Certain governments subsidize certain basic agricultural products in order to guarantee an adequate domestic production of them.
Situation
The government subsidizes certain products in the hopes of making sure there's adequate domestic production of them.
But the subsidies lead to more intense farming, which leads to soil exhaustion, which leads to reduced yields (i.e. lower production).

The stem asks for a situation similar
What was the relationship between the declared intent ("let's guarantee adequate domestic production of these crops!") and a circumstance relevant to it?
That last part is being real cryptic: a circumstance?
We got a causal chain with multiple "circumstances". subsidies >> intense >> soil >> reduced farming exhaustion yields
But we know the fundamental relationship between the intent of the plan and this causal chain is that the plan is kind of backfiring and leading to the something that undermines the intent.
The subsidies were meant to guarantee sufficient production of crops, but they are leading to drastically reduced yields.
