Pioneer of sustainable agriculture calls for intensification of farming
In a lecture to the Stanford community Tuesday night, Professor Sir Gordon Conway argued that sustainably intensifying agriculture, especially in Africa, is the only way to feed a growing global population without greatly expanding the amount of land used for farming. Sir Gordon is an agricultural ecologist and was an early pioneer of sustainable agriculture while working in Malaysia in the 1960s. He is now a professor of international development at Imperial College London and the director of Agriculture for Impact, a project funded by the Bill and Melinda Gates Foundation.
Sir Gordon's lecture, "Can Sustainable Intensification Feed the World?" was the second installment of the Food and Nutrition Policy Symposium Series sponsored by the Center on Food Security and the Environment.
Sir Gordon described three major challenges to ensuring future global food security: food prices are higher and more volatile, one billion people are malnourished (including 1 in 5 children), and rising demand means that 60 to 100 percent more food will be needed to feed the world by 2050. Solving the food security crisis will mean improving both the quantity and the nutrition of food, at stable and affordable prices, in the face of major challenges.
These challenges include factors on the demand side of the global food economy, such as population growth, changing diets, and the use of crops for biofuels. Supply side factors like high fertilizer prices, climate change, and scarcity of land and water put even more pressure on the food system.
The solution, Sir Gordon said, is agricultural intensification, a set of practices that allow farmers to produce more food with existing land and water. Sustainability is a key component, so that intensification does not also raise greenhouse gas emissions, deplete soil quality, or damage the resilience of farming systems. Sustainable intensification will be especially important in Africa, said Sir Gordon, where population growth and dietary changes will be most dramatic, and where currently crop yields are far below most other areas of the world.
Farmers, scientists and policymakers can take several approaches to sustainable intensification. An ecological approach includes practices that safeguard environmental resources and reduce farmers’ dependence on chemicals like herbicides and pesticides, such as through organic farming, integrated pest management, agroforestry or conservation agriculture. A genetic intensification approach includes developing better plant varieties, with traits that promote more sustainable agriculture by resisting pests and diseases, or that provide more nutrition. A third approach is socio-economic intensification of agriculture, through the development of farmers’ cooperatives, better links between farmers and markets, and improved access by farmers to insurance and credit.
The goal, Sir Gordon said, is to help farmers “build resilient livelihoods” that will withstand economic and environmental shocks in the coming decades. Good science is important, but strong political leadership, especially within Africa, will be just as crucial.
Can we feed the world in the 21st century?
In a recent speech, Stanford professor Rosamond Naylor examined the wide range of challenges contributing to global food insecurity, which Naylor defined as a lack of plentiful, nutritious and affordable food. Naylor's lecture, titled "Feeding the World in the 21st Century," was part of the quarterly Earth Matters series sponsored by Stanford Continuing Studies and the Stanford School of Earth Sciences. Naylor, a professor of Environmental Earth System Science and director of the Center on Food Security and the Environment at Stanford, is also a professor (by courtesy) of Economics, and the William Wrigley Senior Fellow at the Freeman Spogli Institute for International Studies and the Stanford Woods Institute for the Environment.
"One billion people go to bed day in and day out with chronic hunger," said Naylor. The problem of food insecurity, she explained, goes far beyond food supply. "We produce enough calories, just with cereal crops alone, to feed everyone on the planet," she said. Rather, food insecurity arises from a complex and interactive set of factors including poverty, malnutrition, disease, conflict, poor governance and volatile prices. Food supply depends on limited natural resources including water and energy, and food accessibility depends on government policies about land rights, biofuels, and food subsidies. Often, said Naylor, food policies in one country can impact food security in other parts of the world. Solutions to global hunger must account for this complexity, and for the "evolving" nature of food security.
As an example of this evolution, Naylor pointed to the success of China and India in reducing hunger rates from 70 percent to 15 percent within a single generation. Economic growth was key, as was the "Green Revolution," a series of advances in plant breeding, irrigation and agricultural technology that led to a doubling of global cereal crop production between 1970 and 2010. But Naylor warned that the success of the Green Revolution can lead to complacency about present-day food security challenges. China, for example, sharply reduced hunger as it underwent rapid economic growth, but now faces what Naylor described as a "second food security challenge" of micronutrient deficiency. Anemia, which is caused by a lack of dietary iron and which Naylor said is common in many rural areas of China, can permanently damage children's cognitive development and school performance, and eventually impede a country’s economic growth.
Hunger knows no boundaries
Although hunger is more prevalent in the developing world, food insecurity knows no geographic boundaries, said Naylor. Every country, including wealthy economies like the United States, struggles with problems of food availability, access, and nutrition. "Rather than think of this as 'their problem' that we don't need to deal with, really it's our problem too," Naylor said.
She pointed out that one in five children in the United States is chronically hungry, and 50 million Americans receive government food assistance. Many more millions go to soup kitchens every night, she added. "We are in a precarious position with our own food security, with big implications for public health and educational attainment," Naylor said. A major paradox of the United States' food security challenge is that hunger increasingly coexists with obesity. For the poorest Americans, cheap food offers abundant calories but low nutritional value. To improve the health and food security of millions of Americans, "linking policy in a way that can enhance the incomes of the poorest is really important, and it's the hard part,” she said.” It's not easy to fix the inequality issue."
Success stories
When asked whether there were any "easy" decisions that the global community can agree to, Naylor responded, "What we need to do for a lot of these issues is pretty clear, but how we get after it is not always agreed upon." She added, "But I think we've seen quite a few success stories," including the growing research on climate resilient crops, new scientific tools such as plant genetics, improved modeling techniques for water and irrigation systems, and better knowledge about how to use fertilizer more efficiently. She also said that the growing body of agriculture-focused climate research was encouraging, and that Stanford is a leader on this front.
Naylor is the editor and co-author of The Evolving Sphere of Food Security, a new book from Oxford University Press. The book features a team of 19 faculty authors from 5 Stanford schools including Earth science, economics, law, engineering, medicine, political science, international relations, and biology. The all-Stanford lineup was intentional, Naylor said, because the university is committed to interdisciplinary research that addresses complex global issues like food security, and because "agriculture is incredibly dominated by policy, and Stanford has a long history of dealing with some of these policy elements. This is the glue that enables us to answer really challenging questions."
Earth Matters: Feeding the World in the 21st Century
Meeting the world’s need for food in the 21st century presents unprecedented challenges and opportunities. The global population is expected to grow toward 9 billion by 2050, and more families will live in middle-income countries and urban areas with expanding per capita consumption. At the same time, climate change and resource constraints will likely reduce crop and animal production in many locations, potentially creating greater disparities in incomes, food access, and nutrition around the world. Roz Naylor, a thought leader in global food security, will discuss the world’s future food dilemma and present a range of solutions focused on the diversification of food systems, improved input efficiencies, renewable energy use, new crop technologies, and policy adjustments. Her talk will demonstrate how food security, in its broadest form, is tied to security of many other kinds: energy, water, climate, health, the environment, and national security.
FSE director Roz Naylor’s research focuses on economic and biophysical dimensions of food security and environmental impacts of crop and animal production. Her extensive field research and published work span issues related to intensive crop production, aquaculture and livestock systems, biofuels, climate change, food price volatility, and food policy analysis. At Stanford, Naylor teaches courses on the world food economy, humanenvironment interactions, and sustainable agriculture.
Naylor's new book The Evolving Sphere of Food Security (Oxford University Press, September) brings together 19 Stanford scholars from across campus to explore the many faces and facets of global food security. Copies of the book will be available for purchase at the event.
The annual Earth Matters lecture series is jointly sponsored by Stanford Continuing Studies and the Stanford School of Earth Sciences.

Child health in Kenya improves with access to clean water
Children in rural Kenya are more susceptible to disease and death the farther away they live from clean drinking water, according to Stanford researchers.
In a survey of families in Asembo – a small farming community at the edge of Lake Victoria that has high rates of chronic diarrhea, child malnutrition and child death – a research team from the Center on Food Security and the Environment found that most people live just over a quarter-mile from clean water sources. About 200 feet closer to home are ponds and springs contaminated with E. coli bacteria. Sixty-six percent of families primarily use this contaminated surface water for drinking.

While water is essential for farming, collecting it is time-consuming and physically exhausting in remote places like Asembo. Previous research has shown that when families must travel long distances for water, child health suffers. The harder it is to collect, the less of it a family will use. A shortage of water for cooking and drinking compromises children’s nutrition and hydration. And it limits hand washing and bathing, making children more susceptible to disease. Quality and availability of water also varies widely from source to source, and the time required to collect water can force families to use dirtier, unimproved water sources that are closer to home.
In 2011, the FSE researchers partnered with the Centers for Disease Control Kenya Medical Research Institute (CDC-KEMRI), which was already conducting an extensive survey of household-level health indicators in the region. Combining resources with CDC-KEMRI allowed the team – led by FSE Director Rosamond Naylor, a professor of environmental earth system science, and Jenna Davis, an assistant professor of civil and environmental engineering – to use a robust set of data. The information covered about 3,000 households in a five kilometer radius and was collected on a bi-weekly basis for six months. In exploring the links between water, food and health in Asembo, FSE researchers first expanded the definition of water “access” to account for both physical distance and the quality of water sources.

Researchers then mapped the distance of each household from its nearest water source, and recorded whether the source was improved (such as a deep borewell) or unimproved (surface water like a pond, spring or shallow well). To get the most precise possible data on local water quality, the research team collected samples from each household’s water source and sent them to a local hospital lab for testing. Surveyors then collected data on each household’s water management practices, including water treatment. They measured agricultural output, dietary diversity, and perceived food insecurity, then recorded the weight and height measurements of each child in the household. Respondents also reported the frequency of recent cases of diarrheal disease among children of the household.
Results of the initial survey highlight sobering realities about water access in Asembo. Households in the survey reported average per capita water consumption of only 31 liters per day, including water used for cooking, drinking, hygiene and agriculture. The average walk time to the nearest water source was approximately 15 minutes. The average distance to the nearest improved source was 428 meters, whereas the average distance to unimproved surface water was 374 meters. Water quality tests confirmed that these sources, used by the majority of families, were highly contaminated with E. coli bacteria, while improved water sources were significantly cleaner. Thirty percent of children showed stunted growth, and 11 percent were underweight for their age.

Researchers found that close proximity to an abundant water source, regardless of quality, correlated with an increase in food production and diversity, as well as a lower hunger score. Having enough extra water for crop irrigation clearly improves children’s diets – particularly their access to the micronutrients essential for normal physical and cognitive development – and helps them resist disease. Households further from water sources reported lower and less diverse crop yields, as well as poorer child health indicators. Quality was also an important factor, as households with access to clean, improved water reported better child health outcomes than those relying on contaminated surface water.
The ultimate goal of the project, “Rural health and development at the food-water nexus” is to design interventions and policy incentives that help people absorb nutrients in environments where food and water are limited and disease is prevalent. In the next stage of the project, researchers will focus on links between water access and the progression of HIV, and will also investigate how improved diets from better water access can impact household income.

Smallholder irrigation a development priority in sub-Saharan Africa
A new study published today in the Proceedings of the National Academy of Sciences by FSE researchers finds smallholder irrigation has great potential to reduce hunger, raise incomes, and improve development prospects in an area of the world greatly in need of these advancements.
But even the cheapest pumps can still be prohibitively expensive without financing.
Distributed irrigation systems are those in which the water access (via pump or human power), distribution (furrow, watering can, sprinkler, drip lines, etc.), and use all occur at or near the same location.
These systems have the potential to use water more productively, improve nutritional outcomes and rural development, and narrow the income disparities that permit widespread hunger to persist despite economic advancement.
Only 4 percent of agricultural land in sub-Saharan Africa is currently irrigated.
"Success stories can be found where distributed systems are used in a cooperative setting, permitting the sharing of knowledge, risk, credit and marketing as we've seen in our solar market garden project in Benin," said lead author Jennifer Burney
Moving forward development communities and sub-Saharan African governments need a better understanding of present water resources and how they will be affected by climate change.
"Farmers need access to financial services—credit and insurance—appropriate for a range of production systems," said co-author Rosamond L. Naylor. "Investments should start at a smaller scale, with thorough project evaluation, before scaling up."
FSE continues to contribute to these evaluations and added eight new villages to our project in Benin last year.
The case for distributed irrigation as a development priority in sub-Saharan Africa
Distributed irrigation systems are those in which the water access (via pump or human power), distribution (via furrow, watering can, sprinkler, drip lines, etc.), and use all occur at or near the same location. Distributed systems are typically privately owned and managed by individuals or groups, in contrast to centralized irrigation systems, which tend to be publicly operated and involve large water extractions and distribution over significant distances for use by scores of farmers. Here we draw on a growing body of evidence on smallholder farmers, distributed irrigation systems, and land and water resource availability across sub-Saharan Africa (SSA) to show how investments in distributed smallholder irrigation technologies might be used to (i) use the water sources of SSA more productively, (ii) improve nutritional outcomes and rural development throughout SSA, and (iii) narrow the income disparities that permit widespread hunger to persist despite aggregate economic advancement.
Stuck in the Mud: Stanford’s Scholarly Farmer on the Soggy Fortunes of Midwest Growers
My wife and I are again spending the summer on our farm in Eastern Iowa. I am fourth-generation from land just a mile away, first settled by the Falcon family in 1858. My wife is also fourth-generation, from the farmstead we now own. Our land is a medium-sized corn, soybean, and cow and calf operation in the heart of a very rural Iowa county—though Starbucks is only seven miles away! Summers here provide a pleasant change from my day job, which is as Farnsworth Professor of International Agricultural Policy at Stanford University. It helps when teaching agriculture to have one’s feet in the soil. In 2013, “in the mud” is a more appropriate phrase.
My farm notes from 2012 chronicled the problems of farming during one of Eastern Iowa’s most severe droughts. Because of high temperatures and low rainfall, it was a truly miserable production year for farmers—made only mediocre financially rather than miserable—by the widespread use of crop insurance. Drought affected many states, and last year the national federal subsidies on crop insurance were nearly $15 billion, more than the total that was spent combined on all of the other farm-related programs in the federal Farm Bill.
But what a difference a year makes. We have gone from one of the very hottest and driest years on record to one of very coldest and wettest. But what a difference a year makes. We have gone from one of the very hottest and driest years on record to one of very coldest and wettest. For Iowa, it was the wettest spring ever, eclipsing the 1892 record. The riskiness of farming is something to see in real time; it is also very instructive to listen as farmers talk about coping with uncertainty. Listening to them is not very difficult if one is prepared to invest a bit of time. In most rural areas, there is typically a restaurant, diner, or some other slightly disreputable place where farmers gather for early morning coffee. For our group, it is the old limestone store in Waubeek—the limestone having been hauled by horses in 1868 from nearby quarries at Stone City, the historic home of Iowa’s most famous painter, Grant Wood. What have not changed from last year are the watery coffee, the stale cookies, and the energetic exchange of farm tales—mostly true, occasionally coarse, and sometimes more than a little embellished.
As with last year, the talk is about weather—though now the signs have all been reversed. Last spring it was dry; this spring it was wet. It rained and rained and rained. During the critical planting period of April, May and June, it rained in significant amounts in our area for 40 days. We received 21 inches in total, as compared with less than 8 inches last year. Much of it came in torrents, leading to significant erosion, runoff, and flooding. Moreover, the weather was cold. The local weather station reports that average temperatures for May and June were about 6 degrees cooler than in 2012, which is huge as those kinds of comparisons go.
Farmers have had plenty of time for morning conversations, since the fields were so wet there was not much else to do. They commiserated about a lot of things, and here are some of things I heard and learned. Virtually everyone said planting had been delayed at least three weeks beyond the first week in May, the date most think is their optimal planting time. Perhaps a quarter said that the delays were so bad that they were shifting some fields from corn to soybeans, since the latter typically do better than corn if planted in June. Everyone spoke of having fields with low spots that would simply go unplanted, or if planted, were flooded out with zero yields expected. (And everyone was checking the fine print of their crop insurance policies to determine coverage for land that could not be planted due to weather, so-called “prevented” acres.)
The temperatures were so cool that corn seeds often lay in the ground and rotted or only germinated partially. They talked about the merits of re-planting—the costly process of “tearing out” what had already been planted to replace it with new seed. The calculus of that decision is complicated, since it involves further delays in the crop cycle and, at a minimum, the cost of new seed and tractor fuel. New corn hybrids cost up to $100 per acre, depending on the special traits that have been stacked into the seeds, thus putting seed costs on par with those of nitrogen fertilizer. All farmers grow genetically modified corn, and those who initially had paid extra for the more expensive, drought-resistant seed seemed more resigned—“the cost of doing business”—than angry.
There was also great concern about fertilization this year. Agronomists have been urging farmers to put nitrogen into the ground (called side-dressing) when plants needed the nutrient, rather than prior to planting, to help prevent nitrogen losses due to runoff or into the atmosphere and groundwater. My neighbors know that nitrogen runoff is a problem, but as one put it, “this year we are screwed; because of the rain, we can’t get back into the fields with supplemental nitrogen.”
The number of rainy days was totally frustrating for livestock farmers as well, most of whom also grow alfalfa for forage. There was barely a sequence of dry days long enough to make hay. The quality of the alfalfa diminished, as it grew tall and coarse. On our farm, we actually baled hay on the 4th of July. The lateness of this first cutting will mean the loss of at least one, and possibly two, later cuttings. The latter, of course, are the most valuable in terms of quality and price per bale.
The 4th is also the traditional benchmarking date for the corn crop. Historically, corn was supposed to be “knee high by the 4th.” But with new varieties of seed and early planting dates, corn is typically shoulder high. In 2013, however, it really was knee high and looking puny and yellowish. The 4th is traditionally also the start of the season for sweet corn—the best in the world! But it too was delayed by more than two weeks. The bit of good news is that the Japanese beetles, a fierce pest in 2011 and 2012 to both soybeans and home gardens, have yet to appear.
The flooding that accompanied the rain was huge. Iowa expects to lose substantial acres of corn because of flooded fields. Almost every farmer I know was affected in some way or another. The week after we arrived from California, for example, we had two severe storm warnings and one tornado warning in the first four days. The tornado blew around us, but the latter of the storms came in torrents. With the rivers running high, and with the soils saturated, flash floods happen almost instantaneously, as we experienced first-hand. Our large permanent pasture, summer home for the red Angus cow and calf herd, contains a medium sized creek. It quickly overflowed flooding the entire pasture. The cows and calves were understandably unhappy, bawling loudly and persistently, thereby triggering a 5 am rodeo in the rain as they got moved to the barn on higher ground. (Rodeos in the rain are not fun, however glamorous and intriguing the thought may be. There is always one calf….) But it was a good thing the move was made. For later in the morning, we saw that the flood had taken out 50 yards of fence, thus opening the pasture up to the adjacent highway. And for those interested, repairing creek fences is not a whole lot of fun either.
That same storm had countywide effects as well. The Linn County Fair was to open on June 26th, and unfortunately the fair grounds sit alongside the good-sized Wapsipinicon River. The storm had pelted areas upstream and the river was rising rapidly. There was a decision to be made. National and local weather service models projected a crest of 25 feet, which would mean four feet of water in the grandstand, and a small lake where the exhibits were to be. The fair was called off, and that is a BIG decision for a rural area. It affected almost every farm family, especially the farm boys and girls who had spent literally a year preparing their 4-H and F.F.A. (Future Farmers) projects—from livestock to sewing—for the competition. Everyone then waited in gloom for the fairground to flood. But it didn’t! The fair had been canceled for naught.
The forecasters had missed the river crest, and missed badly. What was estimated at 25 feet, turned out in fact to be 14.95 feet. Everyone thought that a miss by one foot was understandable, but that a miss by ten feet was sheer incompetence! They were relieved that the flood had passed, and bore no ill will against the fair committee. But the coffee conversations the next few days were blue about government forecasters. I cringed, given my day job, when one of my neighbors said, “those weather guys are even worse than the damned economists.” And that comment then triggered a lengthy conversation about the Department of Agriculture (USDA) forecasts for the size of the new (2013) corn crop.
Despite the wetness in the Midwest, the USDA at the time was predicting a record corn harvest for 2013. Farmers, who tend to be a bit myopic and to see and think the whole world is like their county, simply didn’t believe the numbers—neither the area nor the yield forecasts. Those estimates of a big crop were helping to drive prices for the 2013 crop down to about $5 per bushel for corn, relative to the $7 per bushel farmers had received during 2012 and the early months of 2013. Several of them argued that it was a deliberate attempt by the government to drive down prices. I suggested that it wasn’t what the government thought, but what markets believed that was important. But they had a point, because the markets couldn’t figure out the estimates either, with a great deal of day-to-day variation in prices based on weather assumptions, both in the U.S. and in China.
At last the rains finally broke and there was a week of dry weather. What happened in the countryside then was nothing short of amazing. Farmers, typically with help from their spouses and extended families, worked 24/7. Tractors, with lights, comfort cabs, and sophisticated GPS systems to do virtually all of the steering, pulled 16- or even 24-row planters; they were everywhere one looked. So much planting took place in those few days that fertilizer dealers were overwhelmed by the logistics of moving sufficient quantities of starter fertilizer into the countryside. During that one week alone, 56 per cent of Iowa’s entire corn crop was planted!
These notes are being written in real time, and what this year’s harvest will bring eventually is now anyone’s guess. At a minimum, the harvest will be late, which means that an early frost could be a very serious problem. Farmers now are beginning also to worry about late-season precipitation. (My wife is convinced that we have had our rain for the season, and that from now on we will see drought.) Farmers are not an optimistic lot when it comes to forecasting weather! But at this point in the season, most of farming is waiting.
My clearest conclusions from the last two years are about risk. Farmers and farming communities face lots of it, and in almost every direction they turn. (I smile inwardly every time I am told by neighbors, “I don’t see how you can live in California with all those earthquakes!”) Modern corn-belt agriculture is complicated, capital-intensive, and uncertain. That is why federal crop insurance is already such a key element in the new Farm Bill, and likely to become even more so in the context of future climate variability and change. Finally, anyone who believes that farming is done by those who can’t do anything else, or that farms are quiet, idyllic places, ought really to spend a summer on an Iowa farm.
Bringing a green and blue revolution to Africa
Food and water security in sub-Saharan Africa remain a challenge despite the region’s abundance of arable land and untapped water resources. In FSE’s final global food policy and food security symposium, water expert John Briscoe drew upon his many years of international field experience (including a 20-year career at the World Bank) to deliver a personal assessment of the issues facing Africa and suggestions for the way forward.
Improvements in infrastructure, agricultural productivity and investment are crucial for tapping Africa’s agricultural and development potential. And middle-income countries, such as Brazil, may have the most lessons to share.
Dams and the quest for water security
“Africa’s infrastructure is lousy,” said Briscoe, an environmental engineer and director of Harvard’s Water Security Initiative. “Crumbling roads, patchy supplies of electricity, and inadequate water storage are some of Africa’s biggest impediments to growth.”
Africa has the potential to irrigate an additional 20 million hectares of land, but building that infrastructure is expensive and finding funding has become more difficult. Historically, the World Bank and wealthy countries like the United States have helped. But funding dams is now unpopular.
Meanwhile, middle-income countries - such as Brazil, India and China - are building infrastructure for water-enabled growth, and are filling the funding gap left by rich countries. Whereas the World Bank now finances about five dams, the Chinese finance over 300 dams outside of China in the developing world.
Sub-Saharan Africa has benefited from some of these projects, but still contends with an international NGO and donor community resistant to dam development.
Big is beautiful – the case of Brazil
“Africa must increase its agricultural productivity, and a romantic emphasis on small, local, organic farming is not going to get it there,” said Briscoe.
Sub-Saharan Africa’s agricultural growth rate remains very low. In some countries, yields for staple crops like maize are actually falling. A deficit in knowledge to increase agricultural productivity is part of the problem.
Briscoe shared a telling observation of a Ghanaian CEO of a multinational company: ‘Once the best and the brightest Ghanaians went into engineering. Now they become anthropologists because NGOs dominate the job market and this is the skill they want.’
Briscoe pointed to Brazil as a compelling case for greater investment in agriculture and agricultural research. Between 1985 and 2006, Brazilian agricultural production grew by 77 percent.
“Much of this growth did not come from cutting down the Amazon, but by doing things smarter than it did before,” said Briscoe. “Over the last 30 years, through financial crises and changing political parties, Brazil sustained public investment in agricultural research.”
Additionally, Brazil pioneered the use of “no-till” agriculture, now practiced by over 50 percent of its farmers. The culmination of these activities increased productivity while farming more sustainably.
An important contribution to Brazil’s productivity has been its utilization of genetically modified crops. Brazil chose not to eulogize the “small and organic” philosophy of many NGOs, but embraced new technology. Middle-income countries are currently eight of the 10 largest users of GMOs.
Brazil was also pragmatic when it came to scale. Brazilian farms are large. Thirty percent are large commercial operations producing 76 percent of the country’s output. Many environmentalists and small farmers perceived large agrobusiness as the enemy, but these large enterprises were also the grey geese laying the golden eggs for the country.
Understanding that there are no silver-bullet solutions, the Brazilian government sought innovative ways to support smaller farmers. For example, concessions for a large irrigation project in the Pontal were awarded to agribusiness operators that integrated at least 25 percent of irrigable land to small farmers as part of the company’s production chain.
Sugarcane
“Brazil’s success did not happen over night,” said Briscoe. “African countries must be patient and persistent, particularly with respect to public investment in agricultural research…and pragmatic and realistic about scale.”
Role for foreign investors
In the face of low levels of public investment in agriculture and non-existent or shallow domestic capital markets, there is a role for foreign direct investment (FDI) to play. FDI projects, such as international land deals, can help create implementation capacity by bringing capital and know-how, creating employment and developing infrastructure.
“But it is easier said than done,” said Briscoe. “Foreign investors, including the World Bank's International Finance Corporation (IFC), have struggled in sub-Saharan Africa because farming is a complex business.”
Briscoe noted a shortage of indigenous entrepreneurs, the small size of potential investments, and lack of access to markets have constrained IFC engagement and performance in sub-Saharan Africa.
While there are no shortcuts for Africa, Briscoe insisted optimism and a determination to move faster are needed. Africa must decide whether to follow the prescriptions of the advocacy community or, like Brazil, pursue an opposite strategy.
“Will Africa focus on its real problems, ‘the politics of the belly’?” asked Briscoe. “Or will it succumb again, to the western ‘politics of the mirror’?”

The water and agriculture glass in Africa is half-empty: Africa has failed to develop its massive water resources and failed to achieve agricultural growth. But the glass is half full, too, as Africa is making a start in building its needed infrastructure and in attracting managerial and knowledge assistance which can help start the needed transformation.
In engaging with this great challenge Africa has to make a choice. Will it continue to follow the path advocated by many in the aid community of the rich countries who say “the soft path”, “no dams”, “the social cart before the economic horse”, “small is beautiful” and “no GMOs”? Or will Africans follow the alternative path that brought food security to Asia and income-enhancing agricultural growth to Latin America? The latter focused on science, infrastructure, management and scale. Will, in short, Africans follow “the politics of the mirror” or the “the politics of the belly”?
