Making an alliance with nature

When vegetation helps us take care of the climate


When solutions come from plants

The French insurance federation estimates the effect of climate change by 2040 at €92bn, to which must be added the cost of reduced economic activity.

According to one of the CCR scenarios by 2050, the cost of natural disasters would increase by 50%. A group of experts from the CNFPT ensures vigilance on the consequences of the climate crisis. These will be protean and will affect many sectors of our lives. But, it is possible to react to these consequences by making choices, by training ourselves and by planning our public spaces differently. Everyone is concerned, not just the people in charge. Many solutions come from a new relationship with the plant world.

Energy issues

It is a matter of experimenting when possible with new forms of solar energy, but also new modes of financing involving citizens to promote collective self-consumption. This will require new economic models more sense of innovation and collaboration. The biogas obtained by fermentation of organic matter is an extraordinary opportunity.

MOOC Renewable Energy

Cleanliness issues

With the effects of heat waves, odors , inconveniences will increase, but with the floods the floods will leave even more waste, the rehabilitation of the banks passes the again by the strength of the vegetation and the roots capable of containing multiple forms of erosion . The water can also be filtered by rose gardens improving the quality of treatments in a natural way.

Not to mention the increase in demonstrations and social outbursts that add to the workload of public agents who will increase on these points. Improving collection methods and reinforcing individual actions are essential to maintain a healthy public space. The development of compost can reduce a portion of waste.

MOOC Sanitation Techniques

Urbanism and habitat

The continuous artificialization of soils opposes the vegetation necessary to bring freshness. Politicians can/should make zero artificialization choices to safeguard food lands and fight against flooding, citizens are also invited to strive towards this goal in habitat and development choices. For citizens, the number one issue is the energy renovation of their homes to achieve carbon neutrality by 2050.

But the most fragile will have to be helped to avoid increasing precariousness. Urban space is increasingly becoming a co-production with a variety of public, private, resident, financial etc. actors. The challenge is for everyone to share the ambition of an economical, healthy, inclusive and resilient city. This passes according to the analyses of the CNFPT by:

  • Saving natural resources (energy, air, water, climate, materials, biodiversity);
  • Favoring social equity (fight against exclusion, poverty, access to housing ...);
  • Coping with risks (floods ...);
  • Favoring alternative mobilities to the car;
  • Favoring social, functional and inter-generational mixes: New ways of living (temporary housing, scalable, participatory housing ...)
  • Fight against global warming.

These issues require the development of a real engineering combining the social and the plant, a better evaluation of what is done and an ability to seize societal developments. Probably a need for collaborative public innovation.

MOOC Sustainable Building

Water and sanitation

With climate change, at the same time are to be anticipated flood risks and drought risks. The effects to be expected are a rise in coastal features, the development of invasive species, increased pollution and lack of drinking water.

Without water conservation, biodiversity will further decline. Furthermore, the increase in water pollution will generate health consequences. Inhabitants will need to be better informed of the effects and prevention actions undertaken as well as crisis management skills must be developed to deal with rising eco-anxiety (risk of ecological burn-out).

At the same time, practices of desartificialisation and desealing of the city are to be developed in public services, or even of rainwater management. It is necessary to continue the projects of renaturation and protection of wetlands while taking care of tiger mosquito invasions.

Knowledge of pollutants would also benefit from progress to protect water resources. There is probably a lack of knowledge on citizen participation in global issues and better sharing of knowledge and feedback.

MOOC water management


One of the key issues lies in the protection of fertile soils (brown screen) that participate in carbon storage, wetlands and canopy development in cities. The complexity of achieving these issues is to combine public policies with very different professional cultures.

The adaptation of the plant palette is already underway and must be combined with reasoned watering management. In the city the use of green waste is to be favored as well as the preventive fight against invasive exotic pests or invaders.

MOOC Biodiversity

Collective catering

For a country like France, collective catering would represent a 24% improvement in greenhouse gas emissions and a reduction in chronic diseases linked to poor eating habits.

The food issue is therefore important for health and climate. The solution probably lies in a relocalization of food, more use of plant proteins in our meals, the integration of vegetarian menus and favoring raw foods over home assembly cooking and sustainable farming practices.

MOOC Food Wasting

Building, Architecture, Roads and Transportation

Public policies are intersecting rehabilitation issues and adaptation to change. Roads and infrastructures will also have to integrate climate issues by incorporating green webs and revegetation.

The effects of air conditioning systems rejecting heat towards public spaces is also to be controlled. Mobility would benefit from more integrated approaches, which requires rethinking land-use planning, including in cross-border living areas. The transport sector is a particular emitter of greenhouse gases and should therefore be prioritized, in particular to avoid autosolism (all alone in one's car, in the city).

MOOC Mobility 3.0

Management and sustainable finance

Executives must be at the forefront of climate issues and learn to work collaboratively and transversally. New know-how will have to be built to mobilize and involve citizens: participatory budgets, socio-financing, responsible finance. Managers will also have to be attentive to the exposure of workers to hot extremes that lead to a decrease in vigilance and an additional risk of occupational accidents, but also to new risks and new fire interventions, network repairs, or degradation of the production tool.

MOOC Climate: a challenge for finance

Awareness and action

One of the consequences of Unaforis or Santé Publique France climate change to be expected is worsening social inequalities. Allied with a health crisis this can become explosive.

The urgency remains to educate as many people as possible to anticipate the issues. The climate festival is a wonderful opportunity to create links between citizens invited to train each other. It allows us to rediscover an alliance with the plant that is our best outcome.
