Comparison Research on Agricultural Policy between Japan, USA and EU
Modern society continues to grapple with issues involving food, agriculture, and the environment. Our laboratory particularly focuses on research and education regarding theoretical and practical problems related to environmental concerns, such as the sustainable development of agriculture and rural economies. The agriculture, forestry, and fisheries industries, which are heavily dependent on nature, are characterized by regional differences, including region-specific history and traditions. However, in today’s advanced development of commodity economies and globalization, the nature of agricultural problems and the means to deal with them problems are heavily influenced by domestic macroeconomic conditions and government policies, as well as global competition and trading rules. Therefore, we mainly pursue the following research tracks:
1. Theoretical and empirical research on the relationship between the production activities of agriculture and forestry with environmental and natural resources issues
2. Research on Social-Ecological Systems and Food Security
3. Research on the agriculture-related regulations of WTO and other regional economic agreements and the effects of these regulations or agreements on domestic agriculture and rural economies and communities
4. Comparative studies on the agricultural policies, particularly agricultural environment policies, between major countries of the world
5. Case studies on pioneering practices in Japan and elsewhere related to environment friendly agriculture and other measures to promote rural economic development (including the promotion of the sixth industries, green tourism, Chisan Chishyou, and encouragement of new entrants into the local agriculture scene)
Interview at farm households
Farmers at Ogata village, Akita Prefecture were interviewed to get information on their history of settlement and current issues of rice production.
Resilience of Social-Ecological Systems
In face of climate change and globalization, social and ecological systems that are the base of human activities are fluctuating by interacting each other. The construction of social-ecological system that possesses resilience to unpredictable environmental change and returns its production and consumption quickly and of flexible and adaptive social system is becoming an important policy agenda.
Reforestation Policy in China
Since 1998 in north-west China, the government has started to implement the project of conversion of degraded farm land into forest and grass land. To compensate income loss of participant farmers, the government pays them some direct payments, and ecological immigration policy is adopted in some cases.
The Loss of International Competitiveness and Reconstruction of Agricultural Protection Policy in China
Recently, slowdown of Chinese economy is attracting attention, but the most noticeable problem in agricultural sector is the losing of international competitiveness accompanied by the rapid increase of price and production costs. Under the WTO and FTA regime, how to keep the domestic production and protect farmers are becoming the most important agricultural policy agenda now in China.
Total Factor Productivity Change in the Philippine Rice Sector
In the Philippines, the total factor productivities of rice sector during the late 70s and the early 80s were positive by the introduction of high-yielding varieties. However, TFP turned to be negative during the late 80s and indicated the exhausting the yield potential of HYV during the post-Green Revolution era during 1971 and 1990.
