Research on nutrition-sensitive agriculture (NSA) has mostly been aimed at demonstrating its impact on nutrition and explicating underlying pathways, and more rarely at understanding processes and lessons learnt from them. This study aimed to gain insights into the processes that influence behaviour change, contributing to improved caring, feeding and food production practices, using a program theory perspective. It also investigated perceived challenges to the sustainability of interventions and potential solutions, in the context of an NSA program in rural Vietnam. Using a participatory approach, data were gathered on impact pathways and perceived outcomes, on elements of program theory that led to behavioural change, as well as barriers and facilitators. Respondents in semi-structured interviews ( = 30) and seven focus group discussions (total = 76) were selected purposively among program participants. Data was collected and triangulated across several stakeholder groups.
The impact pathways (production-consumption, caring and feeding, and home-grown school feeding) envisaged in the NSA program functioned as intended; synergies were revealed. The increased supply of locally produced nutrient-rich foods not only contributed to the emergence of a promising income sub-pathway but also reinforced synergy with the home-grown school feeding pathway. Improved diets, feeding and caring practices, and school attendance were key outcomes of the program. Successful elements were pathway-specific, such as flexibility in implementing context-appropriate agricultural models. Others, such as benefit-driven motivation and improved knowledge, triggered changes in multiple pathways. Role models, increased self-confidence, and change agents were the main process facilitators. The biggest barrier to both implementation and sustainability was the poor socio-economic conditions of the most disadvantaged households.
This study showed the relevance of NSA programs in addressing undernutrition in remote areas by enhancing self-reliance in local communities. The integration of behaviour change activities proved to be a key strategy in the process to enhance the impact of agriculture on nutrition outcomes. Though outcomes and influencing factors are very context-dependent, lessons on what worked and what did not work could inform the design and implementation of effective behaviour change strategies in future NSA programs in Vietnam and elsewhere.
营养敏感型农业(NSA)的研究主要旨在证明其对营养的影响并阐明潜在途径,而很少关注理解相关过程以及从中吸取的经验教训。本研究旨在从项目理论的角度深入了解影响行为改变的过程,以促进改善照料、喂养和粮食生产实践。该研究还在越南农村的一个营养敏感型农业项目背景下,调查了干预措施可持续性面临的感知挑战及潜在解决方案。采用参与式方法,收集了关于影响途径和感知结果、导致行为改变的项目理论要素以及障碍和促进因素的数据。在项目参与者中,有目的地选取了30名进行半结构化访谈的受访者以及76名参与七次焦点小组讨论的人员。数据收集自多个利益相关者群体并进行了三角互证。
营养敏感型农业项目设想的影响途径(生产 - 消费、照料和喂养以及本土学校供餐)按预期发挥了作用;揭示了协同效应。当地生产的营养丰富食品供应增加,不仅促成了一条有前景的收入子途径的出现,还加强了与本土学校供餐途径的协同作用。改善饮食、喂养和照料实践以及提高入学率是该项目的关键成果。成功要素因途径而异,例如在实施适合当地情况的农业模式方面具有灵活性。其他要素,如利益驱动的动机和知识的提高,则引发了多个途径的变化。榜样、自信心增强以及变革推动者是主要的过程促进因素。实施和可持续性面临的最大障碍是最贫困家庭的社会经济状况不佳。
本研究表明,营养敏感型农业项目通过增强当地社区的自力更生能力,在解决偏远地区营养不良问题方面具有相关性。行为改变活动的整合被证明是增强农业对营养成果影响过程中的关键策略。尽管结果和影响因素非常依赖具体情况,但关于哪些有效、哪些无效的经验教训可为越南及其他地区未来营养敏感型农业项目中有效行为改变策略的设计和实施提供参考。
