A research programme (acronym: ‘Mo-Global') entrusted to the Planning Studies Centre by the Italian Ministry of Environment in 1989, after just having finished the famous Bruntland Report of the ‘Commission for the Environment and Development of the United Nations'. On the eve of a regional sequel (for Europe) based on a Conference (Bergen, Norway, 8-16 May 1989) which was organised in cooperation of the Norwegian Government with the Economic Commission for Europe of the United Nations.

The Italian Minister of the Environment (Sir Giorgio Ruffolo) welcomed the suggestion to proceed to a study on the state-of-the-art in regard to the design applied to the whole development of the planet Earth. The project was to collect all the most important ‘global models' of the world which have been elaborated up to this epoch, to re-discuss the methodologies, the organisation and the approaches in the face of a more intense cooperation and coordination at the ONU head quarters of technology of the global models.

The Planning Studies Centre – originator of the proposal – entrusts the direction of the undertaking to one of their most reliable scholars of the matter and his associate, Professor Roberto Vacca, who puts together a study Group consisting of Valerio Franchina, Riccardo La Pera, Roberto Nenzi and Carlo Sessa. The Director of the Planning Studies Centre, Franco Archibugi, contributes as a proofreader and annotator of the final Report.

In 1990, the study Group ended its work and the Planning Studies Centre submitted it to the Ministry of the Environment, hoping - in a big national as well as international discussion - on the development of the work and on its publication on behalf of the Ministry, the owner pf the rights of the research. After several promises, the interest for the research fades and the Centre can only re-propose the publication of the Centre's research Report a couple of years later (the global development models etc.). The most part of the contents of the research are still valid, also because in the last ten years there have not been produced many novelties and new models. Only the role of the United Nationes in promoting the development of technology and of the foresights to a planetary scale has blurred, after the furst and last attempts that have been carried out under the guidance of Jan Tinbergen as President of the Committee of Development Planning, and the Progetto RIO (Reshaping International Order) which the same Tinbergen (first Nobel Prize of Economy in 1969, together with Ragnar Frisch) tried to launch between the years 1973 and 1976, together with many other scholars of the international association.

You can have a look at the above indicated index of the Mo-Global research of the Planning Studies Centre enclosed to the poster of the research publication, and hereupon following, the introduction to the research Mo-Global, of which the finality and results can be deducted.
