La tabacchicoltura nel Salento dal 1929 al 1993: possibili implicazioni sanitarie. (Tobacco cultivation in Salento (Apulia Region, Southern Italy) from 1929 to 1993: possible health implications).

The Province of Lecce (Apulia Region, Southern Italy) is one of the Italian areas where the prevalence of respiratory disease and cancer of the respitartory tract is very high. Through a descriptive analysis of the historical series of tobacco culture indicators, a historical reconstruction of the development of tobacco cultivation in Salento (the area where the Province of Lecce is located) is here presented, in order to provide an additional element of knowledge on potential risk factors for respiratory diseases and cancers. Data regarding extensions in hectares and crop productions in the province of Lecce, in Apulia, and in Italy are from the Chamber of commerce of Lecce province and from the Italian National Institute of Statistics (Istat). From 1929 to 1993, the province of Lecce provided between 75% and 94% of the tobacco cultivated in Apulia Region and 25% of the national tobacco until 1945. Since the late Sixties, a growing increase in annual average production was observed, reaching 21.5 quintals per hectare in 1991 in Salento. This large tobacco production, associated with intensive use of pesticides, could be an element to be observed in analytical studies as a determining potential for the high prevalence of respiratory diseases and pulmonary cancers in the male population of the province of Lecce.
