Comparison of Three Biogeochemical Process Models for Quantifying Greenhouse Gas Effects of Agricultural Management
This report is a detailed look at three biogeochemical process models that are widely used in the United States to quantify greenhouse gases (GHGs) from agriculture and other land uses.
Compiled by Lydia P. Olander and Daniella Malin
Carbon and Agriculture: Getting Measurable Results, providing an overview of the state of knowledge regarding achievement of measurable results in reducing agricultural greenhouse gases.
The Coalition on Agricultural Greenhouse Gases (C-AGG) seeks to mitigate climate change and benefit farmers by advancing the development and adoption of science-based policies, methodologies, protocols, and projects for GHG emissions reductions and carbon sequestration in the agricultural sector. C-AGG members are agricultural producers, scientists, GHG quantification experts, carbon investors, policy experts, and GHG project developers. This report is intended to provide information useful for designing policies and programs to realize agriculture’s potential contributions to GHG mitigation.
This report reflects the contributions of diverse participation in C-AGG and is intended to catalyze continued discussions. We anticipate that it will evolve over time as science, data and information improve and evolve. The report is not formally a consensus document, and the specific endorsement of the work as a whole has not been sought from either the participants or their respective organizations.
June 2009: Climate Webinar Resource links - please find all four presentations from our recent Webinar series here:
Carbon Trusts Crop Calculator,
Farmer Focused GHG Calculator,
DAYCENT Model Description - Testing and Application for GHG Emission Inventories,
Recordings of the Webinars can be found at the following links:
- Webinar 1 - featuring the DAYCENT and Carbon Trust tools.
- Webinar 2 - featuring the DNDC model and Farmer Focused GHG Calculator ("Unilever Tool").
- Webinar 3 - where we heard from participants and discussed the applicability of these tools to three purposes: The Stewardship Index for Specialty Crops, carbon footprinting, and decision support for farmers.
- We had a fourth Webinar that came out of the first three in which Earth Analytics Group demo'ed the CASA model. The recording from this can be found here and slides here.
With the support of the David and Lucile Packard Foundation, Sustainable Food Lab focuses Ag Climate work on investigating and incentivizing the role of agriculture in climate change mitigation - through both academic research and quantification of actual carbon performance from changed practices in pilot projects. Interested companies are now in a position to benefit from these resources for assistance investigating - and possibly implementing potential carbon savings from the field level practices in supply chains.
The Food Lab is creating a learning community of organizations (from both within and outside the Food Lab) exploring low-carbon farming techniques, experimenting with changes, and as promising experimental results emerge, quantifying and potentially monetizing the climate benefits that may result from larger scale versions of those experiments.
