Despite the lack of formal evaluations, success has been perceived by all types of projects: whether at the community-level, activities aiming at changes in legislation, and industry-supported activities. Such a positive evaluation is promising, however it also has to be weighed against identified limitations in project planning, evaluation and reporting. The issue is how to provide guidance to prospective projects to strengthen planning (including carrying out formative research), to build evaluation into the project or programme strategy, and to ascertain that the various factors for success are incorporated and monitored.
The lack of formal evaluation and of cost data meant that an analysis of the cost/benefit of different approaches could not be undertaken. This is an important area of work for future research, although the wide variations in socio-cultural contexts mean that inter-country comparisons should be made with caution.
