What is regenerative agriculture? Although this concept is frequently used in discussions about food systems transformation, and is starting to attract the attention of corporates and the mainstream, it lacks a formal definition, and what counts as "regenerative" can vary based on the individual asked, or the context. In this explainer, we explore ways of thinking about regenerative agriculture in relation to its various definitions, the stakeholders using the term, its knowledge practices and knowledge base, and how it fits in with wider goals for food system change.

Should we eat meat, eggs, dairy and other animal-sourced foods? If so, how should we produce them and how much should we eat? If not, what should we eat instead? These are just some of the more contentious debates about the future of food systems. This short briefing paper summarises some of the key debates about livestock and its alternatives and describes both the arguments and the evidence underpinning different points of view. We look both at foodstuffs (meat, fish, plants and new foods based on cells grown in bioreactors) and farming methods (both intensive and extensive) with regards to discussions about their environmental, health and social impacts. In so doing, we explore the assumptions and values that often lead stakeholders to differing conclusions about what a sustainable food system looks like.
