In scenario studies of biodiversity and ecosystem services, the population distribution is one of the key driving forces. In this study, we developed a coupling method for narrative scenarios and spatially explicit residential and working population designs for all of Japan as a common dataset for ecosystem scenario analysis implemented by 5-year project entitled “Predicting and Assessing Natural Capital and Ecosystem Services (PANCES)”. For more details, please refer to https://rdcu.be/cv5Gk I introduced our gravity-based population allocation model. And I and Dr. Hori demonstrated Scenario simulation of grid population by gravity model. We discussed the application of the simulation and future collaboration with all participants.
