This valuable book, the third volume in the Research Advances in Sustainable Micro Irrigation series, focuses on sustainable micro irrigation management for trees and vines. It covers the principles as well as recent advances and applications of micro irrigation techniques. Specialists throughout the world share their expertise on: • Automation of micro irrigation systems • Service and maintenance of micro irrigation systems • Evaluation of micro irrigation systems • Scheduling of irrigation • Using municipal wastewater for micro irrigation • Micro-jet irrigation and other systems • The effect of potassium, acid lime, and other elements

Planning for the use of rural lands in the developed countries of the world has become an increasingly contentious process as resources become more limited and conflicting needs grow stronger. The critical questions are "Which is more important—agriculture, livestock production, recreation, industry, or urban housing?" and "Who decides priorities and responsibilities for use?" The capacity of the land to meet all of the demands placed upon it, without serious environmental disruption, has become a major concern for all. Recognizing the exigencies of the situation, the contributors define and evaluate the theoretical and methodological frameworks within which rural land-use problems can be analyzed. In , the discussions focus on the identification and characterization of resources and competing users of rural lands, stressing that a careful articulation of the problem is essential to effective planning. is aimed at developing appropriate information bases useful in planning for the problems related to the management of these rural lands. The discussion of policy options for rural resource use in builds upon the material in the previous two sections to provide a framework for an analysis of rural resource use.
