  3. 3. Food for Naught : The politics of food in agricultural modernization for African smallholder food security

    Sammanfattning : Why is there hunger in sub-Saharan Africa? What forces drive the global food system? What is the global food system?

Proceeding from a critical realist approach, focus of this study is on the challenge of African smallholder food insecurity and how it is presented as part of a dominant discourse of agricultural modernization.

  4. 4. Global trade, food production and ecosystem support : Making the interactions visible

    Sammanfattning : The concept of producing energy from biomass has, for the last two decades, occupied attention of policy-makers, private industries, researchers and civil societies around the world. The highly contested and contingent character of the biofuel production, its entanglement in the nexus of three problematic issues of energy, climate and agriculture, as well as its injection into the current socioeconomic arrangements, is what makes it timely to analyse.
