Abstract The conceptualization of farmland fragmentation varies across different scientific disciplines and units of analysis. Although a large body of literature on this phenomenon exist, yet there is no comprehensive understanding about the underlying reasons behind this conceptual variety and how it affects the management of different fragmentation scenarios. Consequently, policy makers and research scholars are unable to devise suitable fragmentation management strategies, which leads to contradictory, irrelevant and inappropriate interventions. This study explicitly and comprehensively displays how and why the farmland fragmentation conceptualizations differ, and which derived scenarios exist. The goal is to develop the typology of fragmentation which can guide farmland fragmentation management decisions for food security. This guide connects to the framework of the Sustainable Development Goals, notably SDGs 1,2,12,13 &15. The study draws on rationalist theory and adopts an integrative concept-centric qualitative approach which builds on the analysis of the existing body of multi-disciplinary literature on farmland fragmentation and on deductive logical reasoning to create new comprehensive scientific knowledge, as an informative guidance for future research and policies. The analysis revealed an ontological and epistemic variety of both the spatial units (such as plot, parcel, farm, and farmland or land block) and the social and physical characteristics which underlie the description of land fragmentation. Moreover, the study identified a diversity of land fragmentation forms falling into two categories of Physical and Tenure fragmentation, whose extent and measurements are determined by specific local conditions and vary from case to case. These can separately apply in practice in different land areas or coexist in the same area under a typology of 40 different fragmentation scenarios based on various mathematical combinations of its spatial and non-spatial desciptors at different levels (parcel,farm,land block). As land managers need to be aware of all farmland fragmentation scenarios, we posit that any farmland fragmentation management intervention is a combination of various spatial and non-spatial effectors in order to be responsible and sustainable. Therefore, since the management of farmland fragmentation varies from scenario to scenario, any attempt to control it should consider the understanding of all the possible scenarios in a given area (as have been identified in this study) as a precondition for action. This is relevant because it would allow to grasp the causes, impacts (positive and negative), the conditions determining the problematic and rational scenarios of farmland fragmentation, and their functional distinctiveness at different spatial levels.

农田碎片化广场：情景分析与研究差距

摘要 农田碎片化的概念因不同的科学学科和分析单位而异。尽管存在大量关于这种现象的文献，但对于这种概念多样性背后的根本原因以及它如何影响不同碎片场景的管理，还没有全面的了解。因此，政策制定者和研究学者无法设计合适的碎片化管理策略，从而导致相互矛盾、不相关和不适当的干预措施。本研究明确而全面地展示了农田破碎化概念的不同之处和原因，以及存在哪些衍生情景。目标是开发可以指导农田碎片化管理决策以实现粮食安全的碎片化类型。本指南与可持续发展目标的框架相关，特别是可持续发展目标 1、2、12、13 和 15。该研究借鉴理性主义理论，采用以概念为中心的综合定性方法，该方法建立在对现有农田碎片化多学科文献的分析和演绎逻辑推理的基础上，以创造新的综合科学知识，作为对未来的信息指导。研究和政策。分析揭示了空间单位（例如地块、地块、农场和农田或土地块）以及构成土地破碎化描述的社会和物理特征的本体论和认知多样性。此外，该研究确定了土地破碎形式的多样性，分为物理和土地使用权破碎两类，其范围和测量值由特定的当地条件决定，并因情况而异。这些可以在实践中分别应用于不同的土地区域或在基于不同级别（地块、农场、土地块）的空间和非空间描述符的各种数学组合的 40 种不同破碎场景的类型学下共存于同一区域。由于土地管理者需要了解所有农田碎片化情景，我们假设任何农田碎片化管理干预都是各种空间和非空间效应因素的组合，以便负责任和可持续。因此，由于农田碎片化的管理因情景而异，任何控制它的尝试都应将了解给定区域内所有可能的情景（如本研究中已确定）作为采取行动的先决条件。这是相关的，因为它可以了解农田破碎的原因、影响（正面和负面）、决定农田破碎的问题和合理情景的条件，以及它们在不同空间层次上的功能独特性。
