| Outline of Final Research Achievements |
This study investigates an optimal allocation of conservation agriculture by combining genetic algorithm, distributional watershed simulation model, and lake ecosystem simulation model. Our results show that, in relatively small watershed, spatial allocation of conservation agriculture is less important in terms of lake ecosystem restoration. Although this might be due to the scale of the watershed, our results are uncertain in terms of the extent of generalization. Further research would be highly needed by focusing on other small watersheds with different conditions and larger-scale watersheds.
