Rainwater Harvesting Revolutionized by an App
Technology has played a significant role in the reduction of global poverty. Two particular areas technology has improved impoverished communities are water access and water quality. For instance, a newly developed piece of technology showcases the potential for enhancing water security throughout Africa. The key is effective rainwater harvesting.
Water Supply Threats
In Africa, increasing water access and sanitation has become a top priority. Consequently, many organizations — the United Nations, the African Union, and the African Development Bank — have come together to solve the water crisis by sponsoring The Africa Water Vision for 2025. It warns that African water resources are threatened by pollution, environmental degradation, and a lack of responsible protection and development.
A New Smartphone App
Despite these threats, a new smartphone app has empowered Africans to efficiently procure their own water. Rainwater Harvesting Africa (RHA) is a smartphone app that the U.N. Environment Programme and the U.N. Educational, Scientific and Cultural Organization jointly developed. It enables Africans to use rainwater harvesting systems to obtain their own water.
Usually, rainwater is harvested through the construction of a central water tank that connects to various downspouts. But, with this app, households are able to capture rain runoff for essential personal use.
RWH Africa utilizes real-time meteorological data to track rain patterns throughout Africa. App users can input their location, the area measurement of their rooftop, the number of people living in their household, and how much water they use per day. The app uses this information to calculate how much water can be harvested at a given time for the needs of the user. Additionally, the app provides images and directions detailing how to construct rainwater harvesting systems with locally available materials.
In addition, RWH Africa has built-in resources that can improve access to water throughout Africa. They can capitalize on increased technological infrastructure to expand its user base. GSMA estimates that 475 million people in Sub-Saharan Africa alone will become mobile internet users within the next five years, and 27% of their mobile internet connections will be on 4G. With increased smartphone usage throughout the continent, more Africans will be able to access this powerful tool of water procurement.
Although Africa needs to increase its internet capacities to maximize the app’s effectiveness, it has a more than sufficient water supply. In 2006, the U.N. Environment Programme and World Agroforestry Centre issued a report indicating that Africa alone receives enough rainfall each year to meet the needs of nine billion people. According to the report, Africa is not water-scarce, but the continent is just poorly equipped to harvest its water resources adequately and safely. RWH Africa gives Africans the knowledge they need to personally capture these vast water resources.
Furthermore, rainwater harvesting is low-cost and easy to maintain, making it widely accessible. According to The Water Project, a household rainwater harvesting system can hold up to 100,000 liters of water. This is enough to allow communities to decouple from centralized water systems that are subject to incompetent or corrupt management. Rainwater harvesting hence enables individuals to take matters into their own hands and decrease their reliance on undependable municipal water sources.
Technology Can Beat Poverty
As internet connection and smartphone usage expand, new solutions to poverty issues, such as water insecurity, will reach more people. RWH Africa serves as an educational and practical tool for rainwater harvesting and thus can be used as an example for similar future efforts. It signifies a positive outcome of increased cooperation between international organizations and local communities in combating global poverty.
