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.

Gains in food production and increased awareness of global food security are threatened by looming losses due to climate change, according to a study published in The Lancet. Marco Springmann et al. calculate that climate change will lead to a 3.2 percent reduction in global food availability per person by 2050, driven by changes in weather patterns, increasing frequency of extreme weather, and potential social disruptions to food production like disease and conflict.

“The Zika outbreak is a result of something; it is the result of the lost attention to sexual and reproductive health issues as a human right and women as subjects of rights,” said Jaime Nadal Roig, the United Nations Population Fund representative to Brazil, at the Wilson Center on April 12. [Video Below]

Zika is a global health challenge. Since its outbreak in Brazil last May, the virus has spread to more than 30 countries and territories and ignited global discourse about family planning, vaccine development, reproductive rights, contraceptive security, and even gender norms.

A study published by the Proceedings of the National Academy of Sciences projects future sea-level rise with a new model, providing crucial information for coastal planning and further impetus to cut carbon emissions. Sifting through data on thermal expansion and retreating glaciers, the two leading causes of sea-level rise in the past century, the authors confirm that sea level is rising at an unprecedented rate.

The climate agreement reached in Paris last December, seen by many as a critical step toward lowering greenhouse gas emissions, was big news – perhaps too big. Pointing to the thousands of articles about COP-21, National Geographic Senior Editor Marla Cone asked at a recent Wilson Center panel, “Is this a wise use of resources, when newsrooms are so stretched thin, to have everybody pretty much chasing the same stories?”

On February 1, the World Health Organization declared the spread of the Zika virus a public health emergency. The declaration was the WHO’s highest level of warning – so dire, in fact, that it has only been declared three times in the organization’s history. We believe that, as with Ebola, the lesson we learn must be the importance of robust universal primary health care services.

The ongoing violence in Syria exhibits the potential for water problems – a historic drought, in this case – to exacerbate existing social and political problems and contribute to humanitarian crises. In a recently released infographic, Circle of Blue combined data from the European Commission Joint Research Center’s Global Conflict Risk Index and the World Resources Institute’s Aqueduct Water Risk Atlas to identify 10 hotspots around the world where water “could play a role in developing or exacerbating humanitarian crises” in 2016.
