This chapter discusses the complex notion of sustainability that has become a key frame for confronting the challenges of climate change, resource depletion, and social inequality. Sustainability is thus a matter of being able to meet certain needs now without preventing our children from being able to do the same. This definition has transformed now including a holistic view of environmental sustainability, economic viability, and social equity. This chapter outlines the trajectory of sustainability from early environmental accountabilities to important milestones, including the 1972 United Nations Conference on the Human Environment, the 1992 Earth Summit, and the adoption of the Sustainable Development Goals (SDGs) in 2015. These occurrences reflect the growing awareness of the interrelatedness of various systems in regard to social, economic, and ecological, with sustainable development presented as a multidimensional concept aimed at improving the quality of human life and safeguarding the natural environment (UNESCO, 2023). As the world faces new global challenges, such as biodiversity loss and climate change, this chapter highlights the need for sustainable practices to build resilience and adaptability, in both policy and society. It highlights the need to implement sustainability frameworks that can push back against the negative impacts of unsustainable patterns of growth and set out the pathways for a healthier interdependence with natural systems. This effort to synthesize the many different manifestations into a conceptual framework is intended to help inform policymakers and practitioners about how best to incorporate sustainable practices into their own operations and, in doing so, help guide humanity toward a sustainable future.
