Abstract. Climatic zone delimitation is useful for relating climate to the distributions and activities of flora and fauna on the earth’s surface. Many approaches have been used in defining climatic zones.
15 Ιαν 2015 · Introduction. The world’s semi-arid regions are expected to be among those most sensitive to future climate change and increasing intensity of land use. Thus, the future may not bode well for the two billion people who inhabit these environments.
For definition of semi-arid zones on a regional basis, it is necessary to stipulate lower limits of moisture adequacy which delimit the semi-arid zone from the arid, and upper limits of moisture adequacy that delimit the semi-arid zone from still moister subhumid regions.
12 Μαρ 2020 · The regions of the world where average precipitation is between one fifth and half of the potential plant water demand are termed ‘semi-arid’. They make up 15.2% of the global land surface, and...
17 Αυγ 2021 · As a proxy of global changes, knowledge of SD and diversity along climatic gradients is essential to determine the efforts needed for species conservation. Plant spectral diversity is an emerging approach used as a proxy for species diversity based on remote sensing.
Vegetation and climate characteristics of arid and semi-arid grasslands in North America and their biome transition zone. The objective of this study was to investigate the relationship among species richness, functional group composition, and climate for three sites representing the shortgrass steppe, the Chihuahuan….
Abstract. More than one third of the earth’s land surface (ca. 49 million km 2) is arid or semi-arid, receiving less than 400 mm annual precipitation, supporting more than 1.2 billion people, or 20% of the world’s population, a population that is now expanding at a far greater rate than the environment can support.
