“…In addition, sediments contain chemicals that can pollute waterways, increasing nitrogen and phosphorus levels in water bodies, causing eutrophication, increasing the cost of electricity generation and water capture for supplying urban centers and causing a shortage of water resources for irrigation-dependent regions (Pimentel & Kounang, 1998). A further consequence of soil degradation is the release of CO 2 into the atmosphere (Lal, 2007;Salvati & Zitti, 2009). The costs of all these effects can also be quantified.…”

The aim of this study was a survey of the estimated costs of soil erosion, an issue of fundamental importance in view of the current worldwide discussions on sustainability. A list was drawn up of research papers on erosion (on-site and offsite effects) and their respective costs. The estimates indicate the amount of resources spent in the process of soil degradation, raising a general awareness of the need for soil conservation. On-site costs affect the production units directly, while off-site costs create a burden borne by the environment, economy and society. In addition, estimating the costs of soil erosion should be effective to alert the agricultural producers, society and government for the need for measures that can be implemented to bring erosion under control. Among the various estimates of soil erosion costs between 1933 a 2010, the highest figure was 45.5 billion dollars a year for the European Union. In the United States, the highest figure was 44 billion dollars a year. In Brazil, estimates for the state of Paraná indicate a value of 242 million dollars a year, and for the state of São Paulo, 212 million dollars a year. These figures show, above all, that conservation measures must be implemented if crop and livestock farming production are to be sustainable. Index terms: soil degradation, on-site and off-site losses, sustainable development. RESUMO: OS CUSTOS DA EROSÃO DO SOLO

“…The same procedure refers to the process of classifi cation by interpreting different layers of information. In fact, classifi cations simplify data by summarizing the values of different attributes within a limited number of classes (Salvati and Zitti 2009). The interpretation of data calls for uniform classifi cations with data organized into reference systems or when different types of ecosystems are compared, in a simple and acceptable way (Salvati et al 2013).…”

“…Among numerous models, MEDALUS model (MEditerranean Desertifi cation And Land USe), developed by the European Commission is of great signifi cance (Brandt and Thornes 1996). MEDALUS model is widely used in the European countries as a successful tool for the detection of most endangered areas in terms of land degradation (Salvati and Zitti 2009, Contador et al 2009, Santini et al 2010, Vieira et al 2015. This model has been largely tested in the Mediterranean basin countries and has shown good results , Geeson et al 2002, Basso et al 2012.…”

This paper studies the assessment of sensitivity to land degradation of Deliblato sands (the northern part of Serbia), as a special nature reserve. Sandy soils of Deliblato sands are highly sensitive to degradation (given their fragility), while the system of land use is regulated according to the law, consisting of three zones under protection. Based on the MEDALUS approach and the characteristics of the study area, four main factors were considered for evaluation: soil, climate, vegetation and management. Several indicators affecting the quality of each factor were identifi ed. Each indicator was quantifi ed according to its quality and given a weighting of between 1.0 and 2.0.ArcGIS 9 was utilized to analyze and prepare the layers of quality maps, using the geometric mean to integrate the individual indicator map. In turn, the geometric mean of all four quality indices was used to generate sensitivity of land degradation status map. Results showed that 56.26% of the area is classifi ed as critical; 43.18% as fragile; 0.55% as potentially affected and 0.01% as not affected by degradation. The values of vegetation quality index, expressed as coverage, diversity of vegetation functions and management policy during the protection regime are clearly represented through correlation coeffi cient (0.87 and 0.47).

“…However, it should be noted that except for some microclimate zone considering as spots, production of forest land use was higher than range and desert land use because of the vegetation amount (Barnes et al, 1998). On the other hand, given the definition of land degradation include reduction of productivity and ecosystem functioning in a long-term period (Bai et al, 2008), this is often related to the reduction in plant cover and biomass (Wessels et al, 2007;Salvati and Zitti, 2009). With these descriptions and based on the map of the different land uses average NPP (Fig.…”

“…Drylands (arid, semiarid and dry subhumid areas) cover approximately 41 % of the Earth's surface and approximately 10 to 20 % of these regions are experiencing degradation and desertification processes, resulting in a decline in agricultural productivity, loss of biodiversity and the breakdown of ecosystems (Keesstra, 2007). Considering the widespread and threatening aspects of desertification in locations all around the world, many researchers have tried to analyze it by means of experimental models and methods (Prince et al, 1988;Ladisa et al, 2011;Liu and Yang, 2003), remote sensing methods (Symeonakis et al, 2014;Helldén and Tottrup, 2008;Hill et al, 2008;Rasmussen et al, 2001) and modeling (Nicholson et al, 1998;Salvati and Zitti, 2009;Santini et al, 2010).…”

Desertification of forest, range and desert in Tehran province, affected by climate change

Abstract. Climate change has been identified as a leading human and environmental crisis of the twenty-first century. Drylands throughout the world have always undergone periods of degradation due to naturally occurring fluctuation in climate. Persistence of widespread degradation in arid and semiarid regions of Iran necessitates monitoring and evaluation. This paper aims to monitor the desertification trend in three types of land use, including range, forest and desert, affected by climate change in Tehran province for the 2000s and 2030s. For assessing climate change at Mehrabad synoptic station, the data of two emission scenarios, including A2 and B2, were used, utilizing statistical downscaling techniques and data generated by the Statistical DownScaling Model (SDSM). The index of net primary production (NPP) resulting from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images was employed as an indicator of destruction from 2001 to 2010. The results showed that temperature is the most significant driving force which alters the net primary production in rangeland, forest and desert land use in Tehran province. On the basis of monitoring findings under real conditions, in the 2000s, over 60 % of rangelands and 80 % of the forest were below the average production in the province. On the other hand, the longterm average changes of NPP in the rangeland and forests indicated the presence of relatively large areas of these land uses with a production rate lower than the desert. The results also showed that, assuming the existence of circumstances of each emission scenarios, the desertification status will not improve significantly in the rangelands and forests of Tehran province.
