There is a rapid transformation afoot in the rice value chain in Asia. The upstream is changing quickly-farmers are undertaking capital-led intensification and participating in burgeoning markets for land rental, fertilizer and pesticides, irrigation water, and seed, and shifting from subsistence to small commercialized farms; in some areas landholdings are concentrating. Midstream, in wholesale and milling, there is a quiet revolution underway, with thousands of entrepreneurs investing in equipment, increasing scale, diversifying into higher quality, and the segments are undergoing consolidation and vertical coordination and integration. Mills, especially in China, are packaging and branding, and building agent networks in wholesale markets, and large mills are building direct relationships with supermarkets. The downstream retail segment is undergoing a 'supermarket revolution,' again with the lead in change in China. In most cases the government is not playing a direct role in the market, but enabling this transformation through infrastructural investment. The transformation appears to be improving food security for cities by reducing margins, offering lower consumer rice prices, and increasing quality and diversity of rice. This paper discusses findings derived from unique stacked surveys of all value chain segments in seven zones, more and less developed, around Bangladesh, China, India, and Vietnam.

There are major challenges facing the countries in the Pacific Basin. These include issues of hazardous waste management and the consequent adverse effects of hazardous wastes on human health, the potential disruption of our whole way of life as a consequence of global climate change, and the increasing problem on human health of air pollution and the effects of breathing polluted air. These issues and others were the focus of the 12th meeting of the Pacific Basin Consortium for Environment and Health Sciences, held in Beijing in late 2007. This volume is a collection of papers presented at that meeting, and this introductory chapter provides some perspective on three of the major issues that are of concern in all of the countries in this region. This meeting provided an opportunity for Chinese scientists and those from other countries in the Pacific Basin to share perspectives and possible solutions with others from the international community, and these various approaches are reflected in these proceedings.
