The assessment of mangrove biomass and carbon in West Africa: a spatially explicit analytical framework

Estimating mangrove aboveground biomass from airborne LiDAR data: a case study from the Zambezi River delta

“…This model was applied to continental scale estimates of mangrove canopy height generated from the Shuttle Radar Topography Mission (SRTM), a spaceborne InSAR (Interferometric Synthetic Aperture Radar) dataset, combined with spaceborne Lidar from the GLAS (Global Laser Altimetry System) instrument in Fatoyinbo and Simard (2013). Similar, more site specific models have been used to estimate AGB from SRTM in the Florida Everglades (Simard et al 2006, Colombia , Mozambique (Fatoyinbo et al 2008), West Africa (Tang et al 2016) and Indonesia (Aslan et al 2016). AGB estimates may vary greatly depending on the selection of the allometric models, as the estimates are dependent on (a) the availability of a specific model for the species and region of interest, (b) whether the allometry was intended as a global, national or regional model, (c) which field-based parameters (e.g.…”

Tropical wetlands, climate, and land-use change: adaptation and mitigation opportunities

“…Mapping tropical wetland ecosystem C stocks needs to consider both the aerial coverage of wetlands and their C density. Remote sensing and ground truthing such as that used in the Tang et al (2016) paper appears to be the approach that will allow us to most efficiently map aerial extent. Similar studies need to be conducted globally for both mangrove and peatland aerial coverage in the tropics.…”

“…Unlike the results reported by Adame and Fry (2016), stable isotopic signatures showed that the organic matter is likely a mix of mangrove and marine sources, with mangrove-derived sources contributing 42-58 %. Tang et al (2016) used geospatial techniques to estimate mangrove extent, mangrove biomass and C stored in biomass in nine West African countries. They used NASA derived products to estimate mangrove canopy height and spatially explicit analysis based on allometric equations to convert to both above-and belowground biomass and associated C. Overall the total mangrove biomass and C for West Africa were estimated as 273 Tg and 136 Tg, respectively.…”

“…This special issue on tropical wetlands has 11 papers that went through the normal journal review process and are presented starting with a paper by Hribljan et al (2016) focusing on high elevation peatlands in Ecuador, followed by a paper that compares C stocks in tropical peatlands and mangroves in Mexico (Adame and Fry 2016), and then a series of 9 papers assessing mangrove dynamics from Africa Tang et al 2016;Trettin et al 2016), South and Latin America Kauffman et al 2016;McFadden et al 2016), and Southeast Asia MacKenzie et al 2016). The final paper is a global review on impacts of rising ocean water levels on mangrove ecosystems ).…”

Monitoring of Eco-Restoration of Mangrove Wetlands through Time Series Satellite Images: A Study on Krishna-Godavari Delta Region, East Coast of India

“…While the mangrove vegetation was being degraded by several natural and anthropogenic causes, considerable efforts are also being made for conservation, restoration and sustainable use of mangroves, which in turn improves the carbon stocks (Tang et al 2016). Mangrove reforestation programs need to consider selection of suitable species for a given environmental conditions such as the topography and soil condition (Miyagi et al 2014).…”
