Okay so northern Africa and the Sahara desert is the best example of desertification.
2 ways humans have contributed to that is: 1) pastoral nomadism 2) little to no settlements to increase water supply
how it impacted the environment: so now the environment there is sandy, only organisms adapted for those extreme environment can live there ex. camel, cactus, etc.,
how it impacted quality of life: quality of life diminished, not enough water to sufficiently feed the populations, people live in extreme poverty, people are moving away, and the climate is very dry and hot, pretty much not a place anyone would want to live
