My research has shown that as the Green Revolution project reaches its 2020 deadline, crop productivity has grown slowly, poverty remains high, and the number of hungry people in the 13 countries that have received priority funding has risen 30% since 2006. Few small-scale farmers have benefited. Some have been thrown into debt as they try to pay for the high costs of the commercial seeds and synthetic fertilizer that Green Revolution proponents sell them. This disappointing track record comes in spite of $1 billion in funding for AGRA and $1 billion per year in subsidies from African governments to encourage their farmers to buy these high-priced inputs.

For the last 14 years, governments and donors have bet heavily, and almost exclusively, on the Green Revolution formula of commercial inputs, fossil-fuel-based fertilizers and agro-chemicals. That gamble has failed to generate agricultural productivity, even as the continent has seen a strong period of economic growth. Rural poverty remains high. Hunger is rampant, with the United Nations warning that Africa could see a 73% surge in undernourishment by 2030 if policies don’t change

agroecology, with its innovative combination of ecological science and farmers’ knowledge and practices, can restore degraded soils, make farms more resilient to climate change, improve food security and nutrition by growing and consuming a diversity of crops, all at a fraction of the cost — to farmers and to African governments — of the Green Revolution approach

AGRA, initiated in 2006, heralded a new campaign to bring the kind of input-intensive agriculture to Africa that had failed to take hold on the continent when the first Green Revolution swept through much of Asia and Latin America in the 1960s and 1970s.
-
AGRA worked with governments to speed the development of high-yield commercial seeds designed for Africa’s wide range of soils and climates and to facilitate the delivery to farmers of those seeds and the inorganic fertilizers that would make them grow.
-
Many warned that it was seeking to impose Western technologies inappropriate for the continent’s soils, farmers and food systems. Some decried the lack of consultation with African farmers on the nature of the interventions.9 Others pointed out the serious flaws in the first Green Revolution: water supplies depleted and contaminated with chemical runoff; farmers indebted due to high input costs while yields declined after their initial increases; and the loss of crop and diet diversity as Green Revolution crops took over the countryside
-
African farm groups like the Alliance for Food Sovereignty in Africa (AFSA) also warned of the loss of food sovereignty, the ability of communities and nations to freely choose how they wanted to feed themselves, as large commercial firms could come to dominate local markets backed by new government policies designed to ensure market access.

Only one country, Ethiopia, shows anything resembling the combination of yield growth and hunger reduction Green Revolution proponents promised, with a 73% increase in productivity and a 29% decrease in the number of hungry. Note, however, that neither of these is on track to meet AGRA’s goal of doubling productivity (100% increase) and halving the number of hungry (which would be a 50% decrease). Ghana is the only other AGRA country that shows decent productivity growth with some decrease in hunger. Malawi achieved relatively strong yield growth but only a small reduction in undernourishment.

These data suggest that Green Revolution programs have not produced a productivity boom through intensification but rather an extensification onto new lands. The promotion of extensification is a serious contradiction for Green Revolution proponents. The explicit goal of “sustainable intensification” is to minimize pressure on land and water resources while limiting further greenhouse gas emissions. To the extent Green Revolution programs are encouraging extensification, they are at odds with national and donor government commitments to mitigate climate change. Depending on individual countries’ land endowments, extensification can be a serious problem. Rwanda, for example, is densely populated and does not have vast tracts of uncultivated arable land.

Evidence would suggest that the main beneficiaries are likely not the poorest or most food-insecure farmers but rather a growing number of medium-scale farmers who have access to more land and are already integrated into commercial networks. Only a fraction of such farmers come up from the ranks of smallholders; many are new investors in farming from urban elites. One study showed that a tiny fraction of smallholders is likely to become commercial farmers.18

Cassava, a key staple in Nigeria, Mozambique, Uganda, Tanzania and many other AGRA countries, saw a 6% decline in yields. Overall, roots and tubers, which include nutritious crops such as sweet potatoes, experienced a 7% decline in yields. Groundnuts, another critical staple source of protein in many countries, saw an alarming 23% drop in yields.
-
The Staple Crop Index shows that Rwanda’s apparent success in maize has come at the expense of more comprehensive food crop productivity.
-
The total number of undernourished in AGRA’s 13 countries has increased from 100.5 million to 131.3 million, a 30% increase, from before AGRA to 2018. Only Ethiopia, Ghana and Mali report a significant decline in the absolute number of chronically hungry residents
-
One of the negative consequences of the Green Revolution focus on maize and other commodity crops is the declining importance of nutritious and climate-resilient crops like millet and sorghum, which have been key components in healthy diets. These are rarely supported by African governments or AGRA; meanwhile, input subsidies and supports for maize and other favored crops provide incentives for farmers to decrease the cultivation of their own crop varieties
-
AGRA seems to be feeding Africa’s worrisome trend toward locking in path dependency on input-intensive agriculture, much to the detriment of smallholder farmers
-
Unlike industrial-scale farmers in developed countries, their path has not yet been determined; there remain opportunities to chart paths different from the high-input agriculture model promoted by AGRA.

Agroecology is one of the systems giving farmers the kinds of innovation they need, farming with nature to promote the soil-building practices that Green Revolution practices often undermine. Building on farmers’ knowledge of local conditions and food cultures, multiple food crops are grown in the same field. Compost, manure and biofertilizers — not fossil-fuel-based fertilizer — are used to nourish fields. Biological pest control decreases pesticide use. Researchers work with farmers to improve the productivity of their seeds rather than replacing them with commercial varieties farmers need to buy every year and douse with fertilizer to make them grow.25 AFSA has documented the effectiveness of agroecology, now widely promoted among its member organizations as a key step toward food sovereignty.26 Such initiatives also achieve productivity increases more impressive than those achieved by Green Revolution programs. One University of Essex study surveyed nearly 300 large ecological agriculture projects across more than 50 poor countries and documented an average 79% increase in productivity with decreasing costs and rising incomes.27 Such results far surpass those of the Green Revolution.

It is time for international donors and African governments to change course, to shift their agricultural development funding toward the kinds of low-input sustainable farming that many small-scale farmers in Africa are pioneering under the banner of agroecology. With substantial support, like that provided to Green Revolution programs, agroecology can be Africa’s food future
