The latest edition of Agricultural Statistics and Climate Change, published by Defra and National Statistics, shows that emissions of major greenhouse gases (GHGs) from the sector have fallen.
Total estimated GHG emissions fell 19% from 1990 to 2013, with the biggest falls in carbon dioxide (31%), followed by nitrous oxide and methane which dropped 17% each. Methane accounted for the largest proportion of gases at 27 million tonnes CO2e in 2013. Total productivity rose over the same period according to the report.
However, the output of vegetables and other horticultural products fell between 1990 and 2014, although at 86.7% of the 1990 index the 2014 figure was still higher than 2012 which was the lowest period. According to the statistics the sector accounts for 10% of total GHG emissions from agriculture. ‘Improved nitrogen use efficiency in cropping systems can be achieved through improved crop nutrient management,” comment the authors.
