Introduction Water is a very vital resource for men and the whole world at large, the truth behind the most common saying water is life. Water or the lack thereof has built and destroyed nations and it is very important therefore to study analyze and comprehend this very important resource. When looking into this resource it is important to look at it as any other form of energy, it is as important or even more important. The there also has to be then the consideration of the quantity available. The quantity available has to be studied with respect to the demand of the same resource. The form in which it is availed must also be noted. Water can be either in form of precipitation, in forms of surface water like rivers, lakes, and dams. It may also be in form of underground water in which case wells have to be sunk so as to access it.I am going to look into the water footprint in Sudan. Sudan was a single country up until the year 2011 when it split into two countries the South Sudan and North Sudan. It is a country in Eastern Africa, on the Northern side just below Egypt. It borders The red sea to the east and extends the Sahara desert on the western side. The river Nile which is the longest river in Africa goes right across it, in fact, the two main tributaries to river NileThe Blue Nile and the while Nile join in south Sudan before streaming down to the Mediterranean sea through Egypt. Because of its position in latitude, it is a tropical country and its climate ranges from being hyper-arid on the north and wet-and-dry to the south-west. The temperatures recorded in Sudan do not vary as much but however what varies is the length of the rains during the rainy season and the length of the dry seasons. Sudan has a tropical sub-continental climate that has been over the study from the last 20 years. The climate extends from the desert climate in the north part of the country, through a belt of summer-rain climate to semi-dry climate conditions. The recorded of average annual rainfall show the rain to be at 250 mm, but with ranges that vary from 25 mm in the dry northern parts to 700 mm in the southern parts. The country has not had a history of having sufficient rainfall. With the current United Nations predictions that the water use is bound to increase to close to twice the normal usage, it is alarming for these nation. This should raise awareness for people to start using water sustainably with practices such as recycling being emphasized. The historic trend in water consumptionIn Sudan, like many other countries, agriculture has been the main consumer of the water. Historically, there were many cultivated areas that have since shrunk due to climate change.The water consumption rate in Sudan was low in the past but however, the consumption has been on the rise. The rise in consumption can first be attributed to the increased population. The population has risen from 28 million in 2000 to an estimated 42.1 million in 2017. Every new child has his own contribution to the water footprint of the country and with a population increase of close to 14 million, an equal increase demand is expected. That is a 50 percent increase in demand for water without the same increase in water availability. This means that there is currently an increased pressure on the available water points for water. There are many settlements along the river Nile, the Blue Nile, and the White Nile. These settlements were here due to the ready supply of water from the rivers. This enabled them to plant crops and be able to irrigate then whenever there was a lack of water. Water footprint by consumptionThe water footprint is the amount of water that is consumed by human activity as well as other activities that use up the available water. The main user of waters as seen in Sudan is the domestic use of water this includes; drinking water, water used for bathing, water used for cleaning, and water used for other domestic purposed. The agricultural use is the highest consumer of water in Sudan. Being a dry region pre-dominantly, there is a need in many areas to substitute the water available to plants by precipitation with water from other sources through irrigation, This however much of a consumer it is has been necessitated by the need for food in plenty. Industrial use is the other consumer of water. Water in industries has also been on demand thereby increasing pressure on the water sources that are already scarce as it is. Industries are the source of almost everything used in the day to day life. Farm products processing industries are also considered as an industry on its own. Industries require water so as to clean the industries, used in cooling of machines and also used as a component in production in itself. Unlike other uses however industries mostly pollute the water after use as others dump their wasted in the rivers, while some wait for rain and allow the consequent flow to carry their waste. Industries have the record of contaminating water sources and they should now change their practices so as to reduce the water footprint due to the increased pressure. Water once polluted requires a rigorous process of decontamination and recycling so as to make it reusable. Sudan is known for producing crude oil. Oil is a very hard contaminant to remove. Once it has entered the water, it is very hard to separate it from the water. A very expensive process like evaporation is needed to do so. It is therefore prudent to keep off any of the piping from all water sources. Water consumption by categoryThe water footprint of a country can be categories in either of two ways, internal footprint or external footprint. In this categorization, the internal water footprint is to be calculated from the quantity of water that the country will use in the processes that entail the productions and manufacture of goods and services. This will include the agricultural uses the industrial uses and the domestic used. Mainly for goods and services produced and consumed within the countries. The external water footprint is not that different however, this is the amount of water that goes into the processes that entail the production of goods and services that will be consumed by the people of the country but produced outside the country. This may, therefore, be looked at as the amount of water used in the good that is imported to a country, in this instance Sudan InternalThe internal water footprint in Sudan is quite moderate. Sudan is not very well industrialized country. There are not many industries that produce goods locally that are used locally. The biggest industry in Sudan is the oil industry which does not consume a lot of water. The agriculture industry, however, has a large water footprint. The larger footprint is dues to the use of water in irrigation and demand by plants due to high rates of evaporation due to the high temperatures. ExternalThe external footprint in Sudan is quite high. The country imports a lot of goods. The goods they import range from the clothing industry to the food sector to the technological sector, among others. So as to produce these goods, a water footprint is left behind. Since however the goods that are produced are not used in that country but used in Sudan the water footprint is added to Sudan`s footprint. ConclusionAll in all, the water footprint of a country is an essential statistic as it can very well show the way a country is doing. Water as a resource, a very vital asset, should be used properly and the water footprint should be kept at a sustainable rate because as a resource, it is essential without which there is no life. The practices that have been used to conserve water and use it more effectively should be used implemented all over in a bid to reduce the water waste. There is overwhelming evidence to suggest however that there is an ever-increasing demand for water caused directly by the increase in population. The governments, therefore, should engage stakeholders an looks for ways to increase the water supply to satisfy this demand. There have also been so many activities that individuals and industries have engaged in altogether that have contaminated the water making it non-reusable. Such practices should be avoided altogether and governments should indeed step in to control it and make laws that restrict such vices. ReferencesClothier, B. (2000).
