The efficiency of LiDAR HMLS scanning in monitoring forest structure parameters: implications for sustainable forest management

2022

PurposeThis article aims to compare the LiDAR handheld mobile laser scanner (HMLS) scans with traditional survey methods, as the tree gauge and the hypsometer, to study the efficiency of the new technology in relation to the accuracy of structural forest attributes estimation useful to support a sustainable forest management.Design/methodology/approachA case study was carried out in a high forest located in Tuscany (Italy), by considering 5 forest types, in 20 different survey plots. A comparative analysis between two survey methods will be shown in order to verify the potential limits and the viability of the LiDAR HMLS in the forest field.FindingsThis research demonstrates that LiDAR HMLS…

Designing a sustainable regeneration in the outskirt of Agrigento

2016

This paper describes a case of building recovery and sustainable re-use in Sicily, that is the recovery of Villaseta. It is a very degraded neighborhood in the outskirts of Agrigento. The main goal of the redevelopment project is therefore the rebuilding and the environmental regeneration of the neighborhood, using sustainable technologies and tools, with the construction of vegetable gardens and urban gardens, the production of renewable energy and the sustainable recovery of existing buildings. The eco-friendliness of the restoration project is therefore given by the use of garden roofs and vertical gardens. Villaseta will be a real "green lung" able to give greater environmental awarenes…

Sustainable Development and Technological Impact on CO2 Reducing Conditions in Romania

2015

Climate change is a reality all over the world, and its complexity is increasing. Therefore, sustainability has become a national and international concern, ingrained in many organizational processes. The ability of organizations to respond to sustainability concerns is sometimes hindered by the complexity of integrating sustainability into business models and by the need to rethink their strategic directions. In Romania, sustainable development has become a priority for businesses, but even though companies are showing some concern, there are yet to demonstrate any full commitment (they are mainly concerned with areas such as society and the environment). This paper assesses Romania’s invo…

Car sharing demand estimation and urban transport demand modelling using stated preference techniques

2008

The research deals with the use of the stated preference technique (SP) and transport demand modelling to analyse travel mode choice behaviour for commuting urban trips in Palermo, Italy. The principal aim of the study was the calibration of a demand model to forecast the modal split of the urban transport demand, allowing for the possibility of using innovative transport systems like car sharing and car pooling. In order to estimate the demand model parameters, a specific survey was carried out inside the urban area of Palermo. The survey focused on the morning rush hour and involved mainly employees, self-employed workers and students (about 500 respondents) whose final destination was lo…

Valorisation of industrial iron oxide waste to produce magnetic barium hexaferrite

2016

Barium M-type hexagonal ferrite (BaM, BaFe12O19) is an immensely important magnetic material, which we have successfully made from the simple valorisation of Fe-rich industrial waste from steel wire drawing, with addition of BaCO3 and heating in air to 1000 degrees C. The optimum ratio of Fe. Ba (producing 86 wt% BaM) was found to be 11: 1 (non-stoichiometric), and secondary phases of alpha-Fe2O3 (non-magnetic) and ZnFe2O4 (poorly antiferromagnetic) were always present. This material consisted of small submicron platelets. A hard magnetic ferrite was produced with Ms=48.6 A m(2) kg(-1) and H-c=211.5 kA m(-1). The highest density was achieved by sintering samples with Fe: Ba ratios of 11: 1 …

Sustainable Development and Energy Policy: Actual CO2 Emissions in the European Union in the Years 1997–2017, Considering Trade with China and the USA

2020

One of the ways of implementing the concept of sustainable development by the European Union is their energy policy. Among the three main objectives in its energy policy is a reduction in greenhouse gases (mainly CO2) emissions to at least 20% below 1990 levels by 2020. This study aims to assess the impact of international trade on actual CO2 emission in the EU, China and the USA for the period 1997–2017. For this aim, the Actual-Open CO2 emissions were calculated, taking into account the transfer of CO2 in exported products and services from China and the USA to the EU and vice versa. It is concluded that the actual CO2 emissions in China, the USA, and the EU differed from the traditionall…

URBAN RESILIENCE AND WASTE MANAGEMENT: PROPOSALS OF NEW INFRASTRUCTURES FOR URBAN AREAS AND BUILDINGS

2015

La produzione ingente di rifiuti, quale conseguenza di costumi di vita volti allo spreco, rende vulnerabili i sistemi urbani che possono essere sottoposti, in casi emergenziali, a pressioni eccezionali e incontrollate con situazioni prossime al collasso. Un’opportuna e corretta gestione integrata dei rifiuti contribuisce alla resilienza dei sistemi urbani. Perciò si rendono necessarie la pianificazione e la progettazione di nuovi servizi e l’individuazione/integrazione di spazi e dotazioni tecnologiche per incentivare la popolazione a effettuare la raccolta differenziata in modo corretto e costante. Si presentano gli esiti di uno studio svolto in un piccolo centro siciliano. Partendo dalle …

The Economic Impact of Restricted Water Supply: a Computable General Equilibrium Analysis

2007

Water problems are typically studied at the level of the river catchment. About 70% of all water is used for agriculture, and agricultural products are traded internationally. A full understanding of water use is impossible without understanding the international market for food and related products, such as textiles. The water embedded in commodities is called virtual water. Based on a general equilibrium model, we offer a method for investigating the role of water resources and water scarcity in the context of international trade. We run five alternative scenarios, analyzing the effects of water scarcity due to reduced availability of groundwater. This can be a consequence of physical con…
