Abstract The mangrove vegetation in the coastal environment has a vital role, especially as a regulation for CO2 and O2 gas exchange. Mangrove revegetation has significant relevance for local-scale climate change mitigation. This study aims to assess and describe the success of mangrove revegetation in mitigating climate change at a local scale. Ecological data research methods are through surveys, observations and transect methods. Furthermore, the collection of social data through surveys, interviews, questionnaires, and Focus Group Discussions (FGD). Meanwhile, the research data were analyzed using descriptive statistical analysis, and analysis of the mangrove vegetation structure through frequency, density, cover, and essential value index analyses. The study results found seven types of mangroves, namely Sonneratia alba, Rhizophora stylosa, Rhizophora apiculata, Avicennia marina, Bruguira gymnoryzha, Lumnitzara racemosa, and Ceriops tagal. Sonneratia alba and Rizoporastylosaare species with the highest importance value of 194.04 where S. alba found Poton Bako and R. Stylosa found in Tanjung Luar. As for social data and knowledge, people in areas with a distance of 0-50 meters from mangrove forest have a better understanding than people living in areas with an average percentage value perspective of 52 %. Then, most respondents agreed that mangroves could prevent abrasion and reduce heat temperatures, with the percentage of respondents responding more than 41 % and 61 %, respectively in all locations. Based on the essential value index and respondents’ perceptions, it can be concluded that the Sonneratia alba and Rizopora Stylosa are species that have the highest ecological function because they have good adaptability in the coastal areas of South Lombok making them suitable as species for revegetation programs in South Lombok, and for the next revegetation program should be involving people who are close to mangrove forests because they are the ones who know and feel the benefits of mangrove forests.

Nypa fruiticans, commonly known as Nipa Palm, is a species of palm native to the coastlines and estuarine habitats of the Indian and Pacific Oceans. In Indonesia, nipa palm covers about 700,000 ha, while, in South Sumatra, the Nipa Palm is a natural component of mangrove forests and covers extensive areas along the coast, estuaries, and riparian zones of rivers. About half of the natural nipa palm ecosystem in South Sumatra has been disturbed by human activities and requires restoration. Since Nipa Palm can be used to produce nipa palm sugar, natural nipa palm forests have the potential to generate sustainable rural livelihoods for those living in the lowland zone. More recently, nipa palm has been identified as a potential source of renewable energy. The sugar rich sap can be used to produce ethanol, a biofuel. Because of this potential, the KELOLA Sendang Project is exploring the potential of nipa palm for ecosystem restoration and climate change mitigation, sustainable rural livelihoods and renewable energy.

Abstract Background: Mangrove forests have gained recognition for their potential role in climate change mitigation due to carbon sequestration in live trees, and carbon storage in the sediments trapped by mangrove tree roots and pneumatophores. Africa hosts about 19% of the world’s mangroves, yet relatively few studies have examined the carbon stocks of African mangroves. The available studies report considerable differences among sites and amongst the different pools of carbon stocks. None considered the effects of seaward distance. We present details of AGC and SOC carbon stocks for Lindi in Tanzania, and focus on how these values differ with increasing seaward distance and, how our results compare to those reported elsewhere across Africa.Results: AGC ranged between 11-55Mg C ha-1, but was not significantly affected by seaward distance. SOC for 0-1m depth ranged from 154-484, with a mean of 302 Mg C ha-1. SOC was significantly negatively correlated with seaward distance. Mangrove type (estuarine/oceanic), soil erosion, soil depth may explain these differences We note important methodological differences in previous studies on carbon stocks in mangroves in Africa. Conclusion:This study indicates that seaward distance has an important effect on SOC stocks in the Lindi region of Tanzania. SOC should be fully incorporated into national climate change mitigation policies. Studies should report seaward distance and to describe the type of mangrove stand to make results easily comparable across sites and to assess the true value of Blue Carbon in Africa. We recommend focusing on trees >10cm diameter for AGC, and sampling soils to at least 1m depth for SOC, which would provide a more complete assessment of the potentially considerable mangrove carbon store.

Mangrove forests store and sequester large area-specific quantities of blue carbon (Corg). Except for tundra and peatlands, mangroves store more Corg per unit area than any other ecosystem. Mean mangrove Corg stock is 738.9 Mg Corg ha−1 and mean global stock is 6.17 Pg Corg, which equates to only 0.4–7% of terrestrial ecosystem Corg stocks but 17% of total tropical marine Corg stocks. Per unit area, mangroves sequester 179.6 g Corg m−2a−1 and globally about 15 Tg Corg a−1. Mangroves sequester only 4% (range 1.3–8%) of Corg sequestered by terrestrial ecosystems, indicating that mangroves are a minor contributor to global C storage and sequestration. CO2 emissions from mangrove losses equate to 0.036 Pg CO2-equivalents a−1 based on rates of C sequestration but 0.088 Pg CO2-equivalents a−1 based on complete destruction for conversion to aquaculture and agriculture. Mangrove CO2 emissions account for only 0.2% of total global CO2 emissions but 18% of CO2 emissions from the tropical coastal ocean. Despite significant data limitations, the role of mangrove ecosystems in climate change mitigation is small at the global scale but more significant in the tropical coastal ocean and effective at the national and regional scale, especially in areas with high rates of deforestation and destruction.
