In 2017, four environmental activists were murdered every week on average—most of them in Latin America, and most of them targeted for protesting industries like logging or mining. These shocking numbers may finally start to taper off, if three new initiatives launched just this month are successful at protecting people’s right to a clean environment—and its defenders.

The Mississippi River Valley has been hit by droughts, floods, extreme heat, and tornadoes that resulted in damages totaling over $50 billion since 2011. From 2005 to 2017, that total eclipses $200 billion with each effected state incurring a minimum $5 billion in damages. One positive result in reaction to those natural disasters was the formation of the Mississippi River Cities & Towns Initiative (MRCTI), a coalition of mayors focused on resilience and adaptation programs. Last week, mayors of the ten states along the river met with leaders from the global and North American insurance industry to discuss reducing vulnerabilities and building resilience in the face of climate-related disasters.

“Most risk in African cities is not catastrophic. It’s not even episodic, but it is every day,” said Mark Pelling, a professor at King’s College, London, at a recent event on urban risk and resilience in sub-Saharan Africa. With rates of rural-to-urban migration reaching record highs, more than half of the urban residents in sub-Saharan Africa live in informal settlements, where they lack basic infrastructure and access to critical resources. Integrated projects like Pelling’s Urban ARK seek to build more resilient communities in cities and informal settlements. “African cities are dynamic and are growing,” said Pelling—but so is the vulnerability of their residents to environmental change, natural disasters, and conflict.

“We cannot achieve our goals of ending maternal and child deaths without addressing critical health system barriers around the world,” said Grace Chee of the U.S. Agency for International Development (USAID)’s flagship Maternal and Child Survival Program at a recent Wilson Center event. To improve the lives of mothers and children, health workers must address the underlying causes of poor health outcomes, including systemic weaknesses in health care governance, financing, and human resources.

To further its goals to strengthen the global economy, China has already invested $300 billion of its pledged $1 trillion towards its Belt and Road Initiative—a massive infrastructure investment plan that spans 60 countries across Southeast Asia, Central Asia, Africa, South Asia, the Middle East, and Eastern Europe. China’s initiative will shift the world’s political, environmental, and economic landscape.

“Some people are more vulnerable than others” to climate change, said Judy Oglethorpe, senior director of Multilateral Program Development of the World Wildlife Fund-US (WWF) at a recent event on climate change, biodiversity, and livelihoods. Oglethorpe is the chief of party for the Hariyo Ban (Green Forests) Program, which seeks to increase ecological and community resilience to climate change in two biodiverse landscapes in Nepal. Taking a “multi-scale approach let[s] us focus on the most vulnerable people,” said Oglethorpe, and “work at different scales and across different disciplines…to reduce people’s vulnerability.”

Recently, Nature Climate Change published a new study demonstrating significant sampling bias in the research that informs our understanding of whether climate change will accelerate human conflict. I was a peer reviewer of “Sampling bias in climate–conflict research,” and I wrote an accompanying “News and Views” piece summarizing it. I am fascinated by the issue of sampling bias; it’s perhaps the most consequential and least recognized form of bias in the social sciences, with potentially massive consequences for what we (think we) know about a host of phenomenon.

It should be an excellent time to be a young Iranian: High school and college enrollments in the Islamic Republic rank near the top of Muslim-majority countries. Women have only about two children on average, compared to 6.5 in the mid-1980s. And childhood mortality is projected to approach North American levels in the next 15 years. Yet, as the recent protests show, many young Iranians feel left out. Job growth—especially for young adults—has failed to keep pace with development, while persistently high rates of inflation steadily drive up the cost of living and cut deeply into Iranians’ savings.
