International concern over the threat to species and ecosystems caused by human activities is at an all time high, which may result in high costs to present and future generations. The economic costs and benefits associated with the conservation and sustainable use of genetic resources of actual or potential value for food and agriculture is largely unknown. Economic instruments that can encourage implementation of socially optimal genetic resource conservation strategies as well as the sharing of the real benefits and costs are a useful measurement tool. This book is an edited compilation of papers from the Symposium on the Economics of Valuation and Conservation of Genetic Resources for Agriculture held in Rome in May 1996. It addresses some of the key issues involved in the estimation of the economic value of conserving genetic resources for agriculture. It covers the modelling of the value of Plant Genetic Resources (PGRs), empirical studies of PGRs (including field diversity and yield vulnerability), seven empirical studies of PGR breeding values, property rights in PGRs and the implications of modern biotechnology methods for PGR values. The book will be essential reading for workers in agricultural economics, plant breeding and genetics, and biodiversity and conservation.

Rice has supported a greater number of people for a longer period of time than any other crop. Nearly half of the global population is dependent on rice as its major staple food. While Asia remains the main centre of production and consumption of rice, the importance of rice is increasing rapidly in Africa and Latin America, and exports of rice from the United States and Australia are of major importance to the world rice trade. This book explores the factors which have contributed to the sustainability of rice production over the eight or nine thousand years for which rice has been produced. Sustainability is defined as the maintenance or improvement of production levels and protection of natural resources, within the context of economic viability and social acceptability. The author covers a wide range of issues, including soil fertility, plant breeding, pest management, irrigation, land degradation and social and economic factors. Greatest emphasis is placed on the special features of wetland rice production, and the importance of the nutrient balance. It is also shown that without the Green Revolution there would have been a period of mass starvation in Asia, a problem which continues to threaten and which will be unavoidable unless the successes of the Green Revolution can be sustained. The book provides a unique review of the sustainability of the production of the world's most important crop, and should be of interest to students, research workers and policy makers in agriculture, soil science, and agricultural economics and food policies, as well as all interested in development in the third world.

The book by M. Imran Kozgar aims to cover the problems of mutation breeding in pulse crops in the light of issues related to food insecurity and malnutrition, which according to FAO are the major threats at the present time. So far the research on induction of mutation in pulse crops is negligible compared to cereal crops, though the pulse crops and especially the chickpea are the largest grown crops in India. The main objective of the book is to reveal and explore the possibility of inducing genetic variability in early generations of mutated chickpea, describe the positive aspects of mutagenic treatments, evaluate the content of mineral elements (iron, manganese, zinc and copper) and physiological parameters of isolated high yielding mutant lines. The author hopes that his book will help to advance studies on pulse crops, and that in the long term it will help to reduce the food insecurity and malnutrition problems presently persisting in various developing countries, including India.
