Water is the foundation of human society and will become even more critical as population growth, development, and climate change put pressure on already-shrinking water resources in the years ahead. But will this scarcity fuel conflict between countries with shared waters, as some have predicted, or will it create more impetus for cooperation?

“The combined effects of rapid population growth and climate change are increasing food insecurity, environmental degradation, and poverty levels in Malawi and Kenya,” said Clive Mutunga, a senior research associate at Population Action International (PAI).

There has been quite a bit made in the media and in blogs about low birth rates in industrialized countries. Quite correctly, many people (and countries!) are concerned that unprecedented aging and a dearth of younger people are leading to serious pressure on national budgets from a rising burden of support for the elderly because of  a declining group of tax-paying workers. But the situation is far from equal everywhere, and less is written about that.

Stretching across northern Africa, the Sahel is a semi-arid region of more than a million square miles covering parts of nine countries. It is home to one of the world’s most punishing climates; vast expanses of uncharted and unmonitored desert; busy migration corridors that host human, drug, and arms trafficking; governments that are often ineffective and corrupt; and crushing poverty. It is not surprising then that the area has experienced a long history of unrest, marked by frequent military clashes, overthrown governments, and insurgency.

One year ago, the United States government froze all property of the Central Bank of Iran and other Iranian financial institutions within the United States. The move was part of a broader effort to compel the Islamic Republic to give up its alleged nuclear weapons program. How is it working out?

Although climate change is a global phenomenon, developing countries – especially urban centers – are the most vulnerable to the negative health impacts of climate change.  In “Urban Governance of Climate Change and Health,” a working paper for the Norwegian Institute for Urban and Regional Research, author Siri Bjerkreim Hellevik reviews the existing literature on governments’ responses to climate change and health in developing urban centers. Overall, Hellevik concludes that there is a substantial need for more research specifically linking the two. She offers several recommendations for urban policymakers to consider, including developing an integrated and multi-level approach, and recognizing that human health and urban development are issues of global justice.
