Competitiveness and sustainability in horticulture: strategy for small businesses

2018

Vegetable cultivation has a significant history in the countries of the Mediterranean basin. Italy is an important horticultural producer and, in this context, Sicily offers ideal conditions for the protected cultivation of field vegetables. Apart from a few well-organised producers, in many areas horticulture is characterised by backward entrepreneurial systems and fragmented production lines that make the vegetable market one that is very close to being a rigged competition in which companies must accept the price and have no negotiating power. This situation has been aggravated even further by the recent economic crisis and the subsequent recession, resulting in the disappearance of the …

Modeling the influence of alternative forest management scenarios on wood production and carbon storage: A case study in the Mediterranean region

2016

Forest ecosystems are fundamental for the terrestrial biosphere as they deliver multiple essential ecosystem services (ES). In environmental management, understanding ES distribution and interactions and assessing the economic value of forest ES represent future challenges. In this study, we developed a spatially explicit method based on a multi-scale approach (MiMoSe-Multiscale Mapping of ecosystem services) to assess the current and future potential of a given forest area to provide ES. To do this we modified and improved the InVEST model in order to adapt input data and simulations to the context of Mediterranean forest ecosystems. Specifically, we integrated a GIS-based model, scenario …

Ethics, resource rent, environment and petroleum policy: the case of a small open economy

2021

This paper contributes to the understanding of how the environment, ethics, values, and historical contingencies shape public policy. It explains the accomplishment of petroleum resource management in the small open economy of Norway. The study is conducted by mapping policy decisions and the arguments behind them regarding environmental and ethical issues. This is done by studying available governmental and parliamentary papers along with statements from politicians and central governmental officials. The paper also seeks to illuminate some of the decisions by quantitative measures. The paper firstly describes a model of Ricardian resource rent. Secondly, it investigates the set of values …

The impact of privatization approaches on the productivity growth of the water industry: A case study of Chile

2015

Abstract The water industry faces the challenge of implementing privatization reforms. This process mainly adopts the following two approaches: the privatization of public water and sewerage services (WSS) and the privatization of water companies’ ownership. This paper investigates the impact of both privatization approaches on changes in productivity in the water industry. In doing so, the Luenberger productivity indicator (LPI) was computed for a sample of Chilean water and sewerage companies (WaSCs) for the period 1997–2013. Unlike the most commonly applied index (Malmquist productivity index), the LPI simultaneously takes into account output expansion and input contraction. The results …

Methodological approaches to the valuation of forest ecosystem services: An overview of recent international research trends

2021

Forests represent the most important source of ecosystem services (ES) on a global level both for the production of goods and for the provision of services and externalities, nevertheless scientific research in the economic field is lacking. Currently the number of documents relating to ES is 16 673, of which only 1 379 concern the forestry sector. The aim of this study is to provide an overview of scientific research trends in the field of economic evaluation of forest ecosystem services (FES). To this end, an on-line bibliographic survey was carried out on the main scientific search engines, which made it possible to quantify the works and at the same time to detect the main evaluation me…

An Urbanistic Project Based on General Systems Theory

1991

This paper intends to be an outline of the Urbanistic Development Planning of the Valencian Community in Spain to be performed during the years 1991 to 1993, The following are considered as objectives of the Planning: – Quality of Life improvement, – protection of Nature, – rational management of natural resources, – rational use of land; all based on social demand. The territory and the mechanism of intervention is considered as a system whose elements can be grouped as: – uses of land, – infrastructure, equipment, services, – objectives, – intervention and management. The Planning proposes itself to be: integral, strategic, prospective, programmed, controllable and participative, A simula…

Wine - investment: a profitable alternative investment or a simple long term pleasure?

2014

International audience; The purpose of this work is twofold: - to make a first historic analysis of performance through an investment in wine by comparing its performance with those that would have been possible to obtain at the same time by providing financial term investments; - to introduce the regional diversity of performance by considering the situation in the three selected geographic areas.

Is there a Market Value for Energy Performance in a Local Private Housing Market ? An efficiency analysis approach

2018

This paper aims to find evidence of a “green value” in a local housing market using notarial data on a small urban area in France. We use frontier functions, an original approach that departs from customary hedonistic regressions, to model housing market prices as a production set bordered by an efficiency frontier estimated by Data Envelopment Analysis (DEA). The paper tests if difference in prices (i.e. the distance from the frontier) can be explained by energy performance measured as a normalized categorical ascending kWh/m²/year grade (or Energy Performance Certificate -EPC). We show that there is significative evidence for energy performance's market value. The “Green Property Value” i…
