Export horticulture in Kenya viewed as an agro-industrial food system is currently the fastest growing agricultural sub-sector in terms of foreign exchange earnings. Increased demand for horticulture products led to production spreading beyond the traditional mountainous high yielding areas into arid and semi-arid zones as in Northwest Mount Kenya. This food system competes with other food systems for common pool resources needed for the production of food. We argue that local actors, especially poorer households lack the power to influence the institutions (‘rules of the game’) of production and resource ownership by which the dominant agro-industrial system impacts their livelihoods.This paper is structured to include the following sections: the introduction, materials and methods, results, discussion and conclusions on the challenges and opportunities in export horticulture as an agro-industrial food system: case study of Northwest Mount Kenya region
