Rice production in Bangladesh is vulnerable to climate-related risk such as drought, which contributes to food insecurity. Adoption of drought-tolerant rice varieties can play an important role in increasing productivity, food grain supply, and income. However, to the best of our knowledge, no studies have measured the welfare impacts of drought-tolerant rice varieties in the South Asian and Bangladeshi context. Therefore, this study identifies the factors that influence the intensity of adoption and welfare impacts of drought-tolerant rice varieties in Bangladesh. To accomplish these objectives, 300 rice growers from three drought-prone districts of Bangladesh were surveyed. To analyze the impacts, the entire sample was divided into three groups depending on their share of land under drought-tolerant rice variety cultivation: full adopters, partial adopters, and non-adopters. The descriptive statistics, two-limit Tobit model and multivalued treatment effect models were used to analyze the data. According to the findings, training as well as technology-related factors play a major role in boosting the intensity of adoption. Full adopters of drought-tolerant varieties receive 1222-1473 kg higher yield per hectare compared to non-adopters. Based on several treatment effect models, the impact on income ranges from 3.46% to 4.22%. When compared to non-adopters, full adopters can consume 1.02-1.29 months more rice from their own production in a year. Shows about climate change and other relevant topics should be broadcast on the television on a regular basis to raise awareness. Modifying the extension method with modern communication technologies will aid in widespread adoption of new technologies. Drought-tolerant rice varieties can help to mitigate the harmful effects of drought and alleviate poverty in drought-prone areas.
孟加拉国的水稻生产容易受到干旱等与气候相关的风险影响,而干旱会导致粮食不安全。采用耐旱水稻品种对于提高产量、粮食供应和收入可发挥重要作用。然而,据我们所知,尚无研究衡量过在南亚和孟加拉国背景下耐旱水稻品种对福利的影响。因此,本研究确定了影响孟加拉国耐旱水稻品种采用强度和福利影响的因素。为实现这些目标,对来自孟加拉国三个易旱地区的300名水稻种植者进行了调查。为分析影响,根据他们种植耐旱水稻品种的土地份额将整个样本分为三组:完全采用者、部分采用者和非采用者。使用描述性统计、双限托宾模型和多值处理效应模型对数据进行分析。根据研究结果,培训以及与技术相关的因素在提高采用强度方面发挥着主要作用。与非采用者相比,耐旱品种的完全采用者每公顷产量高出1222 - 1473公斤。基于多个处理效应模型,对收入的影响范围为3.46%至4.22%。与非采用者相比,完全采用者每年可从自己的生产中多消费1.02 - 1.29个月的大米。应定期在电视上播放有关气候变化和其他相关主题的节目以提高认识。用现代通信技术改进推广方法将有助于新技术的广泛采用。耐旱水稻品种有助于减轻干旱的有害影响并缓解易旱地区的贫困。
