Invasive species date back thousands of years

(10/13/2005) Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time? Luiz Rocha leads geneticists who time travel through ocean environments. The results of their travels, published online in Molecular Ecology, tell us that during warm, interglacial periods, reef-associated fish (goby genus Gnatholepis), leapt around the horn of Africa into the Atlantic, where their range expanded as the world warmed.

Africa Heats Up -- climate change threatens future of the continent

(10/11/2005) A series of recent studies have revealed a sobering future for the majority of Africa, a future predicated by undeniable and significant climate change. The threat traverses all levels of the environmental, social, political and economic spheres, from heightened socio-economic disparity to dwindling fish populations, from civil strife to desperate hunger. The greatest and saddest irony of this dark fate projected for the continent is that while Africa has the world's lowest levels of carbon dioxide and other greenhouse gas emissions, contributing the least to global climate change, it has been forced to bear the brunt of the phenomenon.

Harvesting tornados as power plants; renewable wind vortex energy

(10/09/2005) Engineers are working to use artificial tornados as a renewable energy source according to an article in last week's The Economist. Storms release a tremendous amount of energy. Hurricane Katrina, a category 4 hurricane, released enough energy to supply the world's power needs for a year, while the typical tornado produces as much power as a large power station.

Environment killing millions says World Bank report

(10/07/2005) A new report from the World Bank says millions of deaths can be attributed to environmental factors, including climate change, pollution, unsafe water, poor sanitation and hygiene. These environmental conditions are significantly affecting health -- responsible for about a fifth of all ill health in poor countries -- and impeding economic development and growth. The report also links cancer to the environment.

Now identified as likely origin of SARS; will bats be killed in China?

(09/29/2005) The likely source of the respiratory disease SARS is the horseshoe bat, a new study in the journal Science suggests. Researchers found a virus closely related to the SARS coronavirus in bats from three regions of China. The 2003 SARS outbreak killed 770 people and caused billions in economic damaged.

First megatransect of Madagascar completed

(09/27/2005) Late last year an international team completed the first known transect of the island of Madagascar, the world's fourth largest island. The eight-month-long journey, dubbed "Hike Madagascar," took the group of intrepid hikers from the southern tip of Madagascar to the northernmost point of the island. The transect targeted rural communities along the eastern forest corridor, surveying villages and providing local farmers with techniques for improving rice yields and putting more food on the table for their families. The hike also provided a glimpse into some of the socioeconomic and environmental issues facing the island nation, which is one of the poorest in the world.

Danish researchers develop hydrogen tablet that stores hydrogen in inexpensive and safe material

(09/21/2005) Scientists at the Technical University of Denmark have invented a technology which may be an important step towards the hydrogen economy: a hydrogen tablet that effectively stores hydrogen in an inexpensive and safe material. With the new hydrogen tablet, it becomes much simpler to use the environmentally-friendly energy of hydrogen. Hydrogen is a non-polluting fuel, but since it is a light gas it occupies too much volume, and it is flammable. Consequently, effective and safe storage of hydrogen has challenged researchers world-wide for almost three decades. At the Technical University of Denmark, DTU, an interdisciplinary team has developed a hydrogen tablet which enables storage and transport of hydrogen in solid form.

Builder of rainforest canopy walkways believes conservation can be profitable

(09/20/2005) This month's issue of The Ecological Finance Review details Greenheart conservation Company, a for-profit company that designs, builds and operates conservation based canopy walkways (canopy trails) and other nature-based attractions around the world. Operating on the premise that conservation can be economically viable, Greenheart believes that is has already become a "model of how to shift gears from an industrial to a green economy." Greenheart has developed or is developing canopy walkways in Peru, Nigeria, Madagascar, Ghana, Brazil, Guyana, the United Kingdon, and Canada.

Cost of Iraq War to top $1.25 trillion says academic

(09/20/2005) The total cost of the Iraq War for the UK, the USA, Iraq and other nations is likely to top US$1.25 trillion dollars according to Keith Hartley, a professor at the University of York's Center for Defence Economics.

90% of largest companies concerned about climate change

(09/18/2005) More U.S. corporations than ever before now factor climate change into the risks and opportunities faced by their businesses, according to a report released today by the Carbon Disclosure Project, a coalition of institutional investors with more than $21 trillion in assets. Increased interest from the investment community, in conjunction with related macro-economic developments, is encouraging the development of strategies to reduce greenhouse gas emissions.

Economic impact of hurricane close to neutral

(09/07/2005) The CBO projects 400,000 people will be unemployed due to Hurricane Katrina. Further, the hurricane is unlikely to have much impact on overall economic growth in the United States. Generally, the overall impact of natural disasters is often close to neutral since lost output from destruction and displacement is then compensated for by a big increase in reconstruction and public spending.

Forest fires have serious economic and health consequences warns FAO

(09/05/2005) Large forest fires in South-East Asia, notably in Indonesia, have caused serious health and environmental problems, in particular choking haze in the region, FAO said today.

Plan to move African wildlife to America would undermine ecotourism and African economies

Poor need renewable energy sources says Annan

(08/23/2005) In a new report, United Nations Secretary-General Kofi Annan says energy poverty is seriously impeding socio-economic development in the world's poorest countries. Noting that in the developing countries some 1.6 billion people still lack access to electricity and about 2.4 billion continue to rely on traditional biomass like fuelwood for cooking and heating, Annan calls for intensified efforts to promote renewable energy sources for the poor.

Summit explores how fish could feed Africa

(08/22/2005) This week policy makers, industry leaders, and development experts are meeting in Abuja, Nigeria to discuss the future of African fisheries and aquaculture. The fisheries sector, consisting of both inland (freshwater) and marine fisheries, is a vital source of food and income to millions of Africans. Fish production, processing and trade provides employment for more than 10 million, while fish exports from Africa are worth US$ 2.7 billion annually. The following is a description of the summit from Fish for All, an initiative seeking to shape public policy on issues from issues as fish and development, fish and nutrition, health, livelihood, environment, gender, water, river basins and coasts, trade and economic growth.

Farming the world's largest fish - an alternative to deforestation

(05/19/2005) Integrated aquaculture offers great potential for sustainable poverty allievation in the Amazon region. It reduces the need to clear land for subsistence agriculture while generating significant economic and nutritional benefits for poor Amazonian colonists.

Cultivated forests play important economic and ecological role in Indonesia

(05/17/2005) Old growth tropical forests are valuable and irreplaceable ecosystems that house the majority of Earth's known terrestrial biological diversity. While these forests are rapidly disappearing, they are not necessarily being completely cleared without replacement. In some regions, primary forests are being replaced with "cultivated forests" or "forest gardens," where useful trees are planted on farmlands after the removal of pre-existing natural forests. A new report Domesticating forests: How farmers manage forest resources by Genevieve Michon explores the characteristics and implications of these forests in Indonesia.

Ford Shareholders Criticize Automaker's Economic and Environmental Performance

(05/12/2005) Emphasis on Gas Guzzlers has put the company at risk. Shareholders ask Ford's Directors to align executive compensation and lobbying policies with increased gas mileage.

In Madagascar, Woodworking Zafimaniry remember lost forests

(05/12/2005) In the rolling hills of the southeastern highlands of Madagascar there lives a group of people known as the Zafimaniry, or the "the people of the forest." The Zafimaniry are renowned sculptors of wood and traditionally, virtually every member of the community was involved in some aspect of woodworking and cabinetmaking. However, these are not good times for many Zafimaniry. Severe deforestation for slash-and-burn cultivation ("tavy") has left their surroundings nearly completely devoid of trees. Once encircled by vigorous forests, some Zafimaniry villages are more than a day's trek from the nearest natural wood source. As a result, over the past decade, the Zafimaniry have increasingly looked toward tourism as an answer to their the economic plight. The unmoderated flow of tourists into these remote and delicate communities has denigrated their culture and left some Zafimaniry further entrenched in poverty.

For What It's Worth: Ecological Services and conservation

(05/04/2005) For a long time, preserving natural spaces was considered to be a favor to the environment without a true, measurable benefit to businesses, industrial production and productivity. In recent years however, scientists are increasingly producing substantial evidence to support the notion that the natural environment supplies a diverse range of renewable economic benefits beyond timber and fish. These benefits are termed “ecological services” and provide such valuable functions as water treatment, pollination and sediment capture, simply by remaining intact.

Madagascar looks toward a brighter economic future with movie, new aid package

(04/18/2005) While the planet's most biologically diverse island is also one of the poorest countries in the world, Madagascar may well be on its way to a brighter economic future thanks to a blockbuster animated movie, an innovative new aid program, and the capable leadership of the new president.
