Resumen: La rapidez en el crecimiento de nuestras ciudades y municipios, y el aumento vertiginoso en la demanda de suelo urbanizable, ha originado la impermeabilización del suelo urbanizado, lo que ha producido un aumento en los caudales de escorrentía. Por otro lado, el cambio climático impone nuevos desafíos en materia de gestión del drenaje pluvial para nuestras ciudades y municipios. El municipio de Turbaco vive una problemática en materia de drenaje pluvial, por causa del aumento en la demanda de suelo urbanizable y por la impermeabilización del suelo urbanizado. Los embalses de retención y las canales verdes surgen como una alternativa para la gestión de las aguas pluviales. Estos sistemas son de fácil adaptación al medio y son soluciones que van en favor del medio ambiente, al tiempo que constituyen parte del paisaje urbano. ___Palabras clave: Inundaciones, embalses, canales verdes, análisis hidrológico, planificación urbana. ___Abstract: The rapid growth of our cities and municipalities, and the rapid increase in the demand for urbanizable land, has led to the waterproofing of urbanized land, which has led to an increase in runoff flows. On the other hand, climate change imposes new challenges in the management of storm drainage for our cities and municipalities. The municipality of Turbaco lives a problem in the matter of rainwater drainage, due to the increase in the demand of urbanizable land and the waterproofing of the urbanized land. Retention reservoirs and green channels emerge as an alternative to stormwater management. These systems are easy to adapt to the environment and are solutions that are in favor of the environment, while being part of the urban landscape. ___Keywords: Floods, reservoirs, green channels, hydrological analysis, urban planning. ___Recibido: 13 abril 2016.

This study proposes the concept of urban wet-landscapes (loosely-defined wetlands) as against dry-landscapes (mainly impervious surfaces). The study is to examine whether the dynamics of urban wet-landscapes is a sensitive indicator of the coupled effects of the two major driving forces of urban landscape change – human built-up impact and climate (precipitation) variation. Using a series of satellite images, the study was conducted in the Kansas City metropolitan area of the United States. A rule-based classification algorithm was developed to identify fine-scale, hidden wetlands that could not be appropriately detected based on their spectral differentiability by a traditional image classification. The spatial analyses of wetland changes were implemented at the scales of metropolitan, watershed, and sub-watershed as well as based on the size of surface water bodies in order to reveal urban wetland change trends in relation to the driving forces. The study identified that wet-landscape dynamics varied in trend and magnitude from the metropolitan, watersheds, to sub-watersheds. The study also found that increased precipitation in the region in the past decades swelled larger wetlands in particular while smaller wetlands decreased mainly due to human development activities. These findings suggest that wet-landscapes, as against the dry-landscapes, can be a more effective indicator of the coupled effects of human impact and climate change.

The importance of trees for an invasive Mediterranean cellar slug, Limacus flavus , was studied within one block of a residential area in Kyiv city (Central Ukraine) from spring of 2020 to spring of 2021. Slugs tended to occur in the old poplars ( Populus nigra var. italica ). Live animals or their traces were found on the 71 of 320 poplars and on 17 trees of other species in the studied area. Slugs often go up to at least 12 m above the ground on these poplars and feed on the lichens there. Animals breed and spend the daytime inside at least some of these trees under the bark. Slugs were wintering in some of these trees in 2020-2021 and probably also at least in 2019-2020, while previously L. flavus was reported from Eastern Europe only in connection to cellars, basements and greenhouses. Apparently these slugs are occupying additional habitats in response to climate change and their occurrence in the trees may become common in Eastern Europe with the warming of climate. The colouration of L. flavus and closely related L. maculatus is discussed. Various differences of the colouration were suggested in the literature to distinguish the two species, most notably the central light stripe on the back of L. flavus , but this character is absent in most of the studied specimens and, therefore, the overall colouration overlaps in the studied populations of the two species.

Purpose Urban landscapes play a significant role in supporting municipal, ecological and social systems. Besides, valuable environmental services and urban green spaces provide social and psychological services, very important for the liveability of modern cities and the well-being of urban residents. It is clear that the area of green space in a city, the method of designing urban landscape and access to urban green space potentially affect the health, happiness, comfort, safety and security of urban dwellers. Urban landscape plays a significant role in providing habitats for wildlife, and an important vegetation type in doing this is species-rich herbaceous vegetation that provides pollen and nectar plus physical habitat for native fauna. Any factor that makes an impression on the urban landscape (such as climate change) will affect people’s lives directly or indirectly. There is a universal consensus that the temperature has increased in most of the world over the past century the investigation of climate change impacts on the urban landscape is the purpose of this study. Findings Understanding the process of climate change adaptation is necessary to design plant communities for use in public landscapes. Increased CO2 and air temperature in conjunction with the changing rainfall conditions, as the three important factors of climate change, potentially alter almost all world ecosystems. Climate change provides new opportunities, and in some cases, an obligate need to use non-native plant species in conjunction with native plant species, not only to reduce the side effects of climate change but also to increase the species diversity and aesthetic value in meadow-like naturalistic planting design. Originality/value The authors confirm that this work is original and has not been published elsewhere. In this paper, the authors report on the effects of climate change on urban landscape and suggest different kind of solutions to reduce the effects. The paper should be of interest to readers in the areas of landscape architecture, landscape ecologist, landscape planner, landscape managers and environmental designer.

The culture of urban space design is not separate from the uncanny nature of climate change, even though this latter now appears more threatening than the production of risks or new vulnerabilities. Environmental disasters and cities’ high degree of exposure to these risks are well known. What is apparent is the close relationship between these disasters and the urban transformations generated by approaches which, quoting the writer Amitav Gohsh, can be defined as outcomes of the Great Derangement Era. Through our research and design project; we have outlined the need to break free from the uncanny feeling caused by the specific phenomena which make territories more fragile and vulnerable to extreme weather and climate events. The design process illustrated, which involved a small town in central-western Sardinia, is an example of how the construction of a new urban landscape and architecture can take place starting, not only from the contingent risks of emergency situations, but rather from the recognition of any potential risks. With the goal of setting up an open and sustainable territorial plan, the case study has been designed as an approach to climate adaptation even if in Sardinia the link between climate change and flood risk has not been studied in depth and no evidence of this link has yet emerged. The project scenarios of an urban plan for one of the local governments in Sardinia, highlighted in the paper, has been conceived as a path of coevolution between new urban transformations and ecological dynamics of the environment.
