The site suitability for construction of water conservation structures is an important step towards groundwater conservation in arid and semi-arid regions. Water is the most crucial for maintaining an environment and ecosystem which is helpful to sustaining all forms of the life. The increasing water scarcity day to day has been one of the common problems over a period of time. On top of it, when the area is a part of rain shadow zone like Ahmednagar district, water conservation activities are become more important. The present study aims to identify the suitable zones for water conservation activity. Multi- criteria evaluation is carried out using Geographic Information System (GIS) techniques to help the choice makers in defining suitable site for construction of water conservation structures. Different layers which were considered for multi-criteria evaluation: slope, land use land cover, soil texture, lithology, soil depth, soil erosion, wells, lineaments and drainage network. Analytical Hierarchy Processes (AHP) is used for weighted sum to find suitable sites for implementation of water conservation activity using selected criterions. The site suitability map was classified into four classes: highly suitable, moderately suitable, less suitable and not suitable with area of 19.19%, 26%, 49.03% and 5.78, respectively. This map will help for selection of suitable sites for construction of Mati Nala Bund (MNB), Check Dam, Cement Nala Bund (CNB) and Continuous Contour Trenches (CCT) for conservation of groundwater resource in the region.

Land suitability study for agriculture is a very important technique in deciding future agricultural cropping pattern, planning and activities. Land suitability analysis is an assessment of an area to determine how proper or appropriate it is for a particular use of the land (such as growing a crop variety) in a particular location. Land suitability tools have been extensively applied to identify better management practices in agricultural areas. Soil and landscape properties are essential in this type of evaluation, fact that makes especially interesting, is the coupling of this type of model with Geographic Information Systems (GIS) and Remote sensing (RS). The integration of RS-GIS, Fuzzy-logic and application of Multi-Criteria Evaluation using Analytical Hierarchy Process (AHP) could provide a superior database and guide map for decision makers considering crop land substitution in order to achieve better agricultural production. A review was carried out for different multicriteria analysis to develop land suitability maps. Fuzzy-logic integrated with Multi-Criteria Evaluation in GIS environment found most suitable for agricultural crops.

Citropsis articulata (Spreng.) is a potent medicinal plant that is increasingly threatened by unsustainable harvesting and habitat destruction due to deforestation. This calls for enhancement of ex-situ conservation of C. articulata through offsite production. However, the success of offsite production of this species heavily rests on precisely assessing the suitability of the land for its production. In this study, an integrated GIS based multi-criteria evaluation approach was used to depict suitable areas for production of C. articulata based on key factors of; climate, soil and topography. Results revealed that only 13.04% (31495.77 km2) of Uganda’s land is very suitable to support natural production of C. articulata and is mainly situated in the western and central regions. Findings further revealed that 76.4% (24062.77 km2) of very suitable land area is situated outside protected areas, thus implying availability of potential sites for ex-situ and commercial production of C. articulata in the country. Findings also indicated that C. articulata has potential of thriving in well drained, moderately acidic soils and pleasantly warm regions endowed with moderately high precipitation and humidity. Since current stocks of C. articulata are mainly restricted to protected areas, cultivating this species will provide alternative sources of the plant harvest. This will help to relieve current pressures on the wild populations of C. articulata, thus providing a safety backup to the current in-situ conservation efforts.

The research goal is to evaluate land suitability for geo-tourism focuses on geology and landscape. Most of the Citatah karst area is natural-based industries or mining in particular. The ecological disturbance is an impetus for decision-makers to choose new use of land to deal with the conservation issues. SMCE techniques that apply geographic information systems (GIS) and analytical hierarchy processes. The use of land is formulated based on policy and stakeholder analysis. The research benefit is the possibility to change the area from mining to a geo-tourism area. There are two important results of research in spatial analysis, namely: intensive and extensive tourism areas, and the rest is for protective or no suitable area of tourism. In conclusion, the land suitability analysis is important for tourism industry development.
