摘要

农业是南部非洲农村家庭的主要生计，作物生产是粮食和收入的重要来源。虽然政府和发展伙伴提供种子和作物投入，以提高作物生产和粮食安全，但种子安全和粮食安全之间的因果关系并不总是显而易见的。目的研究津巴布韦东部奇马尼马尼地区小农种子安全与粮食安全的关系。具体而言，它旨在研究不同的种子系统如何促成不同的种子安全结果，探索家庭特征对种子和粮食安全的影响，并确定影响这些结果的更广泛的社会经济、环境和政策相关因素。最终，该研究旨在制定一个框架，加强对种子安全和粮食安全之间关系的理解，从而为支持小农的抵御力和生计提供见解。方法采用入户调查（227人）、深度访谈、焦点小组等方式收集数据。利用系统视角和象限类型学，该研究分析了不同农业生态、种子系统和社会环境因素的种子和粮食安全，形成了一个框架，说明了它们之间的相互关系。结果表明，种子与粮食安全之间存在复杂的非线性关系，受社会经济、政治和气候因素的影响。我们的发现对种子安全总是确保粮食安全或种子不安全总是导致粮食不安全的假设提出了质疑。该研究强调了利用种子分发和补贴来解决种子安全问题的挑战，并敦促采取针对具体情况的干预措施，解决系统性制约因素并反映农民的现实。

Towards a holistic framework: Exploring the relationship between seed security and food security dynamics among smallholder farmers in Chimanimani, Zimbabwe

Context

Agriculture is the primary livelihood for households in rural Southern Africa, with crop production a crucial source of food and income. Although government and development partners provide seed and crop inputs to enhance crop production and food security, the causal link between seed security and food security is not always evident.

Objectives

This study aims to investigate the relationship between seed security and food security among smallholder farming households in Chimanimani, eastern Zimbabwe. Specifically, it seeks to examine how different seed systems contribute to varying seed security outcomes, explore the influence of household characteristics on both seed and food security, and identify the broader socio-economic, environmental, and policy-related factors shaping these outcomes. Ultimately, the study intends to develop a framework that strengthens understanding of the relationship between seed security and food security, thereby providing insights to support the resilience and livelihoods of smallholder farmers.

Methods

Data were collected via a household survey of 227 participants, in-depth interviews with key respondents, and focus groups. Using a systems lens and quadrant typology, the study analysed seed and food security across diverse agro-ecologies, seed systems, and socio-environmental factors, leading to a framework illustrating their interrelationships.

Results and conclusions

Results reveal a complex, non-linear relationship between seed and food security, shaped by socio-economic, political, and climatic factors. Our findings question assumptions that seed security always ensures food security or that seed insecurity always causes food insecurity.

Significance

The study highlights challenges of using seed distribution and subsidies to address seed security, and urges context-specific interventions that address systemic constraints and reflect farmers' realities.

期刊介绍： Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments. The scope includes the development and application of systems analysis methodologies in the following areas: Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making; The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment; Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems; Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
