Google Earth Shows How Dams Could Worsen Climate Change

A new interactive Google Earth video, produced by International Rivers and Friends of the Earth International, aims to show how damming rivers around the world can exacerbate climate change.

The approximately 12-minute video uses computer animation to simulate the potential climate hazards associated with building dams in Africa, the Himalayas, and the Amazon.

Blue Harvest: Inland Fisheries as an Ecosystem Service

Abstract: 

Damming a river may bring electric power, but it often comes at the price of high-quality food fisheries, experts say. When dams are proposed for power, flood control or irrigation, the often devastating impacts on fisheries in rivers and lakes are ignored or discounted.This report by the UN Environment Programme (UNEP) and the World Fish Centre warns that despite over 40 years of steady production globally, rapid environmental changes are occurring which challenge the viability of future fish stocks and a range of internationally- agreed development targets including the Millennium Development Goals.The report is available online at http://www.unep.org/pdf/Blue_Harvest.pdf

Integrating Environmental Flows into Hydropower Dam Planning, Design, and Operations

Water Working Notes
Volume: 
22
Year: 
2009
Abstract: 

This Technical Guidance Note was primarily prepared as a contribution to the World Bank economic and sector work—mainstreaming environmental flow requirements into water resources investments and policy reforms jointly supported by the Environment Department and the Energy, Transport and Water Department. The technical note also forms a contribution to the Bank’s hydropower investments. The main objective of the note is to serve as a guidance document as opposed to a technical manual. It has been developed to assist World Bank staff and their clients to identify ways to better incorporate the benefits associated with environmental flow protection into hydropower dam projects.Most of the material in this note will be equally applicable to hydropower dams with either multiple objectives or a single objective, but the integration of environmental flow protection into projects with multiple objectives presents some special challenges. In addition, many issues covered in this note will be applicable to other types of water infrastructure projects.
