Résumé partiel
Watershed degradation due to soil erosion is considered a major challenge in Iran, despite the introduction of several projects aimed at mitigating this environmental menace. Issues related to technical and social complexities of the watershed projects are difficult to evaluate, in spite of lessons learned from past experiences. In order to address such challenges, it is essential to assess fundamental social and technical issues involved. Previous attempts using quantitative and qualitative evaluation methods separately had their strengths and weaknesses. Addressing this issue requires an integrated watershed management approach. This study presents an integrated model using technical and social approaches for evaluation of the Kushk-Abad Basin (KAB) watershed projects in Iran. The study was conducted within an 85 km2 zone of the KAB, which is a sub-basin of the larger Kardeh dam catchment. The study is aimed at evaluating socio-demographic and technical factors affecting KAB Watershed Management Program (WMP) taking into consideration pre, during and post project scenarios, particularly on the land treatment efforts initiated by the Watershed Management Organization of Iran. The social evaluation study was designed to determine the factors that affect variation of level of participation in WMP in Iran. In this regard, a conceptual model was developed to : 1) identify characteristics that lead to the participation in WMP, and 2) determine the factors that affect variation of level of participation. In each of the selected three villages within the KAB locality, 200 individuals were randomly interviewed using a structured questionnaire for assessment of their socio-economic characteristics and participation in the various watershed management programs. The sample size used was based on the Cochran formula with a confidence level of 0.05. The respondents’ level of knowledge, attitude, expectation and satisfaction of previous watershed programs were examined against the level of participation. On the other aspect, the technical evaluation study examined watershed management and bio-engineering processes of structures through measures implemented during operations. Based on a series of statistical analysis from the use of chi-square, factor analysis and regression, the results of the social evaluation study suggested significant relationship between knowledge, expectation and attitude on WMP with participation among the villagers in KAB. The relationship between age, household size, number of sons after 15 years, size of irrigated and rain-fed lands were positively correlated with watershed participation.
