Geography is the study of natural and human constructed phenomena from a spatial perspective. Geography has two main sub disciplines:
Human geography includes such subjects as demography, human settlements, transportation, recreation and tourism, resources, religion, social traditions, human migration, agriculture, urban systems, and economic activities
Physical geography is concerned with the study of the Earth’s atmosphere, biosphere, hydrosphere, and lithosphere from theoretical and applied viewpoints.
Sometimes the disciplines of human and physical geography combine knowledge to create a more holistic synthesis.

Highveld grasslandsLast Updated on 2015-07-04 13:52:52
WWF Terrestrial Ecoregions Collection
Highveld grasslands ecoregion covers a large portion of west-central South Africa. Grasslands all over the world have experienced dramatic habitat destruction as a result of anthropogenic changes. The Highveld grasslands are no exception, with agriculture severely fragmenting this once-expansive region. This ecoregion now provides the last remaining stronghold of a number of grassland species that have suffered major reductions in abundance in the grassland biome, and which are consequently threatened with extinction (e.g. the Blue Crane (Anthropoides paradisea). There is a relatively biodiverse vertebrate fauna, with 608 taxa recorded. This ecoregion is part of the Montane Grasslands and Shrublands biome, within the Afrotropics Realm.
The ecoregion draws its name from the high interior plateau known as... More »
East African montane moorlandsLast Updated on 2015-07-02 10:29:19
The East African montane moorlands is a relatively small alpine ecoregion in eastern Africa. The habitat is virtually treeless since it occupies a zone above the treeline. This ecoregion, classified as an element of the montane grasslands and scrublands biome, has a land area measuring only about 1300 square miles. The ecoregion, lying at the upper zones of ancient volcanoes, exhibits low species richness of higher level faunal organisms, but manifests moderate plant and animal endemism, including support of certain extremophiles. There is particularly high endemism among amphibians and small mammals of the ecoregion. Many of the plant species that occur in the ecoregion have adapted interesting morphological features to allow survival in the extreme cold here.
The upper elevations of the ecoregion have persistent glacial cover. Although some of the ecoregion (e.g. Mount Kilamanjaro)... More »
Madagascar succulent woodlandsLast Updated on 2015-07-01 18:43:46
WWF Terrestrial Ecoregions Collection
The Madagascar succulent woodlands ecoregion comprises a mosaic of succulent xeric adapted plants and deciduous forests that represent critical habitats for many species of animals and plants restricted to the western region of Madagascar. Some of the remarkable fauna and flora found in this ecoregion include the Giant jumping rat (Hypogeomys antimena), the Flat-tailed tortoise (Pyxis planicauda), two species of baobabs and several species of primates. The Madagascar succulent woodlands is classified within the Desert and Xeric Shrublands Biome, and is part of the Afrotropics Realm.
These succulent woodlands are situated in southwestern Madagascar extending northward to the central western part of the island. Its southern limit is the start of the Madagascar spiny thicket and northern limit the lower... More »
ComorosLast Updated on 2015-06-03 13:33:51Comoros is a nation of 730,000 people composed of three islands (Ngazidja or "Grande Comore", Mwali or "Mohéli" and Nzwani or "Anjouan") in the Indian Ocean, at the northern mouth of the Mozambique Channel, about two-thirds of the way between northern Madagascar and northern Mozambique.
Comoros also claims a fourth island Mayotte or "Mahoré" which is under French administration. One of the world's poorest countries, the islands comprising Comoros have inadequate transportation links, a young and rapidly increasing population, and few natural resources. The country is not self-sufficient in food production. Rice, the main staple, accounts for the bulk of imports.
The low educational level of the labor force contributes to a subsistence level of economic activity, high unemployment, and a... More »
Spratly IslandsLast Updated on 2015-06-01 15:45:31The Spratly Islands consist of more than 150 small islands or reefs scattered over a sea area of nearly 360,000 square kilometres in the South China Sea, about two-thirds of the way from southern Vietnam to the southern Philippines. The closest countries to the Spratly Islands are Malaysia, Vietnam, Brunei and the Philippines.
Abundant in marine biodiversity, the Spratly Islands lie in rich fishing grounds and potential gas and oil deposits. (See Energy profile of South China Sea)
These islands are strategically located near several primary strategic shipping lanes in the central South China Sea.
There are no indigenous inhabitants. But there are scattered garrisons occupied by military personnel of several claimant states, notably the Philippines.
They are claimed in their entirety by Taiwan, Vietnam and China, while portions are claimed by Malaysia and... More »
