Many large-scale land acquisition studies focus on the role of powerful transnational corporations, foreign and domestic governments. Instead, we shift the focus to the role of local actors, in this case, pastoralists in Samburu County, Kenya. Here, we apply the concept of ‘intimate exclusion’ and show that pastoralist elites' desire and ability to maximise productive and financial gains from customary land, coupled with their privileged understanding of land-related laws and regulations and ability to use or threaten others with violence, enables the control of extensive customary lands and the exclusion of weaker pastoralists. These processes, we find, are rooted in the country's capitalist development trajectory traceable to colonial rule. Overall, the paper highlights local ‘homegrown’ actors’ role in large-scale land acquisition, how social intimacy provides space and opportunity for unequal benefits and how historical gains offer unique opportunities to gain from new political and economic developments.
