Urgent and open debate is needed around Wales' food system in order to achieve net zero, academics at Cardiff University conclude.
The Wales Centre for Public Policy (WCPP) has published its response to the Wales Net Zero 2035 Challenge Group's first challenge question 'How could Wales feed itself by 2035?' The report examines the evidence and explores challenges facing the agricultural sector, which is set to be the largest source of greenhouse gas emissions in 2035, as other sectors decarbonise more quickly.
Direct methane emissions from livestock currently make up 61% of agricultural emissions in Wales with manure management contributing an additional 14% of emissions.
By making significant adjustments to farming and land use, the paper argues that Wales could make up for lost time in the race to achieve net zero.
According to the evidence, some agricultural land will need to be used in ways that add to our carbon sinks, such as increasing our woodland, forestry and peat bogs. Reducing agricultural emissions will also require a reduction in livestock numbers.
The new Agriculture Bill will be a key mechanism for the Welsh Government to shape land management practices but, the report adds, there should be an increased focus on reducing overall emissions. Any changes to agricultural policy must also ensure affected livestock farmers are supported, the report concludes.
Dr Helen Tilley, WCPP Senior Research Fellow, said: "It is clear from our work on this topic that there are multiple, deeply entrenched and interconnected obstacles to the sustainability of Wales' land use, farming and food systems; but the evidence also helps us identify some important opportunities for change.
