Coastal Blue Carbon ecosystems such as mangroves, salt marshes and seagrass beds have the highest total carbon densities of all ecosystems. Although they only represent 3% of the total forest area, carbon emissions from mangrove destruction at current rates could be equivalent to 10% of carbon emissions from deforestation. The high carbon sequestration coupled with the high risk of destruction make mangroves a prime candidate for carbon mitigation initiatives such as the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Degradation in Developing Countries (UN-REDD and REDD+).
In mangroves especially, the extreme difficulty of the terrain has hindered the establishment of sufficient field plots needed to accurately measure carbon on the scale necessary to relate remotely sensed measurements with field measurements at accuracies of 10% to 20% as required for Monitoring, Reporting and Verification (MRV) activities. Furthermore, there is a large gap in knowledge in African mangrove ecosystems.
We propose to develop a Mangrove Total Carbon Monitoring system in Gabon, Tanzania and Mozambique, three countries that are investing heavily in scientific and logistical aspects of developing MRV systems, through cooperation of the local governments and scientific institutions with international organizations such as the WWF, the UN-REDD programme, USAID, SilvaCarbon and Global Earth Observations-Forest Carbon Tracking (GEO-FCT). In Mozambique and Tanzania, The East Africa Carbon Mangrove Project was recently initiated by the US Forest Service on behalf of USAID to address carbon cycle issues relative to mangroves. The Zambezi River delta in Mozambique has been selected by WWF Mozambique and implemented by the US Forest Service as a baseline study on carbon stocks in mangroves to provide the basis for inclusion of mangroves in the Mozambique national REDD+ strategy. Through its strategic plan, Le Gabon Emergent, the Government of Gabon has committed to pursue sustainable development and a Gabon Forest Carbon Assessment has been initialized across the country. As part of these 3 initiatives there will be airborne lidar data acquired and made available in mangrove sites in all three countries.
We will use a suite of commercial off-the-shelf datasets to estimate forest biomass, extend and cover change over time, including airborne LiDAR, Synthetic Aperture Radar (SAR) and Very High Resolution optical (VHR). Our proposed methodology takes into account that most MRV systems require repeated measurements of carbon stocks and acquiring airborne lidar data on a regular timeframe is costly and impractical. Thus we propose to use commercial spaceborne data from optical sensors as well as Synthetic Aperture Radar (SAR) missions. We will to use the most advanced 3-D remote sensing technology - Polarimetric Interferometric SAR or Pol-InSAR - as an operational technology that can augment, or even replace, costly acquisitions of Lidar data for MRV activities. We propose a 3D mapping methodology to quantitatively characterize forest structure and extent as well as change over time and to inform the field measurements site stratification and location.
Our research strategy consists in using the airborne lidar to upscale field estimates of biomass to a larger scale and enable validation of TanDEM-X derived estimates of canopy height and biomass. We will develop a present day mangrove extent map using Landsat, SAR (ALOS-2) and Very high Resolution commercial optical data then adapt global forest change mapping algorithms to include mangrove forests and develop a timeseries of mangrove change in all three countries from 1990 to the present day.
Finally we will coordinate a Mangrove Carbon Working Group composed of in-country and US experts to coordinate, disseminate and inform field, remote sensing and GIS experts on the use and generation of the data products from this study.

Description: This dataset provides several estimates of aboveground biomass from various regressions and allometries for mangrove forest in the Zambezi River Delta, Mozambique. Plot level estimates of aboveground biomass are based on extensive tree biophysical measurements from field campaigns conducted in September and October of 2012 and 2013. Aboveground biomass estimates for the larger area of mangrove coverage within the delta are based on (1) the plot level data and (2) canopy structure data derived from airborne LiDAR surveys in 2014. The high-resolution canopy height model for the delta region derived from the airborne LiDAR data is also included.

Spatial Extent: Mangrove forested land of the Zambezi River Delta, Mozambique
Spatial Resolution: 1 m
Temporal Frequency: Seasonal
Input Data Products: Airborne Lidar, and field measurements. LiDAR data was acquired by Land Resources International (Pietermaritzburg, South Africa). The airborne survey comprised an approximate area of 115 km2 in the Zambezi Delta region, Mozambique, with a point density that ranged between 5 - 7 points per m2 (Lagomasino et al., 2016).
Algorithm/Models Used: Field-based canopy height and carbon stock estimates were inventoried using a stratified random sampling design that took into account forest canopy height classes determined from the Mozambique mangrove canopy height data product derived from SRTM and GLAS data (Fatoyinbo et al., 2008).
Total aboveground biomass (AGB) was estimated using the generalized Komiyama et al. (2005) mangrove allometry, the pantropical Chave et al. (2005) allometry, and the site-specific Njana et al. (2015) allometry derived for Tanzania as there is no site-specific published allometry for the Zambezi region.
Evaluation:
Intercomparison Efforts/Gaps: Comparison of field and LiDAR height metrics showed that the airborne survey data was highly correlated with field estimates of forest canopy height at the plot level across the entire range of sampled canopy heights. The strongest correlation between field and airborne survey metrics were found between LiDAR H100, LH, and Field H100, with 93% accuracy prediction between the airborne and field survey metrics.

Product Title: Global Mangrove Distribution, Aboveground Biomass, and Canopy Height
Start Date: 01/2000End Date: 08/2014
Description: This dataset characterizes the global distribution, biomass, and canopy height of mangrove-forested wetlands based on remotely sensed and in situ field measurement data. Estimates of (1) mangrove aboveground biomass (AGB), (2) maximum canopy height (height of the tallest tree), and (3) basal-area weighted height (individual tree heights weighted in proportion to their basal area) for the nominal year 2000 were derived across a 30-meter resolution global mangrove ecotype extent map using remotely-sensed canopy height measurements and region-specific allometric models. Also provided are (4) in situ field measurement data for selected sites across a wide variety of forest structures (e.g., scrub, fringe, riverine and basin) in mangrove ecotypes of the global equatorial region. Within designated plots, selected trees were identified to species and diameter at breast height (DBH) and tree height was measured using a laser rangefinder or clinometer. Tree density (the number of stems) can be estimated for each plot and expressed per unit area. These data were used to derive plot-level allometry among AGB, basal area weighted height (Hba), and maximum canopy height (Hmax) and to validate the remotely sensed estimates.

Product Title: CMS: Mangrove Forest Cover Extent and Change across Major River Deltas, 2000-2016
Start Date: 01/2000End Date: 12/2016
Description: This dataset provides estimates of mangrove extent for 2016, and mangrove change (gain or loss) from 2000 to 2016, in major river delta regions of eight countries: Bangladesh, Gabon, Jamaica, Mozambique, Peru, Senegal, Tanzania, and Vietnam. For mangrove extent, a combination of Landsat 8 OLI, Sentinel-1 C-SAR, and Shuttle Radar Topography Mission (SRTM) elevation data were used to create country-wide maps of mangrove landcover extent at a 30-m resolution. For mangrove change, the global mangrove map for 2000 (Giri et al., 2010) was used as the baseline. Normalized Difference Vegetation Indices (NDVI) were calculated for every cloud- and shadow-free pixel in the Landsat 5 TM, Landsat 7 ETM+, and Landsat 8 OLI collection and used to create an NDVI anomaly from 2000 to 2016. Areas of change (loss or gain) occurred at the extremes of the cumulative anomalies.
