The climate and biodiversity crises are interconnected and their solutions are mutually dependent.

 


A new study has strengthened calls for coordinated action on climate change and nature loss, by calculating the CO2 emissions countries could save if they conserve and restore ecosystems on land, in line with proposed international targets for nature conservation. It comes ahead of Biodiversity Day at the COP27 climate conference, on November 16, during which ministers, business and community leaders from around the world will discuss the current state of nature, showcase current action on ecosystem restoration and nature-based solutions and strive to inspire and enact greater commitments to jointly tackle climate change and nature loss.The new report, Strengthening Synergies: Climate Change Mitigation Benefits from Achieving Global Biodiversity Targets, presents new scientific analysis using improved data on biodiversity and carbon stocks and sequestration, combined with modelling of land use change.

Aligning with new goals and targets expected to be adopted at the end of 2022 as part of the UN’s post-2020 global biodiversity framework, the study reveals that carefully targeted efforts to conserve 30 per cent of the Earth’s ecosystems on land by 2030, alongside restoring 15 per cent of converted landscapes, could reduce carbon dioxide emissions (GtCO2) by at least three gigatons a year.

Global discussions and commitments on the environment are increasingly reflecting the vital links between climate change and nature, underscoring the need for integrated action. The Glasgow Climate Pact at last year’s COP26 UN climate conference recognised these interdependencies and the importance of nature-based solutions (NbS), meanwhile, new global targets for nature emphasise the importance of carbon savings through NbS.

THE BLUE WHALE FALLS TO EXTINCTION.

Image
The blue whale is listed as endangered throughout its range under the ESA and is thus considered depleted throughout its range under the MMPA. Internationally, blue whales received complete legal protection from commercial whaling in 1966 under the International Convention for the Regulation of Whaling. To address this, the Red List Index (RLI) has been developed, which shows trends in the status of groups of species based only on genuine improvements or deteriorations in status of sufficient magnitude to qualify species for listing in more threatened or less threatened Red List Categories. Species Categorized as Extinct (EX)

Worldwide celebrations of the International Day for Biological Diversity 2023.

  EVENT : From Agreement to Action: the Central Role of Water to Build Back Biodiversity - IDB 2023 In celebration of the International Day for Biological Diversity 2023 , on May 22nd ; this event will illustrate the critical interlinkages between freshwater and biodiversity and showcase the outcomes of the UN Biodiversity Conference (COP 15) and UN 2023 Water Conference . The Water Action Agenda commitments on biodiversity made by different stakeholders at the United Nations 2023 Water Conference will be discussed at the event. All aspects of human wellbeing depend on water. In turn the planet’s water cycle is dependent on and mediated by biodiversity and water-related ecosystems. Freshwater ecosystems cover less than 1% of the Earth's surface but harbour more than 10% of all species. The importance of biodiversity and waterrelated ecosystems is reflected in the Sustainable Development Goal 6 and in particular Target 6.6. However, biodiversity in freshwater ecosystems is in dang...
