World Bank Discussion Paper 126. Washington, D.C. 158 pages., Studies from a workshop. Includes evidence that research and extension had contributed to a decline in agricultural production. "There is a broad consensus about the many factors that have contributed to failures to boost land and labor productivity in Sub-Saharan Africa. Both technological options and agroecological and socioeconomic circumstances in this vast region are diverse, thus creating a complex matrix of impacts and explanations. The central explanation is that research and development activities, whether public or private, national or international, have produced innovations that farmers find variously unprofitable, too risky, or impossible to implement in a timely and useful fashion. These problems lead, in turn, to often declining agricultural productivity and a deteriorating agricultural resource base, particularly of soil and forest resources. Stepping back further from the farmers themselves to the institutions that are supposed to have assisted, the difficulties are several including the poor (often irrelevant for resource-poor farmers) siting of much past experimental and testing endeavor, inadequate and temporally inconsistent staff and budget support for national research and extension organizations.
8 pages., Via online journal, This paper examines the effect of farmers' access to communication technologies (CTs) on farmers' agricultural output at the aggregate level in the People's Republic of China (P.R. China) based on panel data. The paper uses a dynamic Cobb–Douglas aggregate production function and the generalized method of moments (GMM) as estimation techniques to estimate the parameters of interests. The research findings are: the estimated effects (measured by elasticity) of teledensity on the provincial level agricultural output have been positive and statistically significant both in the short and long runs. In the long-run, the size of the effect is substantial: from 0.94 to 1.06. This implies that the agriculture sector of the P. R. China has some potentials to derive benefit from the use of CTs like telephone. Hence, the Chinese government should consider policy support to expand communication infrastructure for the farmers
This study presents an efficient version of test for the hypothesis that education plays a key role in influencing agricultural productivity based on a switching regression model. In the present setting, farmers’ ability to deal with disequilibria is allowed to change with education, which thereby provides a concrete evidence of the effect of education on selected East Asian production agriculture. The results suggest that there exists a threshold for education to be influential to agricultural productivity change when the selected East-Asian economies are categoried by their degree of economic development. Moreover, for the group of economies where education constitutes a major determinant of productivity growth in both the technological progression and/or stagnation/recession regimes, the effect of education is found to vary from economy to economy and from regime to regime. Generally speaking, however, those East-Asian economies tend to reach their turning point in short time despite of the mentioned differences. This result therefore leads to important policy implications concerning giving an impetus to human capital investment in the agriculture sector.
