Assessing effectiveness of nature-based solution with big earth data: 60 years mangrove plantation program in Bangladesh coast

Abstract Background In the climate change context, nature-based solution (NBS) is considered one of effective tools to increase resilience socio-ecological system. The concept coincides with government’s attempts afforestation and reforestation programs that have been going on for 60 years in Bangladesh. This study, therefore, envisaged understanding how NBS (mangrove reforestation) works promote through synthetization remote sensing-based big earth data, statistical tools, models. study took entire coast Bangladesh except Sundarbans Reserve Forest rolled back 1962 work years’ time series data. Declassified CORONA satellite imagery along Landsat was used, which first-ever attempt ecosystem Results study's main innovation spatially establish effectiveness NBS. critically assessed estimated stable lands their socio-economic benefits as part As NBS-derived context change, it sequestrated carbon mangrove forests. A significant positive relationship observed between mangroves lands. Near about 448,011 ha agricultural land stabilized due intervention whose economic value 18,837 million USD. addition, 29,755.71 kt program. Conclusions still development stage very little or no has done so far measuring labeling Therefore, our can innovatively contribute scientific community show three domains (social, ecological) changing climatic scenario.
