Learning from the Pause

The current pandemic has certainly imposed a pause on the world. Hopefully, we will rebuild more sustainably through understanding the co-benefits (Newell et al., 2018) of conserving biodiversity, climate adaptation, mitigation and improving human well-being through green infrastructure.

Investing in resilient nature-based solutions equally as we invest in conventional grey infrastructure will be a critical component of any new green recovery. Nature-based solutions encompass both natural and naturalized landscapes as well as purpose-built green infrastructure (green roofs, wildlife crossings, parks systems and so forth). One example is bioswales which offer multiple co-benefits; they are designed to slow, hold and filter stormwater using natural plantings which also provide biodiverse pollinator and bird habitats, and which simultaneously provide human well-being benefits of shade, urban cooling and active transportation pathways (for bikes and pedestrians). Similarly, public parks can be designed with co-benefits for flood protection, using barrier-based or permeable green infrastructure (flood berms or infiltration zones) which provide a thriving habitat for local biodiversity, essential landscape and open space for social gathering and mental well-being -- needs that have been well-documented during the pandemic lock-down (Samuelsson et al., 2020).

If reframed as essential services and as critical as grey infrastructure, it is an important strategy for the new green recovery that many are recommending.
