摘要

人为的气候变化正在增加干旱的频率和严重程度,从而加速土地退化,危害生态系统,威胁水安全和生计。然而,长期干旱对土地覆盖变化的全球影响的研究仍然很少。本研究分析降水数据以确定干旱条件,并将其与土地覆盖数据集进行比较。该分析探讨了1992年至2021年期间的三个分析维度:国家层面、收入水平和气候水平。结果表明,干旱与土地覆盖变化之间存在密切联系,低收入国家的变化最为显著。在干旱易发地区,树木、农田和稀疏植被受到的影响最大,相关性强于未受影响地区。该研究为全球干旱事件与土地覆盖变化之间的复杂关系提供了有价值的见解,这些关系因区域和经济背景而异,并强调了可持续土地管理和适应措施等主动战略的缓解作用。

Exploring land cover change after prolonged droughts at the global level.

Anthropogenic climate change is increasing the frequency and severity of droughts, which accelerate land degradation, harm ecosystems, and threaten water security and livelihoods. However, the global impact of prolonged droughts on land cover changes remains poorly studied. This research analyses precipitation data to identify drought conditions and compares them with land cover datasets. The analysis explored three analytical dimensions, over the period 1992-2021: country level, income level, and climatic level. Results show a strong connection between droughts and land cover changes, with low-income countries experiencing the most significant changes. In drought-prone areas, trees, cropland, and sparse vegetation are the most impacted, with correlations stronger than in unaffected regions. This study provides valuable insights into the complex relationship between global drought events and land cover changes, varying across regions and economic contexts, and highlights the mitigating role of proactive strategies such as sustainable land management and adaptation measures.

期刊介绍: We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
