“…The amount of raw production from the Cenrana river during 2014 was Source: Primary data output after processing, 2020; (Darsam, 2020) This finding is in line with previous research which revealed that if the lake's potential is managed properly, it can bring in large income for the government, one of which is being a provider of drinking water sources for the wider community. For this reason, the sustainability of drinking water sources for many people is quite dependent on the lake's water resources (Abd Ellah, 2020;Alamanos et al, 2019;Dong et al, 2020;Hou et al, 2020;Liu et al, 2021Liu et al, , 2020Wang et al, 2019).…”

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

“…The results of this study showed the necessity to conduct sub-catchment scale hydrological modeling in the LDB. A study applied in a reservoir-regulated basin of Lake Poyang noted that an increase in reservoir storage can be used to offset extreme climate and hydrological events, whereas reservoir capacity distribution and location are of great importance (Dong et al 2020). If simulations are only performed at the watershed scale, risk differences among subcatchments cannot be identi ed.…”

Climate change has greatly impacted hydrological regimes of lakes in sub-trophic and trophic areas. The uncertainties surrounding conventional future hydrological simulation methods with Coupled Model Intercomparison Project phase (CMIP) climate models have long been debated. However, it is crucial to obtain an accurate assessment result to help with better decision-making. In this study, we used the Lake Dianchi Basin (LDB) as a case study to demonstrate the use of a sub-catchment scale integrated model framework to obtain detailed hydrological simulation results and a comprehensive impact assessment of climate change on hydrological regimes. The results showed that 1) For the sub trophic lake basin LDB, its hydrological regimes are signi cantly impacted by climate change. Precipitation change impacted greater than air temperature change. 2) The 19 hydrological indicators showed large variations among the 18 climate scenarios. Precipitation impacted much greater than air temperature, and wet season might be impacted more by climate change. Climate change might impact more on 1/3/7-day minimums/maximums than 30/90-day minimums/maximums. 3) Enormous ecological and socio-economic risk for the LDB were indicated as its hydrologic regime is vulnerable to climate change. Among all six sub-catchments, Sub_06, characterized by a hilly landscape, would be impacted the most by climate change. 4) This study showed that, in regions with complex climatic conditions and topography, it is necessary to simulate hydrological states at the sub-catchment scale and differences of responses of each indicator to climate change should be fully considered.

“…Despite the importance of reservoir regulation in the water cycle, impact studies of reservoirs are primarily limited to the alteration of streamflow (Biemans et al, 2011; Dong et al, 2020; Gudmundsson et al, 2021; Jaramillo & Destouni, 2015; Zhao et al, 2021). Beyond the altered streamflow, reservoir regulation can also interact with other hydrological compartments, such as groundwater, soil, vegetations and their feedbacks, which is of high importance for the quantification and management of regional terrestrial water resources for different sectors (Barthel & Banzhaf, 2016; Condon & Maxwell, 2014; Somers et al, 2016), such as industry and agriculture (Li et al, 2018; Yao et al, 2018).…”

The regional terrestrial water cycle is strongly altered by human activities. Among them, reservoir regulation is a way to spatially and temporally allocate water resources in a basin for multi-purposes. However, it is still not sufficiently understood how reservoir regulation modifies the regional terrestrial-and subsequently, the atmospheric water cycle. To address this question, the representation of reservoir regulation into the terrestrial component of fully coupled regional Earth system models is required. In
