3.2 Green Infrastructure

Green infrastructure refers to a network of natural and semi-natural features that provide ecological benefits within urban areas. This can include parks, green roofs, permeable pavements, rain gardens, and urban forests. The integration of green infrastructure into urban planning helps manage stormwater, improve air quality, enhance biodiversity, and provide recreational spaces for residents. The approach often incorporates principles of landscape ecology to enhance connectivity between natural habitats.

3.3 Participatory Design

Participatory design emphasizes the involvement of community members in the planning and design process. This methodology recognizes that successful ecological urbanism requires input from residents who understand their community's specific challenges and needs. Participatory design techniques include workshops, surveys, and collaborative planning sessions, allowing stakeholders to contribute their knowledge and preferences to the decision-making process.

3.4 Ecological Footprint Analysis

Ecological footprint analysis quantifies the environmental impact of urban areas, measuring their resource consumption in terms of land area. This methodology is crucial for understanding the sustainability of urban environments and identifying areas for improvement. By analyzing the ecological footprint, planners can develop targeted strategies to reduce resource consumption and promote more sustainable land management practices.
