Declining marine biodiversity

Other examples Climate change impacts on biodiversity in the Arctic The Arctic, Antarctic and high latitudes have had the highest rates of warming, and this trend is projected to continue, as the above-mentioned Global Biodiversity Outlook 3 notes p. In the Arctic, it is not just a reduction in the extent of sea ice, but its thickness and age. Less ice means less reflective surface meaning more rapid melting.

Human well-being at risk: Landmark reports highlight options to protect and restore nature and its vital contributions to people Infographic: Katharina Funk Icons designed by Freepik from www. The extensively peer-reviewed reports are providing answers for the questions: Why is biodiversity important?

Where are we making progress? What are the main threats and opportunities for biodiversity? And how can we adjust our policies for a more sustainable future? The assessments are carrying an important and urgent message: Biodiversity is still rapidly declining in all regions of the world.

And it is unlikely to stop. Threads for biodiversity loss are manifold: Habitat loss, overexploitation and unsustainable use of natural resources; air, land and water pollution and in increasing numbers and impacts of invasive alien species and climate change are just a few examples.

We know — in theory — how to protect our nature and there are a number of positive examples out there. Jake Rice Canadaco-chair of the Americas assessment In a business as usual scenario, climate change will be the fastest driver of biodiversity decline in the Americas by There are local communities, whose practices, such as polyculture or agroforestry, have the potential to increase biodiversity again.

This will cause a loss of indigenous knowledge and traditional practices that are originally enhancing biodiversity. This area is as big as Germany, Austria, Belgium and the Netherlands together. Especially the marine and coastal ecosystems — having a significant economic importance — are under threat.

A continuous degradation can therefore have serious implications for tourism as well as for fisheries, food security and the overall marine biodiversity. Madhav Karki Nepalco-chair of the Asia-Pacific assessment An overall decline of biodiversity was reported, but there was also a success in increasing protected areas.

There are, however, doubts whether these efforts are sufficient to stop the overall decrease of biodiversity. Apart from that, the biggest threat to biodiversity is the increasing variety and abundance of invasive alien species.

The most threatened ecosystems are forests, alpine ecosystems, inland freshwater and wetlands, as well as coastal systems.

Markus Fischer Switzerlandco-chair of the Europe and Central Asia assessment Europe and Central Asia are facing a rapid decline of biodiversity mainly due to increasing conventional agricultural and forestry practices.

But there are also some examples of sustainable agricultural and forestry practices. Nevertheless, Europe and Central Asia are facing a loss of associated indigenous and local knowledge and practices.

The report stresses that economic growth needs to be decoupled from the degradation of biodiversity to facilitate sustainable development. My main interests are climate policy, sustainability, environmental ethics and social-ecological systems.Major threats Biodiversity is under serious threat as a result of human activities.

The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation. The report provides the most detailed global analysis of biodiversity to date, with over million records, providing an accurate view of the current state of the Earths decline in biodiversity.

By restoring marine biodiversity through sustainable fisheries management, pollution control, maintenance of essential habitats, and the creation of marine reserves, we can invest in the productivity and reliability of the goods and services that the ocean provides to humanity. Marine biodiversity – a vital resource > For a long time the significance of biological diversity in the world’s oceans was unclear.

It is now known to play a vital role in maintaining the functionality and productivity of ecosystems. It also makes habitats more resilient to environmental change.
