Knowing and determining the water productivity is the first step to improve it. The aim of this research is to determine the water productivity of potato plants in hot, moderate and cold climates of Kermanshah province. In the mentioned climates, Qasr-e-Shirin, Kermanshah and Sonqor cities, which had the largest area under potato cultivation, were selected as the areas for conducting this research. For this purpose, 35 farms were selected under the conditions of farmers in 2021-2022. The total volume of irrigation water of each of the selected farms was measured during the growing season. Effective precipitation was determined using the USDA equation. The amount of water consumed by farms was also calculated from the total amount of irrigation water and effective precipitation. After harvesting the crop and determining the yield of potatoes by dividing the amount of yield by the amount of water consumed, the water productivity of the selected farms was determined. SPSS software and ANOVA analysis of variance were used for statistical analysis of the results. The results showed that the average volume of potato irrigation water in the sprinkler method in Qasr-e-Shirin, Kermanshah and Sonqor cities was 7507, 7186, and 6739 m3 ha-1, respectively, and their average water consumption was 8002, 7246, and 6783 m3 ha-1, respectively. The average yield of potatoes in these cities was 24100, 35500 and 36100 kg ha-1, respectively. Therefore, the average water productivity of potatoes in these cities was 3.4, 4.9 and 5.7 kg m-3, respectively. Therefore, the results showed that the water productivity of potatoes in Qasr-e-Shirin city is 30%, and 40% lower than in Kermanshah and Sonqor cities, respectively, and the most important reasons are the lower yield and the larger volume of irrigation water and potato water consumption in this city. Therefore, it is possible to increase yield and reduce water consumption and finally increase the water productivity of potato by managing agronomic and breeding, and training farmers in order to reduce water consumption in this city.

The present research was conducted with the aim of applying the theory of planned behavior in investigating the intention of farmers to use pressurized irrigation system. To achieve the goal of the research, the descriptive-correlation method based on the structural equation model was used. The statistical population included farmers in the central part of Baghmolek county (N=3005). The sample size was 343 people using Morgan's table and sampling was also done in a stratified method with proportional allocation. The instrument of data collection was a questionnaire, the validity of which was based on the opinion of the university faculty members and its reliability was through Cronbach's alpha, also, in order to determine the validity of the structure, the average variance extracted index (AVE) was also confirmed in determining the reliability of the model from the composite reliability index (CR), the homogeneity reliability index (Rho). The results of the structural equation model showed that the variables of attitude, subjective norms and perceived behavioral control predicted 76% of the changes in the variable of intention to use pressurized irrigation system. According to the findings of the structural equation analysis, the variable of knowledge predicted 87% of the changes of the variable of attitude towards the acceptance of pressure irrigation system. Since there is a significant relationship between the research constructs and the farmers' behavioral inclination towards using the pressure irrigation system.

The present study was conducted with the aim of investigating the effect of altruistic and Egoistic values on the attitude and intention of farmers in Kermanshah province to adapt to water shortage. In order to select farmers, a multi-stage cluster sampling method was used (n=380). The data was collected from the wheat farmers of Kermanshah province through a researcher-made questionnaire. The reliability and validity of the questionnaire was tested and confirmed. The conceptual model was analyzed using partial least squares structural equation modeling (PLS-SEM). The results showed that the variable of altruistic values had a positive and significant effect on the variables of attitude and intention to adapt, and the variable of egoistic values had a negative and significant effect on the variables of attitude and intention to adapt. Also, the attitude variable towards adapting to water scarcity had a positive and significant effect on the intention to adapt. In the present study, 39% of the variance of the attitude variable and 50.1% of the variance of the intention to adapt to water scarcity were explained.

A lack of adaptive capacities for climate change prevents poor farmers from diversifying agricultural production. Climate change adaptation strategies can reduce the production risk relating to unforeseen climatic shocks and increase farmers’ food, income, and livelihood security. This paper investigates date palm farmers’ adaptive capacities to adapt climate change strategies to reduce the date production risk. The study collected 300 farm-level micro-data of date palm farmers with the direct cooperation. The survey was conducted during periods between July and September of 2022. Date palm farmers’ adaptive capacities were estimated quantitatively by categorizing the farmers as high, moderate, and low-level adapters to climate change adaptation strategies. In this study, a Cobb–Douglas production function was used to measure the effects of farmers’ adaptive capacities on date production. The obtained results show that farmers are moderately adaptive in terms of adaptation strategies on climate change and the degree of adaptation capacities. Agronomic practices such as the quantity of fertilizer used, the amount of labor, the farm’s size, and extension contacts have a substantial impact on date production. This study recommends that a farmer more significantly adjusts to adaptation strategies on climate change to reduce date production. These strategies will help farmers to reduce the risk and produce higher quality date fruit. Consequently, date palm farmers should facilitate better extension services and change the present agronomic practice to attain a higher adaptation status. It can be very clearly seen that low adaptability results in lower date yields

According to factor analysis of the experts' views, extension methods to combat drought can be summarized in 4 categories, which are: visit tours, using extension publications, using information networks, using cooperatives, village municipality and councils' capacities.

Due to the adverse effects of conventional agriculture on human health and the environment, there has been a lot of emphasis at the global and national level to move towards sustainable agriculture. Knowing the attitudinal and behavioral status of farmers, as agents of this policy, is very important. In this descriptive-correlational research, the attitudes and behavior of farmers regarding sustainable agriculture were studied with an emphasis on plant conservation. Using multi-stage random sampling method and Cochran's formula, 300 farmers of Arak city were selected and studied. The validity of the research tool was confirmed by using the opinions of experts, and its reliability was also obtained by conducting a preliminary study and calculating Cronbach's alpha greater than 0.86 for composite indicators. The results showed that 86% of farmers had a neutral attitude and only 14% had a favorable attitude regarding sustainable agriculture. The correlation coefficient showed that farmers' behavior has a positive and significant relationship with the variables of attitude towards sustainability, level of education, area of rainfed agricultural land, area of integrated agricultural land, level of interest in integration, contact with agricultural experts, contact with agricultural machinery sales centers, visit to Extension farms, use of radio, neighboring farmers in the village and a negative and significant relationship with farmers' monthly income. Regression analysis also showed that Six variables including attitude, agricultural land area, monthly income, education level, receiving information from input sellers and interest in integrating farms explain 33.9% of the variance of farmers' behavior regarding sustainability.

By producing of healthy and organic agricultural products could be help the sustainability of the ecosystem and the health of society, but this bitter truth should be also accepted that organic and healthy farmers has been confronted with many obstacles for this production. Therefore, identifying the production of healthy and organic agricultural products deterrent barriers and its facilitating factors from farmers’ perspective is very important. The current qualitative research was conducted using the content analysis method to achieve this purpose. In this study, in order to collect data, in-depth and semi-structured interviews were conducted with 11 farmers in the area of healthy and organic production, and statistical samples were selected in a purposeful way and continued until the theoretical saturation point was reached. Instrument data collection were semi-structured and in-depth interviews with farmers who had the experience of organic agricultural or were a healthy product producer (n=11). Then Data collected were analyzed using MAXQDA Analytics Pro 2020 software. These Data were organized in three stages of open coding, categorization and abstraction. To evaluate the validity and reliability of this qualitative study, four criteria of Credibility, Transferability, Dependability and Confirm ability were used. The results showed that 55 percent of farmers with a healthy production certificate were men and 45 percent were women. Regarding the current situation of production in the province, 25 initial codes were identified in four main categories. The results of the analysis of interviews with farmers regarding deterrents showed that 57 initial codes identified in seven categories: economic and market, government-supportive, attitude-cultural, natural, productive and technical, research and development and education, legal and individual-professional were summarized. Also, 16 initial output codes related to promotional factors were extracted. According to the results of the research, it is suggested that the direction of the government's agricultural policies should be directed towards the environmental and social goals of producing healthy and organic products.

In this regard, six effective criteria along with 21 sub-criteria were considered. To determine the weight of criteria and sub-criteria, questionnaires based on pairwise comparisons were prepared and experts from Ministry of Agriculture Jihad of Guilan province were questioned to complete the questionnaires and the Expert Choice software was used to perform the calculations. According to the results, criteria of managerial challenges (0.368), fragmentation of land (0.229), lack of conversion and complementary industries and specialized and skilled human labor (0.155), resource limitation and land use change (0.126), low level of mechanization in the agricultural sector (0.076) and single crop cultivation and uncontrolled import of agricultural products (0.047) were ranked, respectively. Also inadequate use of inadequate resources and investments (0.157), failure to use supportive and credit policies (0.121) and non-payment of subsidies as a percentage of premiums to all insurers equally and irresponsible view of government and insurers on agricultural insurance (0.085), are three important sub-criteria with respect to the maximum weight obtained.

Sustainable use of water resources is now the challenge of the century, especially in arid and semi-arid countries. The use of pressurized irrigation systems improves the water productivity of plants if used properly. This study was to assess the educational needs assessment of agriculturalists with pressurized irrigation system with water scarcity adaptation. The three-dimensional model of Kauffman, Corrigan, and Johnson, and the Delphi method were used for the educational needs assessment of agriculturalists. The findings showed that agriculturalists' knowledge and skills in terms of "agriculturalists", "experts" and "trainer" were 3.11±1.26, 2.26±0.76, and 2.24±0.81, respectively for farmers and 3.69±1.1, 2.31±0.75, and 2.45±0.87 (out of 5 points), respectively for horticulturists. Knowledge of agriculturalists in most educational needs, especially from the point of view of experts and trainers, is below average (score 3). The most important educational needs based on three perspectives were "determination of irrigation time with new tools and technologies", "specific irrigation mode for each crop" "adaptation of farm management with irrigation system type" for farmers, and "water loss reduction in irrigation ponds", "specific irrigation mode for each crop" and "how to operate pressurized irrigation systems" for horticulturists. The results of this study showed the priorities of defining the headings and training courses for agriculturalists with a pressurized irrigation system. The findings also showed that agriculturalists are aware of the importance and necessity of education and that for effective education future research should focus on identifying educational practices appropriate to the climate, cultural, and social conditions.

Agriculture as the main source of livelihood for rural residents of the developing countries is inherently sensitive to climate variability and change. Among different climatic events, drought is frequently identified as a major threat to agricultural. In order to reduce the negative impacts of drought on livelihoods, increasing the resilience of farmers is necessary. Improving the sustainable livelihoods of rural people has received growing attention during last decades and is one of the main goals of sustainable rural development. Therefore, the purpose of this study is to evaluate and analyze the resilience of farmers and provide livelihood strategies in the central part of Shazand County based on random sampling of 12 villages. The aforementioned villages to assess the resilience, the four dimensions of economic, social, and institutional infrastructure based environmental were used based on the sustainable livelihood framework, was used. The findings of the study showed that the farmers' resilience to drought conditions is in unsustainable economic and institutional dimensions and in the environmental and social indicators of a stable situation. The results of cluster analysis method, five livelihood strategies for compensating and resilient farmers against drought including the first strategy for deep-seated agriculture and increasing productivity, second, third and fourth strategies for diversification into non-agricultural and domestic activities and ultimately the strategy. Fifth, based on the desire to migrate, was identified and presented.

So that they can predict 40% of variance of the dependent variable of the research (sustainable environmental operations).

Incorrect use of chemical fertilizers has had significant consequences on the quality of the environment as well as human welfare. Therefore, limiting its release may be achieved by improving fertilizer management. In this regard, farmers, as the main actors and decision makers in the agricultural sector, will have the task of limiting the use of nitrogen fertilizer and thereby reducing its effects. Therefore, understanding farmers' actions is essential to identify the types of policies that can effectively promote social and technological change. Because developing behavior and promoting the knowledge of environmentalists is an important issue for policymakers, advocates of green businesses and other stakeholders interested in adopting and enhancing environmental protection behavior. Therefore, the purpose of this study was to investigate the behavior of farmers in Ramshir region regarding nitrogen fertilizer application and its determinants factors. To achieve the research goal, two theories of normative activation and environmental behavior prediction were used. The data were collected through survey technique using a structured questionnaire. Validity of the questionnaire was confirmed by faculty members of Agricultural Sciences and Natural Resources University of Khuzestan. Reliability of questionnaire was confirmed by Cronbach's alpha test. The sampling method was based on systematic random sampling. Based on the Kerjesi and Morgan table, a sample of 200 farmers was selected among farmers who had received fertilizer from Ramshir Agricultural Jihad Management Organization in year 2018- 2019. The results of the study showed that in the normative activation theory, effectiveness, responsibility, awareness of consequences and subjective norms explain ethical norm variable and the behavior of farmers is significantly explained by the ethical norm variable. In the environmental behavior prediction theory, the variable of intentions was explained by awareness of action strategies and personality factors. Based on the results of the research, suggestions were presented to improve the implementation of the policies in order to better use nitrogen fertilizers.
