Simple steps to climate-proof farms have big potential upside for tropical farmers

Cacao farmers in Nicaragua lose their crop, the main ingredient for chocolate, to fungal blight and degrading soils. Yields drop in Vietnam’s rice paddies because of higher temperatures and increased salinity. Bean and maize growers in Uganda see their plants die during severe dry spells during what should be the rainy season. The two-punch combination of climate change and poor agricultural land management can be countered with simple measures that keep farms productive and profitable. Implementation of these climate-smart agriculture (CSA) practices can increase yields, benefit the environment and increase farmer income, according to a new cost-benefit analysis by the International Center for Tropical Agriculture (CIAT) published November 19 in PLOS ONE.
