Rising temperatures and increasingly frequent heat waves have brought the issue to the forefront need to increase urban vegetation, especially through the planting of trees and shrubs. This phenomenon, which affects many Spanish and Latin American cities, has prompted neighborhood associations, environmental experts, and public administrations to call for and implement various initiatives to strengthen green spaces and mitigate the effects of climate change.
In neighborhoods with scarcity of trees, residents are experiencing days marked by stifling heat, which has led to demonstrations to demand a increase in trees, shrubs and plants in urban areas. It highlights how the lack of vegetation turns the cement and asphalt environments into "true ovens" and particularly exposes the most vulnerable groups, such as the elderly, people with health problems or at risk of social exclusion.
Municipal projects and large-scale reforestation
In response to this problem, several city councils are carrying out ambitious reforestation plansThis is the case of Alcalá de Guadaíra, in Seville, where the Pinar de Oromana has been the protagonist of a comprehensive action that includes the planting of more than 1.500 trees and 500 shrubs This year alone, as part of a plan to reach 5.000 trees and 10.000 shrubs by 2027. Local authorities emphasize that native and more resistant species, such as hackberry trees, holm oaks and cork oaks, are being chosen to ensure their survival and strengthen the biodiversity of the local ecosystem.
These measures are accompanied by maintenance, pest control, pruning, and irrigation, as well as the removal of dead trees due to drought or disease. Municipal officials emphasize that the citizen collaboration and the involvement of educational centers They are fundamental in these campaigns, which seek to transform green spaces into places of coexistence and well-being.
Social awareness and institutional commitment to urban vegetation
The advance of climate change is also driving actions from universities and public organizationsAt José Martí University in Colima, a reforestation campaign was held, involving the entire educational community in planting trees and shrubs specially selected for the local environment. More than 300 species were planted, promoting not only the improvement of the landscape and ecological infrastructure, but also the environmental education and social responsibility, values that are considered essential to face the challenges of the future.
Other examples can be found in Peru, where the army and different organizations collaborate to increase the number of trees and shrubs on military fields, with the goal of creating healthy spaces and contributing to air quality and thermal regulation. These initiatives are often accompanied by technical advice to ensure the appropriate selection of species and proper maintenance, crucial aspects for these actions to have lasting and positive effects.
Restoration and the role of soil and vegetation experts
The importance of trees and shrubs is not limited to their aesthetic or shade function. Experts in biology and soil conservation are carrying out restoration projects in degraded areas, as seen in the Cofre de Perote region. In these cases, the revegetation with shrubs, herbaceous plants and trees It is vital to prevent erosion and restore soils that have lost their vegetation cover. Techniques such as nursery propagation and planting during the rainy season are used, adapting the intervention to the conditions of each plot to achieve sustainable development.
Specialists emphasize that, depending on the degree of soil deterioration, costly mechanical interventions may be necessary, but they should always be combined with the gradual introduction of native species to create various layers of vegetation, from grasses to shrubs and eventually trees.
Urban challenges: management, maintenance and controversies
In some cities, the increase in trees and shrubs coexists with controversy over the necessary logging for safety reasons or to allow for new infrastructure. Municipal governments argue that The withdrawal of specimens is always carried out for justified reasons, such as avoiding risks to citizens or accommodating public works. However, there is pressure to replenish them quickly and to focus on species that contribute to urban biodiversity.
In recent cases, such as that of Zaragoza, millions of euros have been invested in the creation and improvement of green spaces, planting tens of thousands of trees and shrubs in different areas of the city. However, the community remains vigilant about the balance between tree conservation and urban development, insisting that Urban trees and shrubs are essential for health and quality of life.
The fight against the use of products such as glyphosate, considered harmful to both the environment and human health, is another neighborhood demand. Associations emphasize the importance of comply with environmental regulations and seek alternative methods of maintaining green areas.
The testimonies of neighbors and experts make it clear that urban vegetation Not only do trees provide shade and beauty to public spaces, but they are also a key element in regulating temperature, preserving biodiversity, and reducing the risks associated with climate change. Collaboration between institutions, citizens, and specialists demonstrates a collective awareness of the value of trees and shrubs, although the path to achieving greener and healthier cities is still underway.
