Semi-arid Pampas
The Semi-arid Pampas, also known as the Dry Pampas, is a temperate grassland ecoregion of central Argentina. Setting The Semi-arid Pampas cover an area of , including western Buenos Aires Province, southern Cordoba and San Luis Provinces and most of La Pampa Province. The area is, in all, home to no more than a million people, who generally enjoy some of the nation's lowest poverty rates. The Humid Pampas grassland lies to the east, while the drier Argentine Espinál (thorny) grassland lies to the west. The soil tends to be sandier in this region than to the east, though both regions are characterized by their mostly minimal incline and frequent finger lakes. Generally more similar than not, these two biomes are mostly distinguished by their contrasting rainfall quantities, soil quality and land use; this section of the pampas typically sees about a third less rainfall (700 mm, 27 in) than the humid pampas. Flora Not unlike the more humid pampas to the east, this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arid Pampas Red
A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and morphogenesis, development of plant and animal life. Regions with arid climates tend to lack vegetation and are called Deserts and xeric shrublands, xeric or desertic. Most arid climates straddle the Equator; these regions include parts of Africa, Asia, Arid Diagonal, South America, Southwestern United States, North America, and Australia. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from Semi-arid climate, semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity. See also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
