Synthesized technical and socio-economic efficient evaluation of water quality improving devices and technologies: an example of the lake Kasumigaura Basin

Abstract

In this study, we analyze an optimal policy and evaluate new devices and technologies to improve the water quality of Lake Kasumigaura, considering both - the total ecological system in and around the lake and the socio-economic situational changes over a certain period of time. The optimal policies are derived so as to maximize the objective function (GRP) subject to the structural equations, which describe both the ecosystem and socio-economic system.
