Landsat observations have charted the erosion of the banks of the ever-changing Padma River, a major distributary of the Ganges in Bangladesh. This is vividly shown in this animation produced by NASA Earth Observatory, which “shows 14 false-color images of the Padma river between 1988 and 2018 taken by the Landsat 5 and 8 satellites. All of the images include a combination of shortwave infrared, near infrared, and visible light to highlight differences between land and water.” More on the erosion of the Padma River here.

Six months into the crisis, the priority in Bangladesh is to prevent an emergency within an emergency. The single greatest challenge to refugee protection is the physical environment of the settlements themselves, notably the congestion, access challenges due to a lack of roads and pathways, the high rates of water contamination and the significant risk of epidemics. These risks disproportionately affect the most vulnerable, notably children, pregnant women, single-headed households and people with disabilities. This already dire situation could further deteriorate during the upcoming monsoon season, as large parts of the refugee sites could be devastated by flash floods or landslides and become inaccessible.

Be advised: it’s a big, graphics-heavy page.
