Near the corner of Broadwick and Lexington in London’s Soho neighborhood, a single spot on the ground has influenced more than 150 years of urban development. It’s the location of a water pump that in 1854 physician John Snow pinpointed as the source of contamination leading to a widespread outbreak of cholera in the neighborhood that killed more than 600 people.

If we are to avert the worst of climate change impacts, we need better tools for identifying patterns of displacement and migration around climate extremes. In vulnerable developing countries, increasingly frequent and intense storms will likely exacerbate current patterns of displacement and permanent migration. Displacement often leads to humanitarian crises in the short term and can derail progress toward development in the long term. Because of this dangerous potential, displaced persons and migrants are a common focus in humanitarian responses. However disaster responders must often “fly blind” without the benefit of current, accurate information about the worst-affected populations. To better respond to the impacts of climate change as they unfold, we will need more rapid, cost-effective, and accurate methods for identifying patterns of displacement and migration.

Overfishing by foreign fleets in West Africa is leading to devastating social and economic consequences. In a report from the Overseas Development Institute, an independent think tank based in London, researchers use satellite data to assess the scale of two kinds of illegal, unreported, and unregulated fishing: “reefers,” or large-scale commercial vessels receiving and freezing fish at sea and at port, and large refrigerated container ships that are registered in countries with less stringent enforcement regulations than that of the ship’s owners.

The once-every-three-years Women Deliver conference has become a major coalescing force for various global health and development efforts aimed at women and girls. “We operate at a global level, influencing the agenda” by focusing on the “four Cs”: convening, communicating, capacity-building, and catalyzing, said Susan Papp, director of policy and advocacy for Women Deliver. [Video Below]

The International Expert Forum (IEF) is a series of seminars meant to facilitate dialogue between experts and policymakers on peace and security. Meeting in Stockholm this past May, the forum explored the connections between environmental issues, peacebuilding, and conflict while considering how environmental governance can aid in peacebuilding.
