The global demand for staple crop products is expected to grow by 60% between 2010 and 2050 mainly as a result of increased population, per capita income growth and use of biofuels (Alexandratos and Bruinsma, 2012). This is also the case for rice, which provides 20% of the world’s food energy (Fischer et al., 2014). Global demand for rice will continue to increase from 479 million tons in 2014/15 to 551 million tons in 2029/30 (GRiSP, 2016). To meet this estimated future demand, agricultural production must be enhanced in an environmentally sustainable manner in the context of increasing competition for water, land and labour, as well as the constantly evolving threat from abiotic and biotic stresses, and under potentially more extreme weather conditions associated with climate change. Agriculture also needs to address problems of poor food and nutrition security for smallholder rice farmers, including women farmers, in Asia, Latin America and sub-Saharan Africa.
