In Iran, the development of cultivated areas becomes gradually impossible due to ever-increasing population growth and urban area development. Therefore, it is very important to use the existing cultivated lands more efficiently. Land suitability evaluation makes the sustainable use of the lands feasible. The objective of this study was qualitative, quantitative and economic assessment of land suitability in Talandahst area for rainfed wheat, barley and chickpea. Talandasht plain with a surface area of 4500 ha is located southwest of Kermanshah city.

In this study, by using cellular analyze method according to ecological criteria, the determination of agricultural land suitability of Research and Practice Farm of Ankara University Agrucultural Faculty Farm and Haymana Research Farm of Central Research Institute for Field Crops lands, which are in Ankara province and Haymana district, was aimed. For this aim, by using Geographical Information Systems(GIS) techniques, the data layers such as some soil properties, topography and irrigation was examined for each land criterion to determine the weighted scale.

We describe a model to predict regolith thickness in a 128,000ha study area in the central Mt Lofty Ranges in South Australia. The term regolith encompasses soil (A and B horizons) and highly weathered bedrock (C horizon). The thickness of the regolith has a major control on water holding capacity for plant growth and movement of water through the landscape, and as such is important in hydropedological modelling and in evaluating land suitability, e.g. for forestry and agriculture. Thickness estimates also have direct application in mineral exploration and seismic risk assessment.

Luwu is one of the regencies located on the east coast of South Sulawesi Province, Indonesia which has large brackishwater ponds area, but it has a low productivity of shrimp and fish. Therefore, a study was carried out to know the land characteristics for determining suitability and management of land for tiger prawn (Penaeus monodon) culture in brackishwater ponds to increase the productivity and sustainability. Factors considered in land characteristics are: topography and tidal range, soil quality, water quality and climate.

SUMMARYSite and soil characteristics associated with existing plantings of whitewood (Endospermum medullosum Euphorbiaceae) were characterised across Espiritu Santo Island in Vanuatu. Two hundred, generally small (most commonly around 0.5 ha), plantations dominated by whitewood have been planted across the eastern side of the island. These plantations range up to 20 years in age and provide a guide to the expected growth rates of whitewood in plantation in those areas.

Wind energy is a renewable energy resource that has increased in usage in most countries. Site selection for the establishment of large wind turbines, called wind farms, like any other engineering project, requires basic information and careful planning. This study assessed the possibility of establishing wind farms in Ardabil province in northwestern Iran by using a combination of analytic network process (ANP) and decision making trial and evaluation laboratory (DEMATEL) methods in a geographical information system (GIS) environment.

Sewage sludge (SS) amendment of agricultural soils has recently become an issue of great interest because improvements in wastewater treatment systems have increased production of this type of waste. This practice is known to benefit soil and crops. However, the potential contamination of the environmental matrices has been rarely assessed because suitable models and data regarding the diffuse contamination of SS in agricultural fields are limited.

Protected areas are established to conserve unique features and biodiversity of the nature. Accordingly, wherever has one of the natural, ecological and/or cultural values it should be considered a protected area. Kave-Deh No-hunting Area is located on extremely east of Tehran Province in an area of 94,961 ha. Due to rich and diverse land cover, distinctive wildlife species, and unique monuments the area was selected as a case study to examine the possibility of its promotion to the protected area using Spatial Multi Criteria Evaluation (SMCE) Method.

The purpose of this work was to adapt the MicroLEIS - Land Evaluation Information System developed in Spain to the Brazilian Southeast conditions. Twelve (12) variables were considered, as follows: A - Relief Factor: 1) Slope; B - Soil Factor: 2) Effective depth, 3) Texture, 4) Stoniness, 5) Drainage, 6) Salinity; C - Erosion Factor: 7) Erodibility, 8) Slope, 9) Vegetation density, 10) Rainfall erosivity; D - Bioclimatic Deficiency Factor: 11) Frost, 12) Available water. For each of them, the control parameters were changed, according to conditions of the soils of the State of São Paulo.

Creation of the Land Information System integrated in the Geographical Information System (GIS) is the main objective of this article in assisting local Government for the sustainable management of land resources. Through this study it was made possible to provide a spatial database at communal level, was also carried out the study of soil and land suitability, data on land use, analysis on land use changes and agricultural land urbanization. The geographical space, in which LIS is set, which is also the objective of this study is Shales commune, Elbasani district.

The hyper-arid conditions, low inherent soil fertility, water scarcity, and marginal water quality collectively constrain the local agriculture production in Abu Dhabi, UAE. To achieve this, an integrated suitability assessment was conducted considering soil resources, relief/slope, and water resources and forms the focus of the present study. The soils were classified using Soil Taxonomy (ST).
