At the same time in the semiarid karst savanna of Texas, USA, woody plant encroachment has been found to improve soil infiltrability and therewith groundwater recharge. [63] At the same time a conversion of rangelands to redcedar woodland has been modeled to result in a 20-40% reduction in streamflow and therewith the amount of water available.
A tree savanna at Tarangire National Park in Tanzania in East Africa A grass savanna at Kruger National Park in South Africa. A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
Overgrazing is a main contributor to degradation of grasslands worldwide. It reduces vegetation cover and degrades topsoil, leading to soil compaction from trampling by wildlife.
View of bush encroached land at the Waterberg Plateau Park in Otjozondjupa Region, Namibia. Woody plant encroachment (also called woody encroachment, bush encroachment, shrub encroachment, shrubification, woody plant proliferation, or bush thickening) is a natural phenomenon characterised by the area expansion and density increase of woody plants, bushes and shrubs, at the expense of the ...
Crunch time came in 1996, when the six founders moved to Missouri due to its affordable land and a lack of restrictive zoning and building codes. The ambitious group purchased 280 acres of land ...
The results of the initiative showed that although there is not enough available land in Canada to completely offset the country's GHG emissions, afforestation can be useful mitigation technique for meeting GHG emission goals, especially until permanent, more advanced carbon storage technology becomes available.
Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
Much of the soil has rocks or clay from volcanic activity. Other causes include erosion, desertification, and deforestation. Another source of soil degradation is the improper management of waste, lack of facilities and techniques to handle waste lead to the dumping of waste in soil, therefore causes soil degradation by process such as leaching.
