The constant growth of the world's population and the decline of
the availability of land and soil resources are global concerns for
food security. Other concerns are the decrease in productivity and
delivery of essential ecosystems services because of the decline of
soil quality and health by a range of degradation processes. Key
soil properties like soil bulk density, organic carbon
concentration, plant available water capacity, infiltration rate,
air porosity at field moisture capacity, and nutrient reserves, are
crucial properties for soil functionality which refers to the
capacity of soil to perform numerous functions. These functions are
difficult to measure directly and are estimated through indices of
soil quality and soil health. Soil degradation, its extent and
severity, can also be estimated by assessing indices of soil
quality and health. "Geospatial Technology for Land Degradation
Assessment and Management" uses satellite imagery and remote
sensing technologies to measure landscape parameters and terrain
attributes. Remote sensing and geospatial technologies are
important tools in assessing the extent and the severity of land
and soil degradation, their temporal changes, and geospatial
distribution in a timely and cost-effective manner. The knowledge
presented in the book by Dr. R.S. Dwivedi shows how remote sensing
data can be utilized for inventorying, assessing, and monitoring
affected ecosystems and how this information can be integrated in
the models of different local settings. Through many land
degradations studies, land managers, researchers, and policymakers
will find practical applications of geospatial technologies and
future challenges. The information presented is also relevant to
advancing the Sustainable Development Goals of the United Nations
towards global food security.
