Precipitation in Bolivia has become unpredictable - rainfall is heavier but shorter than it once was. That leads to periods of both flooding and drought, posing major challenges for rural regions where farmers are losing their entire harvests. Now, an initiative to improve the country’s water management and irrigation systems is aiming at helping farmers adapt to the challenges of climate change. A pilot project in the Andes has helped set up a network of water tanks, canals and a reservoir, and it has also spurred the planting of new trees. A film by Michael Altenhenne.
