Special Issue: Enhancing Sustainable Performance in Organizational and Inter-Institutional Systems
2013
Sustainability is not just for Christmas… it’s for life. Sustainable solutions, whether sought in terms of business strategies, social policies, or the exploitation of natural resources have to serve organizations and communities in the long term, sometimes very long term, as well as the short term. Static analysis is unlikely to be able to evaluate candidate solutions fully, and is more likely to focus on the short-term future to the detriment of the longer-term. Sustainable solutions are more likely to be developed from studies based on deep analysis using systems approaches, and from system dynamics (SD) approaches in particular.
Innovative Changes for Reaching Sustainability in Universities
2013
Abstract This paper presents an original approach to the changes required for the transformation of universities in sustainable universities. The focus is on the innovative approach of all activities and relationships of the university: teaching, scientific research and other services offered by the university, the relations of the university with the communities where it operates, inter-university relations, relations with business environment, etc. Based on the experience and information gathered by the authors in the strategic project “Improving University Management”, it is proposed a better, more efficient and more effective way of using the resources of universities, thus sharing the …
Monitoring of persistent organic pollutants in the polar regions: knowledge gaps & gluts through evidence mapping
2017
Persistent organic pollutants (POPs) are widespread compounds that accumulating in polar regions canalise through trophic webs. Although several dozens of studies have been carried out in the last decades, the information is generally scattered across a large number of literature sources. This does not allow an efficient synthesis and constraints our understanding on how address future monitoring plans and environmental conservation strategies on the Polar Regions with respect to POPs. Thus, here, we present the outcome of a systematic map (SM) to scope, screen and chart evidences from literature dealing with POPs in Polar regions. The SMs strive to produce rigorous guidelines and have rece…
Towards a more sustainable food Supply chain: opening up invisible waste in food service
2016
Future challenges to the global food supply chain are complex. In order to embrace sustainability, companies should change their management practices towards more efficient resource use. Food waste being a misuse of resources, we identify its causes and possible ways of minimising it. To achieve this goal, we conducted explorative research with qualitative and quantitative data through in-depth semi-structured interviews and an open questionnaire with top Spanish food service companies. Results show that most businesses mainly tend to minimise food waste according to economic criteria, without taking into account the social, ethical or environmental factors. As a consequence, just “visible”…
Special issue on Trends and challenges of sustainable irrigated agriculture
2014
In the twenty-first century, the shortage of freshwater is one of the most important environmental concerns facing several regions of the world because of the growing demand of increasing population, agricultural intensification, and economic growth. Global climate change will contribute to exacerbate the problem, generating new drought-prone areas and increasing those already characterized by severe aridity. Worldwide it is estimated that, on average, agriculture accounts for 70% of the total water consumption, compared with 10% for domestic consume and the remaining used by industry. Moreover, according to FAO estimates, by 2050 agricultural production has to increase by 60% to satisfy th…
Correlates and Predictors of L2 Willingness to Communicate in Polish Adolescents
2014
The concept of willingness to communicate (WTC) in L2 denotes “a readiness to enter into discourse at a particular time with a specific person or persons, using a L2” (MacIntyre et al. 1998, p. 547). In the early model of L2 WTC, there are two main variables influencing its levels: perceived communication competence and communication anxiety (MacIntyre 1994). WTC is now considered a fundamental goal of second language education (MacIntyre et al. 2003) because it offers L2 learners “greater chances for L2 practice and authentic L2 usage” (MacIntyre et al. 2001, p. 382). Students taking the risk of initiating communication in a language they do not know well are likely to become more proficie…
The volume and composition of dead wood on traditional and forest fuel harvested clear-cuts
2010
Logging residue and cut stumps are increasingly used as a renewable energy source known as forest fuel. Forest fuel harvesting obviously reduces the volume of dead wood and is likely to alter the dead wood composition, but the magnitude of the change is not known. Such information is important for the evaluation of the effects of forest fuel harvesting on biodiversity because a large proportion of forest dwelling species are directly dependent on dead wood. We measured the volume and characteristics of all dead wood units with a minimum diameter of 2 cm and a minimum length of 20 cm on 10 forest-fuel harvested and 10 traditional (control) clear-cuts. The total volume of dead wood at forest …
The implications of stand composition, age and spatial patterns of forest regions with different ownership type for management optimisation in northe…
2015
Abstract Forests with different ownership type often form complex mosaics of stands, thus adding new challenges to the spatial planning of sustainable management in forested landscapes. This study attempted to analyse the spatial patterns and age structures of forest regions with different ownership type and to formulate suggestions for the optimisation of tactical planning of forest management planning by addressing ecological functionality at the landscape level. We hypothesised that structure of forests of various ownership groups differs significantly. National forest inventory data from 2011 was used in this study to compare spatial patterns of forest stands and clearcuts, as well as f…
Forest types for biodiversity assessment at regional level: the case study of Sicily (Italy)
2007
Within Europe the question of plant coenosis is attracting growing interest. The quality and quantity of collected information on forest resources at a global level largely depends on the capacity to collect and analyse data at national and sub-national scale in a way compatible with those at global or continental levels. In Italy the acceptance of all the international agreements and protocols on the protection of the environment and management of natural resources, requires a standardization of collected information and statistics, with the aim to produce homogeneous and integrative data at global level. This need is reflected in the following points: (1) the adoption of a classification …
Using SMAA-2 method with dependent uncertainties for strategic forest planning
2006
Abstract Uncertainty included in forest variables is normally ignored in forest management planning. When the uncertainty is accounted for, it is typically assumed to be independently distributed for the criteria measurements of different alternatives. In forest management planning, the factors introducing the uncertainty can be classified into three main sources: the errors in the basic forestry data, the uncertainty of the (relative) future prices of timber, and the uncertainty in predicting the forest development. Due to the nature of these error sources, most of the involved uncertainties can be assumed to be positively correlated across the alternative management plans and/or criteria.…
