BLUE-GREEN INFRASTRUCTURE
SLIDE 10
Urban Environment: energy and health security
Heat wave, UHI Air Pollution removal, carbon sequestration Avoidance of emissions (reduced energy use) Wind regime- strong wind, pedestrian level discomfort
Urban Water Ecology: water security
Storm-water drainage- Urban Flood, Drought Water quality - Natural treatment Water balance, Water temperature
Urban Agriculture: food security
Soil protection - Soil stabilization, Increased permeability Nutrient cycle - Waste decomposition and nutrient cycling Production
Urban Bio-diversity: habitat protection
Species diversity, Habitat and corridors.
Blue-Green Network
SLIDE 11
Blue-Green Infrastructure Network
Scale: Macro, Meso, Local and Micro scale Elements: Bits of nature, Patch, Corridor and Matrix Conditions: Healthy, Under Threat, Degenerating and Potential,
SLIDE 12
Meso (matrix, corridor and patches) Macro Scale
SLIDE 13
Micro- (corridors, patches and bits of nature) Local (corridors and patches)
SLIDE 14
Blue-Green Network
Challenges:
Blue-Green Infrastructure Development, Design and Maintenance Culture Finding Opportunities even in small fragmented parcels Performance and benefit assessment quantitatively on long term basis
