The Future of Dryland Cereals and Legumes in South Asia and Sub-Saharan Africa: Climate resilient crops for food security
90 million hectares of South Asia and Sub-Saharan Africa is dryland. These regions also experience acute poverty, and crop success is vital for survival. For smallholders, climate change threatens cereal and legume production, and thus both livelihoods and food security in these regions. Several crop-specific studies indicate a significant decline…
The Future of Wheat: Could climate-resilience genes be the key to safeguarding the world’s most cultivated crop?
Wheat is the most widely cultivated crop in the world. It makes up a whopping 20% of global calorie and protein intake. At the same time, future predictions about this grain on which we so depend are worrisome. Not only is demand expected to eclipse current wheat production, but climate…
Biophysical and economic implications for agriculture of +1.5° and +2.0°C global warming using AgMIP Coordinated Global and Regional Assessments
This study presents results of the Agricultural Model Intercomparison and Improvement Project (AgMIP) Coordinated Global and Regional Assessments (CGRA) of +1.5° and +2.0°C global warming above pre-industrial conditions. This first CGRA application provides multi-discipline, multi-scale, and multi-model perspectives to elucidate major challenges for the agricultural sector caused by direct biophysical…

Rural transformation and the future of cereal-based agri-food systems
Rural transformation is an inevitable and fundamental process of development. However, the speed and dimensions of rural transformation can affect investments in major staples such as maize, wheat and rice, which continue to play an important role in agri-food systems around the globe. This paper investigates the impacts of rural…
Climate change and eastern Africa: a review of impact on major crops
Global warming has become one of the major challenges in maintaining global food security. This paper reviews the impacts of climate change on fourteen strategic crops for eight sub-Saharan Africa countries. Climate change is projected to increase median temperature by 1.4–5.5°C and median precipitation by −2% to 20% by the…
Assessing climate adaptation options for cereal-based systems in the eastern Indo-Gangetic Plains, South Asia
Abstract New farming systems and management options are needed in South Asia as the intensive rice–wheat production system is set to become increasingly unsustainable under climate change. In the current study, six cropping systems options/treatments varying in tillage, crop establishment method, residue management, crop sequence and fertilizer and water…
Can sub-Saharan Africa feed itself?
Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub-Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current…
Impact of Climate Change, Weather Extremes, and Price Risk on Global Food Supply
Can Ethiopia feed itself by 2050? Estimating cereal self-sufficiency to 2050
Producing adequate food to meet global demand by 2050 is widely recognized as a major challenge, particularly for sub-Saharan Africa (SSA) (Godfray et al. 2010; Alexandratos and Bruinsma 2012; van Ittersum et al. 2016). Increased price volatility of major food crops (Koning et al. 2008; Lagi et al. 2011), an…
