Sustainable wetland management strategies under uncertainties

Wetlands are widely recognized as transitional areas between terrestrial and aquatic systems. They provide multifunctional benefits, most prominently relating to the ecosystem, the economy and to scenic quality. Extensive areas of wetlands have been lost, either as a direct result of redesignation for other uses, especially industrial and recreational, or by qualitative degradation arising from water pollution. Although researchers have been involved in prolonged debate over wetland sustainable use management issues, the uncertain substitutability and irreversibility factors surrounding wetland functions have rarely been addressed. In considering policies for wetland resource management, decision rules and procedures must be adapted to reflect those uncertainties. In this study, the author incorporates the concept of the safe minimum standard of conservation approach to take account of natural and social uncertainties attending public decisions. By this approach, not only is the role of uncertain substitutability and irreversibility prioritized in addressing wetland sustainable use management strategies, but related policy implications may also be considered.
