Bridging Science and Sustainability: Zahraa Alobaidy Presents Nature-Based Solutions for Water Management
Baghdad, July 23, 2025 – As climate-related challenges continue to pressure water
infrastructure across the globe, environmental engineer Zahraa Alobaidy,
M.Sc., delivered a powerful international workshop titled “Nature-Based
Solutions (NbS) for Sustainable Water Management.” The workshop, hosted
virtually by the Institute of Technology – Baghdad, was organized in
cooperation with the University of Cologne, Germany, as part of ongoing
efforts to share interdisciplinary knowledge between the Middle East and
Europe.
Reimagining Water Management with Nature
Alobaidy’s
presentation began with a fundamental question: How can we manage urban water
in a way that works with nature rather than against it?
She
provided a clear comparison between Low Impact Development (LID) and Nature-Based
Solutions (NbS). While LID focuses primarily on stormwater management
through design practices such as infiltration trenches and permeable surfaces,
NbS extends this concept further. NbS refers to actions that protect, restore,
or mimic ecosystems to provide sustainable benefits across multiple dimensions:
water security, climate resilience, biodiversity, and social wellbeing.
Technical Deep Dive: Engineering with Nature
The
core of the presentation focused on practical engineering applications
for nature-based water management. Alobaidy introduced attendees to several
design models for LID components, drawing from real-world standards and manuals
including:
- The Canadian SWMP Manual
- The US EPA’s Stormwater LID Framework
- The LID Treatment Train Tool (LID TTT) developed by Canadian conservation authorities
Attendees gained insights into how infiltration trenches are sized and placed, the hydraulic properties of filter layers, and how percolation rates are calculated for stormwater drawdown. Beyond the numbers, the presentation emphasized minimizing surface disturbance and protecting natural flow paths in site development to enhance infiltration and water purification.
Real-World Examples from Europe
One
of the workshop’s strengths was its integration of international case studies.
Drawing from her academic and field experience in Germany, Alobaidy shared
photo documentation and design observations from a variety of green
infrastructure sites:
- Green Roofs at Ruhr Bochum University that reduce urban heat while storing
rainwater
- Constructed Wetlands in Essen that biologically filter water while creating public
green space
- Riparian Forest Buffers along rivers in Pennsylvania that enhance biodiversity and reduce
erosion
- Vegetated Swales and Rain Gardens that intercept runoff and support
pollinator habitats
These
examples underscored the multi-functional nature of NbS—providing not
only stormwater control but also improving air quality, increasing property
values, and contributing to community aesthetics.
Governance, Policy, and Implementation
The
second half of the workshop focused on the role of governments,
municipalities, and research institutions in promoting NbS. Alobaidy
discussed the policy layers needed to support LID adoption—from local zoning
regulations to national water strategies.
She
highlighted success stories from cities like Portland, Milwaukee, and Fort
Collins, where nature-based solutions have been effectively integrated into
land-use plans. She also pointed to organizations like ICLEI – Local
Governments for Sustainability, which help cities develop frameworks to
embed nature into urban infrastructure.
Key
governance challenges such as funding gaps, land-use competition,
and policy inertia were openly addressed, along with recommendations for
community engagement and stakeholder collaboration.
A Roadmap for Regional Progress
Closing
the session, Alobaidy emphasized the importance of pilot projects at
neighborhood and institutional levels. She encouraged:
- Stronger cross-disciplinary collaboration between engineers, ecologists, and city planners
- Inclusion of NbS in university curriculum and professional training
- Monitoring and evaluation systems to ensure project longevity and adaptation
The
workshop concluded with a call for turning research into action—and using
natural infrastructure to combat water scarcity, flood risks, and urban heat
across both developed and developing regions.
