Several high-profile reports in the last few months have suggested that climate change and natural resource scarcity contributed to the events that have rocked the Middle East and North Africa (MENA) since December 2010. Thomas Friedman is apparently working on a Showtime documentary about the topic. But what exactly was the role of environmental factors in the mass movement?

Natural disasters have dominated news coverage in the past several years, with many observers noting a distressing rise in the frequency and scale of disasters as well as rising costs. Despite these worrying trends, a critical mass of leadership and public support for doing something about it is emerging.

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).

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.

“However rapid change has been over the past couple decades, the rate of change will accelerate in the future,” states the newest quadrennial report from the National Intelligence Council (NIC), Global Trends 2030: Alternative Worlds. Released late last year, the report identifies the “game-changers, megatrends, and black swans” that may determine the trajectory of world affairs over the next 15 years, including demographic dynamics and natural resource scarcity. [Video Below]

“The meek shall inherit the earth” – that seems to be the latest message from the United Nations Development Program.

Some 52 percent of the world’s population lives in cities, a proportion that will only grow throughout the next few decades. Understanding the health challenges facing urban residents is crucial for those who seek to improve human health, especially since many of these challenges differ from those facing inhabitants of rural areas, where global health resources have traditionally been concentrated. At a private meeting on March 4 at the Wilson Center, experts described how factors ranging from climate change and greenhouse gas emissions to reproductive health and rights impact urban health.
