Benefits of Urban Green Space for Improving Urban Climate
2007
Urban settlements transform the natural environment so greatly that people tend to see the city only as an employment site, and economic and cultural center. Thus a growing number of people prefer to reside in greener suburbs or rural areas. This results in increased automobile commuter traffic, accompanied by traffic jams, accidents, stress, and ever more damage to the environment. Concepts of sustainable development or the ecological city represent strategies for changing these negative trends. The purpose for doing so is principally the well-being of a city’s residents. Often this entails bringing more of the natural environment back into the city, because urban green space fulfills seve…
Impacts of urban environment on the eco-physiological responses of trees: Tree-Talker (TT) new devices for the monitoring of trees
2019
Urban ecosystems will become increasingly important in the coming years. Urban trees are likely to increase in importance to society as their value in enhancing people's sense of well-being as well as the direct economic impacts are increasingly recognized. Urban forest monitoring data are essential to assess the impacts of tree planting campaigns and management programs. Tree-Talker (TT) is a device based ton the Internet of Things (IoT) technology for the monitoring of trees physical and physiological conditions. The TT allows the monitoring of (i) multispectral measurements of the sunlight transmitted through the canopy in 12 bands across the visible and near infra-red spectra; (ii) sap …
Pianificazione forestale territoriale ai fini della mitigazione del dissesto idrogeologico nel bacino del Fiume Imera Settentrionale (PA)
2013
I fenomeni di dissesto idrogeologico determinato dall’azione dei fattori naturali su superfici di diversa natura modificano profondamente il paesaggio. Alle cause di origine naturale si aggiungono le pressioni di natura antropica con effetti negativi nei riguardi del suolo aumentandone la suscettibilità al dissesto. L’obiettivo del presente lavoro è analizzare i dissesti in atto all’interno del bacino del Fiume Imera Settentrionale allo scopo di verificare la possibilità di mitigare tali fenomeni mediante l’adozione di una adeguata pianificazione di interventi forestali. L’indagine ha permesso di analizzare in ambiente GIS la distribuzione dei dissesti cartografati nell’ambito del Piano di …
Hydroponic Lettuce Cultivation Using Organic Nutrient Solution from Aerobic Digested Aquacultural Sludge
2021
The aim of this study was to demonstrate how aquacultural sludge can be processed and utilized as an organic nutrient solution (ONS) for hydroponic lettuce production. By using a previous developed method, approximately 80% of the processed sludge was reclaimed as a clear, nutrient-rich solution. The performance of the recovered nutrient solution on lettuce growth was assessed in a nutrient film hydroponic system. The results were compared to the results obtained using a conventional nutrient solution (CNS). Yield, fresh weight, water consumption, and nutrient and heavy metal content in leaf tissue were measured. In spite of a 16% lower average fresh weight obtained in ONS compared to the w…
Planning to meet challenges in shrinking rural regions. Towards innovative approaches to local planning
2023
In this article we ask to what extent is current demographic development reflected in the present planning and policy practice of shrinking municipalities; whether there is a focus on strategies and measures for population growth; and, finally, to what extent do politicians and planners think we should change the way we plan based on the expected demographic changes. Our study illustrates how challenging it is for shrinking municipalities to break with established practices and modes of policy development and to adopt a more sustainable position. The ‘stigma’ of shrinking (Sousa & Pinho 2015) is at odds with the ideals of the local politicians. However, we find that the response in planning…
Regional climate model simulations for Europe at 6 and 0.2 k BP: sensitivity to changes in anthropogenic deforestation
2014
International audience; This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, ∼ 6 and ∼ 0.2 k BP in Eu-rope. We apply the Rossby Centre regional climate model RCA3, a regional climate model with 50 km spatial resolution, for both time periods, considering three alternative descriptions of the past vegetation: (i) potential natural vegetation (V) simulated by the dynamic vegetation model LPJ-GUESS, (ii) potential vegetation with anthro-pogenic land use (deforestation) from the HYDE3.1 (History Database of the Global Environment) scenario (V + H3.1), and (iii) potential vegetation with anthropogenic land …
Participation and compensation claims in voluntary forest conservation: A case of privately owned forests in Finland
2009
Abstract A new market-based voluntary programme aimed at preserving forest habitats on private land has been implemented in Finland. This scheme is based on conservation by fixed-term agreements between forest owners and a governmental authority. In this study we examine the characteristics of forest owners and their properties that indicate the owners' willingness to participate in the programme. In addition, we analyse factors affecting the real compensation claims. The study uses a dual set of data from the pilot project, i.e. one data set supplied by the authority and another collected from the owners involved in the project. The results suggest that to increase the participation rate, …
Agritourism and local development: A methodology for assessing the role of public contributions in the creation of competitive advantage
2018
Abstract Agriculture has been an economic mainstay of countries throughout history. Recently, its importance and essential role in local and regional growth and development have also received due acknowledgment. However, agritourism entrepreneurs often lack the necessary means, when relying only on their own funds alone. For these reasons, targeted aid measures are provided at the regional, national and European levels, provided they fulfill specified subjective and objective eligibility criteria. This investigation aims at understanding the rationale, if any, according to which the Public Administration allots such contributions. To this end, a two-tiered analysis was conducted on the data…
