| Abstract | Vietnam has a long coastline, supporting a large area of mangroves. Large losses of mangroves have occurred for decades, leading to coastal erosion, decline of fishery resources and other environmental consequences. The mangroves, including nipa palm forests around Hoi An City, one of the popular tourism destinations in central Vietnam, has also experienced these impacts. The present thesis study to quantify the cumulative effects of the identified drivers on the multifunction of the Hoi An delta wetland ecosystems by ranking and averaging method resulted the average cumulative effects were moderately high. Furthermore, it was found through computation that pollution, hydropower and mining had high cumulative effects on the delta ecosystems. The production function of the mangrove ecosystem was highly affected by the primary direct drivers (stressors), followed by the regulation and information functions. These results imply that, if no mitigation measures will be done, continued degradation of mangroves’ multifunction will lead to dissatisfaction of human well-being specifically food, security and health. The data indicated that at the given current rate of wastewater discharge by the Hoi An city municipality, the danger of increasing wastewater discharge in the river can impact on the mangrove ecosystems provided no mitigation measures will be implemented. Products from nipa palm are having an increasing economic value and tourists began to appreciate the scenic view of nipa palm forest. These are important elements to encourage the plantation and protection of nipa palm. This will relate to a more productive area and more income to the local people. As a result, the present study it is proposed to rehabilitate approximately 300 ha of additional nipa forest ecosystem in the Cam Thanh Commune area. |
