It might seem strange to say that the deep sea, the vast expanse of the world’s oceans beyond the continental shelf, is at risk of conflict and competition. After all, no one lives there, and as is often said, more is known about the surface of the moon than most parts of the ocean floor. But the fact is, even the cold, dark reaches of the ocean are no longer immune to resource competition between the world’s major powers.

Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped from an intake a mile offshore.

The idea that climate change is causing migration and displacement is entering the mainstream, but experts have warned against using the term “climate refugees” to describe what we’re seeing in small islands, coastal regions, and even conflict zones like Syria.

What is just was the subject of our top three most popular stories last month on New Security Beat. From climate policy to gender inequality, many governments and NGOs are grappling with how to address marginalization and other systemic problems through interventions that also address environment or health issues. As the Sustainable Development Goals encourage such integrated thinking – by rich and poor countries – these kinds of considerations are likely here to stay.

Times are good for Fey Wei Dong. A genial, middle-aged businessman based in Hangzhou, Fey says he is raking in the equivalent of $225,000 a year from trading in the humblest of commodities: sand.

Overfishing by foreign fleets in West Africa is leading to devastating social and economic consequences. In a report from the Overseas Development Institute, an independent think tank based in London, researchers use satellite data to assess the scale of two kinds of illegal, unreported, and unregulated fishing: “reefers,” or large-scale commercial vessels receiving and freezing fish at sea and at port, and large refrigerated container ships that are registered in countries with less stringent enforcement regulations than that of the ship’s owners.

The once-every-three-years Women Deliver conference has become a major coalescing force for various global health and development efforts aimed at women and girls. “We operate at a global level, influencing the agenda” by focusing on the “four Cs”: convening, communicating, capacity-building, and catalyzing, said Susan Papp, director of policy and advocacy for Women Deliver. [Video Below]

One of the findings of the Worldwatch Institute’s Family Planning and Environmental Sustainability Assessment (FPESA) suggests it’s not accurate to claim that climate change is at the root of growing water scarcity around the world. Based on the best recent scientific evidence we could find, another major global trend – the ongoing growth of human population – has a greater impact on water availability than climate change does.
