First, we use a recent estimate of a background rate of 2 mammal extinctions per 10,000 species per 100 years (that is, 2 E/MSY), which is twice as high as widely used previous estimates. Below, we review the causes, consequences and possible solutions. As an illustration, an analysis using the OECD ‘baseline scenario’ shows a considerable decline of the biodiversity intactness in still existing water bodies in 2000, especially in temperate and subtropical regions, and a further decline especially in tropical regions in 2050. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed in order to highlight urgent conservation cases and inform environmental policy with appropriate biodiversity information in a timely manner.

The poor rely more heavily on subsistence products such as wood fuels and wild foods, and on products harvested from natural areas other than forests. The planet's biodiversity is under threat and the main culprit is the one who, paradoxically, depend on it most: human being. The proportion of threatened reptile species is highest in freshwater environments, tropical regions and on oceanic islands, while data deficiency was highest in tropical areas, such as Central Africa and Southeast Asia, and among fossorial reptiles. Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing. The Conservation Status of the World's Reptiles. The loss of biodiversity is a significant issue for scientists and policy-makers and the topic is finding its way into living rooms and classrooms.

Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 114 times higher than the background rate. As a result, in 2010 world leaders adopted 20 targets — known as the Aichi Biodiversity Targets — for the period 2011–2020 with the aim to 'significantly reduce the current rate of biodiversity loss'. Our results demonstrate a lack of spatial congruence between the economic value of ecosystem services and biodiversity in tropical forests. 31 Figure 2.4 Main direct drivers of change in biodiversity and ecosystems 32 Figure 2.5 General biofuel pathway with inputs and environmental impacts 36 Figure 2.6 Example of displacement mechanism causing indirect deforestation 37 • Fisheriesh avenosignif icantadverse impactsonth reatenedspecies, • The i mpacts  of fis heries on  stock s, speci es and e cosys tems ar e, been brought to levels that are not detrimental to ecosys, • Pollutants (of al l types) have b een brought to levels t hat are not, • Pollutionfrom excessnut rientshas beenbrought tolevels thatare. %%EOF The formalization and mainstreaming of a network of CCAs in the State in conjunction with the Nagaland Government and Forest Department.

However, if a loss in biodiversity leads to a decrease in biomass of feed, farmers will no longer be able to raise enough cattle due to the feed shortage. Convergence in these estimates could be accelerated by adaptive learning methods where the estimation of uncertainty is prioritised and used to guide future research. These initiatives have sought to enhance agricultural profitability among small and marginal farmers while reducing the environmental footprint of agriculture. In the short term, inclusion of unprotected priority areas in the national system is the best way to improve biological conservation. Species are becoming extinct at the fastest rate known in geological history and most of these extinctions have been tied to human activity. The International Union for the Conservation of Nature (IUCN) predicts that current extinction rates are already 100-1000 These methods revealed that the, Der Verlust an Biodiversität gilt als eines der zentralen Umweltprobleme.
