This paper explores reduced form determinants of the adoption of certain technologies by upland rice and soybean farmers in the Center-West region of Brazil. We merge community level data on the availability and quality of publicly provided infrastructure, principally extension, to the farm level data containing information on farmer human capital as well as land quantity and quality. By using community level measures of availability and quality of extension, we avoid problems of endogeneity of farm level measures of extension use. We find positive impacts of farmer education on the diffusion process, in accordance with other studies. We also isolate effects of the quality in regional extension investment as measured by the average experience of technical extension staff. These results indicate that investments in human capital of extension workers does have a payoff in terms of farmer adoption of improved cultivation practices.
14 pages., his paper evaluates the effect of the Rural Capacity Building Project (RCBP),
which aimed at promoting growth by strengthening the agricultural service systems
in Ethiopia, and by making them more responsive to smallholders’ needs, in particular women farmers. We examine the gender-differentiated impact of the RCBP
using panel data on 1,485 geographically dispersed households in project and control
kebeles. We find that women farmers’ access and satisfaction with extension services
increased significantly immediately after the start of the project, but that effect did
not last into the medium term. The project led to an increase in the adoption of high-
value crop farming, area of land cultivated, and economic participation of household
members, benefiting male- and female-headed households equally. Results point to
the positive impact of incorporating women’s needs and constraints in the design of
the agricultural extension system. However, the project was not able to reduce the
preexisting gender gap in agricultural outcomes.
12 pages, Using a nationally representative sample of farm households from India, this paper examines the impact of use of information on net farm incomes. Employing methodologies that mitigate potential biases in the estimation of the impact, the empirical results show that farmers who use information realize over 12% higher net returns per hectare. The paper also establishes a pecking order in access to information. Small farmers and those at the bottom of social hierarchy (based on caste) have access to fewer information sources, and they depend more on informal social networks and input dealers for their information needs. The larger farmers and those from upper caste rely relatively more on sources such as radio, television and newspaper.
search through journal, The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water in a single-farm framework. The analysis provides a conceptual and methodological framework for investigating the expected value of sample information (EVSI), as well as an efficient tool for empirical application. Although a few approximations have been used, the results provide an estimate of EVSI and indicate the need for additional information (original)
