While the nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation. Besides‚ failure of rains‚ floods‚ depopulation and loss of cattle caused by famine and pestilence‚ disturbance caused by war and interference with or change

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

1. INTRODUCTION The stability and life of any structure – a building‚ an airport‚ a road‚ dams‚ levees – depend on the stability‚ strength‚ and deformation of soils.[1] Unfortunately‚ due to the uncertainties of the world’s natural materials‚ the study of geotechnical engineering‚ and soil mechanics in particular‚ is both challenging and necessary. The following report is a compilation of the results acquired as a result of two laboratories performed by Group 13 at McMaster University on February

Tutor: Date: Foundation Engineering Soil exploration obtains information about the subsurface parameters and conditions at the proposed Soil exploration as part of site investigation. In general‚ it deals with determining the suitability of the site for proposed construction. This consists of determining the profile of the soil deposits at and near the site. It mainly consists of taking the soil samples and checking the engineering properties of the soil and testing it in Situ. It then gets to

Soil erosion is a major concern in the southeastern region of Nigeria due to high population densities and farming techniques‚ which has resulted in the presence of numerous gullies. While gullies are found all around the world‚ the existence of gullies in Nigeria is regarded as one of the worst environment disasters‚ having negative implications on the environment and the quality of life for humans and other species (Adetona & Ezezika‚ 2011; Ajaegwu & al‚ 2010). Large quantities of soil in Nigeria

“Sons-of-the-Soil” and Local Insurgencies ABSTRACT One explanation for localized armed conflicts is competition between the original inhabitants of an area and more recent settlers‚ including both migrants from the same country and from abroad. As of yet‚ this explanation has not been thoroughly scrutinized‚ partly due to the lack of disaggregated data on violence needed to properly examine the hypothesis. Hence‚ this paper applies the idea of such “sons-of-the-soil” dynamics to
