Causes And Effect Of Erosion

Causes And Effect Of Erosion

Abstract

This exploration work was designed to examine the causes and effect of soil corrosion in Ovia North East Local Government Area of Edo State. Five( 5) exploration questions were formulated and questionnaires were administered to one hundred( 100) repliers in order to gather data for the exploration. Results showed that agrarian conditioning lead to soil corrosion, indecorous soil operation cause corrosion, deforestation lead to corrosion etc. Recommendations were made and it include that;

Sustainable soil operation systems must be developed to reduce farther declination and restore the productivity of the eroded land.

The operation options to reduce the soil loss are to apply conservation measures and/ or to change the crop to be planted.

Soil conservation styles including sundecks and bunds as well assemi-permeable structures like lawn strips should be used as walls to holdback runoff and deposition carried with it.

Agronomic measures like figure furrowing have the advantage to reduce runoff and soil loss.

Preface

Background To The Study

corrosion is honored as one of the world’s most serious environmental problems( Pimentel etal., 2005, Shiferaw and Holden, 2009). Encyclopedically, about 80 of the current declination of agrarian land is caused by soil corrosion( Angima etal., 2003). corrosion by water, at a global scale, is the main soil declination process in agrarian areas( Bewket and Sterk 2002). It generates strong environmental impacts and major profitable losses from dropped agrarian product and from out- point goods on structure and water quality by sedimentation processes( Zinabu etal., 2002; Daba, 2003; Haregeweyn etal., 2005; Amsalu etal., 2007).

corrosion creates severe limitations to sustainable agrarian land use, as it reduces on- ranch soil productivity and causes food instability( Tadesse, 2001 Sonneveld, 2002; Beshah, 2003, Moges and Holden, 2006, Bewket, 2007). In utmost developing countries mortal exertion triggers these losses( Mohammad etal., 2001, Belyaev etal., 2004, Bewket and Sterk, 2005, Hurni etal., 2005). This is associated with rapid-fire population growth, shy attention to the introductory natural coffers( soils, water and foliage), and the need to maximize product to meet the requirements of the growing population( Shiferaw and Holden, 2009, 2000, Bewket, 2002, Feoli etal., 2002). This situation is more serious in poor developing countries where subsistence product predominates. The average planter who cultivates one hectare of food crops and keeps some beast, is currently dependent on natural conditions and can not tolerate farther deterioration of soil productivity( Sonneveld and Keyzer, 2003). adding population, violent land civilization, unbridled grazing, and deforestation frequently lead to, or complicate, soil corrosion( Tadesse, 2001 and Bewket, 2002). These factors undermine agrarian productivity and frustrate profitable development sweats, especially in developing countries where there’s heavy land dependence( Shiferaw and Holden, 2000) in low external- input husbandry systems.

Statement Of The Problem

corrosion is considered as one of major land declination process in Ovia North East Local Government Area of Edo State which is also the main source of environmental deterioration. It creates negative impacts on agrarian product, structure and water quality( Vrieling, 2006). corrosion is also the natural miracle( geological process) which is caused by natural force; it can be more accelerated when the process is told by mortal conditioning( mortal- convinced corrosion). It’s considered that the accelerated corrosion is a serious global problem and extensively honored( de Graaf, 2006). With the accelerated corrosion, it can affect agronomic/ biomass productivity( on- point effect) and flooding, sedimentation of budgets, siltation of husbandry field and drop of water quality downstream( off- point goods). The two important agents of corrosion are wind and water( Hudson, 2006).

The study area is located in Ovia North East Local Government Area, Edo State. This area is an ferocious agrarian areas in Edo State for times now. The conversion of the tropical rain timber to agrarian system has been taking place. With the adding population, the civilization in the mountainous area has been taking place. The primary timber is replaced by the sludge, plantain, paw- paw, yams, and other crop types. The junking of natural timber and foliage cover in steep pitch and followed by indecorous land use practices have led to the colorful land declination problems in the area. Each time during the stormy season a lot of clod is eroded and the agrarian lands are affected. On the other hand; the eroded soil and sediments which are transported by the face runoff affect the downstream civilization land.

Purpose Of The Study

The purpose of this study is to have clear understanding of the causes and effect of corrosion in Ovia North East Local Government Area, Edo State.

The specific objects are

1) To identify the practices that accelerates corrosion in the study area.

2) To bandy the perception of the people in relations to the effect of corrosion on the agrarian capabilities and performance of the communities in Ovia North East.

Exploration Question

i) Do agrarian conditioning lead to corrosion?

ii) Does deforestation lead to corrosion?

iii) Does indecorous soil operation cause corrosion?

iv) Is urbanization a major effect on corrosion processes?

v) Does climate change contribute to corrosion problem?

Significance Of The Study

This study helps to know the extent at which the occupant of Ovia North East share in unhealthy conditioning that lead to corrosion in the area. It’ll also give the information about the major causes of corrosion in the study area.

It’ll enlighten the general public on the ways corrosion can be control/ reduced in the study area.

It’ll serve as a source of information to government and the ministry of surroundings on way to take in diving the imminence of corrosion in the study area. It’ll also give information to the original government authority on the causes and effect of corrosion and ways to working the problem of corrosion in Ovia North East.

Compass Of The Study

The study is set out to determine the causes and effect of corrosion in Ovia North East Local Government Area of Edo State. thus, the study is confined to five communities in the area of study. The communities include Ekiadolor, Ovbiogie, Iguedaiken, Iguikhinmwin and Iyowa community. Repliers include growers, scholars, preceptors, civil retainers, youths, and motorists.

Description Of Terms

Soil corrosion- “ The wearing down of the land face by physical forces similar as downfall, runoff water, wind, ice, temperature change, graveness.

Wind corrosion Is a major geomorphologic force, especially in thirsty andsemi-arid regions.

Exfoliation Is a type of corrosion that occurs when a gemstone is fleetly hotted up by the sun.

foliage Is the interface between the atmosphere and the soil.

Deforestation The nonstop felling of trees without potting.
