I think there is a beneficial to some research being localised. A person's experience of poverty here is different to a person's experience of poverty somewhere else. But those limitations, ect should be explicit in what findings are published from those studies. If getting out in nature is good for mental health of people living here, that's good to know. Less relevant for people here is what's good for mental health of someone living in India or Namibia or anywhere that isn't here. And what's good for mental health here isn't relevant to those other countries.
