The SPM presents the key messages and policy options, as approved by the IPBES Plenary. Loss of biodiversity definition: refers to either the ongoing extinction of species at a global level or the local reduction or loss of species in a given habitat.
The species richness and variation of species are often used to measure the loss rate in the local level. “The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture,” said IPBES Chair, Sir Robert Watson. Loss of biodiversity is therefore shown to be not only an environmental issue, but also a developmental, economic, security, social and moral issue as well. Together, assessments undertaken by IPBES, FAO, CBD and other organizations point to the urgent need for action to better conserve and sustainably use biodiversity and to the importance of cross-sectoral and multidisciplinary collaboration among decision-makers and other stakeholders at all levels.”IPBES has now released the Summary for Policymakers (SPM) of the Global Assessment report. Healthy biodiversity is the essential infrastructure that supports all forms of life on earth, including human life. Facts about Loss of Biodiversity 5: how to measure the loss rate. To access the SPM, photos, ‘B-roll’ and other media resources go to: Often described as the “IPCC for biodiversity”, IPBES is an independent intergovernmental body comprising more than 130 member Governments.
The picture is less clear for insect species, but available evidence supports a tentative estimate of 10% being threatened. Fragmented ecosystems are generally not as Our editors will review what you’ve submitted and determine whether to revise the article.The idea of biodiversity is most often associated with Even though a species is not eliminated from the ecosystem or from the biosphere, its Biodiversity loss is typically associated with more permanent ecological changes in In contrast, biodiversity losses from disturbances caused by humans tend to be more severe and longer-lasting. John P. Rafferty writes about Earth processes and the environment.
decided to “… achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the global, regional and national levels…” (decision VI/26). At least 680 vertebrate species had been driven to extinction since the 16th century and more than 9% of all domesticated breeds of mammals used for food and agriculture had become extinct by 2016, with at least 1,000 more breeds still threatened.“Ecosystems, species, wild populations, local varieties and breeds of domesticated plants and animals are shrinking, deteriorating or vanishing. “This loss is a direct result of human activity and constitutes a direct threat to human well-being in all regions of the world.”To increase the policy-relevance of the Report, the assessment’s authors have ranked, for the first time at this scale and based on a thorough analysis of the available evidence, the five direct drivers of change in nature with the largest relative global impacts so far.
Established by Governments in 2012, it provides policymakers with objective scientific assessments about the state of knowledge regarding the planet’s biodiversity, ecosystems and the contributions they make to people, as well as the tools and methods to protect and sustainably use these vital natural assets.
This is why the scientific evidence compiled in this IPBES Global Assessment is so important. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide.”“The Report also tells us that it is not too late to make a difference, but only if we start now at every level from local to global,” he said. I want to extend my thanks and congratulations to the IPBES community for their hard work, immense contributions and continued partnership.”“The Global Assessment of biodiversity and ecosystem services adds a major element to the body of evidence for the importance of biodiversity to efforts to achieve the Zero Hunger objective and meet the Sustainable Development Goals.

The essential, interconnected web of life on Earth is getting smaller and increasingly frayed,” said Prof. Settele. Our efforts to conserve biodiversity and ecosystems must be underpinned by the best science that humanity can produce. But our safety net is stretched almost to breaking point,” said Prof. Sandra Díaz (Argentina), who co-chaired the Assessment with Prof. Josef Settele (Germany) and Prof. Eduardo S. Brondízio (Brazil and USA).

The primary drivers of biodiversity loss are influenced by the exponential growth of the human population, increased consumption as people strive for more affluent lifestyles, and reduced resource efficiency.Relative biomass on Earth.
Our local, indigenous and scientific knowledge are proving that we have solutions and so no more excuses: we must live on earth differently.
