Book Description
... we do not yet seem to have realised that the exchange of products between countries in one part of the world but at different stages of development is no less natural, and no less profitable for the various nations, than the exchange of products which differ because they grow in different climates' (Thiinen-Hall, xg66, p. 194). There have been few attempts to study agriculture within a spatial framework, notwithstanding the quintessential importance of land as a production factor. Land is most often treated as generalized environment although it could also be considered as social and economic space-social because even the most crowded of farming communities has much greater distance between its basic social units than exist within an urban-industrial agglomeration, and economic because distances to markets, to factor sources and to information must be overcome and frequently vary by type of market, factor and information source. Modem agricultural geography has been largely preoccupied with the development of techniques and with classification, often as ends in thexnselves, or with a geographical element consisting mainly of some general locational reference or regional description. Rarely has there been an attempt to identify a spatial structure associated with some particular agricultural enterprise* or practice.

Book Description
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.

Book Description
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.
