Water is an essential resource for all living beings, and soil is crucial in supporting life and acting as a reservoir for water. Plants rely on nutrients from water and soil resources, which are then consumed by animals, creating a delicate balance. Climate change has led to the degradation of water and soil quality, infectious diseases, water shortages, desertification, and erosion, and human pressure through overuse and pollution has accelerated these impacts. The Water-Soil-Plant-Animal nexus is a critical aspect of global food security and is heavily impacted by climate change. With the increasing concern about these impacts, scholars, decision-makers, and researchers are interested in understanding the interactions between these resources and climate change. Water-Soil-Plant-Animal Nexus in the Era of Climate Change explores relevant theoretical approaches, empirical research, and bibliometric and bibliographic methods to bring together affordable methods and techniques to optimize the use of the nexus in the context of climate change. The book's editor, Ahmed Karmaoui, brings nearly a decade of experience in biology into this project. This research presents an inventory of techniques and practices in the field and provides an opportunity to discuss the strengths and weaknesses of these techniques to support adaptation to climate change. This book is an essential resource for scholars, researchers, planners, and decision-makers who are interested in understanding the Water-Soil-Plant-Animal nexus and its impacts in the era of climate change.
