- W2902326216 abstract "Paddy rice and pond aquaculture are important for Vietnam’s food security and contribute significantly to the GDPthrough exports. Knowledge about the production of rice and aquatic goods is significant in the contexts of foodsecurity, water management, trade policy, greenhouse gas emissions and hydrological modelling. Aquacultureponds and paddy fields in Asia are often located in vulnerable regions, such as costal lowlands and river deltas,which are susceptible to sea level rise, floods and droughts, salt water intrusion and other hazards while at the sametime battling issues of urban encroachment, stagnating yields and increased demand due to population growth.The Sentinel-1 satellites are the first constellation that offers a free and open data archive of high spatialand temporal resolution SAR data with a global coverage. This vast amount of data is particularly suited for timeseries analysis and holds great potential for future land use/land cover (LU/LC) change assessments. We presenttwo studies showing the potential of Sentinel-1 for pond aquaculture and rice mapping. The study area for allstudies was the complete Mekong Delta, Vietnam.Pond aquaculture was mapped by using Sentinel-1 time series, water thresholding, open-source segmentationalgorithms and the derivation of shape parameters to differentiate aquaculture ponds from other water bodies.For the paddy rice mapping study we used a superpixel segmentation algorithm to create Sentinel-1 time seriesat the object level, instead of the pixel level, and derived rice area as well as seasonality by means of a straightforward decision tree algorithm. To manage the large data volume we devised workflows that incorporatedcloud computing via Google Earth Engine for data processing. All products have been calculated at 10m spatialresolution." @default.
