Basic food staples are essential for sustainable existence. In Japan, the most basic and nutritional food staples are rice and soybeans. Farming with organic substances; non-usage of chemical fertilizers; non-adoption of transgemc seeds; 'universal farming for survival' ; 'local products for local consumption'; citizens' gardens of land in dues/rented fields in agricultural areas, a symbiosis between city and country residents; and 'half-farming/ half-engaging favorite occupation' are the appropriate methods for ensuring self-sustenance in Japan. These methods are expanded not only in Japan, but also in other Asian countries, with their similar geographical conditions. Thsting and verification of the above methods in Japan and comparison of such methods to agricultural methods in Laos and Bhutan (where national policies are based on such methods), and moreover the formation of a framework for developing a pan-Asian self-sustenance policy covering the stocking of basic food staples, will be briefly discussed.

Based on principals of economics, division of recycle processes is recommended among states and regions by their levels of economy and technology. Here is proposed an international collaborative framework which deals exploitation-distribution rights, exploitation taxes, customs, and so forth, to control trade and natural-resource exploitation to promote international recycle aiming at global reduction of wastes. An international organization levies the exploitation taxes. It redistributes them to financial aids for wharfage at trade of used articles and recycled-resource or to promotion of recycle industry in states yielding natural resources. Each state redistributes tariff to promotion of trade of used articles and recycled resources.

The liberalization and privatization of power sectors have been proceeding around the world since the 1990s, starting with Chile in 1982 and spreading to Asian Countries. Although some differences in degrees of liberalization and of privatization exist, the countries aim to reduce electricity tariffs and increase private investments by separation of generation, transmission, and distribution, introduction of competition, and efficient management of power utilities. However, it needs to be noted that framework of the power sector has shifted from “Development of the power sector anchored on the government guarantee” to “That of reasonable and fair risk sharing by each stakeholder”. Until now, in the Asian power markets, each country's public power utilities have guaranteed electricity purchase backed by the government's guarantee, eventually relieving electric power IPPs from investment risks in the market. However, the government's guarantee is going to be ceased due to financial difficulties of the government. In this sense, it is meaningful to study the experiences of Central and South America, where public utilities have already been privatized. Power business has already been operated with private investor's own risks.The lessons we could learn from experiences of the countries proceeded in power sector reforms in Europe, North, Central & South America are that the government should assume its responsibility in stabilizing the macro economy including exchange rate, and should design framework to facilitate competition among private investors in the area where market principle cannot be applied to, such in the field as transmission investment and rural electrification and prepare regulatory framework, including the reasonable transfer of price risks to end consumers, the reinforcement and gradual increase of electricity tariffs, grid code, market rules, establishment of supervisory organizations, setting up of incentives to facilitate investments in generation and transmission and so on.

Urbanization and population accumulation in Tokyo Metropolitan area, which has almost 30 million population, causing serious problems of heat island phenomenon and eutrophication in Tokyo bay. Possibility of deep ocean water is studied. Water of 200∼300m depth at the mouth of Tokyo bay may be suitable, as water temperature and nutrient concentration is relatively low there. Long pipeline of large diameter is necessary to transport ocean water. In the case study of 6 m diameter and 70km length pipe, 8% reduction of summer synthetic heat volume and 20% reduction of nutrient concentration in the inner part of Tokyo bay, may be expected. On the other hand, there are many problems of under sea tunnel construction technology, various impact to the environment, project revenue vs. huge construction cost etc..
