Many of the human environmental problems arise from maladaptive behaviors and unstable patterns of life. The reason for the disappearance of forests is not beyond this discussion. One-sided management methods of natural resources and unfamiliar with the needs and traditional way of life of villagers and families living in the forest areas of northern Iran, unfavorable economic and social situation of villagers and low and unsustainable development in rural areas are effective factors in destroying Hyrcanian forests. One of the nature-friendly management methods that that has become popular in the world in the last two decades is "Ecovillage".The purpose of this study is to localize rural ecosystem criteria and indicators in developed countries and prioritize these indicators in rural ecosystems along the Darabkola forest with the aim of preventing the destruction and improper use of Natural areas, including forests and pastures.

In this study, the Delphi method was used to identify and localize the criteria and indicators of ecological, economic and socio-cultural evaluation. Entropy Shanon and TOPSIS techniques were also used to determine the weight and prioritization of these criteria and indicators.

The results showed that ecological criteria with 0.460 had the highest and socio-cultural and economic criteria with 0.375 and 0.165, respectively, had lower weights.

In general, the results of this study showed that attention to ecological category indicators has a higher priority than social and economic indicators. As a result, it is more important to pay attention to these indicators for decision making and management.

Forest logging prohibition is one of the most important challenges in the management of Hyrcanian forests that it has diffrent consequences. The purpose of this study is identifing, weighting and prioritizetion the positive and negative consequences of the forest logging prohibition from economic and social aspects in forests in the east of Mazandaran province (forests managed of the department of natural resources and watershed of Mazandaran province (Sari). The statistical population of the study consists of a group of 60 people including experts and specialists, faculty members specialized in this field and rural communities living in the margins of managed forests. In the study we used the Delphi method for identifing the consequences of the forest logging prohibition, the entropy technique used to calculate the weight of them and the preferences technique based on the similarity to the ideal solution (TOPSIS) used to prioritize them. The analysis of the research findings identified 6 positive and 17 negative consequences from economic and social aspects for the forest logging prohibition based on 55 questionnaires received.The results of consequences weighting showed that among the positive consequences, the consequences of increasing the economic values of forest environmental services and the tendency towards wood cultivation with weights 0.200573 and 0.200426 respectivly, and from the negative consequences, increasing wood smuggling 0.05163 and reducing employment 0.0513133 have the most weight. The results of prioritization of consequences showed that among the positive and negative consequences, changing the dependent management of wood to multiple management forest and increasing wood smuggling have the highest priority among other consequences. Also the results showed that in positive consequences, economic perspective and in negative consequences, social perspective gained more weight. Therefore, we are suggested that in order to implement the forest logging prohibition plan, programs considered for accurate, continuous monitoring and budget allocation for increaseing forest protection and reduce wood smuggling and create job opportunities by the government.

In an era of unprecedented industrialization and urbanization, sustainable forest management (including management and conservation measures) are particularly essential. In this context, the criteria and indicators are considered as means for defining, monitoring and assessment of forest sustainability. However, the existing database of research on such criteria and indicators in Iran is still limited. Hence, this study aims at defining a set of criteria and indicators in an example of Kalgachi local system, Chaharmahal-va-Bakhtiari province. This research was performed in several stages using different methods. In the first stage, socio-economic indicators of the Near East Process were prioritized by questionnaires to adapt the regional conditions. The indicators were further compared pair wise using further questioners. In the last step, a set of expert interviews, field studies, local community survey and document reviews in related organizations within the study area were conducted to determine the criteria and indicators. Based on the results, the finally-selected socio-economic indicators based on expert’s opinions and forest-dependent communities included the reduction in the number of interferences to forest areas, improvement of livelihood of forest-dependent communities, cooperation of local communities with equal rights (e.g. in number of groups and man/women share) and cooperation on agricultural development and conditions.

In this study، socioeconomic factors affecting poplar plantation development in North Khorasan Province in 2013-14 was analyzed using cross sectional data from 54 poplar plantation in 30 villages and was estimated by a linear regression analysis. The results obtained from correlation coefficient showed a positive relationship between poplar plantation and a number of factors including educational level، provision of free seedlings by the state، using low-interest bank loans، guaranteed purchase of wood by the government and attending in poplar cultivation courses offered by the state. In addition، the results of linear regression indicated significant differences amongst three qualitatively variables (including free seedlings by the government، low-interest loans and guaranteed purchase of wood) which also positively affect the amount poplar plantation.

Population Increase and cities expansion caused increase in energy consumption and negative effects on climate temperature changes and on physical and mental health of cities residents as well. One of the effective solutions is preservation and development of urban forestry (green space) which can retrieve partly, these negative effects. In order to investigate the urban forestry economy effects (green space), 384 questionnaires were distributed among people and the data were analyzed, using SPSS software. The results indicate that urban forestry has useful effects on energy consumption. Based on calculated coefficient of determination (R2), 56% of variation of depended variable (Urban forestry or green space) can be predicted and determined by tree variables (turn on air conditioner time, maximum of energy consumption and energy cost in hot season). Finally, a mathematical correlation between urban forestry and economical factors was developed. The correlation showed that development of urban forestry (green space) decreased the various costs
