Local and regional food production diversity are positively associated with household dietary diversity in rural Africa.

Undernutrition and low dietary quality remain widespread issues in Africa. As most rural households in the region are involved in farming, the diversification of own farm production could improve their access to nutritious foods. Here we use representative panel data from six African countries to estimate this effect across different scales.

Animal-sourced foods improve child nutrition in Africa.

Child undernutrition remains a widespread public health problem in the Global South, especially in Africa. Childhood stunting-meaning linear growth retardation-is a comprehensive and commonly used indicator of chronic child undernutrition and is mostly the result of insufficient nutrient intake, among other factors. Previous research showed that the consumption of animal-sourced foods (ASF), including meat, dairy, eggs, and fish, is associated with lower rates of child stunting, but reliable evidence for Africa is scant.

Positive public attitudes towards agricultural robots.

Robot technologies could lead to radical changes in farming. But what does the public know and think about agricultural robots? Recent experience with other agricultural technologies-such as plant genetic engineering-shows that public perceptions can influence the pace and direction of innovation, so understanding perceptions and how they are formed is important. Here, we use representative data from an online survey (n = 2269) to analyze public attitudes towards crop farming robots in Germany-a country where new farming technologies are sometimes seen with skepticism.

Transformation scenarios towards multifunctional landscapes: A multi-criteria land-use allocation model applied to Jambi Province, Indonesia.

In tropical regions, shifting from forests and traditional agroforestry to intensive plantations generates conflicts between human welfare (farmers' demands and societal needs) and environmental protection. Achieving sustainability in this transformation will inevitably involve trade-offs between multiple ecological and socioeconomic functions. To address these trade-offs, our study used a new methodological approach allowing the identification of transformation scenarios, including theoretical landscape compositions that satisfy multiple ecological functions (i.

Mobile phones, women's physical mobility, and contraceptive use in India.

Women's economic and social empowerment is facilitated by their ability to move around independently and safely. However, in many developing countries women's physical mobility is restricted by social norms, structural impediments related to poor quality of roads and transport systems, and security issues. Restrictions on female physical mobility and low levels of empowerment can also have negative implications for women's access to healthcare services.

Farm-level production diversity and child and adolescent nutrition in rural sub-Saharan Africa: a multicountry, longitudinal study.

Background: Child malnutrition remains widespread in sub-Saharan Africa, especially in rural areas where many households are involved in subsistence farming. Increasing farm-level production diversity (FPD) is often considered a useful strategy to improve child diets and nutrition, but the empirical evidence is mixed. Most studies have investigated associations between FPD and dietary diversity.

Genetically modified crops support climate change mitigation.

Genetically modified (GM) crops can help reduce agricultural greenhouse gas (GHG) emissions. In addition to possible decreases in production emissions, GM yield gains also mitigate land-use change and related emissions. Wider adoption of already-existing GM crops in Europe could result in a reduction equivalent to 7.

Personalized digital extension services and agricultural performance: Evidence from smallholder farmers in India.

Productivity growth in smallholder agriculture is an important driver of rural economic development and poverty reduction. However, smallholder farmers often have limited access to information, which can be a serious constraint for increasing productivity. One potential mechanism to reduce information constraints is the public agricultural extension service, but its effectiveness has often been low in the past.

Sustainability standards in global agrifood supply chains.

Agrifood supply chains contribute to many environmental and social problems. Sustainability standards-rules that supply chain actors may follow to demonstrate their commitment to social equity and/or environmental protection-aim to mitigate such problems. We provide a narrative review of the effects of many distinct sustainability standards on different supply chain actors spanning multiple crops.

Europe's Farm to Fork Strategy and Its Commitment to Biotechnology and Organic Farming: Conflicting or Complementary Goals?

The European Commission's Farm to Fork (F2F) strategy, under the European Green Deal, acknowledges that innovative techniques, including biotechnology, may play a role in increasing sustainability. At the same time, organic farming will be promoted, and at least 25% of the EU's agricultural land shall be under organic farming by 2030. How can both biotechnology and organic farming be developed and promoted simultaneously to contribute to achieving the Sustainable Development Goals (SDGs)? We illustrate that achieving the SDGs benefits from the inclusion of recent innovations in biotechnology in organic farming.

Africa's Changing Food Environments and Nutritional Effects on Adults and Children.

Many low- and middle-income countries (LMICs) are experiencing profound changes in food environments, including a rapid growth of supermarkets and other modern retailers. Changing food environments can influence people's diets, nutrition, and health. While in many LMICs, undernutrition and micronutrient deficiencies are still widespread, problems of overweight, obesity, and related non-communicable diseases are also massively on the rise.

Multiplying the efficiency and impact of biofortification through metabolic engineering.

Ending all forms of hunger by 2030, as set forward in the UN-Sustainable Development Goal 2 (UN-SDG2), is a daunting but essential task, given the limited timeline ahead and the negative global health and socio-economic impact of hunger. Malnutrition or hidden hunger due to micronutrient deficiencies affects about one third of the world population and severely jeopardizes economic development. Staple crop biofortification through gene stacking, using a rational combination of conventional breeding and metabolic engineering strategies, should enable a leap forward within the coming decade.

Effects of Modern Food Retailers on Adult and Child Diets and Nutrition.

In many developing countries, food environments are changing rapidly, with modern retailers-such as supermarkets-gaining in importance. Previous studies have suggested that the rise of modern retailers contributes to overweight and obesity. Effects of modern retailers on dietary quality have not been analyzed previously due to the unavailability of individual-level dietary data.

Options to Reform the European Union Legislation on GMOs: Post-authorization and Beyond.

We discuss options to reform the EU genetically modified organism (GMO) regulatory framework, make risk assessment and decision-making more consistent with scientific principles, and lay the groundwork for international coherence. In this third of three articles, we focus on labeling and coexistence as well as discuss the political reality and potential ways forward.

Options to Reform the European Union Legislation on GMOs: Risk Governance.

Here, we discuss options to reform the EU genetically modified organism (GMO) regulatory framework, to make risk assessment and decision-making more consistent with scientific principles, and to lay the groundwork for international coherence. We discussed the scope and definitions in a previous article and, thus, here we focus on the procedures for risk assessment and risk management.

Trade-offs between multifunctionality and profit in tropical smallholder landscapes.

Land-use transitions can enhance the livelihoods of smallholder farmers but potential economic-ecological trade-offs remain poorly understood. Here, we present an interdisciplinary study of the environmental, social and economic consequences of land-use transitions in a tropical smallholder landscape on Sumatra, Indonesia. We find widespread biodiversity-profit trade-offs resulting from land-use transitions from forest and agroforestry systems to rubber and oil palm monocultures, for 26,894 aboveground and belowground species and whole-ecosystem multidiversity.

Options to Reform the European Union Legislation on GMOs: Scope and Definitions.

We discuss options to reform the EU genetically modified organisms (GMO) regulatory framework, make risk assessment and decision-making more consistent with scientific principles, and lay the groundwork for international coherence. The first in a three-part series, this article focuses on reform options related to the scope of the legislation and the GMO definition.

Various forms of double burden of malnutrition problems exist in rural Kenya.

Background: The coexistence of overweight/obesity and undernutrition is often referred to as the double burden of malnutrition (DB). DB was shown to exist in many developing countries, especially in urban areas. Much less is known about DB in rural areas of developing countries.

Transgenic cotton and farmers' health in Pakistan.

Despite substantial research on the economic effects of transgenic insect-resistant Bacillus thuringiensis (Bt) cotton, there is still limited work on this technology's impacts on human health. Due to the inbuilt insect resistance, Bt cotton requires fewer pesticide sprays than conventional cotton, which is not only advantageous from economic and environmental perspectives, but may also result in health benefits for farmers. Using socioeconomic and biophysical data from Pakistan, we provide the first evidence of a direct association between Bt gene expression in the plant and health benefits.

Intensive tropical land use massively shifts soil fungal communities.

Soil fungi are key players in nutrient cycles as decomposers, mutualists and pathogens, but the impact of tropical rain forest transformation into rubber or oil palm plantations on fungal community structures and their ecological functions are unknown. We hypothesized that increasing land use intensity and habitat loss due to the replacement of the hyperdiverse forest flora by nonendemic cash crops drives a drastic loss of diversity of soil fungal taxa and impairs the ecological soil functions. Unexpectedly, rain forest conversion was not associated with strong diversity loss but with massive shifts in soil fungal community composition.
