This year’s World Water Day is taking on a broader theme than years past: sustainable development. The theme makes sense as two major international processes – the drafting of the Sustainable Development Goals to replace the Millennium Development Goals, and the most anticipated UN Climate Summit in years – are taking place in 2015. Decisions made over the next nine months will play a huge role in relationships between nations and global development priorities going forward.

The Sahel – spreading from the Red Sea to the Atlantic as the Sahara Desert transitions to Sudanian savanna – is drought prone and suffers from chronic food insecurity. Yet, the region also boasts the highest fertility rates in the world, and the highest rates of marriage for young girls. This creates unique vulnerabilities that are being compounded by climate change, says ECSP’s Roger-Mark De Souza in an episode of Wilson Center NOW.

You could say the people living along the banks of the Thondwe River in southern Malawi were lucky. At least they’d been warned of the flash flood in early January that would burst through an earthen dike, wash away their homes and crops, and leave more than 4,000 of them homeless.

India is one of the most water-challenged countries in the world, from its deepest aquifers to its largest rivers. Groundwater levels are falling as farmers, new urban residents, and industries drain wells and aquifers. What water is available is often severely polluted, and the future may only be worse, with the national supply predicted to fall 50 percent below demand by 2030.

In 2009, the U.S. Congress passed a five-year, $7.5 billion aid package for a country it had all but abandoned just 10 years earlier. Indeed, if one word can summarize the U.S. relationship with Pakistan, “volatile” might be it. Since the September 11 attacks, the U.S. has appropriated nearly $61 billion in aid to Pakistan – more than twice what it received since independence in 1947.

Though the bull market for metals and energy may be ending, global food prices remain stubbornly high. The inflation-adjusted FAO Food Price Index is down from the near historic heights of 2007-08 and 2011 but still higher than at any point in the previous 30 years, putting a brake on several decades of progress in reducing world hunger.

The story of Uma Tudu captures the endless cycle of poverty, violence, and suffering faced by too many girls in the northeastern Indian state of Assam.* At 16, following floods that destroyed her village, she traveled more than 1,600 kilometers to Delhi, lured by the promise of a good job and a good life. Instead she was sold as bonded labor.

While much of the debate around climate financing focuses on “how much,” an equally important question is “how?”
