Determining the feasibility of a large-scale afforestation program is one approach being investigated by the Government of Canada to increase Canada's potential to sequester carbon from the atmosphere. Large-scale afforestation, however, requires knowledge of where it is suitable to establish and grow trees. Spatial models based on Boolean logic and/or statistical models within a geographic inf...

This paper presents some preliminary results from a research on spatial multi-criteria evaluation of land suitability for intensification or extensification in irrigated cropland at a catchment scale in Australia. The project was conducted using the fuzzy linguistic ordered weighted averaging (FLOWA) approach which integrates AHP and fuzzy linguistic OWA operators in ArcGIS 9.2 environment. Sev...

Crop planting suitability evaluation is important for agricultural production. In this study, a comprehensive evaluation framework which combined geographical information system, remote sensing, global position system and geostatistics with other models was presented to evaluate the tobacco planting suitability on a small scale. Ten indicators from three respects of climate, terrain and soil nu...

land evaluation and its consistency with simulation model’s outputs could assist decision making to develop plants for cultivation. in this study land suitability and potential yield of cumin was determined using cummod and sum of values method by climatic and topographic factors, respectively, as a case study in khorasans provinces. results revealed that despite of the majority of favorable an...

BACKGROUND The land and ecology suitability for producing pollution-free Chinese medicinal materials should be evaluated based on Geographic Information System (GIS). This study aims to determine production regions for pollution-free Achyranthes bidentata in Tianjin as a case to illustrate the workflow based on GIS. METHODS The slopes, land usage, residential areas and roads were selected to ...

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...

In this study, a geospatial model for land use allocation was developed from the view of simulating the biological autonomous adaptability to environment and the infrastructural preference. The model was developed based on multi-agent genetic algorithm. The model was customized to accommodate the constraint set for the study area, namely the resource saving and environmental-friendly. The model...

Newly reclaimed areas cover several patches over different regions of Egypt, which have different specific characteristics related to climate, soils, hydrology, etc... . The mechanical farm, which extends over 10,000 feddans fares from south of Alexandria by 62 Km, could be considered one of the most important reclaimed areas at West of Nubaria affected by degradation due to water logging. The ...
