Urban Agriculture and Physical Planning: A Case Study of Zaria, Nigeria
Zaria, located in Kaduna State, is a medium-sized city with an estimated population of 547,000 and a growth rate of 3.5 per cent per annum (Ministry of Economic Development, 1996). Its development and growth is attributed to its location in northern Nigeria and because historically Zaria has been a centre of learning with specialized training and research facilities. Agriculture is by far the most important activity of the working population. Approximately 40-75 per cent of Zaria’s working population derive their principal means of livelihood from agriculture (ABU, 2000). Pressure on land tends to decrease as distance from the city centre increases – just as the percentage of people farming increases. The agricultural activity in Zaria can be divided into two types: rainfed and irrigated farming.
