Development of optimization model for budget distribution to countermeasures against livestock manure management (study on reasonable budget planning for effective utilization of livestock manure)

In this research, the model for budget allocation to countermeasures against livestock manure oversupply problem was developed to contribute to the establishment of reasonable policy decision-making. The model was based on the multi-criteria analysis, which was often applied to the evaluation of public works projects. The developed model was applied to Maebashi city, Gunma Prefecture as a case study. As a result, the most effective countermeasure was the combination of "Feed Production" and "Methane Fermentation" to improve the environmental and social benefits, which had high priority for residents in Maebashi city. And "Livestock Reduction" was also an effective countermeasure in case that there was leeway in the budget. It seemed to be difficult to execute "Livestock Reduction" In Japan. However, the expected benefits were quite large especially in water pollution, global warming and acidification if that countermeasure could be executed. Therefore, a promotion of consensus building between government and residents through environmental education was expected.
