Food insecurity is a serious impact of climate change in a region where 10% of the GDP depends on agriculture, livestock and fisheries  . Crop losses largely result from highly variable rainfall and seasonal droughts, which have increased significantly in recent decades  , particularly the observed changes in the MSD that reduces rainfall at the onset of the rainy season  . Small and subsistence farmers experience the highest impact because they practice rainfed agriculture , along with poor neighbourhoods, which face socioeconomic and physical barriers for adapting to climate change . In 2015, precipitation diminished between 50% and 70% of its historic average, causing a loss of up to 80% of beans and 60% of maize, leaving 2.5 million people food insecure, 1.6 million of whom were in the Dry Corridor of CA . In 2019, the region entered its fifth consecutive drought year, with 1.4 million people in need of food aid. Seasonal-scale droughts are projected to lengthen by 12-30%, intensify by 17-42% and increase in frequency by 21-42% in RCP4.5 and RCP8.5 scenarios by the end of the century .
