The purpose of the present study was the simulation of climate change effects on groundwater resources in Iran by using the dynamic systems approach. The approach was performed through system dynamics modeling process including problem explanation, system description, model development, model testing, and the use of the model for policy analysis. The impact of the application of various exogenous scenarios including drought scenarios, management of water supply and population growth was assessed and the behavior of variables of water resources volume and per capita volume of renewable water of the Southern Khorasan province was simulated by Vensim software for the 2013-2041 period. Data were collected by referring to relevant organizations like South Khorasan Regional Water Organization, South Khorasan Agricultural Organization, and Statistical Center of Iran and the input data of the model were fed into the model in an Excel worksheet. The results showed that the water resource exploitation management scenario had a significant positive effect on the balance of aquifers of South Khorasan Province so that the balance of the province aquifers in the scenario of controlling water resources exploitation has been significantly different from the scenario of the lack of control of different drought in all the studied years. In addition, the results of examination of the province's renewable water showed that droughts have had a negative impact on the volume of renewable water of the province and droughts together with population growth have reduced the province per capita renewable water.

Rural innovative producing organizations can increase farmers' incomes and improve food security by providing services to farmers. The specific objectives of this paper were to identify the economic, social-cultural, infrastructural, political, educational, and technical requirements for innovations in rural institutions to improve food security of farmers in Mazandaran Province, Iran. The total population of this study was 113,141 farmers in Mazandaran Province and by using Cochran formula 216 were selected through cluster random sampling method. The Delphi method was used for qualitative part of analysis, which was done in a three-phase distribution of questionnaires and interviews with rice experts. For each of the requirements, items of interest were added and removed, and a table of items including the most points (to a maximum of70%) was extracted. A Bayesian analysis was used for by using AMOS16and SPSS16 software. Based on the results of Bayesian analysis the economic requirements had the greatest impact on establishing innovative rural institutions to improve food security of rice growers. It was also found out that socio-cultural, political, infrastructural, educational, and technical requirements, respectively could play an important role in helping rural institutions to enhance food security in rural areas.

This descriptive-analytical research aimed to investigate the effects of the olive value chain on the assets of olive orchard owners in Rudbar County with the sustainable livelihood approach by the library and field method using a questionnaire. The content and face validity of the questionnaire were confirmed by a panel of experts after revision, and its general reliability was estimated at 0.97 by Cronbach’s alpha. The study site was Rudbar County. The statistical population was composed of 5053 olive orchard owners out of whom 604 people were sampled based on Bartlett’s table. Data were analyzed using the SPSS and LISREL software packages. According to the applied LISREL, the main findings were as follows: P-VALUE =0.000001, NNFI=0.907, CFI=0.910, RMSEA=0.036 and X^2/df =1.51, IFI =0.910 and PGFI =0.768. Results revealed that out of these five resources, social capital was the strongest one affecting respondents’ livelihoods in the study area (λ=1.02). The results revealed that the fit of the measurement model is appropriate and acceptable. Also, it can be said that capital assets influence livelihood outcomes significantly and positively, so the livelihood level will increase with increasing capital assets. Manuscript profile
