Flooding is among the most frequent and economically damaging natural hazards worldwide, and its occurrence has intensified in many regions due to climate change, rapid urbanization, and increasing population pressures. Pakistan is particularly vulnerable to flood disasters, experiencing substantial economic losses, infrastructure damage, and human casualties each year. Conventional flood management strategies in the country have largely relied on grey infrastructure, including embankments, levees, and drainage systems. However, these approaches are increasingly challenged by changing climatic conditions and growing environmental pressures. Nature-based solutions (NBS) have emerged as a sustainable alternative or complementary approach by utilizing ecosystem processes to mitigate flood impacts while providing environmental and socio-economic co-benefits. This study evaluates flood risk characteristics in Lasbela District, Balochistan, and examines the applicability of NBS for flood mitigation. A mixed-methods approach was adopted, integrating hydrological analysis, GIS-based spatial assessment, historical flood data review, and comparative evaluation of conventional and nature-based interventions. Rainfall analysis of the August 2021 flood event revealed precipitation ranging from 162 to 186 mm across major locations within the study area. The findings indicate that NBS can contribute significantly to reducing flood peaks, enhancing infiltration, improving ecosystem resilience, and supporting biodiversity conservation. The study highlights the potential of integrating NBS into adaptive flood risk management frameworks to strengthen long-term resilience and promote sustainable development in flood-prone regions.
