Record temperatures and the multiplication of extreme climatic events are causing considerable loss of human life, as well as the destruction of infrastructure, production and ecosystems.
Adaptation therefore seems a necessity. However, adaptation policies are accused of diverting efforts and investments that could be better used to reduce CO2 emissions, and even of contributing to an increase in these emissions.
Contrary to these positions, this book emphasizes that, far from being opposites, adaptation and mitigation are complementary: adaptation makes it possible to deal with emergencies and provides local solutions, while mitigation acts over the long term and benefits the planet as a whole.
Starting with concrete measures (air conditioning, revegetation, dykes, water management, etc.), the authors analyze their effectiveness and cost. They show how public authorities can support them to avoid maladaptation and protect the most vulnerable.
A plea to understand adaptation not as a failure, but as a reason to hope.
