“…Indonesia has the largest mangrove ecosystem in the world, consisting of 27% (16.9 million ha) of the total world mangrove forest, and is a center of distribution of biodiversity of mangrove species and ecosystem (Spalding et al 2010), yet it undergoes rapid and dramatic destruction (Setyawan et al 2003). Mangroves are invaluable treasure for Indonesian biodiversity with immense ecological and economic significances (Hema and Devi 2015). Mangrove ecosystem has also high economic value both directly and indirectly as this ecosystem is one of the sources of income that is very useful for the community and the country.…”

Abstract. Kristiningrum R, Lahjie AM, Masjaya, Yusuf S, Ruslim Y. 2019. Species diversity, stand productivity, aboveground biomass, and economic value of mangrove ecosystem in Mentawir Village, East Kalimantan, Indonesia. Biodiversitas 20: 2848-2857. Mangrove forest is one of the important ecosystems. It provides a variety of benefits both ecologically and economically. There are many biodiversity values of mangrove ecosystems that it can be evaluated economically. This study aims to: (i) identify the species diversity of mangrove forest; (ii) analyze the mangrove productivity and aboveground biomass; (iii) analyze the ecosystem value of mangrove forest in Mentawir Village, Penajam Paser District, East Kalimantan Province. The research used systematic random sampling method by establishing two plots with extent of one hectare for each plot in which each plot was divided into 20m x 20m subplots. The volume and mean annual increment (MAI), as well as current annual increment (CAI), were calculated. Economic value of mangrove ecosystem was calculated using Contingent Valuation Method (CVM) to reveal the total margin between Willingness to Pay (WTP) of wood produced by mangrove forest and Willingness to Accept (WTA) of fisheries catches. The results showed that there were 12 species of mangroves in the studied areas in which Rhizophora apiculata was the dominant species. Total aboveground biomass in Plot I and Plot II were respectively 127.46 tons ha-1 (62.61 tons C ha-1) and 79.26 (38.85 tons C ha-1) and dominated by Rhizophoraceace family with 76.80%, while 23.22% of the biomass was contributed by other mangrove families. The mangrove forest had a maximum average volume increment at 48 years and 42 years with MAI of 2.97 ha-1yr-1and 2.12 m3 ha-1yr-1 at Plot I and Plot II, respectively, with the total volume reached 127.5 m3 ha-1 and 79.60 m3 ha-1. The calculation of total margin between WTP and WTA indicated that in economic value of mangrove ecosystem in Mentawir Village with an extent of 2,300 ha was between IDR 207,000,000 yr-1 and IDR 345,000,000 yr-1. Our findings suggest that a good mangrove ecosystem will result in high economic value and biodiversity values cannot be separated from economic benefits in order to protect its sustainability.

“…Most of the earlier studies were focussing on specific ecosystems like forests, wetlands, mangroves and similar ecosystems with limited ones on agroecosystems (Marothia, 2001;Das and Cr´epin, 2013;Hema and Devi, 2015;Dang et al, 2022;), in specific locations. The intricate and variable nature of agroecosystems, coupled with the dynamism of social systems, market forces, and other factors, pose obstacles to conducting comprehensive studies.…”

The global surge in research and financial support towards understanding ecosystem services (ES) highlights their integral role in human well-being and agricultural sustainability. This approach aims for enhanced yields, resource efficiency, reduced environmental degradation, and improved landscape connectivity, integrating biophysical, cultural, and economic resources across landscapes. Despite recognizing ES values in policy decision-making, challenges persist due to issues related to value definition, valuation methodologies, and insufficient scientific studies. There are multifaceted dimensions of agroecosystem services, examining their influence and the hurdles in incorporating them into policy decisions. This keynote explores various global models of ecosystem service integration, showcasing their application in market-based policy instruments for fostering sustainable agricultural practices. Additionally, it addresses the need for comprehensive mapping of AES to inform policy formulation and highlights the growing attention towards the sustainability of production and environmental health in agricultural policy discussions.

“…Also, it provides ecosystem services that are useful in the daily subsistence and livelihood of humans, which include the provision of firewood and lumber, food, tourism, and medicine. Additionally, it administers indirect benefits such as the regulation of strong wind and waves, protection against hazards [2], filtration of water from sediments to maintain water quality [3], and provision of habitat to various migratory birds and marine organisms to increase production of marine products beneficial to the Community-Based Mangrove Forest Management Sustainability Analysis in Tagpait, Aborlan and Bacungan, Puerto Princesa City, Palawan, Philippines livelihood of the communities [2].…”
