Extractive workload: a mixed-method approach for investigating the socially differentiated effects of land-use/land-cover changes in a southern Zambian frontier

Abstract

In rural regions across the globe, local natural resources (i.e., “bush” resources) are central to meeting daily household needs. Culturally-influenced gender- and age-based divisions of labor guide the harvesting of these resources and, as a result, shifts in resource availability will differentially affect women, men, girls, and boys. This research brief presents results of an innovative pilot project designed to assess the socially differentiated effects of land-use/land-cover changes (LULCC) on Gwembe Tonga migrants living in Kulaale, an agricultural frontier in southern Zambia. Integrating existing analyses of remotely sensed imagery with a seasonal resource survey and mapping exercise (n = 20 homesteads), this study finds the average extractive workloads (mean annual distance traveled for the collection of bush resources) of women, men, girls, and boys to be both unequal and contrary to recent speculations about the distinctive vulnerability of adult women to environmental change. Drawing on qualitative ethnographic methods—including semi-structured interviews (n = 101), a homestead labor survey (n = 38), participant observation, and references to over fifty years of anthropological research—the author identifies additional variables—including the demographic structure of Kulaale homesteads and the flexible division of subsistence labor—that color Gwembe Tonga migrants’ aged and gendered experiences of LULCC. The study adds important nuance to our understanding of natural resource practices and individual-level vulnerability, particularly in the face of contemporary environmental change.
