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.

Cocoa occupies 6 million hectares in humid coastal West Africa where 70% of the world supply is grown, 90% of which is produced on 2 million family farms of 2 hectares or less. Here, at least 16 million people depend on cocoa but earn only $100/person/year from the crop. There is need to optimize the farming system, minimize the environmental impact of technologies, and improve socio-economic d...

North Bandung area covering structural landforms and volcanoes has an active volcano fault, leading to potential of landslide. This study aims create a new scheme LULC zones based on landslide prone area. The zone is analyzed through Fuzzy the following variables: rainfall, drainage distance, density, slope angle, aspect, distance lineament, elevation, curvature, topographic wetness index (TWI)...

Soil genesis, physico-chemical properties and tea yield were investigated along different hillslope positions in the major tea cultivation area of Iran, i.e. Lahijan, Gilan Province. Land suitability was also determined for the tea production in this hilly region. Four different slope positions i.e., summit, shoulder, backslope and toeslope were sampled on three slope aspects following the prof...

The goal of multi-objective land use assessment and allocation (MOLAA) is provision of an optimal allocation of all land uses with maximum suitability. Different techniques of multiple criteria decision making have proven useful as decision support tool for solving a MOLAA problem. SA and MOLA are two different MCDM approaches that can provide solution to a MOLAA problem using different decisio...
