IUCN Protected Area Categories
IUCN protected area categories, or IUCN protected area management categories, are categories used to classify protected areas in a system developed by the International Union for Conservation of Nature (IUCN). The enlisting of such areas is part of a strategy being used toward the conservation of the world's natural environment and biodiversity. The IUCN has developed the protected area management categories system to define, record and classify the wide variety of specific aims and concerns when categorising protected areas and their objectives. This categorisation method is recognised on a global scale by national governments and international bodies such as the United Nations and the Convention on Biological Diversity. Categories Category Ia – strict nature reserve A strict nature reserve (IUCN Category Ia) is an area which is protected from all but light human use in order to protect its biodiversity and also possibly its geological/geomorphical features. These areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Logo
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Management Area
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Database On Protected Areas
The World Database on Protected Areas (WDPA) is the largest assembly of data on the world's terrestrial and marine protected areas, containing more than 260,000 protected areas as of August 2020, with records covering 245 countries and territories throughout the world. The WDPA is a joint venture between the United Nations Environment Programme World Conservation Monitoring CentreUNEP-WCMC and the International Union for Conservation of NatureIUCN World Commission on Protected AreasWCPA. Data for the WDPA is collected from international convention secretariats, governments and collaborating NGOs, but the role of custodian is allocated to the Protected Areas Programme of UNEP-WCMC, based in Cambridge, UK, who have hosted the database since its creation in 1981. The WDPA delivers invaluable information to decision-makers around the world, particularly in terms of measuring the extent and effectiveness of protected areas as an indicator for meeting global biodiversity targets. In Oct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Commission On Protected Areas
The World Commission on Protected Areas (WCPA) is one of six commissions of the International Union for Conservation of Nature (IUCN). History In 1948, the IUCN established a Committee on National Parks. Two decades later the IUCN had been asked by the international community to take responsibility for preparing a world list of national parks in keeping with its role as a network to share the world’s knowledge on nature conservation, and in 1960, the IUCN raised the status of the Committee to that of a permanent Commission, with the creation of the Commission on National Parks. In 1996, the World Commission on Protected Areas took on its current name with the approval of the IUCN congress. Organizational structure WCPA is a network of volunteers. Secretariat support is provided by staff of the IUCN Programme on Protected Areas, with whom WCPA implements a shared strategic plan and work plan. The Commission has a Steering Committee, and the Chair is elected every four years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNEP-WCMC
The UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) is a collaboration centre of UN Environment Programme, based in Cambridge in the United Kingdom. UNEP-WCMC has been part of UN Environment Programme since 2000, and has responsibility for biodiversity assessment and support to policy development and implementation. The World Conservation Monitoring Centre was previously an independent organisation jointly managed by IUCN, UN Environment Programme and WWF established in 1988. Prior to that, the centre was a part of the IUCN Secretariat. Areas of work The activities of UNEP-WCMC include biodiversity assessment, support to international conventions such as the Convention on Biological Diversity (CBD) and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), capacity building and management of both aspatial and spatial data on species and habitats of conservation concern. UNEP-WCMC has a mandate to facilitate the delive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landsat Gbreef
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or 100 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agrobiodiversity
Agricultural biodiversity or agrobiodiversity is a subset of general biodiversity pertaining to agriculture. It can be defined as "the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and that provide food and non-food agricultural products.” It is managed by farmers, pastoralists, fishers and forest dwellers, agrobiodiversity provides stability, adaptability and resilience and constitutes a key element of the livelihood strategies of rural communities throughout the world. Agrobiodiversity is central to sustainable food systems and sustainable diets. The use of agricultural biodiversity can contribute to food security, nutrition security, and livelihood security, and it is critical for climate adaptation and climate mitigation. Etymology It is not clear when exactly the term agrobiodiversity was coined nor by whom. The 1990 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecotourism
Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Ecotourism may focus on educating travelers on local environments and natural surroundings with an eye to ecological conservation. Some include in the definition of ecotourism the effort to produce economic opportunities that make conservation of natural resources financially possible. Generally, ecotourism deals with interaction with biotic components of the natura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Restoration Ecology
Restoration ecology is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human interruption and action. Effective restoration requires an explicit goal or policy, preferably an unambiguous one that is articulated, accepted, and codified. Restoration goals reflect societal choices from among competing policy priorities, but extracting such goals is typically contentious and politically challenging. Natural ecosystems provide ecosystem services in the form of resources such as food, fuel, and timber; the purification of air and water; the detoxification and decomposition of wastes; the regulation of climate; the regeneration of soil fertility; and the pollination of crops. These ecosystem processes have been estimated to be worth trillions of dollars annually. There is consensus in the scientific community that the current envi ...

Seascape
A seascape is a photograph, painting, or other work of art which depicts the sea, in other words an example of marine art. The word originated as a formation from landscape, which was first used of images of land in art. By a similar development, "seascape" has also come to mean actual views of the sea itself, and to be applied in planning contexts to geographical locations possessing a good view of the sea. History The word seascape was first recorded and coined in 1790. It was modelled after the term landscape. In modern times, seascapes have endured partially in depictions of maritime works of art, as well as views of the sea. Planning use In the UK a seascape is defined in planning and land use contexts as a combination of adjacent land, coastline and sea within an area, defined by a mix of land-sea inter-visibility and coastal landscape character assessment, with major headlands forming division points between one seascape area and the next. This approach to coas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landscape
A landscape is the visible features of an area of land, its landforms, and how they integrate with natural or man-made features, often considered in terms of their aesthetic appeal.''New Oxford American Dictionary''. A landscape includes the physical elements of geophysically defined landforms such as (ice-capped) mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings, and structures, and transitory elements such as lighting and weather conditions. Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect a living synthesis of people and place that is vital to local and national identity. The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions. It is the dyn ...
