A scientific and historical study of crops and their age-old relationship with human civilization The cultivation and harvesting of crops have been at the heart of human culture and development for thousands of years. As we have grown from hunter-gatherers into agrarian societies and industrial economies, our ongoing relationship with the plants that feed us and support our manufacturing has also evolved. So too, of course, have those plants themselves, with the combined forces of shifting climates, selective plant breeding, and genetic modification all working to alter their existence in profound and fascinating ways. Coming some 30 years after its previous incarnation, the third edition of Harlan’s Crops and Man marks an exciting re-examination of this rich topic. Its chapters lay out the foundations of crop diversity as we know it, covering topics that range from taxonomy and domestication to the origins of agricultural practices and their possible futures. Highlights include: Archeological and anthropological studies of agriculture’s history and development Detailed examinations of the histories and classifications of both crops and weeds Explanations of taxonomic systems, gene pools, and plant evolution Studies of specific crops by geographical region Updated to include the latest data and research available, this new edition of Harlan’s Crops and Man offers an illuminating exploration of agricultural history to all those engaged with plant science and the cultivation of crops.

This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

In recent years, considerable progress has been made in the area of Nature-based Solutions (NbS) that improve ecosystem functions of environments and landscapes affected by agricultural practices and land degradation, while enhancing livelihoods and other social and cultural functions. This has opened up a portfolio of NbS options that offer a pragmatic way forward for simultaneously addressing conservation, climate and socioeconomic objectives while maintaining healthy and productive agricultural systems. NbS can mimic natural processes and build on land restoration and operational water-land management concepts that aim to simultaneously improve vegetation and water availability and quality, and raise agricultural productivity. NbS can involve conserving or rehabilitating natural ecosystems and/or the enhancement or the creation of natural processes in modified or artificial ecosystems. In agricultural landscapes, NbS can be applied for soil health, soil moisture, carbon mitigation (through soil and forestry), downstream water quality protections, biodiversity benefits as well as agricultural production and supply chains to achieve net-zero environmental impacts while achieving food and water security, and meet climate goals.
