The Mid-eastern Inner Mongolia of China, a typical agro-pastoral transitional zone, has undergone rapid agricultural land use changes including land reclamation and cropland abandonment in past decades due to growing population and food demand, climatic variability, and land use policy such as the "Grain for Green" Project (GFG Project). It is significant to the regional ecology and sustainabil...

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.

Overgrazing is the most important agent which causes accelerated soil erosion and land degradation in arid and semi-arid zones of Iran. Appropriate planning and land use in these areas based on land suitability evaluation provide a suitable base for conserving the land and controling desertification. Land evaluation identifies possible alternatives in land use which will more effectively meet n...

Land-use planners oftenmake complex decisions within a short period of time when they must take into account sustainable development and economic competitiveness. A set of land-use suitability maps would be very useful in this respect. Ideally, these maps should incorporatecomplexcriteria integrating several stakeholders’ points of view. To illustrate the feasibility of this approach, a land su...

unplanned urban development imposes significant pressure on land resources and land use structures and brings about many negative socio-economic and environmental consequences. therefore, comprehensive studies should be applied to support urban land use management in the world and especially in developing countries. in iran, like many other developing countries, urban development is fast and of...

The efficient use of water resources, soil, and climate parameters as the main pillars of plant sustainable production requires land suitability evaluation for each crop and area. This research was conducted to evaluate land suitability for walnut cultivation in Iran using geographic information system (GIS). For this purpose, the climate data obtained from 375 synoptic stations of Iran, the ge...
