Climate change, agriculture, and potential crop yields in Central Asia
Agriculture in Central Asia is vulnerable to climate change due to rising aridity, declining availability of water resources for irrigation, and low adaptive capacity. We use climate data from CMIP5 with RCP8.5 for greenhouse gas emissions and the DSSAT crop model to investigate how yields of key crops in Central Asia will be affected by climate change. We distinguish changes in yields between spring and winter plantings, between irrigated and rainfed crops, and between crops grown with high and low amounts of fertilizer. The results suggest that countries (and areas within countries) that either have moderate summers or grow a number of crops in a relatively cold winter will benefit from climate change, while countries that grow many of the crops in the summer will experience losses.
Agriculture–nutrition linkages in Tajikistan: Evidence from household survey data
In Tajikistan, the poorest country in the Central Asia region and one of the poorest in the world, food consumption patterns remain inadequate for a significant share of the population. Undernutrition and child stunting, among other outcomes, remain prevalent. At the same time, overnutrition and obesity are becoming increasingly serious. Using pooled cross-section datasets collected in 2007 and 2015 from farm households in Khatlon province (the major agricultural area in Tajikistan), we investigate how key agricultural production practices (APPs) (household-level production diversification, land productivity, and production scale) are associated with household-level and individual-level nutr...
Agriculture-nutrition linkages, cooking-time, intra-household equality among women and children: Evidence from Tajikistan
Household-level agriculture-nutrition linkage (ANL) tends to be strong in a rural subsistence setting with limited access to the food market. In such a context, markets for food processing services also may be imperfect, and consequently a household’s time-investments in cooking may become important. Using the primary data in Tajikistan, we show that longer periods of time dedicated to cooking by women in the household often significantly enhance household-level ANL. Furthermore, an increase in the diversity, scale, and efficiency of household production, as well as longer cooking time, can also reduce intrahousehold inequality in nutritional outcomes among women and children. These effects are stronger in areas with lower nighttime light intensity and for households with lower values of cooking assets. In a context where household-level ANL is strong, ANL may also depend on households’ self-production of complementary inputs, including cooking services. This dependence reveals both unique opportunities for and vulnerabilities of ANL for the rural poor.
2019 Global food policy report
IFPRI’s flagship report reviews the major food policy issues, developments, and decisions of 2018, and considers challenges and opportunities for 2019. This year’s Global Food Policy Report highlights the urgency of rural revitalization to address a growing crisis in rural areas. Rural people around the world continue to struggle with food insecurity, persistent poverty and inequality, and environmental degradation. Policies, institutions, and investments that take advantage of new opportunities and technologies, increase access to basic services, create more and better rural jobs, foster gender equality, and restore the environment can make rural areas vibrant and healthy places to live and work. Drawing on recent findings, IFPRI researchers and other distinguished food policy experts consider critical aspects of rural revitalization.
2021 Global food policy report: Transforming food systems after COVID-19
The coronavirus pandemic has upended local, national, and global food systems, and put the Sustainable Development Goals further out of reach. But lessons from the world’s response to the pandemic can help address future shocks and contribute to food system change. In the 2021 Global Food Policy Report, IFPRI researchers and other food policy experts explore the impacts of the pandemic and government policy responses, particularly for the poor and disadvantaged, and consider what this means for transforming our food systems to be healthy, resilient, efficient, sustainable, and inclusive. Chapters in the report look at balancing health and economic policies, promoting healthy diets and nutr...
2018 Global food policy report
IFPRI's flagship report reviews the major food policy issues, developments, and decisions of 2017, and highlights challenges and opportunities for 2018 at the global and regional levels. This year's report looks at the impacts of greater global integration—including the movement of goods, investment, people, and knowledge—and the threat of current antiglobalization pressures. Drawing on recent research, IFPRI researchers and other distinguished food policy experts consider a range of timely topics: ■ How can the global food system deliver food security for all in the face of the radical changes taking place today? ■ What is the role of trade in improving food security, nutrition, and...
New modalities for managing drought risk in rainfed agriculture
In this paper we explore the potential for a new approach to managing drought risk among rainfed rice producers in Odisha, India. Droughts have historically been a serious constraint to agricultural production in rainfed agricultural systems, with droughts resulting in significant reductions in both yields and cultivated area, in turn leading to significant impacts on rural livelihoods and food security. Scientists and policy makers have proposed various strategies for managing risks, with limited success. In this study we consider two such strategies, specifically drought-tolerant rice and weather index insurance. While neither drought-tolerant cultivars nor weather index insurance products...
Valuing Crop Biodiversity
This book examines the challenges faced by farmers trying to maintain crop biodiversity in developing and transitional economies. Using a collection of empirical case studies of farmers and crop scientists across a range of agricultural economies and income levels, it presents economic tools and methods for valuing and managing crop biodiversity. It discusses the economic benefits of crop biodiversity for farmers and suggests ways in which crop biodiversity can be supported by national policies. The book provides an indispensable 'tool kit' for all those concerned with the development of strategies to facilitate sustainable management and conservation of crop genetic diversity for future generations.
Using zero tillage to ameliorate yield losses from weather shocks
Zero tillage (ZT) for wheat is one of the most widely adopted resource-conserving technologies in the rice-wheat systems in northern India. In areas of Haryana with rice-wheat systems, 36.5 percent of all farmers practice ZT on 35 percent of their wheat area. Yet the literature measuring the impact of ZT on farmers’ fields is scarce. This study fills this gap by using the data collected from a random sample of 717 farmers from 50 villages in 10 districts of Haryana. It applies the difference-in-differences method to five-year recall data on wheat yields in ZT and conventionally tilled plots of land to quantify the crop loss due to unseasonal rains right before wheat harvests in March 2015....
2020 Global food policy report: Building inclusive food systems: Synopsis
Food systems are at a critical juncture—they are evolving quickly to meet growing and changing demand but are not serving everyone’s needs. Building more inclusive food systems can bring a wide range of economic and development benefits to all people, especially the poor and disadvantaged. IFPRI’s 2020 Global Food Policy Report examines the policies and investments and the growing range of tools and technologies that can promote inclusion. Chapters examine the imperative of inclusion, challenges faced by smallholders, youth, women, and conflict-affected people, and the opportunities offered by expanding agrifood value chains and national food system transformations. Critical questions ...
