It’s hard to imagine today, but Kabul was once ringed with grassy areas and shrubs, a few trees in areas too. Some of my husband’s favorite recollections of early 1970s Afghanistan are of simple family picnics in picturesque parks. Hours of lounging, grilling kebab, preparing rice, and conversing were a respite from the oppressive heat of the capital. Sometimes a picnic would become an all-night, extended family gathering. The Gardens of Paghman were a favorite destination with rows of pine trees, roses, and cool fountains. Pre-war family photos reveal neatly trimmed trees, bushes, and ample grassy areas for impromptu games. The family picnic is still popular among the Afghan diaspora. In the United States, Afghan community events are often held in parks, and involve large, multi-family picnics.

A study published by the Proceedings of the National Academy of Sciences projects future sea-level rise with a new model, providing crucial information for coastal planning and further impetus to cut carbon emissions. Sifting through data on thermal expansion and retreating glaciers, the two leading causes of sea-level rise in the past century, the authors confirm that sea level is rising at an unprecedented rate.

The climate agreement reached in Paris last December, seen by many as a critical step toward lowering greenhouse gas emissions, was big news – perhaps too big. Pointing to the thousands of articles about COP-21, National Geographic Senior Editor Marla Cone asked at a recent Wilson Center panel, “Is this a wise use of resources, when newsrooms are so stretched thin, to have everybody pretty much chasing the same stories?”

A four-part video series produced by the Kenya Broadcasting Corporation (KBC) and supported by the Fund for Investigative Journalism gives an update on the beleaguered communities of Lake Turkana, the world’s largest desert lake that supplies vital ecosystem services and livelihoods to 300,000 people in northwestern Kenya. The lake is fed entirely by the Omo River, flowing south from Ethiopia, but a newly completed upstream dam has raised questions about the future.

Migration is an important strategy for coping with environmental variability and change, but it can also place additional stress on ecosystems. Policymakers and practitioners are not always fully aware of these threats, nor fully prepared to manage them through appropriate interventions. Conservation professionals in the field therefore have a key role to play in reducing the harmful impacts that migration can have on the environment, and in mitigating any tensions that may emerge between migrant and host communities.

The year is 2022. Strong El Niño and La Niña events in successive years have drastically reduced wheat yields in India and Australia and increased the range of certain pests and plant pathogens in the Western Hemisphere. Moreover, a drought across North America has reduced corn and soybean yields significantly. Global commodity prices are up 262 percent over long-term averages. These price increases are compounding other social and economic challenges, contributing to social unrest in several food-importing nations.

This fall, the National Intelligence Council released an intelligence community assessment of the extent to which factors such as climate change, severe weather, conflict, resource scarcity, disease, poor governance, and environmental degradation will impact peoples’ purchasing power and food availability over the next decade. They found “the overall risk of food insecurity in many countries of strategic importance to the United States will increase.”
