Large-scale agricultural investments in Eastern Africa: consequences for small-scale farmers and the environment

摘要

Available empirical evidence about the impacts of large-scale agricultural investments (LAIs) in low-income countries is skewed towards the assessment of economic benefits. How LAIs affect land use and the environment is less understood. This study assesses how small-scale farmers living close to an LAI perceive the changes LAI's inflict on land use, land management, and tree cover in Kenya, Mozambique, and Madagascar. It also investigates their perceptions regarding LAI's impacts on the general environment and people's health, as well as on employment opportunities, infrastructure, and conflicts. 271 small-scale farmers were interviewed and their perceptions supported by a remote-sensing-based analysis of land use and land cover changes. Results show that LAIs contributed both directly and indirectly to deforestation in Mozambique, triggered changes in small-scale farmers’ agricultural land management in Kenya, and caused pastoralists to lose access to grazing land in Madagascar. Despite some benefits from employment opportunities and infrastructure improvement, the majority of respondents perceived the overall impacts of LAIs as negative, highlighting reduced access to land and water, pollution, health issues, and unsatisfactory working conditions. We urgently need to invest in devising concrete transformative options to improve LAIs’ contribution to sustainable development in their host countries.
