Climate Change
Climate change is an on going topic of discussion , and the 2015 United Nations Climate Change Conference in Paris is soon approaching . Africa is no exception to this and the effects of climate change seem to be more severe for Africa when compared to the rest of the world.
The paper by Marisa Goulden , Declan Conway and Aurelie Persechino entitled , ' Adaption to climate change in international river basins in Africa, discusses the current knowledge we have of the potential impacts of climate change on water resources in Africa and the possible limits, barriers or opportunities for adaption to climate change in internationally shared river basins.
Management of the potential affects is also further challenged by the transboundary nature of river basins .
The paper uses a climate model that projects warmer conditions ranging from +3.2celcius (East Africa), +3.6 (Sahara) by 2080. Nearly all models project wetter conditions in West and East Africa , and drier conditions in southern Africa and Sahara.
To adapt to climate change the paper discusses looking at a supply and demand side . The suuply side adaptions that are mentioned are; exploiting groundwater, increasing storage in reservoirs , desalination of seawater, rainwater harvesting and water transfers between river basins.(Kundzeqwicz et al 2007)
The demand side adaptions include improvement of water use efficiency and recycling of water, reduction of demand for irrigation by changing crops or cultivation practices, reduction of demand by importing agricultural products, sustainable water use practices, use of water markets to re allocate water between uses, and use of economic incentives such as metering an pricing.(Kundzeqwicz et al 2007)
