11.3 Green infrastructure and urban soil management
2 min read•july 24, 2024
Urban green infrastructure is a game-changer for city environments. It's all about creating networks of natural features that boost environmental, social, and economic benefits. From to , these elements tackle urban challenges head-on.
Managing urban soil is key to successful green infrastructure. It's about improving soil health, enhancing water retention, and supporting biodiversity. Proper soil management techniques, like amending and conditioning, are crucial for overcoming urban challenges and maximizing the benefits of green spaces.

Green infrastructure forms a network of natural and semi-natural features in urban areas designed to provide environmental, social, and economic benefits
Plays crucial role in urban soil management by improving soil health and structure, enhancing water infiltration and retention, reducing soil erosion and compaction, and supporting biodiversity in
Includes rain gardens, bioswales, permeable pavements, green roofs, and urban forests which mitigate urban environmental challenges
Benefits of urban green spaces
Environmental benefits include improved air quality, reduced urban heat island effect, increased carbon sequestration, and enhanced
Social benefits encompass improved mental and physical health, increased recreational opportunities, and enhanced community cohesion
Economic benefits result in increased property values, reduced energy costs for buildings, and decreased stormwater management expenses
Ecosystem services provide habitat for urban wildlife (birds, insects) and support pollination for urban agriculture (community gardens, rooftop farms)
Urban Soil Management for Green Infrastructure
Soil management for green infrastructure
Crucial soil characteristics include texture and structure, organic matter content, water-holding capacity, and nutrient availability
Soil quality impacts plant growth and survival through root development and establishment, drought resistance, and disease resistance
Urban soil management techniques involve and conditioning, and , and aeration and decompaction
Challenges in urban environments include contamination mitigation (heavy metals, pollutants), compaction prevention, and pH regulation
Water management techniques include irrigation system design, rainwater harvesting (rain barrels, cisterns), and drought-tolerant plant selection (native species, succulents)
Plant selection prioritizes native species, manages root zones, and establishes pruning and maintenance schedules
Monitoring and adaptive management involve regular soil testing, plant health assessment, and adjusting practices based on observations
