15 p., The results of a study in Sri Lanka, combined with a review of the literature, provide evidence that Farmer Field Schools (FFS) can contribute to increasing farmers' skills and lowering insecticide use in rice. However, there are questions about their capacity to reach the majority of farmers and there's little evidence that skills learned are passed to nonparticipants, or that an FFS is a likely basis for sustained group activity. The results draw attention to the problems of relying on simple formulas in agricultural programs and point to inadequacies in the assessment of donor projects.
22pgs, We introduce the “coordination frontier” (CF), a simple practical tool to assess the likelihood of success of voluntary coordination in situations where, ex ante, the collective action solution provides an appealing alternative (e.g., for pest and disease control). We demonstrate the value of information conveyed by the CF, explain how to construct the CF from experimental data, and show how to apply the CF in practice. We illustrate the concept with an application to data from a framed field economic experiment, which was designed to elicit the preferences of Florida's citrus growers regarding their willingness to coordinate actions to combat citrus greening disease. This is a highly relevant case study not only because of the significant impact caused by citrus greening on Florida's citrus industry but also because a voluntary area-wide pest management program to control it had been established in 2010 and eventually failed; a similar program is now in place in California, where the disease spread is at an earlier stage. Had the CF been available in Florida, estimates of the (aggregate) chances of successful coordination could have been shared with growers to update their beliefs regarding the chances of successful coordination to help reduce strategic uncertainty. Policymakers in California could use the CF in such way and devise ways to encourage participation to increase the chances of reaching a desired coordination threshold.

Notes:
16 pages. It can be found in IDEALS on the university library page., THE CHINCH BUG is one of the three or four most destructive crop pests known in the United States.
Ever since the Illinois prairies were first cultivated, chinch bugs have been collecting a heavy g rain rent from the corn growers of the state. A loss of practically 6 1/2 million dollars to the farmers in 17 counties in southwestern Illinois is estimated to have resulted from damage
done by these insects in one year when the bugs were numerous. This loss was from direct damage to corn, wheat, and oats, and did not take into account damage to other crops and secondary losses.
This circular tells how to combat this pest by growing crops on which the chinch bug does not feed, by adjusting rotations, by planting varieties of corn that are relatively resistant to chinch bug damage, and by building effective barriers to prevent the bugs from invading fields
of corn. By the timely use of these various methods, chinch bug damage can be largely prevented.
