The Global Rundown
Food security is suffering in Africa’s Lake Chad Basin due to a confluence of conflict, drought, and declining water levels, according to the Food and Agriculture Organization of the United Nations. A report suggests that concerns about water could soon prompt Argentina, Chile, and other Latin American countries to enact stricter environmental regulations for mining. California farmers south of the Sacramento-San Joaquin Delta are set to get their full water allotments for the first time in a decade. Leaky water infrastructure is compounding a severe drought in Cuba. Water disparities between the northern and southern United States could one day lead to diversions from the Great Lakes, a NASA scientist predicts. Flooding from Cyclone Debbie exacerbated erosion in Australian river basins that contribute large amounts of sediment to the Great Barrier Reef.
“Because there’s so much fresh water, you can imagine that 50 years from now…there might actually be a pipeline that brings water from the Great Lakes to Phoenix. I think that’s part of our future.” –Jay Famiglietti, senior water scientist at NASA’s Jet Propulsion Laboratory, speaking about potential future diversions of Great Lakes water to address water disparity in the United States.

In context: Buckled canals, damaged because of groundwater pumping, impair California’s ability to deliver water and control floods.

Science, Studies, And Reports
Argentina, Chile, and countries in Central America could all enact stricter water regulations for mining companies in the future, according to a report by London-based BMI Research. “When the negative externalities of gold mining, namely mercury and cyanide exposure to water sources, are left unaddressed, public opinion on all mining activity can motivate extreme legislation,” the report said. Just last month, El Salvador voted to ban all metal mining due to water concerns. MINING.com
On The Radar
The Lake Chad Basin is in the midst of a humanitarian and ecological crisis, according to the director-general of the United Nations’ Food and Agriculture Organization. Violent conflict, droughts, and declining water levels in Lake Chad have all taken a toll on the region’s food security. FAO
