Systematic planning for river rehabilitation: integrating multiple ecological and economic objectives in complex decisions

摘要: Owing to intensive human use, freshwaters are among the most seriously threatened and modified environments on planet. Their poor condition risk services that humans need from these ecosystems make their rehabilitation a priority. However, many previous studies have reported performance of activities. Here, we analyse reasons for this performance, focussing planning activities, propose new approach. We argue failure include driving factors at scale adequate capture ecological processes involved, together with an insufficient incorporation socio-economic aspects, is key factor leading approach, 'systematic planning', brings advances made in conservation (cost-effectiveness analysis) ecosystem science (understanding complexity processes). This enables be done catchment scale, trade-offs between various actions integrated prioritised. Finally, it important, given constraints imposed by lack knowledge, process part adaptive cycle where can benefit consolidate experience gained during implementation monitoring stages.
