This article envisions urban agriculture as a solution to address global warming by decreasing the urban heat island effect while also addressing many other urban sustainability issues, such as multi-functionality, creating new commons, amenities and ecosystem services, reinventing urbanity, encouraging community building by growing local food, and enhanced water management. This article examines how urban design and planning can promote this solution to reconfigure more sustainable and resilient cities. A crucial aspect is that urban planning should evolve from its traditional prescriptive form to adaptive planning. An important point in adaptive planning is that anybody concerned should be associated with the decision-making process, which requires the involvement of citizens in the decisions that affect them.
May urban agriculture be the cornerstone that helps reconfigure more sustainable cities and if so, under which conditions? And if so, what type of urban agriculture? Such are the two issues underlying this article. Why not counteracting urban sprawl by fostering what could be called "rural sprawl", by introducing nature and rural characteristics such as farming within the city, in its interstitial areas and wastelands? In this perspective, urban agriculture becomes a common good, bringing people together and reshaping the whole urban fabric that would eventually propose a radical remaking of the urban. Urban agriculture lends particularly well to long-lasting urban policies, especially those turning environmental "bads"-such as brownfields and wastelands-into environmental "goods" and urban amenities. Urban agriculture in interstitial abandoned urban areas may be one of cities' main seedbeds of creative innovation. It is all about the right to decide and the power to create, renewing and deepening what Henri Lefebvre called The Right to the City.
LA VILLE DURABLE EST-ELLE SOLUBLE DANS LE CHANGEMENT CLIMATIQUE?François MANCEBO RÉSUMÉ Le changement climatique est une préoccupation ayant émergé récemment dans le champ du développement durable. Les espaces urbains jouent un rôle majeur dans l'inclusion des impératifs du changement climatique au coeur de la ville durable, mais le risque, qui commence à se vérifier, est que les politiques urbaines durables se réduisent à la composante climatique, au détriment de questions aussi importantes que les conditions de vie ou les inégalités environnementales, par exemple. Est-il possible de remédier à cette situation et, si oui, selon quelles règles et quels arbitrages?MOTS-CLÉS Ville durable, écoquartier, changement climatique, arbitrage, aménagement urbain ABSTRACT Climate change is a growing concern in sustainable development circles. A number of reports have pointed to the danger that, while making the case for considering the built form as a major focus of the sustainable city to ensure compliance with climate change requirements, other important policy areas such as improving living conditions or tackling environmental inequalities are left out of the agenda. Can actions be applied to address this situation and if so, under which regulatory framework and arbitration agreement?
