We can expect to see continued innovation in the field of green infrastructure as architects and engineers work together to create more efficient and sustainable construction practices. Additionally, advancements in technology will allow for better monitoring and maintenance of green infrastructure systems.

Overall, as society becomes increasingly conscious of the impact of development on the environment, we can expect to see a continued push for more widespread implementation of green infrastructure in architecture and engineering. It will become an essential aspect of design as we move towards a more sustainable future.
