A POLICY FRAMEWORK ,Rationale for Public Expenditure for Small Farm Activities Determining whether all or some of the gaps identified in the preceding section should be filled, and at what rate, requires the formulation of a rationale for public expenditure for small farm activities. There has not been enough attention devoted to the formulation of a rationale and the measures of program success that would be derived from it. In addition, there has been no clear purpose to much of the small farm activity, making evaluation difficult if not impossible. Those who control the use of public funds are reluctant to support proposals for increased activity without an adequate evaluation of present activities. Of perhaps even greater negative significance is an unrealistic expectation of what the agricultural science and education community can achieve. Projects have been initiated in an atmosphere of great missionary zeal where proclamations on objectives have not been sub- ject to the test of realism. Disappointment has been an all too ccmmon result of such undertakings even when positive results have been achieved. The rationale for assisting small-scale farmers should be based on four principles: 1. All farmers, regardless of size, should be assisted by the USDA land-grant college and university agricultural science and education system. Because of varying needs and types of farm- ing, no single method of assistance will suffice; programs must be developed to meet the unique needs of those who oper- ate small-scale farms as well as larger-scale farmers.
