Developing Curriculum Markers for Agricultural Extension Education in South Africa.
The Journal of Agricultural Education and Extension, 2008Co-Authors: S.h. WorthAbstract:Abstract Sufficient changes have occurred in both the Agricultural and educational sectors of South Africa to warrant a careful scrutiny of the Agricultural education offerings in South Africa. Agricultural Extension is identified as an important part of the intended transformation of the Agricultural sector. Further, Agricultural Extension is essentially an education programme. As such Agricultural Extension should be subject to the same scrutiny—both in terms of Agricultural policy and educational policy. Drawing on two previously published papers, this paper synthesizes the findings of examining Agricultural Extension in these two lights. The result is the establishment of a range of 21 markers, grouped in three categories: meta-markers which address cross-cutting factors in the learning agenda; content markers which are underpinning markers that address theory and practice in areas that impact on all other learning outcomes in the curricula; and process markers which are facets of the learning process...

Privatising Agricultural Extension: caveat emptor
Journal of Rural Studies, 2000Co-Authors: A. D. Kidd, John P. A. Lamers, P.p Ficarelli, V. HoffmannAbstract:Abstract Improvement in Agricultural systems requires good information and sound advice. This has often been provided to farmers through public Extension systems. The paper describes some of the forces that require a reduced role for the public sector in Agricultural Extension and greater reliance on the private sector. Some experiences of privatisation and commercialisation of Extension, as well as the caveats these suggest, are highlighted. A role for the state in Agricultural Extension will continue to be important in many countries for both economic and social reasons. Where forms of privatisation are useful, this will require tested strategies that are situation specific, multi-dimensional, gradual and flexible if resource-poorer farmers are to benefit.

The Effect of Agricultural Extension on Farm Yields in Kenya
African Development Review, 2001Co-Authors: Robert E. Evenson, Germano MwabuAbstract:The paper examines effects of Agricultural Extension on crop yields in Kenya controlling for other determinants of yields, notably the schooling of farmers and agro-ecological characteristics of arable land. The data we use were collected by the Government of Kenya in 1982 and 1990, but the estimation results reported in the paper are based primarily on the 1982 data set. The sample used for estimation contains information about crop production, Agricultural Extension workers (exogenously supplied to farms), educational attainment of farmers, usage of farm inputs, among others. A quantile regression technique was used to investigate productivity effects of Agricultural Extension and other farm inputs over the entire conditional distribution of farm yield residuals. We find that productivity effect of Agricultural Extension is highest at the extreme ends of distribution of yield residuals. Complementarity of unobserved farmer ability with Extension service at higher yield residuals and the diminishing returns to the Extension input, which are uncompensated for by ability at the lower tail of the distribution, are hypothesized to account for this U-shaped pattern of the productivity effect of Extension across yield quantiles. This finding suggests that for a given level of Extension input, unobserved factors such as farm management abilities affect crop yields differently. Effects of schooling on farm yields are positive but statistically insignificant. Other determinants of farm yields that we analyze include labour input, farmer experience, agro-ecological characteristics of farms, fallow acreage, and types of crops grown.
