Nature-based solutions: The one for all answer to climate hazards

[...]

Deep-rooted species, such as certain native grasses and shrubs, enhance groundwater retention, alleviating drought impacts. A United Nations Development Programme (UNDP) report notes that NbS remain underutilised in water management, often overshadowed by grey infrastructure.

Yet, interventions like bio-dykes, vegetated embankments combining native plants with engineered structures, have proven effective in preventing flood intrusion, protecting agricultural lands, and stabilizing riverbanks in regions like South Asia and Europe.

Selecting climate-resilient vegetation is critical. Heat-resistant and water-retaining species, such as drought-tolerant grasses or mangroves in coastal areas, can address extreme heat and water scarcity simultaneously.

Hybrid approaches that combine NbS with engineered solutions, like green roofs paired with stormwater systems, create resilient urban ecosystems. Beyond environmental benefits, NbS can enhance livelihoods.
