The world is rapidly becoming more urban, but as cities grow in size, their impact on Earth’s biodiversity grows in step. As a new mapping effort led by landscape architects at the University of Pennsylvania shows, the conflict is far more dire than most of us appreciate.

Of the 423 cities growing in one of the world’s 36 recognized biodiversity “hotspots”, at least 90 percent are sprawling straight into habitat harboring endangered species. That’s the stark conclusion of Hotspot Cities, a sweeping new report on conflicts between urban growth and biodiversity. Penn urbanism professor Richard Weller, who led the analysis, told Earther he wanted to shed light on an issue that receives scant attention in the planning and design communities…


Green infrastructure for disaster resilience : exploring connections with scenario planning

Despite growing disaster losses in the US, hazard mitigation and other forms of emergency management planning remain fragmented from other ‘mainstream’ local planning efforts. Surprisingly, there are few examples in local planning where connections have been made between disaster resilience and green infrastructure objectives, despite that green infrastructure planning is becoming more widespread as communities better understand the ecological and human benefits provided by open space, parkland and other protected natural areas. This is a missed opportunity for promoting urban resilience, since many green infrastructure functions are complementary to resiliency goals, and investments in green infrastructure generally resonate with a broader community constituency than single-function hazard mitigation projects. In this context, the objective of the dissertation is to test how innovative scenario planning techniques can be used to draw stronger connections between green infrastructure and disaster resilience objectives in local community planning…
