A study published in PNAS highlights the unpredictability of the impacts of climate change on water resources by comparing detailed simulations in mountain areas of Chile and Nepal. Authors Silvan Ragettli, Walter W. Immerzeel, and Francesca Pellicciotti study the response of river flows to a significant decline in glacier areas in the Juncal catchment of Chile and the Langtang catchment of Nepal at higher spatiotemporal resolutions than any previous study.

Although separated by a thousand miles, the women of the Malaysian state of Sarawak and the Filipino island of Mindoro are united by a major struggle: climate change. As rainfall patterns grow increasingly unpredictable, natural disasters become more frequent, and drought ravages once-arable land, women are on the frontlines in both communities.

More often than not in the discourse around gender and climate change, the word “gender” is used primarily to refer to women. There is no disputing that women are acutely vulnerable to the effects of climate change in ways that are different than men and sometimes hidden. However, this interchangeable use of words neglects other dimensions of gender, sexual orientation, and sexual identity. As a result, we are missing important ways gender impacts people’s experiences with climate change.

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.

The eye catching headlines are familiar. “Water Wars” are imminent or already underway in the latest drought or dam-building hotspot. Such “wars” often extend to farmers battling over irrigation diversions, but at times countries are the players. Senior leaders are often quoted suggesting transboundary water theft constitutes a casus belli. Security officials are obliged to investigate.

At USAID we recognize the threat poor sanitation combined with rapid urbanization presents to human health, dignity, and prosperity. This is why we have made urban sanitation a global priority for the Agency. During a recent visit to India, I was able to see some of the work being done to bring sanitation services to urban areas, and had the good fortune to meet some inspiring women who are advancing these efforts in their communities.

In 1970, Cyclone Bhola slammed into East Pakistan – present day Bangladesh – with sustained winds of 150 miles per hour, killing as many as half a million people. In 2007, Cyclone Sidr killed 3,406 people in Bangladesh. This year, Cyclone Roanu killed just 30. What’s behind this huge decline in mortality? What has Bangladesh done differently?

Despite a long history of confrontation and simmering tensions, three senior retired military leaders from Pakistan, Bangladesh, and India urge the nations of South Asia to unite around a common rising threat in a new report.
