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.

2015 was a historic year for international commitments to sustainable development, climate change action, and new kinds of peacebuilding. For governments and policymakers, now comes the difficult task of living up to those commitments. [Video Below]

As international funding to support environmental management and development increases, the danger of associated corruption grows and requires greater attention. Small-island developing states (SIDS), greatly exposed to the damage caused by climate change, are particularly vulnerable. These small, trailblazing countries in the Pacific, Caribbean, and Indian Ocean are making progress in addressing climate threats, but will need international support and local commitment regarding rule of law and corruption in the climate sector as they try to prevent the worst effects of climate change and find a sustainable way to develop.

“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]

Drought in Ethiopia, exacerbated by El Niño, has put more than 10 million people in a position of being unsure how long they will have food and where it will come from next. Inevitably, the drought has been compared to the infamous drought of 1983-1984 that led to the worst famine in the country’s history, making millions destitute, and contributing to the deaths of 400,000. But Ethiopia is in a very different place today than it was in 1983.

Surrounded by water, the Philippines is especially vulnerable to climate change. Its islands and its people are enduring increasingly unpredictable rains, intensifying cycles of flood and drought, and strengthening storms forming in the Pacific. These changing weather patterns have not only derailed livelihoods and agricultural productivity in rural areas, they have also worsened water insecurity in cities, where 45 percent of the population live.
