Introduction
Grassland ecosystems, which cover half of the world's land surface, are under significant threat from climate change. These ecosystems function as socio-ecological systems, serving essential biological roles and supporting livestock farmers in grazing-based farming. This farming system is crucial for global food security, livelihoods, and environmental sustainability. However, climate change-induced degradation of pastures poses a major challenge, endangering both natural environments and human societies. The negative impacts of climate change on pasture ecosystems affect livestock production and farmers' livelihoods, potentially undermining the perception of sustainable livestock farming as a viable livelihood. This shift has led to pastoral abandonment, resulting in poverty, extensive migration, competition for resources, and conflicts among pastoralist communities. Despite these challenges, there is an opportunity to improve the efficiency, stability, and resilience of this system. Understanding and addressing the current challenges faced by socio-ecological systems in adapting to climate change is crucial. This study examines the challenges livestock farmers face in adapting to climate change within grazing-based farming systems in Tafresh County.
Materials and Methods
This study was conducted in Tafresh County, located in the eastern part of Markazi Province. According to statistics from 2015, the county includes 82 villages with a total population of 24,913, of which 16,493 live in urban areas and 8,420 in rural areas. By examining audit records from 1991 to 2021, a total of 102 customary exploitation systems covering 142,409 hectares of pasture land were audited. Additionally, 2,806 licensed livestock owners and operators managing 38,540 livestock units were identified within these systems. The latest update from the Department of Natural Resources and Watershed Management of Tafresh County reports that there are currently 901 active licensed operators in livestock grazing units. The research began with a review of relevant literature to identify the challenges. Based on this information, a questionnaire was developed with two sections: individual characteristics and a scale for assessing challenges faced by grazing-based livestock units in adapting to climate change. The questionnaire was validated during the field study and approved by natural resources experts in Markazi Province and faculty members from the Department of Agricultural Management and Development at the University of Tehran. To evaluate the internal consistency of the primary questionnaire scale, Cronbach's alpha coefficient was calculated, confirming the reliability of the research instrument. G-Power software was used to determine the sample size, with a 95% confidence level resulting in an estimated sample size of 116 farmers. Data collection involved administering the custom questionnaire through interviews with 116 randomly selected individuals from the 901 livestock farmers. Ultimately, 115 completed questionnaires were analyzed. Statistical analysis of the data was conducted using SMART PLS3 software. Model validation included calculating both Cronbach's alpha index and composite reliability to ensure reliability. Factor loadings exceeding 0.6 were considered favorable in this analysis.
Results and Discussion
The analysis of the challenges faced by livestock farmers in adapting to climate change, using a 48-item scale categorized into social, economic, and environmental damages, highlighted key factors influencing adaptation efforts in Tafresh County. These factors have a significant impact on the climate change phenomenon. Social challenges (β=0.822) were the primary contributors, including limited knowledge of proper livestock management practices, inadequate government support, and poor communication between farmers and agricultural experts. Economic challenges (β=0.667) were also significant, involving issues such as the inability to afford livestock inputs, medicine, and veterinary care, as well as the unprofitability of livestock raising. Environmental challenges (β=0.788) were equally influential, with problems like inadequate water resources, reduced plant cover diversity, and the increased frequency of natural disasters such as floods, hailstorms, droughts, fires, and sudden cold spells. These adverse factors lead to inefficient pasture utilization, reduced fodder availability, and worsening environmental degradation, necessitating adaptation-based management strategies to protect both livestock and pasture ecosystems.
Conclusion
This study highlights the significant impact of climate change on grazing-based livestock farming, particularly regarding water resource access, vegetation diversity changes, and increased exposure to natural hazards. Changes in rainfall patterns and reduced water availability challenge grazing practices and compromise livestock health and productivity. Declines in vegetation diversity and pasture health lower the nutritional value, forcing farmers to find alternative fodder sources. Climate-related events such as water stress, floods, hailstorms, droughts, fires, and sudden cold spells increase the vulnerability of grazing-based livestock systems. Implementing adaptation measures is crucial to mitigate these challenges. To enhance resilience against water stress, protecting water resources in pastures, exploring water storage options, promoting sustainable water management practices, and providing financial incentives such as low-interest credits or subsidies for water-saving technologies are essential. Similarly, initiatives to develop and restore vegetation in pastures, like seed planting, adopting proper grazing practices, cultivating drought-resistant fodder crops, and controlling invasive species, can optimize grazing-based livestock farming. Enhancing access to weather alert systems, conducting training and capacity-building programs to improve preparedness for natural disasters, and promoting smart livestock breeding methods, such as integrated agriculture and agroforestry, are vital. Additionally, implementing watershed and soil protection plans, carbon sequestration projects, and fostering collaboration and knowledge sharing among stakeholders, including formal and informal institutions, will strengthen adaptation efforts. Embracing innovative solutions is imperative to enhance livestock farmers' resilience to climate change.
