Recognized and advocated as a powerful tool, the role of remote sensing in identifying, mapping, and monitoring soil salinity and salinization will continue to expand. Remote Sensing of Soil Salinization: Impact on Land Management delineates how to combine science and geospatial technologies for smart environmental management. Choose the Right Techniques for the Job An overview of soil salinity assessment using remote sensing technologies, the book describes a variety of sensors, ranging from ground-based to airborne and satellite-borne, and their use in a diversity of geographical regions and environmental settings from coastal to inland saline areas. It provides guidance on how to identify and choose the right remote sensing tools and data sets required based on the purpose of the study and the environmental setting. Organized into three sections, the book covers: Section I: Soil Salinity and Remote Sensing: The Object and the Tool — Focuses on the relationships between the landscape-object salinity and the remote sensing tools Section II: Trends in Mapping Soil Salinity and Monitoring Salinization Using Remote and Proximal Sensing — Provides a variety of case studies dealing with soil salinity mapping and monitoring the process of salinization Section III: Diversity of Approaches to Modeling Soil Salinity and Salinization — Demonstrates the diversity of approaches used in modeling soil salinity and salinization in space and time Combines Fundamentals, the Latest Technology, and Practical Examples The book includes analyses of basic issues of remote detection, such as the spectral behavior of salt types and vegetation influence, and evaluations of currently available remote sensing platforms delineating their advantages and disadvantages. The accompanying CD-ROM provides color images that enhance the material discussed in the text. The mixture of fundamental concepts, latest technological reviews, and practical application examples makes this an ideal resource for environmental assessment and decision making.

The land degradation due to salinity and waterlogging is a global phenomenon, afflicting about one billion hectares within the sovereign borders of at least 75 countries. Besides staring at the food security, it has far reaching and unacceptable socio-economic consequences since a large proportion of this land is inhabited by smallholder farmers. The anthropogenic-environmental changes and the climate change are further adding to the problem of salinity and waterlogging. The phenomenon of sea-level rise will bring more areas under waterlogged salinity due to inundation by sea water. Thus, dealing with the salinity in reality is becoming a highly onerous task owing to its complex nature, uncertainty and differential temporal and spatial impacts. Nevertheless, with the need to provide more food, feed, fuel, fodder and fiber to the expanding population, and non-availability of new productive land, there is a need for productivity enhancement of these lands. In fact, the salt-affected and waterlogged lands cannot be neglected since huge investments have been made throughout the world in the development of irrigation and drainage infrastructure. The social, economic and environmental costs being high for theon-and/off-farm reclamation techniques, saline agriculture including agroforestry inculcated with modern innovative techniques, is now emerging as a potential tool not only for arresting salinity and waterlogging but for other environmental services like mitigate climate change, sequester carbon and biodiversity restoration. This publication attempts to address a wide range of issues, principles and practices related to the salinity involved in rehabilitation of waterlogged saline soils and judicious use of saline waters including sea water. Many of the site specific case studies typical to the saline environment including coastal ecologies sustaining productivity, rendering environmental services, conserving biodiversity and mitigating climate change have been described in detail. Written by leading researchers and experts of their own fields, the book is a must, not only for salinity experts but also for policy makers, environmentalists, students and educationists alike. More importantly, it contributes to reversing the salinity trends and teaches to sustain with salinity ensuring the livelihood of resource-poor farming families leaving in harsh ecologies including coastal areas which are more vulnerable to climate change.

Best Management Practices for Saline and Sodic Turfgrass Soils

The complex issues involved in the management of saline and sodic turfgrass soils are enough to perplex even the most experienced site manager — there is no "silver bullet" amendment, treatment, or grass for salinity management. Best Management Practices for Saline and Sodic Turfgrass Soils: Assessment and Reclamation presents comprehensive scientific principles and detailed, practical management and assessment recommendations for turfgrass and landscape sites. The authors use the Best Management Practices (BMPs) concept, considered the gold-standard management approach for any individual environmental issue, since it is a whole ecosystem (holistic), science-based salinity management approach that allows all possible management options to be considered and implemented on a site-specific basis. They identify BMP strategies, including irrigation system design; irrigation scheduling and salinity leaching; chemical, physical, and biological amendments; cultivation; topdressing; soil modification; sand-capping; surface and subsurface drainage options; nutritional practices; additional cultural practices; and ongoing monitoring. The book presents emerging challenges, technology, and concepts that address integration of salinity management into comprehensive site environmental or sustainable management systems, use of halophytic turfgrasses for non-traditional purposes, integration of geospatial and geostatistical concepts and technology, and integration of new sensor technology into daily management paradigms. Outlining a holistic BMP approach, the book incorporates scientific principles and practical management recommendations and details specific salinity challenges and the logic behind each BMP strategy for salinity management, with an emphasis on actual field problems. The book is formatted for flexible use, with stand-alone chapters that include outlines for quick review of a topic for those requiring only a basic understanding as well as in-depth discussions of the science and practical aspects for those seeking a more rigorous treatment. It supplies a single source for all the information required to identify and manage diverse types of salinity stresses.

In this study, satellite remote sensing and geographic information system (GIS) techniques were used to analyze the agricultural performance and sustainability of the Bhakra Irrigation System in India. The results demonstrate the synergy possible from applying satellite remote sensing and GIS to evaluate trends in rising water tables and salinity, which are two important threats to the sustainability of irrigation systems, and the cost-effectiveness of these techniques as diagnostic tools for irrigation system improvement.

This edited volume is based on the best papers accepted for presentation during the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. The book compiles a wide range of topics addressing various issues by experienced researchers mainly from research institutes in the Mediterranean, MENA region, North America and Asia. Remote sensing observations can close gaps in information scarcity by complementing ground-based sparse data. Spatial, spectral, temporal and radiometric characteristics of satellites sensors are most suitable for features identification. The local to global nature and broad spatial scale of remote sensing with the wide range of spectral coverage are essential characteristics, which make satellites an ideal platform for mapping, observation, monitoring, assessing and providing necessary mitigation measures and control for different related Earth's systems processes. Main topics in this book include: Geo-informatics Applications, Land Use / Land Cover Mapping and Change Detection, Emerging Remote Sensing Applications, Rock Formations / Soil Lithology Mapping, Vegetation Mapping Impact and Assessment, Natural Hazards Mapping and Assessment, Ground Water Mapping and Assessment, Coastal Management of Marine Environment and Atmospheric Sensing.
