Abstract
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.
