Presented in detail are the critical concerns, the state of technical and economic estimation method, and the data constraints attendant to the economic valuation of the environmental effects of soil erosion. It was started by motivating the study of economic assessment of environmental effects. Valuation efforts should be properly put in the content of improving resource pricing policy. In Part 2 the development context for upstream conservation activities was established in terms of their implications for downstream impact - especially on the food production program in general and on irrigation development in particular. In Part 3, a detailed exposition of the methodologies for estimating erosion: gross erosion from USLE-based [Universal Soil Loss Equation] approaches as the basis for on-site effects and reservoir sedimentation measurements as the basis for off-site effects. In Part 4, the economic model for determining the optimal erosion rate was presented, and it was suggested that changes in the specification of damage functions to conform to what is known from on-site economic effects of erosion. It was concluded (in Part 3), with a discussion of the private decision-making perspective that requires conservation benefits to be judged vs. perceived losses in upland production.
