[1] Hamzat is also the Chief Executive of Connected Development (CODE), a non-governmental organization that is empowering marginalised communities in Africa with access to information on how to better engage their government for the implementation of public services.

He later worked as an information technology specialist with International Centre for Energy, Environment and Development (ICEED)[4] during which his passion for climate change grew.

[8] #SaveBagega was a viral campaign that started off on Twitter when Hamzat first used the hashtag when he tweeted about the lead poisoning incident in Bagega, Zamfara State.

[9] In May 2012, Doctors Without Borders had reported that least 4,000 children are suffering from lead poisoning as a result of artisanal gold mining in Zamfara State in Nigeria.

[10] Later the same year, Human Rights Watch further called on the Nigerian government who had pledged close to US$5 million to clean up areas that had been contaminated with lead during artisanal gold mining operations because of high levels of lead in rock ore. At the time of Human Right's Watch participation in #SaveBagega, more than 400 children were reported dead and many of the children could not be treated.
