Chile, Argentina and the American West are in the midst of a decade-long, megadrought – the driest conditions those regions have seen in a century. And many areas in Western Canada and the United States are experiencing extreme drought – a once in 20-year event. Drought makes agriculture less productive, reduces crop yields and increases heat-related deaths. It adds to conflict and migration, as marginalized people are dispossessed of their land. In short, it leaves people more vulnerable.
