Why does this Öko-Institut care about reducing emissions in farming?

According to https://www.mdr.de/wissen/deutschland-top-fuenf-klima-emissionen-100.html emissions of farming is negligible. Even if they change anything, probably with great effort, they wouldn't change anything. They are the least who need to care.
Already mentioned this in a subcomment. Your graph is about CO² specifically. The oeko institut talks about emissions from lifestock, which is mostly methane and a very significant and potent overall contribution to global warming.
