“Do we have to accept deforestation to feed the world?”

That was one of the provocative questions that Stanford Woods Institute Senior Fellow and land use expert Eric Lambin posed during a recent presentation of research with far-reaching implications for policymakers, businesses and consumers. Among the findings Lambin discussed with Stanford students and faculty during a Stanford Department of Environmental Earth System Science seminar: There is much less potentially available cropland (PAC) globally than previous estimates have suggested. Perhaps surprisingly, however, we don’t need to clear more land, including forests, to plant hunger-alleviating crops, Lambin said.

Previous PAC estimates by international organizations such as the World Bank have been consistently too high, according to Lambin giving decision-makers “carte blanche” to approve a variety of uses for large tracts of land.

By 2030, the additional land worldwide that will be needed for urban expansion, tree plantations and biofuel crops will equal the additional land that will likely be devoted to food crops, according to Lambin. This rapid transformation of the face of the planet makes it essential to get a handle on realistic PAC estimates. To do so, Lambin took a “bottom-up approach” that incorporated factors such as soil quality, land use restrictions, labor availability and occupation by smallholders. Lambin also considered trade-offs such as the carbon stocks lost and natural habitat destroyed by land conversion.

Lambin’s resulting PAC estimates in regions ranging from Argentina to Russia are, on average, only a third of other generally accepted estimates. Along the way, Lambin discovered some surprises. For example, what initially looked like good news – the fact that some countries have gone from net deforestation to net reforestation in recent years – turned out to be less hopeful. Lambin found that most countries in the developed and developing worlds that have stopped cutting down their forests have increased their imports of timber and wood products, often from tropical countries. This “outsourcing of deforestation” is one of several troubling global land trends.

On the other hand, Lambin pointed out that production of crops essential to alleviating hunger have increased in recent years, but their overall land use has not, due to more efficient and intensive agricultural methods. This net gain contradicts assertions that more land, including forests, needs to be cleared for farming in order to alleviate hunger, he said.

The real culprit for such land conversion, according to Lambin, is growing adoption of a Western diet heavy with meat, sugar and vegetable oils. Deforestation for agriculture is often driven by multinational companies that cultivate in tropical regions to export fatty and oily food products to urban markets in rich countries and emerging economies. These companies control a majority of global food supply chains and, in turn, local land use decisions. “Globalization has reshaped land governance,” Lambin said.

Globalization is not a bogeyman, though. In fact, Lambin said, it can be an engine for progress on these issues by allowing for new forms of market-based governance that effectively promote sustainable land use. Market mechanisms such as eco-certification labels and nongovernmental campaigns can promote and incentivize responsible land use, he noted, pointing to coffee farmers he studied with School of Earth Sciences Research Associate Ximena Rueda. The farmers increased tree cover on their plantations with the extra profit they reaped from eco-certified beans.

Seeds of Sustainability tackles a central challenge of sustainable development: agricultural modernization. It is cutting edge not because the issue itself is new, but rather the level of integration the authors attempted and the innovative process they used. The volume summarizes the findings and reflects on the process of a highly interdisciplinary team of researchers, integrating perspectives from: biogeochemistry, atmospheric sciences, land-use change, institutions, agronomy, economics, and knowledge systems. The foundation of the work is rigorous, grounding its findings in multiple peer reviewed publications, while not hesitating to point out gaps or unresolved issues. Seeds of Sustainability includes an in depth historical analysis, which captures issues of path dependence. It demonstrates both originality and critical reflectiveness in its efforts to engage practitioners in the conceptualization and execution of its research, and the implementation of its findings. And almost uniquely in our collective experience, it speaks seriously, frankly, and insightfully to the challenges of institutionalizing the sort of work it reports on.

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.

“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’?”

Join us for our final Global Food Policy and Food Security symposium Thursday, May 23. John Briscoe, Gordon McKay Professor of the Practice of Environmental Engineering at Harvard University will lead a lecture on Water and agriculture in a changing Africa: What might be done?. FSE fellow Jennifer Burney will provide commentary.

President Barack Obama’s 2014 budget proposal promises significant food aid reform that will enable the United States to feed about 4 million more people without a significant increase of the current $1.8 billion spent on feeding the world's most hungry. Since the food aid program's inception in 1954, the U.S. has helped feed more than 1 billion people in more than 150 countries, and remains the largest provider of international food aid.

The intention of the reform is to make food aid more efficient, cost effective, and flexible. It aims to use local and regional markets to lower the cost of food and speed its delivery, and calls for the use of cash transfers and electronic food vouchers.

The proposed reforms would also end monetization—the sale of U.S. food abroad to be sold by local NGOs for cash. This practice has been criticized for hurting vulnerable communities by depriving local farmers of the incentives and opportunities to develop their own livelihoods. Several studies, including one by the Government Accountability Office, found monetization to be costly and inefficient—an average of 25 cents per taxpayer dollar spent on food aid is lost.

Barry Riley, a food aid expert and visiting fellow at the Center on Food Security and the Environment, discusses his perspective on the importance of these new reforms, their chances of passage, and the country's current role in international food aid.

Why is local procurement such an important addition to food aid reform?

An increase of funding for local and regional procurement is the most important programmatic element of the proposed reforms. It would help managers working in food security-related development programs to determine for each emergency what commodities are most appropriate and where they can be procured most quickly and inexpensively. Some studies have shown local and regional procurement of food and other cash-based programs can get food to people in critical need 11 to 15 weeks faster at a savings of 25-50 percent. Equally important, local procurement is less likely to disrupt local economic conditions, but rather promote self-sufficiency by increasing demand (often for preferred local staples) and incomes of local producers. The move to 45 percent local (and 55 percent tied) procurement is a BIG step, and one to face strong opposition from American commodity interests and U.S.-flag shippers. 

How difficult is it to ensure vouchers and electronic cash transfers are getting into the hands of people that really need the aid?

Vouchers (and similar urban coupon shops) have been used many times over the past decades as a food transfer mechanism (also sometimes used in food for work programs) enabling the recipient to trade the voucher(s) for foodstuffs when it is most convenient or when they are most needed. Electronic vouchers are new, and how well they work depends on local situations. In places like urban Latin America, Africa and India, it probably could be made to work quite well; the technology is evolving quickly that would enable this sort of transfer mechanism.  

Rural Ethiopia, Burkina Faso, Central African Republic, Malawi – probably not so well. I’m admittedly skeptical that electronic transfers of purchasing power to remote areas would be sufficient in most cases to motivate traders to move food to these hungry areas. Their risks are extremely high and, in my experience in Africa, traders will only deliver food to remote rural areas (inevitably over very bad roads) if they can command prices considerably higher than costs plus a high risk premium.

Why aren’t international food aid organizations more in favor of direct dollar support for local operating costs?

There is (and has long been) opposition among many of the NGOs to the President’s proposal to replace “monetization” with a promise of on-going direct dollar support for the local operating costs of NGO food security-related projects. They believe it will continue to be easier to get Congress to approve money to buy American food commodities to ship overseas than to get approval for dollars to ship overseas, particularly in light of tightening budgets. These NGOs have tended, over the years, to receive a sympathetic ear from Congress.

The proposal shifts oversight of the food aid program from the Agriculture Committees within the U.S. Department of Agriculture (USDA) to the Foreign Affairs/Relations Committees of the State Department’s U.S. Agency for International Development (USAID). What is the likelihood of Congress approving this transfer?

The chance of that happening, in this of all Congresses, is about the same as winning the Power Ball Lottery. Crusty committee chair-people are extremely sensitive to reductions in their empires and the agriculture committees – especially in the Senate – are powerful committees. On top of that, there are so many elements in the overall 2014 federal budget creating heartburn on the Hill that food aid considerations are far, far, far down the line. The best the President is likely to get in the present divided Congress are hearings and a continuing resolution of some sort.

What did you wish to see in the food aid reform proposal that was not addressed in this budget?

Change, if it ever comes, will likely be incremental and halting. I’ll be happy to see any step, however small, in the right direction. The total end of tied procurement would be at the top of my wish list. Even more important, perhaps, iron-clad, multi-year commitments of funding to food security programs intended to overcome long-term institutional impediments to achieving enduring food security in low income food deficit situations…and sticking with such commitments for 15 years.

What role does food aid play in advancing American foreign policy goals?

Most importantly, by being the single largest source of food commodities to the World Food Program in confronting disaster and emergency situations. Food support to American NGOs has been under-evaluated over the past 40 years. I’ll be talking about this later in the book I am writing, but these small projects were all that kept agricultural development (and early food security efforts) going in many small countries during the “dark decades” when international finance institutions and bilateral donors were not financing agricultural development. There are valuable on-the-ground lessons in that NGO food-assisted experience still waiting to be assessed.

Let me add, given what we know about the onset of serious climate change in the decades to come, the need to supply large amounts of food to populations suffering severe food deprivation will probably grow in the future. Where will the food come from and who will pay for those future transfers?

While the U.S. remains the largest provider of food aid, what can the EU and Canada teach the U.S. about food aid policy?

Donors hate to think that other donors have something to teach them. But, of course, they always do. The Canadian and European experience with food aid is best summed up in the way their objective has come to be restated over the past 15 or so years: not “food aid” but “aid for food.” The purpose of assistance intended to improve food security is to improve either, or both, availability and access over the long term (leave nutrition aside for a moment).

European and Canadian assistance can be much more flexible in choosing the instruments – food, cash, technical assistance, training, institutional strengthening, public policy, public-private cooperation, etc. – required to achieve a realistic food security goal which I would describe as pretty good assurance that most people can get their hands on the food they need most of the time. Commodity food aid, in some form – or the promise of its ready availability when needed – will probably need to be part of the total array of inputs required for the several years needed in particular food insecure countries to achieve that “pretty good assurance.” Europe and Canada are closer to understanding this and have become appropriately flexible in concerting resources to get it done. That’s the lesson.

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.
