The suitability of the land resources in the watershed for various crops is necessary to choose the right crop and variety suitable for the area. In carrying out this assessment, the specific land requirements of a crop are compared with the characteristics of land resource mapped in the sub- watershed with this objective  investigation was carried to assess land suitability for growing horticultural crops in Kanamadi South sub-watershed of Vijayapura district of Karnataka. The soil survey was conducted using 1:7920 scale, LISS IV satellite imagery.  The soils were shallow to deep with clay loam to clay in texture. The soils were low in nitrogen and organic carbon, low to medium in phosphorus and sulphur, medium to high in potassium. Iron, copper, zinc and manganese were sufficient. Land suitability evaluation revealed that soils were moderately suitable for growing fruits such as guava (73.75% TGA), pomegranate (70.73% TGA), sapota (85.65% TGA). In case of flowers, major part of the study area was marginally suitable for crops such asrose (65.26% TGA) and jasmine (91.72% TGA). Around 11.55 per cent of the area was evaluated as unsuitable for growing fruit crops. The consideration of depth and nutrient status of soil in sub-watershed area is ideal to grow the horticultural crops like fruit crops with soil conservation measures to obtain food sustainability and nutrition level of people living the study area.

Agricultural land use planning should always be guided by a reliable tool to ensure effective decision making in the allocation of land use and activities. The primary aim of this study is to develop a user friendly system on a spatial basis for agricultural land suitability evaluation of four groups of agriculture commodities, including food crops, horticultural crops, perennial (plantation) crops, grazing, and tambak (fish ponds) to guide land use planning. The procedure used is as follows: (i) conducting soil survey based on generated land mapping units; (ii) developing soil database in GIS; and (iii) designing a user friendly system. The data bases of the study were derived from satellite imagery, digital topographic map, soil characteristics at reconnaissance scale, as well as climate data. Land suitability evaluation in this study uses the FAO method. The study produces a spatial based decision support tool called SUFIG-Wilkom that can give decision makers sets of information interactively for land use allocation purposes.This user friendly system is also amenable to various operations in a vector GIS, so that the system may accommodate possible additional assessment of other land use types.

Constructive land suitability evaluation is the premise of effectively disposing land resource. China is in the historical period that urbanization develops fleetly; the demand of construction land grows rapidly; carrying on the research about method of constructive land suitability evaluation presents strong practical significance and broad application prospect. The paper summarizes basic analysis method of constructive land suitability evaluation based on GIS from five basic links which cohere each other, and then introduces the research development of constructive land suitability evaluation from angles of ensuring evaluation factor and factor weight, evaluation factor classification, land classification. Finally, the paper analyses research direction of this work from angles of consummating the evaluation method and using new mathematical method, releasing the related criteria by government department, and the combination between urban extended model, area development strategy, and GIS.

The purpose of this research was to determine thepotential land resource for the forage development. The method used is descriptive method by direct observation. The results showed that the overall physiographic conditions of the area in both sites flat to undulating (0-8% slope). All areas are included in the regional development of farm area (Rantau Panyang and Keude Field) included in the moderately suitable (S2) with 2 (two) sub-class of S2wa,fh,nr; and S2wa, fh, lp, nr, in turn, results Actual land suitability evaluation included in the category of moderately suitable land suitability class (S2) with two sub-classes namely S2wa,fh,lp,nr and S2fh, lp, nr.There is a difference between areas in the Rantau Panyang and Keude Lapang good views from the species and botanical composition of the species that dominate in the location of the Rantau Panyang is Cyperus bifax and Imperata cylindrica in the location of Lapang.

The mechanistic cropping systems model PERFECT was validated for six different soils and used as a tool to evalute land suitability of wheat cropping in the Maranoa, a marginal cropping area of Queensland. Using 100 years of historic climate data from the area, and crop, soil and management parameters, simulations provided an objective insight into the key interactions of the cropping system. Current methods of land suitability evaluation are qualitative and rely on the experience of the land resource surveyor and local precedent. Consequently, where local precedent is lacking, as in marginal areas, current methods are considered less reliable and quantiative data from simulation studies will be useful. Using this process, the significance of key components of the systems (climate, plant available water capacity, soil nitrate and soil loss hazard) were quantified. These quantitative data were used to establish critical values for diagnostic attributes for land suitability evaluation in the Maranoa. The role for this approach as a tool in quantitative land evaluation is discussed.

Land suitability evaluation has an important role in determining the environmental boundaries of sustainable land resource management. The purpose of this study is to evaluate the suitability of land use in rice cultivation in Magelang, Indonesia. Environmental factors such as rainfall, drainage, depth, pH, organic matter content, slopes, and erosion level are used as criteria compared to 5 alternative lands (Sawangan, Mangunsari, Tirtosari, Podosoko, and Kapuhan). The ELECTRE method as one of the multi-criteria decision-making methods chosen to solve the concept ambiguity problem in land suitability assessment. The result shows that the application of this method is quite effective for decision making so that alternatives are obtained that have the highest land use suitability compared to other alternatives for environmentally friendly rice cultivation. Finally, a decision support system with a web-based ELECTRE Method is presented to facilitate decision-makers in obtaining more accurate land suitability information.
