“Climate change is one of the greatest challenges that we are facing in today’s world; it is particularly important for us in the Caribbean and for a country like Trinidad and Tobago,” says ECSP Director and Trinidad-native Roger-Mark De Souza in an upcoming documentary by Sustain T&T, a non-profit based in the islands.

The disastrous flooding in the Himalayan state of Uttarakhand this summer, which claimed more than 6,000 lives, was the outcome of a changing climate and poorly planned development. It was also another case in point of the increasing importance of environmental security in India – especially for the military.

The black, blasted landscape of Wuhai City sometimes looks more like the moon than Inner Mongolia. But this scene is becoming all too common across much of Northern China. China’s massive coal industry is not only polluting the air and water, but also fundamentally altering the surrounding landscape and communities.

To use the military parlance, climate change is often considered a “threat multiplier,” challenging stability and development around the world by exacerbating underlying conditions of vulnerability. South Asia is one region that faces multiple stressors that have the potential to feedback off each other.

Higher temperatures, more extreme weather, rising sea levels, flooding, and increased cyclonic activity in the Bay of Bengal and the Arabian Sea are reshaping the environment, warns the Center for American Progress (CAP) in a report.

Earth’s climate is changing, whether you like it or not. As it does, other changes – like rising sea levels or falling crop yields – follow. It is easy to see how this might lead to conflict. Competition for ever scarcer resources such as arable land and its bounty can turn ugly. As the price of food rises the poor, who spend more of their income on it, are hit more than the rich, exacerbating income inequality and leading to disaffection, resentment and, possibly, violence.

Water, energy, and food – this “nexus” of interrelated resource issues continues to garner attention from analysts, policymakers, and the media. Over the next four decades global population is projected to increase to about 9.6 billion and, worldwide, demand for water is projected to increase 55 percent; energy, 80 percent; and food, 60 percent. In a new video about the first of a series of workshops on this nexus, the International Union for Conservation on Nature and the International Water Association explain how they are working to bring together private and public sector water infrastructure experts from across Africa and the world to build partnerships and create some consensus on a “nexus-based approach” to managing scarce resources.

During the Gezi Park protests last month in Istanbul, Turks and Kurds dismissed historical mistrust and banded together against Prime Minister Erdogan’s growing authoritarianism. Some have suggested the newly unifying cause has strengthened momentum for a long-standing solution to Kurdish autonomy and rights in Turkey. Still it may be water that the fate of Kurdish ambitions is most tied to, rather than officials in Ankara or protestors in Istanbul.
