AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

AbstractE-waste is a new term coined in the market of hazardous substances. It has taken a new bourgeoning route since the boom of Information Technology (IT). The problems regarding the transportation, handling and dispose have to be tackled at the earliest as it might cause detrimental effects on environment. Presently in India there is no distinct and lucid regulation(s) regarding e-waste management. There should one stop solution! In the present paper, some of the Technical and E-Management ...

AbstractThe mechanisms in the shaping of organic food in Denmark since the 1970'ies are analysed as a contribution to the discussion of strategies for a more sustainable production and consumption of food. The background is the major  achievements in Denmark within organic food since the 1970'ies, but also the recent years' reduction in the land converted to organic farming. The analyses are based on experiences from projects, analyses and literature and draw on innovation theory and theory...

AbstractDue to rapid growth in both population and economic development in China, water demand is increasing dramatically andChina is facing more and more severe water scarcity problems. Thus competitions for water (between uses, users and regions) areincreasing which make water use efficiency an important issue in China, together with the uneven spatial and temporaldistribution of water, all of which drive the Chinese government and water planners to find the optimal water resource allocationpl...

However, few attempts have been made to investigate precise relationship between carbonfootprint and influential factors. In this paper, STIRPAT model was employed to reveal the dynamic relationships betweencarbon fo...

A quick and efficient response to an emergency incident is critical to avoiding further damage, so its evaluation is important before taking real action. In this study, a framework for response strategy evaluation is proposed based on a whole-process risk analysis of historical accidents, which provides a method to compare the efficiency of different response strategies in a hypothetical scenario. The framework is a multi-step procedure consisting of three major steps: system definition, inde...

The economic literature provides ample evidence that tourism makes intensive use of land both as a product and as a production factor. However, what is now known as mass tourism was developed in a setting in which respect for the environment among businesses and consumers was conspicuous by its absence. This situation has recently changed as consumers increasingly demand sustainable tourism products and require companies to respect specific environmental commitments. How companies manage thi...

Since the link between tourism and economic growth is not automatic, a country must meet certain characteristics in order for this link to occur and make it sustainable through time. Among these characteristics, environmental and sustainable policies, the existence of hard and soft infrastructure, a regulated labour market and economic and financial indicators play a key role. Therefore, Country Risk Score (CRS) can represent a good indicator of the sustainability of countries. Using Country ...

The polyhydroxybutyrate (PHB) production by photoautotrophic cultures is a potential eco-sustainable process to produce bioplastics. The biosynthesis of PHB by cyanobacteria meets a twofold target: the use of CO2 as feedstock alternative to the fossil resource used in the conventional processes; the contribution to the reduction of the CO2 concentration in the atmosphere. This contribution reports results of a study regarding the optimal growth conditions for cyanobacteria to produce PHB unde...
