The Mara River traverses nearly 14,000 kilometers in Kenya and Tanzania, flowing through the Masai Mara National Reserve in Kenya and the Serengeti National Park in Tanzania. It is a vital water source for more than 1 million people in the area, as well as for 2 million zebras and wildebeests. In fact, the Mara River Basin is “one of the most ecologically important basins in the world,” according to Basil Mahayni, Deputy Director of USAID’s Sustainable Water Partnership’s (SWP). Communities in Kenya and Tanzania depend on the Mara River Basin for a variety of needs, including drinking water, livelihoods, and ecosystem preservation. Therefore, water security in this basin is essential to ecological health of the basin and its wildlife and the region’s economic development.

Safe water, sanitation, and hygiene (WASH) are vital for human well-being. However, 1 in 3 people (approximately 2.2 billion) still lack safe drinking water, 4.2 billion do not have access to safely managed sanitation services, and 829,000 people die annually from unsafe water and related sanitation and hygiene around the world.

In the Peruvian Andes, where cropland is irrigated and water availability is variable at best, knowledge of highland hydrology is crucial to survival. However, until recently, the locals did not have adequate information to be able to use their water efficiently. So the community worked with a nonprofit to develop a non-specialist/non-researcher run data-gathering project to monitor the water in the region to optimize its use: in short, they developed a citizen science project.

By 2050, the UN estimates that 52 percent of the world’s population will be at risk for water insecurity. Climate change is threatening water availability through increased temperatures and drought, unpredictable rain, and the growing threat of more pollution. Globally, most wastewater reenters the water cycle without being treated, introducing dangerous unseen particles including pharmaceuticals, diseases, and larger waste products such as plastics.

“If you woke up one morning and found the taps in your house were dry, the first thing many of us here would do is pick up our phone and call the utility,” said Gordon Mumbo, Team Leader for Sustainable Water for the Mara River Basin, Winrock International. But for people living in the Mara River Basin, if their taps run dry, there is no utility to call, said Mumbo. Their only choice is to grab the water container and head down to the river where water quality may be poor. Mumbo spoke at the September 30^th event, “Hidden Forces: The Role of Water in Economic Prosperity,” part of the “Water Security for a More Resilient World” series co-hosted by the Wilson Center, Winrock International, and the Sustainable Water Partnership.
