Scientific impact: In the evaluation of historical places proposed by Mexico for their inclusion in World Heritage, as well as Viñales Valley in Cuba, there were detected and based additional values to those that had been recognized by the national authorities. It provided new elements for the valuation of landscapes with a view to their inclusion in the list of world heritage, the first scientific approach to the subject inside Caribbean area. In 2000, its influence helped designating the system of 191 ruins of French coffee plantations established in the mountains between Santiago de Cuba and Guantanamo in the 18th and 19th centuries. For the purposes of monitoring systematically patrimonial places in general, it identifies and classifies the factors that affect them, establishing a tool to measure their effects. It achieved for the first time, in the reactive monitoring, an integral identification of the factors that affect Ancient Guatemala - World Heritage since 1979 - and the threat degrees to its integrity. It defined a conceptual basement for teaching in heritage administration. It demonstrated the need to establish a regional formation system in patrimonial administration promoted by UNESCO, with the support of member states. It established the premises of the system and, starting from the study of a group of academic alternatives from Europe, USA and Latin America, it proposed program models to graduate teaching, which can be adjusted to the specific needs of each country. The section dedicated to the formation of specialists constitutes another kind of work, fundamental in any conservation strategy of the Heritage, and it carries out contributions that have already been recognized. It was able to identify and synthesize the advances achieved in three decades of application of the Convention of World Heritage in Latin America and the Caribbean, as well as the problems that the Region faces in this regard. These elements contributed to the final report subjected in June of 2004 by the Center of World Heritage, UNESCO, to the Committee of World Heritage and to the elaboration of action plans in the next years.

Socio-economic impact: The work embraced socio-cultural, patrimonial, economic, territorial, landscape, urban and building considerations. It has been decisive for the World Heritage’s declarations obtained by Cuban monuments and places. In Guatemala, it formulated proposals that were useful to the authorities in order to establish an improving management plan of that city and to avoid that the World Heritage Committee register it in the List of Endangered Heritage in 2004.
