Book Description
The Global Agro-Ecological Zoning version 4 (GAEZ v4), launched on June 17th 2021, uses well-established land evaluation principles to assess natural resources for finding suitable agricultural land utilization options. It is based on agro-climatic assessments, models, natural and human resources, crop statistics and water use at global scale. With the increasing complexity and intensity of environmental and social challenges an improved understanding of the physical drivers of climate change is necessary. Consequently, a systematic and harmonized update of the global datasets is intended for the further development of GAEZ. The main strategic goal of new version of GAEZ (version 5) is to make the outputs of the system available to national entities to support wise land use decision-making. To this end, supported by the GAEZ Partnership, GAEZ v5 will provide dynamically updated AEZ information, to meet local to global level AEZ users’ need. To refine the overall GAEZ assessment, additional layers will be included in the land resources and climate database. Appendix 1 “Recommendations for further GAEZ development”) of the GAEZ v4 Model Documentation1 provides a list of potential database updates and improvements including for climate (both base-line and climate projections), land cover/land use, soil (with improved detail of processes such as land degradation) and ancillary datasets used for reporting and planning (e.g. areas reserved for environmental protection and maintenance of biodiversity, population density, livestock, administrative boundaries) GAEZ makes use of best available global spatial databases to estimate the biophysical crop production potential for over 100 crops and crop sub-types. The estimation procedures consecutively consider factors relevant for crop production over time and for different management conditions. An overview of the overall GAEZ v4 model structure and data integration is shown in Figure 1 and detailed information about the process and methodology are provided in the Model Documentation.

Book Description
Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration. An accurate estimation of carbon stocks and an understanding of the carbon sources and sinks can aid the improvement and accuracy of carbon flux models, an important pre-requisite of climate change impact projections. Based on 15 research topics, this book demonstrates the role of remote sensing in quantifying above ground biomass (forest, grass, woodlands) across varying spatial and temporal scales. The innovative application areas of the book include algorithm development and implementation, accuracy assessment, scaling issues (local–regional–global biomass mapping), and the integration of microwaves (i.e. LiDAR), along with optical sensors, forest biomass mapping, rangeland productivity and abundance (grass biomass, density, cover), bush encroachment biomass, and seasonal and long-term biomass monitoring.

Book Description
Global change is posing new threats to agroecosystems. First, climate modifications in the spatial and temporal distribution of rainfall increase the risks of severe droughts during the growing season of most crops. Second, conventional agriculture has led to the extension of mono-crop fields that decreased biodiversity in agroecosystems; it is possible that these fields will lack resilience when faced with changing climate. In addition, a new conscience has arisen and consumers tend to look for healthy products that, sometimes, do not match the objectives of conventional agriculture. In this context, sustainable and environmentally friendly agricultural practices that can cope with the new global change scenario are needed. This eBook compiles state-of-the-art research on the agroecosystems response to global change and on how to manage these new scenarios. Despite the broad scope of the topic, this Research Topic covers a wide range of subjects, including biodiversity, crop performance, novel agricultural practices and soil properties.

Book Description
This book examines global environmental governance and how legal, institutional, and conceptual reform can facilitate a transformation to a new ‘natural-systems’ form of agriculture. Profound global climate disruption makes it essential that we replace our current agricultural system – described in this book as a fossil-carbon-dependent ‘modern extractive agriculture’ – with a natural-systems agriculture featuring perennial grains growing in polycultures, thereby mimicking the natural grassland and forest ecosystems that modern extractive agriculture has largely destroyed. After examining relevant international legal and conceptual foundations (sovereignty, federalism, global governance) and existing international organizations focusing on agriculture, the book explores legal and institutional opportunities to facilitate dramatic agricultural reform and ecological restoration. Among other things, it explains how innovative federalism structures around the world provide patterns for reorienting global environmental governance, including what the book calls eco-states that would, through exercise of pluralistic sovereignty, be responsible for agroecological management. Drawing from his experience working in international institutions, the author provides detailed global-governance proposals for facilitating the type of agricultural reform that can help avoid ecological collapse, especially through soil degradation and climate change. This book will be of great interest to students and scholars of international law, agroecology, climate change, ecological restoration, sustainable development, and global governance, as well as policy-makers and practitioners working in these fields.

Book Description
This book focuses on the status quo and the latest information on the water-soil-agriculture nexus in the MENA countries. It presents several case studies and applications from e.g. Morocco, Algeria, Tunisia, Egypt and Jordan, while also sharing and discussing the latest findings. The content includes a range of agriculture-related topics that focus on: water resources management, impacts of climate change, and wastewater treatment for reuse in agriculture sectors; in addition, sustainable approaches to agricultural-based industry, organic crop production, crop water requirements, and soil environment are discussed in an updated and comprehensive review. In turn, the book discusses the applications of GIS and remote sensing as a new technology for better agriculture management, as well as its use in Egypt as a representative country. In closing, it considers the implementation of an environmental information system in data-scarce MENA countries from the standpoint of the water-food nexus, and addresses the question of climate justice in the MENA region. Exploring various dimensions of MENA country-based case studies on achieving sustainable agriculture, the book offers an invaluable source of topical information for agricultural sustainability-related stakeholders in the region, researchers and graduate students alike.

Book Description
The Second Edition of this book is completely revised and updated throughout providing an overview of current challenges faced within the area of Agri-food in relation to policymaking, ecological conservation and socio-environmental justice. Including a range of new chapters, the book explores some of the conceptual and analytical gaps that are presented by current approaches to this topic. The series of interconnected chapters offers a critical reinterpretation of the tensions associated with the failures of mainstream regulatory regimes, land and resource grabbing, and the impacts of global agri-food chains at local, regional and inter-sectoral scales. The book also examines past legacies and emerging challenges associated with agriculture modernisation, politico-spatial disputes, climate change, social movements, gender, ethnicity and education. It likewise addresses the transformative potential of different combinations of biophysical, socio-technical and socio-spatial practices of food sovereignty.
