Legumes are an important source of protein for humans and animals. They provide nutritionally rich crop residues for animal feed, and playa key role in maintaining the productivity of soils particularly through biological nitro gen fixation. They are, therefore, of immense value in rainfed farming systems. The International Center for Agricultural Research in the Dry Areas (ICARDA) has a responsibility for research on food, pasture, and forage legumes. The Center also has the broad objective of improving livestock production in rainfed farming systems. Although food legumes have be~n known and grown by farmers in the WANA region for a long time, their productivity has remained low and variable. Forage legumes, on the other hand, are not so well known by farmers of the region, and their role in the farming systems is not so well understood. Thus, we need to develop the concept of using forage legumes as crops and to fit them into cropping systems. In its efforts to increase the productivity of food legumes and develop the legume-based crop/livestock systems, ICARDA has established a network of scientists in the different National Agricultural Research Systems in the region. To further strengthen this network, ICARDA convened a workshop on 'The Role of Legumes in the Farming Systems of Mediterranean Areas' in Tunis, Tunisia, 20-24 June 1988. This workshop was co-sponsored by UNDP, who also contributed funds for this publication.

Genetic Resources of Mediterranean Pasture and Forage Legumes is a comprehensive review of grassland improvement in Mediterranean areas using legume species. The book includes a detailed account of the processes involved in understanding the ecology of legumes and their collection in the Mediterranean, through to their preliminary evaluation and storage at various Genetic Resource Centres. A generic conspectus and key to the forage legumes of the Mediterranean basin is also included. These proceedings are truly international with examples on the collection and use of Mediterranean genetic resources being illustrated by Genetic Resource Centres in Australia, Cyprus, France, Greece, Syria, Turkey and Tunisia. Current important issues such as the sustainability of Mediterranean grasslands, the risk of genetic erosion and the principles of population genetics employed during a collecting mission are discussed. The book will be of value to researchers working in the fields of grassland and rangeland improvement, Mediterranean farming systems, genetic resources, and pasture and forage ecology.

The world population will grow more rapidly during the few coming years. This must be accompanied by a parallel increase in the agricultural production to secure adequate food. Sustainability considerations mandate that alternatives to chemical nitrogen fertilizers must be urgently sought. Biological nitrogen (N2) fixation, a microbiological process which converts atmospheric N2 into a plant-usable form, offers this alternative. Among these renewable sources, N2-fixing legumes offer an economically attractive and ecologically sound means of reducing external inputs and improving internal resources. Environmental factors such as drought, elevated temperature, salinity, soil acidity and rising CO2 are known to dramatically affect the symbiotic process and thus play a part in determining the actual amount of nitrogen fixed by a given legume in the field. Understanding how nodule N2 fixation responds to the environment is crucial for improving legume production and maintaining sustainability in the context of global change. In this thoughtful and provocative new Brief, we provide critical information on how current and projected future changes in the environment will affect legume growth and their symbiotic N2 fixing capabilities. Each section reviews the main drivers of environmental change on the legume performance that include drought, elevated temperature, salinity and rising CO2, and soil acidity. Importantly we discuss the molecular approaches to the analysis of the stress response in legumes and the possible biotechnological strategies to overcome their detrimental effects.
