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

Teaching resources for 11-14 year olds Persuasive Writing — Invasive Species Students will learn about the applications and techniques of persuasive writing before writing their own persuasive article for a school newsletter on the topic of invasive species. Climate Change Students will learn about the causes and consequences of climate change, and the ways in which climate change can impact plants and animals. News and Features — eBird Sam Murray, June eBirder of the Month Please join us in congratulating Sam Murray of Augusta, GA, winner of the June 2017 eBird Challenge, sponsored by Carl Zeiss Sports Optics. Our June winner was drawn from eBirders who submitted 15 or more eligible checklists containing at least one breeding code in June. Sam’s name was drawn randomly from the 1,769 eligible eBirders who achieved the June challenge threshold.

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:

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.

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.

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. 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. Ecology Ecology is a large theme, and often not given full coverage in a biology class due to time constraints. Below are some basic lessons on ecology and environmental science.

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.
