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.

Stacy Ann Walker could have died.

During what she thought was going to be a normal exam, Stacy learned that she would need to have a C-section. While recovering in the hospital, she began to have breathing problems and after some testing was told that her heart had been scarred by an earlier bout of rheumatic fever. Shortly after, she also learned that she had heart failure, an enlarged heart, and problems with multiple heart valves.

She was 29.

The urgency to address climate change is only growing. As youth step up and are increasingly vocal about climate change, international negotiations—most recently at COP25—fail to deliver the ambitious global action required for effective response.

Where does this leave the communities most at risk from climate impacts? How can they adapt and transform in the face of enormous threats, sometimes to their very existence? With researchers and policy experts often focused on technological fixes and pushing new solutions to specific threats, it’s easy to assume that transformation is underway to respond to the new climate reality. In reality, transformative change is tough—especially when up against ingrained habit, culture, and a lack of political and financial resources to support it. Perhaps most importantly, transformative change requires effective leadership and champions—those people who build political will and create momentum to move policy innovations or on-the-ground action.
