The seed planter helping sesame farmers in Tanzania

Ranked third in the world, Tanzania is Africa's largest exporter of sesame seeds.

The traditional way of planting these seeds is slow and arduous work, but one man is changing that.

Entrepreneur Martin Constantine has invented a hand-pushed planting machine, making the job much easier.

The BBC's Sammy Awami has been to meet him for Africa Business Report.
