Assessment of Land Consumption for SDG Indicator 11.3.1 Using Global and Local Built-Up Area Maps
2020
Built-up area mapping is essential task for Sustainable Development Goals (SDGs) indicators related to sustainable cities and communities. The calculation of indicator 11.3.1: “Ratio of land consumption rate to population growth rate” can be used by governments and decision makers for efficient smart city growth monitoring and planning. In this work, the built-up area map based on local data were built by using land cover classification approach for smart cities, developed in Horizon-2020 ERA-Planet SMURBS project. These maps were validated and compared with use of Global Human Settlement Layer, ground truth data and Maryland Forest product. The results shows that global products, such as Global Human Settlement Layer are very useful and have good accuracy especially in the case for global indicator 11.3.1 assessment. It can show the full picture of global urbanization changes. But, it is better to use local data for city scale, to provide accurate tracking of urban area development. Local data in this case could be more informative for the decision makers in purpose of the city growth management and proper use of environmental resources.
