Published in the US Proceedings of the National Academy of Sciences (Howden S M, Soussana J-F, Tubiello F N, Chhetri N, Dunlop M, and Meinke H (2007), this article argues that at a moderate level of climate change there are many adaptation options available for agricultural systems, but under more severe climate change these adaptive measures may not be adequate. An integrated approach to dealing with climate change is needed.

Defra project AC0206 (2007) aims to review key scientific research reports on agriculture and climate change and other information about relevant agricultural practices which have already been adopted (in the UK and overseas) in order to identify good practice by farmers and land managers to reduce greenhouse gas emissions and highlight the main gaps in knowledge that may require further research.

There is ongoing and considerable interest in the organic versus conventional question. Do organic systems generate higher or lower levels of greenhouse gas emissions? There are a great many studies, and a great many different conclusions. Some examples are as follows: Evaluation of conventional and organic agricultural production in relation to primary energy inputs and certain pollution gas emissions, summary of report commissioned by the Federal Ministry for Food, Agriculture and Forestry (BML), Bonn, Murphy DPL, Roever M and Heinmeyer O., 2000.

The Welsh Assembly Government has published a report setting out how the agriculture and rural land use sectors in Wales can play play their part in reducing greenhouse gas emissions while maintaining food production. The report was commissioned by the Welsh Assembly and undertaken by the Land Use Climate Change Group, chaired by Professor Gareth Wyn Jones, with representatives from farming, forestry, research and environmental sectors. It is entitled Land Use Climate Change Report To Welsh Assembly Government, March 2010.

In August 2009, Defra published a report by ADAS entitled: Analysis of Policy Instruments for Reducing Greenhouse Gas Emissions from Agriculture, Forestry and Land Management (project code RMP/5142).
