Using Big Data Analytics for Transboundary Water Management
›Guest Contributor // Water Security for a Resilient World // July 28, 2020 // By Clara Bocchino & Knowles AdkissonSouthern Africa has experienced drought-flood cycles for the past decade that strain the ability of any country to properly manage water resources. This dynamic is exacerbated by human drivers such as the heavy reliance of sectors such as mining and agriculture on groundwater and surface water, as well as subsistence agriculture in rural areas along rivers. These factors have progressively depleted natural freshwater systems and contributed to an accumulation of sediment in river systems. In a region where two or more countries share many of the groundwater and surface resources, water security cuts across the socioeconomic divide and is both a rural and urban issue. For example, the City of Cape Town had to heavily ration all water uses in 2017 and 2018, as its dams were drying up.
New technology, however, brings new opportunities for improved water governance. In Southern Africa, university researchers and government agencies are joining with international development groups and the private sector to explore how big data analytics can improve the management of aquifers that are shared by two or more countries.

USAID’s New Center for Water Security Signals Progress, But More is Needed
›As the COVID-19 crisis grew this spring, the U.S. Agency for International Development (USAID) revamped its Water Office, renamed it as the Center for Water Security, Sanitation, and Hygiene, and added it to the Bureau for Resilience and Food Security, home to the Feed the Future Initiative.
Placing the Center for Water Security in the Bureau for Resilience and Food Security was a strategic shift. With 70 percent of freshwater use designated for agriculture, this move elevates water as an integral component of resilience and food security. Referencing water security in the Center’s name also highlights the need for water supplies to be managed sustainably and the role that water plays in resilience and peace.

Utilities in Developing Countries, in Financial Tailspin, Try to Keep Water Flowing During Pandemic and Beyond
›The global coronavirus pandemic, now in its third month, is precipitating a financial crisis for water utilities in low- and middle-income countries as many of these service providers face drastic cuts in revenue and rising costs to respond to the public health emergency.

Local Solutions Needed to Stem Humanitarian Crisis in Central America’s Dry Zone
›As the humanitarian community responds to the Covid-19 pandemic, other long-term pressing priorities persist and require innovative solutions. The dry zone which extends across Central America encompassing parts of Guatemala, Honduras, El Salvador, and Nicaragua and a 10-year drought has left 1.4 million people in urgent need of food assistance. The impact of climate change, which includes extreme drought, poses an ever-increasing risk across Central America and contributes not only to food insecurity but also to migration issues that have plagued the continent in recent years.

Toward a New Regional Approach to Water Security and Governance in the Horn of Africa
›Guest Contributor // April 7, 2020 // By Anniek Barnhoorn, Florian Krampe, Luc van de Goor, Elizabeth Smith & Dan SmithAs the global climate changes, climate-related security risks are making the existing political, social, and economic challenges even more complicated. The 230 million people who live in the Horn of Africa are highly vulnerable to the impacts of climate change such as droughts and floods. Political fragility and transnational complexities make water governance a matter of regional high-level politics as well as geopolitical tensions. In short, sustainable water governance is critical for achieving resilient peace.

A Conversation with Rodolfo Camacho on Using Data for Water Security
›Friday Podcasts // Water Security for a Resilient World // Water Stories (Podcast Series) // March 20, 2020 // By Eliana GutermanWhile there are many uses for global data sets and innovative data analysis technologies, the most important thing, Rodolfo Camacho said in this week’s Water Stories podcast, is not analyzing the data. It’s the collaboration among countries sharing data. Camacho, Project Director at Winrock International and Chief of Party for USAID’s Sustainable Water Partnership (SWP), sat down with Lauren Herzer Risi, Project Director of the Environmental Change & Security Program to discuss the importance of big data and machine learning on improving water security.

Can Singapore’s NEWater Spark a Wastewater Revolution in China?
›China is one of the “thirstiest” countries in the world with a per capita water availability a quarter of the United States. With population, pollution, and water shortages growing unabatedly, reclaimed water (e.g., treating wastewater to drinking water standards) could be the answer to China’s water insecurity. In China, extensive research in the 1980s into water reclamation and urban investments supporting infrastructure in the 2000s sparked production capacity in the country to rise from 63 billion gallons a day to 236 billion gallons per day between 2009 to 2015. Today, however, reclaimed water is a mere drop in the bucket meeting less than 1 percent of total urban water use. China could look to the tiny Southeast Asian city-state of Singapore to learn how it tapped reclaimed water to turn its water-scarce tiny island into a high-tech hydrohub.

Enhancing Water Security and the Role of Diplomacy in Africa’s Mara River Basin and Beyond
›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.
