The international dimension of CGeo is to be measured at three levels:
CGeo currently intervenes in various R&D platforms, such as the International Geosciences Program (collaborating in the Guide of Stratigraphic Nomenclature and on the Stratigraphic Lexic, or still in the promotion of the Geology Day and geology congresses) or the International Union of Prehistoric and Protohistoric Sciences (securing its general secretariat and intervening in the scientific commissions on technologies, archaeosciences, rock art and heritage, besides collaborating in the organization of the 2006, 2011 and 2014 world congresses). A focal moment of this collaboration in the recent past was the CPLP Geology congress, from which 3 volumes were published.
CGeo, due to the fact that it is involved in research in over 10 countries, also established relevant relations with networks in those countries and respective continents: Europe, Africa and Southern America, mainly, but also with the Asiatic Society or the University of Beijing. Most relevant partners are several European Universities (Tarragona, Complutense, Salamanca and Extremadura in Spain; MNHN, Paris I, Panthéon Sorbonne, Nanterre and Bordeaux 3 in France; Ferrara, Turin and Cagliari in Italy, Jena in Germany, Durham in the UK, etc.) and heritage centres and universities in Africa (Institut Fondamental de l’Afrique Noire in Senegal; INPC and MNA in Angola; national heritage in Namibia; National Museum in Ethiopia; Univ. of Oujda in Morocco), Asia (University of New Dehli and Deccan College in India; Beijing University in China), Australia (Flynders and Melbourne Universities) and Southern America (IPHAN, several universities, Petrobras, IBIO, etc.).
CGeo members also collaborate with thematic networks, and with two main Unesco associates international councils: Council of Sciences (ICSU) and Council of Phylosophy and Human Sciences.
This networking approach extends to the contribution of CGeo members to national networks, such as the Associação Portuguesa de Investigação e Tecnologia (Inovação) em Ciências da Terra (APITCT), the geoturism projects or the HERITY quality assessment of cultural heritage places. This international dimension also benefits the private sector with which CGeo is engaged in various applied geotechnologies.
