Setting conservation priorities in cities: approaches, targets and planning units adapted to wetland biodiversity and ecosystem services

摘要: Protecting wetlands in cities is challenging. A cost-effective spatial prioritization approach taking into account stakeholder motivations needed to identify of conservation interest. This study aims optimize the efficiency a systematic planning (SCP) protect nine urban wetland ecosystem services (ES) and biodiversity. First, we mapped ES supply demand capture their variation as they occur at scale. Secondly, using property value cost data, compared SCP two multicriteria scoring approaches. Thirdly, alternatives by changing unit scale objectives (i.e. emphasizing focusing on most important ES). The total networks was minimally 13 times higher, when Consequently, approaches were least five less efficient than per network area ($/m2). Decreasing size units resulted further reduction, with that up 92% costly. We also highlighted beneficiary fulfillment could be optimized without loss efficiency. Finally, secured for same expenditure required four public safety related ES. However, solely these failed represent those other Our results may provide tool better inform land use decision order mitigate impacts growth
