D.E.C.A. srl was founded in 1978 as a company operating, at national level, in the field of services for the management of greenery, environment and facilities management. 
Since its beginning, DECA has achieved 80% of its turnover in green maintenance and environmental hygiene activities, and since 1997 it has also started managing complex facilities for Telecom Italia Spa.
By carrying out these activities of green maintenance and environmental hygiene DECA is able to work in 9 regions of the Italian territory, managing about 1,865,778 square meters of green surfaces, having to clean about 480,000 square meters of paved surfaces in over 8750 sites and taking care of 730 indoor plants. 
Also for Telecom Italia, DECA has created “Parco dei Medici” in Rome, where it has entirely managed the project for the arrangement of pedestrian areas and green areas outside the site’s complex.
Currently DECA collaborates with small and large companies, including among its existing contracts the Municipality of Quartu Sant’Elena, the Tiber and Agroroman Remediation Consortium, Inwit, Ater Roma and many others.
Based on over twenty years of experience in managing services for customers with facilities spread throughout the country, around the 90s created within it a highly qualified IT sector dedicated to software development and a department dedicated to Research and Development of advanced technologies in the scientific field.
The first practical applications began in the 2000’s with the use of a prototype of a web-based platform and of a mobile APP in ASP (application server provider) mode for maintenance activities, commissioned by Telecom Italia Spa, of greenery in central-southern Italy. In 2005 Telecom requested the use of the GlobalGest platform, created by DECA srl, for the maintenance, verification and control of infrastructures and equipment for 16,000 radio base stations scattered throughout the national territory. 
In the same period, a scientific collaboration with Telecom and CREA (Council for Research and Experimentation in Agriculture) began for the use of GlobalGest in agriculture.  This is how Agrivelta was born, a service that is heading towards precision agriculture, and that has highly technological characteristics able to meet the increasingly pressing needs of renewal and competitiveness of agricultural enterprises in an eco-sustainable logic. The objective is to use Artificial Intelligence techniques to achieve and maintain high qualitative and quantitative standards.
