Your nation is also involved in fighting desertification at its cause: the Typha infestations in Lake Chad and your rivers, with recent successes in Jigawa. Typha is a dessication machine. Each river or lake cleaned is a blow against the desert. To continue the never-ending struggle against the weed requires a profit- which is available in food and fuel. Typha is a top-rank ethanol crop, and when grown in clean water, a very productive food plant. Fight the dryness in your wetlands.
