While sustainability is generally seen as the work of government (policymakers) and technologists (scientists or engineers), and thus a top-down endeavor in which citizens or communities are seen as "adopters" (as in, how can we get people to retrofit their homes? or turn off their lights when they don't need them?), the field is slowly starting to recognize the key role that people and communities need to play, not only as trusted messengers in getting people to engage in sustainability and climate actions, but also in deliberating about the challenges and creating new innovative, community- and culturally-based solutions. Within sustainability studies and in practice, there are increasingly theories and examples of participatory processes that lead to new types of sustainability practices. When these processes involve collaborations between communities and government, they are known as "collaborative governance."
