"You don't have to be a source of emissions to be affected," noted Adel Hanna, a climate modeling expert at the Institute for the Environment at the University of North Carolina at Chapel Hill. "That's why we call it a global effect." Hanna said that the two biggest climate worries for North Africa – water scarcity and higher temperatures – are feeding off each other, with limited rainfall rapidly evaporating from the soil in higher temperatures. "The net effect is the loss of water resources," Hanna said – something that affects all forms of agriculture, including grazing for livestock.
Around the region, herders are searching for water by digging new and deeper wells to reach aquifers. Some share water with neighboring landowners by taking turns using a common well.
"But by no means will this replace the need for better policy or support from government, and actually the global community, in addressing issues related to climate change," Hanna said.
