Fish are increasingly threatened by the effects of climate change as temperatures rise in rivers, lakes and oceans, says a new WWF report. It says that hotter water means less food, less offspring and even less oxygen for marine and freshwater fish populations. Meanwhile, a researcher in Australia said that freshwater ecosystems in that country will be threatened as much by the human response to climate change as by climate change itself.
A study released in late October shows that areas buffered by coastal forests, like mangroves, were less damaged by the 2004 tsunami than areas without tree vegetation. Last week the FAO reported that 20% of the world's mangrove forests have disappeared since 1980.

Revised deforestation figures from FAO show that Nigeria, not Cambodia, suffered the highest rate of forest loss between 2000 and 2005. During that period, the West African country lost 55.7 percent of its primary forests, mostly due to logging, fuelwood collection, and subsistence agriculture. FAO gave no reason for the revision.
Climate climate will result in costly disruptions to water supply and resource management systems according to new research by scientists at UCSD, the University of Washington, and USGS. The simulations, presented in Nature predict increased water runoff in eastern equatorial Africa, the La Plata basin and high latitude North America and Eurasia. They forecast declining water availability in southern Africa, southern Europe, the Middle East and mid-latitude western North America. Yesterday Kofi Annan, Secretary-General of the United Nations, unveiled a prototype of a cheap and rugged $100 laptop for children, as part of the UN's goal of giving poor communities access to the benefits of information technologies and networks.

The Food and Agriculture Organization of the United Nations has issued a response to a study that found selective logging in the Amazon is highly destructive. The research, conducted by scientists from the Carnegie Institution at Stanford University, was published in Science last month. FAO argues that selective logging is not necessarily destructive and can be done with low impact on the remaining forests, if the proper techniques are applied.
Financial institutions are buying up millions of acres of forest land for development across the United States, New Zealand, and South America according to an article in The Wall Street Journal. Since 1994, nearly $30 billion of American forest land has come under control of financial investors, a six-fold increase. Environmental implications of the land transfer may prove significant.

Ebay Inc. founder Pierre Omidyar and his wife, Pamela, have given $100 million in eBay stock to Tufts University to create a fund that will invest in microfinance. Microfinance, the practice of loaning small amounts of money to people who are often too poor to qualify for conventional lending, is increasingly seen as a promising means to help the world's poorest people. Supporters argue that microfinance can fund microenterprises that generate broad-based, long-term economic growth opportunities in developing countries.

The economic benefits of protecting a rainforest reserve outweigh the costs of preserving it says a new study published in Proceedings of the National Academy of Sciences. A cost-benefit analysis of Mabira Forest Reserve in southern Uganda found that rainforest conservation was economically viable despite intense pressures to exploit the forest for timber harvesting, fuelwood, charcoal production, and agricultural development. The research suggests rainforest parks can play an important economic role in rural communities.

Research released earlier this month in Science found that Brazil's Amazon rain forest is being degraded twice as fast as deforestation figures suggest. Selective logging, where only one or two valuable tree species are harvested from an area, is driving the forest degradation. The findings have important implications for "sustainable harvesting" schemes that have been promoted as ecologically-sound alternatives to traditional harvesting techniques.
