Nema renders aid to nigerian refugees in cameroun

I think there may be a few issues with the sentence you provided.

Firstly, I'm assuming you meant to say "NEMA" stands for National Emergency Management Agency, which is a Nigerian government agency responsible for coordinating disaster response and relief efforts.

Secondly, I'm not aware of any Nigerian refugees in Cameroon. Nigeria and Cameroon have a shared border, and while there may be some cross-border movements of people, I'm not aware of any significant refugee crisis or displacement of Nigerians in Cameroon.

That being said, if you're referring to a specific incident or event where NEMA has provided aid to Nigerian refugees in Cameroon, I'd be happy to help you find more information on that. Could you please provide more context or clarify what you're referring to?
