Mohammad Ponir Hossain/ReutersFarmers in Bangladesh are learning to grow crops in increasingly salty soil. Salt intrusion is a growing problem, driven by a combination of climate change, poor water management, and shrimp farming. It means much of the country’s coastal farmland is unusable in the dry season as saltwater evaporates. The government and foreign NGOs are providing farmers with salt-resistant crops, salinity meters, and rainwater irrigation systems, and are training them to minimize evaporation that increases salinity. As a result, according to one analysis, the amount of high-salinity land used for farming in the dry season has gone up 270% since 2016. Bangladeshi farmers have overcome many challenges, Context noted: Rice production has more than tripled since 1970. |
