The Sahel in West Africa is flat and dry. It depends for much of its water on the Fouta Djallon Highlands, a set of plateaus ranging in elevation from 500-1,500 metres concentrated in central Guinea.

The Highlands are the source of six major rivers flowing into neighbouring countries, and support a rich diversity of ecosystems including savanna, dry forest, and freshwater ecosystems.

The oceans are alarmingly unhealthy and getting sicker fast. At first, crises were localised, as in the collapse of Newfoundland cod and the lifeless dead zone in the Baltic Sea due to runoff of agricultural waste. Now the problems are global.

Mohamed Ismail Yasin, originally from Mayle village in northeast Somalia, fled the region’s prolonged and severe drought with his six-member family and most of his livestock.

They had to travel 600km to the nearest dependable water source: a sand dam near Bandarbeyla in neighbouring Bari region.

Mohamed is one of 615,000 people currently displaced by the drought in Somalia.

Although the heavy seasonal rains have finally started, the long drought has already caused massive displacement and devastated herds.

At first glance, the Dzedokha village, located in the south-west of Bhutan might not seem to have the makings of a lucrative industry.

“I have lived here in these mountains for my whole life. Like my father, and his father before him, I am a herdsman and I graze my animals here in the Toolaylyg and Barlyk River valleys… Herding is the only lifestyle we know. Our animals provide us with our food, clothes, yurts, and fuel for cold winter nights. They are also our main source of income – without livestock, it would be impossible to survive here. So, when our flocks and herds are doing well, we are happy and confident.

Los bifenilos policlorados, o BPC, integraban la lista original de sustancias químicas conocidas como la "docena sucia" que son controladas por el Convenio de Estocolmo, un tratado internacional en materia ambiental cuyo objetivo es eliminar o restringir la producción y el uso de contaminantes orgánicos persistentes (COP). Si bien la producción de BPC se detuvo hace mucho tiempo, estas sustancias se siguen utilizando en sistemas de generación y transmisión de energía eléctrica hasta el día de hoy.
