<jats:p> Building engineered structures, such as dams and dikes, has been the conventional approach to water management. Some suggest that such “gray” infrastructure make way for “green” ecosystem-based approaches. In this second of three debates, <jats:italic>Science</jats:italic> invited arguments for how these approaches can address the challenge of building the water security of rapidly growing societies worldwide. </jats:p>

<jats:p> Reliance on “hard,” human-engineered structures—“gray” infrastructure—has been the conventional way to manage water needs for economic development. But building dams, piping water, and constructing protective barriers is capital intensive and may address only a few water problems ( <jats:xref ref-type="bibr"> <jats:italic>1</jats:italic> </jats:xref> ). Gray infrastructure often damages or eliminates biophysical processes necessary to sustain people, ecosystems and habitats, and livelihoods. Consequently, there is renewed focus on “green” infrastructure, which can be more flexible and cost effective for providing benefits besides water provision. Supplementing or integrating gray infrastructure with biophysical systems is critical to meeting current and future water needs. Gray and green infrastructures combined are synergistic and can have superior results to one or the other. </jats:p>
