Apr\u00e8s avoir pass\u00e9 la derni\u00e8re semaine \u00e0 enqu\u00eater sur la strat\u00e9gie foresti\u00e8re urbaine de notre ville, j’ai d\u00e9couvert un r\u00e9seau complexe de d\u00e9fis climatiques, de probl\u00e8mes de financement et d’obstacles \u00e0 la mise en \u0153uvre qui m\u00e9ritent une attention particuli\u00e8re.<\/p>\n

Les chiffres racontent une histoire pr\u00e9occupante. Calgary maintient actuellement environ 8,25%<\/b> de couverture de canop\u00e9e d’arbres selon la derni\u00e8re \u00e9valuation environnementale de la ville \u2013 nous pla\u00e7ant consid\u00e9rablement derri\u00e8re des villes nord-am\u00e9ricaines comparables. Edmonton est \u00e0 13,4%<\/b>, tandis que Toronto affiche pr\u00e8s de 28%<\/b> de couverture. L’objectif de notre ville d’atteindre 16%<\/b> d’ici 2033 repr\u00e9sente l’un des projets de foresterie urbaine les plus ambitieux de l’ouest canadien.<\/p>\n

\u00ab\u00a0Nous essayons essentiellement de cr\u00e9er un syst\u00e8me d’infrastructure vivante dans l’un des climats de prairie les plus difficiles du pays,\u00a0\u00bb explique Jeanette Wheeler, coordinatrice de la foresterie urbaine pour la Ville de Calgary<\/a>. \u00ab\u00a0Il ne s’agit pas seulement d’esth\u00e9tique \u2013 c’est une question de r\u00e9silience climatique tout en am\u00e9liorant la qualit\u00e9 de vie.\u00a0\u00bb<\/p>\n

Les avantages vont bien au-del\u00e0 du simple embellissement. Des \u00e9tudes de l’Universit\u00e9 de Calgary<\/a> sugg\u00e8rent que des for\u00eats urbaines correctement implant\u00e9es peuvent r\u00e9duire les temp\u00e9ratures urbaines jusqu’\u00e0 4\u00b0C pendant les mois d’\u00e9t\u00e9, diminuer les co\u00fbts \u00e9nerg\u00e9tiques r\u00e9sidentiels d’environ 7-11%, et am\u00e9liorer consid\u00e9rablement la sant\u00e9 mentale des r\u00e9sidents vivant \u00e0 moins de 300 m\u00e8tres d’espaces verts.<\/p>\n

Ce qui rend la situation de Calgary particuli\u00e8rement difficile, c’est notre climat unique. Contrairement aux villes des r\u00e9gions plus temp\u00e9r\u00e9es, nos arbres font face \u00e0 des fluctuations extr\u00eames de temp\u00e9rature, des p\u00e9riodes de s\u00e9cheresse prolong\u00e9es, et ces fameux vents chinook qui peuvent stresser m\u00eame les arbres bien \u00e9tablis.<\/p>\n

\u00ab\u00a0Le processus de s\u00e9lection pour les arbres adapt\u00e9s \u00e0 Calgary n\u00e9cessite une incroyable pr\u00e9cision,\u00a0\u00bb note Dr. Marcus Chen, chercheur en \u00e9cologie urbaine \u00e0 l’Universit\u00e9 Mount Royal<\/a>. \u00ab\u00a0Nous examinons de plus en plus des esp\u00e8ces qui peuvent g\u00e9rer \u00e0 la fois les conditions actuelles et les changements climatiques pr\u00e9vus pour les 30-50 prochaines ann\u00e9es. C’est une cible mouvante.\u00a0\u00bb<\/p>\n

Lors de ma conversation avec le surintendant des parcs Ravi Sekhon, la r\u00e9alit\u00e9 financi\u00e8re est devenue plus claire. \u00ab\u00a0L’allocation actuelle de 40 millions de dollars<\/b> pour l’expansion de la canop\u00e9e urbaine repr\u00e9sente moins de la moiti\u00e9 de ce que des villes comparables investissent par habitant,\u00a0\u00bb a expliqu\u00e9 Sekhon lors de notre visite des nouveaux sites de plantation de Montgomery. \u00ab\u00a0Nous progressons, mais le calendrier pourrait s’av\u00e9rer ambitieux sans engagement suppl\u00e9mentaire.\u00a0\u00bb<\/p>\n

Les implications \u00e9conomiques vont au-del\u00e0 des budgets municipaux. Les propri\u00e9t\u00e9s avec des arbres matures se vendent 7-15%<\/b> plus cher que des propri\u00e9t\u00e9s comparables sans couverture d’arbres significative, selon le Calgary Real Estate Board<\/a>. Parall\u00e8lement, les entreprises dans les zones commerciales bien arbor\u00e9es rapportent une satisfaction client sup\u00e9rieure de 12%<\/p>\n","protected":false},"excerpt":{"rendered":"
