The effectiveness of conservation plans depends on environmental, ecological, and socioeconomic factors. Global change makes conservation decisions even more challenging. Among others, the components of most concern in modern-day conservation assessments are as follows: the magnitude of climate and land-use changes; species dispersal abilities; competition with harmful socioeconomic activities ...
Land degradation by soil erosion and landslides has been recognised as a constraint for sustainable land-use in Eastern Bhutan for a few decades. However, the extreme diversity in agro-ecological zones, the relative inaccessibility of the region, the lack of reliable data and the limited research capacity made it very difficult to develop a relevant land management strategy. To address this iss...
High-Resolution Satellite Imagery Is an Important yet Underutilized Resource in Conservation Biology
Technological advances and increasing availability of high-resolution satellite imagery offer the potential for more accurate land cover classifications and pattern analyses, which could greatly improve the detection and quantification of land cover change for conservation. Such remotely-sensed products, however, are often expensive and difficult to acquire, which prohibits or reduces their use...
objective: the aim of this study is to provide a management plan for the sykan watershed of darre shahr city located in ilam province using gis in land use planning. methods: for land using of sykan watershed of ilam province with about 9 hectares area, map of classes, elevation, percent slope, geographical aspects, soil characteristics, vegetation density and the final map units were combined ...
ecological capability evaluation and landuse planning can determine the best landuses and are important for the proper planning and sustainable development. there are various methods for ecological capability evaluation. in this research have been studied two methods (land use planning method with makhdoom ecological modsels) and (geomorphology method) for ecological capability evaluation in ne...
In a semiarid region of central Iran, effects of parent materials, physiography and landscape position, land use, andmanagement practices on association of organic carbon with secondary (aggregates) particles and aggregate stability canhave important consequences in terms of carbon sequestration and budgeting, deciding on the proper land use strategy andsuitable soil conservation practices. It ...
The paper investigated the application of MODIS data for mapping regional land cover at moderate resolutions (250 and 500 m), for regional conservation purposes. Land cover maps were generated for two major conservation areas (Greater Yellowstone Ecosystem—GYE, USA and the Pará State, Brazil) using MODIS data and decision tree classifications. The MODIS land cover products were evaluated using ...
Development of land resources can contribute to increased economic productivity but can also negatively affect the extent and condition of native vegetation, jeopardize the persistence of native species, reduce water quality, and erode ecosystem services. Spatial planning must therefore balance outcomes for conservation, development, and social goals. One approach to evaluating these trade-offs...
1- INTRODUCTION Soil as one of the most important inputs in agricultural production process plays an important role in the quality of production operation, food security and sustainable development. On the other hand, soil erosion as one of the environmental agriculture issues has been intensified with increasing population and transforming to intensive forms of agriculture in recent years. Mi...
Map-based prioritization systems have become ubiquitous tools for allocating resources for biological conservation. Although the scientific basis for these systems continues to be debated, they have become a significant factor in international conservation. A recent study found that published conservation priorities are associated with over one third of conservation spending by major internatio...
