自2000年代初引入这一术语以来，土地共享与土地节约的二分法引发了大量关于粮食生产与生态功能之间关系的讨论。支撑这些方法的理论跨越了学科和意识形态的界限，并经常在一般的经济与生态背景下概述。这两种战略都提出了关于农业生产与生态功能之间关系的相互竞争的模型。目前的工作介绍了一个概念综合统一的替代模型下一个单一的连贯的框架。本文提出了一个将农业生产与生态功能联系起来的广义模型，以协调这些相互矛盾的观点。此外，一个概念的范式转变，建议处理这个问题，从产量目标到保存阈值。本文提供的理论手段，以确定环境和政策条件下，土地共享战略，基于低投入和单位耕地的影响小，可以竞争的生物多样性保护和食品安全的综合目标的土地节约的方法。
Since the introduction of the terms in the early 2000s, the land sharing versus land sparing dichotomy has sparked considerable discussion stemming from the relationship between food production and ecological function. The theory underpinning these approaches straddles disciplinary and ideological boundaries and is frequently outlined within a general economy versus ecology background. Both strategies have come up with competing models on the relationship linking agricultural production and ecological function. The present work introduces a conceptual synthesis to unify alternative models under a single coherent framework. A generalized model linking agricultural production with ecological function that can harmonize these conflicting views is presented. In addition, a conceptual shift of paradigm is suggested to approach the issue, moving from yield targets to preservation thresholds. This article provides the theoretical means to identify the environmental and policy conditions under which land sharing strategies, based on low inputs and low impact per unit of cultivated land, can compete with land sparing approaches for the combined goals of biodiversity preservation and food safety.
