      abstract = {The paper assessed agricultural production systems from a  sustainability perspective defined in terms of relatively  homogeneous agro-ecological zones of Africa, using the  framework of a production function. Data used were drawn  from FAOSTAT, the National Centre for Atmospheric Research  and World Bank Indicators respectively for the period  1961-2009. The data were separated into three sub periods,  namely: entire period (1961-2009), the pre-Structural  Adjustment Period (SAP) reform period (1961-1985) and the  post SAP reform period (1986-2009). This was necessitated  by the need to examine whether production systems may have  been shifted out of the overall trajectory of system  evolution by shocks e.g. policy (SAP) among others. To  investigate whether there has been a degradation of the  quality of the natural resource base across the diverse  agro-ecological zones; the estimated TFP trends were  related to changes in selected resource quality variables  over time. The results showed that the Northern and  Southern agro-ecological zones had non-negative trends in  TFP, indicating sustainability of production systems.  However, the result indicated that the policy instrument  (structural adjustment programme) may have shifted farming  or production systems out of the overall trajectory of  system evolution in three out of the five agro-ecological  zones studied which showed negative TFP trends. A  degradation of resource quality over time was noted during  the pre-SAP reform period, but was maintained during the  post-SAP period.},
