Many existing water-sharing treaties should be re-assessed in the context of climate change, write Shlomi Dinar, David Katz, Lucia De Stefano, and Brian Blakespoor in a World Bank working paper.

In March, the Intergovernmental Panel on Climate Change released its latest comprehensive synthesis of climate change research. The report concludes that “impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability.”

Despite the threat posed by flooding and sea-level rise, relatively little attention has been paid to the potential for environmentally induced instability in coastal West African cities. However, current trends, including rapid population growth, land use patterns, and increasing climate impacts, suggest the costs of inaction in these urban areas are rising.

These practices have left a wound that continues to fester as the human population swells.
