“…This result could be related to the reduction of forest cover and degradation of tropical landscapes in peri-urban areas, since this climatic domain, contrary to temperate and boreal regions, continues to show a trend of forest loss, or it could also be associated with the average resolution of forest cover data [81]. Possibly, the relationship between forest cover and urban expansion would improve with highresolution spatial and spectral data that would allow a ner analysis of urban and peri-urban tree cover [32], [82],…”

Urban expansion and contemporary climate variations are caused by different proximate and underlying multidimensional factors. A spatiotemporal analysis of the urban socio-ecosystem generates key information for planning a sustainable urban model. We analyzed the spatiotemporal pattern of urban expansion and maximum temperature variations in a hierarchy of four categories of cities in the South American tropics in a sequence of seven-time intervals between 1985 and 2018. We defined the boundaries of 31 cities using spatiotemporal information on climatic, topographic, forest, demographic, and economic dimensions. This information was used to run several linear and nonlinear models that would explain the pattern of urban expansion and maximum temperature variations. We found that the historical pattern of expansion varied over time by city category; however, by the end of the first two decades of the 21st century, expansion was significantly higher for all categories. All dimensions contributed to explaining the expansion. An increasing altitude, the steepness of the slope, and a lower roughness index were the proximate causes of increasing the probability of city expansion; on the contrary, vegetation cover had the least importance, suggesting degradation of peripheral ecosystems. Underlying causes, an increase in the gross domestic product (GDP), and demographic variations were of high importance in explaining the probability of expansion in the region. We suggest that the systematic transition from peri-urban soil to impervious cover in the South American tropics is key to both local and global land surface energy balance.

“…Economically disadvantaged communities in neighbourhoods with poor access to green spaces are known to be burdened with health issues more, leading to intergenerational well-being problems ( Sharifi et al, 2021 ). Researchers have proven that urban green spaces may improve human health and well-being and are meeting spaces for various socioeconomic classes, reducing segregation and multiplying opportunities for the psychological restoration of residents ( Liotta et al, 2020 , Aerts et al, 2021 , Spencer et al, 2020 , Bonilla-Bedoya et al, 2020 ). Living close to high-quality urban green spaces is associated with positive impacts on health, both physical and mental ( Europe, 2016 ).…”

The impact of the COVID-19 pandemic on the importance of urban green spaces to the public

Green spaces provide people with countless intangible benefits, particularly important during crises. Restrictions imposed in many countries due to the COVID-19 pandemic forced people to maintain social distance, limit travels, and even refrain from visiting green spaces and stay at home at a certain point. The survey in one of the largest cities in Poland, Kraków, was intended to help understand the impact of the pandemic on the importance of urban green spaces to the public. The study focused on the first three stages of the pandemic in Poland, from March to November 2020. Nine weeks of the survey yielded over 1,250 responses. Responses to spatial questions were analysed with GIS tools and geoprocessing algorithms. The number of visitors to green spaces during the pandemic fell to 78.9% of the population, which is down 13.1% compared to before the pandemic. At the same time, the percentage of people refraining from the visits fell with each phase of the crisis. According to the study, residents believed green spaces to be important for their mental and physical health. Over 75% of the participants considered visits to green spaces as having a very big or big impact on stress level reduction. The work provides empirical proof of the importance of green spaces to residents, particularly during a crisis. The results can affect urban spatial policies and management of green spaces and can potentially be applied in other cities.

“…La incorporación de especies nativas en áreas recreacionales puede ser una iniciativa que permita dar paso a la introducción de estas en jardines residenciales. En términos generales se ha evidenciado que los espacios verdes aportan positivamente a los habitantes del DMQ [42,43]. Aunque paisaje natural de Quito está totalmente fragmentado y deteriorado, la participación ciudadana y la inclusión social permitirían crear un Quito sustentable, con mayor cantidad de áreas verdes que puedan en un futuro conectarse con áreas verdes naturales.…”

INTRODUCCIÓN. El crecimiento de las ciudades ha afectado considerablemente los sistemas ecológicos, haciendo necesaria la creación de espacios verdes. La flora nativa es una buena opción para dichos espacios, debido al mínimo costo de mantenimiento, su adaptación a las temperaturas, precipitaciones y resistencia a plagas. OBJETIVO. Conocer la factibilidad del uso de plantas nativas como ornamentales en áreas urbanas del Distrito Metropolitano de Quito. Específicamente esperamos conocer la oferta y demanda de plantas ornamentales en el mercado. Y también queremos proponer especies nativas con potencial uso ornamental. MÉTODO. Se realizaron encuestas a comerciantes en Nayón acerca de las plantas que comercializan. Además, se realizaron consultas bibliográficas, entrevistas y visitas de campo para identificar las especies con potencial ornamental. RESULTADOS. Las plantas ornamentales exóticas son las que ocupan la mayor parte del mercado. Los comerciantes de plantas ornamentales por un lado no conocen cuales son las especies de plantas nativas, pero por el otro les otorgan características positivas. Presentamos una lista con 27 especies nativas con potencial ornamental. DISCUSIÓN Y CONCLUSIONES. Dadas sus características intrínsecas, así como el valor que se les dan a las plantas nativas, consideramos tienen potencial para ser utilizadas como ornamentales y formar parte del paisaje urbano.
