In recent years there is an increasing need for consciously planning agro-wastes recycle systems. Especially, at the town leve1, treatment and utilization of livestock wastes is becoming important. This is because there are already adequate faci1ities for such purposes, and also because at the farmer level there is less utilization and inadequate treatment. The planning method for livestock wastes recycling system is still in its infancy stage, hence further research is very desirable.
Therefore in this paper, we develop and suggest a regiona11y balanced diagnosis method based on analyzing of practical treatment and utilization of livestock wastes. This method was applied to a model district The results show that the method is effective, and also there are a few points that must be improved.
The proposed method is in the following order:
(1) By calculating“basic balance of regional supply and demand of compost”, we consider direction or target of the system, (2) frame hypotheses about problem of livestock wastes by interview, (3) investigation by questionnaires, (4) from those results problems of livestock wastes treatment and utilization are made clear, (5) in each livestock farmer Sevel, we calculate“basic balance of regional supply and demand of compost”and discriminate the farmers whogive influence to their soil, groundwater and so on, (6) we consider charactedstic of farmers who have problems about livestock wastes treatment and utilization, (7) and also consider characteristic of farmers who want to take their livestock wastes to compost-making facilities and we compare with discriminated farmers in processes (5) to (7).
The results obtained in this study show that the method is effective, except for a few points that must be improved. The method is considered effecdve because: (1) we can run diagnosis check for each city/ town objecdvely; (2) we can find out the directlon of improvement; (3) and finally we use these results for implementation program of regional livestock wastes recycle system.
