Cooperation and communication among federal, state, and local stakeholders is required while balancing biophysical and socioeconomic concerns. The public is taking part in environmental decisions, and the need for technology transfer from public agencies to stakeholders is increasing. Information technology has had a profound influence on watershed management over the past decade. Advances in data acquisition through remote sensing, data utilization through geographic information systems (GIS), and data sharing through the Internet have provided watershed managers access to more information for management decisions. In the future, applications incorporating hydrologic simulation models, GIS, and decision support systems will be deployed through the Internet. In addition to challenges in making complex modelling technology available to diverse audiences, new information technology issues, such as inter-operability, Internet access, and security, are introduced when GIS, simulation models, and decision support systems are integrated in an Internet environment. Integrated watershed management requires a host of inter-related information to be generated and studied in relation to each other. Remote sensing technique provides valuable and up-to-date spatial, non-spatial, multi-layered information obtained in a wide variety of formats both from remote sensing and other conventional sources has proved to be an effective tool in planning for watershed development. Sustainable participatory watershed management is an approach to restore natural resources and agricultural productivity. The success of watershed management depends on multiple factors from the hydrological profile of the watershed to the local social and economy environment. (v) CONTENTS LIST OF CONTENTS PAGE NO. 1.

It requires cooperation with federal, state and local bodies while incorporating biophysical and socioeconomic process. Traditionally, transfer of information was unidirectional, typically from state of federal government agencies to landowners. In today's society, bidirectional communication is imperative, expanding the role of land management agencies in the decision making process. However, federal and state budgets are increasingly constrained and new techniques' for information transfer needs to be employed. Watershed management decisions are further complicated by both the complexity of the issues and those processes creating the problems. The difficulties in spatially representing and quantifying biophysical and socioeconomic process require that management decisions be based on imperfect information. Water is life, in all forms and shapes. This basic yet profound truth eluded many of us in the second half of the 20th century.
