Urban streams are increasingly vulnerable to ecological degradation due to the pressures of urbanization, including altered hydrology, pollution, and biodiversity loss. In the article “From Space to Stream: Combining Remote Sensing and In Situ Techniques for Comprehensive Stream Health Assessment,” published in Remote Sensing (2025), researchers present an innovative approach to monitoring the health of urban streams. By integrating satellite imagery from the Copernicus program, drone-based surveys, chemical analyses, and geophysical measurements, the study offers a multi-dimensional assessment of the Almyros and Gazanos streams in Heraklion, Crete. The findings reveal distinct anthropogenic pressures on each stream—eutrophication in Almyros linked to agricultural runoff, and urban pollution in Gazanos—highlighting the necessity for comprehensive monitoring strategies to inform effective stream management and policy implementation.
