Water scarcity in Africa

Water scarcity or lack of safe drinking water is one of the world's leading problems affecting more than 1.1 billion people globally, meaning that one in every six people lacks access to safe drinking water. The Joint Monitoring Programme for Water Supply and Sanitation set up by the World Health Organization (WHO) and United Nations Children's Fund (UNICEF) defines safe drinking water as 'water with microbial, chemical and physical characteristics that meets WHO guidelines or national standards on drinking water quality.' Hydrologists generally assess water scarcity by looking at a population-to-water equation that treats 1,700 cubic meters per person as the national threshold for meeting water requirements for agricultural and industrial production, energy, and the environment. Availability below the threshold of 1,000 cubic meters represents a state of 'water scarcity', while anything below 500 cubic meters represents a state of 'absolute scarcity'.

As of 2006, one third of all nations suffered from clean water scarcity, but Sub-Saharan Africa had the largest number of water-stressed countries of any other place on the planet and of an estimated 800 million people who live in Africa, 300 million live in a water stressed environment. According to findings presented at the 2012 Conference on 'Water Scarcity in Africa: Issues and Challenges', it is estimated that by 2030, 75 million to 250 million people in Africa will be living in areas of high water stress, which will likely displace anywhere between 24 million and 700 million people as conditions become increasingly unlivable. The most immediately apparent impact of water scarcity in Africa is on the continent's health. With a complete lack of water, humans can only live up to 3 to 5 days on average. This often forces those living in water deprived regions to turn to unsafe water resources, which, according to the World Health Organization, contributes to the spread of waterborne diseases including typhoid fever, cholera, dysentery and diarrhea, and to the spread of diseases such as malaria whose vectors rely on such water resources, and can lead to diseases such as trachoma, plague, and typhus. Additionally, water scarcity causes many people to store water within the household, which increases the risk of household water contamination and incidents of malaria and dengue fever spread by mosquitoes. These waterborne diseases are not usually found in developed countries because of sophisticated water treatment systems that filter and chlorinate water, but for those living with less developed or non-existent water infrastructure, natural, untreated water sources often contain tiny disease-carrying worms and bacteria. Although many of these waterborne sicknesses are treatable and preventable, they are nonetheless one of the leading causes of disease and death in the world. Globally, 2.2 million people die each year from diarrhea-related disease, and at any given time fifty percent of all hospital beds in the world are occupied by patients suffering from water-related diseases. Infants and children are especially susceptible to these diseases because of their young immune systems, which lends to elevated infant mortality rates in many regions of Africa. Water scarcity has a big impact on hygiene. When infected with these waterborne diseases, those living in African communities suffering from water scarcity cannot contribute to the community's productivity and development because of a simple lack of strength. Additionally, individual, community and governmental economic resources are sapped by the cost of medicine to treat waterborne diseases, which takes away from resources that might have potentially been allocated in support of food supply or school fees. Also, in term of governmental funding, the Water Supply and Sanitation Collaborative Council (WSSCC) estimates that in Sub-Saharan Africa, treatment of diarrhea due to water contamination consumes 12% of the country's health budget. With better water conditions, the burden on healthcare would be less substantial, while a healthier workforce would stimulate economic growth and help alleviate the prevalence of poverty. The Human Development Report reports that human use of water is mainly allocated to irrigation and agriculture. In developing areas, such as those within Europe, agriculture accounts for more than 80% of water consumption. This is due to the fact that it takes about 3,500 liters of water to produce enough food for the daily minimum of 3,000 calories, and food production for a typical family of four takes a daily amount of water equivalent to the amount of water in an Olympic-sized swimming pool. Because the majority of Africa remains dependent on an agricultural lifestyle and 80% to 90% of all families in rural Africa rely upon producing their own food, water scarcity translates to a loss of food security. At this point, with less than a third of the continent's potential using irrigation most of the rural African communities are not tapping into their irrigation potential, and according to the UN Economic Commission for Africa and New Partnership for Africa's Development, 'irrigation is key to achieving increased agricultural production that is important for economic development and for attaining food security'. But for many regions, there is a lack of financial and human resources to support infrastructure and technology required for proper crop irrigation. Because of this, the impact of droughts, floods, and desertification is greater in terms of both African economic loss and human life loss due to crop failure and starvation. Additionally, lack of water causes many Africans to use wastewater for crop growth, causing a large number of people to consume foods that can contain chemicals or disease-causing organisms transferred by the wastewater. Thus, for the extremely high number of African areas suffering from water scarcity issues, investing in development means sustainably withdrawing from clean freshwater sources, ensuring food security by expanding irrigation areas, and effectively managing the effects of climate change. African women and men's divergent social positions lead to differences in water responsibilities, rights, and access, and so African women are disproportionally burdened by the scarcity of clean drinking water. In most African societies, women are seen as the collectors, managers, and guardians of water, especially within the domestic sphere that includes household chores, cooking, washing, and child rearing. Because of these traditional gender labor roles, women are forced to spend around sixty percent of each day collecting water, which translates to approximately 200 million collective work hours by women globally per day and a decrease in the amount of time available for education. Water scarcity exacerbates this issue, as indicated by the correlation of decrease in access to water with a decrease in combined primary, secondary, and tertiary enrollment of women. For African women, their daily role in clean water retrieval often means carrying the typical jerrycan that can weigh over 40 pounds when full for an average of six kilometers each day. This has health consequences such as permanent skeletal damage from carrying heavy loads of water over long distances each day, which translates to a physical strain that contributes to increased stress, increased time spent in health recovery, and decreased ability to not only physically attend educational facilities, but also mentally absorb education due to the effect of stress on decision-making and memory skills. Also, in terms of health, access to safe and clean drinking water leads to greater protection from water-borne illnesses and diseases which increases women's capabilities to attend school. The detriment water scarcity has on educational attainment for women, in turn, affects the social and economic capital of women in terms of leadership, earnings, and working opportunities. As a result of this, many women are unable to hold employment. The lost number of potential school days and education hinders the next generation of African women from breaking out of the cycle of unequal opportunity for gainful employment, which serves to perpetuate the prevalence of unequal opportunity for African women and adverse effects associated with lacking income from gainful employment. Thus, improved access to water influences women's allocation of time, level of education, and as a result their potential for higher wages associated with recognized and gainful employment.
