Food and agricultural systems in the global South have undergone recent and significant transformation. Such changes are driven by an array of actors, and alongside social, political and economic forces, including a renewed investment by global development actors following the global agri-food crisis in the mid-2000s. The global agri-food crisis, in particular, is associated with speculations in food and agriculture, alongside the introduction of new modernisation policies and programmesincluding the Alliance for a Green Revolution in Africa. Such interventions are often couched as a response to the challenge of feeding the world's growing population, estimated to reach nine billion by 2050. In Africa, an agricultural transformation is also closely tied to initiatives to modernise agriculture, including expanding export-led agricultural development. Turning to Ghana in particular, market-based and export-led agricultural development policies and narratives have expanded since at least the mid-2000s, incorporating new actors, and extending their local level impacts. During this period, dominant agricultural development narratives framed Ghana's agrarian problems as largely technical and supply-side problems, which could be solved by increasing productivity as well as diversifying into production of export crops, thereby addressing poverty, food insecurity and global market access issues. In particular, the promotion of cashew nut production as export diversification has integrated farmers in the Brong Ahafo Region into the global commodity market. These market-based approaches are shaping agricultural practiceswith outcomes that are transforming agriculture in Ghana, particularly the Brong Ahafo Region. With this as context, this thesis adopts a critical political ecology approach to analyse contemporary processes and outcomes of agricultural transformation in Ghana's Brong Ahafo Region. Political ecology was adopted to render transparent the complex political, economic and sociocultural processes across different global and local scales shaping agricultural transformation in the region, often referred to as the 'breadbasket' of Ghana. The research adopts qualitative methods, including interviews, focus group discussions, observation and policy document analysis, to gather in-depth data on farming systems in the Brong Ahafo Region.
