Change in the vulnerability of agriculture to pollinator decline

The change in agriculture's vulnernability to declines in pollinator populations from 1961 to 2016. Higher positive numbers indicate it has become more vulnerable
(red); negative indicates less vulnerable (blue).

A country is more vulnerable if a lot of its output comes from pollinator-dependent crops and it has low levels of crop diversity. This makes its food system dependent
on the growth of only a few crops.
