Wetland Conversion for Farmland Offers Minimal Crop Gains, Heightens Flood Risk

New research from the Chinese Academy of Sciences, published in *Nature Sustainability*, shows that converting wetlands to farmland contributes only 0.1% to global crop output. This practice significantly increases flood exposure, with 52% of reclaimed croplands in major flood-prone areas, experiencing 23 times higher average flood exposure than existing croplands. The findings highlight environmental and agricultural inefficiencies.
