Beyond Group Ranch Subdivision: Collective Action for Livestock Mobility, Ecological Viability and Livelihoods

Introduction Pastoralism is the dominant land use in 25% of the world’s landscapes and comprises the basic subsistence strategy of 20 million households (Galaty and Johnson 1990). These rangeland ecosystems largely occur in regions too dry for rainfed agriculture, and are characterized by recurrent drought and strong intraand inter-seasonal variability in climate (Ellis and Galvin 1994, Galvin et al. 2001). Historically, the primary pastoral response to minimize risk has been mobility. Opportunistic and extensive seasonal livestock movements provided access to water and forage resources that were heterogeneous (i.e., patchy) in space and time. This mobility occurred largely in the context of communal land tenure systems – wherein flexible use rights were negotiated through layered memberships in kinship, clan, and lineage groupings (Bekure et al. 1991, Lane and Moorehead 1994, Turner 1999). Recent developments in ecological and common property theories clearly support the logic of pastoral mobility to compensate for resource heterogeneity (Ellis and Swift 1988, Ostrom et al. 1999, Illius and O’Connor 2000). However, over the past three decades, a combination of government policy and internal drivers has pushed pastoral systems in the opposite direction, towards privatization of communal rangelands characterized by little flexibility (Galaty 1992, Niamir-Fuller 1999, Blench 2001). Many scientists are concerned this transition from mobile systems to continuous grazing of private parcels will lead to ecological degradation and spiraling poverty among pastoral households, and a gradual decrease in both system stability and sustainability (Ellis et al. 2001, Agrawal 2002, Reid et al. 2003, Boone and Hobbs 2004). Pastoral producers in East Africa face a critical dilemma. They are caught between new land tenure rules associated with the dissolution of group ranches and subdivision of communal
