Sample text

For extension, the analysis included all projects approved and completed in the review period, as well as a representative sample of other agricultural projects with a substantial extension component. For research, all completed projects and most ongoing projects in an advanced stage of implementation were included, except for the Africa region, where a sample of the large number of participating countries was taken to represent the region's diversity. The design and performance of investments are compared with the recommendations of an earlier review of the subsector produced by OED in 1983, and with a research policy paper released by the Bank in 1980.

The performance record suggests that the Bank has been better at expanding the research capacity of particular agencies within the NARSs than at improving management and overall system efficiency. This is of concern, given the inadequacy of national funding for public research institutions and serious doubts about their sustainability. Although expansion and efficient resource use should not be incompatible, expansion has proven to be the more attainable outcome, and this may have even contributed to the weak results in improving efficiency.

Just as the unavailability of a supply of new relevant technology will lead to diminishing returns of an extension service, so too will a scarcity of funds, which limits the field activities in staff-intensive, face-to-face services. Apparent efficiency and effectiveness, of course, are conducive to funding support. Recommendations Annex 4 of this report elaborates on the recommendations for future and ongoing Bank interventions in agricultural extension. The major thrust of the recommendations is that the Bank give considerably more attention to preproject analysis and give adequate help to borrowers with project preparation.
