In the last 25 years, unplanned and dispersed urban development has become the norm rather than the exception mostly in medium and small cities of the global south, a region with high poverty rates and weak institutions in charge of land use changes. This paper is based on environmental discourses and governance policy integration to address the limitations in preventing the conversion of open land, which provides ecosystem services, into settlement land. It analyzes the case of the Metropolitan Zone of Queretaro in central Mexico, which has experienced particularly high rates of urban expansion in recent years. This paper focuses on the private sector's significant contribution to urban sprawl, a situation linked to the following deficits: policy domain integration deficit, which is related to competing goals among multi-level, multi-scale and multi-sector actors; the interdisciplinary deficit, which requires various procedures and instruments to promote stakeholder collaboration; and the democracy deficit, which involves micro-level actions rather than substantive policy design to encourage citizens to become agents of change and develop awareness of the value of nature in cities.

可持续城市土地规划的治理和政策局限性。墨西哥一案。

在过去的25年中，无计划和分散的城市发展已成为一种规范，而不是例外情况，在全球南部的中小城市中，这是一个例外，该地区贫困率高且负责土地使用变化的机构薄弱。本文基于环境论述和治理政策整合，以解决防止将提供生态系统服务的开放土地转变为定居土地的局限性。它分析了墨西哥中部克雷塔罗大都会区的情况，该地区近年来经历了特别高的城市扩张速度。本文着眼于私营部门对城市扩张的重大贡献，这种状况与以下赤字有关：政策领域整合赤字，与多层次竞争目标相关，多尺度和多部门的行为者；跨学科的赤字，这需要各种程序和手段来促进利益相关者的合作；民主赤字涉及微观行动而不是实质性的政策设计，以鼓励公民成为变革的推动者，并提高人们对城市自然价值的认识。
