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.

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.

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.

DURBAN, South Africa — Arguably the most elegant aspect of an inelegant subject is how this city of 3.2 million residents, South Africa’s second largest, is solving monumental water and waste challenges in its jammed informal settlements.
