Abstract

The role of agriculture in an agrarian economy like Nigeria as a pathfinder to understanding the sustainability of the environment cannot be over emphasized, rapid, largely unchecked, urbanization is common in many urban centres such as the Lagos metropolis. Associated with these are the key problems of urban poverty and food security, urban land market, and issues related to sustainable urban development. Urban agriculture (UA) is in reality and in many cases a response to crisis and a coping strategy of the urban poor UA can contribute to food security in several ways. It increases the amount of food available and enhances the freshness of perishable foods reaching urban consumers. UA can also play a role in environmental conservation. However, UA production systems can pose risks to public health and the environment. These arise from the inappropriate or excessive use of agricultural inputs-including pesticides, nitrogen, and raw organic matter containing heavy metal residues. Urban land use planners should endeavour to promote multifunctional land use, and greater community participation in the management of urban open spaces as a way of integrating UA as a key concept in urban development programmes.

Key words: Urban agriculture, urban land use planning, sustainable land management practices, metropolitan Lagos.
