South African President Jacob Zuma has pointed out that more industrialized nations are largely responsible for climate change, yet poorer countries often suffer from it the most. "We face the real threat of reduced water availability resulting in low crop yield, food insecurity, disease prevalence and tension between different sectors within communities," he said recently at the 29th annual South African Development Community summit.
