Ecological conservation has become a core issue of global concern, and ecosystem services (ES) are fundamental to achieving sustainable development. However, integrated assessments of ES dynamics, spatial heterogeneity, and future land use scenarios in Mongolia remain insufficient. This study utilized Land Use and Land Cover (LULC) data from 2000...

Urban heat in rapidly growing megacities is spatially uneven, yet the relative influence of built form, socioeconomic activity and blue-green spatial configuration remains insufficiently resolved in cities of the Global South. This study examines neighbourhood-scale controls on land surface temperature (LST) in Delhi, India, using a single clear...
