“…Esta falta de homogeneización tiene consecuencias metodológicas para la contabilización de áreas y sus superficies; es frecuente encontrar discrepancias en los datos incluso para una misma ciudad. En el caso de Xalapa, Falfán et al (2018) y Von Thaden et al (2021) reportan 37.2 % y 45 %, respectivamente, de cobertura vegetal y espacios verdes para Xalapa; con diferencias conceptuales, metodológicas, temporales y espaciales que contrastan ampliamente con los resultados de este estudio, en el que se calculó una cobertura de 14.04 %.…”

“…Es importante señalar que existen otros espacios verdes, públicos y privados, en la ciudad de Xalapa (Falfán et al, 2018;Von Thaden et al, 2021), no considerados en el sistema de áreas verdes aquí analizado, los cuales desempeñan un papel importante en la provisión de servicios ecosistémicos a la población y que pudieran estar contribuyendo a disminuir la injusticia ambiental distributiva en esta ciudad.…”

Las áreas verdes proporcionan beneficios y servicios ambientales y sociales a la población, sin embargo, generalmente, se distribuyen heterogéneamente en las ciudades, ligado a un aprovisionamiento desigual de tales beneficios, con implicaciones de justicia ambiental. Con base en un análisis cartográfico y estadístico, se evaluó la dotación y distribución espacial de las áreas verdes urbanas públicas en Xalapa, México, así como su relación con el Índice de Marginación Urbana del Consejo Nacional de Población. En Xalapa, la distribución de las áreas verdes mostró un patrón agrupado; el 47 % de las colonias de la ciudad no cuentan con áreas verdes y la menor dotación y superficie de áreas verdes estuvieron relacionadas con altos índices de marginación. Como en muchas otras ciudades en México, lo anterior constituye un indicio de una falta de justicia ambiental distributiva en la ciudad, así como de una necesidad de planteamientos de diseño y rediseño viables para el alcance de una dotación menos heterogénea de áreas verdes en la ciudad.

“…In this context, urban green areas are important refuges for biodiversity 30 , 31 that mitigate the effects of climate change 32 – 34 . Since there are different types of urban greening 35 , monitoring the dynamics of green spaces is an important prerequisite for improving sustainable urban planning and making it compatible with the conservation of heritage building.…”

Urban green areas minimize the negative effects of climatic change and improve the sustainability of historic cities. Despite this, green areas have traditionally been considered a threat to heritage buildings because they cause humidity changes, that accelerate degradation processes. Within this context, this study evaluates the trends in the inclusion of green areas in historic cities and the effects it causes on humidity and conservation of earthen fortifications. To achieve this goal, vegetative and humidity information has been obtained since 1985 from Landsat satellite images. The historical series of images has been statistically analysed in Google Earth Engine to obtain maps that show the means, 25th, and 75th percentiles of the variations registered in the last 35 years. The results allow visualizing spatial patterns and plotting the seasonal and monthly variations. In the decision-making process, the proposed method allows to monitor whether the presence of vegetation is an environmental degradation agent in the nearby earthen fortifications.The analysis of the historic fortified cities of Seville and Niebla (Spain) shows a gradual increase in green areas and an interest in locating them near the earthen fortifications. The impact on the fortifications is specific to each type of vegetation and can be positive or negative. In general, the low humidity registered indicates low danger, and the presence of green areas favours drying after heavy rains. This study suggests that increasing green spaces to historic cities does not necessarily endanger the preservation of earthen fortifications. Instead, managing both heritage sites and urban green areas together can encourage outdoor cultural activities, reduce the impacts of climate change, and enhance the sustainability of historic cities.

“…'Landscape connectivity' relates to biodiversity conservation [1] or deals with ecosystem stability [2] and loss of natural habitat [3]. However, as urbanization is increasing habitat fragmentation, urban and rural landscapes are changing uses and new landscape patterns are being created [4][5][6]. The unregulated growth in density of urban population results in landscape fragmentation [7] and even though green spaces provide a home for biodiversity this is not addressed in a holistic way within the scale of our cities or regions.…”

Contribution of Conceptual-Drawing Methods to Raise Awareness on Landscape Connectivity: Socio-Environmental Analysis in the Regional Context of Trentino (Italy)

This paper deals with landscape understanding and connectivity from an ecological as well as a human perspective. It is based on a broader research study known as EIT Climate-KIC SATURN (System and sustainable Approach to virTuous interaction of Urban and Rural LaNdscapes) co-funded by the European Institute of Innovation & Technology (EIT), Climate-KIC and the institutions participating in this project. The aim of the study was to explore how landscape connectivity is perceived, on urban and regional scales, by decision-makers and key stakeholders as well as the impact this can have on building sustainable cities. The paper used a series of drawing and visualization workshops, community engagement methods, and participatory tools to identify the connection communities and decision-makers have with their landscape surroundings as well as the impact landscape connectivity has on our health and wellbeing. Through a series of specifically designed workshops following a landscape visioning approach, the paper explored how drawings and visualizations can support decision-makers to create a vision that addresses landscape connectivity, considering the socio-ecological factors in their area and creating a holistic regional approach between urban and rural landscapes. The study concludes that landscape connectivity is of major importance when creating visions for a sustainable future; however, a better connection between ecological and human elements needs to be established to improve landscape design.
