Hem - Historiska Ecosystem Locations reported by various studies as undergoing high rates of land cover change in the past few decades In the case of forest cover change, the studies refer to the period 1980–2000 and are based on national statistics, remote sensing, and to a limited degree expert opinion. In the case of land cover change resulting from degradation in drylands (desertification), the period is unspecified but inferred to be within the last half-century, and the major study was entirely based on expert opinion, with associated low certainty. 30 Nov 2007 - by Philippe Rekacewicz, Emmanuelle Bournay, UNEP/GRID-Arendal Ecosystem carbon payback time The ‘carbon debt’ of biofuels is the number of years it can take to offset the carbon emissions generated by converting land for biofuels. 01 Mar 2012 - by Riccardo Pravettoni, UNEP/GRID-Arendal Natural ecosystem conversion 03 Oct 2009 - by Riccardo Pravettoni, UNEP/GRID-Arendal Human impact, Greater Asian Mountains region 2000 and scenarios for 2030

- ARKive - Extensive Animal Encyclopedia Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Despite appeals for support, just 85 of our 5.6 million users in 2018 made a donation.

and Sustainability “I would like to see our renovated Headquarters complex eventually become a globally acclaimed model of efficient use of energy and resources. Beyond New York, the initiative should include the other United Nations headquarters and offices around the globe.” Secretary-General Ban Ki-moon Speech on World Environment Day 2007 In 2007, on World Environment Day (5 June), Secretary-General Ban Ki-moon, with the above words, made public his ambition to make the United Nations more efficient in its operations. In October 2007, at the meeting of the UN System Chief Executives Board for Coordination (CEB), the Executive Heads of UN agencies, funds and programmes committed to move their respective organizations towards climate neutrality, and developed the UN Climate Neutral Strategy. Specifically, they committed to: The UN Climate Neutral Strategy highlights the advantages of harmonization. The main building at UN Headquarters in New York was recently renovated. Greening the Blue
Endangered Species IUFRO Alien invasive species and international trade What does this IUFRO Unit do? The IUFRO Unit 7.03.12 has been established to examine global forestry issues related to the unwanted international movement of alien invasive species, including fungi, insects, nematodes, and plants. The increasing emphasis on pathways for movement of alien invasive species, especially those associated with packaging wood and plants for planting will provide a broad focus for the work of the unit. This emphasis provides an opportunity to integrate across a range of invasive organisms so that links to other IUFRO Working Parties dealing with insects, pathogens and invasive plants will be a priority. There are close relations with other IUFRO working parties as well as the International Forestry Quarantine Research Group (IFQRG) affiliated with the Food and Agriculture Organization, International Plant Protection Convention. Specific objectives of the Unit Activities of the Unit These will include regular meetings at 1-2 year intervals. For further information
Invasive Alien Species Indicator What are we about? Invasive alien species (IAS) are a major threat to global biodiversity. As a result ‘Trends in IAS’ was selected as one of 22 Headline Indicators (HI) to measure progress towards the Convention on Biological Diversity's target of reducing the rate of loss of biodiversity by 2010.

Populating the pressure indicator for invasive alien species – in other words ‘number of invasive alien species per country’ (see McGeoch et al. 2010) – is dependent on the availability of high quality lists of invasive alien species for a range of taxonomic group, countries and regions.
