Yazd province because of cultural and historical background of the distant past always had known as ambitious and hard-working people. Manifesting multiple efforts of these people is seen in water harvesting. In Yazd province, background issues such as evaluation and assessment of water, ownership and agricultural water share refers to the distant past which has been changes over time in type and form. The purpose of this article, meanwhile a short review of management method and operation of water with a focus on Mirab, the evolution of ownership, irrigation circuit changes over time and changes in water price has been paid. Research methodology is single-type reticulum (monographic). Location research has been Chrkhab village of Yazd. Irrigation cycle of village has changed in four stages to the final cycle of water from 16 days to 21 days and 20 hours has become at present. Now, 53 Owner of the well are operating. In this study, according to the classification made, those of their right of water irrigation period were less than one hour (small landowners). This group, forming the highest frequency, equivalent of 33/6 percent was. According to the results, in extent of water right distribution between owners and various whiskers, the owners try to allocate more shares for them in order to play higher roles in the rural society. Study of the current water price changes for fifty years shows, the price of general inflation society has not follow. In this review the current water price increase rate (growth rate), 0/12 percent obtained.

Sistan plain is affected by desertification and this phenomenon has serious impacts on roads and socio- economic activities of local people of this region. The main purpose of this study is estimating the current and potential desertification intensity of Niatak region of Sistan based on MICD method. That, through it the working units of this region were prepared as the base map for evaluating to consider the factors and indices by geomorphology method. Also, in order to prepare the desertification intensity condition for both current and potential situations of this region, the desertification intensity of various applications was determined and relative plans to current and potential desertification of each land use were prepared after evaluating wind erosion indices and accumulating their scores for each working unit based on reference tables. The results showed that in this region the desertification potential consists of medium (III), intensive (IV) and very intensive (V) classes, while current desertification condition includes low (II), medium (III) and intensive (IV) classes of desertification intensity, respectively. These variations were resulted by wind erosion control activities over recent years.
