Abstract: Global warming may cause low-lying areas to be inundated because of frequent flooding and rising sea levels. It may further intensify dehydration of semi-arid zones. Such environmental impacts may require planned relocation of a section of population and force others to adapt to these evolving situations. In this article, we discuss a multi-objective optimisation approach for deciding what fraction of a population will be relocated to another location and what fraction of it may be retained for effective adaptation to climate change. We consider various costs, people|s preferences and priorities of planning objectives in a goal programming model and illustrate the concept with the design of a decision support system for interactive analysis of complex multifaceted environmental decisions.

Keywords: adaptation; AHP; analytic hierarchy process; climate change; interactive DSS; decision support systems; goal programming; interface; multi-objective optimisation; planned relocation; sustainable relocation; relocation strategies; global warming; population relocation; environmental decisions; environmental impact.
