| Abstract | The CEA analysis in this study involved three phases: the first phase selected components of a cumulative effects assessment, including (a) identification of sources of environmental impacts (b) selection of a set of valued ecosystem components and the multifunction(services) affected, and (c) use of a set of key indicators to examine cumulative effects arising from the aggregate of human activities. The second phase was the impact prediction using: 1) cumulative effects assessment through expert opinion; 2) Participatory Rural Appraisal (PRA); The third phase described and evaluated the mitigation and monitoring measures. Quantifying the predicted impacts of the cumulative effects using binary logistic regression and other statistical tests provided veritable picture of the state of wetland ecosystems. Mitigation and monitoring measures can be focused on several specific driver’s (stressors)which possibly reinforce each other to avoid cumulative effects which can be determined by correlating all the drivers and multifunction using Spearman’s correlation(at p>0.01)This mitigation measure can be effective specifically at developing worlds in which financial constraints prevail. The present thesis study to quantify the cumulative effects of the identified drivers on the multifunction of the Hoi An estuarine with focus on Truong Giang river. Furthermore, it was found through computation that pollution, industrial, domestic had high cumulative effects on the ecosystems. The production function of the ecosystems 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. |
