List of terrestrial ecoregions (WWF)

The WWF identifies terrestrial, freshwater, and marine ecoregions. The terrestrial scheme divides the Earth's land surface into 8 terrestrial ecozones, containing 867 smaller ecoregions. Each ecoregion is classified into one of 14 major habitat types, or biomes. Additional ecoregions for Antarctic Realm are currently being incorporated (based on Terauds et al. 2012). Antarctic Realm - Tundra Biome: 1 North-east Antarctic Peninsula; 2 South Orkney Islands; 3 North-west Antarctic Peninsula; 4 Central south Antarctic Peninsula; 5 Enderby Land; 6 Dronning Maud Land; 7 East Antarctica; 8 North Victoria Land; 9 South Victoria Land; 10 Transantarctic Mountains; 11 Ellsworth Mountains; 12 Marie Byrd Land; 13 Adelie Land; 14 Ellsworth Land; 15 South Antarctic Peninsula.

Physiographic Regions

Geomorphic, or physiographic, regions are broad-scale subdivisions based on terrain texture, rock type, and geologic structure and history. Nevin Fenneman's (1946) three-tiered classification of the United States - by division, province, and section - has provided an enduring spatial organization for the great variety of physical features. The composite image presented here clearly shows the topographic textures and generalized geology (by age) from which the physical regions were synthesized. The features we describe represent many of these subdivisions. Subregion. A subregion is a part of a larger region or continent and is usually based on location.


Cardinal directions, such as south or southern, are commonly used to define a subregion. United Nations subregions[edit] The Statistics Division of the United Nations (UN) is in charge of the collection, processing, and dissemination of statistical information for the UN.[1] In 1999, it developed a system of macro-geographical (continental) regions, subregions, and other selected economic groups to report advances towards achieving numerous millennial development goals worldwide. This geoscheme was devised for statistical purposes and is used for carrying out statistical analysis.[2] The division's first publication was the book World's Women 2000: Trends and Statistics in 2000.

According to the UN, the assignment of countries or areas to specific groupings is for statistical convenience and does not imply any assumption regarding political or other affiliation of countries or territories.[3] Asia[edit] World Maps.

David Skilling is founding director at Landfall Strategy Group, a Singapore-based advisory firm. By Parag Khanna and David Skilling – Special to CNN In the current phase of globalization, financial, ecological, political and social crises are occurring simultaneously and magnifying each other in unpredictable ways. From the Fukushima nuclear meltdown reshaping German politics and the European power industry, to America’s sub-prime mortgage meltdown threatening the Eurozone, such chain reactions are undermining an already fragile stability.

Physiographic regions of the world. The Physiographic Regions of the world are a means of defining the Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin Fenneman in 1916, that further defines landforms into: 1. physiographic divisions; 2. physiographic provinces; and 3. physiographic sections.[1] This foundational model, which Fenneman used to classify the United States, was the basis for similar classifications of other continents later, and is still considered basically valid.[2] Introduction[edit] During the early 1900s, the study of regional-scale geomorphology was termed "physiography".

Physiographic regions of the world

Unfortunately, physiography later was considered to be a contraction of "physical" and "geography", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline. For the purposes of physiographic mapping, landforms are classified according to both their geologic structures and histories. Maps. Tokyo earthquake, tsunami puts data centers, cloud services at risk. Japan was reeling after an 8.9 magnitude earthquake and tsunami hit the Northeast coast and also impacted Tokyo.

Tokyo earthquake, tsunami puts data centers, cloud services at risk

As a result, much of the Pacific Ocean is under a tsunami warning. The disaster comes as many tech giants were setting up data centers in Tokyo to meet demand for cloud computing services. It's unclear how data centers are holding up. TV reports indicate that mobile services are up in Tokyo, but spotty. According to the U.S. Geospatial Revolution Project. Geography.
