Image segmentation and geographic object-based image analysis (GEOBIA) were proposed around the turn of the century as a means to analyze high-spatial-resolution remote sensing images. Since then, object-based approaches have been used to analyze a wide range of images for numerous applications. In this Editorial, we present some highlights of...

A few studies have evaluated the impact of land use land cover (LULC) change on surface water quality in the Vietnamese Mekong Delta (VMD), one of the most productive agricultural deltas in the world. This study aims to evaluate water quality parameters inside full- and semi-dike systems and outside of the dike system during the wet and dry season...
Working Paper
While the initial pieces of evidence indicate that COVID-19 induced economic slowdown and lockdown present short-term benefits to air quality and the environment, these also pose a double-edged challenge in the long-term. On one side, the slowing down of the economy can have an adverse impact on countries’ ongoing efforts towards climate mitigation...
