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.

When I began working in Liberia right after the Accra settlement ended Liberia’s civil war in 2003, I could not help worrying about whether the peace would last. Burnt-out cars lined the streets of Monrovia, bullet holes scarred many of its buildings and the wary U.N. peacekeepers manning checkpoints behind sandbags and barbed wire reinforced the sense that violence could flare up again at any time.

Climate change and youthful demographics can combine to create security risks in already fragile contexts, according to a new report commissioned by UNICEF UK and co-authored by the London-based research organizations International Alert and the International Institute for Strategic Studies.

The damming of a river that feeds the world’s largest desert lake could lead not only to less drinking water for thousands of Kenyans, but international conflict between tribes for what little water remains.

It’s been 14 years since the UN Security Council adopted Resolution 1325 acknowledging women as important agents of change in recovery from conflict and peacebuilding generally. But between 1992 and 2011, only four percent of signatories in 31 major peace processes around the world were women, and only 12 out of 585 peace agreements referred to or made provisions for women’s needs in the reconstruction process.

Despite some critics, the recent U.S.-China agreement over carbon emissions has sparked remarkable optimism in global climate negotiations. It’s also opened the door to new bilateral engagement between the U.S. and Chinese environmental communities on other issues, including China’s massive air pollution problems (16 of the world’s 20 most polluted cities are in China).

Climate change and conflict – what’s the relationship? In a recently completed set of field-based studies for USAID, the Foundation for Environmental Security and Sustainability set aside “yes-or-no” questions about whether climate change causes conflict and replaced them with pragmatic and politically informed questions about how climate change is consequential for conflict in specific fragile states.

Water is a key ingredient for peace, especially in the Middle East. The Jordan River, which forms the border between Israel, the Palestinian West Bank, and Jordan, is central to the interrelated political and environmental challenges facing the region. Addressing these challenges requires not only high-level diplomacy but also direct, people-to-people engagement, which can form lasting relationships that go beyond water, said experts at the Wilson Center on October 17.
