The first mission of the Swiss Humanitarian Aid Unit was deployed to Lake Chad 50 years ago. The very first mission of the Swiss Humanitarian Aid Unit was deployed in 1974 to the Lake Chad region (Niger, Chad, Nigeria and Cameroon), which had been hit by a terrible drought. The stamp pays tribute to the remarkable efforts of the unit’s 80 members, who worked side by side with local people to improve the situation. It took several months to build storage facilities and hospitals, repair wells and distribute around 260 tonnes of grain.
