Effects of the features of contemporary occidental cities on urban avifauna
2022
Desde los primeros asentamientos humanos permanentes del Holoceno, hace 10 000 años, hasta las ciudades contemporáneas, las aves han cohabitado con los seres humanos. En las últimas décadas la urbanización ha crecido exponencialmente en el planeta y, en 2030, más del 60% de la población mundial vivirá en zonas urbanas. En función de su tolerancia a la urbanización las aves se clasifican en tres categorías: evitadoras, adaptadoras o explotadoras urbanas. Las ciudades occidentales contemporáneas atraen a las aves por la presencia de recursos tróficos abundantes y predecibles, la reducción en la diversidad de depredadores o la provisión de estructuras donde ubicar los nidos, entre otras. Sin e…
What future for decommissioned historic irrigation canals? Crafting new identities in the Lower Ter (Spain)
2020
Historic irrigation canals are valuable socioecological systems capable of delivering several ecological and cultural services. However, ecological modernisation initiatives are leaving decommissioned ditches in limbo. A case study strategy is used to analyse the history of a decommissioned 700-year-old canal network in northeastern Spain and the unexpected intervention of several stakeholders who have attempted to redefine the former canals through new uses. The study relies on the analysis of documents and eight semistructured interviews with key stakeholders. We argue that this case reflects a policy failure in the application of multifunctionality, integrative planning and social partic…
Socioekoloģiskās sistēmas pieeja pilsētas zaļās infrastruktūras plānošanā: Hunzes upes koridora piemērs Groningenā
2019
Pilsētu var uzskatīt par daudzšķautņainu organismu, kas pastāv pateicoties gan pilsētas ekosistēmas iekšējiem, gan arī ārējiem resursiem, taču pieaugot iedzīvotāju skaitam, noslogojums uz pilsētā pastāvošajām dabas teritorijām un kultūrmantojumu nemitīgi pieaug. Pilsētvide veidošanā tiek izmantoti stingri noteikti pārvaldības instrumenti, kā arī pilsētvides apsaimniekošanā tiek izmantoti tehniski pārvaldības risinājumi. Līdz ar to pilsētas kļūs par neelastīgām un izteikti cilvēku kontrolētām sistēmām, kuras zaudē spēju pielāgoties neprognozētu ārējo faktoru iedarbībai. Arī pilsētas kultūrvēsturiskās sejas zaudēšana atstāj nospiedumu uz vietas identitātes un labklājības jautājumiem. Tā iemes…
From the vestiges port at the port hybrid: the experimental field of the waterfront 2.0
2012
Il contributo si propone di riflettere criticamente sulla possibilità di piani, programmi e progetti di riqualificare gli spazi portuali e di waterfront alla luce delle mutate condizioni del trasporto marittimo e passeggeri e in riferimento al conflitto tra funzioni portuali che richiedono spazi sempre maggiori e la crescita consolidata della città in cui il porto è inserito. L'armoniosa coesistenza di due realtà indipendenti, una porta attiva e una città viva, si sta tentando di raggiungere non solo attraverso l'unità fisica, ma generando flussi e sinergie. Il contributo esamina le aree di waterfront come campo di sperimentazione per un approccio sostenibile alle trasformazioni del territo…
Green infrastructures for the energetic and environmental sustainability of cities
2019
The inexorable extension of urbanization is consuming huge amounts of soil drastically reducing natural vegetation, replacing it with buildings and low albedo surfaces. The changes due to the different thermal properties of surface materials and the lack of evapotranspiration in urban areas lead to a phenomenon known as "urban heat island effect". By reintroducing the vegetation back into the urban landscape, a partnership between nature and cities should be strengthened to create a new sustainable urban environment. Since the outer surfaces of building offer a great amount of space for vegetation, planting on roofs and walls has become one of the most innovative way to provide several envi…
Urban Stormwater Management, A Tool for Adapting to Climate Change: From Risk to Resource
2020
The effects of climate change on rainfall in the Mediterranean region are manifested in an overall decreasing trend, and greater irregularity in annual volumes and the city of Alicante is no exception. In addition, there has also been a spread of the urbanised area, which has led to an increase in the flood risk in urban areas (due to a greater runoff and the occupation of flood hazard areas) and drought events due to an increase in the water demand. In light of these new scenarios, the Mediterranean cities should design adaptation systems based on rainwater harvesting within the framework of a circular economy. This study analyses the integration of rainwater in flood and water demand mana…
IoT monitoring of urban tree ecosystem services: Possibilities and challenges
2020
Urban green infrastructure plays an increasingly significant role in sustainable urban development planning as it provides important regulating and cultural ecosystem services. Monitoring of such dynamic and complex systems requires technological solutions which provide easy data collection, processing, and utilization at affordable costs. To meet these challenges a pilot study was conducted using a network of wireless, low cost, and multiparameter monitoring devices, which operate using Internet of Things (IoT) technology, to provide real-time monitoring of regulatory ecosystem services in the form of meaningful indicators for both human health and environmental policies. The pilot study w…

Valore relazionale dello spazio pubblico dei servizi e welfare urbano
2023
Il portato ideale che aveva animato il dibattito e la ricerca in campo urbanistico sulla dotazione di attrezzature e servizi pubblici si era già infranto nel modo in cui, dalla fine degli anni ’60, era stato formulato e attuato il provvedimento sugli standard e oggi si infrange vieppiù in una realtà sociale profondamente modificata. In un contesto di frammentazione dei gruppi sociali che esprimono bisogni eterogeni e raramente rappresentati, tuttavia, il valore relazionale dello spazio pubblico dei servizi permane come uno dei capisaldi che fanno delle dotazioni pubbliche di servizi a scala urbana e di quartiere i centri di riferimento per le comunità insediate, prime fra tutti le scuole. D…
Barriers and Bridges for Landscape Stewardship and Knowledge Production to Sustain Functional Green Infrastructures
2018
Sustainable landscapes and regions require both stewardship and management to sustain the composition, structure and function of ecosystems as a base for delivering human benefits. This complex is captured by the topic of ecosystem services. To deliver these, the concept green (or blue) infrastructure emerged as a tool for spatial planning of networks of natural and semi-natural areas. Such planning requires evidence-based knowledge about both ecological and social systems. For ecosystems, states and trends need be monitored, and improved knowledge must be developed about ecological tipping points for assessment of sustainability, as well as measures for conservation, management and restora…
