Where water and climate change meet

This week, for the first time in over 20 years of UN negotiations, COP21, also known as the 2015 Paris Climate Conference, will aim to achieve a legally binding and universal agreement on climate, with the goal of keeping global warming below 2°C.

Combating climate change is everyone’s business. Reducing emissions and investing in renewable energy, improving city planning and building design standards, developing more efficient transportation, and reducing deforestation (among others) all play key roles in mitigating the effects of climate change. At the same time, countries, industries, and sectors will also need to adapt to changes in the climate as they unfold. Since climate change will significantly increase the variability of rainfall, different parts of the world will become more vulnerable to floods or droughts. Managing water variability — including its nexus with food and energy — is becoming one of the key development challenges facing the world today. Helping the poor adapt to this changing future is everyone’s business.

Why a 4-Degrees World Won't Cause Just One Water Crisis

There is much talk of a water crisis. We who work in water don't really see just one; we see lots of different water crises already now, getting worse as we move towards 2 and eventually 4 degrees above pre-industrial temperatures. Floods in some places, droughts in others, poor operation and maintenance making infrastructure unable to protect citizens in some places, lack of enforcement of rules leading to pollution crises or rampant overuse of groundwater in many others. So there are lots of water crises, some caused by nature, some by humans and most some a combination of the two.

The U.S. Drought Monitor: A Sophisticated Tool, But Do Not Be Intimidated by It

Evaluating the existence and extent of droughts is not an easy task. Not only are droughts "slow-onset" events that creep into the physical, environmental, and social systems of a region, they also have effects that span numerous sectors of a society. The U.S. Drought Monitor (USDM), as recently described by Dr. Michael Hayes from the National Drought Mitigation Center (NDMC) during a recent presentation at the World Bank, provides an example for other nations as they consider how to effectively manage this difficult endeavor of characterizing drought risks and impacts.
