Abstract Despite the significant role of wetlands in maintaining a healthy ecosystem and providing various ecosystem services, they are under threat due to human activities and agriculture use. The fact that the economic value of ecosystem services is not considered in hydro-economic models and integrated water resources management is a key issue that affects the ecosystem and its degradation. the economic value of ecosystem services provides a quantitative and important basis for the reasonable management of water resources. Given that supplying the agriculture and environmental demands conflict with each other, achieving a balance between these goals is very important. So, in this study, a simulation-optimization (WEAP-PSO) approach is employed for optimal planning at the basin and designing environmental flow based on wetland ecosystem services. The objective function of the problem is considered to be the total economic value of the river, which includes the economic value of the agricultural sector and the economic value of the wetland ecosystem services. The decision variables of the problem are considered as, the cultivation area of agricultural units and environmental flow of Kani Barazan wetland. The results show that considering these two objectives together, in addition to sustainable development, causes the highest economic efficiency in the basin.

Total Economic Value

In the last two decades different methodologies for assessing the economic implications of protected areas have been developed within the framework of "Total Economic Value", taking into account not only goods and services that have a price and a market but also those not priced or marketed. The present paper, by using a number of recognized methodologies applied by environmental economists around the world, estimates the economic value of ecosystem services of Piatra Craiului National Park, in one of the first attempts to frame ecosystem services valuation in Romania. The approach and results include a benefit distribution analysis, for both the economic sectors and the groups of beneficiaries. Even if the data are not comprehensive and depend on several assumptions, the paper provides very important practical and policy-relevant information on the economic value of Piatra Craiului National Park, in an attempt to stimulate increasing of the budgetary allocation and economic policy priority for protected areas in Romania.

Abstract. This paper reviews the changing relation between human beings and water since the Industrial Revolution, a period that has been called the Anthropocene because of the unprecedented scale at which humans have altered the planet during this time. We show how the rapidly changing world urges us to continuously improve our understanding of the complex interactions between humans and the water system. The paper starts by demonstrating that hydrology and the science of managing water resources have played key roles in human and economic development throughout history; yet these roles have often been marginalised or obscured. Knowledge of hydrology and water resources engineering and management helped to transform the landscape, and thus also the very hydrology within catchments itself. It is only fairly recent that water experts have become conscious of such mechanisms, exemplified by several concepts that try to incorporate them – integrated water resources management, eco-hydrology, socio-hydrology. We have reached a stage at which a more systemic understanding of scale interdependencies can inform the sustainable governance of water systems, using new concepts like precipitation sheds, virtual water transfers, water footprints, and water value flow.

Direct and indirect use of values and non-use values from forest ecosystem services perform an invaluable set of functions that cater to the needs of both living and non-living things. The values include market services obtained from timber and non-timber forest products, and non-market services (recreation, watershed protection and conservation value) were identified as components of the Total Economic Value (TEV). However, it is difficult to assign a monetary value to all goods and services provided by the forest. Failure to conserve the national park will result in the degradation of the forest and a reduction in the contribution of the forest ecosystem services to the community. Based on the result of this study, the TEV value of forest ecosystem services was estimated at RM 13 billion, and the estimation provides policy-relevant information for forest management and conservation purposes in Malaysia.

Ecosystem services in oil palm plantations owned by smallholders in four villages in the Riau Province, Indonesia were identified and valued. Nine provisioning, three regulating and maintenance, one cultural ecosystem service, and a single ecosystem dis-service, were identified from interviews with 62 farming households. Direct and indirect market valuation methods were used to estimate the total economic value (TEV) of these services, which averaged USD 6520 ha−1 year−1 (range = USD 2970–7729 ha−1 year−1). The values of provisioning services were USD 4331 ha−1 year−1 (range = USD 2263–5489 ha−1 year−1), regulating and maintenance services were valued at USD 1880 ha−1 year−1 (range of USD 707–3110 ha−1 year−1), and cultural services were USD 309 ha−1 year−1. We conclude that identifying and valuing ecosystem services offers an opportunity to improve the environmental and economic sustainability of smallholders in oil palm landscapes in Indonesia.

The benefit of ecosystem services are the completeness of the outputs resulting from biological, physical, chemical, and socio-cultural processes in the forest that are useful for human life and environment. The object of research is to know how much the economic value of fauna in ecosystem services which has been utilized by the community buffer village and the dependence on Baluran National Park (BNP). Method of research by quantitative and qualitative analysis. Data collected are typological conditions of BNP community buffer village, human resources who used the services of BNP ecosystem services, identity of community who used ecosystem services, types of ecosystem services used by community, harvest season, location of ecosystem services, community income that uses ecosystem and dependence on BNP ecosystem services. The result of research are economic value of the services of fauna that ecosystem components of BNP that have been used by buffer community village and dependence on BNP have form of forest honey (Rp. 1,073,332,000), kroto (Rp. 784,665,000), and snails (Rp. 648,080). Total economic value of fauna that ecosystem component of BNP is Rp. 2,506,077,000,- per year

Mangrove ecosystems become an important ecosystem for the community of Mandah district, this is because the community uses the mangrove ecosystem as a producer of mangrove wood, as well as a place to catch fish, shrimp, and crabs. Therefore, it is important to maintain the sustainability of mangrove ecosystems in multiple ways; one option is by providing an economic report regarding the mangrove ecosystem. The purpose of this study is to estimate the economic value of mangrove ecosystems. This research was conducted in Mandah District using the survey method. Data analysis using economic valuation by calculating the total economic value of mangrove ecosystem services, comprising: supporting services, provisioning services, regulating services, and cultural services. The results showed that the total economic value of mangrove ecosystem services which has an area of 31,007 Ha amounting to IDR 6,100,130,675,685/year or IDR 196,733,985/Ha/year consisting of the value of supporting services amounting to IDR 2,843,521,034,280/year, the value of provisioning services IDR 120,274,922,887/year, the cost of regulatory services is IDR 3,132,894,718,518/year, and the value of cultural services is IDR 3,440,000,000/year. The high economic value of regulating and supporting services indicates that the mangrove ecosystem has a high value of environmental services, so it needs to be preserved and the sustainability of the mangrove ecosystem to remain of high economic value.
