Africa’s trade under a changing climate

The devastating effects of climate change are already being felt across the planet, including in Africa. The 2011 drought-induced famine in the Horn of Africa affected more than 10 million people, claimed 257,000 lives and cost over $1 billion in damages. The recent Africa Adaptation Gap Report by the UN Environment Programme warns that climate change could reduce total crop yields in sub-Saharan Africa by as much as 20% by 2070. Worse still, it could begin to affect Africa’s trade potential. For example, a projected sea-level rise in Tanzania of 70 centimetres by 2070 could devastate the port city of Dar es Salaam, its largest and richest city and a major player in East Africa trade, and cost the country about $10 billion in property damages and related losses. Environmentalists warn that rising sea levels could cause severe flooding, submerge land and destroy coastal ecosystems.
