The most important problem is the population explosion. The population of 2.8 billion around 1945 doubled during the following 50 years, and it will approximately double again, reach- ing 10 billion during the next 50 years. This population increase will produce serious effects on worldwide food consumption and distribution; however, a sharp production increase in agricultural products cannot be expected. During the next 50 years, all presently known deposits of natural gas and petroleum and those to be mined in the future will have been exhausted. This shortage of fossil fuel will seriously affect agricultural activities. Present agricultural practices cause environmental problems. Most peo- ple believe that agriculture is gentle to nature and the earth, as the green of agricultural fields comforts the human mind. However, the same green harms the earth. For example, CO 2 from agroecosystems is a greenhouse- effect gas and nitrogen fertilizer in runoff water from fields may cause eutrophication of lakes and rivers. These problems are discussed in the chap- ters that follow. In this book, biological interactions, matter circulation, and disturbances operating within the agroecosystems in question will be discussed by 31 sci- entists working in the fields of agricultural science and applied ecology. A major purpose of this book is to clarify the structure and function of individ- ual agroecosystems. Although this book does not attempt to give the entire picture of these agroecosystems, the authors stress the importance of studies to elucidate agroecosystems structure and function. These studies will make it possible to develop alternative types of agriculture in the twenty-first cen- tury. The authors live in different parts of the world: China, the Czech Republic, Finland, Greece, India, Italy, Japan, New Zealand, the U.K., and the U.S. We hope that such a wide range of experiences contribute to a world- wide ecdysis of present agriculture and to improvements of other types of agriculture. If this book can stimulate researchers and students in the fields of agroecology and agronomy in the world, our major objective will have been fulfilled. We express sincere gratitude to the contributors of the 19 chapters and to Professor Clive A. Edwards, The Ohio State University, for giving us an opportunity to write and edit this important book. Masae Shiyomi Hiroshi Koizumi 920103_CRC20_0904_FM 1/13/01 11:30 AM Page v 920103_CRC20_0904_FM 1/13/01 11:30 AM Page vi Editors Masae Shiyomi is a professor of the Faculty of Science at Ibaraki University, Mito, Japan. He is president of the Japanese Society of Grassland Science and the Japanese Agricultural Systems Society until 2001. He is a leader in grass- land science. He and his students are studying energy and matter flow and the modeling of grassland ecosystems. He is also an applied statistician, and his ecological work has been deeply enhanced due to his expertise in statistics. Professor Shiyomi was born in 1938 in Kyoto Prefecture. He graduated from the University of Tokyo, Faculty of Agriculture in 1961 and received the degree of Doctor of Agriculture from the University of Tokyo in 1980 with the thesis: “Mathematical ecology of spatial patterns of biological populations”; he also received the degree of Doctor of Science from Ibaraki University in 2000, based on his study titled “Spatial pattern of grassland vegetation— models and methods.” From 1961 to 1978, he worked at the Statistical Division, the former National Institute of Agricultural Sciences, and the Ministry of Agriculture, Forestry and Fisheries in Japan. In 1978 he moved to the Ecology Department of the National Grassland Research Institute and Plant Ecology Division of the National Institute of Agro-Environmental Science in the same ministry and continued working there until 1994. In 1994, he obtained his present position at Ibaraki University. Professor Shiyomi has obtained various prizes: the Prize of the Japanese Society of Grassland Science, the Prize of the Minister of Agriculture, Forestry and Fisheries, the Japan Prize of Agriculture, and the Agriculture Prize of the Yomiuri Newspaper Company for his studies of systems analy- sis and statistical ecology in agriculture. He received the title of Honorary Professor at the Northeast Agricultural University, Harbin, China. He has written many books and scientific papers. His hobbies include writing Japanese-style poems and making Japanese-style flower arrangements. Hiroshi Koizumi is a professor of the Institute for Basin Ecosystem Studies at Gifu University, Gifu, Japan. He completed his undergraduate and gradu- ate education at the Department of Biology at Waseda University in Tokyo, receiving a M.S. degree in 1972 and Doctor of Science degree in 1986 with the thesis: “The life history of Pylora japonica populations and their light condi- tions.” As a research assistant he worked for approximately 3 years at the Institute of Biological Sciences, University of Tsukuba, Japan. Thereafter he moved to the Plant Ecology Laboratory at the National Institute of Agro- Environmental Sciences, Ministry of Agriculture, Forestry and Fisheries, Japan. In 1992 and 1993 he worked at the Crop Science Section of the Agricultural Research Centre of Finland to conduct cooperative research between Japan and Finland. In 1998 he obtained his present position at Gifu University. Professor Koizumi’s research activities have focused on the ecological physiology of forest floor plant species. He has been particularly interested in the light environment and carbon gain of understory herbs associated with 920103_CRC20_0904_FM 1/13/01 11:30 AM Page vii sunflecks in a forest. He has also been interested in primary productivity and the efficiency of solar energy utilization in several cropping systems. More recently, he has extended his research interests to environmental problems and sustainable land use. He is now focusing on carbon dynamics, budgets, and sequestrations in agricultural and forest ecosystems. 920103_CRC20_0904_FM 1/13/01 11:30 AM Page viii Contributors Hiroshi Amano Faculty of Horticulture Chiba University Matsudo, Japan amano@midori.h.chiba-u.ac.jp Zuozhong Chen Institute of Botany Chinese Academy of Sciences Beijing, People’s Republic of China CHENZZ@botany.ihep.ac.cn Harry Clark AgResearch Grasslands Palmerston North, New Zealand harry.clark@agresearch.co.nz James E.
