The role of livestock and livestock diversity in sustainable diets
Sustainability is a complex and sometimes contested concept. While the overall concept is widely accepted and used, a clear definition is still problematic as different stakeholders – and stakeholders at different levels – have different interpretations. The Johannesburg Declaration on Sustainable Development states that there are three fundamental ‘pillars’ to sustainable development: environmental protection, economic growth and social equity, both in an interand intra-generational equity perspective. However, the ‘three-pillars’ model is imperfect because it is based on the assumption that trade-offs can be made between the environmental, social and economic dimensions of sustainability.
