In summary, a developing country must assess several factors in deciding whether to transfer in research results from another country or from an international center. Agricultural research is a long-term investment. Research takes time, adoption of new technologies takes time, and research results eventually depreciate as insects and diseases evolve, the economic environment changes, and so on. Developing countries often attempt to bring in research results from other countries during the early stages of development in order to shorten this process and meet critical needs. Perhaps a 1 percent productivity growth rate can be accomplished through a relatively simple transfer process, though
such productivity will depend on the conditions previously mentioned.12 However, the requirements of modern rates of growth in food demand,often in the 3 to 6 percentage range, require the coexistence of at least some indigenous agricultural research capacity, and this capacity may be a combination of public and private.
