La liste préventive des espèces exotiques envahissantes de Wallis et Futuna a été créée en 2024 par une révision de la règlementation, à la suite d'une prestation d’une biologiste, et de la consultation d’associations et de services du territoire. Elle répertorie 123 espèces absentes du territoire mais présentes dans la région et dont Wallis et Futuna entend se préserver. Le document compile des fiches techniques de reconnaissance et de gestion des 123 espèces figurant sur la liste préventive, relatives aux milieux terrestres, humides et de rivières et marins. Le document détaille également les 6 étapes du plan d'intervention rapide élaboré pour répondre aux introductions d'espèces exotiques envahissantes à Wallis et Futuna : (i) réceptionner le signalement, et collecter les informations; (ii) confirmer l'identification de l'espèce; (iii) améliorer la connaissance sur la répartition de l'espèce; (iv) évaluer la situation et choisir l'option de gestion; (v) élaborer et mettre en place un plan d'intervention et (vi) veiller.

Reflect on the present, on the dynamics and the conditions that built it, and look forward at the same time, in search of a prospect to improve the future. Since Howard (1850–1928) and Geddes (1854–1932), this has been the dominant logic supporting the work of all those (architects, urban planners, planners, landscape architects, etc.) who grappled with city and territorial management and planning. However, from the 1970s, territorial planning has been confronted with new concepts – such as sustainable development, environmental sustainability and social equity – and more recently, new challenges – such as the ones linked to climate change, which led to the need to redefine territorial planning in disciplinary and operational terms. For some years now, the planner’s new role is under discussion, especially in relation to the challenges posed by climate change. Sustainability, mitigation, adaptation, renewable energy, low-carbon transition, ecosystem approach and post-disaster planning are just some of the new keywords surrounding the discussion on territorial management and planning. This chapter aims to present rationally, what it means to re-organize and re-think the city, in a long-term perspective. It wants to show how it is possible, and above all is a duty to integrate the new concepts mentioned above in urban planning, to deal with the effects of climate change. The Urban Heat Islands contrast enters fully into the feasible experimentation with appropriate innovations in territorial planning. The paper draws attention to the Italian situation, in the light of the European reference framework.
