In the 1979–1983 CE drought in northeast Brazil, hundreds of thousands of people died (Arons 2004). The northeast region consists of 18% of Brazil’s land and approximately one-third of Brazil’s total population. In northeast Brazil, 58% of the people live on less than US$2 per day (Garmany 2011). There is a long history of multiyear to decadal droughts in this region, causing large-scale deaths, starvation and malnutrition, and widespread socioeconomic and political strife. These recurring droughts, as well as wet periods, exacerbate class differences among the people of the region and make severe adverse impacts on agriculture (Arons 2004).
