Megadrought in Chile

Drought is a massive problem for Chile. Jane Chambers has been living in the capital Santiago for more than ten years and has seen huge changes in that time. It used to rain frequently in the winter months between June and September and the Andes Mountains which run down the whole of Chile were snow-capped all year round. But that doesn’t happen anymore. Jane reports on the impact of the mega drought on the country and what is being done about it. She talks to climate scientists Sebastian Vicuna, Director of the Global Change Research Centre, at the Catholic University of Chile and to Rene Garreaud, a Professor in the Geophysics Department at University of Chile and Deputy Director of the Center for Climate and Resilience Research, about whether the megadrought is the result of natural weather patterns or of climate change. She meets farmers who are struggling to find pasture for their goats in the village of Til Til, and Francisco Meza, a Professor in the department of agriculture and forestry at the Catholic University in Santiago, who is helping agriculture adapt to low rainfall. And Jane hears about ways to increase the availability of drinking water through small-scale desalination and by capturing moisture from the air.
