Rapid urbanization has led to habitat degradation and loss of biodiversity, posing severe threats to regional sustainability, particularly in extremely vulnerable arid zones. However, systematic research on the assessment indicators, limiting factors, and driving mechanisms of habitat quality in arid regions is notably lacking. This study takes Urumqi, an oasis city in China’s arid region, as a case study and employs the InVEST and PLUS models to conduct a dynamic evaluation of habitat quality in Urumqi from 2000 to 2022 against the backdrop of land use changes. It also simulates habitat quality under different scenarios for the year 2035, exploring the temporal and spatial dynamics of habitat quality and its driving mechanisms. The results indicate a decline in habitat quality. The habitat quality in the southern mountainous areas is significantly superior to that surrounding the northern Gurbantunggut Desert, and it exhibits greater stability. The simulation and prediction results suggest that from 2020 to 2035, habitat degradation will be mitigated under Ecological Protection scenarios, while the decline in habitat quality will be most pronounced under Business-As-Usual scenarios. The spatial distribution of habitat quality changes in Urumqi exhibits significant autocorrelation and clustering, with these patterns intensifying over time. The observed decline in habitat quality in Urumqi is primarily driven by anthropogenic activities, urban expansion, and climate change. These factors have collectively contributed to significant alterations in the landscape, leading to the degradation of ecological conditions. To mitigate further habitat quality loss and support sustainable development, it is essential to implement rigorous ecological protection policies, adopt effective ecological risk management strategies, and promote the expansion of ecological land use. These actions are crucial for stabilizing and improving regional habitat quality in the long term.

T1 - Integrating Multi-Source Data to Explore Spatiotemporal Dynamics and Future Scenarios of Arid Urban Agglomerations: A Geodetector–PLUS Modelling Framework for Sustainable Land Use Planning JF - Remote Sensing N2 - Land use and landscape changes undermine the balance between humans and the environment, threatening sustainable regional development, yet their driving mechanisms and future trends remain insufficiently understood, particularly in arid areas. This study establishes a long-term analytical framework for the temporal evolution and driving mechanisms of land use and landscape patterns in arid areas, based on Landsat remote sensing imagery and socio-economic data. We investigate spatiotemporal evolution trends, driving mechanisms, and spatial non-stationarity of regional landscapes, and apply the Patch-generating Land Use Simulation (PLUS) model to predict future landscape changes under business-as-usual (BAU), economic development (ED), and ecological protection (EP) scenarios. The results show that: (1) Grassland and unused land together account for over 80% of the total area. From 1990 to 2020, built-up land expanded by 1471.58 km 2 , an increase of 190.09%. The comprehensive land use dynamic degree in the Urumqi–Changji–Shihezi (UCS) region was 0.22%, with the highest value observed between 2000 and 2010. (2) At the class level, spatial heterogeneity and fragmentation of different landscape types increased, enhancing regional landscape diversity. (3) Spatiotemporal changes in land use and landscape patterns were driven by the combined effects of natural factors, socio-economic conditions, and policy influences. (4) By 2030, under all three scenarios, unused land is expected to decrease, with the most significant reduction under the EP scenario. Grassland will increase most notably under the EP scenario, built-up land will expand, especially under the ED scenario, and cropland will also grow, mainly under the EP scenario. Forest and water areas will show slight decreases with minimal fluctuations. Overall, the proposed framework effectively captures the spatiotemporal dynamics and driving forces of land use and landscape changes, providing support for the formulation of long-term sustainable development policies.

Workshop Proceedings. N2 - From 3rd to 7th February 2025, 33 participants from 17 European countries gathered on the Isle of Vilm, Germany, to explore the potential of citizen science (CS) in UNESCO Biosphere Reserves (BRs). Hosted by the Biosphere Reserves Institute (BRI) and funded by the German Federal Agency for Nature Conservation (BfN), the workshop aimed to advance the Lima Action Plan and the Eberswalde Declaration by exploring how CS in BRs can increase collaboration with local communities, support environmental education, advance data collection and analysis and strengthen research. The workshop programme included presentations, discussion rounds, group work and opportunities for informal exchange. While some presentations focused on conceptualising CS, most shared and reflected on practical experiences with it in BRs. It was noted that CS encompasses a wide spectrum of activities, ranging from citizens using apps to collect data (e.g., on birds) to research projects initiated and conducted by non-(academic) scientists. Participants shared a strong belief in the power of CS to generate data, engage communities and inspire action. Furthermore, some presentations revealed an intrinsic motivation among local communities to be involved in CS. In terms of education, it was revealed that CS can foster a sense of locality and place attachment, as well as trigger community action through experiential learning. Many speakers emphasised collaboration on both local and global scales as essential for ensuring effective CS, emphasising the value of existing networks, early engagement and transdisciplinary partnerships. Identified challenges included difficulties in recruiting and retaining skilled participants, ensuring data quality and long-term data governance and the lack of (long-term) funding. The case studies revealed that the co-creation of knowledge through CS requires spaces of respectful communication, which often means that scientists need to leave their disciplines to acknowledge different knowledge domains and framings of issues. Participants also called for more meaningful collaboration with schools, policymakers and local groups, while the need for user-friendly tools, training, expert validation and inclusive communication was repeatedly stressed. Furthermore, it was revealed that evaluation criteria specifically designed to assess CS projects and their impacts are still lacking. Additionally, participants called for increased promotion of CS by UNESCO. Solutions proposed included the better identification of local research needs, the continuous reflection of the research process and evaluating to what extent different expectations have been met. Participants emphasised the need for better platforms to exchange knowledge and good practices across BRs, and special attention was given to providing opportunities for youth to be part of CS in BRs, which would contribute not only to the production of knowledge, but also nurture the emotional connection to nature and create opportunities for lifelong learning. Many participants highlighted the need for BR-specific research guidelines, and these were further developed during the workshop, with a focus on the synergies between research and CS. Importantly, as a result of this workshop, the German Commission for UNESCO decided to add CS as a criterion for the designation and evaluation of German BRs. Overall, the workshop showed that CS holds great potential for BRs to bridge science and society and to foster inclusive, participatory sustainable development.
