International migrant workers and extensive agricultural systems This chapter explores the role of international migrant workers in mountainous, island, and inner territories that cover large parts of Mediterranean Europe (Greece, Spain, and Italy), where intensive and mechanised agriculture is not feasible due to agro-ecological features and the nature of the terrain (steep, remote, rocky). The modernisation process that unfolded in the aftermath of the Second World War has further pushed agriculture towards more market-oriented and capital-based patterns. As a result, these settings have been marginalised and undergone longstanding decline, leading to economic crisis, demographic regression, and land abandonment (Jentsch and Simard 2009, Nori and Farinella 2020). Here agro-pastoral systems-the extensive livestock rearing of mostly sheep and goats (but also cattle, horses, and pigs) based on natural or cultivated grazing and complemented by forms of crop farming-still represent a main source of local livelihood. As shepherding has become a less attractive opportunity for local populations, labour is today increasingly provided by international migrants. This chapter presents the results of extensive fieldwork based on ethnographic observations, field notes, and semi-structured interviews with some 170 stockbreeders and 50 international migrant shepherds over the last five years in different regions of Mediterranean Europe: Greece (Peloponnese and Thessaly), Spain (Cataluña), and Italy (Piedmont, Trivento, Abruzzo, and Sardinia). Qualitative research was conducted by the authors, with semistructured interviews collected both directly and through collaborators. Agropastoral settings provide an original perspective because most European literature (among others, Ortiz-Miranda et al. 2013, Gertel and Sippel 2014, Corrado et al. 2016) focuses on migrants' presence in intensive agricultural systems that characterise high-potential areas, while limited research explores other production systems (Rye and Scott 2018).
