Oral Presentation Abstract: Abstract: Nature-based solutions (NBS) are usually described as solutions to societal challenges inspired and supported by nature, which provide social, economic, and environmental benefits. Current NBS assessment toolkits, which assess benefits in the form of ecosystem services (ES), usually do not consider the associated costs during NBS life cycles. Moreover, assessments do not consider changes in ES supply along NBS lifetime, assuming static conditions. In this paper, we present a modelling framework that integrates ES and life-cycle costing (LCC) approaches and considers dynamic conditions to overcome the above mentioned limitations. Based on the modelling framework, a pilot urban forest model is developed and tested in a case study in Madrid (Spain), providing results in biophysical and monetary units. The pilot model assesses two regulation ES classes (regulation of chemical composition of the atmosphere, regulation of temperature and humidity), one provisioning ES class (materials from cultivated plants for direct use or processing), and operational costs due to pruning and management of plant residues. The modelling framework serve as an initial basis for the integration of ES and LCC in the valuation of NBS and similar solutions.
