Benefit Estimation

This paper identifies and assesses the economic value of the main natural benefits relating to the complex system of wetlands (CSW) belonging to the San Juan River in the Colombian Magdalena Medio. This is a region rich in biodiversity and natural resources, which in the past was hit by violence and the actions of different armed groups. Benefit estimation takes into account diverse monetary valuation techniques, such as market prices for direct wetland uses and the transfer of benefits, for the assessment of indirect use and non-use values. The results reveal that the most important values relate to ecotourism (60.1%) as a possible future use of the CSW, the benefit of preventing flooding (28.4%), and the biodiversity that inhabits the area (6.7%). All three values represent the total economic value of the CSW. This research also finds that the benefits of the ecosystems currently provided by the CSW exceed the opportunity cost, represented by the total conversion of the area to livestock. Lastly, the net present value (NPV) of 25 and 75 years, relating to the benefits of the CSW, exceeds the income from the conversion of land to livestock, revealing profitable investments in conservation and ecotourism projects.

Promoting forest as one of green economy asset in Indonesia become an important agenda in the process of development. Forests have an important role as a source of foreign exchange and also as a form of natural resource wealth. The era of globalization with the accelerated economic growth increases the need for both, the fields of agriculture, infrastructure, land requirements and other sectors. Increased human needs are giving a positive correlation to the increased pressure on forests. Mangrove forests as one of the most productive ecosystems in the world are also experiencing the same threat. The expansion of settlements and ponds in coastal areas lead to degradation of mangrove forests is very high. The economic value of mangrove forests of diverse functions such as shoreline protection, habitat for aquatic organisms, carbon storage, and a variety of other functions has not been a lot of concern to the public and policy makers. This study aimed to quantify the economic value of mangrove forests in Untung Jawa Island, Thousand Islands as an effort to support the government's program to realize the green economy in the forestry sector. Method of economic calculation mangrove forests in this research is to calculate the Total Economic Value / Total Economic Valuation (TEV), which consists of direct use values (Direct Use Value) and indirect use values (Indirect Use Value). The results showed that the direct use value of mangrove forests in Untung Jawa Island is Rp. 395,126,912 which includes the value of timber, fruit value, and the value of the fishery, while the indirect use value is Rp. 7,500,600,000 calculated from the value of coastal protection, the value of foraging, conservation value, educational value, and recreational value. The total economic value (total economic value) of mangrove forests in Untung Jawa Island reached Rp. 7,895,726,912Keywords : mangrove, green economy, total economic valuation

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.

Cibodas Botanical Garden (CBG) is believed to have high environmental value for its function as conservation area and beautiful scenery. However, prior to this research, there is lack of economic valuation to determine the total value of CBG, including its environment. The local government, on the other hand, needs such environmental economic valuation to execute better decisions related to the CBG. This study aims at providing the mostly-needed economic valuation through the application of Travel Cost Method. The Travel Cost Method (TCM) is a method to calculate the economic value of products or services that do not own market value. This method utilises total cost of consumers who travel to certain places, preferably tourist destinations. The cost spent by consumers are considered as their willingness to pay (WTP) for the visited destination(s). In this study, TCM is used by preparing questionnaires for Cibodas visitors, analysing the results of the questionnaires, calculating the total economic value (TEV) of Cibodas, determining the consumer surplus, and proposing environmental programs at CBG. At the end, it was calculated that the TEV of Cibodas Botanical Garden is IDR113,072,532,700 with average WTP of the visitors IDR202,484 per visitor and the consumer surplus of IDR32,344 per visitor. Also, this study reveals that solid waste management improvement at CBG can be funded by potential income from the consumer surplus.

Wetlands are the most productive ecosystem and provide wide arrays of wetland ecosystems (goods and services) to the local communities in particular and global communities in general. However, management of the wetland often does not remain priority and recognized as the unproductive waste land mainly due to poor realization of the economic value of the wetlands. Taking this into account, the study estimated the total economic value of the Jagadishpur Reservoir taking into account direct, indirect, and nonuse value. The study prioritized six major values of the reservoir which include wetland goods consumption, tourism, irrigation, carbon sequestration, biodiversity conservation, and conservation for future use (existence and option value). The study used market and nonmarket based valuation techniques to estimate total economic value of the reservoir. Household survey, focus group discussions, and interaction with the tourism entrepreneurs and district stakeholders were carried out to collect information. The study estimated the total annual economic value of the reservoir as NRs 94.5 million, where option/existence value remains main contributor followed by direct use value such as wetland goods and tourism and indirect use value, for example, carbon sequestration, biodiversity conservation, and irrigation. The study reveals that the local communities gave high importance to the future use value and are willing to make investment for conservation and restoration of reservoir given its conservation significance.

Abstract Enzyme activity plays an important role in the functioning of aquatic ecosystems. It is sensitive to changes in environmental conditions such as pH, temperature, and nutrient concentration. The objective of this work was to determine the acid phosphatase activity (AcPA) in the Almendares and San Juan rivers (western Cuba) and its relationship with physicochemical and microbiological indicators. For this purpose, AcPA, temperature, pH, total dissolved solids, electrical conductivity, dissolved oxygen, concentration of nitrates, nitrites, ammonium, phosphates, total heterotrophs, enterococci, Escherichia coli, thermotolerant coliforms, chlorophyll a and chemical oxygen demand (COD) were determined at three sampling stations on the Almendares River and at three sampling stations on the San Juan River. In addition, the nutrient pollution index (NPI) and the N:P ratio were calculated. In both ecosystems, spatio-temporal variability was observed in the enzymatic activity. In the Almendares River (polluted ecosystem), AcPA was positively correlated with nitrate concentration and COD. While in the San Juan River (slightly contaminated ecosystem) the AcPA correlated negatively with the pH and NPI and positively with the concentrations of total heterotrophs, Escherichia coli, chlorophyll a and the N:P ratio. These results show the impact of anthropogenic pollution on AcPA in freshwater ecosystems with a tropical climate.
