NASA is offering its earth-observing satellites to help nations in Africa manage crop production as well as natural disasters. The program is initially focused on the Sahel region in West Africa. The Sahel is one of the most vulnerable regions in the world to climate change, where rising temperatures and increasingly erratic rainfall are wreaking havoc on farmers, disrupting food production, and fuelling widespread hunger and malnutrition. The whole livelihood along the Sahel depends on a few main crops, like millet and sorghum, that are highly dependent on rainfall. NASA data can improve food security through better forecasting.
