Local Productive Systems (hereinafter LPSs) based on agro-food industries constitute
alternative models of development in peripheral rural areas that are subject to internal and external
dynamics and processes. The main objective of this research is to investigate these processes and
their consequences on four LPSs based on the Iberian Pig Transformation Industry (hereinafter
LPS-IPTI) in SW Spain: Fregenal de la Sierra, Higuera la Real, Cumbres Mayores and Jabugo. Using
secondary data, a comparison is made between 2002 and 2020 to establish the changes, causes and
consequences on the LPS-IPTIs studied. The results obtained indicate (1) the business and territorial
concentration of LPS-IPTIs; (2) changes in the structure of the LPS-IPTI due to internal and external
causes that were already present before the international economic crisis; (3) productive and territorial
specialisation in standardised products and quality products that generated the polarisation of the
sector; (4) simplification of industrial processes; (5) loss of employment, especially female; (6) external
control of companies in the sector which, accordingly, brings about the loss of prominence of local
actors in favour of foreign companies, reduced social capital and the progressive loss of ownership of the LPS
