A farmer gathers the remains of a dying corn plantation in Chiang Saen district along the bank of the Mekong River. Water levels of the mighty Mekong River have dropped drastically due to drought-like conditions and damming upstream. The drop disrupts the region’s water supply, transport routes, and the livelihood of communities in Thailand, Laos, Cambodia and Vietnam. The UN Intergovernmental Panel on Climate Change (IPCC) predicts that more than one billion people will face water shortages due to climate change.
