Abstract
Food production systems in south-east Africa face a persistent puzzle: despite the implementation
of numerous plausible food availability policies, the region's history is characterised by many
cases of food production systems that have underperformed by not feeding the relevant population.
This puzzle is addressed by investigating the dynamics of the region's food production systems. A
theory-based framework is proposed to describe the interaction of biological and socio-economic
processes that determine the availability of food calories. The framework is translated into a
formal model and computer simulation used to analyse its dynamics in a population growth scenario
together with different policy interventions. The results suggest three key concepts for
understanding the performance of food production systems: stock management of soil organic matter,
policy effort threshold, and land use anticipation. These concepts constitute theoretical
approaches to explaining how dynamic interactions can create the puzzle of potentially beneficial
policies failing to provide
enough food calories. |
