Imrahor River Valley Pondscape, located southeast of Ankara, covers 12 ponds, initially created for flood prevention and water retention. Managed by Ankara Metropolitan Municipality, it offers public access and recreational activities such as walking and picnicking. Over time, rapid urbanization, real estate development, and road constructions have altered the area’s hydrology, reducing natural water flow and threatening biodiversity. The valley’s ponds, once vital for biodiversity, now face pollution from nearby industrial activities, threatening their ecological value. Despite these challenges, the area remains an important urban green space.

The success of the Imrahor River Valley pondscape restoration can serve as a model for other urban and semi-urban areas facing similar challenges. The implementation of Nature-based Solutions, such as pond restoration and biodiversity management, can be replicated in other regions to address both environmental and societal needs. The integration of green infrastructure in urban planning, especially in rapidly urbanizing regions, could mitigate the negative impacts of development and provide long-term ecological and societal benefits.
The Imrahor River Valley faces ongoing threats from urbanization, which reduces flood mitigation capacity and degrades water quality, impacting biodiversity. The absence of a robust policy framework and lack of coordinated management among stakeholders exacerbate these issues. Strengthened environmental protections, effective waste management, and limiting further real estate development are crucial. Collaboration between local authorities, environmental organizations, and landowners is essential for the pondscape’s restoration. Securing funding for long-term conservation and integrating nature-based solutions will ensure the pondscape’s sustainability.
