Saxaul is planted on a large scale in the afforestation of arid areas in China. Being highly drought-resistant, it has played an important role in the establishment of shelter belts and the fixation of sand dunes as a counter to desertification. [7] [8] The thick bark of the saxaul tree stores water.
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
Furthermore, they consider that a huge part of the Sub-Saharan area covering around 40 countries on the continent is land having arid conditions. Arid and semi-arid lands have much higher evapotranspiration rates as compared to the precipitation along with high air temperature mainly during dry seasons, high and almost continuous isolation ...
Afforestation is the establishment of a forest or stand of trees in an area where there was no recent tree cover. [1] There are three types of afforestation: natural regeneration, agroforestry and tree plantations. [2] Afforestation has many benefits.
Dryland farming caused a large dust storm in parts of Eastern Washington on October 4, 2009. Courtesy: NASA/GSFC, MODIS Rapid Response [1]. Dryland farming has evolved as a set of techniques and management practices to adapt to limited availability of water, as in the Western US and other regions affected by climate change for crops such as tomato and maize.
In suitable environments, such as the Daintree Rainforest in Queensland, or the mixed podocarp and broadleaf forest of Ulva Island, New Zealand, forest is the more-or-less stable climatic climax community at the end of a plant succession, where open areas such as grassland are colonised by taller plants, which in turn give way to trees that ...
Aridisols (or desert soils) are a soil order in USDA soil taxonomy. [1] Aridisols (from the Latin aridus, for "dry", and solum) form in an arid or semi-arid climate.. Aridisols dominate the deserts and xeric shrublands, which occupy about one-third of the Earth's la
Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher densities and areas of trees, with largely closed canopy, provide extensive and nearly continuous shade are referred to as forest.
