I think there may be a slight issue with the text you provided. It appears to be a news article or a press release, but it's not clear what "la casera" refers to. Could you please provide more context or clarify who or what "la casera" is?

Assuming "la casera" is a person or an organization, it seems that they have paid a courtesy visit to the Emir of Kano, a traditional ruler in Nigeria. According to the text, "la casera" has promised national growth, which could imply that they have discussed ways to promote economic development or improve the overall well-being of the country.

If you could provide more information about "la casera" and the context of the visit, I'd be happy to help you analyze the significance of the visit and the promises made.
