From the areal photograph one can clearly see that life evolve around the Nile river. The river provides its people with the precious resource of water that not only is used for transport,but for agriculture and life sustaining drinking water. [...] South African cities need to prepare for rapidly increasing oil prices,unpredictable rainfall patterns and fresh water demand [...] Economic accounting for water –EAW –is a process of systematically measuring the contribution of water to the economy [...] All three depend on an equitable share of quality water from the Okavango River,the fourth largest in Africa [...] CAPE TOWN has in the past year experienced one of its worst rainfall figures in almost 90 years,and a sustained drought could deplete the region’s fresh water supply. [...] Cities at risk of water restictions and water outages,like Durban,Cape Town and many more,are encouraged to harvest rainwater and recycling greywater. [...] As aging infrastructure and a wasteful attitude are to blame for much of the Cities water concerns it is still surprising that the city is still not trying to tackle the issue of water and sanitation at the cause of the problem. [...] Nel says these rising temperatures will have many consequences,including greater reliance on underground water,which will increase energy use. [...] All SA’s coal-fired power stations require significant amounts of water. A 5000MW plant (about the size of Medupi) will use 60m m³ of water every year with wet cooling (that’s 2000l a second),but only 6m m ³ with dry cooling technology. [...] it can take centuries,or even millennia,for groundwater levels to be replenished naturally. The Great Artesian Basin in Australia has water that is two million years old! [...] | ||
