Habitat suitability models for the focal species are used to address the concerns related to the limited availability of data for remote habitats by scrutinizing the relationship between the biodiversity distribution patterns and the natural-anthropogenic characteristics. The current study aimed at modeling habitat suitability for seven focal species including Asian black bear, Persian leopard,...

Introduction: Rangelands constitute almost 52 percent of the country area computed as 164 million ha. The extent of rangelands has been estimated 84 million ha in Iran and they have been classified as good, moderate to poor and poor to very poor ones ranged as almost 10, 42 and 48 percent, respectively. One of the fundamental problems concerning land uses of rangelands is that Rangeland are not...

On a land suitability assessment map that is derived from an overlay of n parent maps, each bearing k land capability categories, how many permutations of land suitability scores can there be when the scores are calculated by the commonly used rating and weighting method? In this paper, we estimate that this number is between k n(n−1) 2 and kn+1!/(kn!kn−1! · · · k!)k−1.

LSP suitability maps support geographic decision making by providing an efficient framework for evaluating multiple attributes, aggregating the evaluation results, and creating a map that graphically represents the overall suitability of locations for a given purpose. In this paper, we consider elementary LSP suitability map criteria for evaluating a distribution of points of interests (POIs) i...

Land evaluation procedure given by FAO for soil site suitability for various land utilization types for rainfed agriculture has been used to assess the land suitability for khasi mandarin orange and pineapple in East Khasi Hills District of Meghalaya. The database on soil and land use/land cover was generated from IRS-P6 remote sensing satellite data, soil survey and laboratory analysis of soil...

Introduction: Deficit of rainfall and consequently, water scarcity is one of the most important problems in arid and semi-arid areas. Water collecting structures have a positive effect on light textured lands due to deposition of clay and organic matter, as well as controlling the floods will enhance the vegetation (Abdollahi et al., 2015). Water Collection in order to store surface water runof...
