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.

“As we go forward, we will discover that 2015 was when we really started getting serious about transdisciplinary challenges inherent in sustainable development,” said Melinda Kimble, senior vice president for programs at the UN Foundation, at the Wilson Center on April 13. [Video Below]

Specimens of goldenrod sewn into archival paper folders are stacked floor to ceiling inside metal cabinets at the Smithsonian National Museum of Natural History. The collection, housed in the herbarium, dates back to 1842 and is among five million historical records of plants from around the world cataloged there. Researchers turned to this collection of goldenrod – a widely distributed perennial plant that blooms across North America from summer to late fall – to study concentrations of protein in goldenrod pollen because it is a key late-season food source for bees.

Blackened rivers snake the ring roads of Beijing, carrying pollution and often smelly water from one end of the city to another. The most polluted of these have been dubbed “foul and filthy” rivers (黑臭河) by China’s Ministry of the Environment (MEP) and Ministry of Housing and Urban-Rural Development (MOHURD). However, the government has decided to clean these up – and is enlisting the help of the public to do so.

The saying goes, what hasn’t been counted doesn’t count. Our latest datasets for the Environment and Gender Information (EGI) platform are proving this true.

When I heard of the horrific murder of Berta Cáceres, a Honduran environmental activist who had spent years fighting to protect her community’s traditional lands, I was shocked – though perhaps I shouldn’t have been.

Africa has its share of challenges, but it also leads the way in creative development responses. Take the Lake Tanganyika area in Tanzania. Daily life is hard. There are few roads. Cellphone service is patchy. You must travel by boat for seven hours to reach the nearest hospital. And if you have an obstetric emergency, there is no doctor in the village to help you.

Developing countries are in a pitched fight against the effects of climate change, and women, playing prominent roles in agriculture and household resource collection, are “at the front lines in the battle,” writes UN Framework Convention on Climate Change Executive Secretary Christiana Figueres, in a new report.
