  • Rapid breeding and varietal replacement are critical to adaptation of
           cropping systems in the developing world to climate change

      Plant breeding is a key mechanism for adaptation of cropping systems to climate change. Much discussion of breeding for climate change focuses on genes with large effects on heat and drought tolerance, but phenology and stress tolerance are highly polygenic. Adaptation will therefore mainly result from continually adjusting allele frequencies at many loci through rapid-cycle breeding that delivers a steady stream of incrementally improved cultivars. This will require access to elite germplasm from other regions, shortened breeding cycles, and multi-location testing systems that adequately sample the target population of environments. The objective of breeding and seed systems serving smallholder farmers should be to ensure that they use varieties developed in the last 10 years. Rapid varietal turnover must be supported by active dissemination of new varieties, and active withdrawal of obsolete ones. Commercial seed systems in temperate regions achieve this through competitive seed markets, but in the developing world, most crops are not served by competitive commercial seed systems, and many varieties date from the end of the Green Revolution (the late 1970s, when the second generation of modern rice and wheat varieties had been widely adopted). These obsolete varieties were developed in a climate different than today's, placing farmers at risk. To reduce this risk, a strengthened breeding system is needed, with freer international exchange of elite varieties, short breeding cycles, high selection intensity, wide-scale phenotyping, and accurate selection supported by genomic technology. Governments need to incentivize varietal release and dissemination systems to continuously replace obsolete varieties.

      The Indian state of Odisha has made significant strides to address health and nutrition in the last 25 years. We used public data, policy and program documents, published literature, and interviews (n=75) with program and policy decision-makers, representatives from development partners, and civil society and community members to analyze these changes. Factors that contributed to scale up of health and nutrition interventions and the food security program included overarching policy support, financing at the national and state level, leadership across sectors from government to civil society and development partners, capacity and stability of tenure of bureaucrats, and state innovations in service delivery interventions. Barriers that may impede further progress include lack of sanitation, low levels of women's education, early marriage in girls, livelihood distress, and uneven progress across social groups.

      Biofortification is a feasible and cost-effective means of delivering micronutrients to populations that may have limited access to diverse diets and other micronutrient interventions. Since 2003, HarvestPlus and its partners have demonstrated that this agriculture-based method of addressing micronutrient deficiency through plant breeding works. More than 20 million people in farm households in developing countries are now growing and consuming biofortified crops. This review summarizes key evidence and discusses delivery experiences, as well as farmer and consumer adoption. Given the strength of the evidence, attention should now shift to an action-oriented agenda for scaling biofortification to improve nutrition globally. To reach one billion people by 2030, there are three key challenges: 1) mainstreaming biofortified traits into public plant breeding programs; 2) building consumer demand; and 3) integrating biofortification into public and private policies, programs, and investments. While many building blocks are in place, institutional leadership is needed to continue to drive towards this ambitious goal.

      Though reducible by known means, food insecurity remains widespread, with tightening constraints on alternative policies to address it. In this article, we argue that in many developing countries more equal distribution of land is a key, yet often neglected, policy option, and that state-led land reform remains a major, ethically defensible route for addressing food insecurity and related disadvantages. In assessing empirically and ethically redistributive land reform to smallholders, we seek to advance the debate in global food security and to make a contribution to farmland-access ethics, that is, the moral evaluation of actions, practices, policies, and laws that affect farmland distribution, allocation, and use.

  • Production potential in the “bread baskets” of Eastern Europe
           and Central Asia

      Eastern Europe and Central Asia is a major food producer and exporter. Almost a quarter of world wheat exports come from the region, and especially from Kazakhstan, Russia and Ukraine (RUK). The potential of these countries to become a “bread basket” for the world has been emphasized because of already large production and exports and their “immense land and yield reserves”, referring to the abandonment of more than 50 million hectares of cropland and the large drop in crop productivity in the 1990s. However, there is considerable uncertainty about the potential of this land for food production. In this paper we review interdisciplinary literature and empirical evidence, predictions of production potential and impacts of climate change; and discuss the potential of the region to become a reliable breadbasket of the world. From a biophysical (crop growth) perspective, under different scenarios of increased yields, land use and climate change effects, RUK could produce an additional 40–110 million tons of wheat compared to current production, which would be a substantial additional production. However economic incentives, in particular the evolution of food prices and competition from other crops, are likely to significantly constrain these potentials. In addition, the introduction of export restrictions during recent times of high prices raised concerns on the reliability of RUK as exporters.

      The objective of this article is to identify, describe and analyze elements of food security governance in Mexico. As in other emerging nations, tension in Mexico is mounting between the imperatives of obtaining food security – now consecrated by the constitution as a fundamental human right – and the formal governance structure of the agricultural sector. The logic of government (and of power) is markedly vertical. However, this clearly contradicts the inherently horizontal and cross-cutting nature of food policies or, more accurately stated, the imperative of satisfying food security needs. In Mexico, the diverse food, nutrition and public health issues are handled separately by different agencies with highly unequal capacities for action and political power. Fragmentation creates confusion and, we hypothesize, is largely responsible for the extremely weak state of food security governance in Mexico. Additionally, the food and marketing industry is gaining ground and is now a larger contributor to Mexico's GDP than agriculture. Mexico's agro-industrial sector is undergoing acute oligopoly problems that threaten the entire agro-industrial chain and food security as a whole. Conclusion Mexico currently lacks a national food and nutrition strategies that ensure food security for the Mexican people. The time has come to consider implementing either permanent or long-term strategies that will make it possible to evaluate and reflect upon what does/not work in the area of food and nutrition governance.

      This paper brings together existing literature on the Mahatma Gandhi National Rural Employment Guarantee Act (MGNRGEA) and the Public Distribution System (PDS) in India, offering a narrative review of the evidence on impacts on food security, health and nutrition of beneficiaries. Both programs operate on a large scale and have the capacity to impact the factors leading to undernutrition. It is evident that despite the deficiencies in implementation, both the MGNREGA and the PDS are inclusive and reach the poor and the marginalized, who are likely to also experience greater undernutrition and poor health. Data challenges have however prevented researchers from conducting studies that assess the ultimate impact of these two large-scale programs on health and nutrition. The evidence that exists suggests largely positive impacts indicating a clear potential to make these programs more nutrition sensitive not just by incorporating elements that would explicitly address nutritional concerns but also by directing specific attention to innovations that strengthen critical complementarities and synergies that exist between the two programs.

      Food Policy, in much of Asia, has been slow to transition from its historic focus on staple grain self-sufficiency to a more integrated approach to nutrition security. Research and policy discussions continue to focus on hunger and calorie deficiency rather than on the need for a balanced diets to address chronic micronutrient malnutrition and the emerging problems of over weight and obesity. Social welfare schemes aimed at improving nutrition also focus on ensuring calorie sufficiency, neglecting quality and diversity of diets and behavioral change towards better nutrition. This paper provides a detailed review of the evolution of food policy in India and a way forward in the transition towards nutrition security.

      Marine biotoxins are mostly produced by phytoplankton. Proliferation of algae producing marine biotoxins, also known as harmful algal bloom (HAB), occurs worldwide. Such event depends on environmental conditions, including temperature, water pH/salinity, current patterns and anthropogenic nutrient input. Marine biotoxins can accumulate in seafood products and as such present a threat to consumers. This paper reviews and compiles up-to-date literature on reported human intoxications following exposure to marine biotoxins through seafood consumption. The review includes a discussion about prevention of such outbreaks and surveillance programs to identify possible limitations and approaches for limiting the impact of HABs on human health. It is concluded that marine biotoxins represent a threat to human health as thousands of poisonings following consumption of seafood contaminated with marine biotoxins were reported in the 21st century, emphasizing the need for carrying on/developing surveillance programs to detect the presence of HABs, and for development, validation and implementation of sensitive high-throughput methods for detecting these biotoxins in seafood to protect consumers. Regarding the possible presence of unknown toxins and general lack of standards for many known toxins, in vitro effect-based bioassays may play an important role in the monitoring for biotoxins.

      Small-scale poultry production systems are mostly found in rural, resource-poor areas that often also experience food insecurity. They are accessible to vulnerable groups of society, and provide households with income and nutritionally-rich food sources. However, they also improve food security in indirect ways, such as enhancing nutrient utilisation and recycling in the environment, contributing to mixed farming practices, contributing to women's empowerment, and enabling access to healthcare and education. Further, they may contribute to several of the Sustainable Development Goals, and to future food security through maintaining biodiverse genomes. In extensive small-scale poultry production systems, significant impediments to achieving these contributions are disease and predation, which can be reduced through improved agricultural and livestock extension and community animal health networks. For small-scale intensive systems, feed price fluctuations and inadequate biosecurity are major constraints.

      Reduction of global food insecurity depends upon the mobilization of genetic diversity for agricultural research and innovation. Yet increased regulation of genetic materials is profoundly affecting the way agricultural research is conducted, particularly international research that requires access to diverse germplasm. This study draws from an international survey of researchers in USAID Feed the Future Innovation Labs to understand how regulations affect access, exchange and use of genetic material within an international collaborative research environment. Although the effects of regulation depend on the research context – crop, sector, collaborative relationships, country and institutional source – transaction costs are increasing and researchers are changing strategies to access genetic material. The new regulatory environment is merging a traditional informal exchange system, perceived to be more open, with a more formal system that sets rules on access and use of genetic materials to address social, economic and environmental goals.

      There is a deficit of mineral micronutrients in global food systems, known as ‘hidden hunger’, especially in the global south. This review focuses on zinc (Zn) and iron (Fe), whose entry into food systems depends primarily on soil and crop factors. Approaches to increase dietary supplies of Zn and Fe include: (1) supplementation, (2) food fortification, (3) dietary diversification, and (4) crop biofortification, including breeding and fertilizer-based approaches. Supply-based estimates indicate that Zn deficiency might be more widespread than Fe deficiency in sub-Saharan Africa, although there are major knowledge gaps at an individual biomarker level. Recent analytical advances, including the use of stable isotopes of Zn and Fe, can play an increasing role in improving our understanding of the movement of micronutrients in food systems, and thereby help to reduce the immense human cost of ‘hidden hunger’.

      Animal products, i.e. meat, milk and eggs, provide an important component in global diets, but livestock dominate agricultural land use by area and are a major source of greenhouse gases. Cultural and personal associations with animal product consumption create barriers to moderating consumption, and hence reduced environmental impacts. Here we review alternatives to conventional animal products, including cultured meat, imitation meat and insects (i.e. entomophagy), and explore the potential change in global agricultural land requirements associated with each alternative. Stylised transformative consumption scenarios where half of current conventional animal products are substituted to provide at least equal protein and calories are considered. The analysis also considers and compares the agricultural land area given shifts between conventional animal product consumption. The results suggest that imitation meat and insects have the highest land use efficiency, but the land use requirements are only slightly greater for eggs and poultry meat. The efficiency of insects and their ability to convert agricultural by-products and food waste into food, suggests further research into insect production is warranted. Cultured meat does not appear to offer substantial benefits over poultry meat or eggs, with similar conversion efficiency, but higher direct energy requirements. Comparison with the land use savings from reduced consumer waste, including over-consumption, suggests greater benefits could be achieved from alternative dietary transformations considered. We conclude that although a diet with lower rates of animal product consumption is likely to create the greatest reduction in agricultural land, a mix of smaller changes in consumer behaviour, such as replacing beef with chicken, reducing food waste and potentially introducing insects more commonly into diets, would also achieve land savings and a more sustainable food system.

      After a period of relative success in generating political momentum to address malnutrition, there is an increasing urgency to focus on implementation and impact on the ground. This requires better documentation of the experiences of policymakers, nutrition leaders, program managers and implementers in making decisions on what to do in real time, such as coordinating and implementing multisectoral nutrition plans in dynamic country contexts. The goal of the Stories of Change (SoC) initiative is to foster and support such experiential learning by systematically assessing and analyzing drivers of change in six high-burden contexts (Ethiopia, Zambia, Senegal, Bangladesh, Nepal and Odisha, India) that have had some success in accelerating improvements in nutrition. While recognizing context-specificity, we unpack the key pre-requisites (commitment, coherence, accountability, data, leadership, capacity and finance) that fuel and sustain progress.

      A segment of the Brazilian population lives in households experiencing severe food insecurity (SFI). We used logistic regression models to assess the secular trend of SFI in Brazilian municipalities, between the years of 2004 and 2013. At the state-level, there was a reduction of the prevalence of SFI during this period, with reduction rates ranging from −2.5% to −75.2% with only one state showing positive increase in SFI. The inter and intra-regional/state variation of SFI found in 2004 remained in 2013, although it was less pronounced. Brazil is currently experiencing a serious economic and political crisis that calls for continuing monitoring of SFI. This study is very relevant for the rest of the world as it shows that experience based food security scales can provide a very useful indicator for policy makers as it can track severe SFI across time from the national to the municipal level.

      The dissemination of improved rice varieties could contribute significantly to achieving food security and reducing poverty in sub-Saharan Africa (SSA). This study assesses the number of households and individuals lifted out of poverty and food insecurity. Metadata and primary data collected from sixteen countries were analyzed. A positive impact of improved varieties on food security and poverty reduction was observed over the period 2000–2014. In addition, the rate of adoption of these varieties increased over these years and this increase was more significant after the 2008 food crisis. Average income also increased from US$ 25 capita–1 to US$ 58 capita–1 for NERICA adopters. These trends could be enhanced by addressing production constraints and certified seed bottlenecks.

      In the past 15 years, Senegal has made considerable progress in the fight against child undernutrition. To better understand how this was achieved, we reviewed 11 national policy documents published between 2001 and 2015, and interviewed 25 key-informants from the government, donor community, civil society, as well as 24 local service providers and 18 community members. We explored the commitment of actors and coherence between and within sectors. We linked this to changes in nutrition services experienced by communities. The key theme that emerged was the critical role of increased political commitment, materialized and maintained by a high-level national coordinating body for nutrition. The body actively facilitates multisectoral coherence in action for nutrition, overseeing the implementation of a national nutrition program, the effects of which are seen at the community level.

      An enabling environment for malnutrition reduction includes creating policy and political momentum, and converting momentum to implementation and impact. We used several qualitative data sources to investigate changes in policy and action over time in Zambia. There now exists coherent policy covering key nutrition issues from several sectors, and multisectoral coordination structures at national level and in pilot districts. However, converting momentum into action faces challenges of limited national political and funding commitment, with increased donor resources currently bridging the gap, and reach into communities is still limited. To sustain recent stunting reductions there are still political challenges to be addressed in Zambia, and citizens and civil society will need to hold government to account for recent commitments on nutrition.

      Orange-fleshed sweetpotato (OFSP) is a rich plant-based source of beta-carotene, which the body converts into vitamin A. In sub-Saharan Africa, sweetpotato is known as a food security crop but most varieties grown are high dry matter white-fleshed types, lacking beta-carotene. In 1995, researchers recognized the potential of OFSP varieties to address widespread vitamin A deficiency in SSA using an integrated agriculture-nutrition approach. With their partners, they confronted conventional wisdom concerning food-based approaches and institutional barriers, to build the evidence base and breed 42 OFSP varieties adapted to farmer needs and consumer preferences. Subsequently, a multi-partner, multi-donor initiative, launched in 2009, has already reached 2.8 million households. This review summarizes that effort describing how the changing policy environment influenced the process.

      Bangladesh has made considerable progress in reducing child stunting and is lauded as a success story in global nutrition fora. This mixed-methods study considers available statistical and qualitative evidence to help reveal the critical factors behind Bangladesh's ‘story of change’ in nutrition. Much of the improvement in nutrition in Bangladesh in recent years is explained by what can be seen as nutrition-sensitive drivers within a wider enabling environment of pro-poor economic growth. Key amongst these factors have been improving incomes; smaller family sizes and greater gaps between births; parental - and particularly women's - education and wider health access. Research and interviews with key stakeholders and work at a community level has helped shed light on the policy and programmatic choices which lie behind these wider determinants. Community based nutrition programmes have not yet been operating at scale as in other countries and the current governance arrangements for nutrition delivery are weak. But as Bangladesh faces growing new nutritional problems and still suffers from a relatively high burden of child stunting, such ‘nutrition-specific’ programmes will have to play a greater role than in the past, as the further gains from some of these wider drivers may be limited and are likely to have plateaued.

      Over the past two decades, many developing countries have made impressive progress in reducing undernutrition. We explore potential explanations of this success by applying consistent statistical methods to multiple rounds of Demographic Health Surveys for Bangladesh, Nepal, Ethiopia, Odisha, Senegal, and Zambia. We find that changes in household wealth, mother's education and access to antenatal care are the largest drivers of nutritional improvement, except for Zambia where large increases in bednet usage is the single largest factor. Other factors play a smaller role in explaining nutritional improvements with improvements in sanitation only appearing to be important in South Asia. Overall, the results point to the need for multidimensional nutritional strategies involving a broad range of nutrition-sensitive sectors.

      In developing countries, invasive alien species (IAS) threaten smallholder farmer production and the food security of subsistence growers, but economic impacts are widely under-reported. Here, the economic impacts of IAS that threaten smallholder mixed maize farming in eastern Africa are presented. Maize is important for most smallholders and is commonly grown with horticultural crops and other cereals which collectively provide nutrition and income. These crops are also important for national economies. Estimates of the economic impacts of five major IAS: Chilo partellus, Maize Lethal Necrosis Disease, Parthenium hysterophorus, Liriomyza spp. and Tuta absoluta on mixed maize smallholders in six countries gave current combined annual losses of US$0.9–1.1 billion; and future annual losses (next 5–10 years) of US$1.0–1.2 billion.

      Changes in the immediate, underlying and basic determinants of nutritional status at the community- and household-level are a logical and empirical prerequisite to reducing high levels of undernutrition in high burden countries. This paper considers these factors directly from the perspective of community members and frontline workers interviewed in six countries in South Asia and sub-Saharan Africa. In each country, in-depth interviews were conducted with mothers, other community members and health workers to understand changes in health and nutrition practices, nutrition-specific interventions, underlying drivers and nutrition-sensitive interventions, and life conditions. Overall, the need for basic improvements in livelihood opportunities and infrastructure are solidly underscored. Nutrition-specific and -sensitive changes represented in most cases by deliberate government or NGO supported community interventions are rolling out at a mixed and uneven pace, but are having some significant impacts where solidly implemented. The synthesis presented here provides an invaluable source of information for understanding how community-level change occurred against a wider backdrop of national level progress.

      This paper explores the drivers of Nepal's maternal and child nutrition success using document review, interviews with mothers, and quantitative analysis of DHS datasets. Our qualitative and quantitative analyses both highlight similar policy and community level changes but limited improvements in child feeding and care practices. Improvements in four key drivers of nutritional change emerged: health services, sanitation, education, and wealth. However, the relative contributions of each factor varied by indicator, with health services more important for linear growth among children, and sanitation more important for weight gain among both children and mothers. We conclude with a discussion bringing the qualitative and quantitative findings together into key lessons from Nepal's success.

      This paper provides an analysis of mid-level actors and their operating environments in relation to implementing nutrition-sensitive programming in Ethiopia. We used an innovative, multi-sited qualitative method encompassing the group of implementing actors in health, agriculture, and social protection below regional level and a sample of households from a community receiving these government services. Systemic constraints and day-to-day operational challenges within sectoral programming characterized the mid-level operating environment. Communities experienced nutrition-related improvements over time, but were constrained in their ability to engage with government programming by their physical environment. Mid-level actors are subject to complex constraints originating from both systemic factors and day-to-day resource constraints. Further development of existing service provision platforms and attention to community constraints is recommended to align national nutrition agendas with implementation capacities and community needs.

      China's food production depends highly on irrigation, but irrigated agriculture has been threatened by increasing water scarcity. As such, the overall goal of this study is to provide a better understanding of the changing trends in water supply and demand balance, their impacts on food production, and government policy responses. The results show that water scarcity in China is a regional issue, mainly in northern areas. This is reflected in the limited and uneven distribution of water resources, decline of surface water resources, depletion of groundwater resources, degradation of water quality and increasing water demand. Climate change has further aggravated water scarcity in several river basins in northern China, resulting in the reduction of irrigated areas and a fall in food production. Consequently, the Chinese government has tried to control total water withdrawal, improve water use efficiency, and control water pollution. While these policy responses are encouraging, their effectiveness in resolving the growing water scarcity in China needs to be examined.

      Meeting demand for food, fiber, feed, and fuel in a world with 9.7 billion people by 2050 without negative environmental impact is the greatest scientific challenge facing humanity. We hypothesize that this challenge can only be met with current and emerging technologies if guided by proactive use of a broad array of relevant data and geospatial scaling approaches to ensure local to global relevance for setting research priorities and implementing agricultural systems responsive to real-time status of weather, soils, crops, and markets. Despite increasing availability of field-scale agricultural data, robust spatial frameworks are lacking to convert these data into actionable knowledge. This commentary article highlights this knowledge gap and calls attention to the need for developing robust spatial frameworks that allow appropriate scaling to larger spatial domains by discussing a recently developed example of a data-driven strategy for estimating yield gaps of agricultural systems. To fully leverage research on sustainable intensification of cropping systems and inform policy development at different scales, we call for new approaches combining the strengths of top-down and bottom-up approaches which will require coordinated efforts between field scientists, crop modelers, and geospatial researchers at an unprecedented level.

      Livestock contribute to food security by supplying essential macro- and micro-nutrients, providing manure and draught power, and generating income. But they also consume food edible by humans and graze on pastures that could be used for crop production. Livestock, especially ruminants, are often seen as poor converters of feed into food products. This paper analyses global livestock feed rations and feed conversion ratios, with specific insight on the diversity in production systems and feed materials. Results estimate that livestock consume 6 billion tonnes of feed (dry matter) annually – including one third of global cereal production – of which 86% is made of materials that are currently not eaten by humans. In addition, soybean cakes, which production can be considered as main driver or land-use, represent 4% of the global livestock feed intake. Producing 1kg of boneless meat requires an average of 2.8kg human-edible feed in ruminant systems and 3.2kg in monogastric systems. While livestock is estimated to use 2.5 billion ha of land, modest improvements in feed use efficiency can reduce further expansion.

      In recent years, the question of food losses and waste (FLW) has been the subject of much debate. When it comes to food security, the preservation of natural resources and potential economic benefits, the general public, scientists and politicians all agree that FLW needs to be reduced. However, there are numerous inconsistencies in terms of how the problem of FLW has been presented and analysed. This article aims to highlight these inconsistencies and help identify the areas of research that could contribute to a more effective handling of FLW issues. The article examines: (i) whether the choice of definition(s) adopted are consistent with the problem(s) targeted; (ii) the efficiency of the methodologies used to address the issues raised, and (iii) the relevance of arguments put forward concerning FLW reduction.

      Micronutrient deficiencies or ‘hidden hunger’ resulting from unbalanced diets based on starchy staple crops are prevalent among the population of sub-Saharan Africa. This review discusses the effectiveness of agronomic biofortification - the application of mineral micronutrient fertilizers to soils or plant leaves to increase micronutrient contents in edible parts of crops – and it's potential to fight hidden hunger. There is evidence that agronomic biofortification can increase yields and the nutritional quality of staple crops, but there is a lack of direct evidence that this leads to improved human health. Micronutrient fertilization is most effective in combination with NPK, organic fertilizers and improved crop varieties, highlighting the importance of integrated soil fertility management. Agronomic biofortification provides an immediate and effective route to enhancing micronutrient concentrations in edible crop products, although genetic biofortification may be more cost effective in the long run.

      Food security relies on continuous supplies of improved products from plant breeding and their assimilation into agriculture. Extraordinary innovations in the life sciences have brought plant breeding into a new phase of opportunity. These include the means to discover, manage and select better versus poorer versions of genes and the ability to change gene sequences in situ by gene editing. Genomics is also revealing the thousands of different microbes in all plants and the roles that their genomes play in determining crop traits that can be further improved by addition of the right microbes. Assimilation of such innovations into breeding strategies can have major impacts on rates of breeding gain but to achieve this will require comprehensive strategic leadership, planning and investments by scientists, leading global agencies and all governments based on appreciation of (i) the continuous streams of innovations underpinning crop improvement and (ii) the necessities for more rapid crop improvements everywhere to help avert otherwise inevitable catastrophes.

      Food security is highly sensitive to climate risks in rainfed areas, particularly in South Asia where agriculture is highly dependent on rainfall. About 56% of India's land mass is agricultural land, and only 43% is net cultivated area; 60% of India's total cropped area is still rain-fed and therefore dependent on the monsoon. Changes in climatic variables such as rainfall can have an adverse impact on output and income, food prices and human health, and the food security. This study considers the combination of food crop choices as one of the ex-ante risk management strategies and examines farm households’ food crop portfolio choices as a response to climatic risk in semi-arid tropics of India. Unlike in other countries, intercropping and mixed cropping are prevalent among Indian farmers. Taking this into consideration and data from Indian farms findings show that farmers in semi-arid tropics of India are growing less risky food crop portfolio. Secondly, we find that in the presence of climatic risk, farmers tend to choose less risky crops and as a result less risky food crop portfolios. Finally, in the presence of climatic risk wealthy farmers and farmers with more cash on hand are more likely to choose relatively riskier food crop portfolio.

      In July 2013 FAO Lesotho began a pilot initiative called the Linking Food Security to Social Protection Programme (LFSSP). The programme's objective was to improve the food security of poor and vulnerable households by providing vegetable seeds and training on improved homestead gardening. The programme was intentionally provided to households eligible for a large-scale social cash transfer, the Child Grants Programme (CGP). In this paper we present findings from the impact evaluation of the two programmes. Overall we find positive effects of the programmes on homestead gardening and productive agricultural activities. Many of these observed outcomes appear driven by the combination of the two programmes. An additional year of CGP along with one year of the LFSSP achieved a number of outcomes which two years of receiving the CGP alone did not. This pilot has been used as the basis for the design of a national upscale response to El Nino drought in Lesotho including Home Gardening and Nutrition assistance for all CGP beneficiaries who were affected by a sharp increase of food prices.

      China's rapid increase in food imports has repercussions for China's and global resources. This study reviews the recent literature on China's virtual water and land trade through food trade, presents updated results for 2000–2015, and makes projections for 2030. The results show that the increased imports of virtual water and land have significantly eased pressure on these resources in China. Soybean imports have been the main contributor towards China's domestic savings of virtual water and land. China's food trade has increasingly contributed towards global savings of virtual water and land. Our projections suggest that the trend in savings of domestic and global virtual water and land will continue, with significant variations due to changes in resource use efficiency.

      Sustainable intensification (SI) is at the forefront of food security discussions as a means to meet the growing demand for agricultural production while conserving land and other resources. A broader definition of SI is emerging that takes into account the human condition, nutrition and social equity. Next steps require identification of indicators and associated metrics, to track progress, assess tradeoffs and identify synergies. Through a systematic, qualitative review of the literature we identified SI indicators, with a primary focus on African smallholder farming systems. We assessed indicators and metrics for which there is consensus, and those that remain contested. We conclude that, while numerous metrics for evaluating SI systems exist, many often-cited indicators lack strong sets of associated metrics.

      Despite of remarkable achievements in the past, China is also facing several major challenges, in particular on ensuring sustainable growth of agriculture, improving food security, increasing farmers' income. The paper reviews China's agricultural and food policy with specific focus on recent challenges, initial policy responses and their consequences, and re-adjusting in policies. The results show that the policy responses to the challenges of sustainable agriculture are strong and encouraging. Adjusting the national food security target in response to sustainable agriculture and major efforts to improve food security are significant. To increase farmer's income, China has shifted its policy regime from taxing to subsidizing and protecting agriculture in the past decade. However, the results of these efforts are mixture. Price interventions increased farmers' income, they also resulted in several serious problems. Good news is that some new efforts to solve these problems may bring China's market reform back to the right track though they still needs to be evaluated. The paper concludes that the previous experiences on agricultural development through institutional reform, technology change, market reform, and investment in agriculture should still be the keys for successfully ensuring food security and sustainable agriculture for China in the future.

      Gender inequality continues to constrain women's opportunities in the agricultural sector, both in terms of achieving food security and increasing agricultural productivity. However, investment in gender-responsive programming which promotes women's empowerment can help to overcome these constraints. This article discusses experiences in social protection programming design and implementation with respect to gender equality, food security and agricultural productivity: we find that while a large part of social protection programming remains focused on supporting women's domestic and care roles and responsibilities, there have also been important advances in thoughtful programming which supports more transformative changes in women's roles as producers. These types of programmes typically recognise the multiple risks and vulnerabilities that women face, both in their reproductive and productive roles, and aim to overcome these through integrated programming combining support for basic needs as well as broader empowerment goals.

      The phrase “biggest bang for a buck” is associated with the policy making question that governments and development agencies face: “Where and which crops should receive highest priority for improving local and global food supply'”. A first step of prioritisation is to identify region x crop combinations for which high impact can be anticipated. We developed a new method for this prioritisation exercise and applied it to data from the Global Yield Gap and Water Productivity Atlas (GYGA). Our prioritisation distinguishes between two policy objectives (humanitarian and economic) and builds upon the relative yield gap and climate risk. Results of the prioritisation are presented and visualised in Google Earth.

      The expansion of antipoverty transfers in low- and middle-income countries focuses on poverty reduction but it also raises important questions regarding their contribution to growth and development. The paper considers the role of design and context in programme outcomes. Distinguishing three main programmes types identified, the analysis relies on insights from theory and practice to identify rural context conditions capable of enhancing or undermining programme outcomes. It finds that context conditions are important and require careful consideration by programmers.

      Social protection programmes and agricultural interventions for family farmers tend to operate in isolation from each other. This paper shows how coherent targeting mechanisms can help to coordinate both policy areas and create synergies. We argue that target groups and targeting methods used in both areas are often very similar or potentially complementary, which constitutes a promising basis for better coordination. Moreover, the paper describes relevant cases to illustrate how targeting is already being used to foster synergies between the two areas. We conclude based on these case studies that targeting coordination and overall coherence are indispensable tools to generate positive synergies between social protection and agricultural interventions – a potential basis for addressing food security more effectively in the future.

           procurement and food assistance programmes

      This paper focuses on the rationale for supporting market interventions for smallholders through what we call Institutional Demand. Institutional Demand consists of different interventions that target procurement from smallholder farmers and distribute their surplus to vulnerable populations. This policy intervention links the goals of both agricultural development and social protection through three key areas: price stabilization; income generation and; food security. We argue that Institutional Demand should be a key policy intervention as it can directly address both rural poverty and malnutrition. It does this by linking the productive capacity of smallholder farmers with populations living in situations of food insecurity. Impact evaluations and assessments of Institutional Demand programmes are limited in scope and depth. Therefore, while this paper outlines much of the evidence thus far, the primary purpose of this paper is to push forward a new research agenda that looks at the ways in which Institutional Demand can promote policy synergies between the goals of social protection and agricultural development. The issues outlined in this paper present fruitful areas for more qualitative and quantitative assessments of Institutional Demand programmes.

  • Harnessing informal institutions to strengthen social protection for the
           rural poor

      Social protection has emerged as an effective policy response to tackle food insecurity, increase agricultural productivity and promote rural development across the developing world. Despite the proliferation of social protection programmes, their coverage is still low and informal support systems continue to be the key means of protection for the majority of the rural poor and vulnerable. Although their significance has remained largely invisible in policy and programming, there is growing interest to explore their potential and to support linkages with formal programmes. This article reviews the main types of informal social protection with their strengths and weaknesses, identifies their linkages to formal social protection, and proposes ways to strengthen them for more robust and inclusive social protection systems.

  • Developing approaches to achieve adequate nutrition among urban
           populations requires an understanding of urban development

      Since 2008 the world has become predominantly urban. By 2050, there will be 2.5 billion more people living in cities and most of these will be in small and medium-size cities in Africa and Asia. These continents are home to high malnutrition rates. Policy makers will need to ensure that food and nutrition security can be achieved by the growing urban populations, including the urban poor, in order for this urban growth to generate equitable economic growth. This paper demonstrates how understanding urban dynamics such as city size, urban infrastructures, and rural-urban linkages are critical for planning for adequate urban nutrition. In particular it highlights the potential strength of strategically investing in medium-size cities as they are more likely to generate equitable growth, including for their surrounding hinterlands, thus strengthening local foods systems and creating better enabling environments for improved urban nutrition through better sanitation infrastructures and increased access to nutritious foods by the urban poor.

  • Oil crops, aquaculture, and the rising role of demand: A fresh perspective
           on food security

      The global economy has experienced remarkable growth during the past twenty-five years. Rising incomes have helped to alleviate extreme poverty and calorie deficiencies worldwide, and have fueled demand for animal protein and processed foods. Income disparities have also widened, leaving the majority of the world's population in the lower income groups. This paper explores how economic growth, income distribution, and trade have influenced patterns of food demand and food security since 1990. It focuses on two of the most rapidly expanding segments of the world food economy, tropical oil crops and aquaculture. These commodity groups involve multinational companies and smallholder producers oriented mainly around global markets. To date, however, Sub-Saharan Africa has largely been by-passed by growth in both sectors.

  • Sustainable food security and nutrition: Demystifying conventional beliefs

      The global food system today faces the significant challenge of feeding more people amid dwindling natural resources and a more fragile natural environment. The path toward sustainable food security and nutrition is often riddled with inaccurate and oversimplified beliefs regarding the requirements and impacts of such a strategy. This includes the belief that trade-offs are inevitable when linking environmental sustainability with food security and nutrition strategies—which means that stakeholders have to prioritize one area at the expense of the other. Likewise, policymakers and researchers alike often make inaccurate assumptions about technological innovations, gender, biofuels, and smallholder farming. Such sustainable food security and nutrition “myths” pose a significant challenge to the effective design and promotion of more environmentally-friendly agricultural and food systems. This paper will explore the myths and realities surrounding the relationship between environmental sustainability, food security, and nutrition. It will focus on debunking some of the common myths that hamper sustainable food security and nutrition efforts and will highlight actions that can mutually reinforce food security, nutrition, and environmental sustainability. Providing the world's growing population with a more secure and sustainable supply of nutritious food is possible but not automatic and requires an accurate and comprehensive understanding of the dynamics surrounding sustainable food security and nutrition pathways.

  • Growing advantage of large farms in Asia and its implications for global
           food security

      When the wage rate is low, a labour-intensive production method is chosen. Since it is costly to monitor hired labourers in agriculture, small-scale farms dependent on family labour are more efficient than large farms relying on hired labour. This leads to the inverse relationship between farm size and productivity, if land markets do not reallocate land. When the wage rate increases, labour-saving and machine-using production methods become efficient. If machinery and land are complementary and machines are indivisible to some extent, large-scale mechanized farms become more efficient, which tends to weaken the inverse farm size-productivity relationship. This article argues that if small-scale farms continue to dominate in the face of the increasing wage rate in Asia, many countries in this region will lose their comparative advantage in agriculture.
