| Research Abstract |
This study aimed to identify issues to be discussed to realize local-scaled recycling systems of organic materials in urban fringe landscapes by examining three major issues as follows.
1.Small-scaled material cyclic system between urban and rural land uses in urban fringe landscapes
A novel evaluation framework of farmlands in a rural-urban mixed area was developed towards a sustainable agricultural system. The object of the framework was to establish a material circulation system that utilizes kitchen waste from houses to fertilize nearby farmlands. The framework was then applied to Kokubunji City in the Metropolis of Tokyo, a representative rural-urban mixed area. The framework illustrated that the degree to which farms may obtain sufficient compost is a factor of the size of the farms and their interspersing rate. The smaller the farms and the more interspersed they are, the greater the sufficiency of compost is. Meanwhile, farm products in small-scale farmlands with sufficient compo

st satisfy the demand of those households providing kitchen waste.
2.Effective interactions of consumers and farmers in a recycling system between urban and rural land uses in urban fringe landscapes
Attempts to create effective recycling systems have encountered difficulties in fostering cooperation between groups of consumers and farmers. This is because of a lack of trust between both groups. For example, farmers do not trust unknown consumers to make good-quality compost. The objective of this research is to assess how willingly farmers and consumers cooperate with each other. This will enable policy-makers to understand how a recycling system can be made more effective. We argue that location has an important role to play in building trust. Overall the results show the importance of locating close to farmer's activity.
3.Optimum maintenance schemes of satoyama in urban fringe landscapes to enhance biomass production
Satoyama woodlands located in urban fringe areas have lost their economic viability to be maintained and thus been abandoned for decades. However, recent attention on the biomass as an alternative renewable resource restored public attentions on satoyama, which may become one of indispensable sources of biomass. The aim of this study is to estimate the potential amount of biomass provided by satoyama according to several maintenance schemes. The study estimated that 1.22t/ha to 5.22t/ha of biomass, which can be transformed into electric power for 1,300 to 5,200 households, will be provided annually if an appropriate maintenance has been conducted.
