چکیده

A spatial EMERGY model was created for Alachua County, Florida that was based on a generalized emergy diagram model for equal size (one-hectare) land area units. The diagram models each of the major inputs and storages of emergy that might occur in each land unit. A geographic information system (GIS) was used to create the model and study the spatial distribution of each EMERGY flow and storage included in the diagram. Previously published transformities were used to calculate EMERGY densities from estimated energy flows and storages associated with each land unit. These energy estimates were based on very detailed GIS databases. This paper repons on the results of the spatial Iransformities that were calculated for the land use classifications, urban planning units, and neighborhoods in the study area. These spatial transformities provide an energy quality measure that can be used for landscape analysis and planning.

Methodological considerations from a wastewater treatment case study in Kenya

Emergy methodology questions were raised during a case study where a Sugar factory effluent were treated in a pond system in the Lake Victoria watershed, and evaluated from a performance, cost and resource use perspective. This paper focus on the methodological questions, which were the following: (1) how should the emergy systems diagram be drawn when dealing with a system that is in the recyc...

EMERGY SYNTHESIS 4 : Theory and Applications of the Emergy Methodology

The value of an item in an environmental system can be determined from two independent perspectives: (1) the perspective of the donor which determines what was required to produce the item and (2) the perspective of the receiver which determines what the person that receives the item is willing to pay for it. These two perspectives give complementary views of the process of valuation, one from ...

Emergy analysis of greenhouse cucumber production in Sistan region

In the current century, agriculture sustainability and the reduction of environmental pressure are two main objectives of the management of agro-ecosystems that is challenged by energy inefficiency. In this respect, the present study assessed one of the most important planting systems in Sistan region by emergy analysis approach. It analyzed all inputs of greenhouse cucumber production system i...

Perpetuation of Partial Transformities through Sequential Analyses for Refined Emergy Accounting and Index Development

An elegant feature of emergy synthesis is its capability to integrate the diverse inputs required to operate a system into a single metric that represents the equivalent amount of energy of one type. However, integration also presents problems with 1) precise tracking of emergy flows from source to sink, 2) developing and estimating indices, 3) communicating results to non-emergy specialists, a...

Comparison of Principles for Allocating Emergy to Recycled Materials in Natural and Managed Ecosystems

Emergy Algebra rules may not allow for appropriate accounting of recycled material emergy. The loss of emergy is not permitted using Emergy Algebra rules, but is necessary to address recycling material. It has been proposed to use Dynamic Emergy Accounting so that emergy loss can be factored in when allocating emergy to material recycle pathways. However, systems are often evaluated at steady-s...
