Top 5 Best Uses Of Water In Sub-Saharan Africa

drink more water to re-hydrate

The human body uses more than 100 different kinds of water for different purposes. If you think about it, a lot of water gets lost in our daily activities like breathing and drinking. In the process of respiration, digestion, etc, human body naturally loses water contents in the sweat. So, it’s very much significant to drink more water to re-hydrate.

Now let’s see some more uses of water for industrial applications. Water has been used for centuries in industrial applications. One of the most common uses of water is in the manufacturing industry. For example, in the textile industry, cotton fiber fabric is made by using water in the detergents. And in the electronics industry, electronic fluids like semiconductor dyes are made by water before they get prepared for use. The wastewater treatment plant in our city generates a large amount of wastewater for these purposes.

Agriculture is the third largest user of freshwater withdrawals

These days, freshwater withdrawals are increasing across sub-saharan Africa as a result of insufficient rainfall. In addition, some countries in the region have experienced substantial declines in freshwater withdrawals due to drought. This has encouraged the use of industrial salts for treating water withdrawals from groundwater.

Irrigation systems in some countries in sub-Sahara are also using industrial salts as one of the solution to meet their water needs. Most of the countries across sub-Sahara suffer from lack of availability of surface water. So, the major users of groundwater are Egypt, Iraq, Saudi Arabia and Algeria. They are the largest user of groundwater and the largest exporter of freshwater.

Irrigation systems are not efficient enough to irrigate most of the arable lands in the Middle East. So, agriculture relies heavily on groundwater to meet their needs. During droughts, crops become dry and yield less.

So, this is the major reason why they use less than the required water in relation to the demand. What’s more, when we talk about agricultural production and growth rate, there is a marked difference in the two. Across the south asia, there is a much lower rate of growth than in north-east Asia. It’s clear that the imbalance is largely because of water constraints in the north-east Asia.

farming requires large amounts of freshwater

The recent decades have also seen a serious degradation in water quality across the sub-Saharan Africa. This has been facilitated by the use of irrigation and hydropower projects. There has been a rapid expansion of agriculture in the region, especially in the past few decades. This has made it a net importer of freshwater, as farming requires large amounts of freshwater to support intensive agricultural growth.

Irrigation and hydropower projects have been a blessing in this regard, as they have helped to bring down agricultural production cost and improve water quality across the sub-Saharan Africa. They have reduced the water withdrawals, which have led to less water loss, evaporation and groundwater contamination. With these projects, farmers have been able to increase their profitability. However, these projects cannot be sustained for long, as the population grows, the number of people living in each Agricultural Area increases, and the pressures on the environment from industry, population growth and population will continue to rise.
