Just found a great youtube video on much of what my “Agroforestry in Arid Environments” review paper is about. It is done really well and describes desertification, greening projects in Africa, China, Mongolia, and Saudi Arabia, sand drift, agriculture, etc. North America is not represented here, but this video gives a nice view on projects going on worldwide.
If this subject interests you, please read my blogpost containing the review paper I wrote a month ago on much of the issues discussed in the video. My review paper focuses on the United States Southwestern desert areas and the unique possibilities and challenges that region faces, however worldwide efforts are also discussed. Enjoy!
