The residential lakeshore access allocation problem: Minimizing barrier effects on shoreline habitat buffers

Residential lakeshore development is causing increasing pressure on the lacustrine environment. Traditional landscaping patterns produce lakes ringed with lawns at the expense of the naturally occurring shoreline habitat. In this work, we present a mathematical model to select path locations to minimize impacts on the lakeshore environment, while providing convenient access to the landowners.     

Spatial based compromise programming for multiple criteria decision making in land use planning

Today, competing land use is continuing to occur in many developed regions. In the Agricultural Development Zone of Western Sydney Region, which is characterised by complex landscape patterns, land use competition is widespread. From a land use planning perspective, identification of suitable locations for a given type of land use is necessary for decision makers to formulate land use alternatives in different locations, based on existing land potential and constraints. For such a region, use of a simple method that implements a categorical system and considers only inherent land characteristics in the analysis is often inadequate to arrive at an optimal spatial decision. The primary aim of this paper is to develop spatial modelling procedures for agricultural land suitability analysis using compromise programming (CoPr) and fuzzy set approach within a geographical information systems (GIS) environment. Five main sets of spatial data for use as decision criteria were developed by using fuzzy set methodology: a land suitability index (LSI) for maximising the land productivity objective; an erosion tolerance index (ETI) for minimising the erosion risk objective; a runoff curve number (CN) for maximising the water discharge regulation objective; an accessibility (RP) measure for maximising the land accessibility objective; and the proximity to water body (WP) for minimising the water pollution objective. An L _p -metric was used in the analysis utilising different strategies with representative indices ranging from a situation where full tradeoff among criteria occurs to a noncompensatory condition. Different weighting combinations were also applied, and decision analysis was carried out by using values ranging from 0 to 1.0, where 1.0 is considered as an ideal point. The CoPr model demonstrated in this paper yielded a promising result, as several different techniques of sensitivity analysis show reasonably good results. Likewise, an overlay of that result with the present land use/land cover indicates a good corresponding spatial matching between existing land use (orchard and cultivated land), and the cells (land parcels) classified as the best in CoPr. The results are amenable to various map display techniques, either using continuous values or by defining different cut off points in the data space within a raster GIS environment.     

Environmental and socio-economic evaluation of four different sites for a domestic airport

During World War II, a military airport was built inside the city of Reykjavik. This airport then became the centre of domestic aviation for the whole country. Today, 50 years later, the airport tract has become valuable for urban development. The city government therefore wants the airport relocated. Four different sites have been considered. The first alternative is to maintain the airport in the same place. A second alternative is based on reclaiming land alongside the present airport. A third possible site is in a rugged lava field south of Reykjavik, and the fourth alternative is to move the domestic traffic to Keflavik International Airport about 60 km away. The relocation has become a hot issue in the country. The people living in the countryside want to keep the airport in the same place. On the other hand, people living in Reykjavik see the airport land as valuable potential for urban development close to the city centre. To approach this debate in an orderly fashion, the four sites have been studied from an environmental and socio-economic point of view. The four alternatives are classified by four different categories: (1) economy and capital investment, (2) social impacts, (3) direct environmental consequences, and (4) public safety. Firstly, the last three categories were evaluated and weighted, and all four alternatives graded according to their environmental quality. Secondly, using the results of a separate cost-effectiveness study, a Pareto optimality solution is suggested. Finally, sensitivity analysis was carried out to investigate how the “environmental” factors through their variation can influence the final selection.
