Land Degradation. • The soil pore system as an indicator to quantify soil physical degradation SOIL STRUCTURE Definition Soil structure may be defined either as "the shape, size and spatial arrangement of individual soil particles and clusters of particles (aggregates)" or as "the combination of different types of pores with solid particles (aggregates)"., Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush ….

Aug 01, 2010В В· Types of environmental degradation Deforestation: Thus, deforestation is a serious type of environmental degradation. Soil erosion: Soil erosion can be defined as the destruction of the top layer of the soil as a result of natural or human activities. Soil erosion refers to the carrying away of soil. Norbu et al., (2000) give a general account of the land degradation types in Bhutan but do not pinpoint the most common types or their severity (degree of degradation). By applying the GLASOD definitions of degrees of degradation (Table 1 below) to our survey data, we estimate the degree to which the land is presently degraded

Soil degradation includes erosion, salinization (due to freshwater removal), soil loss following erosion after deforestation or overgrazing, “compaction and crusting (of soils), [which] can be caused by cattle trampling,” and waterlogging with impaired water movement (Oldeman et al., 1991).It was estimated in 1991 that there was 1.96 billion ha of land globally with soil … Land degradation is the temporary or permanent lowering of the productive capacity of land (UNEP, 1992b). It thus covers the various forms of soil degradation, adverse human impacts on water resources, deforestation, and lowering of the productive capacity of rangelands. This study takes the degradation of soil resources as its focus.

Apr 15, 2015В В· The main types of soil degradation in the Kura-Aras Lowland are irrigation-induced erosion, natural water and wind erosion, and salinization. Among 2098.8 thousand ha of agricultural land in the lowland, the areas of lands subjected to erosion and salinization reach 333.6 and 373.4 thousand ha, respectively. And soil is the bedrock of geography. The soil in an area is an indicator of the climate of that region, not to mention the history and formation of that region. It is a factor that influences the vegetation, wildlife, and human culture in that region. So let us find out more about soil and the types of soil in India in these Static GK Notes.

In this study, enantioselective degradation of dufulin in four types of soil (Guiyang silty loam, Nanning silty clay, Hefei silty clay, and Harbin silty clay) was investigated under sterile and nonsterile conditions. Pesticide residues in soil samples were extracted with acetonitrile.

be measured and used as an indicator for evaluating soil degradation under different land use systems [3]. Soil texture in the land use types is silt loam. The conversion of forest into cropland is known to deteriorate soil physical properties and making the land more susceptible to erosion since macro-aggregates are disturbed [4]. Soil degradation is the decline in soil quality caused by its improper use, usually for agricultural, pastural, industrial or urban purposes. Deserts are examples of extremely degraded soil areas, while the southern United States contains very fertile soil areas.

Soil Type: Soil Acidification Drop in soil pH Possible P, K, Ca & Mg deficiencies Decreased nodulation in legumes Reduces availability of nutrients & induces deficiencies Possible nitrate contamination of streams Nutrient depletion (Ca, Mg) Excessive N fertiliser Less likely in soils with limestone The droughts of 1970-2000 accelerated soil degradation and reduced per-capita food production (GoK 2002). More recent studies extrapolating on local п¬Ѓ ndings of spatial and temporal patterns of land degradation estimate it is increasing in severity and extent in many areas and that over 20 per cent of all cultivated areas,

Soil degradation is any type of problem that removes soil in an area or makes high-quality soil become poor. Careless agricultural practices, pollution and deforestation cause lots of soil degradation in the world. Several types of soil degradation exist and are a threat to natural forests and planted crops. Keywords: land use type, soil quality, soil degradation Introduction In Nigeria, non sustainable use of land has resulted in massive land degradation and soil infertility (Udoh et al, 2002). Assessing land use- induced changes in soil is essential for addressing agro-ecosystem transformation and sustainable soil productivity issues.

Soil Degradation Soil degradation is a human-induced or natural process which impairs the capacity of soil to function. As an example, in 3000 BC, the Sumerians built large cities in the deserts of Southern Mesopotamia. Using irrigation, they farmed the desert soils and created large food surpluses that made their civilization possible.

Soil degradation – a major threat to humanity Summary • Soil degradation needs to be recognised, alongside climate change, as one of the most pressing problems facing humanity. Solutions need to be developed and introduced which address both issues simultaneously.
