“…The loss of mangrove forest cover also reduces forest biomass, emitting carbon into the atmosphere (Eid and Shaltout 2016;Perez et al 2018). However, the extent of mangrove ecosystems, which are critical for providing local environmental services as well as global climate change mitigation, is declining at an alarming rate every year (Barbier 2012;Wiwatthanapornchai et al 2014).…”

Abstract. Harefa MS, Nasution Z, Mulya MB, Maksum A. 2021. Mangrove species diversity and carbon stock in silvofishery ponds in Deli Serdang District, North Sumatra, Indonesia. Biodiversitas 23: 655-662. Mangrove-based silvofishery ponds are promoted as a win-win solution for biodiversity conservation, climate change mitigation as well as income generation for coastal communities. This study aimed to analyze the species diversity and carbon stock of mangrove vegetation in silvofishery ponds in Tanjung Rejo Village, Percut Seituan Sub-district, Deli Serdang District, North Sumatra, Indonesia. Data of the mangrove species were obtained using vegetation analysis, and the potential carbon stock was estimated based on allometric equations of both above- and below-ground tree biomass. For this purpose, plot samples from 22 silvofishery ponds were taken by establishing 5 aligned circular plots, each with a radius of 5.64 m, perpendicular to the coastline and with a distance of 15 meters between their perimeters. The results show that the mangrove species with the highest Importance Value Index (IVI) was Rhizophora apiculata (122.05%), followed by Excoecaria agallocha (42.29%) and Avicennia marina (36.84%), and the lowest IVI was Sonneratia caseolaris (1.48%). Higher IVI values indicate a larger carbon deposit from mangrove vegetation in silvofishery ponds. Our results indicate that mangrove area coverage of 44-80% per hectare in silvofishery ponds can deposit 40-50 tonnes of carbon per hectare and have greater potential carbon stock compared to coverage below 40%. The mangrove management activities with the sylvofishery scheme have a good impact on the community's economy and also maintain the existence of mangroves as carbon storage.

“…Meanwhile, the loss of mangrove forests will reduce forest biomass and release carbon into the atmosphere (Eid and Shaltout 2016;Perez et al 2018). The mangrove ecosystem which is decreasing in size every year is quite worrying, because the mangrove ecosystem is important in providing local environmental services, as well as mitigating global climate change (Barbier 2012;Wiwatthanapornchai et al 2014).…”

Abstract. Akhbar, Naharuddin, Arianingsih I, Misrah, Akhbar RK. 2022. Spatial model of forest area designation and function based on multi-criteria in dry land and mangrove forest ecosystems, Central Sulawesi, Indonesia. Biodiversitas 23: 3620-3630. Along with the dynamics of rapid social change and the need for land for economic development, land and climate parameters on changes in the designation and function of forest areas, it is time to integrate with socio-economic parameters and government policies while still paying attention to the condition of existing forest vegetation cover. This study aimed to develop a spatial analysis model of changes in the designation and function of forest areas based on multi-criteria in dry land and mangrove forest ecosystems. The research used a descriptive-spatial method with a multi-criteria-based decision-making technique for changes in the designation and function of forest areas. The data analysis utilizes Geographic Information System. The motivation for the proposed forest area change is the target to be achieved in the multi-criteria decision analysis. This research resulted in a spatial analysis approach that integrates scoring techniques and multi-criteria-based decision-making techniques. In Locus BL_010, a change in the function of forest area can be generated, while in Locus TL_003 a decision is made to change the allocation and function of forest area. The achievement of multi-criteria-based spatial analysis on changes in the designation and function of forest areas is quite flexible in decision making because each proposed motivational target will be achieved if it is in accordance with the established criteria and field facts.

“…Four of these 11 papers studied CES in Africa (Nigeria and Kenya), 3, including both Khaleel studies, were done in the Indian Subcontinent (Kerala and Bangladesh), 3 in Asia (Philippines, Thailand, and Asia in General), and 1 in the Caribbean (Martinique). Only three studies (Padilla, 2008;Wiwatthanapornchai et al, 2014;Failler et al, 2015) defined the CES they valued, the latter two used the Millennium Ecosystem Assessment (2005) definitions, while Failler et al (2015) used definitions generated by surveying the local stakeholders. The remaining studies either did not provide explicit definitions of the cultural service being valued or referred the reader to previous studies.…”

“…Failler et al (2015) used the results of survey data collected in Martinique to define the "bequest" value as "passing on the [fishing] lifestyle to future generations." Wiwatthanapornchai et al (2014) used household survey data from a mangrove ecosystem in Thailand to assess aesthetic and national heritage value. These studies provide a good model from which to start.…”

Mangrove Ecosystem Service Values and Methodological Approaches to Valuation: Where Do We Stand?

Mangroves, seagrass meadows, and salt marshes, collectively termed "Blue Forests," are counted among the most valuable and productive coastal ecosystems on the planet. A recent literature review of the Blue Forest valuation research identified mangroves as the most frequently analyzed of these ecosystems, yet the literature demonstrates several deficits in terms of geographic location of studies, methods used to value the services, and most notably, a lack of valuation for cultural services. To better understand this, we analyzed the studies dealing specifically with mangroves from the original literature review to quantify what has been valued, where, by which methods, and the variation in the published values. We then use this information to synthesize our current level of knowledge on the type and value of services provided by mangroves, discuss data gaps, and address specifically the collection of data relevant to cultural ecosystem services (CES). Our results shed light on two principle issues affecting the mangrove valuation literature: overuse of benefit transfer in valuing mangrove ecosystem services and a lack of attention paid to the CES that mangroves provide. The mangrove valuation literature is not yet robust, lacking estimates of many ecosystem services, including CES, such as spiritual and aesthetic value. Most published studies focus on a small selection of ecosystem services based on the availability of benefit transfer values and the ability to easily measure values with market prices. Thus, many ecosystem services that cannot be valued monetarily, but that are often equally important to local communities, are ignored. Given the wide range of ecosystem services mangroves provide and the variety of valuation methods that need to be collectively employed, we argue that doing valuation studies well requires a multidisciplinary approach, bringing together anthropologists, social scientists, ecologists and economists. Thoughtfully and thoroughly including the local stakeholders in valuation studies and the resultant policy discussions leads to a more holistic understanding of the services mangroves provide, and viable solutions with an increase in local willingness to act in accordance with those solutions.
