Conceptualising State-Controlled Resort Islands for an Environment-Friendly Development of Tourism: The Maldivian Experience
2001
The Maldives host a sophisticated and competitive international tourist industry which has replaced fishing as the dominant economic activity. With their rich tropical reef ecosystems and the abundant biodiversity of their marine environment, a total of 86 uninhabited islands had been converted into Resort Islands by the end of 2000. Resort Islands are equipped with comprehensive facilities for accommodation, food, recreation and leisure. They are also strictly reserved for foreign tourists and guarantee complete privacy. This gives the benefit of averting conflicts of acculturation with local islanders. In the arena of impacts on the physical environment, however, the consumptive leisure l…
Introduction: Energy, Policy and the Environment: Modeling Sustainable Development for the North
2011
Climate change is unequivocal (IPCC 2007) and it has brought questions of energy and the environment to the forefront. It is unclear to what extent the traditional environmental concern and environmental policy suffice in addressing issues such as climate change while global greenhouse gases continue to increase at a steady rate, as does the depletion of fossil fuels. Ensuring the availability of energy is the key to maintaining current levels of well-being in societies and growth in the global economy. Given that production and utilization of energy and the environment are inherently interlinked, energy policies and changes in economic structures, which focus on alternative modes of energy…
The study programme “Environmental protection and impact assessment” at the University of Latvia
2001
Reviews trends in environmental protection and sustainability in Latvia and introduces a programme in this field at the University of Latvia in Riga. Concludes that regional changes are necessary.
PROPOSALS FOR ENVIRONMENTAL NOISE MANAGEMENT BOOST AT A NATIONAL LEVEL IN THE EUROPEAN UNION MEMBER STATES
2017
Environmental noise is currently becoming one of the most dominant types of environmental pollution. The effects of environmental noise closely correlate with quality of life especially regarding the physical and psychological health of inhabitants, social and economic costs, and thus also impacting the sustainable development of a country. Environmental noise management, therefore, is one of the most necessary and exigent aspects of environmental pollution management governance. The management of noise need to be developed in a comprehensive, integrative and cross-sectorial way, and appropriate methods and approaches for the management of overall noise impacts need to be found to deal with…
Network design for surface water quality monitoring in a road construction project using Gamma Test theory
2021
Road construction has a negative environmental impact on the surrounding aquatic environment, requiring the continuous monitoring of surface water quality. Here, optimization of the water quality monitoring network (WQMN) is an essential step in supporting the sustainable development of road construction projects. This study introduces Gamma Test theory (GTT) as a practical method for optimizing the WQMN of surface waters during road construction. The water quality index (WQI) was computed in 48 monitoring stations for six monitoring periods from 2017 to 2019; data was acquired from a primary monitoring network over a new highway in southern Norway. Based on the results, it is possible to r…
Metal–organic framework technologies for water remediation: towards a sustainable ecosystem
2018
Having access to clean water is a mandatory requirement for the proper development of living beings. So, addressing the removal of contaminants from aquatic systems should be a priority research topic in order to restore ecosystem balance and secure a more sustainable future. The fascinating structures and striking physical properties of metal–organic frameworks (MOFs) have revealed them as excellent platforms for the removal of harmful species from water. In this review, we have focused our attention on critically highlighting the latest developments achieved in the adsorptive removal of inorganic – metal cations, inorganic acids, oxyanions/cations, nuclear wastes and other inorganic anion…
The economies of the Baltic Sea Region in relation to green economics, with particular focus on Latvia: environmental sustainability and well-being
2010
Economic activity has an impact on the environment, but the potential degree of this impact will depend on several factors which are mainly determined by the technology used. This paper analyses the potential environmental impact the economies of the Baltic Sea Region have on their respective countries. The Baltic Sea Region countries are characterised by two economic development scenarios, namely, market and transition economies. Income levels, applied technologies and environmental management practices in these countries differ considerably, and affect a variety of complex indices. These are used to evaluate a country's overall environmental situation and the well being of its inhabitants…
Environmental modelling of aluminium based components manufacturing routes: Additive manufacturing versus machining versus forming
2018
Abstract Additive Manufacturing represents, by now, a viable alternative for metal-based components production. Therefore the designer, often, has to select among three options at process design stage: subtractive, mass conserving, and additive approaches. The selection of a given process, besides affecting the manufacturing step impact, influences significantly the impact related to the material production step. If the process enables a part weight reduction (as the Additive Manufacturing approaches do) even the use phase is affected by the manufacturing approach selection. The present research provides a comprehensive environmental manufacturing approaches comparison for components made o…
A methodology for the environmental comparison of metal shaping technologies: an in-depth analysis on recycling related issues
2015
The reduction of CO2 emissions is an urgent objective to pursue. The scientific and the industrial world have gathered such challenge, starting to find out energy- and resource-efficient manufacturing strategies. From the literature review, in the domain of environmental impact analysis of manufacturing processes, two relevant knowledge gaps can be spotted: (1) the metal forming processes (and, in particular, the bulk forming processes) are still not well documented, and (2) there is a lack of systematic and comparative studies on energy and material flows enabling the identification of environmentally-friendly manufacturing design strategies. This research offers a contribution to a better…
Data from: Ecological impact assessments of alien species in Norway
2020
Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in local biodiversity and ecosystem functioning, and, ultimately, to biotic homogenisation. We risk-assessed all alien plants, animals, fungi and algae, within certain delimitations, that are known to reproduce in Norway. Mainland Norway and the Arctic archipelago of Svalbard plus Jan Mayen were treated as separate assessment areas. Assessments followed the Generic Ecological Impact Assessment of Alien Species (GEIAA) protocol, which uses a fully quantitative set of criteria. A tot…
