Improving diets with wild and cultivated biodiversity from across the landscape

This paper examines the literature on how biodiversity contributes to improved and diversified diets in developing countries. We assess the current state of evidence on how wild and cultivated biodiversity in all forms is related to healthy diets and nutrition, and examine how economic factors, knowledge and social norms interact with availability of biodiversity to influence both production and consumption choices. The paper identifies areas where evidence is lacking and ways to build synergies between nutrition-sensitive approaches and efforts to ensure sustainability of food systems and the natural environment

Sustainable development goal 2: improved targets and indicators for agriculture and food security

The pursuit of global food security and agricultural sustainability, the dual aim of the second Sustainable Development Goal (SDG-2), requires urgent and concerted action from developing and developed countries. This, in turn, depends on clear and universally applicable targets and indicators which are partially lacking. The novel and complex nature of the SDGs poses further challenges to their implementation on the ground, especially in the face of interlinkages across SDG objectives and scales. Here we review the existing SDG-2 indicators, propose improvements to facilitate their operationalization and illustrate their practical implementation in Nigeria, Brazil and the Netherlands. This exercise provides insights into the concrete actions needed to achieve SDG-2 across contrasting development contexts and highlights the challenges of addressing the links between targets and indicators within and beyond SDG-2. Ultimately, it underscores the need for integrated policies and reveals opportunities to leverage the fulfillment of SDG-2 worldwide

How and where global food supplies fall short of healthy diets: Past trends and future projections, 1961-2020 and 2010-2050

Most of the world still lacks access to sufficient quantities of all food groups needed for an active and healthy life. This study traces historical and projected changes in global food systems toward alignment with the new Healthy Diet Basket (HDB) used by UN agencies and the World Bank to monitor the cost and affordability of healthy diets worldwide. We use HDB as a standard to measure adequacy of national, regional and global supply-demand balances, finding substantial but inconsistent progress toward closer alignment with dietary guidelines, with large global shortfalls in fruits, vegetables, and legumes, nuts, and seeds, and large disparities among regions in use of animal source foods. Projections show that additional investments in the supply of agricultural products would modestly accelerate improvements in adequacy where shortfalls are greatest, revealing the need for complementary investments to increase purchasing power and demand for under-consumed food groups especially in low-income countries

Environmental impacts, nutritional profiles, and retail prices of commonly sold retail food items in 181 countries: an observational study

Affordability is often seen as a barrier to consuming sustainable diets. This study provides the first worldwide test of how retail food prices relate to empirically estimated environmental impacts and nutritional profile scores between and within food groups. We use prices for 811 retail food items commonly sold in 181 countries during 2011 and 2017, matched to estimated carbon and water footprints and nutritional profiles, to test whether healthier and more environmentally sustainable foods are more expensive between and within food groups. We find that within almost all groups, less expensive items have significantly lower carbon and water footprints. Associations are strongest for animal source foods, where each 10% lower price is associated with 20 grams lower CO2-equivalent carbon and 5 liters lower water footprint per 100kcal. Gradients between price and nutritional profile vary by food group, price range, and nutritional attribute. In contrast, lower-priced items have lower nutritional value in only some groups over some price ranges, and that relationship is sometimes reversed. These findings reveal opportunities to reduce financial and environmental costs of diets, contributing to transitions towards healthier, more environmentally sustainable food systems

The cost and affordability of preparing a basic meal around the world

All countries have a rising burden of diet-related disease from the consumption of unhealthy foods. About three billion people around the world cannot afford the diverse foods needed for a healthy diet. This chapter aims to extend previous work on diet cost and affordability to address the hidden costs of meal preparation inside the home. Costs of a basic meal based on market prices for the most affordable items are estimated in 168 countries. Also, the hidden costs of meal preparation are considered, taking account of environmental or social externalities from the production and distribution of food, as well as the health externalities involved in food consumption. The data shown here reveal that even the simple raw ingredients for a basic plate are often unaffordable for the poorest, and the added cost of time and fuel can make such meals prohibitively expensive. Results suggest two main avenues for policy action. First, governments should use the information on the least costly way to meet dietary standards to inform poverty lines and provide targeted assistance so as to ensure that citizens can acquire safe and nutritious items in sufficient quantities for an active and healthy life, using locale-appropriate safety nets. Second, food policies should recognize the hidden costs of meal preparation that often put healthier, more sustainable diets out of reach. Overcoming the hidden barriers to preparation of healthy meals will require support for helpful forms of food processing that preserve or enhance nutritional values, while taking action to limit potentially harmful forms of ultra-processing associated with diet-related disease. Food-based safety nets and improvements in the food environment can make healthy diets affordable for all people at all times, to help every country reach global development goals.https://link.springer.com/book/10.1007/978-3-031-15703-5hj2024Agricultural Economics, Extension and Rural DevelopmentSDG-01:No povertySDG-02:Zero Hunge

Leveraging agriculture for nutrition in South Asia and East Africa: examining the enabling environment through stakeholder perceptions

South Asia and sub-Saharan Africa are the two regions of the world with the highest concentration of undernutrition. The majority of the nutritionally vulnerable populations in both regions is dependent in some way upon agriculture as a primary source of livelihood. The agriculture sector and wider agri-food system is considered to be central to sustained progress in reducing undernutrition – and yet not enough is known about how to unleash this potential. Recent scoping assessments have also revealed a paucity of information on wider political, institutional and policy-related challenges relating to the agriculture-nutrition nexus globally. Contextualized research into policy processes and the political economy of agriculture and nutrition is needed to better characterize “enabling environments” for agriculture to benefit nutrition, and how these environments can be shaped and sustained. This study aims to contribute to filling this gap, by drawing upon evidence from a set of case studies in South Asia (India, Bangladesh and Pakistan) and eastern Africa (Ethiopia, Uganda and Kenya). In synthesizing results across countries, while recognizing important nuance and detail, we conclude by highlighting four key issues to be addressed. First, improving knowledge and perception of undernutrition and its links to agriculture, on the part of agricultural policymakers and programme managers. Second, generating system-wide incentives for decisions and actions to become more pro-nutrition. Third, developing transparent systems of accountability for nutrition-relevant action throughout the agriculture sector, through linking timely and actionable data and evidence with incentives. And fourth, cultivating and strengthening leadership and capacities at different levels, underpinned by adequate financing.UK AidDepartment for International Development (DFID

Replacement of Contentious Inputs in Organic Farming Systems (RELACS) – a comprehensive Horizon 2020 project

Organic farmers adhere to high standards in producing quality food while protecting the environment. However, organic farming needs to improve continuously to keep meeting its ambitious objectives. The project ‘Replacement of Contentious Inputs in Organic Farming Systems’ (RELACS) will foster the development and adoption of cost-efficient and environmentally safe tools and technologies to further reduce the use of external inputs on organic farms across Europe as well as in Non EU Mediterranean countries. Project partners will provide scientific support to develop fair and implementable EU rules to improve current practices in organic farming. Farm advisory networks in 11 European countries will reach out to farmers to ensure effective dissemination and adoption of the tools and techniques

Gaps and priorities in assessment of food environments for children and adolescents in low- and middle-income countries

School-aged children and adolescents have complex interactions with their food environments—the point of engagement of individuals with the food system—and are influenced by a diversity of individual, household and organizational factors. Although a wide range of methods have been proposed to define, monitor and evaluate food environments, few are tailored to school-aged children and adolescents. Here, we interrogate published literature on food metrics and methodologies for the characterization of food environments for school-aged children and adolescents living in low- and middle-income counties. We identify key priority actions and potential indicators for better monitoring and evaluation to galvanize policymaking to improve the healthiness of these interactions, which are so crucial to future adult well-being

Reverse thinking: taking a healthy diet perspective towards food systems transformations

Food systems that deliver healthy diets without exceeding the planet’s resources are essential to achieve the worlds’ ambitious development goals. Healthy diets need to be safe, accessible, and affordable for all, including for disadvantaged and nutritionally vulnerable groups such as of smallholder producers, traders, and consumers in low- and middle-income countries. Globally, food systems are experiencing rapid and drastic changes and are failing to fulfil these multiple duties simultaneously. The international community therefore calls for rigorous food systems transformations and policy solutions to support the achievement of healthy diets for all. Most strategies, however, are essentially supply- and market-oriented. Incorporation of a healthy diet perspective in food system transformation is essential to enable food systems to deliver not only on supplying nutritious foods but also on ensuring that consumers have access can afford and desire healthy, sustainable, and culturally acceptable diets. This paper argues that this should be guided by information on diets, dietary trends, consumer motives, and food environment characteristics. Transformational approaches and policies should also take into account the stage of food system development requiring different strategies to ensure healthier diets for consumers. We review current knowledge on drivers of consumer choices at the individual and food environment level with special emphasis on low- and middle income countries, discuss the converging and conflicting objectives that exist among multiple food-system actors, and argue that failure to strengthen synergies and resolve trade-offs may lead to missed opportunities and benefits, or negative unintended consequences in food system outcomes. The paper proposes a menu of promising consumer- and food-environment- oriented policy options to include in the food systems transformation agenda in order to shift LMIC consumer demand towards healthier diets in low- and middle income countries
