Demand for water in Africa is soaring

Today, more than one out of nine people in the world lack access to safe drinking water, namely 783 million people, and more than two out of five, lack adequate sanitation (2.5 billion people). Every 20 seconds, a child dies as a result of poor sanitation that is 1.5 million preventable deaths each year. Seen over a day, more than 4,500 children die from waterborne diseases despite the continent boasting of having numerous natural water sources such as lakes, rivers, streams, ponds, springs, rainwater, aquifers, and ocean water.
The most hit hard is Africa, roughly 40 percent of Africans, mostly the rural poor, will not get access to clean water any time soon, a fact that exacerbates poverty, hunger, and disease. And while rich countries worry about obesity, recent droughts in the Sahel and Horn of Africa have forced millions of Africans to flee their ancestral lands in search of food.

Meanwhile, a doubling of the continent’s population in the first quarter of this century is set to significantly increase demand for Africa’s water too, risking groundwater depletion and a gradual destruction of precious ecosystems.

This state of affairs is further compounded as the world gets warmer, the rains pour heavier and oceans rise, making rural inhabitants migrate to cities in their millions. African cities are under dual pressure from uncontrolled urbanization and flooding, worsened by climate-induced water stress. The Intergovernmental Panel on Climate Change expects climate change to hit Africa harder than anywhere else.
Improvements in both of these areas have been made in the past decade, but huge numbers of Africans still live without these basic necessities.  Lack of access to water and sanitation is a matter of life and death. Contaminated water and inadequate sanitation help transmit diseases like diarrhoea, cholera, dysentery and typhoid.

The impact of inadequate water access stretches across all sectors of development: health, education, gender equality, economic development, food security, and even national security. Safe, accessible water is essential to the health of people and communities, critical to ecosystems, and indispensable for economic prosperity.
Sustainable safe water access is the foundation for a sustainable community. It is also important to hygiene, hydration, sanitation, safety, and opportunity. Those with it in the developed world often take it for granted, but if you live in an area without access to clean water, it drastically affects your sanitation and your health—and for women, in particular—it can be devastating, because the women are often the people in the community who are spending their days and risking their safety to find and carry home the water.
Solutions to the crisis
·         My first take is that we need to get serious about water, which is central to several critical challenges from health and hunger to energy and security. Water is more than a commodity – it’s a source of life and livelihoods. Every culture in the world recognizes water as the source of all life, and yet the international community has held back from giving access to water the prominence and backing it deserves.
·         Because sub-Saharan Africa is subject to more extreme climate variability than other regions, it needs improved water storage capacity. Large dam projects would create a more sustainable reserve of water resources to combat the burden of climate fluctuations, but other disagree, stating the harmful environmental impact of large dams.
·          More water treaties are needed; transboundary water agreements have cultivated international cooperation and reduced the "probability of conflict and its intensity."
·         Better donor emphasis on water development is needed. I am concerned that global environmental issues are upstaging Africa-specific issues of water development.
·         Small-scale agricultural improvements also offer a solution to water stress, including the harvest of water in shallow wells, drip irrigation for crops, the use of pumps, and other technological innovations. The key thing is the concept of green water as opposed to blue water. Blue water is the water we see in streams. Green water is the water we don’t see in the soil, and green water accounts for two-thirds of the water supply." Farmers can access green water through drip irrigation (systems that slowly and consistantly deliver water to plant’s toot system), supplemental irrigation (supplementary to natural rainfall rather than the primary source of moisture during periods of drought) and rainwater harvesting (the collection of rainwater for crops, which reduces reliance on irrigation). Crops can grow poorly even during periods of rainfall, and most farms in Africa suffer from nitrogen and phosphorus depletion in soil. One way to assuage water stress in terms of food scarcity is to increase water-holding capacity with organic fertilizers that would increase availability and efficacy of green water.
·         The hydrological, engineering and social sciences have great roles to play to enable African economies overcome the acute and often devastating water problems confronting them now and in future decades. This can be done through a framework that promotes efficiency, equity and sustainability.
·         A more comprehensive approach to water resources management that enables sound policy development and strong institutional set-up, private sector initiatives and effective river basin management is needed and would constitute the pillars of sustainable water use for human consumption and development.
·         The expansion of supplies may be achieved through scientifically designed water harvesting technologies and water transfers from areas of water surplus to those of water deficit. Science could also promote resource intensification to achieve a higher output per unit of water, particu- larly in agriculture, which accounts for some 88% of the continent's water allocation.
·         Agrohydrological studies should continue to provide increasing guidance for economic diversification in favour of activities, or crops and species, which consume less water. The social sciences should provide appropriate economic and regulatory instruments for combination with technological ones for water demand management. Science offers many possibilities for helping to resolve the problems plaguing Africa's water sector. This can be achieved by bringing about a balance between demands for and supply of water for the competing needs of the different sectors of the national economies. Science also offers the opportunity for a better understanding of the interrelationships between the hydrological and biogeochemical cycles on the one hand, and food production on the other, and provides the framework and tools for linking water resources planning with landscape/ecological planning.
·         Development partners will have to support Africa’s quest to develop its capacities for the implementation of SDG6, especially in the development of bankable water and sanitation projects. Closing inequality gaps in the accessibility, quality and availability of water, sanitation and hygiene should be at the heart of government funding and planning strategies.
·         Governments must, however, lead the efforts while external agencies work in a way that supports and builds government capacity to lead and to succeed. All stakeholders must therefore commit to work collectively and adhere to key behaviours that strengthen countries’ capabilities to deliver permanent and accountable access to water and sanitation services.
Furthermore, lack of access to clean and safe water has frustrated poverty reduction efforts and hindered economic prosperity. For instance, Sub-Saharan Africa loses 5% of its GDP per year as a result of water-related challenges. In addition, 40 billion hours per year, which could have otherwise been used on productive activities, are spent searching for water.
Improved access to quality water is a long-term goal that requires more than humanitarian funds. Failure to deal decisively with water and water-related issues at the country level, as well as in the context of large drainage basins involving several countries, could further result to more serious Water problems in Africa.
Finally, we cannot enter the 21st century with the usual commercial approach we are used to having concerning water management. We need a political determination; we must make a realistic assessment of our water management capabilities in specific circumstances. We must dare. We must show unfailing commitment to equity.

Sustainable water management represents long term security for all of us therefore urgent action is needed if we are to avoid a global water crisis.  Together, we must all aim to ensure sustainable access to safe water and sanitation for the most vulnerable communities through innovative partnerships and creativity #WaterAccess #Sustainability #SDG6 #SDGS #HumanityandInclusivity #AfricaWaterSolutions #SustainableCommunities
