A B S T R A C T Sustainability in horticulture products depends on economic, social and environmental factors. Knowing these factors' sustainability levels can be effective in formulating sustainable horticulture development strategies and their effect on the sustainable livelihood of the user family. Therefore, this research aims to analyze the sustainability of horticulture products and their role in the livelihood of the beneficiary households in the villages of the central part of Bandar Gaz city. The required information was collected through a researcher-made questionnaire, the validity of which was obtained based on the opinion of relevant experts and the reliability of which was obtained by calculating Cronbach's alpha coefficient of 0.89. The statistical population of this research includes garden operators in three villages of Eastern Gaz, Western Gaz and Val Afra, which was calculated using Cochran's formula as a sample size of 250. A random sampling method was used to select research samples. To measure the sustainability of garden products, 45 indicators were used, separated by economic, social, and environmental dimensions, and 53 indicators were used, separated by economic, social, human, and environmental dimensions, to measure the sustainable livelihood of the beneficiary household. According to the Spearman test, horticulture products' economic, social and environmental sustainability is effective in the sustainable livelihood of the user family. The Kruskal-Wallis test results indicate that the beneficiaries' sustainable livelihoods in the three studied villages have a significant difference up to the 99% confidence level. The results of the one-way independent variance analysis test on the cultivated area of three villages and horticulture income in three villages also stated a significant difference in these three factors up to the 99% level. Extended Abstract Introduction The most critical challenge in the world today is food security and providing essential human needs. The lack of balance between population growth and agricultural production has made developing countries face a serious challenge. sustainable agriculture is an approach that meets human needs without harming the environment and uses natural resources better. sustainable horticulture is a type of agriculture that is in the direction of human benefits, is more efficient in the use of resources, and is in balance with the environment. Horticulture activity in the category of sustainable agricultural development, considering its nature and the positive aspects that govern this activity, in case of proper management, is superior in terms of not disrupting the ecological balance or at least due to little damage compared to agriculture. In fact, the benefits that can be listed for horticultural activities in order to achieve sustainable agricultural development compared to agriculture are food supply and welfare facilities, storage and meeting the needs of other plants, growing crops under the shelter of trees, soil protection and green cover, air conditioning and increase of atmospheric precipitation, less consumption of chemical fertilizers and preservation of plant genetic resources. A sustainable livelihood strategy is one of the new strategies that can help the villagers' problems. The sustainable livelihood approach was proposed in the 1980s as a new approach to rural development to reduce and eradicate rural poverty. Livelihood is sustainable when it can withstand unexpected pressures and damages and restore itself and improve its capabilities and capital in the future without harming natural resources. The main problem of the research is, what is the state of sustainability of the garden products system in the central villages of Bandar Gaz city? We are also trying to find out what effect the sustainability of garden products can have on the sustainable livelihood of rural households. Bandar Gaz is one of the Golestan province's cities, located in the southeastern part of Gorgan. In terms of longitude and latitude, it is located between 53 degrees and 51 minutes to 54 degrees and 3 minutes of east longitude and 36 degrees and 39 minutes to 36 degrees and 49 minutes of north latitude. Bandar Gaz has a population of 20,742 people in 6,715 households, according to 2016.   Methodology This research is of applied type and descriptive-analytical and survey method, carried out in the 2018-2019 crop year. The main tools for data collection were questionnaires, observations and interviews. The statistical population of the research consists of 715 users of horticultural products. A random sampling method was exerted to select the samples, and 250 samples were selected based on Cochran's formula.   Results and discussion The Kruskal-Wallis test was exerted to investigate and compare the household's sustainable livelihood level using gardens in the studied villages so that the results show a significant difference of 99%, 95% and 90% in the variables. The results show that the level of sustainable livelihood is different in the three villages, so based on the results, the level of sustainability of horticultural products is also different in these three villages.   Conclusion The efficiency of horticultural work for support and investment in the village of East Gaz is more than the other two villages. The ability to buy housing, the amount of meeting health needs, the amount of willingness to migrate, and the amount of unemployed and employed people are more in West Gaz village. However, regarding the village's up-to-date architecture and the village houses' strength, there is a more favorable situation in the village of Eastern Gaz. The results of one-way analysis of variance ANOVA indicate a significant difference between the garden income of three villages among the examined components up to the 99% level.   Funding There is no funding support.   Authors’ Contribution The authors contributed equally to the conceptualization and writing of the article.

The concept of sustainable development was defined in 1987 by the World Commission on Environment and Development (The Brundtland Commission) for which it «meets the need of the present without compromising the ability of future generations to meet their own needs.» Sustainability is a concept and cannot be measured directly. Appropriate indicators must be selected to determine levels and duration of sustainability. The objective of this study is to evaluate selected criteria and indicators of agricultural sustainability (with emphasis on economics indicators) at the national level. A sustainable agriculture must sustain the economic viability of the farming operation. The 2007 Iran census indicated approximately 20 million or 31 percent of the population live on rural. This paper presents economics factors of agriculture sustainable development for the years 2003 and 2007. It has used four indicators of agriculture productions insurance, Non-farms income, Profit margin and production productivity (product in surface). The sustainability index suggests that Iran agriculture is only slightly sustainable. On the basis of the indicators analyzed above, the Iran agriculture (economics sustainability) tends towards slightly sustainable: insufficient agriculture productions insurance, low income farms, low stability of the indexes of per capita production and low investment rate of return.

Those who give their wealth for the satisfaction of God and his mental stability are like to the garden that is located on the stack. If fall rains thoroughly, its fruit will double and little rain is sufficient for it and Allah has knowledge of all the things you (Baghareh, 265). Because of Iran is mountainous and rugged and rainfall is Sporadic, Waste about 56% of rainfall Because of traditional irrigation. Iran's climate and topography, Is suitable for the development of gardens. Because of importance of providing water for fruit trees and limited water, are important, in Dryland systems using methods that exploit the maximum available rainfall naturally, are very important. Because there is limited rainfall and irrigation in dryland, one of the critical points in the garden management, is keep increasing of Soils water uptake. Therefore, the main purpose is to manage rainfall in this way, is evapotranspiration loss and increasing efficiency of water uptake by plant. More Scientific references in our country are books that translated from universities in Europe and America that Have a different climate conditions with our country. And not considering this issue has much damaged to agriculture industry of Iran. Whereas according to the Goran, as a universal reference and always updated, can reduce problem of sustainable agriculture. For example, according to the Quran can be established dry garden in steep places, with selecting the correct location cultivation, selection of species resistant or tolerant and drought (Olives, Figs, Grapes and Dried Fruits) and the optimum use of rainwater.

Throughout the history, water has acted as the most important factor for development. Also subsequent droughts makes the sustainable use of water an imperative in many regions, including Iran.The present study determines how sodo-economic, physical, institutional and human factors contribute to water losses in agriculture. The study revealed that unsustainable irrigation water management was more common among farmers aged between 40-60 who: 1) had not insured their crops, 2) did not own their water resources, and 3) have stated to be influenced by water management behavior of their neighboring farmers.The study also concluded that the policy of increasing water charges might not have a marked contribution to the promotion of sustainable water use.

In general, insurance is a form of risk management used to hedge against a contingent loss. agriculture insurance is a special line of property insurance applied to agricultural firms. As well as agriculture insurance is one of the most efficient ways of managing the risks inherent to farming. sustainable agriculture integrates three main goals-environmental health, economic profitability, and social and economic equity. agriculture insurance is one of sustainable agriculture economics dimension. The aim of the study is to analyze agriculture insurance of Iran. The report starts with the description of sustainable development definition and sustainable agriculture indexes. Than evaluate the performance of agriculture insurance deals during 2006-2007. Gardens and farms are highly vulnerable, because are low water resources and Iran is located on the desert region.The findings of this study show that implementation of agriculture insurance, risk of operating in this sector has reduced somewhat. Also a performed calculation shows that the farmers funds received has been able to produce only 10 percent of the product cost. Other results show that only 12 percent of the garden farm country s has been subject to insurance. So Iran agriculture is less stable in terms of agriculture insurance.

Agricultural sector as a most important food producer sector is not only a main consumer of energy, but also a main energy producer. Agricultural sector, which is expected to provide food for a country's population, is faced with resource constraints. So there should exist a balance between use of resources and level of production. In this study it was tried to use an index of efficiency, in a framework of fractional programming, to develop an efficient system of energy to be used in producing main crops, in Khorasan province, while maintaining sustainability. The required data were gathered from various institutions as well as from a sample of 1572farmerspickedup through a two stage random sampling method. In order to analyse the data, the sample of farmers was categorized into eight groups, using analysis of variance. Standard tables were applied to change various cropping activities into energy units. The results indicated that there is an inverse relationship between energy efficiency index and gross. margin, that is, by giving priority to energy optimization, and placing crops with higher efficiency in the cropping pattern gross margin decreases, and vice versa. Regarding energy efficiency index of crops it can be concluded that energy is being wasted in production of some crops such as tomatoes and melons and therefore threatening the sustainability of agriculture sector. On the other hand production of such crops as wheat, barely, lentil, sugar beet and potato do support sustainability.
