The role of forests and forestry in the prevention and rehabilitation of landslides in asia help to reduce soil erosion and can form an effective barrier against rock, debris and soil slips, as well as limiting landslide run-out distances.
The role of forest stand density in controlling soil erosion: can be insured by stand density control, is needed to reduce soil loss the present study plays an important role in clarifying technical processes related to soil erosion, while it helps linking these. Trees are used extensively to reduce the risk of landslides and to prevent rivers from washing away soil vegetation planted along rivers beautifies the banks and plays an important role in the protection of river ecosystems. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas.
Soil erosion is global problem 1/3 world’s arable land lost since 1950 most in asia, africa, s america 13-18 t/a/yr 30% of us farmland abandoned erosion salinization water-logging 90% of us cropland losing soil faster than it is replaced 1 t/a/yr pimentel et al, 1995. Soil erosion is a natural process of excessive influence of water and wind on the upper fertile layer it's aggravated by wrong human agricultural activity (destruction of vegetative cover by domestic animals or deforestation. Strategies for erosion control or the fight against soil erosion: soil erosion is a constant threat to the stability of agro ecosystems-saxena nb the protection of cultivated land against erosion involves a combination of civil engineering and biological techniques. The role of trees and forests in healthy watersheds managing stormwater, reducing flooding, and improving water quality this leads to flooding, stream bank erosion, widening of streams, sediment deposited in streams, a loss of fish habitat, and decline in water quality trees and forests play an incredible role in reducing storm water. Edit item water & soil forests play a key role in the protection of the world's water resources and in the global water cycle in maintaining high water quality, forests make their most significant contribution to the supply of water.
The development and implementation of measures which promote the reduction of the impacts of forest fires on soils is imperative and should be part of any strategy for forest and soil preservation. Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-affects of forest fire vegetation: the simplest and most natural way to prevent erosion is through planting vegetation. Forest hydrology, the authors summarize what is known about the forest's influence on the water resource, particularly the effects of current forestry practices.
Maintaining groundcover to reduce erosion and sustain production agfact p2114, january 2005 groundcover is important for soil health and assists in weed control groundcover is deﬁned as any material on or role of groundcover. Because soil erosion is such an important issue to farmers, any practice that will help prevent water runoff or helps to maintain the strength of the soil structure will be beneficial. A forest is a large area of land covered with different types of vegetations, large trees, vines, a few shrubs, mosses and wild orchids forests are important in preventing soil erosion. Water-retention potential of europe's forests this report provides for the first time a european overview of the role of forests in water retention, based on the water accounts production database developed at the eea the results represent 287 sub-basins hosting more than 65 000 catchments across europe.
The effects of forest in controlling gully erosion in this way, we can effectively control soil erosion and produce greater economic benefit this emphasises the important role of the forests in the gullies, after the forest on the flat ridges and the slopes has been destroyed the. By international journal of forest, soil and erosion (ijfse) the current study was carried out in order to investigate the effect of periodic application of wastewater on some soil chemical properties and distribution and migration of cu and zn in soil profile. The effects of forest management on erosion and soil productivity recent studies on erosion and its control on forest lands in the united states in: richard, f (ed) management on. Erosion-prone soils and run-off pathways, will help control or reduce the risk of soil erosion and shallow landslides forest restoration in dryland areas is vital for soil protection.
Tree cover plays an important role in reversing soil erosion, and additionally preventing landslides in hilly regions in a study done in the alaknanda valley of the uttarakand himalayas, it was found that the landslide occurrence for open and degraded pine forests was 2-3 times higher than for healthy pine forests. Deforestation, clearance, or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use examples of deforestation include conversion of forestland to farms, ranches, or urban use the most concentrated deforestation occurs in tropical rainforests about 31 percent of earth's land surface is covered by forests.
Tree roots help prevent landslides on steep slopes and stream bank erosion but they don’t stop erosion on moderately sloping hillslopes in forests, the soil surface is usually protected by a layer of mulch from decaying vegetation as well as a variety of surface growing plants. This activity teaches students about the role of plant growth in protecting the earth from soil erosion students observe and discuss examples of soil erosion in photographs and in their own environment realize that plant roots help prevent soil erosion forest fires are relatively common on the steep mountain slopes, stripping. A range of measures have been used to control or prevent erosion on new zealand’s farmland some were adopted from other countries such as the usa, some were learnt by trial and error, and others developed from research. Soil erosion control: soil erosion or loss results from the action of wind and water on unprotected soils the forest canopy, roots and leaf litter all have a role in controlling soil erosion.
