Resource Prices
Resource intensity is a measure of the resources (e.g. water, energy, materials) needed for the production, processing and disposal of a unit of good or service, or for the completion of a process or activity; it is therefore a measure of the efficiency of resource use. It is often expressed as the quantity of resource embodied in unit cost e.g. litres of water per $1 spent on product. In national economic and sustainability accounting it can be calculated as units of resource expended per unit of GDP. When applied to a single person it is expressed as the resource use of that person per unit of consumption. Relatively high resource intensities indicate a high price or environmental cost of converting resource into GDP; low resource intensity indicates a lower price or environmental cost of converting resource into GDP.Lorentzen, J. (ed) 2008. ''Resource intensity, knowledge and development: insights from Africa and South America.'' HSRC Press, South Africa. Resource productivity ...

Resource
''Resource'' refers to all the materials available in our environment which are Technology, technologically accessible, Economics, economically feasible and Culture, culturally Sustainability, sustainable and help us to satisfy our needs and wants. Resources can broadly be classified according to their availability as Renewable resource, renewable or national and international resources. An item may become a resource with technology. The benefits of resource utilization may include increased wealth, proper functioning of a system, or enhanced well. From a human perspective, a regular resource is anything to satisfy human needs and wants.WanaGopa - Nyawakan The concept of resources has been developed across many established areas of work, in economics, biology and ecology, computer science, management, and human resources for example - linked to the concepts of competition, sustainability, Conservation movement, conservation, and stewardship. In application within human society, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Intensity
Energy intensity is a Measurement, measure of the efficient energy use, energy inefficiency of an Economic system, economy. It is calculated as units of energy per unit of GDP (Gross Domestic Product) or some other measure of economic output. High energy intensities indicate a high price or cost of converting energy into GDP. On the other hand, low energy intensity indicates a lower price or cost of converting energy into GDP. The energy intensity of a country or region differs from its Efficient energy use, energy efficiency. Energy intensity is affected by climate, economic structure (e.g. services vs. manufacturing), trade, as well as the energy efficiency of buildings, vehicles, and industry. High energy intensity means high industrial output as portion of GDP. Countries with low energy intensity signifies labor intensive economy. Overview Many factors influence an economy's overall energy intensity. It may reflect requirements for general standards of living and weather ...

Resource Economics
Natural resource economics deals with the Supply (economics), supply, Demand (economics), demand, and Resource allocation, allocation of the Earth's natural resources. One main objective of natural resource economics is to better understand the role of natural resources in the economy in order to develop more Sustainability, sustainable methods of managing those resources to ensure their availability for future generations. Resource economists study interactions between economic and natural systems, with the goal of developing a sustainable and efficient economy. Areas of discussion Natural resource economics is a transdisciplinary field of academic research within economics that aims to address the connections and interdependence between human economies and natural ecosystems. Its focus is how to operate an economy within the ecological constraints of earth's natural resources.Encyclopedia of EarthArticle Topic: ecological economics/ref> Resource economics brings together and ...

Natural Resource Management
Natural resource management (NRM) is the management of natural resources such as Land (economics), land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations (stewardship). Natural resource management deals with managing the way in which people and natural landscapes interact. It brings together natural heritage management, land use planning, water management, Conservation biology, bio-diversity conservation, and the future sustainability of industries like agriculture, mining, tourism, fisheries and forestry. It recognizes that people and their livelihoods rely on the health and productivity of our landscapes, and their actions as stewards of the land play a critical role in maintaining this health and productivity. Natural resource management specifically focuses on a scientific and technical understanding of resources and ecology and the Life-supporting capacity of those resources. Env ...

Sustainability Metrics And Indices
Sustainability metrics and indices are measures of sustainability, using numbers to quantify environmental, social and economic aspects of the world. There are multiple perspectives on how to measure sustainability as there is no universal standard. Instead, different disciplines and international organizations have offered measures or Economic indicator, indicators of how to measure the concept. While sustainability indicators, indices and reporting systems gained growing popularity in both the public and private sectors, their effectiveness in influencing actual policy and practices often remains limited. Metrics and indices Various ways of operationalizing or measuring sustainability have been developed. Since the 2010s, there has been an expansion of interest in Sustainable Development Index (SDI) systems, both in industrialized and, albeit to a lesser extent, in developing countries. SDIs are seen as useful in a wide range of settings, by a wide range of actors: internatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermoeconomics
Thermoeconomics, also referred to as biophysical economics, is a school of heterodox economics that applies the laws of thermodynamics, laws of statistical mechanics to economic theory. Thermoeconomics can be thought of as the statistical physics of value theory, economic value and is a subfield of econophysics. It is the study of the ways and means by which human societies procure and use energy and other biological and physical resources to produce, distribute, consume and exchange goods and services, while generating various types of waste and environmental impacts. Biophysics, Biophysical economics builds on both social sciences and natural sciences to overcome some of the most fundamental limitations and blind spots of conventional economics. It makes it possible to understand some key requirements and framework conditions for economic growth, as well as related constraints and boundaries.

Systems Ecology
Systems ecology is an interdisciplinary field of ecology, a subset of Earth system science, that takes a holistic approach to the study of ecological systems, especially ecosystems. Systems ecology can be seen as an application of general systems theory to ecology. Central to the systems ecology approach is the idea that an ecosystem is a complex system exhibiting emergent properties. Systems ecology focuses on interactions and transactions within and between biological and ecological systems, and is especially concerned with the way the functioning of ecosystems can be influenced by human interventions. It uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems. Overview Systems ecology seeks a holistic view of the interactions and transactions within and between biological and ecological systems. Systems ecologists realise that the function of any ecosystem can be influenced by human economics in fundamental ways. They ...

Sustainable Development
Sustainable development is an approach to growth and Human development (economics), human development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs.United Nations General Assembly (1987)''Report of the World Commission on Environment and Development: Our Common Future''. Transmitted to the General Assembly as an Annex to document A/42/427 – Development and International Co-operation: Environment. The aim is to have a society where living conditions and resources meet human needs without undermining planetary integrity. Sustainable development aims to balance the needs of the Economic development, economy, Environmental protection, environment, and society. The Brundtland Report in 1987 helped to make the concept of sustainable development better known. Sustainable development overlaps with the idea of sustainability which is a Normativity, normative concept. Text was copied from this source, which is av ...

Sustainability Accounting
Sustainability accounting (also known as social accounting, social and environmental accounting, corporate social reporting, corporate social responsibility reporting, or non-financial reporting) originated in the 1970s and is considered a subcategory of financial accounting that focuses on the disclosure of non-financial information about a firm's performance to external stakeholders, such as capital holders, creditors, and other authorities. Sustainability accounting represents the activities that have a direct impact on society, environment, and economic performance of an organisation. Sustainability accounting in managerial accounting contrasts with financial accounting in that managerial accounting is used for internal decision making and the creation of new policies that will have an effect on the organisation's performance at economic, ecological, and social (known as the triple bottom line or Triple-P's; People, Planet, Profit) level. Sustainability accounting is often use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Dynamics
Population dynamics is the type of mathematics used to model and study the size and age composition of populations as dynamical systems. Population dynamics is a branch of mathematical biology, and uses mathematical techniques such as differential equations to model behaviour. Population dynamics is also closely related to other mathematical biology fields such as epidemiology, and also uses techniques from evolutionary game theory in its modelling. History Population dynamics has traditionally been the dominant branch of mathematical biology, which has a history of more than 220 years,Malthus, Thomas Robert. An Essay on the Principle of Population: Library of Economics although over the last century the scope of mathematical biology has greatly expanded. The beginning of population dynamics is widely regarded as the work of Malthus, formulated as the Malthusian growth model. According to Malthus, assuming that the conditions (the environment) remain constant ('' ceteris pari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Ecology
Industrial ecology (IE) is the study of material and energy flows through industrial systems. The global industrial economy can be modelled as a network of industrial processes that extract resources from the Earth and transform those resources into by-products, products and services which can be bought and sold to meet the needs of humanity. Industrial ecology seeks to quantify the material flows and document the industrial processes that make modern society function. Industrial ecologists are often concerned with the impacts that industrial activities have on the environment, with use of the planet's supply of natural resources, and with problems of waste disposal. Industrial ecology is a young but growing multidisciplinary field of research which combines aspects of engineering, economics, sociology, toxicology and the natural sciences. Industrial ecology has been defined as a "systems-based, multidisciplinary discourse that seeks to understand emergent behavior of c ...

Ecological Economics
Ecological economics, bioeconomics, ecolonomy, eco-economics, or ecol-econ is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economy, economies and natural ecosystems, both intertemporally and spatially. By treating the economy as a subsystem of Earth's larger ecosystem, and by emphasizing the preservation of natural capital, the field of ecological economics is differentiated from environmental economics, which is the mainstream economics, mainstream economic analysis of the environment. One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that Physical capital, physical (human-made) capital can substitute for natural capital (see the section on #Weak versus strong sustainability, weak versus strong sustainability below).
