Book Description
Monitoring wetlands of Kenya is critical for analysis of environmental changes since they present unique ecosystems with special hydrological balance and biodiversity. In this study, the Landsat 8-9 OLI/TIRS satellite images for 2015-2022 were classified using GRASS GIS scripts to evaluate changes in the Lorian Swamp wetland, north-eastern Kenya. The results of the image analysis presented maps of land cover changes including wetlands. The study demonstrated technical effectiveness of the GRASS GIS for image analysis, and contributed to the environmental monitoring of African wetlands.

Book Description
This new book presents powerful techniques that can be used to address issues and problems related to wetlands and surface waters. It is the first book of its kind to address inventory and management of wetlands and water quality problems using GIS and remote sensing technologies. Wetland and Environmental Applications of GIS describes a variety of techniques, applications, and case studies for evaluating wetland and surface water characteristics at the landscape scale. The book details wetland and environmentally-oriented surface water resource studies using spatial and spectral based technologies such as GIS, remote sensing, computer modeling, and image display. Introductory material is included in the first section to provide a common background and to refresh or introduce concepts to the professional. The second section details applications of these technologies in studies of wetlands, including the use of GIS and archival satellite data in evaluating and measuring sediment types, water depth, and environmental change in the coastal wetlands of the Great Lakes. The third section addresses various environmental applications of GIS, such as locating non-point pollution sources and managing oil spills. The final section supplies additional information and applications, with particular emphasis on potential contributions of remote sensing.

Book Description
This book was written to assist scientists, engineers, technicians and other resource managers in the evaluation of wetland boundaries and characteristics. Powerful tools - GIS, mapping, remote sensing - are described and demonstrated using practical applications and combined to yield landscape ecological data, and ecological risk assessments. Using numerous technical methods, Wetland Landscape Characterization shows you how to evaluate the presence of wetlands, and the stressors, exposures and ecological systems - streams, lakes, terrestial - that influence their condition. A vital component of the book is the variety of quality assurance/quality control and accuracy assessment techniques presented throughout the text. A thorough understanding of these methods is critical to the success of your project.

Book Description
Over the last few years environmental management has been a major cause for concern especially in Africa. Kenya is not an exception in this issue with resources such as water, forests and wildlife being under threat from various quarters. The threat to water resources is posing a challenge to environmental sustainability. Lake Naivasha located in the Rift Valley in Kenya is one such water resource. There is a need to study such water resources and identify the problems facing them in order to suggest some solutions. This work takes a look at land use/ land cover changes with Lake Naivasha and its surroundings as the case study. It examines the use of Remote Sensing and Geographical Information Systems in mapping the land use/ land cover changes around the lake between 1986 and 2006 as well as predicting future changes and their implications. This book will be especially useful to professionals and students in the fields of environmental management and conservation, specifically those dealing with water resource management.

Book Description
This chapter begins with a synopsis of the basic concept of remote sensing with the various stages and interactions that characterize the entire remote sensing process described. A brief recapitulation of the status of stored water in Kenya is then presented. The monumental challenge facing many poor Kenyan households in accessing clean and safe water in sufficient quantities is reiterated. The chapter underscores the critical value of accurate and timely geospatial and hydro-meteorological datasets in supporting integrated water resources management. It is argued that the availability of techniques that deliver information on the changes in stored water at a more local scale is the first step towards realizing an efficient water society. Finally, two case studies that employ diverse remote sensing datasets to provide an evidence based explanation of the decline in stored water in Lakes Victoria and Naivasha are elucidated.

Book Description
The publication demonstrates the importance of using maps as an analytical and policy tool to examine the spatial distribution of poverty and ecosystem services in Kenya. Ecosystem services are the benefits people derive from ecosystems and include goods (food and water), services (flood and disease control), and nonmaterial benefits (spiritual and recreational benefits). A series of maps integrate poverty data from Kenya's most recent census with maps of regions in Kenya which are considered important for production of selected ecosystem services such as water (hydropower, access to drinking water, irrigation), food (crop and livestock), fuel, biodiversity, and tourism. The authors believe that users of Nature's Benefits: An Atlas of Ecosystems and Human Well-Being in Kenya will gain new insights on the spatial congruence of poverty and ecosystem services, improve targeting of programs addressing poverty and selected environmental services, and provide integrated datasets and methodologies for multi-scale use.
