“…Demand for water is rising owing to rapid population growth, urbanization and increasing water needs from agriculture, industry, and energy sectors. While realizing water security, NbS can help achieve multiple other SDGs sub-goals, such as "poverty eradication" (SDGs-1, the role of water on livelihoods), "zero hunger" (SDGs-2, and NbS provides sustainable water for agriculture) and other goals (SDGs-3, Good Health and Wellbeing; SDGs-6, Clean Water and Sanitation; SDGs-11, Sustainable Cities and Communities; SDGs-13, Climate Action) (Bremer et al, 2021).
