The forecasted data indicates a decline in sloes and plums production in the UK from 2024 to 2028, decreasing from 6.16 to 4.65 thousand metric tons. Without access to historical data for 2023, it's challenging to determine precise year-on-year percentage variations. However, the compound annual growth rate (CAGR) suggests an average yearly decrease over the five-year period is evident.

Future trends to watch for include:

Impact of climate change on crop yields.
Shifts in consumer preferences impacting demand.
Improved agricultural technologies potentially stabilizing or reversing declines.
