Although qualitative research contains a broad range of possibilities for theorization, there is no common standard to measure the degree of achievement of papers. By contrast, quantitative studies have shared methodology for statistics and numerical results that enable easier comparison between papers. In my experience reviewing submitted qualitative research papers, the important points are to set up the theoretical framework that illustrates the relationships among the introduced concepts at the beginning, to include a clear research question, to deploy a relevant empirical case study or studies, to interpret them through the use of the concepts initially introduced, and to identify new implications for future research. The paper must be equipped with several sorts of validities and, in some instances, causality as well. Social science studies of agriculture and forestry have a mission to solve the many real challenges, which is inherent in applied sciences. In this sense, the method of action research is required in the qualitative research of our field under the current conditions of rural degradation of agricultural production and local societies. Despite the difficulties posed by the new research method like action research, qualitative research can provide valuable perspectives and benefits for designing agriculture and forestry of the future.

Simulation is a thought process that foresees the uncertain future and guides for a better future by altering the present behavior and social system on the basis of the information received. Currently, when agriculture and forestry are changing rapidly, and its future is uncertain, research using simulation is beneficial for developing regional agriculture and forestry economics. In Japan, this is particularly relevant when the significance of agriculture and forestry is decreasing. It is a critical mission of the regional agricultural and forestry economic associations to not only address the problems in reality but also engender a drastic paradigm shift and innovation within the region. Therefore, it is essential to integrate knowledge from not only narrow economics but also various academic fields and to urgently publish new research results. The present study introduces a research example using multi-agent simulation and solution of a traveling salesman’s problem using several simulation approaches. Furthermore, it also recommends further studies using simulation in the future by exhibiting many useful experiences as encountered by the author in the process.

This study analyzes the main factors affecting the creation of additional income among the 55 good and excellent formal silk weaving groups in Northeast Thailand. A multiple regression analysis was conducted to establish statistically significant variables among the factors. The results indicate that it is important for the groups to endeavor to increase the percentage of group members who are younger than 50 years old by promoting the participation of young people. It is also important to activate traditional knowledge transfer by increasing opportunities for skillful members to teach younger members and to activate sales activities by improving the functions of marketers.
