UN Report finds that Biodiversity continues to decline at alarming rates
May 11th, 2010
Global Biodiversity Outlook 3
Today marks the launch of the third edition of the Global Biodiversity Outlook (GBO-3, hereafter referred to as the Outlook). This much anticipated flagship publication of the Convention on Biological Diversity (CBD) is the product of close collaboration between the Secretariat of the CBD and the United Nations Environment Program-World Conservation Monitoring Center (UNEP-WCMC). The Outlook, an assessment of the current state of biodiversity, is being launched simultaneously in a multitude of cities across the globe. The report is based on scientific assessments, national reports submitted by governments and a study on future scenarios for biodiversity. The report, which is subject to an extensive independent scientific review process, is one of the principal milestones of the 2010 International Year of Biodiversity. Sadly, coming right on the heels of the BP gulf spill disaster, the report does not deliver good news. According to the report, world leaders have failed to deliver on commitments made in 2002 to reduce the global rate of biodiversity loss by 2010, and have instead overseen alarming biodiversity declines. In the preface to the report, Executive-Secretary of the CBD, Ahmed Djoghlaf laments “No country has reported that it will completely meet the 2010 target, and a few Parties have unequivocally stated they will not meet it.”
The Outlook warns that massive further loss of biodiversity is becoming increasingly likely, and with it, a severe reduction of many essential services to human societies as several “tipping points” are approached, in which ecosystems shift to alternative, less productive states from which it may be difficult or impossible to recover. Some of tipping points analyzed in the report include;

Brazilian Deforestation (UNEP-WCMC)
- The dieback of large areas of the Amazon forest, due to the interactions of climate change, deforestation and fires, with consequences for the global climate, regional rainfall and widespread species extinctions.
- The shift of many freshwater lakes and other inland water bodies to eutrophic or algae-dominated states, caused by the buildup of nutrients and leading to widespread fish kills and loss of recreational amenities.
- Multiple collapses of coral reef ecosystems, due to a combination of ocean acidification, warmer water leading to bleaching, overfishing and nutrient pollution; and threatening the livelihoods of hundreds of millions of species directly dependent on coral reef resources.

Bleaching Reef Systems (UNEP-WCMC)
On a positive note, the report does see progress in the creation of preserves, in particular in the number of protected marine areas announced in recent months, but the overall assessment of the Outlook warns that habitat losses have offset gains. Wetlands, salt marshes and habitats for shellfish seem to be suffering the most damage. The report notes that “the abundance of vertebrate species, based on assessed populations, fell by nearly a third on average between 1970 and 2006 and continues to fall globally”. The driving causes behind biodiversity loss (habitat change, overexploitation, pollution, invasive alien species and climate change) are either constant or increasing in intensity, the Outlook finds. Nutrients washing off farmland are turning waterways into biological “dead zones,” the report says, and ocean acidification and stormwater runoff have made coral reefs “vulnerable to collapse.” The report also sounds the alarm on overfishing, an area where government regulation has been particularly lax and which now threatens the impending collapse of important commercial fish stocks.

Disappearing Amphibians (UNEP-WCMC)
In a press release issued yesterday by the UNEP- WCMC, Djoghlaf warned “the assessment of the state of the world’s biodiversity in 2010 should serve as a wake-up call for humanity. Business as usual is no longer an option if we are to avoid irreversible damage to the life-support systems of our planet.” The Outlook points out that for a fraction of the money summoned up instantly by the world’s governments in 2008-9 to avoid economic meltdown, world governments could avoid a much more serious and fundamental breakdown in the Earth’s life support systems. UN Under-Secretary-General and Executive Director of the United Nations Environment Program, Achim Steiner, notes that there have been key economic reasons why the 2010 biodiversity targets were not met. “Many economies remain blind to the huge value of the diversity of animals, plants and other life-forms and their role in healthy and functioning ecosystems from forests and freshwaters to soils, oceans and even the atmosphere. Many countries are beginning to factor natural capital into some areas of economic and social life with important returns, but this needs rapid and sustained scaling-up.” observes Mr. Steiner.

Desertification (Reeza, United Nations Convention to Comabt Desertification)
The report ultimately states that “New Vision” is required to address the continued dramatic decline of species biodiversity. In the forward to GBO-3, the United Nations Secretary-General, Ban Ki-Moon writes: “To tackle the root causes of biodiversity loss, we must give it higher priority in all areas of decision making and in all economic sectors.” Djoghlaf urges that “the CBD’s new Strategic Plan, to be adopted at the 2010 Nagoya Biodiversity Summit, must tackle the underlying causes of biodiversity loss. The linked challenges of biodiversity loss and climate change must be addressed with equal priority and close cooperation. Joint action is needed to implement the Conventions on Biodiversity, Climate Change and to Combat Desertification – the three conventions born of the 1992 Rio Conference.” Djoghlaf believes that this weeks’ (May, 15) Rio+20 summit in New York will provide an ideal staging ground to lay groundwork for this new strategic approach.
The Outlook will also be a key input into discussions by world leaders and Heads of State at a special high level segment of the United Nations General Assembly on September, 22. Its conclusions will also be central to the negotiations by world governments at the Nagoya, Japan Biodiversity Summit in October of this year.
