Until 2000, there were no studies about the total economic value of lake Singkarak resource.

In order to quantify the value above, he used some approaches that based on the concept of individual willingness to pay, by using the framework of the total economic value. The study shows that total economic value of natural resources and environmental of Singkarak lake is Rp. 174.950 billion per year. It consists of (a) the economic value of fishery Rp. 7,328 billion, (b) the economic value of irrigation Rp. 0, 775 billion, (c) the economic value of recreation Rp. 4,176 billion, (d) the economic value of domestic use Rp. 7,718 billion, and (e) the the economic value of electricity power Rp. 154,992 billion. These findings are usefull for the government as the policy maker to manage the development of lake Singkarak’s natural resources and its environmental efectively and sustainability.
