Planejamento da arborização urbana: estudo de caso da Avenida Duque de Caxias, São Lourenço da Mata - PE

Abstract

This study focused on urban tree planning along Duque de Caxias Avenue, considering its feasibility and associated costs. The objective was to evaluate the physical conditions of the road and specific challenges, following the guidelines of the Urban Tree Planting Manual of Recife. Small-sized species suitable for sidewalk widths and wire heights were selected, essential to mitigate risks and reduce seedling mortality rates. The methodology included a detailed survey of available planting spaces, identifying 179 viable intervals, albeit limited by the scattered presence of urban elements such as poles and signage boards. The results highlighted the need for 2130 seedlings to cover the planned demand, considering a mortality rate of 50%. Cost assessments from nine local nurseries revealed budgets ranging from R$ 383,400.00 to R$ 440,200.00, emphasizing the complexity and economic challenges associated with acquiring seedlings in a region with scarce available native species. Additionally, a significant gap was identified in the supply of native species seedlings in local nurseries, underscoring the importance of effective policies for urban biodiversity conservation and encouragement of local seedling production. It is concluded that integrated and participatory planning is crucial for the success of urban tree planting initiatives, actively involving local communities, government agencies, and research institutions. This approach not only contributes to improving urban quality of life but also strengthens city resilience in the face of environmental challenges. This study not only provides relevant information for the practical implementation of urban tree planting projects but also highlights the ongoing need for adaptation and innovation in urban policies to promote greener and more sustainable urban environments aligned with sustainable development goals.
