While the term 'geodesign' was occasionally used earlier by some scholars with fairly different meanings, its current concept is due to the scientific debate originating in a series of meetings held in California in the early 2000s. A first workshop on 'Landscape Change', funded by the National Science Foundation and by the Environmental Systems Research Institute (Esri), was held in 2001 in Santa Barbara, California, when a group of scholars in Landscape Architecture and Planning, and in GIScience (http://www.ncgia.ucsb.edu/landscape/landscape.htm) started a new debate on how to bridge the gap between the design professions and GIScience (Goodchild, 2010;Wilson, 2015). Later in 2008, a second workshop on 'Spatial Concepts in GIS and Design' was held, again in Santa Barbara (http://www.ncgia.ucsb.edu/projects/scdg/), by the same core group of specialists interested in investigating to what extent the fundamental spatial concepts that lie behind geographical information systems (GIS) were relevant in design.Since the first meetings, where leading scholars from landscape, urban and regional planning and GIScience met together with Esri, the major player of the GIS industry, the term has been occasionally used as a marketing buzzword in the GIS business world. Nevertheless, the work of the original group of scholars attracted the attention of a constantly growing and active community of researchers, educators and professionals in spatial planning. In the last decade, every year regular summits and conferences on geodesign were held in the USA (www.geodesignsummit.com) and Europe (http://www.digital-la.de) and occasionally in Asia and Latin America, bringing together GIS and design experts and practitioners from academia, government agencies and non-governmental organisations (NGOs), as well as the private sector, with numbers usually exceeding 100 participants or more from across a wide range of disciplines. In addition, the term geodesign started to appear in the thematic tracks of major international planning conferences and events, such as the annual meeting of the Association of European Schools of planning (Silva and Campagna, 2016) demonstrating the rapid diffusion of the approach. Beside the growing interest by researchers and practitioners, geodesign quickly became the major subject of new academic curricula in the USA (Foster, 2013) and to a lesser degree to date, in Europe (Campagna, 2017).Geodesign literature is also fast-growing, with 118 papers indexed in Scopus since 2014, and an actual positive trend. Most notably, in 2016, a special issue on geodesign was published by the Landscape and Urban Planning journal (Steiner and Shearer, 2016), documenting some of the most
