draw); that the few conducting experimentation have not done so rigorously; that a folklore' ofthe supposed advantages ofPHS has developed; that communicationflows among NGOs regarding the outcome of PHS implementation have been inadequate, and that the rapid implementation of technologies easily visible from main roads implicitly encouraged by donors and by NGOs' own philosophy has led to premature introduction of unproven designs and management systems, and to a neglect of farmers' objectives and constraints. Potential Public Sector Contributions to Enhance NGO Effectiveness The weaknesses outlined above suggest three general ways in which government programmes and initiatives could enhance NGO effectiveness: Public Sector Commitment Towards the Rural Poor Whilst NGOs may grow in size and number to fill 'gaps' left by government, they will not be able to substitute for all the services that might normally be expected from government in all of the areas. Their efforts are likely to be more focused and defective where government makes a clear policy commitment to remove economic distortions against the rural sector and provides the physical infrastructure (roads; telecommunications) and human capital forma- tion which NGOs cannot provide in more than a piecemeal fashion. Policies of this kind are also a prerequisite to the establishment of inter-institutional links between NGOs and GOs. Easing Access to Resources and Information Controlled by the Public Sector In a recent meeting, Asian NGOs expressed their need, first, to access the skills, facilities, genetic material, and specialist knowledge of government services and, second, to have opportunity to influence government policies and strategies at the design stage. Large NGOs acting in consortium have occasionally persuaded government to cater to their needs, but simply to garner information on government plans, let alone influence them, is generally beyond the resources of smaller NGOs. To address such obstacles, NGO desks have been created in some Philippine line departments in order to elicit NGOs' views on draft plans and to cater to NGO enquiries (Ganapin, 1993).
