EcoHealth Alliance 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.

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

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

Species Discovery Explore how scientists discover, classify and name species previously unknown to science. ARKive School Museum Guess Zoo

- 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. As a small conservation charity, Wildscreen eventually reached the point where it could no longer financially sustain the ongoing costs of keeping Arkive free and online or invest in its much needed development. Therefore, a very hard decision was made to take the www.arkive.org website offline in February 2019.

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. Specifically, they committed to: Estimate the greenhouse gas emissions of UN system organizations consistent with accepted international standards; Undertake efforts to reduce greenhouse gas emissions; Analyze the cost implications and explore budgetary modalities of purchasing carbon offsets to eventually reach climate neutrality. The UN Climate Neutral Strategy highlights the advantages of harmonization. The main building at UN Headquarters in New York was recently renovated.

Endangered Species Journey to Planet Earth . Ecosystems We are intimately familiar with ecosystems. They are the woodlands where we live, hunt, cut timber, or hike; the lakes, streams, and rivers we fish, boat, transport our goods on, and tap for water; the rangelands where we graze our cattle; the beaches where we play, and the marine waters we trawl; the farmlands we till; even the urban parks and green spaces we stroll. In effect, every centimeter of the planet is part of an ecosystem. Ecosystems are: They are systems combined of organic and inorganic matter and natural forces that interact and change. When talking about ecosystems, the matter of scale or size is important. A small bog, a single sand dune, or a tiny patch of forest may be viewed as an ecosystem, unique in its mix of species and microclimate — a microenvironment. In World Resources 2000-2001, "ecosystem" refers to an even larger concept — categories of ecosystems. However, the divisions between ecosystems are less important than the linkages between them.

Infopacket: Biomes Scientists divide the world into large natural areas called biomes. Each biome is known for certain kinds of plants and animals. But what’s really at the heart of a biome is its climate. In this downloadable Spotlight, get 8 packed pages of information about the world’s major biomes. ARIES :: The ARIES approach Overview With growing interest in using ecosystem services for decision making, demand has grown for systematic methods and tools to quantify ecosystem service values. ARIES maps the potential provision of ecosystem services (sources), their users (use), and biophysical features that can deplete service flows (sinks) using ecological process models or Bayesian models. ARIES then uses a series of agent-based flow algorithms to map actual service flow from ecosystems to people. Integrated modeling platform Through artificial intelligence and semantic modeling, ARIES assembles the appropriate models - deterministic or probabilistic and spatial data to quantify and map ecosystem services at the appropriate spatial scale and ecological and socioeconomic context. A benefits- and beneficiaries-based approach to ecosystem services Spatial dynamics of ecosystem services Data and model integration A pluralistic approach to economic valuation
