DEFINITION OF GREEN INFRASTRUCTURE
- Green infrastructure or blue-green infrastructure refers to a network that provides the “ingredients” for solving urban and climatic challenges by building with nature. The main components of this approach include stormwater management, climate adaptation, the reduction of heat stress, increasing biodiversity, food production, better air quality, sustainable energy production, clean water, and healthy soils, as well as more human centered functions, such as increased quality of life through recreation and the provision of 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. More recently scholars and activists have also called for green infrastructure that promotes social inclusion and equity rather than reinforcing pre-existing structures of unequal access to nature-based services. “Blue infrastructure” refers to urban infrastructure relating to water. Blue in frastructure is commonly associated with green infrastructure in urban environments and may be referred to as “blue-green infrastructure” when being viewed in combination. Rivers, streams, ponds, and lakes may exist as natural features within cities, or be added to an urban environment as an aspect of its design. Coastal urban developments may also utilize pre-existing features of the coastline specifically employed in their design. Harbours, quays, piers, and other extensions of the urban environment are also often added to capture benefits associated with the marine environment. Blue infrastructure can support unique aquatic biodiversity in urban areas, including aquatic insects, amphibians, and water birds. There may considerable co-benefits to the health and wellbeing of populations with access to blue spaces in the urban context. Green infrastructure could be safely expanded as to cover all economic and social infrastructure such as roads,railways, ports, airports, and buildings. Studies on this part of green infrastructure need to be conducted in Indonesia on how these facilities could be co-exist with sustainable envirinment in land, sea, and underground. Thus, investment on infrastructure could as well be sustaining the environment. This is the principle of concession-conservation that need too be embraced.

spaces in the urban context. - In an environmental way, green infrastructure can be viewed as natural life support system – an interconnected network of waterways, wetlands, woodlands, wildlife habitats and other natural areas; greenways, parks and other conservation lands; working farms, ranches and forests; and wilderness and other open spaces that support native species, maintain natural ecological processes, sustain air and water resources and contribute to the health and quality of life for communities and people.
