Some key issues for the East Asian food sector

This collection of five papers constitutes the second of two volumes on Japanese agricultural policy. The first paper, by Masayoshi Honma, looks at agricultural policy reform in Japan from a political economy perspective, especially in respect of the implementation of the Uruguay Round Agreement and the next round of negotiations. Ray Trewin then picks up the implications of East Asian approaches to food security for the next WTO round, mainly contrasting Japan’s self-sufficiency approach with China’s more open trade and investment policies. Regional arrangements to address food security are promoted in the paper. A paper by Malcolm Bosworth and Leanne Holmes develops and applies a framework for assessing the costs and benefits of Japan’s sanitary and phytosanity (SPS) measures, especially in respect of the WTO SPS agreement. The implication for Japan’s SPS policies are drawn out in the paper. Randy Stringer looks at the constraining role of land institutions and regulations, which are similar in East Asia, on structural adjustment, especially in agriculture, and the costs and benefits of such institutions and regulations. The final paper, by Yoshihisa Godo, explains, for the first time in English, the reasons behind the small size of Japanese farming that has constrained productivity, and the distortions in land use and farm output caused by farmland use regulations and taxation. Desirable directions for Japanese agricultural policy reform are also discussed in the paper. It is expected that this collection of papers will assist Australian and Japanese agencies and businesses, and those from other countries, to develop strategies for improving Japanese agricultural policies during the upcoming WTO round

Excitation of low-frequency QPOs in black-hole accretion

We study possible mechanisms of excitation of quasiperiodic oscillations in the accretion flow of black hole accreters in their hard spectral states, in the context of the `truncated disk' model. Quasi-spherical oscillations of the inner ion-supported accretion flow (ISAF) can be excited by the interaction of this hot flow with the cool disk extending outward from it. The fundamental mode of (p-mode) oscillation is most easily excited, and has a frequency near the Kepler frequency at the inner edge of the cool disk. The strongest excitation mechanism is a feedback loop involving cooling of the ISAF by soft photons from the cool disk and heating of the cool disk by the ISAF, while synchrotron emission can be a relatively strong damping effect. Growth times are computed by detailed Comptonization calculations of the interaction of an idealized ISAF with a cool disk. Typical growth times as short as a few dynamical times are found, while amplitudes can be as large as 10%.Comment: 11 pages, 5 figures, accepted for publication in A&

Presentation tools on the web-based communication system

With the development of network communication technology in recent years, there have been many successful examples of architectural design education using the Web based support system. Authors have developed the information exchange and sharing system, and make an improvement on it through the collaborative design studio. This paper describes the new function for collaborative design team. 

A way forward for Japanese agriculture

Under the GATT Uruguay Round Agreement on Agriculture (URAA) that came into effect on 1 January 1995, Japan pledged to convert non-tariff barriers into tariff equivalents for 28 commodities. The implementation of the Agreement on Agriculture triggered domestic policy reform. In July 1999 the Japanese Diet passed the Basic Law on Food, Agriculture and Rural Areas, which replaced the Agricultural Basic Law of 1961. The new law outlines the direction and principles of Japanese agricultural policy for the 21st century and is more consistent with the World Trade Organisation (WTO) regime. However, these measures represent only the start of agricultural reform. Where is Japanese agriculture headed and do these changes represent a significant movement toward real reform? Agricultural policymaking in Japan reflects political power struggles. Agriculture is a highly protected sector, and as in many other industrialised countries, protection has increased as agriculture’s contribution to the economy has shrunk. Consumers – a larger and less politically organised group – tolerate agricultural protection as long as their incomes are rising, while agricultural producers are far smaller in number and lobby strongly as they have far more to lose. Pressure from foreign producers is a strong countervailing force against domestic interests that support agricultural protection, and explains why agriculture was one of the most important areas in the Uruguay Round negotiations
