flood-risk
Flood risk refers to the likelihood and potential impact of land inundation events on ecosystems and agricultural systems. For plant science, flooding poses direct physiological challenges including oxygen deprivation in root zones, which can disrupt nutrient uptake, trigger anaerobic stress responses, and cause widespread crop losses. Understanding how plants detect, tolerate, or adapt to waterlogged conditions is critical for developing flood-resilient varieties and informing land management strategies in an era of increasing flood frequency.

This study examined why urban flooding keeps worsening in Iwo, Nigeria, finding that residents' awareness of flood risks and community behaviors are as important as physical infrastructure in determining flood vulnerability.
Flood risk awareness was most strongly linked to prior training on flood risk reduction (factor loading 0.919) and knowledge of household preventive measures (0.924).
Three resilience pathways were identified: engineering/structural interventions explained 31.3% of variance, institutional measures 26.2%, and ecological/environmental strategies 16.8% — together accounting for 74.3% of total variance.
Community perceptions clustered around five drivers of flooding, with poor drainage infrastructure scoring highest (0.876), followed by inadequate emergency response (0.851).
