ABSTRACT: Replacing rice cultivation is a measure that mitigates water scarcity and climate change. This study used the extended theory of planned behavior (TPB) to predict rice growers’ intentions to alter their current rice cropping system to other, less water-consumptive products. Using survey data collected from 220 randomly sampled rice growers in southwestern Iran, structural equation modeling showed that environmental concerns positively affected the subjective norm (β = 0.57), perceived behavioral control (β = 0.16), moral norm (β = 0.37), self-identity (β = 0.26), and habit (β = 0.39). Environmental concerns indirectly affect farmers’ intentions through self-identity and habit. Attitude and self-identity positively affected and habit negatively affected behavioral intentions. The results showed that the extended TPB has superior predictive ability over TPB in predicting grower intentions. Extended TPB predicted 35% of the farmers’ intentions, while TPB predicted 30%. Given the strong indirect impact of environmental concerns on the farmers’ intention to change cultivation patterns, political efforts through the media and training campaigns should be aimed at raising environmental concerns, risk perception and awareness, and clarifying the risks of water scarcity. Extension agents may increase farmers’ willingness to change cultivated crops by disseminating information to farmers about measures needed to prepare the land, costs of cultivating alternative crops, and benefits of changing cultivation patterns to improve farmers’ attitudes.

用耗水量较低的作物代替水稻:对伊朗的绿色政策影响

摘要: 替代水稻种植是缓解水资源短缺和气候变化的措施。本研究使用扩展的计划行为理论 (TPB) 来预测水稻种植者将其当前的水稻种植系统改为其他耗水量较少的产品的意图。使用从伊朗西南部 220 名随机抽样的水稻种植者收集的调查数据,结构方程模型表明,环境问题对主观规范(β = 0.57)、感知行为控制(β = 0.16)、道德规范(β = 0.37)、自我-身份(β = 0.26)和习惯(β = 0.39)。环境问题通过自我认同和习惯间接影响农民的意图。态度和自我认同对行为意图有积极影响,习惯对行为意图有负面影响。结果表明,扩展 TPB 在预测种植者意图方面比 TPB 具有更好的预测能力。扩展的 TPB 预测了 35% 的农民意图,而 TPB 预测了 30%。鉴于环境问题对农民改变耕作模式的意愿具有强烈的间接影响,通过媒体和培训活动的政治努力应该旨在提高环境问题、风险认知和意识,并澄清水资源短缺的风险。推广代理可以通过向农民传播有关整地所需措施、种植替代作物的成本以及改变耕作模式以改善农民态度的好处的信息,从而提高农民改变种植作物的意愿。扩展的 TPB 预测了 35% 的农民意图,而 TPB 预测了 30%。鉴于环境问题对农民改变耕作模式的意愿具有强烈的间接影响,通过媒体和培训活动的政治努力应该旨在提高环境问题、风险认知和意识,并澄清水资源短缺的风险。推广代理可以通过向农民传播有关整地所需措施、种植替代作物的成本以及改变耕作模式以改善农民态度的好处的信息,从而提高农民改变种植作物的意愿。扩展的 TPB 预测了 35% 的农民意图,而 TPB 预测了 30%。鉴于环境问题对农民改变耕作模式的意愿具有强烈的间接影响,通过媒体和培训活动的政治努力应该旨在提高环境问题、风险认知和意识,并澄清水资源短缺的风险。推广代理可以通过向农民传播有关整地所需措施、种植替代作物的成本以及改变耕作模式以改善农民态度的好处的信息,从而提高农民改变种植作物的意愿。通过媒体和培训活动开展的政治努力应旨在提高对环境的关注、对风险的认识和认识,并澄清水资源短缺的风险。推广代理可以通过向农民传播有关整地所需措施、种植替代作物的成本以及改变耕作模式以改善农民态度的好处的信息,从而提高农民改变种植作物的意愿。通过媒体和培训活动开展的政治努力应旨在提高对环境的关注、对风险的认识和认识,并澄清水资源短缺的风险。推广代理可以通过向农民传播有关整地所需措施、种植替代作物的成本以及改变耕作模式以改善农民态度的好处的信息,从而提高农民改变种植作物的意愿。
