Abstract
The cultivation of food crops within the overall boundaries of towns and cities is not new, but has been forgotten or ignored in the last 20 years, while urbanisation has, it is thought, absorbed a disproportionate share of national resources. Can, however, an alternative form of urban development, less greedy of financial and natural assets, capable of satisfying the basic needs of the population and of reducing the vulnerability of the poorest, be envisaged, and is the food and energy system an appropriate starting point?1The first stage in studying any neglected area is to review existing evidence and policy, in order to reveal gaps and suggest avenues for future enquiry, policy formulation, and experiment.2In this article, the evidence presented will be from Zambia, and it will be the task of further research to assess the relevance of these findings to other towns and cities in the region.
