- Abstract:
- Agricultural development is a major pathway out of poverty in rural Africa. The cultivation of cash crops for sale alongside subsistence crops helps improve livelihoods and alleviate poverty in rural communities. The productivity of these farming systems relies on services provided by the agro-ecosystem within which they occur. These services include fertile soils, the control of pests and diseases, and crop pollination by wild animals. We know that some agricultural systems can damage these services in the longer-term - soil fertility declines, pest and disease outbreaks become more common, pollination levels are reduced. This means that although rural livelihoods might be improved by agricultural development in the short-term, ecosystem degradation and the associated loss of ecosystem services might threaten these gains in the medium to long-term. Has agriculture in sub-Saharan Africa exceeded the capacity of ecosystems to support it? If so, what implications does this have for poor people in rural communities? Are there pathways rural communities might choose to take that enable them to benefit from agriculture-based livelihoods without risking longer-term ecosystem damage? Answering these questions is currently very difficult because a comprehensive understanding of the relationships between agricultural development, wealth distribution and socio-economic opportunity, governance systems, and ecosystem health is largely lacking for the smallholder farming systems typical of sub-Saharan Africa. There is, therefore, a major research challenge in this area that our proposed project aims to address. We plan to explore the ecosystem limits to poverty alleviation in African forest-agriculture landscapes. Specifically, we plan to focus our work on a cocoa farming landscape in Ghana, and a coffee farming landscape in Ethiopia. Ghana and Ethiopia provide an opportunity to study forest-agriculture ecosystems that have contrasting recent development trajectories, levels of rural poverty and ecosystem health. In Ghana, agricultural development has significantly contributed to improved rural livelihoods but may have pushed forest-agriculture ecosystems beyond their limits; whereas in Ethiopia agricultural development is an important potential pathway out of poverty for the rural poor but it is unlikely to have pushed ecosystems beyond their limits yet. By studying these contrasting situations, we hope to provide the scientific evidence that helps rural communities avoid the potentially detrimental effects of ecosystem degradation and hence have more sustainable livelihoods in the longer-term. To do this, we plan to explore (i) the limits to the services provided by forest-agriculture ecosystems resulting from agricultural expansion and intensification; (ii) the key social processes that maintain forest-agriculture ecosystems within these limits or move them beyond them; (iii) the role poverty plays in the processes that determine whether or not ecosystem limits are reached and exceeded; and whether ecosystem limits in turn affect poverty; and (iv) the potential pathways out of poverty rural communities might take; the potential risks ecosystem limits pose to these pathways; and how communities might act to reduce or minimize these risks.
