Mapping of carbon stocks plays important role to study the climate change. The understanding of carbon stocks dynamics on the earth leads us to prepare the climate change mitigation and adaptation. This paper was aimed to analyze mangrove carbon stocks using radar remote sensing data of ALOS PALSAR dual-polarizations. The study area is in Southeast Sulawesi (Lainea District). Two dates acquisition of ALOS PALSAR were used to obtain carbon stocks spatial distribution through polarimetric (PolSAR) and polarimetric-interferometry (PolInSAR) method. Tweenty sample plots were established in study area for validation. Field survey conducted to measure Diameter at Breast Height (DBH) and mangrove tree height to obtain actual carbon stocks. The result of the research indicated that the PolSAR method using HV polarization was suitable to map mangrove carbon stocks which can be estimated up to 40 t ha-1 (R2=0.8982), while using PolInSAR can be estimated up to 60 t ha-1 (R2=0.6606). However, the disadvantage of PolSAR method which indicated saturation problem of backscatter correlation (HH and HV) to carbon stocks volume. Using the PolInSAR, we obtained mangrove tree height in the site distributed from 0 to 25 meters which less than 20 meters heights dominated the study area.

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.

At the tenth Convention on Biological Diversity (CBD) Conference of the Parties (COP) held in Nagoya 2010, the parties agreed that they would by 2020 enhance 'ecosystem resilience and the contribution of biodiversity to carbon stocks …, through conservation and restoration, including restoration of at least 15 per cent of degraded ecosystems, thereby contributing to climate change mitigation and adaptation and to combating desertification' (Aichi Target 15, Decision X/2 (Strategic Plan for Biodiversity 2011-2020)).

While closed canopy forests have been an important focal point for land cover change monitoring and climate change mitigation, less consideration has been given to methods for large scale measurements of trees outside of forests. Trees outside of forests are an important but often overlooked natural resource throughout sub-Saharan Africa, providing benefits for livelihoods as well as climate change mitigation and adaptation. In this study, the development of an individual tree cover map using very high-resolution remote sensing and a comparison with a new automated machine learning mapping product revealed an important contribution of trees outside of forests to landscape tree cover and carbon stocks in a region where trees outside of forests are important components of livelihood systems. Here, we test and demonstrate the use of allometric scaling from remote sensing crown area to provide estimates of landscape-scale carbon stocks. Prominent biomass and carbon maps from global-scale remote sensing greatly underestimate the “invisible” carbon in these sparse tree-based systems. The measurement of tree cover and carbon in these landscapes has important application in climate change mitigation and adaptation policies.

Abstract Biodiversity and climate change are interrelated, so a coordinated approach is needed to cover it by focusing on how landscapes provide many benefits. The Mbeliling landscape, Flores is the smallest management unit in an ecological perspective, essential for the conservation and preservation of biodiversity, especially for the endemic birds of Flores. Efforts to preserve biodiversity are also expected to contribute to climate change mitigation and adaptation. The study aims to produce data and information on biodiversity and potential carbon stocks at the land cover of the Mbeliling landscape. Desk study and field survey were used to answer research questions. The Mbeliling landscape has eight types of tree vegetation land cover that can serve as carbon sinks and the habitat for four species of Flores endemic birds. Approximately 139 species of vegetation with the total carbon stocks could potentially absorb the carbon dioxide in the atmosphere of ± 103.63 Mt CO2-e. The type of land cover significantly influences carbon stocks. The land cover with forest category in the Mbeliling landscape has the most extensive carbon stock among other land cover types. This result can be used as a reference in managing the Mbeliling landscape in integrating efforts to conserve biodiversity and mitigate climate change through the REDD+ scheme.

Change Mitigation

As users of forest products and guardians of traditional knowledge, women have always been involved in forestry. Nevertheless, their access to forest resources and benefits and participation in forest management is limited compared to mens despite the fact that trees are more important to women, who depend on them for their families food security, income generation and cooking fuel. This guide aims to facilitate the incorporation of a gender lens in climate change mitigation and adaptation operations in forests, with special attention to those framed in REDD. This guide addresses four themes value chains, environmental payment schemes, firewood and biodiversity that relate directly to 1) how climate change impacts affect women in the forest and 2) how mitigation and adaptation measures affect womens access to resources and benefits distribution.
