1 Introduction
Takachihogo-Shiibayama site was certified as GIAHS in 2015 because of its distinctive
agriculture and forestry complex system. The system consists of several heritage
elements. However, what makes us recognize the elements as heritage value? In2015, the study group for Miyazaki GIAHS, aims to answer such questions, wasestablished. Each researcher of the group tries to analyze the elements by scientific Burning step of Shifting
approach. This poster is to show a part of our studies and future developments.

2 The Direction of our Studies
The members of the group share the recognition of GIAHS as shown in Fig.1. Fiveselection criteria of GIAHS certification closely linked each other, based on interaction
between human and nature. Subject to these basic understandings, the direction of
our studies is divided in two levels as follows. And, we consider that facts judgements
are more important, and facts judgements lead value judgements.

a. Facts judgements: to reveal the scientific facts of heritage elementsb. Value judgements: to judge validity of systems and institutions
based on the facts judgements

3 Present Achievements and Future Developments

z Sustainable utilization of forest resources

We have been studying heritage elements of the site
: people in the site have utilized forest resources incomprehensively as shown in Table 1. We have discussed theorder to obtain somethings for living stably
various problems at the meetings held once a month. we deeplyz Negotiation with modernization
understand the relationships between one theme and the others: people in the site have adopted new technologies
through discussion. And then, we currently have summarized theand adjusted to the changes of circumstancescharacteristics of the system of the site as at the right box.
At the present moment, the relationships between one theme and the others are no more than a tentative assumption.
Therefore, we will continue to study the values of the agriculture and forestry complex system in the site and to clarify organic
relations among heritage elements each other using an scientific methods.
