One Planet, One Health provides a multidisciplinary reflection on the state of our planet, human and animal health, as well as the critical effects of climate change on the environment and on people. Climate change is already affecting many poor communities and traditional aid programs have achieved relatively small gains. Going beyond the narrow disciplinary lens and an exclusive focus on human health, a planetary health approach puts the ecosystem at the centre. The contributors to One Planet, One Health argue that maintaining and restoring ecosystem resilience should be a core priority, carried out in partnership with local communities. One Planet, One Health offers an integrated approach to improving the health of the planet and its inhabitants. With chapters on ethics, research and governance, as well as case studies of government and international aid-agency responses to illustrate successes and failures, the book aims to help scholars, governments and non-governmental organisations understand the benefits of focusing on the interdependence of human and animal health, food, water security and land care.
