Does community-based tenure prevent land grabbing? The oil palm case in Mexico

The recent oil palm expansion has resulted in significant land losses for rural communities globally, raising concerns about food security, poverty, and the loss of common resources. This study investigates whether community-based tenure regimes in Mexico, particularly ejidos, prevent land grabbing and land concentration in oil palm producing regions. By mapping oil palm plantation types (smallholdings, mid-sized and large-scale plantations) across major land tenure regimes (ejido, communal and private property) using high spatial resolution imagery from Google Earth and ESRI/Maxar, we explore the relationship between tenure forms and land concentration. Our findings suggest that ejido lands largely prevents land grabbing by oil palm, although neoliberal reforms have favored land concentration, especially under private tenured land (southern Campeche) but also in some ejidos facing illegal land-based investments (Lacandon rainforest). This research contributes to broader debates on oil palm, tenure regimes and land grabbing, highlighting the need for land tenure policies that protect rural communities from industrial plantation encroachments.
