Area characterisation

Paris is vulnerable to flooding from the Seine river. It is also a compact mineral city, increasingly subject to the heat island effect. Unpaving, greening and planting trees are thus real challenges and absolute necessities. Fortunately, implanting refreshing pockets of nature on permeabilized soil is made possible by the globally dense and homogeneous repartition of schoolyards. This is just what this project aims at, together with more education- and climate security-oriented purposes.The “Oasis” Schoolyards programme takes place in the wider framework of Paris’ Resilience Strategy. As such, it also attempts to meet the local requirements of socio-spatial inclusion, public environmental health and climate change mitigation.

Objective

  • Reduce the local heat island effect
  • Provide pupils with a healthy and stimulating learning environment
  • Educate residents to risk culture on climate change
  • Make refuges of freshness available to the most vulnerable populations
  • Create numerous meeting spaces to spur conviviality and solidarity

Actions

  • By using a light-coloured, low carbon footprint substrate with a modular porosity on schoolyards grounds, the latter are expected to be much cooler.
  • The ground’s cooling effect will be enhanced with the additional use of rainwater, by evapotranspiration. Furthermore, it is to be reusable for water games or school gardening too.
  • The increase of trees, school gardens, green walls and roofs and the shade they provide will also help to locally temper with heat waves. Moreover, several vegetable gardens should contribute as well to the children’s environmental awareness.
  • Artificial installations are integrated to renaturation project, for shade houses will punctually supplement the other infrastructures. Combined with various cooling techniques and kinetic energy collection infrastructures on playgrounds, they are aimed at cooling down schools and reducing their energy consumption.

Transferability of the result

The results of this programme can be transposed to cities who want to:

  • Adapt cities to climate change by an urban and natural development:
    • Choose urban development considering NBS for social and climate challenges o Anticipate the evolution of urban infrastructure: consider NBS in face of repeated heat waves
  • Organize a participative management

Lessons learned

Process:

  • Integrated vision in response to various urban vulnerabilities
  • Inclusive approach of residents, public institutions and private sector
  • Share ideas and innovations from their cities

Objectives:

  • Ability to think systemically in order to multiply the benefits
  • Flexibility: natural and modular spaces and facilities capable of accommodating uses

Financing

The Municipality of Paris funds the project.
