ABSTRACT
Despite all the research on dryland problems and the availability of techniques to assess the economic desirability of corrective pro grammes and projects, there may still be difficulties in formulating appropriate plans and policies. How should a donor agency, for example, best allocate funds to the alleviation of dryland problems? Projects can be evaluated and the best ones chosen, as discussed in preceding chapters, but the larger-scale economic and environ mental implications need to be addressed. Project planning does not answer the question of whether an optimal mix of policies has been selected to achieve the most effective results.
