Grassland degradation poses a serious threat to biodiversity, ecosystem services, and human well-being. In this study, we investigated grassland degradation in Zhaosu County, China, between 2001 and 2020, and analyzed the impacts of climate change and human activities using the Miami model. The actual net primary productivity (ANPP) obtained with...

The NH 58 area in India has been experiencing an increase in landslide occurrences, posing significant threats to local communities, infrastructure, and the environment. The growing need to identify areas prone to landslides for effective disaster risk management, land use planning, and infrastructure development has led to the increased adoption...

National monitoring of forests is essential for tracking progress towards various global environmental goals, including those of the Kunming-Montreal Global Biodiversity Framework and the Paris Agreement. Inconsistent national definitions of “forest”, however, can complicate the tracking of global progress towards achieving these goals. The FAO’s...

Coastal social-ecological systems (SES) are essential for the wellbeing of coastal communities and the wider society. However, in many parts of the world coastal SES face rapid change, and ultimately degradation. In this paper we unravel the mechanisms and implications of change in coastal SESmobilising multiple sources of knowledge, including...

Study region: Bosten Lake (Xinjiang, China). Study focus: This paper mainly focuses on quantifying changes in water storage of Bosten Lake using multi-mission satellite data. From Landsat images, we firstly extracted the lake area changes between 2003 and 2022 with the help of the modified normalized difference water index (MNDWI); Secondly, we...

Since the 26th Conference of Parties (COP26) of the United Nations Framework Convention on Climate Change (UNFCCC) in 2021, global society, including Asian countries, has entered the phase of how to implement a long-term transition roadmap to net-zero greenhouse gas emissions (GHGs).

Assessing heat-related health risks is important for sustainable urban development. Although fine-scale information (e.g., at the community/neighborhood or city block level) is ideal for identifying and mitigating these risks, previous studies have preferred to work at the administrative unit level. High-resolution Local Climate Zone (LCZ) maps, i...
