What does the "scope" mean in this circumstance?
Native speaker’s answer

Here, “scope” means “extent,” “range,” “reach,” or “breadth.” You can understand it as the speaker meaning that although the humanitarian effects have been great, it is difficult to measure the extent (how much) of the change caused. Ex: Although I am an expert, this is beyond my scope. Ex: The scope of my book covers the history, politics, and culture of the country.
