Mangrove Mapping and Above-Ground Biomass Change Detection using Satellite Images in Coastal Areas of Thai Binh Province, Vietnam

Mangroves are recognized as a highly valuable resource due to their provision of multiple ecosystem services. Therefore, mangrove ecosystems mapping and monitoring is a crucial objective, especially for tropical regions. Thai Binh province is one of the most important mangrove ecosystems in Vietnam. The mangrove ecosystem in this province has faced threats of deforestation from urban development, land reclamation, tourism activities, and natural disasters. Recently, to maintain the fundamental functions of the ecosystems, a large mangrove area was planted in Thai Binh. The aim of this research is to detect the change in the mangrove areas and to create an aboveground biomass map for mangrove forests in Thai Binh province. Landsat and Sentinel-2 satellite images from 1998 to 2018 were analysed using the supervised classification method to detect mangrove area change. Mangrove Above-ground Biomass (AGB) was estimated using linear regression between vegetation indices and field AGB survey. The accuracy assessment for the classified images of 1998, 2003 and 2007, 2013 and 2018 are 93%, 86%, 96%, 94% and 91% respectively with kappa of 0.8881, 0.7953, 0.9357, 0.9114 and 0.8761. The mangrove cover in the study area was estimated at 5874.93 ha in 1998. This figure decreased significantly to 4433.85 ha in 2007, before recovery began to take place in the study area, which was estimated at 6587.88 ha in 2018. In 1998, the average AGB in this study area was 22.57 ton/ha, and in 2018 it was 37.74 ton/ha with a standard error of 12.41 ton/ha and the root mean square error (RMSE) was ±12.08 ton/ha.

Abstract: Tree above-ground biomass allometries for carbon stocks estimation in the Caribbean mangroves in ColombiaIn this study, we analyzed the above ground biomass of the species Rhizophora mangle and Avicennia germinans in the mangrove ecosystem located at Marine Protected Area called in Spanish Distrito de Manejo Integrado (DMI) Cispatá-Tinajones-La Balsa, Caribbean Colombian coast. We harvest 30 individuals of each species in field and built allometric models in order to estimates of aboveground biomass with low levels of uncertainty. Our results indicate that the above ground biomass of mangrove forests in the DMI Colombian Caribbean is the 129.69±20.24Mg/ha, the equivalent to 64.85±10.12MgC/ha. The DMI has an area of 8 570.9ha in mangrove forests, and we estimated the total carbon potential stored is about 555 795.93Mg. Although there are pantropical and national above ground biomass allometric models, most of them do not discriminate mangrove forests, despite being particular ecosystems. The equations generated in this study can be considered as an alternative for the assessment of carbon stocks in above ground biomass of mangrove forests in Colombia, and can be used for analysis at a more detailed scale and they are useful for determinate the potential for carbon storage in mangrove forests like an option for the country in forest conservation and emission reduction by deforestation.

Mangrove Ecosystems

Mangrove forests are distributed in limited areas around along costlines, but they play important role in carbon fixation and carbon storafe in the tropic areas. Mangrove forests are a transitional ecosystem between land-based oceans, most of which are well-known along the tropic and subtropical coastlines. Mangrove ecosystems have an ecological function as an absorber and storage of carbon in the form of biomass. Remote sensing technology can include data spatially and temporally. This makes it easy to predict the overall extent and carbon stock. So that in the context of sustainable management of mangrove ecosystems it can be utilized to monitor mangrove carbon balance and become the basis for policy development. The objective of this study was to determine the potential above ground biomass model from ALOS-2 PALSAR-2 data in mangrove forests of Benoa Bay, Bali. In this research, the filter used is frost filtering. AGB model was constructesd by using dual-polarization L-band SAR of ALOS-2 PALSAR-2 data and field inventory plots. 40 plots were collected in the field and the allometric equation.

Abstract Rapid developments on the coastal regions have become a major thread to mangrove ecosystems. The conversion of mangrove forest into fish ponds, housing and industrial sites make the area of this unique tropical ecosystem decline significantly in the last decade. To prevent further destruction of mangrove ecosystems due to human activities, conservation programs are needed. Therefore, information on mangrove's area as well as their distribution is needed. The main objective of this research was to demonstrate the ability of remote sensing and geographic information technology to provide reliable and accurate data on mangrove forest in Surabaya and thSidoarjo regions. A Landsat TM-5 imagery (acquisition date June 4 , 2009) data was utilized to produce the map. The results showed that in the 2009 period the area of mangrove forest in Surabaya and Sidoarjo was 378.19 Ha and 1236.42 Ha respectively. However, over 73.5% area of mangrove in Surabaya and 43.25% in Surabaya were under critical conditions. Anthropogenic factors and human influence were some of the main factors that cause the condition. Activities such as illegal and uncontrolled logging, conversion of mangrove's area and the lack of people's awareness in the importance of mangrove ecosystems were also problems that lead to the massive damage of mangrove forests.
