Food security and proper nutrition are essential elements for the good health and wellbeing of individuals and communities. Proper nutrition increases productivity and subsequently helps lift families out of poverty. However, an estimated 800 million people are chronically malnourished across the world. Globally, more than 3 million children die each year due to illnesses caused by malnutrition.

For all its flaws, the United Nations remains the only plausible forum for engaging broad global challenges like sustainable development. The most important environmental achievements of the past 40 years – the rise of environmental awareness, the birth of key ideas such as sustainability or the common heritage of humanity and the most important global treaties for environmental protection – all bear the UN stamp in one way or another. We could have added environmental human rights to that legacy last month, but we failed.

When war breaks out, what happens to the weather forecast? Violent conflict disrupts many essential services in developing countries and one of the most overlooked is meteorology, which has surprisingly big consequences for farmers, policymakers, and the aid workers who are there to help.

The announcement in Washington on September 24 that President Xi Jinping is committing China to a national carbon trading system is the latest step in an important partnership between the two biggest carbon emitters in the world.

Scenario planning has a long history. The RAND Corporation employed it heavily in planning for potential U.S. responses to nuclear war and 16^th century Spanish Jesuit theologians pointed to the idea as proof of free will. But in many respects this powerful set of methodological tools for managing complexity and uncertainty remains underused, especially beyond the defense, intelligence, and business communities.

As Pope Francis gets into high gear on his visit to the United States, it’s worth reviewing details and contexts in the extraordinary message to Catholics and the rest of the planet in “On Care for Our Common Home,” the encyclical he issued earlier this year.

The board of the United Nations’ lead organization on trade and development, called UNCTAD, released an assessment of Gaza’s development challenges during their annual meeting in Geneva this month and the news is not good. In 2012, the UN warned that a “herculean” development effort would be to keep pace with Gaza’s rapid population growth. Since then, more fighting with Israel has made things worse, particularly with regard to water and food security. Ninety-five percent of the water from Gaza’s coastal aquifer is unsafe for drinking without treatment, the report says. Contamination and over-extraction may even render it unusable by next year and damage may be irreversible if not addressed in the next five years.

In the long term, improving maternal and child health is as critical to national security as any problem in Pakistan today, said a panel of experts including Minister of National Health Services Saira Afzal Tarar at the Wilson Center on September 9.
