The scope of agriculture & its branches
Narrated lesson · press play
Stand at the gate of a big farm outside Otjiwarongo and look around. There is a field of maize, a herd of cattle, a tractor, a workshop, a row of trees, and an office with the farmer working out prices. Which of these is 'agriculture'? The surprising answer is: all of them. In this lesson we open up the full scope of agriculture — from the seed in the sand to the food on the shop shelf — and meet every branch of the subject and how they work together on one Namibian farm.
