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.

Climate change is expected to affect rural to urban migration and Omar O. Chisari and Sebastian Miller, in a recently released working paper by the Inter-American Development Bank, analyze the various policy options available in two cases: domestic migration to São Paulo, and international migration from Bolivia and Paraguay to Argentina. Migration into cities will impact climate change mitigation strategies.

A report by the European Union on global food security finds 240 million people are in food stress thanks to conflict, refugee situations, flooding, drought, and El Niño. Part of a 2012 commitment by the EU to better target the root causes of food insecurity, the report analyzes the hunger situation in 70 countries and provides deeper analysis for 20.

Population, reproductive health, and environmental sustainability are inextricably linked. Growing populations place increasing demands on the environment, while meeting the reproductive health needs of populations usually slows their growth. Often, however, policymakers, scholars, and journalists discuss these issues separately, as if unrelated.

In the southwestern part of Indonesian Borneo, known as Kalimantan, there’s a small town on the outskirts of an incredibly diverse forest where the community has turned from illegal logging to stewards of the land.

Over the past decade, the number of undernourished people around the world has declined by around 167 million, to just under 800 million people. However, this positive trend glosses over a stark reality: Food insecurity is increasing in the world’s mountains. This pattern has been under-recognized by development experts and governments, a dangerous oversight with far-reaching social and environmental repercussions.

Melinda Gates announced a new $80 million Bill and Melinda Gates Foundation commitment to global data collection in a May 17 address at the Women Deliver conference in Copenhagen. Over three years, the foundation’s efforts will focus on filling gaps in data about women’s unpaid labor, improving the accuracy of data around land and property ownership, and using that data to inform civil and government decision-makers about the effects of their existing programs and recommend areas for improvement.

Everywhere you look these days, you find storytellers. I’ve found myself going to fewer concerts after work and more storytelling nights. Podcasts have sprung up dedicated to the craft of narrative. It’s a brand I hear friends use to define themselves: “I’m a storyteller.” If you’re under 30, it’s a natural and ubiquitous part of the milieu.
