Agenda 21 recommends that developing countries should be assisted by international support and funding agencies in upgrading the technical and managerial capacities of small entrepreneurs and the vocational skills of operatives and supervisors in the building materials industry, using a variety of training methods. These countries should also be assisted in developing programmes to encourage the use of non-waste and clean technologies through appropriate transfer of technology.
Techniques used to provide skills may include: ordering skills information, fashioning skills development models, re-vitalizing skills methodologies, transmitting skills directly, and establishing skills exchanges.
