Sustainable sustainability

Something is sustainable when it can continue into the future, coping with and recovering from stresses and shocks, while not undermining the resources on which it draws for existence. These resources may be natural, social, economic or institutional, which is why sustainability is often analyzed in four dimensions: economic sustainability, environmental sustainability, institutional sustainability and social sustainability. Sustainability does not imply that there is no change, but that there is an ability to adapt over time. Sustainability is one of the core principles of the sustainable livelihoods approach.
