Remote Sensing of Global Croplands for Food Security

Emphasizing practical mapping technologies based on remote sensing, this book offers actionable approaches for estimating water use from irrigated and rain-fed croplands on a national, continental, or global basis. It offers case studies from a variety of continents highlighting the subtle requirements of each.

Written under the guidance of editors with strong backgrounds and experience, this book demonstrates methods and models for determining water resources used and resulting yields of irrigated and rain fed croplands. The book pulls together a comprehensive state-of-the art knowledge base on mapping areas using remote sensing. The text emphasizes practical methods and protocols for estimating water use from croplands and includes case studies from a variety of continents that highlight their own subtle requirements. Presenting advanced and practical technologies, the book provides actionable approaches for national, regional, continental, and global solutions.

! provides unique means for understanding and comparing different cropland mapping strategies by utilizing different satellite sensors and ancillary data sets. The chapters are well written for entry level through advanced level remote sensing or agricultural specialists, and each chapter can be read sequentially or separately. ! In summary, the ! thoroughly documents the techniques and error assessment methods utilized to develop the world's first global irrigated map derived from remote sensing data. ! the numerous international authors, color plates, and national cropland statistical tables makes the book an attractive and authoritative reference for mapping global croplands from remote sensing data. -- Curt A.
