[NY Times] Africa’s agricultural yields are less than half the global average, and about 25 percent of what they could potentially yield. Agricultural productivity in Africa is growing at about half the rate the population is growing.
Africa has long been a continent of small farmers, half of them women, raising maize with no fertilizer, pesticide or irrigation, on a tiny plot with a hoe. Now the little these farmers have is endangered by drought. Climate change is making Africa’s weather more extreme and erratic. Africa loses about a fifth of its maize crop because of drought. In many years, the loss is near-total. A survey of farmers in 12 countries found that in the last decade, they averaged about three wipeout years.
In 2000, the first seeds for drought-tolerant maize were planted in Malawi and Zimbabwe. Now three million farmers in 13 countries in Africa are using them. (All these strains are conventionally bred, not genetically modified.)
“One drought is something that throws farmers back into poverty,” said Bänziger. “They lose everything. During a severe drought, a farmer may harvest 5 percent of the ears of a normal crop. With drought-tolerant maize, the farmer can get 50 percent. We want to get to the point where we can save every plant.”
Pesticides and inorganic fertilizers are bad for the environment. But this is not an argument that anyone who eats in America should be making to African subsistence farmers. In 2006, an African Union Declaration on agriculture adopted the goal of 50 kilograms of fertilizer per hectare planted. At the time, Africa was using only eight kilos per hectare; America was using 120. Africa needs vastly more fertilizer use, not less.
The Green Revolution failed in Africa for reasons that remain major obstacles today. Absent research, roads, storage, extension capacity, credit and subsidies — high-yield maize will produce little, or its gains will go only to wealthier farmers.
Nation Master shows that the lowest agricultural yields are in Africa [mainly 2008 statistics]. Below are kilograms cereal grain yields per hectare. Developed countries have about 6000+ kg per hectare and the world average is about 3500 kilograms per hectare.
