This book presents recent trends of nanotechnology in agroforestry systems to manage and reduce the fast degradation of natural resources in a sustainable manner. The book shows that nanocomposites profoundly improve seed quality, nutrition, growth, and stress resistance of crops and trees. However, the efficacy and ecotoxicity must be compared with the conventional agrochemicals. The book also discusses the complex interactions of nanoparticles in agroforestry ecosystems. It provides the understanding of the nanoparticle transformation process from laboratory to field conditions will help in technology transfer at a mass scale. Following the excellent contributions from global experts, the book will be very useful for students, scientists, conservationists, growers, and policymakers searching for the challenges and opportunities of nanotechnology in integrated farming systems.
