Animal pollinators responsible for 35 percent of world food crop

(10/25/2006) A new study calculates that 35 percent of the world's crop production is dependent on pollinators, like bats, bees, and birds. The research suggests that biodiversity loss could directly impact global food crops.

Biodiversity extinction crisis will disrupt important ecological services warns study

(10/25/2006) Loss of biodiversity will have an ecologically-costly impact according to a study published in the journal Nature this week. The new study, headed by a biologist at the University of California, Santa Barbara (UCSB), found that species extinction will reduce nature's ability to maintain ecological balance and "services" such as water filtration, nutrient cycling, and pollination.

Global Warming Threatens Pollination Timing

(08/09/2006) In addition to the more obvious effects of climate change, such as rising sea levels and increasing storm activity, there is the potential to dramatically alter ecological communities. Dr. David Inouye, director of University of Maryland's graduate program in Sustainable Development and conservation Biology, reports that global warming could disrupt the timing of pollination in alpine environments, with serious negative impacts to both plants and pollinators.

Bees and flowers disappearing together

(07/23/2006) The diversity of bees and of the flowers they pollinate, has declined significantly in Britain and the Netherlands over the last 25 years according to research led by the University of Leeds and published in Science this Friday (21 July 2006). The paper is the first evidence of a widespread decline in bee diversity.

Insects worth $57 billion to US economy

(04/01/2006) A new study says insects are worth at least $57 billion to the American economy. In the April 2006 issue of BioScience, John E. Losey of Cornell University and Mace Vaughan of the Xerces Society for Invertebrate conservation estimate the value of ecological services provided by insects. Looking at just four services--dung burial, control of crop pests, pollination, and wildlife nutrition--Losey and Vaughan calculate that the annual value of insects in these roles is at least $57 billion in the United States.

Coral reefs and mangroves have high economic value

(01/24/2006) Protecting coral reefs and mangrove forests makes economic sense according to a new report by the United Nations Environment Programme (UNEP). The report argues that conserving these ecosystems for the services they provide--from fisheries protection to erosion control to a source for medical compounds--is cost-effective relative to destroying them and substituting their role with man-made structures.

Deforestation causes 25% of greenhouse gas emissions

(12/10/2005) Yesterday the Food and Agriculture Organization of the United Nations (FAO) offered to provide forestry data and technical assistance to countries looking to mitigate greenhouse gas emissions through the reduction of forest loss.

Rainforest conservation worth the cost shows new study

(11/02/2005) The economic benefits of protecting a rainforest reserve outweigh the costs of preserving it, says University of Alberta research--the first of its kind to have conducted a cost-benefit analysis on the conservation of species diversity. "The traditional moral and aesthetic arguments have been made about why we should conserve the biodiversity in rainforests, but little has been done that looks at whether it makes pure economic sense to do so," said Dr. Robin Naidoo, who did his PhD at the U of A in biological sciences and rural economy. "We provide some good evidence from a strict economic side, that yes, it does."

Deforestation and erosion starving Malawi

(10/13/2005) Forest loss and erosion could doom Malawi to perpetual food shortages as the country's fertile soil is literally swept down to its rivers and flushed out to sea.

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.

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.
