Abstract: Researchers and water managers have turned to green stormwater infrastructure, such as bioswales,
retention basins, wetlands, rain gardens, and urban green spaces to reduce flooding, augment surface
water supplies, recharge groundwater, and improve water quality. It is increasingly clear that green
stormwater infrastructure not only controls stormwater volume and timing, but also promotes
ecosystem services, which are the benefits that ecosystems provide to humans. Yet there has been little
synthesis focused on understanding how green stormwater management affects ecosystem services.
The objectives of this paper are to review and synthesize published literature on ecosystem services
and green stormwater infrastructure and identify gaps in research and understanding, establishing a
foundation for research at the intersection of ecosystems services and green stormwater management.
We reviewed 170 publications on stormwater management and ecosystem services, and summarized
the state-of-the-science categorized by the four types of ecosystem services.Major findings show that:
(1) most research was conducted at the parcel-scale and should expand to larger scales to more closely
understand green stormwater infrastructure impacts, (2) nearly a third of papers developed
frameworks for implementing green stormwater infrastructure and highlighted barriers, (3) papers
discussed ecosystem services, but less than 40% quantified ecosystem services, (4) no geographic
trends emerged, indicating interest in applying green stormwater infrastructure across different
contexts, (5) studies increasingly integrate engineering, physical science, and social science approaches
for holistic understanding, and (6) standardizing green stormwater infrastructure terminology would
provide a more cohesive field of study than the diverse and often redundant terminology currently in
use. We recommend that future research provide metrics and quantify ecosystem services, integrate
disciplines to measure ecosystem services from green stormwater infrastructure, and better
incorporate stormwater management into environmental policy. Our conclusions outline promising
future research directions at the intersection of stormwater management and ecosystem
services.

Abstract: Due to rapid urbanization, population growth and economic drivers, megacities and metropolises around
the world face increasing water challenges, such as water scarcity, degradation of water resources and
water-related risks such as flooding. Climate change is expected to put additional stress on already
strained metropolitan water management systems. Although there is considerable research on river basin
management and on urban water management, there is hardly any on metropolitan water management.
Similarly, as urban water generally emerges from and returns to river basins, it is surprising how little
literature there is that explicitly connects these two spheres of governance. Hence this review paper
addresses the: What does a review of the literature tell us about the overlap and reconciliation between
the concepts of Integrated Water Resources/River Basin Management and Metropolitan/Urban Water
Management, particularly in relation to megacities? Based on an extensive literature review, this paper
concludes that the key differences between the two are in relation to their overarching framework, scope,
inputs and outputs of water and in relation to dealing with extreme weather events. The literature review
reveals how sustainable and integrated urban water management increasingly adopt principles and
rhetoric from integrated water resource management, this has yet to translate into significant changing
practices on the ground. Urban water management still often occurs independently of river basin issues.
Achieving coherence between river basin management and sustainable/integrated urban water management
is even more difficult in metropolises and megacities, because the latter consists of multiple
political-administrative units. The article concludes that the scalar mismatch between river basin management
and metropolitan/megacity water governance deserves much greater attention than it currently
receives in the academic and policy debates
