Main drivers of the evolution of grazing in the alpine area of Valli del Leno (Trentino, Northern Italy) during the last two centuries: natural resources, labour and investment.

In the Alps as in many mountain areas, livestock farming has constituted an important source of income, especially since the Middle Ages. The importance of livestock farming within the Alpine economy has changed over time due to the dynamics of supply and demand combined with evolving environmental, technological and institutional constraints. This paper focuses on the latter aspect and attempts to reconstruct how the relative importance of the production factors of land, labour and capital changed throughout the nineteenth and twentieth centuries in a mountainous area of eastern Trentino. The underlying objective of the investigation is to provide a micro-level empirical basis for hypotheses advanced in the literature regarding the evolution of a crucial sector in the Alpine economy, drawing attention to the long-term role of exogenous and endogenous factors as well as elements of continuity and change. The work is grounded in multiple sources drawn from local archives and official statistics. It demonstrates the flexibility of local communities in managing to sustainably utilize local resources over several periods.
