Short description of the intervention
As a solution to the increasing population, pollution and high energy consumption, the municipal government of Shiraz has launched the Green City project in 2008. The main aim of this initiative is to reforest the city's periphery and encourage citizens to plant gardens on rooftops and the private sectors to adhere to the city’s development plan with all construction projects.

Goals of the intervention
The main aim of this initiative is the reforestation of the city’s periphery, other specific goals include:
1. To improve the air and water quality in Shiraz.
2. To reduce energy consumption by planting and maintaining trees.
3. To reduce the intensity and volume of water runoff (by building roof gardens), urban flooding (by extending the green belt and controlling floods in the heights) and prevent soil erosion (by cultivating appropriate plant species).
4. To reduce energy costs and create municipal income by harvesting olives to produce olive oil from the olive trees planted.
5. To improve the living conditions of marginalised people.
6. To create recreational spaces within the city [1].
Quantitative targets
1. To plant trees in an area of 14,195 hectares.
2. Olive tree plantation for 13,500 hectares.
3. Create six roof parks ( 23,560 sq. m) of which 2 are car parking roofs of 5,000 sq. m.
4. Create 10 hectares linear park. [1]

Implementation activities
The Green City project consists of four actions:
1. The Urban Forest Development Project planted trees in an area of 14,195 hectares in the heights and mountains surrounding the city. The Barme Shour Olive Plantation Project has been nominated by the International Olive Council as the biggest olive garden in the world. There were altogether eight planting projects within the Urban Forest Development Project. The majority of the planted trees are olive trees (13,500 hectares), but needle leaf trees and almond trees have also been planted.
2. Roof Parks: The goal was to create recreational spaces within the city, mainly on the roofs of multi-storey car parks. Six roof parks were built, of which two with an area of 5,000 sq. m built by the municipality. The other four roof parks were built in cooperation with private sector entities. The total area of roof parks is estimated to be 23,560 sq. m.
3. Linear Parks: These parks will make the city ascetically more attractive and create a suitable path for pedestrians to spend their free time. The first park was built along the Chamran Boulevard in 2008, covering an area of 10 hectares. Eight other linear parks have been built with a total area of 43 hectares (including the Chamran Boulevard).
4. Roof Gardens: The municipality encouraged both construction companies and citizens to establish roof gardens in their projects. The steering committee for the project comprised members of the “Parks and Green Spaces Organization” of the municipality of Shiraz who worked in collaboration with the local university. [1]

Please specify Replicability/Transferability
The liaison between different authorities (state and local authorities) was recognized and led to a nationwide law proposing similar projects (covering a total area of 40 thousand hectares) to be carried out in the Fars Province. There was also an agreement signed by other cities to follow this example. [1]
Impacts, benefits
Description of environmental benefits
1. The per capita green space increased from 13 sq. m. to 85 sq. m.
2. Air pollution and heat island effects reduced.
3. The intensity and volume of water runoff (by building roof gardens) and urban floods (by the expansion of the green belt and controlling the floods in the heights) are also addressed.
4. The project increases groundwater resources.
5. The plantation produces 325,000 cubic metres of oxygen each day, which will improve air quality in the city. [1, 2]
Economic impacts
Description of economic benefits
1. The project promotes nature tourism.
2. The building of green spaces and roof gardens minimizes the costs that are usually caused by water runoff or urban floods.
3. The city is less dependent on imported olive oils now. Oil from the olive trees has increased the municipal income. [1]
Description of social and cultural benefits
1. More people can enjoy their free time in a way that minimizes mental health problems caused by urbanization.
2. The opportunity to exercise at the newly built sports facilities will improve citizens' health and positively impact young people, who may be less likely to turn to drugs or commit crimes. [1]
