Soil erosion by water in the tropics. Honolulu, Hawaii: College of Tropical Agriculture and Human Resources, University of Hawaii Honolulu, Hawaii: College of Tropical Agriculture and Human Resources, University of Hawaii. Abstract. ABSTRACT Soil erosion hazard in tropical Africa is a serious threat towards sustained productivity. The available basic research information on soil, climate, and land use is rather sketchy and indicates that the severity of the erosion hazard may be attributed to soil characteristics, low soil loss tolerance, and climatic factors that lead to accelerated soil erosion .
Soil erosion is the removal of soil material, generally from the surface, by water (striking raindrops and downslope runoff) or by wind (deflation of loose particles and their transport as dust). Erosion is a natural process that occurs inevitably and continuously. Rainforests reduce erosion By Rhett A. Butler April 1, Read more. The roots of rainforest trees and vegetation help anchor the soil. When trees are cut down there is no longer anything to protect the ground, and soils are quickly washed away with rain. The process of washing away of soil is known as erosion.
What is Soil Erosion? Soil erosion is a process that involves the wearing away of the topsoil. The process involves the loosening of the soil particles, blowing or washing away of the soil particles, and either ends up in the valley and faraway lands or washed away to the oceans by rivers and streams. A text on the problem of soil erosion, covering the principles and processes of wind and water erosion, with emphasis on the tropics. Since soil erosion is the single largest problem in maintaining Read more.

No where is soil erosion more of a reality than in the tropics. In addition to the aggressive climatic conditions, these regions are also characterized by high population densities that are leading to rapidly increasing use of marginal lands. The problem of soil erosion is as old as history.
Its significance, however, is rapidly increasing. As population increases, the area of cropland for each person shrinks. Between andworld population increased by 59% and the area of cereals expanded by 21 %.

But soil erosion (one component of land degradation) jeopardizes the sustainable delivery of these services worldwide, and particularly in the humid tropics where erosion potential is high due to heavy by: Erosion is a natural process of detachment of soil particles and their transport and deposition at distant places by natural agents such as water, wind, glacier, and gravity.
Detachment of soil particles from aggregates primarily by raindrops and flowing water and their transport by runoff water are involved in soil erosion by by: Soil erosion by water is the detachment, transport and deposition of soil particles by flowing water. After intense rainfall and runoff events, it can take the form of concentrated flow.
The effects are less conspicuous following regular rainfall events, where small amounts of soil are removed. Soil erosion is a key form of soil Size: 1MB.

Regions located in the tropical climate zones suffer the greatest rainfall-related soil erosion, according to a study published in Scientific Reports, an online open access scientific mega journal According to the analysis, the risks can be managed through good agricultural practices like reduced tillage, cover crops, grass margins and contour.
Soil and water being splashed by the impact of a single raindrop. Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion.
The papers in this volume deal with the degree and extent of soil erosion in tropical and sub-tropical regions. Three papers discuss past efforts and experience with soil conservation and their applications to today's conservation practices and policies.
Views, experiences and examples from Zambia and Lesotho are presented. One paper highlights the potential of agroforestry as a soil. Soil Erosion by water, Soil Erosion by air. This feature is not available right now.
