    Review of Life Cycle Assessment in Agro-Chemical Processes

    Life Cycle Assessment (LCA) is a method used to evaluate the potential impacts on the environment of a product, process, or activity throughout its life cycle. Today’s LCA users are a mixture of individuals with skills in different disciplines who want to evaluate their products, processes, or activities in a life cycle context. This study attempts to present some of the LCA studies on agro-chemical processes, recent advances in LCA and their application on food products and non-food products. Due to the recent development of LCA methodologies and dissemination programs by international and local bodies, use of LCA is rapidly increasing in agricultural and industrial products. The literatures suggest that LCA coupled with other environmental approaches provides much more reliable and comprehensive information to environmentally conscious policy makers, producers, and consumers in selecting sustainable products and production processes. For this purpose, a field study of LCA of biodiesel from Jatropha curcas has been taken as an example in the study. In the past, LCA has been applied primarily to products but recent literature suggests that it has also the potential as an analysis and design tool for processes and services. In general, all primary industries use energy and water resources and emit pollutants gases. LCA is a method to report on and analyze these resource issues across the life cycle of agro-chemical processes. This review has the importance as a first part of a research project to develop a life cycle assessment methodology for agro-chemical industries. It presents the findings of a literature review that focuses on LCA of agriculture and chemical engineering literatur

    frameworks and methods for impact assessment

    This study provides an overview of existing approaches and methods for assessing the environmental impacts of trade and trade-related activities. It considers both approaches that are tailored to the assessment of trade- environment linkages and more generic approaches for environmental assessment and analyzes their respective usability in the context of trade-related development cooperation. The study thereby aims to contribute to a more extensive use of such tools, while improving the practice and application of environmental assessments of trade-related policies and programs. In doing so, the study will complement the existing study on the assessment of the socio- economic impacts from trade carried out by the Overseas Development Institute (ODI)1. The study is divided into two parts. Part I begins with a brief discussion on trade-related development cooperation followed by a short overview of the debate on trade, development and the environment. Next it provides an overview of existing approaches to conceptualizing environmental impacts from trade-related activities. After this, it provides a general introduction to impact assessment (IA) and the assessment of environmental impacts in this context. It closes with a brief overview of the assessment of environmental aspects in German development cooperation. Part II provides a more detailed review of existing frameworks and methods for assessing the environmental impacts from trade-related policies and programs

    An empirical investigation of wood product information valued by young consumers

    Get PDF
    Recent media reports regarding wood products question the trustworthiness of wood origin declaration, the sustainability of production methods and the product quality. In light of this question, it becomes important to ensure consumer trust in wood and wood-based products. Current research indicates that providing product information enhances product trust and purchase intentions, while young consumers in particular seek detailed product information. However, it is necessary to determine which wood product information young consumers strongly value because providing a high amount leads to information overload. As information needs may vary between different consumer segments, the present work aims at identifying segments of young consumers and their preferred wood-product information. The importance of different wood product information items concerning the purchase decision was investigated with a German-language online survey (N = 185, age range 18–30). A cluster analysis revealed four consumer segments. Thereof, three segments (an environmentally oriented, an environmentally and quality oriented, and a quality oriented segment) valued the provision of wood product information. The preferred information types differed among the three segments. Overall, this paper provides insights into young consumers' preferences for wood product information and the consumer segments on which marketing should focus

    Training of Crisis Mappers and Map Production from Multi-sensor Data: Vernazza Case Study (Cinque Terre National Park, Italy)

    Get PDF
    This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

    Human Dimensions of the Ecosystem Approach to Fisheries: An Overview of Context, Concepts, Tools and Methods

    Get PDF
    This document aims to provide a better understanding of the role of the economic, institutional and sociocultural components within the ecosystem approach to fisheries (EAF) process and to examine some potential methods and approaches that may facilitate the adoption of EAF management. It explores both the human context for the ecosystem approach to fisheries and the human dimensions involved in implementing the EAF. For the former, the report provides background material essential to understand prior to embarking on EAF initiatives, including an understanding of key concepts and issues, of the valuation of aquatic ecosystems socially, culturally and economically, and of the many policy, legal, institutional, social and economic considerations relevant to the EAF. With respect to facilitating EAF implementation, the report deals with a series of specific aspects: (1) determining the boundaries, scale and scope of the EAF; (2) assessing the various benefits and costs involved, seen from social, economic, ecological and management perspectives; (3) utilizing appropriate decision-making tools in EAF; (4) creating and/or adopting internal incentives and institutional arrangements to promote, facilitate and fund the adoption of EAF management; and (5) finding suitable external (non-fisheries) approaches for financing EAF implementation
