Assessing runoff under changing land use/land cover (LULC) and climatic conditions is crucial for achieving effective sustainable water resource management on a global scale. In this study, the focus was predictions across three diverse Indian watersheds—Wunna, Bharathapuzha, Mahanadi—spanning distinct agro-climatic zones to capture varying hydrological complexities. The soil assessment (SWAT) tool used simulate future influenced by LULC climate change explore related sustainability implications, including challenges proposing countermeasures through action plan (SAP). methodology integrated high-resolution satellite imagery, cellular automata (CA)–Markov model projecting changes, downscaled data representative concentration pathways (RCPs) 4.5 8.5, representing moderate extreme scenarios, respectively. SWAT calibration validation demonstrated reliable predictive accuracy, with coefficient of determination values (R2) > 0.50 confirming reliability in simulating processes. results indicated significant increases surface due urbanization, reaching >1000 mm, 600 400 mm southern southeastern Wunna, northwestern Mahanadi, respectively, especially 2040 RCP 8.5. These findings indicate that quality, agricultural productivity, urban infrastructure may be threatened. proposed SAP includes nature-based solutions, like wetland restoration, climate-resilient strategies mitigate adverse effects partially achieve development goals (SDGs) clean action. This research provides robust framework watershed similar regions worldwide.

Thermal comfort in urban commercial spaces significantly impacts both business performance and public well-being. Traditional evaluation methods relying on field surveys expert assessments are often time-consuming labor-intensive. This study proposes a novel vision–language model (VLM)-based agent system for thermal assessment spaces, simulating eight distinct heat-sensitive roles with varied demographic backgrounds through prompt engineering using ChatGPT-4o. Taking Harbin Central Street, China as case study, we first validated accuracy ASHRAE scale evaluations of 30% samples (167 images) by 50 experts, then conducted simulations followed spatial interpretability analyses. Key findings include (1) significant correlation between VLM (r = 0.815, p < 0.001), confirming method feasibility; (2) notable heterogeneity across agents, demonstrating the VLMs’ capacity to capture perceptual differences among social groups; (3) analysis revealing higher eastern regions compared western central areas despite inter-role variations, consistency agents; (4) shade vegetation being identified primary influencing factors that contribute agent’s decision making. research validates VLM-based agents’ effectiveness evaluation, showcasing their dual capability replicating traditional while capturing group differences. The proposed approach establishes paradigm efficient, comprehensive, multi-perspective environments.
