17 pages., Via online journal., This article provides new estimates of the marginal product of public agricultural research and extension on state agricultural productivity for the U.S., using updated data and definitions, and forecasts of future agricultural productivity growth by state. The underlying rationale for a number of important decisions that underlie the data used in cost‐return estimates for public agricultural research and extension are presented. The parameters of the state productivity model are estimated from a panel of contiguous U.S. 48 states from 1970 to 2004. Public research and extension are shown to be substitutes rather than complements. The econometric model of state agricultural TFP predicts growth rates of TFP for two‐thirds of states that is less than the past trend rate. The results and data indicate a real social rate of return to public investments in agricultural research of 67% and to agricultural extension of 100+%. The article concludes with guidance for TFP analyses in other countries.
11 pages, Changes occurring in the Extension environment include that of climate. Reduced and sporadic rainfall is among the effects of climate change and variability with consequent negative effects on food production. Smallholder agriculture in most developing countries world-wide, including South Africa, is largely rain-fed. Extension agents, therefore, need to constantly improve their capabilities to remain useful to farming communities. The purpose of the paper is to determine Extension agents' climate variability coping competencies required to effectively support smallholder crop farmers' production. The study adopted a multi-stage random sampling approach to site and respondents' selection. Semi-structured questionnaire was used to collect data in 2014 from smallholder crop farmers in four municipalities of Limpopo province. Information was also collected from Extension managers and field-level extension agents of the Limpopo Department of Agriculture by means of questionnaires. The most popular climate variability coping strategy promoted by most extension agents was conservation agriculture. Small yield differences between Extension service-recipients and non-recipients indicate that Extension support has minimal effect on farmers' production. Agents need new competencies regarding correct application conservation agriculture. The study recommends the involvement of extension agents, scientists and farmers in adaptive trials for effective implementation of conservation agricultural practices to improve crop yields.
10 pages., Via open source journal., Farmbook is a novel information communication technology (ICT) tool for agricultural extension that is currently being field tested by the Catholic Relief Services (CRS) in Southern and East Africa. Farmbook enables extension agents to assess productivity and profitability of farming enterprises in a faster and more reliable manner, so as to increase farmer incomes and achieve food security. This study looked at the relationship between challenges faced by extension agents testing the Farmbook application and select socio-economic indicators influencing their work. Specific objectives were to identify and categorize the challenges facing extension agents in the field as they used Farmbook, assess gender differences in the use of Farmbook by extension agents, understand the relationship between socio-economic status of extension agents and the challenges faced in using Farmbook. Data were collected through document reviews, administration of a structured questionnaire and focus group meetings with field agents. Descriptive statistics and multivariate techniques were used to analyze data. The results show that personal and wider socio-economic conditions do have an impact on the proficiency of extension agents using Farmbook. The study goes on to recommend measures to improve the training and ICT proficiency of extension agents adopting Farmbook
