This book lays the groundwork for understanding the economic and strategic aspects of animal health investments, setting the stage for a global shift towards sustainable veterinary infrastructure. Illuminating the practical implications of adopting system-based approaches to animal health financing, it scrutinizes case studies and success stories where integrated financial strategies have led to improved veterinary services and, consequently, better health outcomes for both animals and humans.The volume advocates for: the adoption of financing mechanisms that are not only sustainable but also adaptable to the challenges posed by climate change, biodiversity loss, and the emergence of zoonotic diseases; a shift towards financing that supports robust veterinary infrastructure and proactive health measures; considering global discourse on the most effective ways to mobilize resources for the collective benefit of all species and the planet. Part of a wider series that provides a blend of technical insight, strategic analysis, and practical approaches to enhancing animal health, this book is a first step to achieving poverty reduction and improved human welfare.
