inventory of the nature: On Monday starts in Paris, a conference about the new Report on the global diversity of species. Three years 150 experts from 50 countries have carried on the existing Knowledge and analyzed.

Now you are filing with a group of about 100 government officials for a week-long a paper with the key messages of your report, which should then serve as a basis for Action for politicians. On 6. May want to publish the world’s biodiversity sitätsrat IPBES this summary. Participating researchers are hoping the new to give rise to a change in the direction of sustainable development in a toast.

climate change, intensive agriculture, pollution, Overfishing, poaching, and the destruction of natural habitats, the causes are known. How bad is the biodiversity of the world, was last shown in 2005, the Millennium Ecosystem Assessment: Ecosystems had been subjected to in the previous 50 years, larger loads than ever before. And a reversal is urgently needed. Now the IPBES report. Still nothing about his results. That in the meantime something has fundamentally improved, is hardly to be expected. The current literature show that the decline in biodiversity should be stopped, says Josef Settele from the Helmholtz centre for environmental research (UFZ) in Halle, one of the three main authors of the IPBES report.

in addition to the problems possible solutions in most cases are known. What can change in a new report on the still sobering development? “The IPBES global Assessment brings together, for the first time since the Millennium Ecosystem Assessment of 2005, the entire scientific knowledge of the status and Trend of species, Ecosystems and ecosystem services,” says Günter Mitlacher, Director International biodiversity policy WWF. “Since then, new findings have been added, so that with the IPBES Assessment the Knowledge is up to date.”

And, IPBES-chair Sir Robert Watson, the prerequisite for successful species protection: “Policy measures, efforts, and actions will be – on all levels – can only be successful if they are based on the best Knowledge and Evidence. This is what the global Assessment of the IPBES.” Almost 15 000 sources have been analyzed by the experts for its report, more than 250 further specialists to the provided Knowledge directly. For the first time, insights, and interests have been included knowledge of indigenous peoples and other Local.

The researchers have tested, among other things, how far the world has come in already agreed species protection objectives. The 2010 of the conference to the Convention on biological diversity (CBD) adopted the Aichi targets. You see, for example, that by 2020 the rate of loss of all natural habitats is at least halved, the Overfishing of the oceans stopped, and 17 percent of the land area and 10 percent of oceans are under protection. Also, the implementation of the UN objectives for sustainable development (SDG) and of the Paris climate agreement was attended by the experts in the view.

The special significance of the seas co-author Julian Gutt, a marine biologist stresses at the Alfred-Wegener-Institute in Bremerhaven. “The life in the sea is almost as important for humans as life on Land.” What happens in it, but it is not so visible. Gutt, with views of the oceans, nevertheless, cautiously optimistic. “In the sea of knowledge, after all, what we, so far, fewer species become extinct as a country.” The give hope that decimated the species could recover.

could look Like our world in the future, IPBES-authors in the six scenarios, for example, under the assumption that mankind makes more as in the past, or learns to operate in a more globally or regionally in a sustainable manner. This is one of the areas in which the social science is in demand. A unique interface between policy and science Jens now kowitz of the Helmut-Schmidt-University Hamburg announced the IPBES report. It is not only the immediate causes, but also indirect drivers of biodiversity loss, such as Power and financing structures.

Often the world’s biodiversity sitätsrat is compared with the IPCC, the Knowledge on the status and the possible consequences of climate change. The IPBES report and should be, among other things, a basis for the next conference of the parties of the biodiversity Convention (CBD) in 2020 in the Chinese Kunming.
