In this video Paul Andersen explains how matter and energy are conserved within the Earth's system. Matter is a closed system and Energy is open to the surroundings. In natural systems steady state is maintained through feedback loops but can be be affected by human society.

What is ENVIRONMENTAL SYSTEMS ANALYSIS? What does ENVIRONMENTAL SYSTEMS ANALYSIS mean?

What is ENVIRONMENTAL SYSTEMS ANALYSIS? What does ENVIRONMENTAL SYSTEMS ANALYSIS mean? ENVIRONMENTAL SYSTEMS ANALYSIS meaning - ENVIRONMENTAL SYSTEMS ANALYSIS definition - ENVIRONMENTAL SYSTEMS ANALYSIS explanation.

Source: Wikipedia.org article, adapted under license.

Environmental systems analysis (ESA) is a systematic and systems based approach for describing human actions impacting on the natural environment to support decisions and actions aimed at perceived current or future environmental problems. Impacts of different types of objects are studied that ranges from projects, programs and policies, to organizations, and products. Environmental systems analysis encompasses a family of environmental assessment tools and methods, including life cycle assessment (LCA), material flow analysis (MFA) and substance flow analysis (SFA), and environmental impact assessment (EIA), among others.

ESA studies aims at describing the environmental repercussions of defined human activities. These activities are mostly effective through use of different technologies altering material and energy flows, or (in)directly changing ecosystems (e.g. through changed land-use, agricultural practices, logging etc.), leading to undesired environmental impacts in a, more or less, specifically defined geographical area, and time, ranging from local to global. The basis for the analytical procedures used in ESA studies is the perception of flows of matter and energy associated to causal chains linking human activities to the environmental changes of concern. Some methods are focusing different parts or aspects of the energy/matter flows or the causal chains, where flow models like MFA or LCA deals with the more or less human controlled societal flows while, e.g. ecological risk assessment (ERA) is related to disentangling environmental causal chains. Environmental systems analysis studies has been suggested to be divided between full and attributional approaches. The full mode covers identified material and energy flows and associated processes leading to environmental impacts. The attributional approach, on the other hand, is based on an analysis of the processes needed to fulfil a certain purpose such as the function that a product delivers. The combination of methods (e.g. LCA and environmental risk assessment) has also been of interest

Methods can be grouped into procedural and analytical approaches. The procedural ones (e.g. EIA or strategic environmental assessment, SEA) focus on the procedure around the analysis, while the analytical ones (e.g. LCA, MFA) put the main focus on technical aspects of the analysis, and can be used as parts of the procedural approaches. Regarding the impacts studied, the environmental issues cover both effecs of natural resource use and other environmental impacts, e.g. due to emissions of chemicals, or other agents. In addition, environmental systems analysis studies can cover or be based on economic accounts (life cycle costing, cost-benefit analysis, input-output analysis, systems for economic and environmental accounts), or consider social aspects. The objects of study are distinguished into five categories.

Environmental Economics

021 - Environmental Economics

In this video Paul Andersen explains how economic models, like supply and demand, can be applied to environmental systems. The market forces will not protect environmental services until proper valuation and externalities are established. The wealth of a nation can be more accurately measured through the sustainability of the economic model.

UC Merced Graduate Studies: Environmental Systems

The Environmental Systems graduate program trains students to tackle the most challenging problems facing our planet -- water, soil, climate, energy and resources. Through understanding the Earth as an integrated system of atmosphere, hydrosphere, lithosphere and biosphere that intersects human society, ES students are uniquely poised to address critical research needs of the environment and its sustainability. Graduates are prepared for careers in academia, research, government and industry that integrate expertise from across engineering, natural sciences and social sciences.

Socio-Environmental Systems By Design

Socio-Environmental Systems by Design assessed outcomes of engineered landscapes and intentional efforts to alter, manage, or direct the structure and functioning of socio-environmental systems. It involved ​governance, urban planning, infrastructure, environmental justice, synthetic biology solutions, technology, conservation or protected areas, scientific inquiry, and knowledge production. Key take-aways from the theme include the importance of tangible products in order to engage the public and stakeholders and encourage involvement as well as encouraging taking academic risks and embracing being a novice outside of the academic community.

Nasuni Customer Story: Environmental Systems Design (ESD)

The global architecture and engineering firm Environmental Systems Design, Inc., had enough capacity to handle its data.
The challenge was protecting that data. The firm would often have 15TB of data in production at a given time and its existing backup solutions simply could not keep pace. After quickly outgrowing several other systems, ESD turned to Nasuni’s enterprise storage as a service. Now, thanks to Nasuni’s automated backup, which delivers unlimited versioning, fast disaster recovery
and an unmatched RPO, IT can stop worrying about backup and focus on its core mission of enhancing business productivity.
