J. Agr. Sci. Tech. (2021) Vol. 23(3): 487-498 Application of Weather Forecasts in Farm Management Decisions: The Case of Iran L. Parsi1 and H. Maleksaeidi1* ABSTRACT Weather forecasts have potential for improving adaptation and resilience of agricultural systems to climate changes; however, there is still uncertainty on the factors affecting the use of this information in farm management decisions. This survey study was conducted on the application of weather information by 213 farmers selected through a stratified random sampling technique in 21 rural areas of Veys, in Khuzestan Province. The results indicated that perception of the reliability of weather information providers, availability of weather forecast information, self-efficacy, and subjective norm were the key drivers for using weather forecast information in the farm management decisions. Based on the results, confidence to the information providers was low among farmers. In addition, social norm about using weather information in practice was not strong in the study area. The results of the study highlighted the need for improving beliefs and values of farmers and their communities about the importance of using weather forecast information for adaptation to climate change. Keywords: Adaptation to climate change, Agricultural decision making, Weather threats. INTRODUCTION live in the arid and semi-arid regions of developing countries and are vulnerable to Agricultural production is significantly climate change due to lack of facilities affected by extreme temperature events (Biglari et al., 2019; Erena et al., 2019; (Jamshidi et al., 2018; Bijani et al., 2017; Trinh et al., 2018; Kumar et al., 2016; Hatfield and Prueger, 2015; Zhang et al., Maleksaeidi and Karami, 2013; Altieri and 2017; Chen et al., 2016), the variation in the Nicholls, 2017). In such a situation, it is rainfall patterns (Khatri-Chhetri et al., 2017; important to empower farmers in order to Crane et al., 2011), wind speed trends make the right management decisions on the (Sharratt et al., 2015), and climate disasters farm for withstanding climate changes, Downloaded from jast.modares.ac.ir at 11:05 IRST on Tuesday September 28th 2021 such as floods and droughts (Yu et al., 2014; adapting to these changes, and improving Maleksaeidi et al., 2016).

For 23% of the country's population and supplies example, in 1992, when the Brazilian 80% of the country's food (Mohammadian government warned farmers about the Mosammam et al., 2016), various studies occurrence of the El Niño and provided have indicated significant impacts of climate them free drought tolerant seeds, the country change on agricultural productivity in Iran. witnessed an increase in the agricultural For instance, Nassiri et al.

Generally, a precise prediction of rainfed wheat - as one of the most important climate change gives farmers an opportunity cereals in Iran (Mohammadian Mosammam to approach weather threats, allows them et al., 2016)- would be reduced by 18%.

Overall, without paying Over the past two decades, advances in attention to the adaptation strategies, climate technology have made it possible to improve change would limit agricultural production the quality and lead-time of weather in different areas of Iran (Karimi et al., forecasts and their interpretations (Kusunose 2018). In such circumstances, providing and Mahmood, 2016; Kenkel and Norris, weather forecasts and using them in practice 1995). Theoretically, with increasing is crucial for farmers to prepare for climate uncertainty in weather and climate patterns, changes and adaptation to these changes it is expected that the value of weather (Losee and Joslyn, 2018). information for farmers will increase and, Farmer's decision to rely on weather under an ideal management scenario, we see forecast information is likely a function of more application of such information in many factors (Kusunose and Mahmood, decision making (Kusunose and Mahmood, 2016). These include availability of weather 2016). However, lack of sufficient studies forecasts (Changnon, 2004; Frisvold and on the adoption of weather information in Murugesan, 2013; Artikov et al.. 2006), practice by users, particularly by poor confidence in accuracy of these forecasts resource and vulnerable farmers who live in (Kusunose and Mahmood, 2016; Kox et al., Downloaded from jast.modares.ac.ir at 11:05 IRST on Tuesday September 28th 2021 developing countries such as Iran, has led to 2015; Hu et al.
