1. INTRODUCTION
Natural resource degradation especially soil erosion
is one of the most important problems all over the world
especially in Iran. Although, many projects in Iran have
been conducted over several decades including watershed
and range management projects. But, after more than 40
years, it seems that these projects could not reach to their
objectives, because of increasing amount of the
degradation and erosion processes (Mohseni et al., 2008).
In other hand people participation can be important in
successes of watershed management. Therefore, it is
necessary to assess these projects to recognize the reason
of their failure.
