“Women and men face very different risks and challenges,” said Chitra Nagarajan, a writer and journalist who covers climate change, conflict, and gender. She spoke in this week’s podcast about what’s changed in the Lake Chad region. In the last few years the combination of profound climate change and high levels of insecurity have made life harder for the local population. To get a sense of how recent changes have affected Lake Chad’s residents, Nagarajan interviewed more than 250 people. These are some of her findings.

As fires rage in Australia and in the Amazon, hurricanes ravage the Caribbean year after year, and glacial melt threatens entire communities in the high mountains of Asia and Europe, peace and climate activists might be forgiven for experiencing a growing sense of dread. Environmental events of this magnitude have the potential to simultaneously trigger new ecological disasters and strain social and political systems. The unprecedented challenges borne of the climate crisis will be far-reaching, from large-scale involuntary migration and food and water shortages, to biodiversity and ecosystem loss. These challenges require responses that build social cohesion rather than fuel conflict—responses that are collaborative, just, and climate-resilient.

We are in the decade of action, said Anneka Knutsson, Chief of the Sexual and Reproductive Health Branch at the United Nations Population Fund (UNFPA), at a recent Wilson Center event on midwives’ crucial role in achieving universal health coverage by 2030. The World Health Organization (WHO) has designated 2020 as the Year of the Nurse and the Midwife to celebrate the accomplishments and importance of nurses and midwives in providing not just maternal health care, but care across the lifespan. Currently, 22 million nurses and 2 million midwives globally deliver 80 percent of all healthcare services in low-resource settings. However, the world will need 9 million more nurses and midwives by 2030 to meet rising healthcare demands.

While there are many uses for global data sets and innovative data analysis technologies, the most important thing, Rodolfo Camacho said in this week’s Water Stories podcast, is not analyzing the data. It’s the collaboration among countries sharing data. Camacho, Project Director at Winrock International and Chief of Party for USAID’s Sustainable Water Partnership (SWP), sat down with Lauren Herzer Risi, Project Director of the Environmental Change & Security Program to discuss the importance of big data and machine learning on improving water security.
