Analysis of Private Sector Interest in Blue Green Infrastructure by the Motivation and Abilities (MOTA) framework: A case study in Ho Chi Minh City

Blue-Green Infrastructure is an emerging approach to storm water management in Ho Chi Minh City, helping to mitigate negative effects of excess storm water while providing multiple benefits. While several top-down initiatives for better storm water management practices have been proposed, many initiatives fail to implement or do not perform as expected. There is also a lack of private sector participation in storm water management, where policy and clear regulation are lacking.

This paper identifies the primary factors contributing to private sector participation in Blue-Green Infrastructure projects in Ho Chi Minh City and validates them through a survey of construction specialists, local authority, and residents. A Motivation and Abilities (MOTA) framework analysis reveals primary risk factors being a lack of perceived economic and financial benefits, as well as maintenance concerns. The primary motivational factors are improved public relations, improved selling value, and increased Floor-Area Ratio. Final remarks include incentive recommendations, addressing corruption, and improved education for private developers and local officials.
