, Jiangsu and Hebei contributed more. Guangdong had the highest nutrient consumption; in contrast, Shanghai, Tianjin, and Hainan had the lowest consumption. Nutrient adequacy was not optimistic, with fat being particularly significant, and nutrient surplus quantity was mainly concentrated in Shandong and Jiangsu and nutrient deficiency quantity was mainly concentrated in Guangdong. Overall, the study area had adequate levels of protein and was deficient in energy and fat levels, with surplus or shortage of 2.41 million tonnes, 2620 billion kcal and 9.97 million tonnes, respectively.

Planning for sustainable food communities: An optimal spatial allocation study of food hubs considering the 15-min city concept—The case of LebensMittelPunkte in Berlin

Food hubs (FHs) providing neighbourhoods with regional food from agroecological production are a promising concept for a sustainable food system transformation. However, their operationalization and scaling are still unclear. We developed a methodological approach that, for the first time, scales out FHs to an entire city (Berlin) based on a 15-min walking distance and socio-culturally oriented sub-districts as underlying spatial units. We considered the population density and the distance to organic groceries, public transportation and between FHs to estimate their most suitable locations. The results reveal an optimal allocation of 231 FHs covering 91% of the city's populated areas in a radius lower than 1 km and almost the entire city within a 1.5 km radius. We found this approach to be a meaningful way to plan the inner-city allocation of FHs from an integrative perspective and to adopt urban policies by considering the local specificities of each neighbourhood. The scaling out of agroecology-based regional FHs in Berlin allows for the creation of a sustainable city-region food system that increases the resilience of the metropolitan food environment. We generally propose a participative and integrative approach in order to realise this process.

The triple benefits of slimming and greening the Chinese food system

The Chinese food system has undergone a transition of unprecedented speed, leading to complex interactions with China's economy, health and environment. Structural changes experienced by the country over the past few decades have boosted economic development but have worsened the mismatch between food supply and demand, deteriorated the environment, driven obesity and overnutrition levels up, and increased the risk for pathogen spread. Here we propose a strategy for slimming and greening the Chinese food system towards sustainability targets. This strategy takes into account the interlinkages between agricultural production and food consumption across the food system, going beyond agriculture-focused perspectives. We call for a food-system approach with integrated analysis of potential triple benefits for the economy, health and the environment, as well as multisector collaboration in support of evidence-based policymaking.

Institutional and policy bottlenecks to IPM

This paper summarises institutional and policy bottlenecks to IPM in Africa. Agricultural policy in Africa generally prioritises production and productivity above environmental sustainability, so the use of synthetic pesticides for controlling pests is encouraged. Funding for research in IPM is limited, and extension systems struggle to provide the level of farmer support that adoption of IPM often needs. Improved research and extension policies could facilitate uptake of IPM. Public and private food-safety standards can incentivise adoption, but currently this is mainly in production for export. Pesticide and other input regulatory systems unintentionally constrain adoption of IPM, through expensive registration procedures, weak compliance monitoring and limited regional harmonisation. IPM must be seen as a key element of food-system transformation.

Implementation of Harmonized Food Consumption Data Collection in the Balkan Region According to the EFSA EU Menu Methodology Standards

Initiatives in the Capacity Development in Nutrition Research in the Balkan region in the last decade have been toward the creation of contemporary, harmonized Research Infrastructure (RI) compliant with European standards. This study describes the process of creation and implementation of the European Food Safety Authority (EFSA) EU Menu methodology in the Balkan region during the EFSA support projects for food consumption data collection in four countries (Serbia, Montenegro, Bosnia and Herzegovina, and North Macedonia). This process entailed the application and improvement of an innovative tool, the DIET ASSESS and PLAN (DAP), a platform for standardized food consumption data collection and dietary intake assessment. DAP comprises computerized food consumption, anthropometric measurements, and physical activity questionnaires, validated food picture book, and FoodEx2 exposure hierarchy with sets of facet descriptors of the interest. It hosts the Balkan food platform with a Serbian food composition database (FCDB) and Regional FCDB, compliant with European Food Information Resource (EuroFIR™) standards. The implementation of the DAP platform in national dietary surveys conducted with the support of the EFSA EU Menu project in Balkan countries enabled harmonized food consumption data compilation and reporting. Application of the methodology entailed the development of study protocol and extensive education and training of study personnel. The entire data collection process was managed by internal and external survey coordinators. A pilot study was conducted to test the entire data collection and control process and was afterward used to make necessary improvements and adjustments to meet EU Menu requirements. Data collected are internationally comparable with food consumption data in other European countries within the framework of the EU Menu program. The existence of such data in the Balkan region will catalyze research activities in emerging topics, such as identification of dietary patterns, the establishment of national nutrient reference values and food-based dietary guidelines (not only in Serbia, but in the whole Balkan region), dietary exposure assessments, the endorsement and evaluation of new food legislations, the environmental and other effects of diet on the food system. The developed and implemented methodology underpins evidence-based policy-making processes lacking in the field of public health nutrition in the region.
