Earth Observation for Inventory Webinars (29th Feb 2016) by Jagadeesh Yeluripati
A series of webinars are being held to share the outcomes of the UK-led project on Scoping the
potential for Earth Observation (EO) to provide agricultural activity data for inventory
compilation which supports the aims of the Global Research Alliance (GRA) on Agricultural
Greenhouse Gases
About the project
The project aimed to critically evaluate the ability of existing or near launch EO sensors to fulfil the data
requirements of the Agriculture, Forestry and Other Land Use (AFOLU) inventory. Information on priority data
requirements were collected through an international stocktake, and the project assessed the extent to which EO
data could fulfil some of these requirements. The international stocktake also gathered information on experiences
of using EO for inventory compilation and addressed whether such approaches represent cost saving against
existing survey methods.
Webinar objectives
Share the outcomes of the international stocktake on inventory activity data requirements and potential
and existing uses of EO (as well as perceptions of EO);
Identify opportunities for collaboration and capacity building;
Share details of international case studies on use of EO in inventory compilation and the results of a novel
UK case study;
An overall objective is to facilitate information sharing between inventory practitioners, EO specialists ...
Dr. Changsheng Li - Modeling GHG Emissions Based on Biogeochemical Concepts by
On Tuesday, June 16th, Dr. Changsheng Li delivered a GRAMP webinar titled "Modeling GHG Emissions Based on Biogeochemical Concepts". Dr. Li is a professor of Natural Resources at the University of New Hampshire's Institute for the Study of Earth, Oceans, and Space and is the principal developer of the De-Nitrification-De-Composition model (DNDC). His talk focused on fundamental biogeochemical concepts and he discussed their implementation in DNDC.

DNDC and ARB Rice Compliance Offset Protocol by Developer Staff0
In 2013, the California Air Resources Board (CARB) began the development of a new Compliance Offset Protocol for Rice Cultivation. This is the first agriculture land based offset protocol to be considered under the ARB compliance program. Rice producers can play a key role in helping California meet the emissions reduction goals required by Assembly Bill 32 through a reduction in methane emissions. Offsets are a crucial part of the cap-and-trade program in AB 32 because they provide compliance entities with less costly way to satisfy their cap.
The DNDC biogeochemical process model will be used to quantify changes in rice methane emissions due to the eligible practices. Initially projects would be limited to the major rice growing regions in California and the Mid-South (Arkansas, Missouri, Mississippi, Louisiana, and Texas) for which the DNDC model has been calibrated with field measurements of methane emissions. ARB is considering the following management changes as eligible practices for offset: 1) replacing wet seeding with dry seeding, 2) early drainage at the end of growing season, and 3) rice straw removal after harvest; and 4) intermittent flooding.
