Renewable natural resources are national capital and are of paramount importance in each country. Preservation and developing these resources is incumbent upon relevant institutions and all people especially the beneficiaries. In this regard, various approaches have been recommended for optimum use and sustainable preservation of natural resources especially rangelands among which co-management is highly emphasized. To pinpoint challenges and barriers before co-management, the integrated institution-beneficiaries network (institutions related to rangeland management and rangeland users) of Ghasr-e-Yaghoub village in Safashahr was analyzed applying social network analysis method. Results demonstrated that cohesion level among rangeland users and institutions related to rangeland and also network sustainability in the study area was moderate and Village Islamic Council and Jihad-e Keshavarzi (Agricultural Development Agency) were the two most influential institutions. In other words, they were core actors among all institutions. Therefore, reinforcement of cohesion among actors and recognizing key actors in different levels are necessary approaches for implementation of co-management action plan. Additionally, it helps natural resource managers for sustainable management of rangelands.

Development impact assessment is key to achieving a comprehensive planning aligned with landsustainability. In human and natural systems studies, changes can be simultaneously examined intwo different systems. The purpose of this paper is to understand the effects of dam construction onland prices and land use change in nearby villages of Taleghan Dam. Descriptive - qualitativestatistics were used in this research and library and field methods were used for collecting therequired information. In order to specify the land value of the four villages of the area of the damfor four decaes, based on the prices of the year 1390, the land vlue formula was applied. Also, TMsatellite images of 1379 and 1386 were used for pinpointing land use changes. The results of thesestudies indicate that dam construction in 1380s and 1390s increased land price significantly andchanges in land price affected upon land use changes in nearby villages of dam and the price of landin the Zydasht village overlooking the dam increased dramatically.Based on the results of thisresearch, it can be stated that the dynamics of the land use of the area was affected by land pricethat for achieving sustainability in the watershed, an effective law must be enforced to prevent landdegradation and control land prices.

Providing of landing use maps and detecting of land capacity are required to manage of natural resources and environment and planning of land use. On the other hand, it is necessary to detect of the human deriving forces affecting land use change. In this research, we selected Seyed mohaleh and Drasara villages in Tonekabon city. First, were provided the land use maps in 1987 and 2008 by using TM and IRS Satellite images. Second, were investigated the human deriving forces affecting land use change through survey methods. According to results of this research can state that had been destroyed much percents of forests and added residential and agricultural lands in two villages. The most important of land use changes in two villages related to the economic problems (low income) and the economic loss of agricultural activities. Recently, the most important deterrent forces of land use changes are the property market downturn and land price that can prevent of severe changes in land use through the implementation of efficient land use law and supporting of farmers and gardeners in this region. Moreover, the most important indicators in the intensification of land use changes are being a tourist area, increasing of land price and unemployment.
