Exploring the strategic environmental assessment (SEA) process behaviour using sensitivity analysis

This paper reflects on the results from a study that set out to model the behaviour of the strategic environmental assessment (SEA) process as it delivers environmental integration. It applied sensitivity analysis to the English SEA system, whilst viewing the SEA process as composed of a complex interaction of individual elements; through 'inputs and outputs' underpinned by negative and positive feedback loops that self-regulate the achievement of environmental integration. The study revealed at least five behavioural characteristics at the level of individual elements based on their relative dominance and consequent influence in process activities. At systemic process level, at least three key behavioural tendencies were identified. Overall, the process was poor in self-regulation, hampered by a lack of adequate feedback mechanisms. No single element or group of elements was critical in shaping process response and self-regulation towards delivering a consistent level of environmental integration.
