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.

In an effort to scale-up climate change mitigation, the largest private sector engagement in the history of the United Nations was drafted to fund clean technology projects in developing countries. Carbon credits were to offset pollution in developed nations and pay for clean energy projects in developing countries. But many developed countries, including the United States, spurned the agreement, preferring to manage greenhouse gas emissions internally and build or retrofit infrastructure in ways that directly benefited their economies. The ambitions of the Kyoto Protocol, which went into effect in 2005, were subsequently stranded and then scrapped.

“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]

I recently returned to Washington, DC, after 10 days in India. New Delhi was warm, moist, crowded – and buzzing with mosquitoes. Fortunately, at least for now, their bites are little more than an itchy nuisance, which is just as well.

In January, over the objections of indigenous groups that live there, the government of Ecuador sold oil exploration rights to 500,000 acres of the Amazon to a consortium of Chinese companies. Whenever we hear about stories like this, there is a tendency to think: How can this happen? How can obscenely rich investors run roughshod over the land, livelihoods, and rights of impoverished local communities, and with utterly no consequences?

People in developed countries rarely think of weather in life-or-death terms. But millions in the developing world have no choice but to do so. The global rich have stable governments, savings accounts, insurance, and more to fall back on when disaster strikes. People in poorer countries don’t, so they’re often faced with tough decisions in times of drought: Sell the only ox for food and plow by hand next year? Take the kids out of school and put them to work chopping firewood for extra cash? Abandon the farm and family to look for work in the city?

“The Zika outbreak is a result of something; it is the result of the lost attention to sexual and reproductive health issues as a human right and women as subjects of rights,” said Jaime Nadal Roig, the United Nations Population Fund representative to Brazil, at the Wilson Center on April 12. [Video Below]
