* second, the rate at which these develop will inevitably depend partly on wider conditions such as the provision of rural education. But those associations of small farmers, processors, landless irrigators and landless livestock keepers which do emerge offer the prospect of facilitating direct links between researchers and the rural poor, and of strengthening the capacity of the latter for exerting a demand-pull on research agenda including, as noted above, representation on official bodies governing research resource allocations. * third, a less ambitious form of social organisation than that needed for the establish- ment of producers' associations is the formation of groups around specific tasks (seed production, irrigation, integrated pest management) where coordinated action is necessary. NGO's activities in this sphere need to be examined against wider issues of the most appropriate basis for the organisation of membership organizations. Nevertheless, some expansion of NGOs' actions in these areas is to be anticipated, and can usefully be encouraged by GOs, whose own record as 'social organizers' is weak. * fourth, NGOs are concerned to develop local capacities for experimentation which (depending on their philosophy) build solely on farmers' indigenous knowledge, or build both on this and on relevant 'outside' ideas. This strategy may contribute to rural advancement in its own right, and the capacity it creates may prove a useful independent source of innovations in the absence of useable technologies from GOs. Alternatively, given the capability and inclination of GOs to work with the rural poor, it will be a useful complement to what GOs can offer. Many of the arguments about emerging roles and interactions discussed in this paper suggest that key liaisons could be developed with NGOs in any efforts to develop these wider brokerage functions among GOs and to relate their work more closely to the needs of the rural poor. Viewed in this context, whilst macro-economic pressures to reduce the size of the public sector are bound to remain threatening, they might also, if handled skilfully, mark the beginnings of an opportunity for GOs to intensify dialogue with NGOs in order to explore some of the ways identified above of enhancing the effectiveness of their own work.
