Environmental impacts assessment may be some measures to offset the impact to an acceptable level or explore new solutions. The research was conducted with the aim of assessing the socio-economic, cultural, physical and ecological impacts of Kavar irrigation and drainage network in Fars Province (Iran). In this study, Environmental impacts assessment was undertaken by ICOLD matrix. The ICOLD matrix is one of the flexible methods that converted qualitative data into quantitative data. In this method, the effect of the project activities on the environmental components were assessed in two stages; project construction and operation based on physical, ecological, socio-economic and cultural aspects. The findings indicated that positive effects will be generally exerted on the region environment by establishing and operating irrigation and drainage network in Kavar plain. In other words, substantial positive impacts will be seen in the region consequently; such as improving the average level of aquifer, enhancement of agricultural wells, and agriculture development in the region. However, in order to alleviate the negative impacts of the projects processes, it is suggested that presented environmental training to farmers, collaborating and further communicating with other relevant organizations and institutions.

Bus rapid transit is an innovative, high capacity, lower cost public transit solution in metropolitan cities. Idea is to dedicate lanes for quick and efficient transport of passengers to their destinations. In the present investigation the environmental impact assessment of bus rapid transit in Tehran metropolitan city is brought out. For this purpose bus rapid transit Lane No. 10 is investigated. The bus rapid transit Lane No.10 is about 10 km in distance that moves up and down between Azadi and Simon Bolivar Squares. About 77500 passengers using 50 buses are transited per day in lane No. 10. These 50 buses cover a distance of 9600 km/day. The results of present study showed that about 6.5 million liters of fuel is saved annually. It should be pointed out that environmental costs are also reduced for about US$ 1.7 million/yr. The overall score of environmental impact assessment stands at +10 that is indicative of Lane No. 10 compatibility with the environmental considerations.
