Essay on Soil Erosion Environment Article shared by: Meaning of Soil Erosion: All land use activities, particularly those which are poorly managed, involve destruction or disturbance, to a greater or lesser extent, of natural and semi-natural ecosystems. Almost invariably, however, it is those ecosystems, in equilibrium with their environment, which offer most effective protection to the soil that supports them.
Physical resources assessment in a semi-arid watershed: An integrated methodology for sustainable land use planning The study demonstrates the application of geospatial technologies to evaluate physical resources of semi-arid watersheds and presents a comprehensive methodology applicable elsewhere.
The selected Andipatti watershed, located in Theni The selected Andipatti watershed, located in Theni district in the State of Tamil Nadu Indiais known for agricultural activities; however, haphazard planning, management practices and inadequate investments result in land and water resource degradation.
Since most of the agricultural lands in developing countries are similar to these conditions, the present study is attempted as a case to develop a framework to assess the land and water resources potential, utilisation level and land suitability for agriculture; and to evolve better management strategies.
The physical characteristics of the watershed were studied based on in-situ, remotely sensed and secondary data sources.
Thematic layers were generated with the combination of remote sensing, image processing and GIS techniques. In order to characterize and quantify the watershed based on soil erosion and surface runoff rates, the revised universal soil loss equation RUSLE and natural resources conservation services curve number NRCS-CN were utilized.
Data on water levels and geochemistry of water samples, collected from 36 dug wells were also utilized for this study. The storie index has been used to assess the productivity of land using profile and textural characteristics of the soil.
Keeping Food and Agricultural Organisation FAO guidelines as a reference, as many as homogenous micro-land units were prepared.
The physical land qualities and characteristics of each land unit were compared with the requirements of 13 major crops of the study area and suitable crops for each unit were identified. The individual suitability classes of all crops were compared using logical analysis and suitability crops for each land unit were determined under irrigated and rain-fed conditions.
In order to integrate the results of these analyses and to suggest sustainable agricultural development measures, the study area was divided into 44 micro-watersheds. All the results of land and water resources assessment were compared and a proposed land use map was prepared.
The findings suggest strategies for coping with sustainable agricultural practices for the present study area and provide an integrated methodology for future assessments elsewhere, especially in the developing countries.Soil erosion is a natural process, occurring over geological time, and indeed it is a process that is essential for soil formation in the first place.
With respect to soil degradation, most concerns about erosion are related to accelerated erosion, where the natural rate has been significantly increased mostly by human activity.
Soil erosion is a process of detachment and transportation of soil by natural agencies of water and wind. Factors Influencing Soil Erosion: There are many factors which influence the process of soil erosion; these are discussed below: 1.
Essay on Soil Erosion and The Erosion of Civilizations - Soil erosion began with the dawn of agriculture, when people abandoned their hunter-gatherer lifestyles and began using the land for intensive agriculture, thus removing the protective vegetation cover .

Today's main focus is energy and environmental concerns. Soil erosion is significant, however, for various reasons. Currently, the Mississippi River is altering it natural course due to soil deposits from the northern 3/5(5).
Rainfall: Precipitation is the most forceful factor causing erosion. Essay on Soil Erosion and The Erosion of Civilizations - Soil erosion began with the dawn of agriculture, when people abandoned their hunter-gatherer lifestyles and began using the land for intensive agriculture, thus removing the protective vegetation cover .
Soil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely.
Erosion can be defined as the removal of soil particles by the motion of wind or water. Soil erosion is considered to be one of the major concerns of agriculture throughout the world today. The misuse of land, mismanagement of farm land, felling of trees, overgrazing, poor soil and water management are all practices that contribute to soil erosion. Essay # 6. Measurement of Soil Erosion: Those designed to determine soil loss from relatively small sample areas or erosion plots often as part of an experiment and those designed to assess erosions over a larger area such as a drainage basin. In erosion plot, a standard size of 22 m long and m wide are used. Soil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. Soil deterioration and low quality of water due to erosion and run off has often become a severe problem around the world.
Included: environment essay india essay content. Preview text: The removal of soil by running water and wind is known as soil erosion. The soil-forming process and the erosional process of running water and wind are continuous. Generally, there is a balance between these two processes.
The rate of . Soil erosion modeling is able to consider many of the complex interactions that influence rates of erosion by simulating erosion processes in the watershed. Soil erosion model is a necessary tool to predict excessive soil loss and to help in implementation of erosion control strategy .
