Metabolism and environmental impacts of household consumption: : A review on the assessment, methodology, and drivers

Abstract: The focus when analyzing the environmental requirements and impacts of the economic system is usually placed on production activities. But all production is associated with final consumption, and recently many studies have also been dedicated to final consumption. This article comprehensively reviews the biophysical assessment of households from the point of view of materials and energy required and emissions and wastes resulting from household consumption patterns. Although the aggregation bias and methodological variability make comparisons difficult, some patterns can be recognized. Results show that for many Organization for Economic Cooperation and Development (OECD) and a few developing countries, household metabolism has been mainly assessed from the energetic perspective, stressing household responsibility for emissions of greenhouse effect gases and climate change. Few studies deal with other emissions and wastes. There is a lack of information about material requirements, too. Environmental input-output (I-O) analysis and life cycle assessment are the methods usually employed, together with the use of economic, environmental, and expenditure information. Information about direct inputs and outputs is complemented with data on the environmental requirements associated with the consumption of goods and services. Multiregional I-O techniques have been used to capture upstream requirements in an attempt to avoid errors owing to truncation and domestic technology assumptions. Housing, food, and mobility are the most important consumption categories, but the shares of these categories in the requirements are different according to environmental, socioeconomic, and demographic factors. Finally, challenges for further research are discussed based on the need for new methodological developments, as well as the potential of the metabolic narrative to elaborate information relevant to sustainable consumption policies

Twenty years of ecosystem services: How far have we come and how far do we still need to go?

Abstract: It has been 20 years since two seminal publications about ecosystem services came out: an edited book by Gretchen Daily and an article in Nature by a group of ecologists and economists on the value of the world’s ecosystem services. Both of these have been very highly cited and kicked off an explosion of research, policy, and applications of the idea, including the establishment of this journal. This article traces the history leading up to these publications and the subsequent debates, research, institutions, policies, on-the-ground actions, and controversies they triggered. It also explores what we have learned during this period about the key issues: from definitions to classification to valuation, from integrated modelling to public participation and communication, and the evolution of institutions and governance innovation. Finally, it provides recommendations for the future. In particular, it points to the weakness of the mainstream economic approaches to valuation, growth, and development. It concludes that the substantial contributions of ecosystem services to the sustainable wellbeing of humans and the rest of nature should be at the core of the fundamental change needed in economic theory and practice if we are to achieve a societal transformation to a sustainable and desirable future.

Input Output Analysis Foundations And Extensions

Abstract: Thank you very much for reading input output analysis foundations and extensions. As you may know, people have search hundreds times for their chosen readings like this input output analysis foundations and extensions, but end up in infectious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they are facing with some malicious virus inside their desktop computer.

Defining the Anthropocene

Abstract: Time is divided by geologists according to marked shifts in Earth's state. Recent global environmental changes suggest that Earth may have entered a new human-dominated geological epoch, the Anthropocene. Here we review the historical genesis of the idea and assess anthropogenic signatures in the geological record against the formal requirements for the recognition of a new epoch. The evidence suggests that of the various proposed dates two do appear to conform to the criteria to mark the beginning of the Anthropocene: 1610 and 1964. The formal establishment of an Anthropocene Epoch would mark a fundamental change in the relationship between humans and the Earth system.
