Add herbicides to Africa's rescue plan!

"What should Africa do? The same thing First World farmers do in this age of technology—use herbicides. In a Nigerian test plot, atrazine on the corn crop doubled yields and cut costs by 60 percent. On peanuts, in Zimbabwe, herbicides cut weed control labor from 100 hours per hectare to one-fourth of an hour per hectare while yields rose sharply."

Add herbicides to Africa's rescue plan! 

CHURCHVILLE, VA: Africa is the only continent where food production per capita is falling as its population continues to expand. Three-fourths of Africa’s food is produced on small farms that get radically lower crop yields than its experimental farms.
Even if these little farms got adequate fertilizer and high-yield seeds, they still wouldn’t get the higher yields produced by First World farmers because of the heavy weed populations fostered by Africa’s high temperatures, high humidity, and intense sunlight. A Nigerian field has an estimated 200 million weed seeds per hectare! 
 African women are courting disabling diseases as they spend 300 hours per hectare per season to hand-weed a field of corn. The weeds also limit too many African families to one acre of low-yield corn per year. The kids are weeding instead of going to school because the family has to eat. The men have gone to the cities because poor roads mean they can’t earn a living selling farm products from their villages, even if they were able to produce extra food for sale. AIDS has cut the available farm labor by at least 10 percent, and malaria by more than that. The healthy must spend their time nursing the ill.
African governments are now pinning hopes on fertilizer as a crucial input to raise food yields and meet its fast-rising food needs without plowing down more wildlife habitat. Putting only fertilizer on a weedy corn plot can, unfortunately, increase yield losses! Weeds can often out-compete crop plants for the nitrogen in the soil. That is why the International Fund for Agricultural Development (IFAD) reported as early as 1998 that crop yields in Africa would stay at the subsistence level as long as the hand-hoe is the primary means of weeding.
