The present study aims to analyze farmers' perceptions of drought management solutions in small-scale farming units. The statistical population included all small-scale farmers in Isfahan province (166030 people) who were exposed to drought conditions. Using Morgan table, the sample size was determined by stratified proportionate sampling method of 394 people and the data collection tool was a researcher-made questionnaire. The results showed that the most important solutions used by farmers for drought management are "increasing information about drought and ways to deal with it", "better management of agricultural water", "timely irrigation", "planting windbreaks around" "Farms like poplar" and "seasonal migration to the surrounding areas for income." In order to categorize these solutions, factor analysis was used and a total of 5 factors such as irrigation management and moisture conservation solution; proper management of agricultural operations; household economy optimization solution; communication and information strengthening solution and “Social affairs adjustment solutions” were identified and named. The extracted factors explained 52.852% of the total variance changes, and at the end, based on the research findings, suggestions for increasing the adaptability of by small-scale farmers to climate change and drought were presented.

While Agricultural engineering, technical and consulting companies have been purposed as a mechanism for developing agriculture sector and increasing employment opportunities for agricultural graduates; providing sustainable qualitative services for farmers and income for their members is dependent on their competitiveness and so developing entrepreneurship in them.

Using a twostage sampling method, 102 people were selected from 500 organization members. Data was collected through a questionnaire the validity of which was confirmed by a panel of experts. The reliability of the study was assessed through Cronbach’s-Alpha which was 0.89. Findings revealed that, the instability in policies on agricultural sector, loan taking out cumbersome laws, lack of capital and cash flow, lack of security for investing in agricultural sector and lack of attention to agriculture sector by government were most important variables.

Continuing growth in human population and consumptionmeans that the global demand for food will increase for at least another 40 years and that the world needs 70-100% more food by 2050. Environmental issues such as climate change، depletion of naturalresources and biodiversity loss increasingly threaten the welfare ofhuman civilization. Confronting these threats requires، among otherthings، behavioral changes in citizens، governments and companies. Farmers and other producers are responding to consumer concerns about pesticides by creating new marketing opportunities for products grown with environmentally sound practices. Environmental economists are increasingly interested in better understanding of how people cognitively organize their beliefs and attitudes towards environmental change in order to identify key motives and barriers that stimulate or prevent action. The purpose of the presentinvestigation is to evaluate the consumers’ preferences and factors affecting their choice for conventional، healthy and organic cucumbers in Isfahan، Iran.

Data were collected on a sample of 230consumers in 2013 by using the proportionate stratification samplingmethod through face-to-face interviews based on a comprehensive structured questionnaire. Before the survey، the reliability and validity of the questionnaire were initially evaluated in a pre-test study، respectively، by using Cronbach’s alpha coefficient and Kaiser-Meyer-Olkin (KMO) criteria. Individual preferences were uncovered in choice experiment method (CEM) by a contingent ranking experiment. In a contingent ranking experiment، respondents are required to rank a set of alternative options، characterized by a number of attributes، which are offered at different levels across the options. Data were analyzed by multinomial logit models. The approach consists of modeling utility، that isto say the net benefit a consumer obtains from selecting a specificproduct in a choice situation. Determining and arranging selected sets based on a review of studies and theoretical basis design scenarios of the experiment method، includes environmental characteristics، taste، appearance، price، duration of storage، the disease and the long-term complications.

Most of the respondents were female، with average age of 41. 6 years، academic education level (39. 5%) and the average monthly income of 9،760 thousand Rials. The results show that 77. 1%، 12. 4% and 10. 1% of consumers، respectively selected the healthy، organic and conventional crops as a first choice. Moreover، the consumer''s awareness towards healthy food products is low. According to the logistic regression results، the most important factors affecting the consumers'' healthier choices are income، consumer knowledge about the characteristics of healthy and organic crops، the level of consumer’s attitudes toward the importance of environmental protection and human health and having an elderly or sick member in the household. On the other hand، healthy shopping concern، age، gender، employment status and education have no significant impact on the consumer’s selection. In other words، the likelihood of choosing healthy and organic products is more in people who care about their health and nutritional status، as well as with more health consciousness، environmental concerns and knowledge regarding the risks of pesticides and characteristics of free of pesticide fruit and vegetables.

There is no difference between academic and non-academic respondent’s preferences for healthy crops، because of no general academic courses on the importance of environmental protection، healthy shopping، production and consumption of healthy and organic products in Iran''seducationalsystem. Moreover، attitude and awareness play fundamental rolesin consumers'' preferences. Willingness to pay for healthy food products in women is observed to be more than men. This could be due to the fact that housewives have more leisure time than men to make themselves aware. Also in most families buying and cooking raw materials is one of women''s responsibilities which enables them to be more cautious in selecting foods. Knowing the characteristics of healthy and organic cropsis one of the most important factors in choosing and purchasing these products. Since the elderly and ill people need more feeding care and have less resistance to harmful additives and preservatives in food products، their families are more willing to buy free of chemicals fruits and vegetables. Promoting the consumers awareness toward the benefits of healthy products could change their attitude about the importance of maintaining health and subsequently improve public health and the environment. Furthermore، it is necessary to adopt thestandardsin the process of healthy crop production and to monitor andto strengthenthe marketing system of healthy products such as guaranteeing labeling and appropriatepackaging.

This paper aims to determine comparative advantage and competitiveness of crops in Isfahan province in agricultural year of 2009-2010 by using policy analysis matrix method. Selected products are wheat، barley، lentil، peas، beans، corn، sunflower، cotton، sugar beet، and watermelon. The results based on DRC showed that Isfahan province had comparative advantage in irrigated wheat، irrigated barley، beans، corn، peas، lentil، sunflower، sugar beet، and watermelon. Results of Nominal Price Coefficient (NPC) showed that coefficients for irrigated and rain -fed wheat، barley، beans، corn، peas، and sunflower were less than 1 and for other crops were more than 1. This indicates that most of crops have not received needed support from government. In addition، the results showed that while farmers received support for tradable inputs from government، the effective price support coefficients for most of crops were less than one.
