Item Impact of Soil and Water Conservation on Crop Productivity in the Highlands of Ethiopia(Addis Ababa University, 2011-11) Endalkachew, Tessema; Woldehana, Tassew (PhD)Soil degradation continues to be major threat of Ethiopian economy, since it is extremely dependent on agricultural sector, even though a number of soil and water conservation (SWC) methods were introduced and practiced. The major goal of this research was finding out the real impact of SWC on crop productivity in the highlands of Ethiopia. The study was undertaken by using a survey data collected by Environmental Economics Policy Forum for Ethiopia (EEPFE) in 2007 from two zones, East Gojam and South Wollo in Amhara Region. A total of 1760 households who has 5871plots were interviewed. In this research a non parametric estimation method, propensity score matching (PSM), and a parametric estimation method, endogenous switching regression methods were used. Based on the empirical works done it was not impossible to the study to conclude the average value of crop production from plots which adopt SWC is less than that of the plots which did not use the technology Key words: Ethiopia, soil and water conservation, propensity score matching, endogenous switching regression.
