KAUST Urban Lab: Building sustainable cities

KAUST · Dec 2

KAUST's Urban Lab is developing green infrastructure solutions to combat the urban heat island (UHI) effect in arid climates. Researchers are focusing on using vegetation for shading and evapotranspiration, as well as increasing albedo with reflective surfaces. The team is using machine learning to analyze heat patterns and urban expansion to inform sustainable architecture and landscape design. Why it matters: This research is crucial for creating more livable and sustainable urban environments in Saudi Arabia and other regions facing desertification and water scarcity.

A Novel CNN-LSTM-based Approach to Predict Urban Expansion

arXiv · Mar 2

This paper introduces a novel two-step method for predicting urban expansion using time-series satellite imagery. The approach combines semantic image segmentation with a CNN-LSTM model to learn temporal features. Experiments on satellite images from Riyadh, Jeddah, and Dammam in Saudi Arabia demonstrate improved performance compared to existing methods based on Mean Square Error, Root Mean Square Error, Peak Signal to Noise Ratio, Structural Similarity Index, and overall classification accuracy.
