“Kabul be zar basha be barf ne!” This ancient proverb—“May Kabul be without gold rather than snow”—refers to snowmelt from the Hindu Kush Mountains, a primary source of Afghanistan’s water supply. To recover from years of armed conflict, Afghanistan needs a stable water supply, but its sources are increasingly stressed by severe droughts. The Norwegian Refugee Council estimates that today, 2 out of 3 provinces are impacted by drought, putting two million people at risk of hunger. Improving the country’s water governance—the social, legal, and administrative systems that guide how water is distributed and used—may help it avoid both internal and regional conflicts by stabilizing its economy and its citizens’ livelihoods.

As the Atlantic hurricane season kicks off this month, some coastal communities in the United States and small-island nations in the Caribbean are still recovering from last year’s record-breaking damage. At the same time, the heavy rains pounding the East Coast this week are part of a long-term trend towards more severe heavy rainfall events that have led to deadly floods and threaten critical U.S. military bases. Even on sunny days, cities such as Norfolk and Manila contend with high tide or “nuisance” flooding—a phenomenon that has increased as much as nine-fold since the 1960s, according to NOAA.

Water variability is increasing “due to climate change and to more frequent natural disasters,” said Jonathan Cook, Senior Climate Change Adaptation Specialist with the U.S. Agency for International Development, at the fourth and final event in a series on water security organized by the Wilson Center and the Sustainable Water Partnership. To solve the problem of increasingly erratic water, “business as usual is really not acceptable anymore,” said Will Sarni, founder of WetDATA.org, who called for new, innovative ideas: “Hope is not a strategy.”

Blockchain, the newest technology poised to revolutionize numerous industries, could help decentralize electricity systems across Asia, Europe, Australia and the United States. In Brooklyn, peer-to-peer microgrids allow prosumers—energy consumers who generate small amounts of electricity from renewable sources—to trade energy with other users. Blockchain technology provides distributed ledgers that validate, record, and share each transaction, using smart contracts that automatically execute energy trades when the price and volume of the electricity transaction meet the contracted requirements.

Natural bioshields—wetlands, forests, and urban green spaces—are critical tools for reducing the impacts of disasters on vulnerable communities. Between 1994 and 2014, nearly 7,000 natural disasters occurred worldwide, causing an average of almost 68,000 deaths each year. Climate change, growing populations, and widening economic inequality are all expected to increase the impacts of disasters. Bioshields—nature’s own solutions to natural hazards—can help protect people from these dangerous floods, storms, and heat waves.

In 2014, we met with some of the technical leads of a major Chinese river basin authority in Beijing and asked them whether they were more worried about pollution or climate change impacts. Both, the engineers replied. Pollution affects us every day, they said, but changes in the climate erode our ability to supply drinking and irrigation water, manage floods, and generate electricity.

China must address its environmental and climate change challenges, such as reducing water pollution and building resilience to droughts, floods, and long-term climate shifts. But existing sources of finance have not met the growing demand for environmental projects.

“Most risk in African cities is not catastrophic. It’s not even episodic, but it is every day,” said Mark Pelling, a professor at King’s College, London, at a recent event on urban risk and resilience in sub-Saharan Africa. With rates of rural-to-urban migration reaching record highs, more than half of the urban residents in sub-Saharan Africa live in informal settlements, where they lack basic infrastructure and access to critical resources. Integrated projects like Pelling’s Urban ARK seek to build more resilient communities in cities and informal settlements. “African cities are dynamic and are growing,” said Pelling—but so is the vulnerability of their residents to environmental change, natural disasters, and conflict.

To further its goals to strengthen the global economy, China has already invested $300 billion of its pledged $1 trillion towards its Belt and Road Initiative—a massive infrastructure investment plan that spans 60 countries across Southeast Asia, Central Asia, Africa, South Asia, the Middle East, and Eastern Europe. China’s initiative will shift the world’s political, environmental, and economic landscape.
