Green Infrastructure

Week 9 Lecture by Carlos Bartesaghi

Green Infrastructure or blue-green infrastructure is a network providing the “ingredients” for solving urban and climatic challenges by building with nature. The goal of Green Infrastrucure (GI) is to deliver EcoSystem Services (ESS) to protect biodiversity.

The main components of this approach include stormwater management, climate adaptation, less heat stress, more biodiversity, food production, better air quality, sustainable energy production, clean water and healthy soils, as well as the more anthropocentric functions such as increased quality of life through recreation and providing shade and shelter in and around towns and cities. Green infrastructure also serves to provide an ecological framework for social, economic and environmental health of the surroundings.

Ecosystem Services (ESS) involves 4 categories:

  • supporting
  • provisioning
  • regulating
  • cutural

This grouped ecosystem services into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and crop pollination; and cultural, such as spiritual and recreational benefits. The benefits of cultural changes include health, security and social relations.

The benefits of GI also include economic (proprty and land valuation, tourism), social (community development, educational resources) and environmental (flood elevation, land remediation)
