  1. 31. Rural Income Diversification, Employment, and Differentiation in Kenya and Implications for Rural Change

    Författare :Maria Fibaek; Ekonomisk utveckling i det globala Syd; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Rural Development; Income Diversification; Differentiation; Agrarian Political Economy; Kenya;

    Sammanfattning : To contribute to contemporary rural development debates, the present thesis conducts a contextual analysis of rural development using Kenya as a case study from the colonial era to today. To perform the analysis, two critical trends in rural Africa are focused on: socioeconomic differentiation and rural income diversification, with a particular focus on large-scale farm employment.

  3. 32. Food security in a changing climate : The role of cropland intensification and land acquisitions across Africa

    Författare :Altaaf Mechiche-Alami; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agriculture; land grabbing; sustainability science; Network Analysis; Earth observation; Crop model;

    Sammanfattning : Food security is one of the world’s greatest challenges. The current food system shows an entanglement across the globe which means that local farmers reliant on subsistence agriculture no longer operate in isolation of larger-scale processes within the global economy or the changing biophysical system of the planet.
