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.

When we think about countries on the Indian subcontinent with destabilizing demographics, Pakistan comes to mind immediately. First, it’s a country with a very young population. Almost two thirds of its nearly 200 million people are under 25, and the median age is about 22. Second, this youth cohort is highly susceptible to radicalization. Nearly every terrorist attack in Pakistan since 9/11 has been perpetrated by someone under 30. In recent years, the Wilson Center has focused on Pakistan’s youth demographic challenges in detail. India, however, needs to be included in this conversation as well.

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.

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.

In a study published in Science Advances, Mesfin M. Mekonnen and Arjen Y. Hoekstra estimate that over 4 billion people, approximately two-thirds of the world’s population, face severe water scarcity for at least one month out of the year – far greater than previous estimates of between 1.7 billion and 3.1 billion. The authors examined global water scarcity data from 1996 to 2005 on a monthly basis and at a more localized resolution to show how water scarcity affects different places at different times of year.
