While it is intuitively clear that economic growth is related to water security – understood here as both water availability and also exposure to water-related risks such as drought and floods – there has been very little empirical evidence of this relationship to date.

President Obama’s recently announced Clean Power Plan – potentially a major turning point in the fight to contain greenhouse gas emissions and stop the slide toward an ever-warming Earth – is oddly both a courageous step in the right direction and codification of a process already underway.

REDD+, a global framework designed to reward governments for preserving forests, has pledged nearly $10 billion to developing countries. But minorities, indigenous people, the poor, and other marginalized groups that live in forest areas often end up paying more than their fair share of the costs of environmental cleanup and conservation while getting less in return.

Food and water are tied to one another fundamentally. But in addition to their biophysical relationship, human systems intervene, whether through pricing schemes and trade agreements or shifting patterns in consumption and taste.

Although treating wastewater generally ranks alongside police and fire safety, schools, and transit as the top priorities of any sensible city hall, new ideas about cleaning up sewage almost never attract headlines or TV airtime.

Brown, who is now California’s governor, wanted the city staffer he called “Creek Lady” to describe the most formidable ideas she had to conserve natural areas, make parks more beautiful, and clean up the city’s waters.
