Assessment of the status of eco-economic model development in the Kon river basin, Binh Dinh province

The eco-economic model is one of the economic development orientations associated with environmental protection, ensuring sustainable development for the territories. According to the eco-economic approach, the article has assessed the current status of developing eco-economic models in the Kon river basin, Binh Dinh province by the method of participatory rural appraisal and cost-benefit analysis based on three values: present value (PV), net present value (NPV), benefit-cost ratio (BCR). The results show the households have applied many different eco-economic models in agricultural and forestry production (18 types of models). Most of the models in the basin have components: fields, gardens, and barns. The model of rice field - garden - barn (Ru-V-C) accounted for the highest percentage (33.07%). The model of rice field - garden - pond - barn - forest (Ru-V-A-C-R) has the highest average annual profit of 237 million VND\year after discounting. Models with 3-4 components have created a link in the material-energy cycle in production, taking advantage of by-products, and protecting the environment. The evaluation results are the basis for proposing eco-economic models suitable to the potential and resources of the Kon river basin, Binh Dinh province.
