Endangered speciesAn endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas.
Jaccard indexThe Jaccard index, also known as the Jaccard similarity coefficient, is a statistic used for gauging the similarity and diversity of sample sets. It was developed by Grove Karl Gilbert in 1884 as his ratio of verification (v) and now is frequently referred to as the Critical Success Index in meteorology. It was later developed independently by Paul Jaccard, originally giving the French name coefficient de communauté, and independently formulated again by T. Tanimoto. Thus, the Tanimoto index or Tanimoto coefficient are also used in some fields.
Holistic management (agriculture)Holistic Management (from ὅλος holos, a Greek word meaning all, whole, entire, total) in agriculture is an approach to managing resources that was originally developed by Allan Savory for grazing management. Holistic Management has been likened to "a permaculture approach to rangeland management". Holistic Management is a registered trademark of Holistic Management International (no longer associated with Allan Savory). Holistic management describes a systems thinking approach to managing resources.
Tibetan PlateauThe Tibetan Plateau (, also known as the Qinghai–Tibet Plateau or the Qing–Zang Plateau () or as the Himalayan Plateau in India, is a vast elevated plateau located at the intersection of Central, South and East Asia covering most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces in Western China, southern Xinjiang, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti (Himachal Pradesh) as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern
Rewilding (conservation biology)Rewilding is a form of ecological restoration aimed at increasing biodiversity and restoring natural processes. It differs from ecological restoration in that, while human intervention may be involved, rewilding aspires to reduce human influence on ecosystems. It is also distinct in that, while it places emphasis on recovering geographically specific sets of ecological interactions and functions that would have maintained ecosystems prior to human influence, rewilding is open to novel or emerging ecosystems which encompass new species and new interactions.
Deforestation and climate changeDeforestation is a primary contributor to climate change, and climate change affects forests. Land use changes, especially in the form of deforestation, are the second largest anthropogenic source of atmospheric carbon dioxide emissions, after fossil fuel combustion. Greenhouse gases are emitted during combustion of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions.
Ordos DesertThe Ordos Desert () is a desert/steppe region in Northwest China, administrated under the prefecture of Ordos City in the Inner Mongolian Autonomous Region (centered ca. ). It extends over an area of approximately , and comprises two sub-deserts: China's 7th-largest desert, the Kubuqi Desert, in the north; and China's 8th-largest desert, the Mu Us Desert, in the south. Wedged between the arable Hetao region to the north and the Loess Plateau to the south, the soil of the Ordos Desert is mostly a mixture of dry clay and sand, and as a result is poorly suited for agriculture.
