You might think that conflict over water is inevitable as rising temperatures and changing climates are expected to constrain supplies in the coming decades at the same time that expanding consumption standards and growing populations are expected to boost demand. But you’d be wrong, according to the United Nations – and they’re launching the International Year for Water Cooperation this week to make that point.

Water resources, energy, and land use are so mutually dependent that climate-related disruptions to any one of them could lead to economically devastating ripple effects – especially as a growing population puts increasing strains on all three. That’s one conclusion of a recent report issued by a federal advisory committee charged with assessing how climate change has already affected the U.S., and what the future holds.

By the time the violence had died down, more than 80 people lay dead and hundreds were left homeless.

Yet there was scarcely enough water – the resource the Maasai and Kikuyu tribes were fighting over – to wash away the blood that had stained this part of Kenya’s Rift Valley.

2012 witnessed a remarkable number and extremity of environmental conditions, from Hurricane Sandy and the U.S. drought to wildfires in Siberia and drought-driven blackouts in India. Arctic sea ice melted to its furthest extent in recent history. The energy landscape continued to change as well, from the launch of the U.S. Navy’s Great Green Fleet to the first liquefied natural gas shipments across the Arctic. As President Obama clearly stated in his second inaugural address, climate change is heightening both our risks and the need to respond, but tying together all of these issues is a highly complex endeavor.

The horizon gleams with a golden hue from the wheat fields that spread in all directions here in Shandong, a prime food-growing province on the lower reaches of the Yellow River. As hundreds of farmers spread the wheat like massive carpets to dry on country roads, combine machines are busy harvesting the grain. The same afternoon that the wheat harvest is finished, farmers will already be planting corn and other crops. This is how China feeds 1.4 billion citizens and millions of livestock.

Does access to quality water and sanitation have an effect on maternal health outcomes? That was a surprising topic of discussion on day one of the second-ever Global Maternal Health Conference hosted this week in Arusha, Tanzania.

Surprising because, to be honest, I did not think there would be strong disagreements over the relationship between water and sanitation (WASH) and maternal health. In my work with the Comparative Urban Studies Project, the two seem to be clearly linked.

The Wilson Center Policy Briefs are a series of short analyses of critical global issues facing the next administration that will run until inauguration day.

Seven billion people now live on Earth, only a dozen years after the global population hit six billion. But this milestone is not about sheer numbers. Demographic trends will significantly affect the planet’s resources and people’s security.

High mountain regions face grave environmental challenges with climate change impacts already as severe as any place on earth. Temperature increases are expected to be greater at higher altitudes than at sea level, and glaciers and snowfields are retreating in many areas, increasing the risk of catastrophic glacial lake outburst floods, affecting fresh water supplies for hundreds of millions of people, and exacerbating territorial and natural resource disputes.
