Two proposed hydroelectric dams in Bolivia are set to create a serious socio-ecological calamity. They are emblematic of the injustices that have been a consistent feature of the Morales government. JONATHAN ELWELL investigates
Controversial plans have been proposed to build thousands of dams in the Balkans. Campaigners fear they will destroy protected areas and national parkland. ALESSIO PERRONE reports on the issue and on the NGOs fighting to save the 'blue heart of Europe'
Longer than England, almost as deep as the Grand Canyon, Russia's Lake Baikal is one of the world's greatest aquatic wonders, writes Bryce Stewart. But it's a fragile paradise: the limpid waters are warming much faster than the global average, with as yet unknown effects on its ecology. And it faces the danger of a huge dam on its principal tributary, Mongolia's Selenga River.
Without water to feed its hydroelectric dams, drought-hit Brazil is turning to solar power - dubbed 'a fantasy' by the country's president just a few years ago, writes Jan Rocha. Now thousands of megawatts of floating solar panel 'islands' are to be installed on dam reservoirs.
Over 18 million people live off the natural bounty of the The Mekong Delta, writes Tom Fawthrop - the source of huge annual harvests of fish, rice, fruit, and one of the world's most productive ecosystems. But now huge dams threaten to strangle the Mekong river and the abundant life it supports, while the world sits idly by.
Since the 1980s Cambodia has lost 84% of its primary forests, and the remote Cardamom mountains are the country's last great natural treasure, writes Rod Harbinson. Just the place for grandiose dam projects? 'No way!" say indigenous people and young eco-activists.
Massive dams in Sarawak, Malaysia, threaten to flood over 2,000 square kilometers of the world's oldest rainforests, displace 10,000s of indigenous people, and aggravate climate change, writes Amanda Stephenson - all to generate electricity that no one wants.
India is in the grips of a state-backed corporate war against the environment, the poor and indigenous peoples, writes Graham Peebles. The new rulers avert their gaze as their countrymen, doused in poverty, burn on the party pyre.
Supporters of a controversial dam in one of Asia's poorest countries say it will bring huge economic benefits. Critics say it could threaten fisheries and rice cultivation, threatening the livelihoods of millions. Brendan Brady reports from Laos
The Severn Estuary, earmarked as a potentially huge source of energy, has been met with increasing concerns over serious environmental damage. A report from 2008 by Frontier Economics found that justification for the Severn Barrage is slim - both economically speaking and on environmental grounds. Peter Bunyard takes a look at an innovative solution that has similarities with a tidal reef.
The pesticide industry knows all too well that nature quickly develops immunity to its chemical armoury. But a new study by scientists at the Instituto Gulbenkian de Ciencia (IGC) and the Faculty of Science of the University of Lisbon, in Portugal has shown that a species of worm can develop resistance to a common pesticide in just 20 generations, or 80 days.
