The need for extension action programmes
I am not very sure how to interpret your question. In the United States, we use the program evaluation and local program planning to decide what programs are needing to be develop. Local guidance committees are used to identify local community needs. These local needs are used to determine needs in each of the 50 states and the state needs are used to develop the national programming efforts.
For the results, look at this web page: http://www.csrees.usda.gov/nea/programs.html
