Once the home of the Hamoun wetlands, an 800-square-mile (2,000-square-km) oasis fed by the Helmand River, has now become one of the driest in the world. But until the 90s, the area was booming in agriculture and full of flora fauna. Located in southern Afghanistan, the Sistan Basin has been consistently dammed and used for irrigation for decades. That, coupled with one of the most severe droughts registered in the area ever, has turned the once thriving wetlands into a dust bowl. Precipitation has dropped 78%, and efforts by the United Nations to remedy the situation have been hampered by the war.
