Air quality is a major public health concern, while particulate matter (PM) measurements remain limited by the spatial coverage and high operational costs of reference monitoring stations. This scoping review synthesises the literature on image-based PM estimation from outdoor photos as a potential low-cost approach to increase PM concentration sampling coverage. Methods are classified by input data requirements and modelling...

The sea level rise (SLR) in the Sundarbans areas is higher than the global-average rate of sea rise, and many studies assume that most of the dry land of the Sundarbans will be inundated by the end of the twenty-first century. This study aims to analyze the amount of dry land that can potentially be inundated by SLR in Sundarbans and the impact under different land cover conditions. Four SLR scenarios, a digital elevation data...
