Modelling Multi-regional Ecological Exchanges: The Case of UK and Africa

Against this backdrop, the current work draws upon the theoretical constructs of multi-regional input-output (MRIO) framework to trace country specific sectorial-level flows of the aforementioned metrics between a representative developed nation, UK, and 27 African regions in order to fully examine their ecological exchanges. Key findings in the study suggest that for water consumption and land use, there is a net externalisation of these impacts for all the 27 African regions by the UK. It was also determined that the extent of the imbalance between the UK and the African region is exceedingly far greater for water consumption. It is recommended that in formulating a robust multi-national environmental policy where so many factors are at play, country specific and industry targeted approach to ecological unequal exchange between nations provides better and improved insight into addressing ensuing environmental issues.
