The study was conducted to evaluate the economic and environmental impacts of water-saving technologies (WST) on Boro rice (Oryza sativa; var. BRRIdhan 29) farming in Bangladesh. A total of 480 farmers (80 focal and 400 control) were selected as sample from Mymensingh, Comilla, Bogra and Gaibandha districts. Focal farmers were selected purposively and a limited amount of financial support was provided to them to implement WST. On the other hand, control farmers were selected randomly. They did not receive any financial support and continued practicing conventional irrigation methods. For analyzing the data, a combination of descriptive, mathematical and statistical techniques was used. The study revealed that 62.5 and 37.5% of focal farmers adopted alternate wetting and drying (AWD) and system of rice intensification (SRI) methods, respectively, where the majority of them were within the late majority group in terms of adoption. The profitability and productivity of Boro rice, as well as water productivity, were comparatively higher for focal farmers compared to control farmers. Furthermore, focal farmers’ irrigation amount for producing Boro rice was significantly lower than control farmers. The study also revealed that focal farmers’ income from rice production was 24.6% higher than control farmers. Input support, motivation, training programs and extension services are recommended to implement to raise the awareness and enrich the knowledge of the farmers on water-saving technologies.

评估节水技术对孟加拉国博罗水稻种植的影响：经济和环境视角

该研究旨在评估节水技术 (WST) 对孟加拉波罗水稻 (Oryza sativa; var. BRRIdhan 29) 种植的经济和环境影响。从 Mymensingh、Comilla、Bogra 和 Gaibandha 地区共选择了 480 名农民（80 名重点农民和 400 名对照农民）作为样本。有目的地选择重点农民，并为他们提供有限的财政支持来实施 WST。另一方面，对照农民是随机选择的。他们没有得到任何财政支持，继续使用传统的灌溉方法。为了分析数据，使用了描述性、数学和统计技术的组合。研究显示，62.5% 和 37.5% 的重点农民分别采用了交替干湿 (AWD) 和水稻强化系统 (SRI) 方法，其中大多数人在采用方面属于晚期多数群体。与对照农民相比，重点农民的波罗水稻的盈利能力和生产力以及水生产力相对较高。此外，重点农民生产博罗水稻的灌溉量显着低于对照农民。研究还显示，重点农民从水稻生产中获得的收入比对照农民高 24.6%。建议实施投入支持、激励、培训计划和推广服务，以提高农民对节水技术的认识并丰富他们的知识。与对照农民相比，焦点农民的比例相对较高。此外，重点农民生产博罗水稻的灌溉量显着低于对照农民。研究还显示，重点农民从水稻生产中获得的收入比对照农民高 24.6%。建议实施投入支持、激励、培训计划和推广服务，以提高农民对节水技术的认识并丰富他们的知识。与对照农民相比，焦点农民的比例相对较高。此外，重点农民生产博罗水稻的灌溉量显着低于对照农民。研究还显示，重点农民从水稻生产中获得的收入比对照农民高 24.6%。建议实施投入支持、激励、培训计划和推广服务，以提高农民对节水技术的认识并丰富他们的知识。
