2015 was a deadly year for environmental activism. According to Global Witness, 185 activists were killed, a 60 percent increase from 2014. Of the victims, 40 percent were indigenous people, like Berta Cáceres, who spoke at the Wilson Center last year and was shot and killed in her home in Honduras this March. [Video Below]

The Sustainable Development Goals (SDGs) are an ambitious framework for reducing poverty and improving the lives of billions of people. They were agreed to last year by governments at the United Nations and cover developing and developed countries alike. But how will governments, NGOs, and other organizations go about actually accomplishing them over the next 15 years? [Video Below]

At 1.8 billion strong, the current generation of 10 to 24 year olds is the largest in human history. Approximately 90 percent of these adolescents live in less developed countries. This poses an unprecedented challenge for health systems and social policies which largely struggle to meet the unique needs of young people, according to a new Lancet commission.

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.

Last month, the world came to Copenhagen to focus on how to achieve the Sustainable Development Goals (SDGs) for girls and women. The Women Deliver Conference, the largest gathering on girls’ and women’s health and rights in the last decade, was a huge success. Convening over 5,700 likeminded people from 169 countries was important to reenergize the movement and inspire action. Preaching to the converted is sometimes important. But now it’s time to focus on those who are not yet converted.

How will the 10 billion people expected to be living on Earth by 2050 obtain sufficient and nutritious food? This is one of the greatest challenges humanity faces. Global food systems must supply enough calories and protein for a growing human population and provide important micronutrients such as iron, zinc, omega-3 fatty acids, and vitamins.

As early as 1911, coal miners in Britain carried caged canaries into mining pits. Any sign of distress from the small birds, which are incredibly sensitive to the presence of harmful gases such as carbon monoxide, meant immediate evacuation. Today’s canaries in the coal mine are low-income, minority communities whose exposure to environmental risks in the United States and elsewhere puts them at the frontlines of the global climate crisis.

Anyone visiting Singapore, as I did recently, quickly realizes it is exceptional. A tiny, rich, stable city-state of nearly 6 million people perched uneasily in a region of sprawling mega-countries full of poverty and instability, it also a thriving free market trading and financial center that is meticulously planned and where 80 percent of people live in public housing.
