On some agricultural lands, the natural drainage is sufficient to maintain high productivity. However, many others require improvements in surface and subsurface drainage in order to optimize land productivity, wh ile maintaining the quality of soil resources. As time passes, drainage requirements may change because of changes in the general socio-economic conditions, such as input and output prices, and more intensive crop rotations. -

The need. It is the view of many familiar with the fish culture industry in Hungary that decision makers involved could employ economic analysis more stringently when allocating available resources amongst industry activities. However, the number of full time economists employed in the industry is low- and most persons concerned believe it is likely to remain so low. The consultant concluded, therefore, that the persons concerned will be unable to use economic analysis more effectively in the coming years unless a change is made in the manner in which economic analysis is carried out. The concultant recommends that a concerned effort be made to introduce, in a systematic manner, a system for economic analysis which minimizes - but does not eliminate - the role of the economist. Implication for system desig n. The system should, as far as possible, be of use also to people working in the fish culture industry, who do not have formal training in economics. Therefore it should (i) reduce the reliance on economists during the data collection and information generating phase (which must preceed all economic analysis); (ii) fit the needs of fish farm managers, manager of fish culture research and development activities, and, the needs of government planners and policy makers.
