If these numbers seem daunting, the researchers write that in fact it's a wise investment. The total costs are only about 1-4 percent of the total value of ecosystem services that are lost each year due to environmental destruction, a number estimated at $2.6 to 6 trillion. 'Ecosystem services' include a wide variety of benefits provided by the natural world that doesn't often show up on balance sheets, such as pollination, soil health, seed dispersal, water filtration, air purification, and tourism among many others.
"More prosaically," the scientists add, "the total required is less than 20 percent of annual global consumer spending on soft drinks."
The study has been released in conjunction with a UN meeting in Hyderabad, India for the Convention on Biological Diversity (CBD). The CBD has pledged to stem the loss of the world's biodiversity as well as increase protected areas worldwide by 2020. One of the main issues at the meeting is the dearth of funding for biodiversity.
A coalition of conservation groups--Conservation International (CI), BirdLife International and The Nature Conservancy (TNC)--have asked world leaders to commit to increasing global conservation funding from around $5 billion now annually to $48 billion by 2020.
"The total sums may sound large but much could be achieved through redirecting current investments," says Carolina Hazin, Global Biodiversity Policy Coordinator at BirdLife International. "Reforming perverse and harmful subsidies such as those that stimulate overfishing, deforestation, destructive agricultural practices and the use of fossil fuels, could contribute significantly to the sustainable use of natural resources and halting biodiversity loss."
However, according to the study's findings $48 billion a year may be too little yet.
To determine the costs of total biodiversity coverage, researchers estimated how much it would cost to save 211 threatened birds (or 19 percent of known bird species) on the IUCN Red List, and then extrapolated their findings to cover all other imperiled species, including non-birds. Similarly they estimated per hectare costs for managing 396 conservation in 50 countries and then extrapolated the costs to the protected area goals set by the CBD, i.e. expanding protected areas to 17 percent of the world's land area and 10 percent of oceans by 2020. The final tally: at most $80.86 billion a year.
According to the study, conservation of the world's biodiversity is woefully underfunded. Direct conservation funding was found to be too low by 88 percent for the birds included in the study. Perhaps, even more alarming most of the money went to just a few species, leaving many imperiled birds with pittance or nothing at all. For example, only seven of the 211 birds surveyed had funding that reached levels of 90 percent.
The study also found that protected areas are currently underfunded by 69 percent in lower-income countries and 50 percent in higher-income countries. Lack of funding for protected areas can translate into areas rife with illegal logging, mining, poaching, and encroachment; some parks have become practically empty of medium to large-sized animals, others have lost much of their forest.
"Meeting [the CBD] targets will require conservation funding to increase by at least an order of magnitude," the study concluded.
Teetering on the edge: the world's 100 most endangered species (photos)
(09/10/2012) From the Baishan fir (five left in the world) to the Sumatran rhino (around 250), a new report highlights the world's top 100 most endangered species, according to the the International Union for Conservation of Nature (IUCN) and the Zoological Society of London (ZSL). The list spans the taxonomic gamut, from fungi (Cryptomyces maximus) to amphibians (the Table Mountain ghost frog) to flowers (the Cayman Islands ghost orchid) and much more (see full list at the end of the article).
One extinction leads to another...and another
(08/28/2012) A new study in Biology Letters demonstrates that altering the relationship between a predator and its prey can cause wide-ranging ripple effects through an ecosystem, including unexpected extinctions. Species help each other, directly or indirectly, which scientists refer to as mutualism or commensalism. For example, a species’ success may rely not only upon the survival of its food source, but may also indirectly rely upon the survival of more distantly related species.
Recommendations to save India's Western Ghats creates political stir
(08/20/2012) A massive expert panel report on the conservation of the Western Ghats has caused a political stir in India. The report, headed by noted ecologist Madhav Gadgil, recommends that the government phase out mining projects, cancel damaging hydroelectric projects, and move toward organic agriculture in ecologically-sensitive sections of the Ghats. The report, which was leaked after the government refused to release it, has yet to be implemented. Recently dubbed a UNESCO World Heritage Site, the Western Ghats is one of India's largest wildernesses and home to thousands of species, many found no-where else.
North American freshwater fish going extinct at rate over 800 times the fossil record
(08/14/2012) Since 1898 North America has lost at least 39 species of freshwater fish, according to a new study in Bioscience, and an additional 18 subspecies. Moreover, the loss of freshwater fish on the continent seems to be increasing, as the rate jumped by 25 percent since 1989, though even this data may be low.
Half of tropical forest parks losing biodiversity
(07/25/2012) Governments have set up protected areas, in part, to act as reservoirs for our Earth's stunning biodiversity; no where is this more true than in the world's tropical forests, which contain around half of our planet's species. However a new study in Nature finds that wildlife in many of the world's rainforest parks remains imperiled by human pressures both inside and outside the reserves, threatening to undercut global conservation efforts. Looking at a representative 60 protected areas across 36 tropical nations, the scientists found that about half the parks suffered an "erosion of biodiversity" over the last 20-30 years.
