“…In the Yangou catchment, the ecological restoration programme alleviated ecological degradation over the period 1998-2005. However, it was not successful enough in terms of preservation and utilization of environmental resources to enhance sustainability, by using emergy measures of carrying capacity (Dang and Liu 2012). In this study, the simulated results indicate that even if all pixels with gradients [15°decrease to the gradient of 15°, all sparse forestlands become mature forestlands, all lower coverage grasslands become higher coverage grasslands, and all barren lands undergoes forestation, then the soil erosion problems in the study area still cannot be completely solved.…”

Due to fragmentized terrain and physiognomy of typical loess landform, long-term anthropogenic influences, and inherent vulnerability, soil erosion is a serious problem in the Loess Plateau of China. There is a critical need to assess soil erosion and spatial distribution for achieving sustainable land use and comprehensive soil conservation management. Taking the Yangou watershed as a case and using the Landsat Thematic Mapper image (land use map), Digital Elevation Model (DEM), soil maps, and precipitation data, this study integrated the revised universal soil loss equation (RUSLE) with GIS technology to estimate soil loss and its spatial distribution. The benefits of soil conservation of land use types were analyzed and the measures for future soil conservation planning were discussed. The results show that silt-covered land and terrace have high benefits of soil conservation, indicating that building check dam, producing silt-covered land for farming, and converting sloped farmland to terrace are effective ways to control soil erosion in the Yangou watershed. Furthermore, increasing vegetation coverage on lower coverage grassland, especially on the slopes with gradients [25°, and eliminating human disturbance in barren areas are feasible and effective measures for soil conservation planning. This study reveals that the integrated RUSLE-GIS model can evaluate and map soil erosion quantitatively and spatially at watershed scale in the Loess Plateau of China. The findings suggest strategies for coping with future soil conservation planning and provide valuable references for future assessments both in the Loess Plateau of China and elsewhere.

“…They are contingent on technology, preferences and the structure of production and consumption. They are also contingent on the ever-changing state of interactions between the physical and biotic environment [12,13]. The study aims to analyze sport and recreational tourism landscape components (carrying capacity of all four zones in Fruška Gora National Park), on the basis of the opinion of the local population.…”

Negative effects of tourism development in a destination are usually the consequence of the high concentration of tourists, accommodation facilities and the activities that are practiced in a relatively restricted area. One of the most important measures to protect the areas is to calculate the maximum number of tourists that can simultaneously reside in a region, i.e. the determination of the carrying capacity. This paper outlines a method for determining carrying capacity based on zoning of environmental resources and zoning within a region. The paper argues for a return to the idea of identifying maximum appropriate number of users. The main hypothesis of the paper is based on the statement that the development of tourism in Fruška Gora (Mountain) National Park in Northern Serbia must be in accordance with the basic principles of sustainability, including the determination of carrying capacity. The main research goal was to show the opinion of local residents about the uncontrolled development of tourism, and to determine the carrying capacity in four sports and recreational zones of the mountain. The carrying capacity of the area is calculated by Lavery and Stanev formulas.

“…The significant nexus between ecological and economic societies can be portrayed and explicitly highlighted by quantitative emergy analysis so that essential policy suggestions can be raised. Emergy-based evaluation has been widely applied to assess resource consumption, economic growth and human welfare in different regions (Dang and Liu, 2012;Dong et al, 2014b;Hossaini and Hewage, 2013;Lei and Zhou, 2012;Liu et al, 2014aLiu et al, ,b, 2013Liu et al, , 2012aLou and Ulgiati, 2013;Mellino et al, 2014;Su and Fath, 2012;Su et al, 2013b;Zhu et al, 2012).…”
