Optimal growth and land preservation
1997
A model of optimal economic growth with a constant population subject to a constraint on the availability of land is presented. It takes account of the dual character of land as a production factor and as a consumption good (environmental amenities) by determining the optimal intertemporal allocation of land between productive and recreational uses. An extension of the analysis for the case of a growing population with endogenous growth based on human capital accumulation shows that if the rate of discount is not very low then there exists a set of balanced growth paths compatible with a constant allocation of land. En este trabajo se presenta un modelo de crecimiento económico óptimo con u…
Risk, Terrorism, and Tourism Consumption
2017
The present chapter discusses to what extent the rise of new risks and dangers, modernity has brought, has causing the end of tourism. The answer to the above formulated questions is not easy, and of course, it exhibits a fertile ground to be explored in other approaches. The ceaseless news about violence, cruelty, wars and deaths have serious negative impacts on audience worldwide. Though policy makers have devoted their time and efforts in looking for new alternative segments where death replaces the allegory of beautiness, giving as a result new products as dark-tourism, slum-tourism, disaster-tourism or doom-tourism, other problems arise. The curiosity for tourists in visiting spaces of…
The Southern African Power Pool: An Electrifying Project with Untapped Potential
2017
This chapter turns to infrastructure and gives an outstanding analysis of regional electricity cooperation in the SADC within the framework of the Southern African Power Pool (SAPP). The author illustrates the regional power imbalances in terms of national electricity generation and consumption which fuel the SADC countries’ demand for a regional electricity market and an interconnected regional power grid. It becomes clear that the SAPP’s institutional design is strongly influenced by South Africa as the hub of the existing power network and largest electricity producer. Influence by external actors is supportive of regional electricity cooperation since the EU provides funding for the SAP…
Household Expenditure on Leisure: a Comparative Study of Italian Households with Children from Y- and Z-Generation
2019
The intrinsic complexity of post-materialist society makes it challenging to investigate the connection between social changes and generations. However, the study of consumption might help in the analysis of such a connection. In this paper, we analyse empirical data of consumption on leisure of Italian households, and focus on families at a very precise stage of family life-cycle, that is, couples with teenager children. We look at consumption of households at different points in time, 2001, 2007, and 2012, in order to investigate the impact of both social change and generation of children–Y-generation in 2001 and 2007, and Z-generation in 2012–on the leisure expenditure patterns of famili…
Domestic demand predictions considering influence of external environmental parameters
2015
A precise prediction of domestic demand is very important for establishing home energy management system and preventing the damage caused by overloading. In this work, active and reactive power consumption prediction model based on historical power usage data and external environment parameter data (temperature and solar radiation) is presented for a typical Southern Norwegian house. In the presented model, a neural network is adopted as a main prediction technique and historical domestic load data of around 2 years are utilized for training and testing purpose. Temperature and global irradiation (which illustrates the solar radiation level quantitatively) are employed as external parameter…
Novel Energy Modelling and Forecasting Tools for Smart Energy Networks
2015
A novel Energy Modelling and Forecasting Tool (EMFT) has been adopted for use in the VIM SEN (Virtual Microgrids for Smart Energy Networks) project and this paper gives an insight of the techniques used to provide vital support to the energy market, in particular to energy aggregators. A brief description of one of the test sites where data has been collected for validation of the EMFT will be outlined and some examples shown. The information and predictions will then be used by a decision support system to dynamically adjust energy delivery and consumption, by giving advice to users and operators on actions they can take to obtain a better match between energy supply and demand that increa…
Smart energy users: ICT instruments for the consumer awareness
2015
The European Commission is supporting many projects in the field of energy saving, with the aim to improve user behavior and to help Europe to meet emission targets. In October 2012, the European Union adopted the Energy Efficiency Directive with the aim to reduce the primary energy consumption by 20% by 2020. One key point in the reduction of energy consumption energy is the awareness of final users about their usage of energy. At the same time, policies aimed at improving the efficiency of energy use, are a keystone in the strategies of leading Distribution System Operators (DSOs) and energy retail companies that started to offer, in addition to the energy supply, services and suggestions…
New trends in technology and identity of traditional dairy and fermented meat production processes: Preservation of typicality and hygiene
2014
Interest in ecofood tourism is strictly related to the consumption of products associated with the geographical area visited. Local products are often requested by consumers living far from the production zones (e.g. in bistro restaurants that reproduce the atmosphere of typicality). This phenomenon, if on the one hand guaranteeing the continued popularity of certain traditional foods, highlights the inherent dangers that certain types of food pose. They could spread the risks to a much wider area that they might typically inhabit. The higher the demand for certain products, the more variations of the production processes of the traditional products there will be. This is particularly evide…
EU Experts’ Attitude Towards Use of GMO in Food and Feed and Other Industries
2014
Abstract This article examines European Union (EU) experts’ attitude towards use of genetically modified organisms (GMO) in food, feed and other industries with an eye to developing a general model of EU experts’ opinion formation in this area. The gene engineering has seen rapid advances in recent years with a host of new applications in medicine, agriculture, and related fields. Taking into account the history of consumption, social, economic, cultural and other aspects and the risk perception in general regarding these products the consumers’ willingness to buy genetically modified (GM) products varies from country to country as well as attitude of the experts involved in the decision ma…
Photovoltaic electricity scenario analysis in urban contests: an Italian case study
2012
Abstract This paper shows a methodology for the assessment of the photovoltaic potential in urban areas using Google Earth™ tool that provides either satellite images of the roofs of buildings or their number of floors by means of the Street View function. The applicability of the methodology has been tested on a selected urban area of the city of Palermo in the South of Italy. After classifying roofs according to the shape, orientation and pitch of buildings with different morphologies, the share of energy generated by the installable PV systems was evaluated with regard to the number of floors. Moreover the coverage of the electricity demand was investigated on the basis of the consumptio…
