Implementation can be at the farm/enterprise level or the national level and thus it varies considerably. The primary cost control is embedded in COSA’s policy of training local institutional partners. Costs depend primarily on the number of surveys required to achieve a representative sample. The other components are training, quality control in the field, data processing, cleaning, and final analysis. Once COSA is learned and implemented, subsequent measures, even for different crops, are expected to be relatively less expensive and can eventually even be applied independently at a co-op or firm level.
