Mangrove trees act important roles in the coastal ecosystems, protecting community against high-tide and\ud
storms, controlling land erosion and providing fish breeding ground. In the last few decades, the massive area has\ud
devastated due to commercial shrimp and fish ponds development. To rehabilitate the coastal ecosystems, some\ud
mangrove has been planted with spacing distances of 1x1 m with minimal forest management. Those dense-spaced\ud
stands enhanced light competitions and inhibit growth. These poor quality and immature stands that reach an early\ud
climax in 10-15 years were observed in two adjacent sites near Nam Dinh and Thanh Hoa in northern Vietnam, where\ud
Kandelia candel were planted. To cultivate the resurgent stands and increase their growth, thinning mangrove is\ud
essential. Stand densities of the mangrove trees with and without the thinning practice were 17,800 and 5,200 trees ha-1,\ud
respectively. Their potential of the maximum above-ground biomass were 303 and 239 Mg ha-1, respectively. However,\ud
quality of the single tree was largely different whether or not thinning practice is conducted, as the thinned one of 46 kg\ud
tree-1 was about three times higher than the non-thinned of 17 kg tree-1. The thinning practice enhances stand biomass\ud
growth with improved growth condition in the forest, which advances carbon sequestration for the climate change\ud
mitigation. The cultivated trees also ensure the climate change adaptation of coastal protection, fishery products and\ud
bio-diversity. Synergizing mitigation and adaptation strategies with the mangrove thinning would enhance the benefits\ud
for coastal communities most vulnerable to climate change
