Conservation Farming in Zambia. CA produces minimal adverse impacts on ecosystems, reduces soil erosion, cuts down long-term production costs, and improves soil fertility (Haggblade and Tembo. Currently, 40% of soil in Africa is degraded. Degraded soil diminishes food production and leads to soil erosion, which in turn contributes to is particularly worrisome since, according to the UN's Food and Agriculture Organization, some 83% of sub-Saharan African people depend on the land for their livelihood, and food production in Africa will have to increase almost Author: Angela Thompsell.

Soil Erosion and Conservation provides a comprehensive treatment of the processes of soil erosion, the methods that can be used for their control, and the issues involved in designing and implementing soil conservation programmes.

Features of the third edition of this internationally recognised textbook include: New material on gully erosion, tillage practices, erosion risk assessment, use of /5(4). Book: Economics of soil degradation, erosion and conservation: a case study of Zimbabwe pp pp.

Abstract: Little is known about the cost of degradation and Cited by: Soils and soil erosion. Soil erosion involves the detachment of soil particles from larger aggregates (or Soil erosion and conservation in Zimbabwe book and the removal of the particles by flowing water and wind.

In the climatic conditions which prevail throughout most of Zimbabwe fluvial erosion is dominant, that is the effects of rain splash and run-off, both surface and subsurface. Soil Erosion, Conservation, and Rehabilitation - CRC Press Book Discusses the latest information regarding the processes and mechanisms responsible for runoff and erosion by water in arable lands--detailing state-of-the-art water and soil conservation methods.

Book Description. Discusses the latest information regarding the processes and mechanisms responsible for runoff and erosion by water in arable lands--detailing state-of-the-art water and soil conservation methods.

Elucidates the rehabilitation of agricultural lands depleted by human activity. Table of Contents. Part 1 Soil erosion by water: basic factors and processes in soil erosion - infiltration and seal formation processes, rainfall analysis, soil characteristics and aggregate stability, splash and detachment by waterdrops, slope, aspect and surface storage, the effect of surface cover on infiltration and soil erosion; forms of erosion - interill erosion, rill and gullies.

Soil conservation. Prevention of soil erosion is also called conservation of soil. The soil erosion can be prevented by the following ways: 1. Afforestation. Planting new trees and plants is afforestation.

We live because plants live. If the plants die, all living things will also die. Thus, whenever trees are cut down new trees should be planted. Soil erosion is the displacement of the upper layer of soil, it is one form of soil natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans.

This handbook explains the causes, processes, and consequences of soil erosion and depletion, and describes the major soil- and water-conservation measures which, when applied to the land in correct combinations, will greatly reduce or prevent soil erosion, improve fertility, and increase yields.

Soil conservation is an international concern. erosion impact from earthquakes is comparatively minimal mainly because these events are relatively rare. However, when earthquakes occur, massive amounts of soil, including crops and forests are affected in area hillsides and in surrounding areas.

Assessing soil erosion Although soil erosion has been taking place very slowly in natural. erosion studies in order to avoid damaging assumptions regarding soil erosion. This is against the background that soil erosion is an interdisciplinary problem and that there are challenges to soil conservation in practice.(Blaikie,;Blaikie and Bookfield,Elliot,).To this end, soil erosion should not be viewed in aFile Size: KB.

Conservation Agriculture is a farming system that promotes minimum soil disturbance (i.e. no tillage), maintenance of a permanent soil cover, and diversification of plant species.

It enhances biodiversity and natural biological processes above and below the ground surface, which contribute to increased water and nutrient use efficiency and to improved and sustained crop production.
