Mangrove forests provide vital ecosystem services to the surrounding communities. Despite their importance development in coastal areas impose a direct impact on reducing area cover. It is an important topic to understand the effect of coastal development on the carbon storing capacity of mangroves. This study aimed to examine the rate of erosion and accretion and estimate the amount of carbon stock change along the Cherating - Pekan coastline in Pahang Malaysia. The rate of erosion and accretion from 2006 to 2014 was determined by using SPOT 5 satellite images. The normalized difference vegetation index (NDVI) was modelled to estimate carbon stock specific to the mangrove forest. Results from the study reveal that mangroves grew at only four locations along the 87 km Cherating“Pekan shoreline. Difference analyses unveil that the coastline had undergone erosion and accretion processes with Cherating River and Penor River showing the most rapid change of 10.31 and 18.17 m/year respectively using the end point rate (EPR) method. Ular River and Kuantan River have been identified as areas prone to moderate erosion. The total carbon stock of mangroves in 2006 and 2014 was estimated at 499.78 and 520.48 t/ha respectively. This finding provides the baseline information which would be helpful and should be considered when planning the future development as well as in the management of resources along the Pahang coastline.

Abstract

Mangrove forests provide vital ecosystem services to the surrounding communities. Despite their importance development in coastal areas impose a direct impact on reducing area cover. It is an important topic to understand the effect of coastal development on the carbon storing capacity of mangroves. This study aimed to examine the rate of erosion and accretion and estimate the amount of carbon stock change along the Cherating - Pekan coastline in Pahang Malaysia. The rate of erosion and accretion from 2006 to 2014 was determined by using SPOT 5 satellite images. The normalized difference vegetation index (NDVI) was modelled to estimate carbon stock specific to the mangrove forest. Results from the study reveal that mangroves grew at only four locations along the 87 km Cherating“Pekan shoreline. Difference analyses unveil that the coastline had undergone erosion and accretion processes with Cherating River and Penor River showing the most rapid change of 10.31 and 18.17 m/year respectively using the end point rate (EPR) method. Ular River and Kuantan River have been identified as areas prone to moderate erosion. The total carbon stock of mangroves in 2006 and 2014 was estimated at 499.78 and 520.48 t/ha respectively. This finding provides the baseline information which would be helpful and should be considered when planning the future development as well as in the management of resources along the Pahang coastline.
