TheMillennium Ecosystem Assessment (MA) is a major assessment of thehuman impact on the environment, called for by the United Nations Secretary-GeneralKofi Annan in 2000, launched in 2001 and published in 2005 with more than $14 million of grants. It popularized the termecosystem services, the benefits gained by humans fromecosystems.

History

[edit]

During the 1990s, international conventions such as the UNEPConvention on Biological Diversity and theConvention to Combat Desertification identified the need for a global scientific ecosystem assessment. There had been advances inresource economics with little effect onenvironmental policy.[1]In November 1998,UNEP,NASA, and theWorld Bank published a study called "Protecting our Planet, Securing our Future: Linkages Among Global Environmental Issues and Human Needs".[1] In 2001, the Millennium Ecosystem Assessment was launched with work over a period of four years.[1] Over 1300 contributors from 95 countries were involved as authors.[2]

Funding

[edit]

In May 2000 theGlobal Environment Facility approved a $7 million grant, followed in July 2000 by aUnited Nations Foundation $4 million grant and financial support from thegovernment of Norway for the first meeting of the Board of the MA inTrondheim, and in December 2000 a $2.4 million grant by thePackard Foundation for a total of more than $13.4 million, considered "75% of the full budget".[1]

Findings

[edit]

The MA was published in 2005 and made four main assessments:[2]

  • Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growingdemands for food, fresh water, timber, fiber and fuel. This has resulted in a substantial and largely irreversible loss in thediversity of life on Earth.
  • The changes to ecosystems have contributed to substantial net gains in humanwell-being andeconomic development, but these gains have been achieved at growing costs in the form of thedegradation of manyecosystem services, increased risks of nonlinear changes, and the exacerbation ofpoverty for some groups of people. These problems, unless addressed, will substantially diminish the benefits that future generations obtain from ecosystems.
  • The degradation of ecosystem services could grow significantly worse during the first half of this century and is a barrier to achieving theMillennium Development Goals.
  • The challenge of reversing the degradation of ecosystem while meeting increasing demands for services can be partially met under some scenarios considered by the MA, but will involve significant changes in policies, institutions and practices that are not currently under way. Many options exist to conserve or enhance specific ecosystem services in ways that reduce negative trade-offs or that provide positivesynergies with other ecosystem services.

The bottom line of the MA findings has been that human actions aredepleting Earth’snatural capital, putting such strain on the environment that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted. At the same time, the assessment shows that with appropriate actions it is possible to reverse the degradation of many ecosystem services over the next 50 years, but the changes in policy and practice required are substantial and not currently underway.[citation needed]

Legacy

[edit]

In 2008, a report calculated that the world's richest countries caused environmental damage to developing nations at more than the entire developing world debt of $1.8 trillion.[3]
