adopted sensitive approaches. The agreement of NGOs concerned with agroforestry in South Nyanza District of Kenya to coordinate their action with local government offices is particularly noteworthy (Musyoka et al., 1991). What Can NGOs, Research Services and Funding Agencies Do? In many countries the potential exists for mutually-beneficial links between NGOs and public sector research and extension services, though numerous obstacles also exist, and paths towards closer links have to be charted carefully. Two forewarnings are essential: first, the prospects will vary widely among countries, according to the wider context of NGO-State relations and according to how far NGOs and Government share a common view of the future of the rural poor, and of strategies for achieving that future. Second, within countries there is a wide diversity of NGO types, and their relations with government will lie along a spectrum from outright hostility to willing collaboration. Recognition of this diversity is implicit in our continued use of the loosely positive term 'link' to describe potential modes of interaction between NGOs and GOs. 'Collaboration', by contrast implies a high degree of mutual interdependence. Linkages can be promoted by the following actions: i) Efforts by GOs to keep a small percentage of their budgets (whether from central government or from externally-assisted projects) 'unallocated' to allow for rapid response to NGO requests as they arise. Needs and opportunities for potentially productive interaction often occur unexpectedly: they cannot always be held over to the next financial year. Alternatively, a percentage of staff time might be kept unallocated, and NGOs provided with the resources by their funding agencies to contract GO staff. ii) GO and NGO staff can jointly participate in training courses (ideally led by a joint team) in the 'learning-by-doing', 'action-oriented' methods favoured by NGOs such as participatory rapid appraisal (for examples see the RRA Notes series published by the International Institute for Environment and Development). The relevance of these methods to individual GO staff will vary, but their capacity to consolidate farmer- oriented perspectives is important. iii) Efforts need to be made by NGOs to interact more fully with each other than hitherto. Interaction may begin with exchanges of information and joint meetings, perhaps extending in some cases to fully collaborative projects. Most countries are character- ised by large number of NGOs of varying size, and GOsmay find it easier to work through effective NGO networks.
