Monsoon-related floods have devastated millions of people in South and East Asia since early June 2020.
One of the countries most severely affected has been Bangladesh, where at least a quarter of the country was inundated, NASA Earth Observatory said in a recent article.
NASA Earth Observatory used a combination of infrared and visible light to make it easier to see the boundary between water and land. Earth Observatory also published the photo of flooding on Jul 25 in natural colour.
In the false-coloured images, water appears navy blue and black; clouds are white or cyan; and vegetation is bright green.
As of Jul 31, the Bangladesh Flood Forecasting and Warning Centre reported water levels along the Jamuna River were at or above “danger level.”Almost a million homes were inundated, and more than 1,500 square kilometres of farmland were damaged across the country. Several areas are also isolated due flooded roads.
Government officials tried to prepare for the monsoon season, but recent disasters made planning difficult.
The country is recovering from Cyclone Amphan, which hit its coasts in May 2020. And the COVID-19 pandemic has constrained response efforts.
