The UN's Sustainable Development Goals saw the global community agree to end hunger and malnutrition in all its forms by 2030. However, the number of chronically undernourished people is increasing continuously. Ongoing climate change and the action needed to adapt to it are very likely to aggravate this situation by limiting agricultural land and water resources and changing environmental conditions for food production. Climate change and the actions it requires raise questions of justice, especially regarding food security. These key concerns of ethics and justice for food security due to climate change challenges are the focus of this book, which brings together work by scholars from a wide range of disciplines and a multitude of perspectives. These experts discuss the challenges to food security posed by mitigation, geoengineering, and adaptation measures that tackle the impacts of climate change. Others address the consequences of a changing climate for agriculture and food production and how the Covid-19 pandemic has affected food security and animal welfare.
