Maize is grown by millions of smallholder farmers in South Asia (SA) under diverse environments. The crop is grown in different seasons in a year with varying exposure to weather extremes, including high temperatures at critical growth stages which are expected to increase with climate change. This study assesses the impact of current and future heat stress on maize and the benefit of heat-tolerant varieties in SA. Annual mean maximum temperatures may increase by 1.4–1.8 °C in 2030 and 2.1–2.6 °C in 2050, with large monthly, seasonal, and spatial variations across SA.
Social Protection Programs for Africa’s Drylands explores the role of social protection in promoting the well-being and prosperity of people living in dryland regions of Sub-Saharan Africa, with a specific focus on the Sahel and the Horn of Africa.
India is one of the world's largest food producers, making the sustainability of its agricultural system of global significance. Groundwater irrigation underpins India's agriculture, currently boosting crop production by enough to feed 170 million people. Groundwater overexploitation has led to drastic declines in groundwater levels, threatening to push this vital resource out of reach for millions of small-scale farmers who are the backbone of India's food security.
Water resources management is an important part in farming system development. Agriculture in Chittagong Hill Tracts of Bangladesh is predominantly rainfed with an average 2210 mm monsoonal rain, but rainfall during dry winter period (December–February) is inadequate for winter crop production. The natural soil water content (as low as 7 %) of hillslope and hilltop during the dry season is not suitable for shallow-rooted crop cultivation. A study was conducted to investigate the potential of monsoonal rainwater harvesting and its impact on local cropping system development.
Human activities are increasingly leading to overuse of surface water and nonrenewable groundwater, challenging the capacity of water resources to ensure food security and continuous growth of the economy. Adaptation policies targeting specifically water security can easily overlook its interaction with other sustainability metrics and unanticipated local responses to the larger-scale policy interventions.
Tubers, pulses and millets are important for the livelihoods and nutrition of poor farmers, especially in fragile regions. These crops are not only underutilised, but are also underresearched. Ama Sangathan, a women federation consisting of 1200 indigenous women, have revived these crops in two blocks in Odisha, by their vibrant campaigning.
This book focuses on the medium-term prospects (over the next two decades) for increasing the resilience to drought and other shocks of people living in dryland areas of East and West Africa.
Drylands make up about 43 percent of the region’s land surface, account for about 75 percent of the area used for agriculture, and are home to about 50 percent of the population, including many poor. Involving complex interactions among many factors, vulnerability in drylands is rising, jeopardizing the livelihood for of millions.
Indian agriculture is once again in a slowdown. After the spurt of 2004–05—2011–12 when growth accelerated and the variability of production declined, in recent years growth has slowed and volatility has risen. Given weak world economic prospects and looming climate change, the main objectives of agricultural policy should now be to (i) enhance effi ciency of production and natural resource use, and (ii) devise appropriate safety nets to cope with risks whether from markets or climate.
As planetary boundaries are rapidly being approached, humanity has little room for additional expansion and conventional intensification of agriculture, while a growing world population further spreads the food gap. Ample evidence exists that improved on-farm water management can close water-related yield gaps to a considerable degree, but its global significance remains unclear.
