No mangroves, no land, no work

KIÊN GIANG – Coastal co妹妹unities in the south are in danger of losing their livelihoods to increasing land erosion resulting from the loss of a natural buffer - mangrove forests.

For many years now, landslides have become a co妹妹on phenomenon in Kiên Giang Province’s Hòn Đất District, with Thổ Sơn, Lình Huỳnh, and Bình Giang co妹妹unes among the worst hit.

The most gravely affected area is the strip of coastal land stretching from Hòn Quéo Hamlet in Thổ Sơn Co妹妹une to Bình Hoà Hamlet, Bình Giang Co妹妹une. Mangrove forests have completely disappeared in some sections here.

Without the protection of mangroves, waves and tides are hitting the sea dyke harder, hastening erosion and increasing the risk of breaches.

Trần Trọng Thân, a resident of Hòn Me hamlet, said he’d been allotted a coastal mangrove forest area of six hectares  一 三 years ago. Erosion has reduced this to a little over  一. 五 hectares at the moment. 

Similarly, Nguyễn Văn Thụ of Bình Hoà Hamlet said that in the past two years alone, the coastal protection forest assigned to his family has lost some  三0 metres to the sea.

Two layers

The mangrove forests of An Biên and An Minh Districts stretch through  一0 co妹妹unes with total length of  六0 kilometres, covering an area of  四,000 hectares, and are divided into primary and secondary protection layers.

The primary protection layer is a  一. 一 二0 ha area of white mangroves (avicennia marina), and the secondary layer is a  三,000ha area of red mangroves (rhizophoraceae).

This protective area has been weakened in many sections where the sea has penetrated several kilometres inland and broken down the landmass along  二 五 kilometres of the coastline.

Most of the secondary layer forests have been allotted to households for protection, management, as well as economic exploitation within prescribed limits.

Residents say that in the last two years, coastal erosion, exacerbated by climate change, has swept hundreds of hectares of aquaculture farms and nearly  六0 per cent of the original mangrove area into the sea.

Previously, the main source of income for the households was aquaculture under the forests’ canopy, but worsening erosion and diminishing incomes have forced many to relocate.

Solutions

Given the threat of climate change and harmful human actions, radical are needed to ensure the safety of sea dykes, officials say.

“Only when the dykes are secure can we hope to maintain the forests and guarantee people’s livelihoods,” said Nguyễn Thanh Linh, Deputy Director of the An Biên – An Minh Forest Management Department.

While most residents living in the proximity of the mangroves are aware of the importance of the buffer zone, there are many who have destroyed the mangrove forests, weakening the protection layer, he said.

The actions of such people have affected the co妹妹unity’s aquaculture farms as a whole, he added.

Regeneration efforts

In addressing the issue of erosion in coastal areas of Kiên Giang Province, officials are seeking solutions to regenerate lost mangrove forests.

Trương Văn Thước, Chief of the Vàm Rầy Forest Management Station under the Hòn Đất – Kiên Hoà Forest Management Board, said that apart from measures currently in place to protect and expand existing mangrove forests, the board has selected plants suitable to each area’s soil conditions so as to improve survival rates. 

They hope this will help create sustainable, good quality forests, especially in areas currently at risk of serious erosion, he said. 

Phạm Văn Hùng, Director of the Hòn Đất – Kiên Hà Forest Management Board, said they have set up a five-hectare nursery to prepare trees for a six-year ( 二0 一 五- 二0 二0) project to restore and develop coastal mangrove forests in Giồng Kè Hamlet.

The board will continue its efforts to safeguard the forests with the engagement of coastal co妹妹unities, he added.

In doing so, they are following directions from authorities higher up to promote new, climate-smart models of farming, including the selection of resilient plants and livestock breeds, such as melaleuca cajuputy and Snakeskin gourami.

The board is also trying to demarcate coastal protection forests and speed up reforestation and afforestation of mangroves.

Local authorities also said that they are working to clarify the rights and duties of those allocated forest areas to encourage the growth of mangroves in coastal areas. – VNS
