Review of Valuation Methods for Mangrove Ecosystem Services.

Ecological Indicators (Impact Factor: 3.44). 12/2012; 23(23):431-446. DOI: 10.1016/j.ecolind.2012.04.022


The goods and services provided by natural ecosystems contribute to human well being, both directly and indirectly. The ability to calculate the economic value of the ecosystem goods and services is increasingly recognized as a necessary condition for integrated environmental decision-making, sustainable business practice, and land-use planning at multiple geographic scales and socio-political levels. We present a
comprehensive overview and summary of studies undertaken to investigate the ecosystem services of
mangrove forests. We address the variety of different methods applied for different ecosystem services
evaluation of mangrove forests, as well as the methods and techniques employed for data analyses, and
further to discuss their potential and limitations.

    ABSTRACT: Mangrove habitats are important carbon(C) reserve sites. However, the overgrowth or overexpansion of mangroves may increase the risk of flooding, thus affecting human wellbeing. To decrease the flood risks, partial mangrove removal has been proposed as a managerial action, which would decrease the C stocks. Using the Danshuei River as a case study, the objective of this study was to determine the optimal removal area to allow the mangroves to meet the demands of reducing the loss of mangrove C stocks and adequately controlling the flood risks. Our results show that the ratios of the effective reduction in flood level (benefit) and the loss of mangrove C stocks (cost) were only higher under the condition of the removal of aboveground structures of mangrove trees than the ratios under the condition of the removal of both above- and belowground structures. The highest ratio of the effective reduction in flood level and the loss of mangrove C stocks occurred under the condition of removal of 20% of aboveground structures of mangrove trees, indicating the optimal removal area for mangrove management in the Danshuei River. This study provides a case study exhibiting the tradeoffs between ecosystem services in mangrove management.

    • "con tributes to protect local communities from natural disasters . This crucial function of mangrove species should be noticed and enhanced by the policy makers especially in the context of climate change . Various valuation methods for ecosystem services provided by the mangroves have been reviewed and discussed in previous studies ( Lal , 2003 ; Vo et al . , 2012 ) . In this study , contingent valuation method ( CVM ) was applied to value the willingness to pay ( WTP ) of restoration of mangrove forest in Thi Nai lagoon . Based on a hypo thetical market , CVM ( Mitchell and Carson , 1989 ) is a survey - based approach , in which , an individual independently state his or her willingness to pay ("

    ABSTRACT: Mangroves in Thi Nai lagoon have typically provided different values for local communities. This study examines the factors influencing on the willingness to pay (WTP) of respondents for mangrove restoration in Thi Nai lagoon, Quy Nhon city, Binh Dinh province, Vietnam. A contingent valuation survey was employed in order to estimate the willingness to pay for mangrove restoration under the context of climate change. Findings showed that local awareness of the importance of the values given by mangroves was popularized among local communities. Noticeably, regression results indicated that respondents who consider the future climate scenario is severe are willing to pay more for mangrove restoration. In addition, households with permanent housing condition or whose livelihoods have greater dependence on the mangroves are willing to have higher contribution for mangrove restoration. The study suggests that local awareness of the mangroves importance, as well as the necessity of mangrove protection and restoration, should be publicly enhanced in the context of climate change and urbanization. Since mangroves can make significant contribution to reduce climate change impacts, the urban expansion plan of Quy Nhon city should be carefully considered as it can influence the existence of the mangroves in the long term.

    • "Mangroves are ecosystems at the boundary of land and sea, composed by typical halophytes flowering trees and shrubs, occurring in tropical and subtropical intertidal regions. They are sources of valuable ecological and economic resource, being important nursery grounds and breeding sites for birds, fishes, invertebrates, reptiles and mammals; a renewable source of timber; accumulation sites for sediment, contaminants, carbon and nutrients; and offer protection against coastal erosion (Vo et al. 2012). The main threats to the mangrove forests all around the world are related to the anthropogenic activities such as; overexploitation for timber, fishing and harvesting of shellfishes; and habitat loss caused by aquaculture, altered hydrology, sea-level rise and coastal development.

    ABSTRACT: Ucides cordatus (Linnaeus, 1763), found in mangroves along the Brazilian coast, is an artisanal fishery resource harvested as a source of income and for subsistence. A 12 month study of U. cordatus was conducted in a mangrove area of the southeastern Brazilian coast to estimate the growth, longevity, sex ratio and population density of the crabs. A total of 1024 crabs (505 males and 519 females) were sampled. Carapace width (CW) ranged from 49 to 90 mm (mean +/- SD: 71.2 mm +/- 6.0) for males and from 52 to 83 mm (69.3 mm +/- 4.9) for females. Males dominated the largest CW classes. The asymptotic size (CW infinity) and the asymptotic weight (WW infinity) were estimated as 93.4 mm and 305.5 g, respectively, for males and as 87.1 mm and 221.5 g, respectively, for females. The estimated maximum longevities were 17.6 years for males and 15.7 years for females. The males (k = 0.17, Phi = 1.171) and females (k = 0.19, Phi = 1.159) showed similar growth rates. The mean density was 0.41 +/- 0.19 burrows m(-2). Of this total mean density, 85.8% corresponded to the immediate harvesting potential and 14.2% to the future harvesting potential. Given that U. cordatus is a long-lived species that grows slowly, an appropriate strategy for the management is crucial to ensure the sustainable exploitation of this resource.
