Life Cycle Assessment

The Life Cycle Assessment (LCA) collection is a catalog and archive of data, tools, and resources that support LCA for agriculture and related areas of research. It is complementary to the USDA LCA Commons Life Cycle Inventory (LCI) database, and provides access to a wider range LCA data and tools.

Life Cycle Assessment (also known as life cycle analysis, or cradle-to-grave analysis) is a method of assessing environmental impacts associated with all stages of a product's life. For example, it measures impact from raw material extraction to materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling. The goal of LCA is to compare the full range of environmental effects assignable to products and services by quantifying all inputs and outputs of material flows, and then assessing how these material flows impact the environment. This information is used to improve processes, support policy, and provide a sound basis for informed decisions.

Unit process data for field crop production version 1

These unit process models represent crop production in US states in multiple years. The main data source used for the development of the field crop data described here is the annual USDA Agricultural Resource Management Survey (ARMS). ARMS data are from an annual national survey of field-level farm practices sponsored jointly by USDA Economic Research Service (ERS) and the USDA National Agricultural Statistics Service (NASS). These datasets were released in ecospold version 1 in June 2012.
