What are some environmental problems in Niger?

in Niger, 80 percent of its land is covered by the Sahara desert and sand, making niger more dangerous then most countries. Also the Islamic population in southern and western is clusterd with just over 15,000,000 people, thus, making it a very crowded country. And Niger constantly has one of the lowest ranks of the United Nations' human development index. One more thing, Niger remains handicapped by its landlocked position, desert terrain, poor education and poverty of its people, lack of infrastructure, poor health care, and envirometal degradation. i hope you learned something here.
