Earlier this year, in response to a high-level UN meeting on NCDs in 2011, the World Health Assembly set a global target to reduce premature NCD mortality by 25% by the year 2025.
Swansea University economics professor David Blackaby said the assembly government's employment target was put in place in June 2007 when the economy was booming.
This year the garden looks set to beat its target of 130, 000 visitors, supporting an assembly audit committee report which found it was now on a firmer financial footing.
