Abstract:
The impacts of changing climate on water resources may be exacerbated when they occur in areas with already scarce water supplies, experiencing frequent droughts, and disparities between water requirements and convenience. Wherefore, water resources in Sub-Sahara Africa will and is been negatively wedged by changes in climate, conferring to current climate change models by Intergovernmental Panel on Climate Change. These models predict the effects in Africa and other regions of the world, including Latin America. A further 10% decrease in rainfall is anticipated in Sub-Saharan Africa by 2050, which will result in a 17% decrease in surface water and subsurface water bodies. Population growth has increased the demand for food and fresh water for domestic and industrial use; however, the majority of freshwater resources have already been depleted, and agricultural productivity has decreased globally, especially in Sub-Sahara Africa. In dry and semi-arid states, a global decline in crop yields, or agricultural productivity, results in food shortages and a sharp rise in food price inflation. Water shortage has worsened due to the changing climate and climatic variations in most parts of the world, which directly and indirectly affect human and animal health. This brief study highlights how climate change has an impact on water scarcity and other related issues.
