ICARDA has the serious and urgent responsibility for increasing the quantity and availability of food in the extensive North Africa-West Asia region, and therefore must give high priority to optimising the use of soil water and nitrogen which are considered to be among the main limiting factors to production. To obtain the knowledge to further this aim, and with the help of the United Nations Development Program (UNDP), ICARDA is developing a special project on 'Increasing the Fixation of Soil Nitrogen and the Efficiency of Soil Water Use in Rainfed Agricultural Systems in the Countries of North Africa and Western Asia'. In planning this project, ICARDA has called on the expertise of leading scientists in a number of countries who can give the benefit of their experience, and advise on methods and priorities on which this specific research can be soundly based and conducted. To provide a forum for the presentation and exchange of such information, ICARDA, with the help of UNDP, invited a number of these scientists to a week-lung workshop at Aleppo in January 1980. This workshop gave rise to valuable discussions which culminated in several recommendations by which the project will be guided. The organising committee comprised Drs. J. Begg (Aus tralia), P. Cooper and D. Gibbon (lCARDA), P. Dart (Australia), G. J. Koop man and J. McWilliam (ICARDA Board of Trustees), A. Kassam (England) and P. Vlek (U.S.A.)."

"Principles of Environmental Physics: Plants, Animals, and the Atmosphere, 4e, "provides a basis for understanding the complex physical interactions of plants and animals with their natural environment. It is the essential reference to provide environmental and ecological scientists and researchers with the physical principles, analytic tools, and data analysis methods they need to solve problems. This book describes the principles by which radiative energy reaches the earth s surface and reviews the latest knowledge concerning the surface radiation budget. The processes of radiation, convection, conduction, evaporation, and carbon dioxide exchange are analyzed. Many applications of environmental physics principles are reviewed, including the roles of surface albedo and atmospheric aerosols in modifying microclimate and climate, remote sensing of vegetation properties, wind forces on trees and crops, dispersion of pathogens and aerosols, controls of evaporation from vegetation and soil (including implications of changing weather and climate), and interpretation of micrometeorological measurements of carbon dioxide and other trace gas fluxes.
Presents a unique synthesis of micrometeorology and ecology in its widest senseDeals quantitatively with the impact of weather on living systems but also with the interactions between organisms and the atmosphere that are a central feature of life on earthOffers numerous worked examples and problems with solutionsProvides many examples of laboratory and field measurements and their interpretationIncludes an up-to-date bibliography and review of recent micrometeorological applications in forestry, ecology, hydrology, and agriculture"
