Abstract

Urban land use efficiency (LUE) has garnered global attention due to concerns that urban sprawl could result in significant habitat and biodiversity loss, environmental degradation, etc. Understanding the trends and characteristics of LUE is vital for attaining the United Nation's sustainable development goals (SDGs). This poses a problem, as the suggested LUE indicator not only fail to alleviate but actually amplify the impacts of errors stemming from global data sources. In this study, we conducted an examination of LUE change in over 3200 large cities worldwide from 1985 to 2020, using modified LUE indictors and robust analysis tools. Our findings indicate that the majority (81.2 %) of those cities experienced a significant increase in built-up per capita, posing a great challenge in enhancing land use efficiency. We have observed that disparities among regions are significant and tend to widen from 1985 to 2020. In 2020, North America boast the highest levels of BpC (exceeding 300 m²), while some low-income countries, such as Bangladesh, Somalia, and Yemen, only have a BpC about 20 m². We subsequently propose diverse solutions to replace current uniform requirement, with a specific focus on migrating the deteriorating trend of BpC in low-income region. The study emphasizes the demand for increased efforts and more flexible strategies to enhance global urban LUE by unveiling the challenges and diversity associated with it.

利用稳健指标和分析工具检验1985 - 2020年全球城市土地利用效率的可靠趋势

城市土地利用效率（LUE）引起了全球的关注，因为人们担心城市扩张可能导致严重的栖息地和生物多样性丧失、环境退化等。了解低利用率的趋势和特征对于实现联合国可持续发展目标至关重要。这就产生了一个问题，因为建议的LUE指标不仅不能减轻，而且实际上放大了来自全球数据源的错误的影响。在这项研究中，我们使用改进的城市价值评价指标和稳健的分析工具，对1985年至2020年全球3200多个大城市的城市价值评价变化进行了研究。研究结果表明，大部分城市（81.2%）的人均建筑面积显著增加，对提高土地利用效率提出了巨大挑战。我们观察到，从1985年到2020年，地区之间的差距很大，而且有扩大的趋势。到2020年，北美拥有最高的BpC水平（超过300平方米），而一些低收入国家，如孟加拉国，索马里和也门，只有大约20平方米的BpC。我们随后提出了不同的解决方案，以取代目前的统一要求，并特别关注迁移低收入地区BpC恶化的趋势。该研究强调，需要加大努力，采取更灵活的战略，通过揭示与之相关的挑战和多样性，提高全球城市低效率。

期刊介绍： Habitat International is dedicated to the study of urban and rural human settlements: their planning, design, production and management. Its main focus is on urbanisation in its broadest sense in the developing world. However, increasingly the interrelationships and linkages between cities and towns in the developing and developed worlds are becoming apparent and solutions to the problems that result are urgently required. The economic, social, technological and political systems of the world are intertwined and changes in one region almost always affect other regions.
