Development Suitability Analysis of Frequently Flood Affected Areas in Sri Lanka – a Case Study in Rathnapura Municipal Council Area

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.

The Impact

This paper will examine the impact of PR electoral systems in a divided society. This research will explore the strength and weakness of the current electoral system and institutional design of Sri Lanka and will recommend changes to decrease the risk of minority exclusion in decision making and ethnic violence. The objectives of this research are to examine the character of the merits and demerits of the PR, and to investigate and assess the impacts of the PR in the multi ethnic societies of Sri Lanka. The study is a qualitative case study, and primary and secondary data sources have been employed to gather relevant data. The My Fieldwork was conducted in Sri Lanka, with the intention of gaining a better and more thorough understanding of the current situation. The interviews conducted were as such not structured or semi-structured, due to the interviewees’ varying professional background and institutional affiliation. Accordingly, unstructured interviews, as well as informal conversations and meetings, were conducted throughout Sri Lanka.
