Editorial: re-city

Climate change has led to urgent calls for environmental action and justice, which is likely to include increased urban vegetation. The benefits of this planting could go beyond ecological and climate benefits to contribute to decolonisation and environmental and spatial justice and build on the well-documented links between ecological and human wellbeing. In Aotearoa New Zealand, past and ongoing injustices resulting from colonisation have disconnected Māori (the Indigenous people) from their land. Māori see themselves reflected in the landscape and te taiao (the natural world). The process of colonisation has mostly erased natural heritage, intrinsic to Māori identity, from urban areas. Many plants in urban areas represent colonial identity rather than this natural heritage, and many of the native plants that have been planted originate from other parts of the country. Through reviewing the literature, this article argues for research that determines the benefits of urban planting design prioritising plants that naturally occurred in the past, termed here ‘plants of place’, in public places. In settler colonial countries, where it is an accepted practice to acknowledge built and predominantly colonial heritage, making pre-colonial natural heritage visible can have many co-benefits. It has the potential to contribute to climate change mitigation and adaptation, decolonisation efforts, spatial justice and environmental justice. Celebrating natural heritage and planting ‘plants of place’ can contribute in some part to righting past injustices and preparing for a changing future.

Cities are increasingly employing green infrastructure, defined as a network of multi-functional open spaces within cities and between cities – including green corridors, green streets, formal parks and street trees – to promote resilience and provide clean air, flood protection and erosion control. Yet there is a growing link between these efforts and rising property values and – in some cities, including Washington, DC – displacement. This history of greening and subsequent displacement can hinder successful green-infrastructure implementation. The geographical areas with the greatest need for these amenities and other resilience strategies are often those with high concentrations of low-income, racial minorities who have traditionally been disenfranchised from local planning and development processes due to a lack of knowledge and limited access, as well as institutional racism. In these areas, the perception of green infrastructure is that of something planned by others, for others, with little direct benefit to the community. This exploratory research, which examines lived experiences, builds upon the quantitative documentation of gentrification and demographic shifts in Washington, DC. Through a series of listening sessions, the study explores residents’ experiences of green infrastructure, gentrification and civic engagement in their community. The study uncovers ways in which policymakers and planners can increase support for and the success of green-infrastructure implementation by amplifying the voices of stakeholders, including communities with vulnerable populations, in the planning process.
