The project ‘Planting the Future and Cultivating Life’ aims to create an ecological corridor in the city by reforesting an area of 28 hectares, under the direction of the Porto Velho City Council. It encourages citizen participation in tree planting activities or the management of green areas. To this end, the municipality is carrying out tree planting programmes in parks, squares and along public roads, encouraging citizens to get involved in this endeavour by actively participating in tree planting actions, caring for trees already on their property or raising awareness of the importance of these actions. (1) They seek to involve organisations such as schools, colleges, companies, associations and public organisations to increase the community's and young people's interest in responsible practices and positive attitudes to value and preserve the environment (1). To achieve this goal, the Porto Velho city council organised a tree-planting day on October 23rd 2023, where 31,000 tree seedlings of native and fruit trees were planted in the Park Passarela Espaço Alternativo (1, 7). This was done with the support of the Municipal Secretariat of Environment and Development (1). This activity is part of the project Virada Ambiental, which seeks to promote the planting of native trees in municipalities across the country, raising awareness of the importance of planting native species and training municipal civil servants and the general public (3, 5). The National Confederation of Municipalities also supports this project and aims to mobilise society to encourage the planting of native trees to rescue biodiversity and recover environmental services, favouring social welfare by promoting tourism, and outdoor sports activities (6), providing shade, protecting the soil and combating high temperatures (2).

Project objectives

- To sensitise and encourage the community to engage in environmental preservation (1) and conservation of natural resources (3) - To build a more sustainable and greener city, through afforestation programmes in parks, squares and public roads (1) - To create green areas as a way of protecting the environment (1) - To raise environmental awareness in Porto Velho (2) - Contributes positively to the quality of life of the population, providing shade, protecting the soil and combating high temperatures (2)

Implementation activities

A planting day was organised to support the creation of a biological corridor in the city in the Park Alternative Space. This activity is part of the implementation of afforestation programmes in parks, squares and public roads (1). All citizens were encouraged to participate in this effort by planting trees, caring for those already on their property or making others aware of the importance of this act (1). Thus, 31,000 tree seedlings were planted during the mobilisation, to set a world planting record (1, 2). On the other hand, partnerships have been sought with organisations such as schools, colleges, companies, associations and public bodies (1). As part of the Virada Ambiental project, they mention that in addition to filling out the registration form to carry out reforestation activities, the municipality is required to commit to registering each planting action in the Plante Go app, available for Android and iOS (5).
