Before world oil prices collapsed late last year, shop owners closest to the banks of the Rio Grande River in Piedras Negras joked that they could hear the groans of Texas drilling rigs advancing toward their fast-growing northern Mexico city.

Researchers have been warning about future water scarcity for decades, but new data reveals a majority of the world’s largest aquifers are already running out of water.

The discovery of oil in Chad in 1969 did not yield many immediate benefits for a population that would soon be wracked by civil war, but hopes were high by the late 1990s. Chad had largely stabilized, and a new, World Bank-backed project to build a pipeline through Cameroon to the Atlantic Ocean coast was touted as a model for socially and environmentally responsible oil exploitation in developing countries.

It shouldn’t come as a surprise that Yemen has collapsed – again. A country that has split and been pulled together before, has the youngest and fastest growing population in the region, is running low on oil and water, and possesses a “personalist” government rather than stable institutions, was on the top of every expert’s list as the fragile state most likely to fail next.

The past decade has brought ground-shaking changes to global energy markets. The unconventional fuel boom has unexpectedly reduced U.S. dependence on oil imports, while in the Asia-Pacific region, energy-constrained nations are increasingly reliant on foreign sources to meet their soaring demand. With the U.S. slated to export liquid natural gas (LNG) to Asia as early as 2017, a new energy era has come.

With the Obama Administration moving forward on emissions reductions, the deadline for drafting the Sustainable Development Agenda, and a highly anticipated global climate summit in Paris, 2015 promises to be a crucial year for climate policy. “In many ways, last year was the year of building momentum, and this is the year of getting the work done,” said Lisa Friedman, deputy editor of ClimateWire, at the Wilson Center on January 5. [Video Below]

On the heels of a landmark U.S.-China climate agreement, 2015 will be a critical year for China’s environmental and energy policy. A revised and much stricter Environmental Protection Law went into force on January 1; new amendments to the Air Pollution Law are likely to be put in place; and the National Development and Reform Commission will draft a new five-year plan.
