Abstract
So far, there have been no economic valuation studies to ecological studies that reveal the potential of the Tempe Lake area, so that policy makers have not been able to manage and use the Tempe Lake Area, at the most effective and efficient level, and able to distribute the benefits and costs of conservation fairly. The novelty of this research is trying to do an economic valuation, which is paralleled with an ecological study of the existence of Lake Tempe. This study aims to identify the ecological functions of Lake Tempe that give rise to various economic and non-economic benefits for the community around Lake Tempe, as well as to determine the amount of Total Economic Value (NET) of Lake Tempe. The data were analyzed by adding up the value of direct benefits, value of indirect benefits, value of choice benefits, value of existence benefits and value of inheritance benefits in the Tempe Lake area. This research data was collected through surveys and interviews with stakeholders who have a reciprocal relationship with the Tempe Lake area in Wajo Regency. The results showed that the total economic value obtained for the Tempe Lake area was Rp. 5,742,249,708,120,- per year with the largest contribution coming from the direct benefit value of Rp. 4,571,395,793,250,- per year or 78.7%. The implication of the research is the need for cross-sectoral joint coordination from various levels of government, to encourage the rehabilitation of forest areas around the Walennae and Bila watersheds. Dredging of Lake Tempe is urgently needed to cope with the annual flooding due to overflow of water. In addition, to increase the utilization of Lake Tempe, a more massive synergy between stakeholders is needed, to develop other untapped potential of the Lake Tempe area.Keywords: Valuation; Resource Economics; Ecology
Highlights
Ecological damage necessitates environmental damage to the livelihoods of the surrounding community, this is a very real phenomenon in various areas, both at the rural to urban level
The problem faced by Lake Tempe is that every rain in the upstream area will cause an overflow of water from Lake Tempe which causes flooding in the area around the lake
The total sediment that enters Lake Tempe is 1,069,099 million m3 according to a study by JICA in 2002 and the Bappedalda of Wajo Regency that every year there is silting that ranges from 15-20 cm and tends to increase every year
Summary
Ecological damage necessitates environmental damage to the livelihoods of the surrounding community, this is a very real phenomenon in various areas, both at the rural to urban level. The problem faced by Lake Tempe is that every rain in the upstream area will cause an overflow of water from Lake Tempe which causes flooding in the area around the lake. Sediment deposits from mud washed away by river currents resulted in the lake getting shallower. The total sediment that enters Lake Tempe is 1,069,099 million m3 according to a study by JICA in 2002 and the Bappedalda of Wajo Regency that every year there is silting that ranges from 15-20 cm and tends to increase every year.
