Closing Governance & Financing Gaps to Scale Blue-Green Infrastructure in Muscat

Muscat’s transition toward Blue-Green Infrastructure faces structural financial and governance barriers that limit its ability to scale beyond isolated projects. While early initiatives have demonstrated clear hydrological and resilience benefits, the wider system still relies on funding models, institutional arrangements, and planning practices that were designed for fully grey stormwater networks.

What Is Holding Back Muscat’s Ability to Scale Blue-Green Infrastructure?

Greening Muscat’s stormwater systems requires more than engineering innovation. The report identifies structural financial, institutional, and regulatory barriers that must be resolved before Blue-Green Infrastructure can move from isolated pilot projects to a connected, city-wide resilience network.

• The financial sustainability challenge
  Stormwater management is currently dependent on central government allocations, which are not tied to long-term BGI upkeep. The report recommends new financing tools such as stormwater utility fees based on impervious surface area and retention credits.
• Institutional and capacity roadblocks
  Most local engineering remains rooted in grey infrastructure. Scaling BGI requires specialised training in hydrology and landscape design. The report highlights the need for government-supported training programmes.
• Integrated planning and zoning limitations
  Effective deployment depends on aligning the Ministry of Housing, Muscat Municipality, and the Ministry of Water Resources. Updated zoning must require new developments to manage runoff on-site.

Why Closing These Gaps Matters

Muscat’s flood risk cannot be addressed through grey infrastructure alone. Establishing dedicated financing, improving institutional capacity, and enforcing integrated zoning are essential for building a coherent network of hybrid stormwater assets.

Building a Governance Framework for Resilient Urban Growth

A clear policy framework enables Muscat to shift from reactive flood response to proactive resilience planning. By closing these governance and financing gaps, Muscat can unlock the investment required to transform scattered initiatives into a unified system.
