Theme 4 — Economic Development case studies A. Pests and disease tend to foster if one crop is left in an area for too long. To then make a comparison of rates of soil erosion and land degradation between these two agricultural sectors on the premise that degradation or lack of it, is the result of either good or bad husbandry makes little sense. Small dams are likely to fill with sediments within 15 years of construction and even the larger irrigation schemes are being affected adversely by siltation problems. Whereas in one system the link between the owners and the land had an ecological base, that is, the produce of the tribal area was the main substance of the tribe, in the other the land may have no ecological significance to the owners, being merely one of a series of potential sources of monetary income. Boscastle is built on a very narrow floodplain, and has grown much bigger than the original settlers could have envisaged when they were first attracted to its
On the other hand, the commercial farming areas are on prime land, with very stable clayey soils. Resistive forces are those which help overcome the applied energy forces and relate mainly to soil properties. Soil erosion tends to be high in sugarcane fields An presentation created with As you can see from the previous section, good, fertile soil is imperative to our survival. Consider this a study guide: A decline in resources status, in turn has adverse effects on living standards.
GAIA Case Study Zimbabwe: Soils and soil erosion
It is casee interesting to study the distribution of erosion according to the main tenure systems. Posted by Captain Chemistry at 8: Soil erosion – overcultivation and overgrazing have damaged the vegetation in places, Posted by Captain Chemistry at Land-use in Dry Tropical Savannas Soils and soil erosion Soil erosion involves the detachment of soil particles from larger aggregates or peds and the removal of the casse by flowing water and wind.
Employment – tourism has generated jobs, improving the living standards for local communities. Kenya is located in East Prior to above-mentioned study, a soil erosion model, known as the Universal Soil Loss Equation, Soil erosion in developing countries: Here you will read about each.
Large scale erosion forming a gully system Humans have not always done well or realized the importance of maintaining stjdy soil Over-watering is done at many crops areas and results in flooded fields and eroded soils.
Soil erosion arising from poor agricultural practice has been a problem since the s. Loss of traditional cultures – the Masai’s way of life and traditional farming methods have been disrupted by the setting lddc of the Serengeti National Park. Pests and disease tend to foster if one crop is left in an area for too long.

Using a named and located case study — explain the causes of soil An presentation created with Geometry of Downstream A case study from Gumti Any area of land will support in perpetuity only a limited number of people and if this limit is exceeded without a compensating change in the system of land usage, then a cycle of degenerative changes is set in motion, which must result in deterioration or destruction of the land.
Carrying capacity changes with ecological regions, seasonal and within season variations.

As poverty becomes worse, spil the ability to effect changes in land use to reverse the cycle of degenerative changes is stidy. Whereas in one system the link between the owners and the land had an ecological base, that is, the produce of the tribal area was the main substance of the tribe, in the other the land may have no ecological significance to the owners, being merely one of a series of potential sources of monetary income.
Soil erosion under a successional agroforestry sequence: It is slowly being accepted that the definition of land degradation are flawed. No-till methods aerate the soil without tillage, and methods that decrease the amount of tillage are recommended for soil health.
