More than 80 percent of the estimated 42 million people living in Central Africa’s Lake Victoria Basin depend on fishing or farming for survival. Given this overwhelming reliance on natural resources, the lake’s deteriorating condition – driven by climate change, agriculture, pollution, deforestation, overfishing, and industrialization – has far-reaching implications.

Given that there have been three major peace processes in Sudan’s troubled western province of Darfur, the current escalation of violence indicates that perhaps something about existing approaches is failing to hit the mark. Identifying what is missing is vital – not just for Darfur, but for other areas with similar challenges of state fragility, poverty, and competition over natural resources.

The World Economic Forum recently named water crisis the world’s number one risk for the next 10 years for its potential impact on people and industry. Indeed, as the global community grapples with climate change – and environmental change of all kinds – understanding the fundamental nature if water to human society is crucial. The input report for this year’s World Water Week, released yesterday by the Stockholm International Water Institute, in fact argues that getting water management right is a prerequisite for sustainable development.

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.

In 2007, the world crossed a threshold:  for the first time in human history, the majority of people lived in urban areas. Today, Africa and Asia are the only remaining continents where the rural population outnumbers urban, but they are urbanizing at unprecedented rates. This rapid growth is a double-edged sword. While urbanization spurs economic opportunity and often increases access to infrastructure, it is also widening disparities in health and development, according to a new data sheet by the Population Reference Bureau.

“With current neglect of family planning, the UN’s recent projection of a 2100 world population of up to 12.3 billion is a possibility,” says a report from the University of California, San Francisco’s Bixby Center for Global Reproductive Health. Increased voluntary family planning efforts are needed, the authors contend, to meet existing demand for contraceptives, stabilize the threat of global food insecurity, and reduce carbon emissions that contribute to climate change.

“Tackling climate change could be the greatest global health opportunity of the 21^st century,” asserts the newest report by the Lancet Commission on Health and Climate Change.
