“…The settlement expansion on agricultural and forest land is affecting the humans by exposing forest ecosystems and negative impacts of habitat destruction within the forest ecosystem (Stimson et al, 2005). The improper land use is regarded as one of the chief agents of land degradation, which has previously been observed by various researchers (Biro et al, 2013;De Souza et al, 2013;Pallavicini et al, 2014;Mohawesh et al, 2015).However, since settlements and barren land exhibit similar spectral reflectance, slight mixing may have occurred between the two LULC classes. Zubair (2006) conducted the evaluation of change detection in land use and land cover of Ilorin and its Environs in Kwara State, Nigeria and ultimately concluded that the rapid growth in built-up land was one of the reasons of changing the land use and land cover.…”

“…The degradation of soil happens not only as a result of interaction between physico-chemical and biological factors comprising topography, soil properties and climatic features (Brevik et al, 2015;Taguas et al, 2015), but also includes human factors, land use management practices (Khaledian et al, 2013;Camprubi et al, 2015;Costa et al, 2015;Cerda et al, 2016). Improper land use practice has been attributed as one of the major causes of land degradation by various researchers (Biro et al, 2013;De Souza et al, 2013;Pallavicini et al, 2014;Mohawesh et al, 2015).The resilience and stability of landscape are affected to a great extent by the soil system which in turn affected by the inherent balance between inputs and nutrient loss and carbon (Amundson et al, 2015).…”

Abstract. Land degradation leads to alteration in ecological and economic functions due to decrease in productivity and quality of the land. The aim of the present study was to assess land degradation with the help of geospatial technology – Remote Sensing (RS) and Geographical Information System (GIS)) in Bathinda district, Punjab. The severity of land degradation was estimated by analysing the physico-chemical parameters in the laboratory and correlating them with satellite based studies.The results revealed that the soils in the study area were exposed to the salt intrusion which could be mainly attributed to irrigation practices in the state of Punjab. Most of the soil samples of the study area were largely found slightly or moderately saline with a few salt-free sites. Further, majority of the soil samples were calcareous and a few samples were alkaline or sodic in nature. A comparative analysis of temporal satellite datasets of Landsat-7 ETM+ and Landsat-8 OLI_TIRS of the year 2000 and 2014 respectively, revealed that the water body showed a slight decreasing trend from 2.46 km2 in 2000 to 1.87 km2 in 2014; while, the human settlements and other built-up areas expanded from 586.25 km2 to 891.09 km2 in a span of 14 years. The results also showed a decrease in area under barren land from 68.9847 km2 in 2000 to 15.2602 km2 in the year 2014. Significant correlation was observed between the Digital Number (DN) of near Infrared band and pH and EC. Therefore, it is suggested that the present study can be applied to projects with special relevance to soil scientists, environmental scientists and planning agencies that can use the present study as a baseline data to combat land degradation and conserve land resources in an efficient manner.

“…Methods of evaluating landfill site locations must follow es- tablished regulations. There are many methods used throughout the world to determine appropriate landfill sites that can found in the literature (Alexakis and Apostolos, 2014;Rezazade et al, 2014;Moeinaddini et al, 2010;Sumathi et al, 2007). Two research methods -Minnesota Pollution Control Agency method and regional screening guideline -were used for suitability evaluation of the current Tonekabon landfill site.…”

Abstract. Open dumping is the common procedure for final disposal of MSW in Iran. Several environmental pollutions and land degradation have caused because of poor planning, insufficient financial resources, improper organizational chart for MSW management system, and the lack of rules, guidelines and regulations. In Iran standards and regulations of environmental issues are not perfectly attended, evaluation an open dumping can show existing restrictions and troubles in these areas. So recognition of the municipal solid waste landfill state is required to prevent the increase of environmental problems and decrease the negative environmental impacts. The suitability of Tonekabon existing municipal landfill site in the west area of Mazandaran province, located in north of Iran, and the south coast of the Caspian Sea is the significance of the present study as a case study of land degradation. In order to carry out this evaluation, two guidelines are used. After reviewing all the considered criteria in each of the guidelines, the authenticity of the deposit site of the study area and also the entire city was examined; and eventually the appropriate areas were identified. The conclusion of the results indicated the incoherence in appropriateness of the existing landfill site, with two mentioned methods and field work.

“…For the applicability, each desirable model of soil erosion rate assessment should satisfy specific conditions of universal acceptability; reliability; robustness in nature; ease of use with minimum data set; and ability to take account of changes in land use, climate and conservation practices [2] . Apart from modeling by prediction, direct soil erosion measurement involves the use of big containers to harvest runoff but with poor success [8,9].…”

Soil erosion has been widely measured using different approaches based on models, direct runoff and sediment collections. However, most of the methods are, poorly applied due to the cost, the accuracy and their tedious nature. This study aimed to develop and test a new method for runoff characterization, which may be more applicable and adaptable to different situations of soil and crop management. An experiment was carried out on runoff plots under different cropping systems (sole maize, sole soybean and maize intercropped with soybean) and soil amendments (NPK, Biochar, NPK + Biochar and Control) in the Semi-deciduous forest zone of Ghana. The study was a two-factor experiment (split-plot) in which cropping systems constituted the main plot whereas soil management the subplot. To assess the quality of the method, different statistical parameters were used: p-values, coefficient of determination (R²), Nash-Sutcliffe efficiency (NSE), root mean square (RMSE) and, root square ratio (RSR). The NPK + Biochar under each cropping system reduced surface runoff than all other treatments.At p < 0.001, R² ranged from 0.88 to 0.94 which showed good accuracy of the method developed. The dispersion between the predicted and observed values was low with RMSE varying from 1.68 to 2.66 mm which was less than 10 % of the general mean of the runoff. Moreover, the low variability between parameters was confirmed by the low values of RSR ranging from 0.38 to 0.46 (with 0.00 ≤ RSR ≤ 0.50 for perfect prediction). NSE values varied from 0.79 to 0.86 (≥0.75 being the threshold for excellent prediction). Though the sensitivity analysis showed that the method under high amount of runoff (especially on bare plots) was poorly adapted, the dimensions of runoff plots could be based on runoff coefficient of the region by analyzing the possible limits of an individual rainfall amount of the site. The findings provide alternative approach for monitoring soil degradation.
