“…In this study, soil carbon stocks in the fringe and interior mangrove forests contributed up to 86.82% and 87.97% to TECS. This result is in line with previous studies (Ardhani et al, 2020;Hanggara et al, 2021) that show soil to be the largest carbon pool. Due to the significant contribution soil carbon makes to TECS, these stocks are threatened if mangrove soil is disturbed (e.g., conversion from mangrove to aquaculture pond).…”

Aquaculture is one of the main drivers of mangrove loss across Southeast Asian countries. The conversion of mangroves to aquaculture generates substantial loss of carbon stocks and reduces carbon storage capacity. Here, we present total ecosystem carbon stocks (TECS), carbon dioxide (CO2) and methane (CH4) effluxes obtained from mangrove forests (fringe and interior mangroves), silvofishery aquaculture ponds (dense and sparse mangroves), and non-silvofishery aquaculture ponds in Sawah Luhur, Banten, Indonesia. We found no significant difference in TECS across five land uses, ranging from 261 ± 14 Mg C ha-1 in non-silvofishery ponds to 574 ± 119 Mg C ha-1 in fringe mangroves. Most of these stocks were found in the soil carbon pool (87%) in fringe and interior mangroves. However, the conversion of mangroves to aquaculture ponds resulted in soil carbon loss from -6% to 60%. The highest soil CO2 effluxes during dry and wet seasons were observed in interior mangroves (151 ± 12 mg CO2 m-2 h-1). The highest soil CH4 effluxes were found in fringe mangroves with 0.13 ± 0.04 mg CH4 m-2 h-1. The highest aquatic CO2 and CH4 effluxes were found in dense silvofishery ponds, at 118 ± 7 mg CO2 m-2 h-1 and 0.38 ± 0.04 mg CH4 m-2 h-1, respectively. Our findings suggest that land use that includes mangroves (i.e., mangrove forest and/or silvofishery ponds) tends to have higher carbon stocks, soil, and aquatic CO2 and CH4 effluxes, compared to aquaculture ponds without mangroves. It is therefore crucial to maintain mangroves for natural carbon capture and storage through carbon stock enhancement.

“…Environmental, economic, social, and infrastructure considerations are integral to the decision-making process of small-scale fishing families in Demak when responding to the challenges of sea level rise and flood events [15,16,22,26]. Initially, these families tend to adopt adaptive strategies as proactive measures before contemplating permanent migration.…”

This study explores the adaptation process of small-scale fishing families in Demak, Java, in response to sea level rise and tidal floods. Qualitative research methods are used to investigate the factors influencing families’ decisions to relocate. Findings indicate that families employ home elevation as a short-term adaptation measure, but severe floods eventually lead to the challenging decision of permanent migration. The study highlights the interplay of physical, social, and economic factors in shaping migration decisions. While short-term strategies provide partial relief, migration emerges as a vital long-term resilience strategy. Mitigation efforts involve coastal protection, wetland restoration, land use planning, and climate change adaptation measures. The study emphasises the need for tailored, context-specific strategies and integration of sea level rise considerations into broader climate change mitigation efforts. Overall, understanding migration decisions and implementing targeted disaster mitigation strategies are crucial for enhancing the resilience of coastal communities facing sea level rise.

“…According to previous research, the erosion rate of coastal regions in the Sayung subdistrict ranged from 4 to 65 meters per year, with an average of 25 meters per year (Muskananfol, Supriharyono, & Febrianto, 2020). Massive conversion of mangrove forests to aquaculture ponds contributes to the degradation of coastal areas and the decline in mangrove species' composition and physical structure (Ardhani, Murdiyarso, & Kusmana, 2020). Additionally, based on the geomorphological circumstances of Sayung's coastal region, which has a high degree of erosion insecurity and an inundation intensity of 3.5 hours per day, these difficulties encourage people to adapt to these conditions (Sarasadi, Rudiarto, & Faradila, 2021).…”

Climate change has a greater effect on the long-term viability of coastal environments and people’s livelihood. The idea of using ecosystems to help people deal with the effects of climate change is becoming more common at the international, national, and local levels, especially when it comes to spatial planning. So, learning about spatial planning-based ecosystem adaptation (SPBEA) is important for early careers because they will be the ones who have to deal with the decisions made now. Coastal communities must also understand the steps they can take to lessen the effects of coastal disasters in their area. This study looks at how the SPBEA concept can be taught to early-career practitioners and coastal communities through training and workshops, and the effectiveness of online training in transferring knowledge. The method of training used the hybrid method for comparison. A hierarchical approach was taken, starting from the compilation of SPBEA teaching materials, followed by SPBEA training for early-career practitioners to generate SPBEA zoning and transferring the training results to the coastal communities. Online training is not as good as offline one, but it was advantageous for the participants. Indeed, the pond-farming community was excited about the implementation of SPBEA.
