Abstract

Improved rice varieties (IRVs) play a significant role in establishing food security and improving livelihood in the Global South since its introduction in the 1960s. However, the adoption of new IRVs has remained relatively low. This low adoption poses a challenge to rice-producing and consuming countries as they are increasingly threatened by production shortages, malnutrition, and poor rice quality. Many empirical studies have attempted to identify the determinants influencing the adoption of IRVs by distinguishing the characteristics between adopters and non-adopters. This review showed a consensus on the important determinants influencing the adoption of IRVs in the Global South. Findings synthesized from 99 studies suggested that variables (farm size, education, information access and farm location) examined extensively are not necessarily the most important determinants of adoption when undertaking a weighted analysis. Terrain, source of seed and technology-related attributes (perceived yield, maturity, ease of use, marketability and technical efficiency) are more important determinants of adoption, with determinants changing according to adoption type (probability or intensity of adoption), variety type and region. The recommendations for future adoption studies include: incorporating more technology-specific variables, increasing research for overlooked regions and variety types, shifting away from predominant static analysis by capturing the dynamics of the adoption process, and considering the potential biases in analyses. This review will facilitate the development of targeted interventions and policies that promote IRV adoption in the Global South.

发展中国家改良水稻品种的采用:综述
改良水稻品种自20世纪60年代引进以来,在全球南方国家建立粮食安全和改善生计方面发挥了重要作用。然而,新irv的采用率仍然相对较低。这种低采用率对稻米生产国和消费国构成了挑战,因为它们日益受到产量短缺、营养不良和稻米质量差的威胁。许多实证研究试图通过区分采用者和非采用者之间的特征来确定影响采用内部自愿者的决定因素。这一审查表明,对影响全球南方国家采用内部病毒的重要决定因素达成了共识。综合99项研究的结果表明,在进行加权分析时,广泛检查的变量(农场规模、教育、信息获取和农场位置)不一定是采用的最重要决定因素。地形、种子来源和技术相关属性(感知产量、成熟度、易用性、适售性和技术效率)是采用的更重要决定因素,决定因素根据采用类型(采用的概率或强度)、品种类型和地区而变化。对未来采用研究的建议包括:纳入更多特定于技术的变量,增加对被忽视的区域和类型的研究,通过捕捉采用过程的动态来改变主要的静态分析,并考虑分析中的潜在偏差。这项审查将有助于制定有针对性的干预措施和政策,以促进发展中国家采用内部病毒。
