The main causes of water scarcity in Africa are physical and economic water scarcity, rapid population growth, and the effects of climate change on the water cycle. Water scarcity is the lack of fresh water resources to meet the standard water demand . [ 127 ]
The human-caused changes to the water cycle will increase hydrologic variability and therefore have a profound impact on the water sector and investment decisions. [9] They will affect water availability (water resources), water supply, water demand, water security and water allocation at regional, basin, and local levels. [9]
Sand and water on the side of the road, causing erosion on the environment Plastic bags dumped by the road side in Katete in mbarara district in western Uganda. The erosion caused by rains, rivers and winds as well as over-use of soils for agriculture and low use of manures have resulted in turning the soils infertile, as for example, in the plains of the Nile and the Orange River.
Water consumption has proven to be very detrimental to the environment and its ecosystems, leading to water depletion and water scarcity. Not only do these affect marine organisms, but also human's food sources, such as crops. [305] The industry is culpable for roughly one-fifth of all industrial water pollution. [306]
As such, water scarcity is caused by a mismatch between when and where people need water, and when and where it is available. [11] One of the main causes of the increase in global water demand is the increase in the number of people that has resulted in the human overpopulation driving climate change, mass species extinction and many of not ...
Water scarcity poses a threat to ecosystems and biodiversity, primarily through its impact on aquatic habitats, rivers, wetlands, and lakes. [3] Decreased water flows and the drying of water bodies disrupt the delicate balance of ecosystems, affecting a range of species including fish, amphibians, and water-dependent plants, experience habitat loss and fragmentation, affecting their ...
