From the 2004 Indian Ocean tsunami to Superstorm Sandy, the last decade has seen an incredible array of natural disasters. Of course, disasters of all kinds are nothing new, but, thanks to the growing scale and interconnectedness of the human enterprise – and the damage we have done to the natural world – the frequency, scale, and consequences of today’s calamities are truly without precedent.

Balbine is moving through her coastal village of Andavadoaka with a sense of urgency. Normally she works as a community-based distributor for Blue Ventures’ integrated population, health, and environment (PHE) program in southwest Madagascar, providing health information and products to her community. However, since Cyclone Haruna swept through the region several weeks ago, Balbine has been especially busy distributing diarrhea treatment kits to mothers caring for sick infants, providing families sleeping out in the open with mosquito nets to protect against malaria, setting up water filtering stations, and emphasizing the importance good hygiene practices.

Much ink has been spilled on the growing trend of global land grabs – land purchased en masse in developing countries like Ethiopia by foreigners mainly for agricultural export. But along with land, investors often also gain the right to use local water, and sometimes with little consideration for local livelihoods. Fred Pearce recently looked into these “water grabs” in a series for National Geographic.

A well-known Chinese proverb describing the relationship between the central government in Beijing and its people says, “Heaven is high and the emperor is far away” (天高皇帝远, tian gao, huang di yuan). It’s not too far of a stretch to apply the same proverb to the current state of China’s environment sector, where relatively strong pollution control laws are poorly enforced on the ground.

While it can be convenient to think of human health and the environment as unrelated silos, they are in fact closely related. The United Nations Environment Program (UNEP) recently released a report underscoring this point especially for Africa, where large numbers of people are directly reliant on natural resources for their livelihoods.

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.
