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.

Patterns of trade and consumption in the global food system are shifting. In the past, most trade in agricultural commodities occurred between developed and developing countries. But, in recent years, the volume of South-to-South trade has increased significantly. Today, some of the most problematic crops in terms of their effect on the environment, such as soy and palm oil, are predominantly traded amongst developing and fast-rising countries.

As a young and promising marine biologist, Camilo Mora led a team of 55 scientists assessing the rapid decline of fish on the world’s coral reefs. It was a global enterprise with broad implications. Hundreds of millions of people rely on reef fish for their primary source of animal protein. Healthy reefs protect coastal communities from devastating storms and provide a multitude of livelihoods, including jobs in the fast-growing tourism industry.

As the UNFCCC Conference of the Parties (COP) gets underway in Paris, #resilience appears with increasing frequency on my Twitter feed, and I frequently hear talk about “socio-ecological resilience,” “climate-resilient development,” and “resilience programming.”

When Colombia is in the news, it’s not necessarily for the reasons we Colombians would like. We have lived through 50 years of violent conflict. Peace is a very abstract idea to most of us. Despite this we are still some of the happiest people on Earth.

The fires that blazed in Indonesia’s rainforests in 1982 and 1983 came as a shock. The logging industry had embarked on a decades-long pillaging of the country’s woodlands, opening up the canopy and drying out the carbon-rich peat soils. Preceded by an unusually long El Niño-related dry season, the forest fires lasted for months, sending vast clouds of smoke across Southeast Asia.

The focus of the global community on the outcomes of the Paris Conference of Parties (COP) to the UN Framework Convention on Climate Change (UNFCCC) in December is unprecedented. The world awaits, anticipating the details of an international and legally-binding agreement to address climate change. [Video Below]

Rashidy Kazeuka says a forest cleared for charcoal is a silent and desolate place. No birds or other wildlife, just a barren, dried out landscape.
