These tensions must be addressed if we are to develop combinations of human and ecosystem wellbeing that will eventually prove to be sustainable. No one knows what these combinations of wellbeing are or how to achieve them. Progress depends on recognizing our ignorance and uncertainty, and founding our actions on questions and learning through groups of people reflecting and acting in their communities. What we mean by assessment We consider diagnosis, monitoring and evaluation to be the three components of assessment. Action and reflection is a continuous cycle in which action is consciously seen as an instrument of reflection each action is an experiment.
Diagnosis explains why the action is necessary.
Monitoring follows its progress. Evaluation draws conclusions about both progress and the outcome. Regardless of the goal, assessment is needed to achieve it. Action and reflection are part of a cycle in which assessment guides action and action informs assessment. Assessment enables people to define what they mean by sustainable development, to articulate sustainable development objectives, and to track their progress in achieving those objectives.
