The conceptualization of the Shared Socioeconomic Pathways (SSPs) framework represented a major leap in scenario development in the context of global environmental change and sustainability, providing significant advances from the previous scenario frameworks-especially the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios. It is highly likely that the SSP concept, along with its scenario narratives and their respective results, including land-use change projections, will play a substantial role in the forthcoming Sixth Assessment Report by the IPCC. Here, we offer some insights that could make the SSPs' projected future changes in global land use more comprehensive and also help improve the interpretability of such projections. For example, instead of focusing on the quantity of each land-use class at various time points which results only in a net change when change is detected between time points, we recommend that the projected gross gains and gross losses in each land-use class across all scenarios should also be considered. Overall, the insights presented could also help pave the way for stronger collaboration between the SSP-climate science community and the land system science community; such collaboration is much needed in addressing the challenges of global environmental change towards a climate-resilient sustainable development pathway.

共享社会经济途径中预计的土地利用变化：见解和影响。

共享社会经济路径 (SSPs) 框架的概念化代表了在全球环境变化和可持续性背景下情景开发的重大飞跃，与之前的情景框架相比取得了重大进展，尤其是政府间气候变化专门委员会 (IPCC) 关于气候变化专门委员会 (IPCC) 的特别报告排放情景。SSP 概念及其情景叙述及其各自的结果，包括土地利用变化预测，极有可能在 IPCC 即将发布的第六次评估报告中发挥重要作用。在这里，我们提供了一些见解，可以使 SSP 对全球土地利用未来变化的预测更加全面，并有助于提高此类预测的可解释性。例如，与其关注不同时间点的每个土地利用类别的数量，这样只会在时间点之间检测到变化时导致净变化，我们建议在所有情景中每个土地利用类别的预计总收益和总损失也应该考虑。总体而言，所提出的见解也有助于为 SSP 气候科学界和土地系统科学界之间加强合作铺平道路；在应对全球环境变化挑战，迈向具有气候适应能力的可持续发展道路时，非常需要这种合作。所提出的见解还有助于为 SSP 气候科学界和土地系统科学界之间加强合作铺平道路；在应对全球环境变化挑战，迈向具有气候适应能力的可持续发展道路时，非常需要这种合作。所提出的见解还有助于为 SSP 气候科学界和土地系统科学界之间加强合作铺平道路；在应对全球环境变化挑战，迈向具有气候适应能力的可持续发展道路时，非常需要这种合作。
