Introduction
Agriculture and its products play a crucial role in sustaining human life. The introduction of the green revolution has greatly enhanced agricultural productivity worldwide by providing irrigation water, introducing improved crop varieties, and utilizing inorganic fertilizers and pesticides. These technologies received substantial public support, leading to significant advancements in agricultural practices. However, the benefits of the green revolution were not equally distributed among all farmers. Large and medium-scale farmers, who had the financial means to afford inputs and equipment, reaped the highest rewards in terms of production and income. Additionally, the excessive use of inorganic fertilizers resulted in soil and water quality degradation, posing a threat to the sustainability of the economic and social progress achieved through the green revolution. Nevertheless, it remains uncertain whether these challenges also apply at the sub-national or provincial level. By evaluating the level of agricultural sustainability, analyzing the trends in agricultural development, and identifying potential threats, it becomes possible to formulate practical plans for improving sustainability within the agricultural sector. The aim of this study is to assess indicators related to economic, social, and environmental dimensions of agricultural sustainability at the provincial level in Iran.
Materials and Methods
The assessment of sustainability of agriculture requires determination of meaningful indicators covering economic, social and environmental dimensions. Selection of indicators used in this study was based on relevance of the indicators and availability of secondary data. To achieve the purpose, the latest available information of the statistics of the Ministry of Jihad Agriculture, the results of the labor force survey of the Statistics Center of Iran and the statistical yearbooks of different provinces were used. In terms of measuring environmental sustainability, indicators of crop diversification, use of organic and inorganic fertilizers and pesticides were selected. The specific indicators used for the analyses in the economic dimension were change in overall crop production (Quantum index of agricultural production) and stability of crop production. The stability of crop production refers to maintaining a certain minimum level of production or a steady increase in production as compared to the base year. The stability of production of major crops was analyzed using the Shapiro-Wilk (SW) normality test and one sample t-test. In the social dimension, indicators of rural labor employment and rural food security were used. Based mainly on secondary data, covering the period of 2005/06–2018/19, each dimension of sustainability was analyzed using selected indicators.
Results and Discussion
The analyses conducted in this study revealed several significant findings. Firstly, the majority of provinces in the country demonstrated a favorable situation in terms of crop diversification, as indicated by the Herfindahl index. This suggests a wide variety of crops being cultivated in these regions. However, there was a notable variation in the use of inorganic fertilizers per unit of land across the country. Furthermore, more than 60% of the country's soils were found to have less than one percent organic carbon, highlighting the need for optimal application and management of organic fertilizers, particularly in Golestan province. The study also identified a high rate of pesticide usage in the northern and southern provinces of the country, indicating potential concerns regarding pesticide management and environmental impact in these regions. Additionally, the analysis revealed either a consistent trend or a significant decrease in the Quantum index of agricultural production in most provinces. This suggests a potential stagnation or decline in agricultural productivity over time in these areas. Moreover, there was a significant decrease in the employment rate of the rural population in Chaharmahal and Bakhtiari province. This finding implies potential shifts in employment patterns and economic dynamics in rural areas. Lastly, the study highlighted the significant share of food expenses in the income of the rural population in Sistan and Balouchestan province, underscoring the importance of addressing food security and affordability challenges in this region. Overall, these findings provide valuable insights into the current state of agricultural sustainability and development at the provincial level in Iran.
Conclusion
Based on the findings of this research, it can be concluded that regional differences exist in agricultural sustainability within Iran. In light of this, it is recommended to develop effective regional agricultural policies that are based on local-level research. This approach would enable a comprehensive understanding of the environmental concerns and specific needs at both the local and provincial levels. Furthermore, it is suggested to revise the agricultural extension structure to incorporate need-based services, improve the dissemination of information, and provide farm-level trainings. This would ensure that farmers have access to the necessary resources and knowledge to enhance their agricultural practices. The study emphasizes the importance of maintaining a balance among the three tiers of agricultural sustainability. Merely focusing on improving one or two tiers would not be sufficient to ensure the overall sustainability of the agricultural sector. Therefore, effective interventions should address economic, social, and environmental aspects simultaneously. Specific interventions proposed in the study include the development of biological pest control methods, particularly for rice and tomatoes. Indirect subsidies for organic and biological fertilizers and pesticides are also recommended. Conservation and management of soil and water resources are crucial for stabilizing production. Additionally, diversification of income sources and livelihood options for smallholder farmers, especially in Sistan and Balouchestan and Kordistan provinces, is recommended to enhance their resilience and sustainability. By implementing these recommended interventions, it is anticipated that agricultural sustainability in Iran can be improved, ensuring a more balanced and resilient agricultural sector.
