Learning from Floods—How a Community Develops Future Resilience

Abstract

Settlements close to rivers, the sea, and hills are among those most vulnerable to floods. The hilly terrain region experiences higher rainfall than the lowlands due to the orographic effect. As a result, excessive rains feeding major rivers cause a rapid rise in water level resulting in frequent breaks of the riverbanks. The flood hence covers the inhabited lowlands with water and silt, causing loss of lives and properties. The affected communities need practical coping alternatives to deal with the intensity and the increasing exposure to floods. The Sustainable Development Goals (SDG6) identify the sustainable management of water and sanitation as one of their key objectives. This study identifies resilience in practice focusing on how communities create resilience and develop sustainable river catchment management. A qualitative method was used, involving observations, interviews, and community surveys with one of the most flood-prone populations, the New Zealand Northland community. A desktop study containing government publications and flood records compliments the thematic analysis result and strengthens the discussions. Social connections, participation in self-protection training, and maintaining the catchment were among the main findings of the study. This study recommends for community-led response plans integrated with infrastructure improvements and collaboration with councils to reduce the risk of future floods.
