Floating agriculture in Bangladesh. Bangladesh experiences severe flooding every year, mostly in the south. Residents are pretty much stranded. For weeks, sometimes months, kids are blocked from going to school and parents lose income and access to food. The above shows one method for dealing with food shortages. A floating mat is created, soil piled on top, and crops planted in the soil. After harvest, the mat and soil are used as fertilizer for regular land cultivation.
It’s a clever solution, but keep in mind doesn’t scale up to meet the needs of 100’s of thousands of people affected by the floods.
