The travails of the last year, when a bat virus infected humans and turned the world upside down, were an unfortunate reminder of the inseparable ties between society and the natural environment.

So it is with water, which will again this year direct the course of history, through events small and large.

What are the large events to pay attention to? What are the trends and flashpoints?

Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

By the end of 2020, Turkey’s long awaited Ilisu dam project will be complete. Turkey argues this new dam will bring power independence and shore up economic stability. As an added bonus, it ensures water resiliency in a water-scarce region. Meanwhile, environmentalists bemoan habitat destruction, and Iraqis worry about water shortages they will experience down river. For the Kurds, the Ilisu dam project wipes out thousands of years of culture. For them, it’s the latest in a methodical cultural extermination which has been their plight since the founding of the Republic of Turkey.

As Beijing prepares to host the 2022 Winter Olympics, China’s environmental activities are once again on center stage. The Wilson Center’s China Environment Forum took the top spot this month with Karen Mancl and Richard Liu’s coverage of the new program report, “Closing the Loop on China’s Water Pollution,” which details what China can learn from New York, Washington, D.C., and Singapore, to advance its wastewater and carbon reduction targets.

When Farhad Ahma returned to his native country last year on a work trip, his first thought was of his small daughter back home. The air around him was so thick with pollution, he couldn’t imagine she would survive the climate in this region of northeastern Syria. Ahma himself struggled to breathe almost as soon as he arrived, nauseated by the heavy smell within a couple hours. He was born and raised nearby, in a city called Qamishli, but he had lived in Berlin for some time now. Returning was a shock to his system.

Trouble is brewing on the Nile. For years, use of the river was mainly about the needs of Egypt, by far the largest and most powerful riparian country in the basin. But since the Arab Spring of 2011, the situation has changed considerably. Egypt’s troubles over the last decade have weakened its ability to project power southward, while upper riparian states—Ethiopia in particular—have enjoyed a period of economic growth and relative stability, which has led them to look at the great river as an important national resource. Tensions have come to a head since Ethiopia announced the construction of the Grand Ethiopian Renaissance Dam (GERD), construction of which is now almost complete. Once full, the resulting reservoir will be larger than the whole of Greater London. Much of the water it holds would have previously reached Sudan and Egypt largely unhindered.

A quiet disruption to the established financial order is underway: Around the world, institutions are pulling their investments out of fossil fuels. Climate activists campaigning for divestment suggest that such economic rearrangements might keep oil, gas, and coal in the ground, curbing carbon emissions. In parallel, some high-profile advocates call for reinvestment in renewable energy. But can the financial sector really drive the structural changes needed to address climate change—and, more fundamentally, climate justice?
