Building with Nature in Marine Infrastructure: Toward an Innovative Project Arrangement in the Melbourne Channel Deepening Project

Globally, there is an increasing pressure on coastal and marine ecosystems. The development of marine infrastructure is causing additional ecological impacts on these systems. To reduce ecological impacts innovative approaches of marine infrastructure development are being developed. These approaches, such as Building with Nature, aim to integrate ecological and social dynamics in the creation of coastal and marine infrastructure. This integration has implications for the development and management of these projects. To understand opportunities for Building with Nature approaches, this article analyzes the development of the Melbourne Channel Deepening project in Australia that developed from a conventional, state-led project toward a Building with Nature arrangement. This article shows that a Building with Nature project arrangement differs not just substantially in its ecological focus and primacy from a conventional project arrangement, but also in its leading discourse, its actor coalition, its power and resources applied, and the rules of the game through which the project is designed and implemented. We conclude that developing a Building with Nature project requires a specific arrangement that allows for an early involvement of both ecological and social dynamics.
