The book focuses on the Abbay Basin biophysical setting, the status of natural resources and degradation processes, agricultural practices, environmental resource conservation efforts, and the role of Earth observation and geospatial technologies in monitoring and planning for the wise utilization of natural resources under severe land resource degradation and climate change. It provides a collection of techniques and syntheses from the perspectives of geospatial science and technology application dimensions as well as legal and sociopolitical circumstances. It utilizes comprehensive data, algorithms, methods, and tools to produce and disseminate high-quality information for the Abbay Basin. It also produces empirical data and knowledge on what has been done thus far regarding the application of EO data and geospatial technologies for sustainable utilization of natural resources in the Abbay Basin and synthesizes previous studies to develop strong and consolidated information on the basin. The book will also have distinct outlooks on the purpose and contribution of satellite imagery and geospatial data as well as improved analytics for basin-wide resource management.

The book is a thorough presentation of theoretical and applied aspects of the evaporation and evapotranspiration process supported by data from experimental studies. It is written in a way that the theoretical background of evaporation and evapotranspiration estimation is presented in a simplified manner, comprehensive to most technical readers. The book deals with details of meteorological parameters and monitoring sensors which are needed for estimating evaporation and evapotranspiration. Errors in meteorological parameter measurements are also presented. Estimation errors, strengths, weaknesses and applicability of a wide range of evaporation and evapotranspiration estimation methods are presented along with samples of application to a certain region. Application of newer simpler methods is presented. A new technology, remote sensing application to evaporation and evapotranspiration estimation, is presented. The latest interest in the subject, climate change and evapotranspiration is presented in the last chapter. This book will be beneficial to students, hydrologists, engineers, meteorologists, water managers and others.
