It seems like a 'no brainer' to use urban greening to help cities adapt to increasing heat, but the uptake of green infrastructure, such as trees and vegetated roofs, surfaces and walls, is slow. Why?
The report criticises the state’s failure to adequately integrate the planning of land use development and transport priorities, but falls into the same trap itself.
Infrastructure Australia's latest report is substantial but, critically, it fails to incorporate the transport thinking needed to develop more compact cities that work better for everyone.
The urban landscape is complex and ever-changing in cities such as Perth, but digital aerial photography can now monitor even the smallest changes.
Constant, complex changes in cities and mine sites are hard to monitor. Drawing on digital aerial photography, it's now possible to track land-use and vegetation changes in areas as small as 10-20cm.
Traffic jams in major African cities such as Lagos, pictured here, as well as Uganda’s Kampala, are a major drain on productivity.
Kampala generates about 60% of Uganda's GDP. In the coming decade urbanisation is the single largest opportunity to spur economic growth in the coming decade.
Traffic in Accra, Ghana. With more people moving into cities, careful town planning is critical for sustainable development.
Urban planning and development in Africa has been fraught with many challenges. A study of Accra and Nairobi provides some lessons on what needs to improve.
