Abstract
Due to the existence of fertile alluvial soil and more than one hundred aqueducts (Qanats), agriculture and horticulture were prosperous in the Borkhar plain, north of Isfahan during the Qajar period. Furthermore, its location on the Isfahan highway to the capital of government made it easy to export products to other regions. Accordingly, livelihood in the Borkhar plain was affected by agriculture and horticulture. The questions are: how was the exploitation and management of resources in the Borkhar during the Qajar period? What were the strategies of livelihood based on agriculture and horticulture in the Borkhar during that time? What were the characteristics of the architecture of gardens and farms in the Borkhar? Data were collected via documentary and field methods, and the research method is descriptive-analytical. Based on the archaeological data such as gardens with the irregular plan and vast gardens with the designed and regular plan, it can be concluded that the type of agriculture and horticulture in the Borkhar plain was subsistence agriculture and agribusiness. In the early Qajar era, subsistence agriculture was common in the Borkhar plain. But in the second half of the Qajar era, agribusiness became common in this region like in other parts of Iran. Therefore, the income of agribusiness was allocated to livelihood and biological needs in the second period. If historical sources are also studied through content analysis, the above two strategies of livelihood are concluded. There was subsistence agriculture in this plain, such as wheat, barley, watermelon, carrots, pomegranates, apples, legumes, turmeric, and beets, as well as commercial cultivation of melons and cotton. This agribusiness helped to strengthen economic power and livelihoods based on agricultural incomes.

Introduction
Livelihood means human assets, behaviors, and activities that determine the standard of living of an individual, family, or community (Ellis, 2000: 10). According to Chambers and Conway, livelihood also means the capabilities and necessary activities to survive and determine lifestyle (Chambers and Conway, 1992: I-II). The strategies of livelihood were developed in different communities to increase social welfare and public health (Gaillard et al., 2009: 120). These strategies were included agricultural and horticultural livelihood, animal husbandry, fisheries, industrial activities, road services, and trade. In this article, the architectural features of gardens and buildings related to agriculture in the Borkhar plain were explained. Then, the strategies of livelihood in this plain during the Qajar period were analyzed.
As the entrance passage of Isfahan from the north, Borkhar plain was a strategic area on the north-south communication route of the country. This plain was considered an agricultural and horticultural area on the periphery of Isfahan.
The questions are how was the exploitation of resources in the Borkhar during the Qajar period? What were the strategies of livelihood based on agriculture and horticulture in the Borkhar during that time? What were the characteristics of the architecture of gardens and farms in the Borkhar?
The importance of this research is that it recognizes the systems of management and exploitation of natural resources in the past, especially with an emphasis on the methods of achieving sustainable livelihoods based on the capabilities of the region. While today, some cities and villages in the region are facing serious risks in terms of conservation of natural resources and livelihood, due to incorrect policies in local and regional development and lack of attention to local capabilities.
Data were collected via documentary and field methods, and the research method is descriptive-analytical. Analyzes were performed by “content analysis” of historical sources and “spatial analysis” of architectural monuments related to horticulture and agriculture.

Exploitation and Resource Management in Borkhar 
Geologically, the Borkhar plain is an alluvial plain and its settlements were developed in these alluviums (Shafaqi, 2002: 97). These alluvial soils cause fertility in this plain. The fertility of the Borkhar plain on the one hand, and the rise of the landowners class in the Qajar period on the other, led to the division of ownership of agricultural lands and gardens between lords and large landowners. Accordingly, the number of lords increased and they gained higher social prestige during the Qajar period. In addition to building residential castles on their agricultural lands and gardens, the lords and employers hired several farmers and settled them to increase the production and use of the land (Amirhajloo et al., 2012b: 115). 
Despite the fertile soil, the amount of rainfall in Borkhar plain was low. Therefore, groundwater extraction methods were important and aqueducts were created in the plain for this reason. The remains of “Pang-khaneh” buildings as a place for the distribution of aqueduct water in the Borkhar plain are important. Factors affecting the water distribution of aqueducts in Borkhar plain were: the features of the place, the amount of water of aqueducts, the number of households using water resources, type of cultivation, and laws governing the region. Exceptionally, for private aqueducts located on lord’s farms, all aqueduct water belonged only to the landowner.

The Strategies of Horticulture and Agriculture Livelihood in Borkhar
If we want to analyze the livelihood strategies of horticulture and agriculture in the Borkhar plain, we must pay attention to “subsistence agriculture” and “Agribusiness”. Subsistence agriculture is a type of agriculture that aims to produce as much as the needs of the family, tribe, or village and does not pay attention to foreign markets and earnings (Mosher, 2008: 6). While Agribusiness means specialized cultivation, production over subsistence needs, and product sales in the various markets (Amini, 2016: 549). While from the middle of the Qajar era, especially from the time of Mohammad Shah and Nasser al-Din Shah, “Agribusiness” also became popular (Mansour Bakht, 2009: 123, 147). 
Archaeological evidence of the Qajar era in the Borkhar plain indicates both of the above farming strategies. Archaeological remains show the subsistence agriculture strategy in this period; For example, small enclosed gardens, scattered and irregular gardens with an organic plan on the periphery of the villages of Morchekhort, Gaz, Gorgab, Sin, Dormian, Zaman Abad, Dastgerd, Dolatabad, Dombi, and Margh. While there is other evidence that shows the strategy of Agribusiness in Borkhar in the Qajar era, such as regular lordly gardens with a pre-designed plan and residential spaces for lords and farmers, as well as castles of landlords.
The content analysis of Qajar sources also confirms the existence of the above two livelihood strategies in Borkhar. For example, crops such as wheat, barley, watermelon, carrots, pomegranates, apples, legumes, summer vegetables, turmeric, and beets were grown for local consumption. But crops such as melons and cotton were grown commercially and then exported.

Conclusion
Based on the archaeological data and historical sources, subsistence agriculture was common in the Borkhar plain during the early Qajar era. But in the second half of the Qajar era, agribusiness became common in this region like in other parts of Iran. Therefore the income of agribusiness was allocated to livelihood and biological needs in the second period. If historical sources are also studied through content analysis, the above two strategies of livelihood are concluded. There was subsistence agriculture of wheat, barley, watermelon, carrots, pomegranates, apples, legumes, turmeric, and beets in this plain, as well as commercial cultivation of melons and cotton. This agribusiness helped to strengthen economic power and livelihoods based on agricultural incomes.
