Abstract
Determining Technical Efficiency Index (TEI) of urban farming is central to selection and
profit realization by urban agriculture farmers. It has been populated that technical
efficiency indices can be useful tool in planning for Urban Agriculture (UA). This study
was conducted in three selected municipalities to assess Urban Agriculture (UA) indices
and some issues of Technical Efficiency. Municipal and city bylaws for regulating and
controlling UA practices and their contradictions were examined. Socio-economic factors
influencing UA and extension services provision were assessed. The technical efficiency
levels of the selected UA enterprises were determined and compared. Data were collected
from 270 respondents in the three studied municipalities. Results showed that UA was
found across all density areas and majority of city dwellers practice it. Municipalities
recognized UA and set regulations for regulating and controlling it. Despite of urban
farmers having entrepreneurial acumen, they faced several challenges in resources and
marketing. Land size, total variable costs, and extension service charges impacted on TEI.
The highest TEI was achieved by keeping broilers, followed by keeping dairy cattle.
Keeping layers ranked third and growing vegetables had lowest TEI. TEI levels declined as
one moves from low to high density area. TEI were relatively higher with lower UA units
in large animals (cattle) and higher for those who kept larger numbers of poultry. It was
recommended to; (a) revisit the set municipal bylaws for regulating and controlling UA; (b)
revamp a sound agricultural extension delivery system; (c) Improving support services
delivery for promoting uptake of innovations by UA farmers. Further, Exploring profitable
innovations for promoting UA in urban setting, carrying out TEI analysis of all UA
practices to ascertain TEI levels and UA units for profitable UA enterprises combined with
thorough market analysis of UA products and undertaking feasibility study on possibility
and profitability of undertaking other types of UA enterprises like fish farming in tanks and
or concrete ponds, would highly enhance UA in our cities.
