Abstract

Different countries have been affected harmfully by drought as a natural hazard affected by harmfully. Iran has been subjected by consequences of harmful drought consequences. It is argued that rural households due to their high level of dependency on agricultural economy are not well equipped to deal with this multi-dementia phenomenon. This study aims to evaluate the degree of the rural household’s potential regarding adopting drought. Statistical society composed of ٣٣٢٩ farmer households resided in Drudframan in Kermanshah County out of which ١٧٢ assigned as our sample. This study suggests that households are classified into low-median and high regarding their level of adoption to drought. It further suggests that out of ١٤ studied villages, the residents of Moradabad, Bozorgdar sofla, possess the highest level of adoption with respect to drought. This in turn demands the involvement of drought planners of the province in mitigation plans of the phenomena taking into consideration its causes and consequences, farmers and their vulnerability potential regarding adoption to droughtlevel.

Introduction:
Draught is being considered as a climatic reality in arid and semi-arid regions such as Iran. Drought is capable of generating drastic impacts over water and soil resources, vegetation, animals and human beings. Water is a prominent factor as far as agricultural product is concerned specially in arid zones. Draught and its impact on water resources will bear unpleasant consequences namely for rural settlers whose livelihood depend on agricultural pursuit.it is argued that draught will lead to set of complicated environmental, economic and social impacts. Taking into account the frequency of its occurrence, extent and complexity it demands more attention regarding the identification of its impacts. There is not a rigid agreement regarding the definition of this phenomenon. This in turn will lead to some complexities with respect to the assessment of draught. There exist different measures for simulation of rainfalls, water surface run offs as well as other water resources. This helps to come up with clear images of climatic and hydrological draught. There exist different indices for measuring rainfall deviation from average including SPI and SDI. Lack of sufficient knowledge’s and understanding with respect to impacts is being considered as other complexity regarding the inter partition of draught. In spite of high occurrence and the great magnitude of draught, little attention paid to explanation of its impacts. According to the relevant statistics 22 % of economic damages resulted from natural hazard is associated with draught. 33 % of people are being affected by draught. In the countries based on agriculture economy, impact of draught could be evidenced by low surface water supply and underground waters. This in turn, is responsible for reduction in water supply as well as water quality, low level of crops production, productivity, and crisis regarding food an increase in livestock death. On the other hand, drought impacts could exemplify it in economic, social and environmental impacts including decrease in household incomes, reduction in substitute income resources, and increase in both hours and volume work, conflict regarding water utilization, food deficiencies, malnutrition, low level of health, and accessibility to sanitation services, low education possibilities, unequal access to financial supports. Moreover, increase in rural migration, lack of power, low life quality, destruction of natural habitats, low productivity of forests and pastures, increase in temperature as well as evaporation, low soil productivity, reduction in water resources, pollution, increase in fire incidence are among other impacts. Variation in spatial and temporal scale of its draught turns it into a very unique phenomenon. It is argued that draught impacts are result of natural interaction (low rainfall) and the way respondents respond. Most of draught studies predominantly are concentrated at national level. However, well documented information regarding draught impacts is nonexistence. This study aims to investigate draught impacts and its influential responsible factors at rural household level.
Methodology:
The research method is based on descriptive-analytical method. Needed data were obtained through survey in Dodangeh Behbahan. It is located in north-western part of Behbahan. Statistical society includes all of peasant households reside in village with 20 and over households (2865). Cochran formula was used in order to determine the sample size. This led to extraction of 339 peasants which were interviewed. Its viability was determined using relevant expert’s viewpoints. This study further demands application of standard rainfall indices in order to determine the magnitude and continuity of climatic and hydrologic draughts.
Conclusion:
Current wide spread and server drought exerted considerable damage in Dodangeh rural economy. Efforts toward mitigation of economic impacts of draught require the identification of characteristics of this phenomenon. This study suggests that the assessment and evaluation of intensity and continuity of draught would well be done through application of standard rainfall and surface run offs. It further indicates that drought as a complex phenomenon is capable of increasing the vulnerability of the rural households. Certain economic impacts of draught are unexpected. Contrary to other draught studies results, agricultural lands have not been shirked. This has something to do with lack of due information regarding moisture status. The identification of draught risk is prerequisite for mitigation of farmer’s vulnerabilities. This in turn demands the application of sound and influential drought management based on information and relevant knowledge. In as much as agriculture is the most prominent livelihood in the region thus providing non-agricultural occupations help to reduce the level of vulnerability. Therefore, policies and measures for generating non-agricultural jobs in regions with high subjectivity to draught are highly recommended. According to the finding of this study, selling livestock’s and agricultural land are among some strategies for combating against draught taken by farmers. It is recommended that vulnerability of farmers, long run impacts and management issue all need to be considered. Moreover, improvement in extension services through provision of computable mechanism suited with draught condition assists mitigation of draught unpleasant impacts based on regression analysis, the amount of farmers debts, financial ability, age and households expenditure are the major variables as far as households vulnerability to draught is concerned. Furthermore, provision of financial and social support system is highly suggested.

Introduction
Drought is a natural disaster resulting in many damages to human life and natural ecosystems which is different from other kinds of disasters such as flood, hurricanes and earthquakes. As a result of this phenomenon, the level of surface water and ground water decrease dramatically and it is followed by various negative impacts on all aspects of villagers' life especially on economic aspect and agriculture structure. Frequent droughts result in more and more vulnerability of rural societies for facing present droughts, in a way that in some societies the basic challenge for many vulnerable households regarding the drought is survival. The economy of studied villages in Sirvan and Chardavol counties is dependent on agriculture activity. In the past years and before the occurrence of drought, these two counties were considered as a focal point for rice cultivation in Ilam province. In recent years, agriculture section is affected severely and water lands turned to be arid during the year because of climate changes and following that the occurrence of drought and its impacts on water resources, such as drying of seasonal and permanent rivers (Chardavol River) or decrease in agriculture water in the studied counties. According to the agricultural statistics released by Agriculture Organization of Ilam province, proportion of area under irrigated cereals as the dominant cultivation in two counties, Sirvan and Chardavol, in 74-75 crop year was 1530 and 6124 hectare respectively which has been decreased to 35 and 830 hectare in 90-91 crop year. These changes result in many problems in social and economic structure of rural districts in these counties. These problems in the studied rural societies are increase in unemployment, decrease in agricultural productions, decrease in income level and saving of households, increase of fake jobs. So, according to the necessity and importance of the issue, this survey aims to study economic impacts of drought on rural districts which are dependent on agriculture activities in Sirvan and Chardavol in order to answer the question that "What are the impacts of drought on economy of rural districts which are dependent on agriculture activities in Sirvan and Chardavol?"
Methodology
This survey is a descriptive- analytic one. The population includes all the farmers of Sirvan and Chardavol counties (N= 8099) and regarding the condition of the studied society, we used multistage hierarchical sampling method. Therefore, after determining the samples by using Cochran's Formula which was calculated 367 people, we determined the portion of each rural district and available village out of samples using multi-stage hierarchical sampling method and according to portion principle for each county's portion (103 people from Sirvan county and 264 people from Chardavol). Therefore, after determining the samples by using Cochran's Formula which was calculated 367 people, we determined the portion of each rural district and available villages out of samples using multi-stage hierarchical sampling method and according to portion principle for each county's portion (103 people from Sirvan county and 264 people from Chardavol). Questionnaires were the data collection tools in this survey. The questionnaires are divided to two parts: the first part includes questions about personal and social characteristics of the farmers such as age, sex, education, and their agriculture activities' experiences, water resources before and after drought, the amount and the type of owned land. Second part includes items in the case of drought impacts on economy of rural districts. Since the target villages are dependent on agriculture activities and farming, therefore, the resulted structural and functional impacts of drought on agriculture section such as areas under agriculture production, production, the process of planting and harvesting the crops, income and farming costs, investment and savings by farmers, employment in agriculture section and the number of employees are considered as indicators of drought impacts on economy of rural districts and these items have been questioned. The validity ofdata collection tool was confirmed by experts. Its stability has been achieved by performing pretest and calculation of Alfa Cronbach (0.797). To analysis the data, descriptive statistics and inferential statistics have been used including factor analysis. To assess suitability of the data by factor analysis, KMO and Bartlett test have been used. All the statistical calculations in this study have been done by SPSS version 20 for windows. Sirvan and Chardavol counties are located in Ilam province in the west of Iran. Chardavol County is divided to two districts; 5 rural districts and two cities; Sirvan County has one district, three rural districts and a city; according to 1390 census, Chardavol County’s population is 55225 and the rural population is 37981. Sirvan population is 16948 and its rural population is 13047. Economic structure of these counties is dependent on agriculture and their major water resources are Chardavol River and Simereh River which are almost dry because of recent drought and also the amount of water in Simireh River in two stations, Halilan and Sazbon, decreased up to 90 and 82 percent respectively in 2007-2008 water year.
Discussion and Conclusion
Drought is one of the most persistent and most harmful natural disaster regarding the economy of the region which not only affect the agriculture quickly and directly but also it is followed by indirect and harmful impacts as a result of disorder in natural growth of agricultural productions. The results of factor analysis showed that the recent drought resulted in negative impacts on the economy of the rural districts in two counties, Sirvan and Chardavol. Drought impacts on rural districts in Sirvan County are four impacts including: decrease in production, increase in farmers' debts, poverty and change in approaches to agriculture. The results of factor analysis in Chardavol county shows that many changes happened in the economy of rural districts of this region too because of the occurrence of drought including economic crisis, poverty, change in approaches to agriculture and the debt crisis. According to the obtained results, in Sirvan County, the first and the most important impact of drought on economy of villages which are dependent on agriculture activity is decrease in production.

Abstract

Introduction
For decades, various policy initiatives have been planned to achieve food security. However, the number of malnourished people is growing, especially in rural areas of developing countries. Due to the increase of extreme weather events, such as droughts, and significant depletion of water resources, achieving food security is not an easy task. Therefore, an investigation of rural households’ food security in drought prone areas is of great concern. On the other hand, it has been estimated that at least one third of the produced food would be wasted and half of the food waste originates at household level. However, considerable gaps exist in our understanding of how drought incidents affect the food waste management behaviors of farm families. Thus, addressing the factors influencing household’ food waste reduction efforts is crucial.
 
Methodology
In order to investigate food security and food waste control pattern of the farm families under drought a survey study was implemented on eastern regions of Fars province (i.e.
Kherameh County). Kherameh has suffered from 9 continuous years of meteorological and hydrological droughts. Farm families of Kherameh County were the target population. A stratified random sampling technique was used to select a sample of families who suffered from drought. The formula of Scheaffer et al. (2012) was used to determine the sample size (n= 219). Food security questionnaire which was developed by the United States Department of Agriculture was applied to investigate food security of farm families under drought. Also, household-level food waste questionnaire (van Harpen et al., 2016) was used to assess food waste behaviors of farm families during drought. Moreover, a questionnaire was developed to explore the main determinants of food security and food waste control under drought. Its face validity was confirmed by panel of experts. A pilot study was also conducted to evaluate the instrument.
 
Result and discussion
The findings revealed four different food security groups including 1) food secure (24.6%), 2) food insecure without hunger (22.9%), 3) food insecure with moderate hunger (23.7%) and 4) food insecure with extreme hunger (28.8%). The regression analysis was conducted to determine drivers of food security under drought. The results indicated that the specified variables explained 62% of the total variance in food security. The standardized regression coefficients illustrated that income was the main predictor of farm families’ food security. Families with higher income loss had more problems ensuring food security than the smaller ones. The results indicated that crop yield played an important role in determining food security. It suggested that farm families who experienced crop yield loss consumed lower amounts of food than usual. On the basis of the findings, food prices had a significant effect on food security of farm families. This implies that the cost of food was the major constraint and the majority of food insecure families had to lessen their food quantity and quality at a survival level. The results revealed that employment ratio, water scarcity and financial capital had important influences on food security, too.
The findings illustrated that drought stimulated food waste control. So that, food insecure families with moderate and extreme hunger had significantly reduced their food wastes. Moreover, food waste was significantly related to bread, rice, fresh vegetables and fresh fruit. This is while dairy and meat products’ waste were negligible. Analysis of the Bayesian network and partial least squares (PLS) path model illustrated that attitude exerted the maximum influence on the food waste control. Previous studies confirmed a positive effect of attitude on the food waste control behavior. The results revealed that income was negatively associated with food waste control behavior. Farm families who attempted to develop off-farm income sources and those who earned more money from agriculture were less likely to reduce food waste. Moreover, food waste control of farm families was significantly influenced by perceived food accessibility. This implies that higher access to food supply centers reduces the probability of food waste management. Also, findings illustrated that perceived food quality was associated with food waste control behavior. This shows that food quality was believed to be effective in reducing the food wastes. The results revealed that water scarcity, food prices and knowledge were associated with food waste control behavior, too. Overall, the model explained 34% of the variance in food waste control.
To ensure food security and minimize food waste under drought conditions, development of climate smart agriculture that allow increasing food production while using fewer water resources, promoting drought-risk reduction solutions and knowledge and information systems, and enhancing social, financial and human capitals are imperative.
