As the international community seeks to articulate a collective vision for sustainable development following the Millennium Development Goals, a vibrant new network has emerged in Madagascar to advance integrated population, health and environment (PHE) initiatives across this island nation.

Much of the time, discussion about climate change is focused on the future – How bad will it be? Will it lead to more conflict? Who will be most vulnerable? But it is in fact a current phenomenon. The climate system is already, for all intents and purposes, irrevocably changed and millions of lives have been changed along with it.

Conflict over environmental resources endangers rural people’s livelihoods and can increase the risk of broader social conflict. Yet joint action to sustain shared resources can also be a powerful means for community building. The Strengthening Aquatic Resource Governance (STARGO) project demonstrated this in three ecoregions: Lake Victoria, with a focus on Uganda; Lake Kariba, with a focus on Zambia; and Tonle Sap Lake in Cambodia. The results of the project were released at an event in Berlin in early July 2014.

Island communities, particularly those from small island developing states, are often reported in policy documents, academic papers and mainstream media as being “most vulnerable” to climate change and disasters. While such a classification might serve to raise awareness of their plight, or be used as impetus for global action, this approach can also result in unintended (and damaging) attitudes and consequences. This is well-illustrated by recent off-the-record discussions with several donors and policy-makers who have inappropriately implied it is “too late” to “save the islands,” given their vulnerability to current and impending climate change impacts.

In 2012, as part of the Every Women Every Child movement, 13 vital health commodities were identified by a UN panel that could save the lives of more than 6 million women and children over the course of five years. There are often significant cultural and behavioral barriers to these commodities reaching people in low- and middle-income countries, but physical logistics is also a major problem.

Since the early 1990s, the rising price of crude oil and other key natural resources – and the resulting drive by governments and private companies to extract those resources – has led to sharp conflicts in Latin America. At the core of these disputes is the clash between national economic interest and the rights of indigenous people inhabiting the land where most natural resources are located.

My grandmother was pleased when I told her I was heading to Ethiopia last November for an international conference focused on population, health, and the environment.
