“...diarrhea kills more children every year than HIV/AIDS, malaria and tuberculosis put together...� - COLORS magazine. fall 2011
Contaminated Watershed
The Barkese Reservoir is the main source of potable drinking water for the residents of Kumasi, the second largest city in Ghana with a population of 1,171,311. This reservoir provides 80% of the total pipe borne water to the Kumasi metropolis.
60% of Kumasi’s local food supply is grown in downstream farming communities.
Rapid population growth, institutional failures and industrial activities are all causes of pollution of the Aboabo River. The main anthropogenic causes were identified as indiscriminate dumping of refuse, channeling of raw sewage, open defecation, discharge of untreated effluents and dumping of industrial waste into the Aboabo River.
Failed Development
“Business as Usual� sewer infrastructure currently incomplete
“Leapfrogging” Investment
Existing Erosion Stream
JHS school
Flood risk endangers civic and institutional spaces
Optimum Stream
Phase 1 - Stewardship Site preparation and solid waste collection
Establish stewardship zone
Relocation strategies for flood impacted households
Flood risk impacts livability and health
Phasing 2 - Protection and Recovery Start recovery of nutrient cycles (composting begins)
Protect school through defensible landscapes
Relocation and densification strategies
Introduce ecological systems as defense mechanism
Phasing 2 - Protection and Recovery
Tree Nurseries Establish Stewardship at SchoolTraining Program: Building with Solid Waste Harvestable Trees and crops
Erosion Rehabilitation: Improved access Containment of floodable zone: Land building Water Channeling
Phasing 3 - Demonstration
Implement education and labor programs
Deploy alternative wastewater treatment and reuse strategies
Construct pediatric clinic, public toilets, and training hall
Illustrate value of on-site waste streams
Phasing 3 - Demonstration
Public Toilet: Collect Human Waste Rainwater Collection
New Roads: Improved access
Establish Stewardship at SchoolTraining Program: Building with Solid Waste Harvestable Trees and crops
Road Infrastructure
Expand access throughout site to important regional centers
Phasing 4 - Infrastructure
Develop housing typologies that support economies of waste
Develop network of transportation nodes to increase access to site
Pave critical transportation routes
Strengthen opportunity through improved infrastructure
