China’s commitment to agricultural development over the last thirty years has dramatically transformed the country’s economy. Rural income per capita has risen an astounding 20 times after 30 prior years of stagnation. Its poverty rate (US$1.25/day) has dropped from 40 percent to less than five, and 350 million rural people between the ages of 18-65 are now working in the industrial or service sector, enjoying rising wages and new economic opportunities.

This rapid transformation is largely the result of three key agricultural policy decisions: putting land in the hands of farmers, market deregulation, and major public investment in the agricultural sector. Although China must now contend with extreme inequality, high levels of pollution, and an aging farming sector there are still lessons to draw from China’s experience that could hasten the transformation of other developing countries.

China expert and agricultural economist Scott Rozelle broke these lessons down at FSE’s fourteenth Global Food Policy and Food Security Symposium Series last week, opening with an underlying theme of the series.

“Growth and development starts with agriculture,” said Rozelle. “Agriculture provides the basis for sound, sustained economic growth needed to build housing, invest in education for kids, start self-employed enterprises, and finance moves off the farm.”

To prove this point he referenced China’s ‘lost decades’ (1950s-1970s) when 80 percent of the population lived in the rural sector and relied on communal, subsistence agriculture. Poor land rights, weak incentives, incomplete markets and inappropriate investments left the average rural farmer poorer at the end of 70s than they were in the 50s with almost no off-farm employment growth.

So what changed? Incentives, market deregulation and strategic investments by the state were key.

Creating the right incentives

In 1978 the Chinese government broke the communes down into small “family farms” such that every rural resident was allocated a small parcel of land. A family of five farmed an area the size of a football field. While they did not own nor could sell the land, they had the right to choose what crops and inputs they used and the right to the income generated from their land.

“Incentives are important, and can be enough in the short run,” said Rozelle. “Hard work led to money in the pockets of farmers and China was off.”

“Every two and half years China added another California in term of agriculture,” said Rozelle.

Between 1979 and 1985 productivity for wheat, maize, and rice went up 50 percent using the same amount of labor, land and inputs. Agriculture across the spectrum has grown at an astounding rate of 5 percent since 1988 (about four times the population growth rate). Livestock and fisheries have grown even faster – accounting for most of the output of the agricultural sector by 2005.

Income growth from farming enabled family members to begin to seek work off the farm. Between 1980 and 2011, off-farm work increased 71 percent with more than 90 percent of households reporting that at least one family member worked off the farm.

Increasing efficiency through liberalization and investment

Another key policy decision was China’s commitment to market liberalization and investment in public goods.

“Markets can be an effective, pro-poor tool of development,” said Rozelle. “A remarkable partnership is formed when you let farmers do production and government do infrastructure…let markets guide decisions.”

The government dismantled state-owned grain trading companies and deregulated trading rules. Prices were set once a week the same day across China to better integrate markets, and eventually prices for major crops closely mirrored those of world prices. Villages began specializing in crops and livestock and incomes of the poor increased. By not providing government input subsidies (e.g, pesticides, fertilizers), traders were incentivized to participate in the market.

“Giving land to farmers and letting the private sector emerge is an easy thing for governments, even without a lot of money, to do,” said Rozelle.

The government provided more indirect market support by publicly investing in better roads, communications, and surface water irrigation. Groundwater was left to the private sector. There were no water or pumping fees nor subsidies for electricity, keeping it completely deregulated. As a result, 50 percent of cultivated land in China is irrigated, compared to 10 percent in the US and only four percent in sub-Saharan Africa.

Finally, China has invested heavily in agricultural research and development (R&D). One percent of China’s agricultural GDP is now invested in agricultural R&D while US investment has fallen over time. US$2 billion alone goes to investments in Chinese biotechnology.

Despite major investment, China only has one major success story to show for so far. The introduction of Bt cotton led to a significant drop in pesticide use (with important health benefits for farmers), and drop in labor and seed price; resulting in a huge 30 percent increase in net income.

“GM technology benefits exist but big policy decisions still need to be made in the face of much resistance both in China and elsewhere in the world on its application,” said Rozelle.

Status of China’s economy

China has largely solved the country’s macro-nutrient food security problem at the household level (>3000 Kcal/day/person) and millions have been lifted out of poverty. Practically all 16-25 years old are now working off the farm.

“This is a real transformation, and one that could not have happened without a major investment in agriculture,” said Rozelle.

While China’s agricultural accomplishments have been major, Rozelle recognizes the system is far from perfect. For starters, there are serious food safety concerns due to lack of traceability. An astounding 98 percent of Beijing consumers think their food is tainted, said Rozelle.

Water is being pumped like crazy and farmers are aging. The younger generation is neither willing nor interested in following in their parents’ farming footsteps. To make up for a labor deficit farmers are applying huge amounts of fertilizer on their land with serious environmental consequences. As a result of changing demographics and an increasing demand for meat, fish, fruits and vegetables, China is likely to be a net importer of food in the long run.

China also faces major urban and rural inequality issues. Even though wages have risen, inequality has not fallen, largely a result of China’s decision not to privatize rural land.

“Rural people have no assets on which to build wealth while urban people were given assets in the form of housing,” said Rozelle. “Housing prices in major cities in China now rival those in the Bay Area!”

The Chinese government fears losing control of the land, but this comes at a price of less individual incentive to invest and inability to build larger farmers. As agricultural growth slows, Rozelle worries high levels of inequality could lead to instability.

Adding fuel to the fire, investment in rural health, nutrition, and education remains far from sufficient. Only 40 percent of the rural poor go to high school resulting in 200 million people who can barely read or write.

“What’s going to happen in 20 years when low skill manufacturing jobs move to other countries?” asked Rozelle. “The rural, uneducated poor are going to become unemployable.”

China’s record leaves room for improvement, but presents a strong case for supporting smallholder agriculture. For those countries emerging out of their own lost decades, smallholder agriculture should remain a primary focus of investment and development.

Paragraphs

The lost decades for China in the 1950s, 1960s and 1970s look remarkably like the lost decades of Africa in the 1980s and 1990s. Poor land rights, weak incentives, incomplete markets and inappropriate investment portfolios. However, China burst out of its stagnation in the 1980s and has enjoyed three decades of remarkable growth. In this paper we examine the record of the development of China’s food economy and identify the policies that helped generate the growth and transformation of agriculture. Incentives, markets and strategic investments by the state were key. Equally important, however, is what the state did not do. Policies that worked and those that failed (or those that were ignored) are addressed. Most importantly, we try to take an objective, nuanced look at the lessons that might be learned and those that are not relevant for Africa. Many parts of Africa have experienced positive growth during the past decade. We examine if there are any lessons that might be helpful in turning ten positive years into several more decades of transformation.

Households depend upon food prices, incomes, and disease burdens that impact the ability to use consumed food. Climate change and extreme temperatures impact all of these factors. In this talk, David Lobell focuses on the impact of heat in growing regions that are important for food prices. He reviews recent research on heat impacts and discusses whether crop yields are becoming more or less sensitive to heat.

According to a new study by FSE's David Lobell, satellite data can play a critical role in understanding yield gaps and meeting future crop demand. Lobell's review appeared in a special issue in Field Crops Research dedicated to crop yield gap analysis.

To date, satellite data have played a relatively small role in understanding the magnitude and causes of yield gaps in most regions. However, the few examples that exist indicate that remote sensing can help to overcome some of the inherent spatial and temporal scaling issues associated with field-based approaches.

"Yield gap profiles, based on multiple years of satellite data, provide a useful measure of how persistent yield-controlling factors are through time," writes Lobell in his review. "Although the cost or availability of satellite data with sufficient spatial resolution to discriminate agricultural fields was an obstacle in the past, this barrier is rapidly diminishing."

Improved algorithms to pre-process remote sensing data and estimate yields, and the increased availability of new, large geospatial datasets on soils, management, and weather should also benefit future efforts in this area.

"Improved knowledge of yield gaps will play a critical role in meeting future crop demands at affordable prices and with minimal environmental impacts," concludes Lobell. "The use of satellite data can accelerate the pace of discovery, and as such it represents an important area for future work."

Africa owns 60% of the world’s uncultivated land suited for crop production, but accounts for 30% of the world’s malnourished and only 3% of global agricultural exports. If there is one thing global agricultural policy experts Paul Collier and Derek Byerlee can agree on, it’s that Africa’s food system is struggling.Their different views on the causes and investment solutions to put Africa on a more prosperous and food secure path made for a provocative discussion at a symposium hosted last week by Stanford University’s Center on Food Security and the Environment.

Collier, a distinguished economist and author of the award-winning book “The Bottom Billion”, was direct in his opening remarks.

“Smallholder agriculture has been a persistent productivity disaster for Africa,” said Collier. “Despite a huge land area to population ratio and higher proportion of its labor force engaged in food production, Africa is still not able to feed itself. The smallholder business model of the last 50 years is fundamentally flawed…maybe it is time for a Plan B.”

African agricultural productivity remains astoundingly low and stagnant at about $500 per person per year. His solution: debunk the ‘myth of the efficient peasant’ and rural romanticism and support commercial agriculture and urban growth.

Commercial agriculture reaps economies of scale that provide advantages often beyond reach for smallholder farmers yet are critical to agricultural production in Africa—risk finance, liquidity, technology, logistics, and knowledge of markets. Collier points to the success of Brazil and Thailand—two emerging economies that differ in scale of commercial organization, but have become major agricultural exporting countries.

Byerlee, a renowned economist and director of the 2008 World Development Report, agreed with Collier that commercial agriculture is likely Africa’s future, but that market-oriented smallholder farmers will play the lead role.

“We have much to learn from emerging business models,” said Byerlee. “Smallholders and agribusiness have complementary assets that can contribute to commercial agriculture, and states and investors must help facilitate smallholder inclusion in these models.”

Byerlee noted that the choice between small-scale or large-scale production models depend on transaction costs and type of commodity, and are context specific. Small- to medium scale production is best suited to most types of products in Africa especially food staples and many labor intensive products (e.g, diary). This follows the example of Thailand that not only has succeeded in food production but alone exports more than the value of all sub-Saharan Africa. Value chains that require stronger coordination with processing and shipping (e.g., sugar and palm oil), demand market standards (e.g, export horticulture) or are taking pioneering risks (e.g., new crops in new areas) may be better suited for large-scale production. Benefits may still be large if they create good jobs—a major challenge for Africa’s future.

Where to invest in Africa’s future?

"Young Africans are voting with their feet in droves to leave smallholder agriculture because it is impoverishing and boring, “ said Collier. “The economic tragedy for Africa is that cities haven’t been the engines of economic opportunity and wage employment.”

Collier argued investments in cities over agriculture are needed to prepare for an urban future and must be done quickly due to one dangerous fact—climate change.

“Climate change is the train coming down the tracks and it is already happening in Africa,” warned Collier. “The continuing deterioration of African agriculture is already set in stone. The last 50 years of carbon emissions are going to continue to devastate Africa’s climate over the next 50 years.”

Collier fears climate change will shift Africa’s competitive advantage in agriculture to Northern Eurasia and North America. Therefore, limited investment dollars must shift to cities which are more climate resilient. Byerlee disagrees.

“There is overwhelming and convincing evidence that agricultural growth is important for poverty reduction and food security,” said Byerlee. “Look at the Green Revolution in Asia and the institutional reforms in China in the early 1980s.”

The 2008 World Development Report also found GDP growth from agriculture benefits the income of the poor two to four times more than GDP growth from non-agriculture. So why isn’t this working for sub-Saharan Africa?

Byerlee points to Africa’s history of poor macroeconomic policies that have disadvantaged African farmers. Smallholder farmers have traditionally been taxed at high levels (as much as 50 percent 20 years ago before liberalization programs started kicking in). Rates have come down dramatically to 15-20 percent, but are still significantly higher than other countries.

“African states must level the playing field,” said Byerlee.

Government investment in public goods at four percent of agricultural GDP still lags behind that enjoyed by most other countries. That is less than half of what has been spent in Asia over the last couple of decades where investment in core public goods, R&D, rural roads, and irrigation have really made a difference.

Access to land and finance must also improve to support the growth of smallholder agribusiness. This especially includes secure, low cost, and transferrable land rights to allow efficient smallholders to expand.

Greater investment is also needed in technology and information. Research and development in Africa have been traditionally underfunded and understaffed. Despite involvement of agricultural research groups such as CGIAR over the last 40 years, only 35 percent of food crop area is planted to improved varieties. Smallholder farmers also often lack business development skills and access to primary education – a critical constraint to growth.

Reasons for optimism

Many of these macropolicies are slowing changing, and that makes Collier and Byerlee hopeful.

“After four decades in sub-Saharan Africa I feel optimistic about Africa’s food systems and future,” said Byerlee. “I see exciting opportunities in terms of market growth, private interest, and improved policies.”

Yields in Africa are low, but there is room for significant improvement. The continent is home to potentially 240 million hectares of uncultivated land and less then 20 percent of irrigation potential has been tapped.

African agricultural systems are transforming rapidly in response to rising rates of income growth, urbanization, and shifts in demand for high value and processed food, and feed for livestock. Higher food prices are incentivizing farmers to enter the market and increasing farmer income. Regional markets now accounting for only 5-10% of trade have much potential to expand, and Byerlee projects the value of African urban food markets to quadruple over the next 20 years.

Renewed investment in Africa is another reason for optimism. After decades of declining support donor agencies are refocusing their efforts on supporting agricultural development in Africa. Private sector investment, ranging from local to foreign investors, is also increasing. Collier spoke of the value pioneer commercial investors are bringing to unused and underutilized, but arable lands in Africa. These larger investors are better able to internalize the benefits of infrastructure supply while creating jobs and opening new markets.

The spur in foreign investment has drawn some fire from opponents worried about ‘land grabbing’. Collier and Byerlee both pointed out the need to differentiate between commercial investors and land speculators. The latter are being scrutinized, and for good reason.

Land speculators are leasing huge tracts of land over long time horizons and banking on the land’s option value if there is a big spike in food prices. This takes potentially arable land out of near-term production and out of the hands of local communities. Byerlee suggests governments impose controls on how rapidly the land is developed as one way of managing this problem.

What will a successful African food system look like in 2050?

"African peasantry as we know it today will not be preserved," projects Collier.

“If commercialization is successful most Africans will live in big coastal cities like the US and Europe,” said Collier. “Most of the remaining rural population will move to the hinterland of the big cities, because profitable agriculture will be selling into the big cities from close vicinity."

He envisions a mixture of different types of commercial agriculture ranging from consolidated family farms as is the norm in the US to large-scale enterprises as seen Brazil, but agriculture will not employ a lot of people. He sees an opportunity for commercial agriculture to piggyback off the infrastructure put in place by extractive natural resource companies.

Byerlee foresees Africa headed down a path similar to Thailand where a more egalitarian, smallholder commercial farmer model dominates (2-5 hectares). Large-scale farming has a legacy of failure in Africa, he said. He sees better prospects for large-scale irrigated rice and perhaps oil palm. Oil palm was actually an African crop prior to moving primarily to Malaysia and Indonesia. The value of South East Asian exports of palm oil is now greater than all agricultural exports from sub-Saharan Africa. In fact, Africa now imports $3.5 billion in palm oil.

“With billions of dollars at stake, big Asian companies are investing in Africa with the potential to create millions of jobs,” said Byerlee. “Oil palm could be a really big opportunity to transform African agriculture in the humid tropics, but state support is needed to facilitate inclusion of smallholders and safeguard social and environmental standards."

Africa has the natural resources to become a major player in the global agricultural export market and to bring down its alarmingly high malnutrition and poverty rates. What’s needed now is the political will, guidance, and investment to make that happen.

Paragraphs

Rapid population growth, urbanization and rising incomes will present an unprecedented opportunity for growth of commercial agriculture and agribusiness in coming years. The value of food consumed in urban areas is set to expand by four times to 2030, but given evidence of a continuing decline in competitiveness much of this could be sourced from imports even in countries with an apparent comparative advantage in agriculture. At the same time, the number of youth entering the labor force will rise to 25 million annually by 2025 putting tremendous pressure on job creation, especially through agriculture. Rising investments in large-scale farming seen in recent years may contribute to increased food supply (although this is highly uncertain given the track record) but some investment, especially in mechanized grain farms, provide few jobs. Even so there is a dire need for increased investment in the sector, both public and private, if it is to realize its potential for growth and poverty reduction.

This paper lays out a number of models of inclusive agribusiness growth, grouped into three categories (i) institutional arrangements for improving productivity of smallholders operating in spot markets, (ii) various types of contract farming arrangements, and (iii) large-scale farms that generate jobs and/or include community equity shares. The institutional and policy context as well as commodity characteristics that favor these models are discussed within a simple transactions cost framework. Examples of apparent successes with each of these models are provided, many based on direct interviews and case studies of innovative firms.

The final section discusses cross-cutting policy priorities to enable the growth of commercial agriculture and agribusiness. These include continuing reforms to liberalize product and input markets, access to technology and skills, stimulating financial and risk markets, securing land rights, and investment in infrastructure through public-private partnerships. Priorities differ by value chain and implementation presents challenges of delicately balancing state intervention and leadership with private initiative. These challenges are illustrated through examples from Africa as well as emerging countries of Asia and Africa.
