ASSESSING CHANGES IN SOIL EROSION RATES: A MARKOV CHAIN ANALYSIS

Rhonda K. Skaggs and Soumen Ghosh

Journal of Agricultural and Applied Economics, 1999, vol. 31, issue 03

Abstract: Markov chain analysis (one-step and long-run) is applied to the National Resources Inventory (NRI) database to evaluate changes in wind-based soil erosion rates over time. The research compares changes in soil erosion rates between NRI sample sites with and without applied conservation practices for a random sample of Great Plains counties. No significant differences between sites are found for half of the counties evaluated. The effectiveness and efficiency of conservation policies are thus questioned in light of these research results.
