Preface
Renewable Agriculture and Food Systems is a multidisciplinary
journal which focuses on the science that
underpins economically environmentally and socially
sustainable approaches to agriculture and food production.
The journal publishes original research and review articles
on the economic, ecological and environmental impacts
of agriculture; the effective use of renewable resources
and biodiversity in agro-ecosystems; and the technological
and sociological implications of sustainable food systems.
It also contains an open discussion Forum, which
presents lively discussions on new and provocative
topics. However, the opinions of the Forum and responses
are solely those of the authors and do not necessarily reflect
the opinions of Renewable Agriculture and Food Systems
or Cambridge University Press.

Can organic agriculture feed the world?
Catherine Badgley and Ivette Perfecto
Forum
The prospect that organic agriculture has the potential to
feed the world is welcome news in light of the contradictions
of modern agriculture1. These include the massive
productivity of green-revolution agriculture yet the stubborn
persistence of hunger and malnutrition, the loss of
small farms even though they are more productive and
contribute more to local economies than do large farms2,
and the pervasive environmental destruction by agricultural
biocides and synthetic fertilizers even as more and more
ecological services of agricultural landscapes are being
recognized3. Organic agriculture per se cannot resolve all
of these contradictions, but its potential to provide enough
food to feed the entire world opens the door to the creation
of a new kind of food system based on agroecological
production principles. We (Badgley et al. in this issue) have
demonstrated two critical points. The first is that the
relative yields of organic versus non-organic methods
(green-revolution methods in the developed world, lowintensive
methods in the developing world) suffice to
provide enough calories to support the whole human
population eating as it does today. This conclusion is based
on a global dataset of 293 yield ratios for plant and animal
production. The second point concerns nitrogen fertility.
Data from 77 published studies suggest that nitrogen-fixing
legumes used as green manures can provide enough
biologically fixed nitrogen to replace the entire amount of
synthetic nitrogen fertilizer currently in use. Thus, the
principal arguments from critics of organic agriculture are
invalid. These results are controversial, partly from
prejudice and vested interests in the current agricultural
system and partly from disputed aspects of the analysis.
While this study claims that organic yields and nitrogen
fertility methods could feed the world, it does not forecast
yields for any particular crop or region, nor does it claim
that a global organic food system would necessarily
increase food security anywhere. Food security depends
on policies and prices as much as on yields.
Our study is not the only one to reach this conclusion.
In 1990, Stanhill4 came to a similar conclusion about
organic production based on a compilation of data from
North America and Europe (his average yield ratio was the
same as ours for the developed world). More recently,
Halberg et al.5 modeled scenarios of conversion to organic
agriculture in Europe, North America and sub-Saharan
Africa, using a globalized market model. They concluded
that large-scale conversion to organic agriculture would
not severely diminish either the global food supply or
food security in developing regions. They noted that food
policies favoring local food availability, rather than export
crops, would enhance the impact of conversion to organic
farming and increase food security in sub-Saharan Africa.
Reviewers raised issues that merit dialogue beyond the
context of the article. The first issue concerns the
differences in crop-rotation patterns between organic and
conventional grain agriculture. The second concerns the
reliability of different kinds of sources (i.e. peer-reviewed
versus gray literature) for agronomic data.
Rotation effect. Organic grain production frequently
uses a different rotation cycle than conventional production.
This difference complicates the comparison of yields
Renewable Agriculture and Food Systems: 22(2); 80-85 doi:10.1017/
S1742170507001871
# 2007 Cambridge University Press
between organic and conventional systems without some
kind of time adjustment for grain that must be grown in a
longer rotation cycle by organic methods. Corn, wheat
and rice, the world's staple grains, are grown in approximately
equal quantities (in megagrams) on a global
basis6,7. In the US, corn and wheat are usually grown in
rotation8. Corn is typically grown in a longer rotation
under organic than conventional methods. For wheat, it is
not clear that organic and conventional rotations differ in
length. Most rice is grown in irrigated fields so tailored to
rice production that other plant crops are not usually
included (although green manures and animals can be
included); organic and conventional methods for rice do
not require different rotations.
Thus, corn is the main crop for which the rotation effect
is an issue. A survey of corn/other crop rotations from the
sources of yield data cited in Badgley et al.1 (this issue)
reveals that conventional corn was grown 25-60% of the
time in rotations of 2-6 years, and organic corn was grown
25-50% of the time in rotations of 2-4 years. For the sake
of a quantitative example, we can determine the yield
adjustment for two widely used rotations of corn-a 2-year
rotation of corn-soybeans under conventional management
and a 3-year rotation of corn-soybeans-wheat + cover crop
under organic management. All other things being equal,
the organic system would produce only 67% as much
corn as the 2-year conventional system would. If we
multiply all of the individual yield ratios for corn in our
dataset for the developed world by 0.67 and then
recalculate the average yield ratio for grains, the result is
0.84 instead of 0.93. The reduction in caloric output from
the lower average yield ratio for grains in the developed
world results in a change from 2641 to 2523 total kcal
person - 1day - 1 in Model 1 (based on yield ratios from
developed countries) and from 4381 to 4358 total kcal
person - 1day - 1 in Model 2 (based on yield ratios from
developed and developing countries). Even with this timeadjusted
correction for corn, both models generate enough
calories (i.e. 2500 kcal person - 1 day - 1) to feed the
current population. These calculations are conservative
since many conventional rotations feature corn less than
50% of the time. Organic rotations are capable of sustained
production of grains rotated with other crops, as demonstrated
by the Rodale Farm Systems Trial9. A more
thorough evaluation of rotation effects requires quantitative
comparison of the plot-to-plot yield differences between
organic and conventional production and the rate of change
in both organic and conventional production methods as a
function of the rotation sequence.
Thus, the necessity for different rotation schedules
would decrease the production of corn. But since overproduction
of corn has depressed the price of corn for
many years, this change could actually benefit farmers
economically.
Gray literature. A reviewer raised the concern that
our quantitative results were suspect because a number of
our yield ratios come from the gray literature. Actually,
74% of the studies included in our analysis are from
peer-reviewed journals. For a study of this sort, which
makes a global-scale analysis, it is important to include
as many studies as possible from as many regions as possible.
We included studies of three kinds: controlled
experiments of two or more management methods,
paired-farm comparisons in regions with the same soils
and climate and comparisons on the same farm before
and after a change in management practices. All three
kinds of studies could be found in both peer-reviewed
and gray-literature sources. It is worth noting that some
gray-literature sources are quite reliable, such as the technical
reports of respected agricultural experiment stations
(the Henry Wallace Experiment Station, Maryland; Kellogg
Biological Station's Long-Term Ecological Research
Site, Michigan; the Organic Farming Research Foundation,
California). Three published works that we consulted
for data also cited a mixture of peer-reviewed
publications, gray literature and personal communications.
Stanhill's4 compilation is largely supportive of organic
farming, while McDonald et al.10 (which focuses just on
the system of rice intensification) was skeptical. The third
source was the book by Lampkin and Padel11, which cites
a similar range of sources for yield information. The
point is that our compilation is not unusual in the kinds
of sources used for analysis.
The most problematic source from the reviewer's
standpoint was the report by Pretty and Hine12 based on
survey data from 52 developing countries. Yields were
compared before and after farmers adopted specific
agroecological practices. An analysis based on data from
this report was subsequently published in Agriculture,
Ecosystems and Environment13. The main reason for
including many of the quantitative comparisons in this
report is that relatively few published studies are available
from farms in the developing world. In order to evaluate
whether the survey data biased our results for the
developing world, we performed a significance test on the
survey data compared to data from experiments and paired
farms. The test failed to reject the null hypothesis that the
means in yield ratios do not differ significantly. (This test is
explained in detail in Appendix 1 of Badgley et al.1.) We
concluded that the use of survey data from the report of
Pretty and Hine12 did not unduly bias our results for the
developing world. We note, however, the need for more
quantitative, experimental comparisons in developing
countries.
One controversial management practice is the system of
rice intensification (SRI) in developing countries. Its
proponents claim that it boosts yields substantially, while
its critics argue that best-management conventional practices
perform just as well. A reviewer commented that our
cited publications on SRI did not provide the minimum
information about soil and environmental conditions for the
sites where the studies were performed. This criticism
applied to some of the studies cited on both sides of the
debate. We tried to avoid bias by using data from both
Forum 81
proponents and critics in the debate. Furthermore, global
estimates by definition involve generalities. Detailed
information about soils, climatic conditions and specific
management practices was not given for all the studies,
regardless of publication source. In principle, these
unmeasured variables would favor yields in the conventional
system in some instances, while in others they would
favor the organic system. There is no reason to think that
the lack of information about these variables would bias our
study in any particular direction.
In general, we recognize that the high yield ratios from
developing countries likely result from the fact that many
existing farming practices do not involve optimal amounts
of synthetic fertilizer, and may not be managed optimally in
numerous other ways. The adoption of organic methods in
these settings is a huge improvement. However, our aim is
not to demonstrate the superiority of organic farming over
conventional agriculture. Our aim is simply to investigate
whether organic agriculture can produce enough food to
feed the world's population-ours is a sufficiency argument.
It is appropriate to use yields from suboptimal
existing systems in developing countries, because these
systems are representative of much of the developing world
and most of the world's farmers.
Going forward. Readers of this journal are well aware
of the achievements of alternative agricultural systems
both agronomically and economically. These achievements
would multiply with additional research on locally
suitable cropping systems, fertility methods and pest management
for different agricultural regions. Changes in
agricultural policy are essential and could foster changes
in farming and marketing practices within a few years.
As an example, the Cuban food system underwent massive
reorganization of farming and marketing methods
after the fall of the Soviet Union in 199014. After a few
years of crisis, exacerbated by the US economic blockade,
Cuba now has one of the most progressive food systems
in the world. A global food system based on agroecological
principles is possible and there are urgent reasons to
move in this direction.

Editorial response by Kenneth Cassman: can organic agriculture feed
the
world-science to the rescue?
During the past 30 years there has been a steady decrease in
funding allocated to agricultural research in both developed
and developing countries because of the widespread view
that food insecurity is primarily caused by poverty and a
lack of purchasing power rather than the inability to
produce enough food1. However, these views are being
challenged by three global mega-trends: (1) a steady
decrease in arable land area suitable for intensive food
crop production as a result of farmland conversion to urban,
industrial and recreational uses, (2) a steady reduction in
the relative rate of yield gain for the major cereal crops-
yield gains that are falling below the projected rate of
increase in cereal demand2, and (3) a recent acceleration in
the expansion of biofuel production from cereal, sugar and
oilseed crops that will divert significant amounts of these
crops from the human food supply3.
Given these trends, the question of whether organic
agriculture can meet current and future food demand at
national and global levels is serious business-especially if
the answer influences funding priorities for agricultural
research4,5. Unfortunately, the paper by Badgley et al.6 and
the associated forum paper by Badgley and Perfecto, both
in this issue of RAFS (Vol. 22, No. 2), do not answer this
question because their analyses do not meet the minimum
scientific requirements for comparing food production
capacity in different crop production systems.
Scientific progress depends on published research in
peer-reviewed journals-journals that require detailed
specification of materials and methods used in the study
to allow other scientists to challenge the conclusions and, if
necessary, repeat the experiments. For comparisons of
cropping systems with different management strategies, the
following specifications and data are required:
1. Definition of the systems to be compared. For example,
is the goal to compare organic and conventional systems
when both utilize the best available technologies and
crop rotations for a given field and region? In this case,
researchers must strive to identify best management
practices that optimize performance of each system
separately with regard to input levels and timing of all
crop and soil management operations for the specific
soil and climatic conditions at the research site. In
contrast, most comparisons of organic and conventional
systems utilize a relatively customized set of practices
for the organic system and standard 'recommended'
practices for the conventional system, or practices
thought to represent 'average' practices used by
conventional crop producers in the region. The problem
is that most conventional crop producers also customize
crop and soil management practices to their production
environment, which can vary substantially from field to
field. Hence, a bias exists unless both systems receive
the same degree of concern for optimization of all crop
and soil management practices, for a given site, within
the general guidelines of practices allowed for organic
versus conventional systems.
2. Specification of performance parameters as the basis of
comparison. The most relevant parameter to address the
question of food security is food output per unit areatime.
The time dimension is critical because organic
systems often require rotations that include non-food
crops, such as legume cover crops or lower-yielding
legume crops, to provide nitrogen input from symbiotic
nitrogen fixation. While yield of the same crop species
grown in organic and conventional systems may be
similar, total food output of the cropping system may
differ depending on the rotation. Further specification of
human edible calorie and/or protein yield per unit areatime
is also helpful.
3. Quantifying nutrient input levels and equalizing them as
required. Organic systems typically rely on manure or
compost to satisfy crop nutrient demand and to maintain
soil fertility. But release of organically bound nitrogen
(N), phosphorus (P) and sulfur (S) in manure depends on
biological processes controlled by temperature, moisture
and microbial activity. In fact, only a portion of the
applied nutrients contained in manure are released
during the growing season in which the manure was
applied. Likewise, the total amount of nutrients applied
in manure is usually much greater than total nutrients
applied in conventional systems receiving recommended
rates of commercial fertilizer. Over time, the indigenous
soil nutrient supply in organic systems often increases
compared to that of conventional systems receiving
recommended fertilizer rates. Moreover, manure contains
all essential plant nutrients in addition to N, P and
K-which are the primary nutrients applied in conventional
systems. As a result, researchers comparing
conventional and organic systems must carefully
monitor crop nutrient status to ensure that the conventional
system is not deficient in one or more essential
nutrient because these deficiencies are easily corrected
by application of the appropriate commercial fertilizer.
Such measurements are especially important when
organic versus conventional comparisons are conducted
on soils that do not have high indigenous fertility levels.
4. Appropriate experimental design and treatment replication.
Modern statistical methods were initially developed
in the first half of the 20th century by agricultural
scientists who recognized the challenge of making
scientifically sound conclusions based on results from
field experiments. Spatial and temporal variation in soil
properties and climate require use of statistical theory in
experimental design, treatment layout, and replication.
Results from field studies that do not adhere to accepted
statistical norms are not reliable.
The above specifications and data represent a minimum
standard for making reliable comparisons of different
Forum 83
cropping systems. In my opinion, many of the studies cited
by Badgley et al.6 fail to meet these standards. Therefore, it
is not possible to make sweeping conclusions about the
potential for organic systems to feed the world by simply
comparing yields between organic and conventional
systems. Likewise, even more stringent and comprehensive
specifications and data would be required for valid
comparisons of the environmental impact of organic versus
conventional systems-including the impact on soil
quality, water quality as affected by nutrient losses, and
greenhouse gas emissions. One cannot simply assume that
organic systems are more environmentally sound because
they do not use commercial fertilizers and pesticides.
In fairness to those who conducted most of the studies
cited by Badgley et al.6, the conduct of scientific studies of
publishable quality does not appear to be their primary
goal. Many seem to be demonstrations and informal trials.
While such trials may have educational value, they are not
an appropriate basis for scientific inquiry. In conclusion, the
question of whether organic systems can feed the world
remains unanswered.
Given the need to produce 60% more food by 2050 to
meet demand from growth in both population and income,
and to do so with less land and water for irrigation, there is
an urgent need for a process of 'ecological intensification'
of crop production systems7. A focus on existing conventional
and emerging organic systems limits the possibilities.
Instead, the emphasis should be on developing cropping
systems that best contribute to a set of well-defined
performance parameters that ensure adequate food supply,
farm family income, and protection of environmental
quality and natural resources. If a system meets these
criteria, it should not matter whether it complies with rules
prescribed for organic production systems, or any other
arbitrary set of prescriptions for crop and soil management.
The trend of decreasing funds for agricultural research in
the public sector dictates a more efficient approach; one
that focuses on outputs (broad sense-including environmental
impact) from agricultural systems rather than on the
type or source of inputs.

Editorial response by Jim Hendrix
'Farming looks mighty easy when your plow is a pencil
and you're a thousand miles from the corn field.' Dwight
D. Eisenhower
When Eisenhower made the above observation in 1954,
our nation was one to two generations removed from
the realities of farming. In the intervening 53 years,
certain segments of our society have come to idealize
agriculture with a desire to connect to small-scale organic,
family-operated farms and to demonize large-scale commercial
farms. 'Organic agriculture and the global food
supply', by Badgley et al., exemplifies the perspective of
some scientists in the academic world who favor organic
practices without having a grounded knowledge of the
economics and drivers of food production.
I am a large-scale crop producer in the high plains region
of Colorado, Kansas, Nebraska and Texas. We utilize
center pivot irrigation on coarse sands, practice integrated
pest management, and are early and consistent adaptors of
technology to substitute capital for labor. We operate
several farms utilizing conventional inorganic fertilizers,
pesticides, crop rotation and minimal tillage to produce
corn, edible beans and alfalfa. I am also involved with a
large-scale organic farm and dairy-feeding operation in
which we grow grain and alfalfa to produce organic milk.
This combination of production practices, employing both
organic and inorganic farming techniques, gives me insight
into production costs and problems associated with both
systems.
The Badgley et al. article misses the mark in several
critical areas. In production agriculture, farmers respond to
market signals and nitrogen is just one consideration.
Organic fertilizer benefits are measured based upon N
content and, in some cases, the content of other nutrients.
84 Forum
However, these nutrient additions are worth only the sum of
their parts; organic nutrients convey no 'magical' properties.
Because economics drive production, all sources of
nitrogen will be used in the production of food, and
combinations of organic and inorganic nitrogen are often
used on the same farm. Likewise, the decision to include
legumes in a crop rotation is made to maximize economic
return and is based upon long-term fertility, current
profitability, availability of labor and management, marketing
opportunities and a host of other factors.
I question the validity of the statement that production
per unit area is greater on small farms than on large farms.
'Large' farms generally maximize land, labor, machinery
and management to lower the unit cost of the commodity
being produced. Over time, commodities always trade at
the average cost of production, leaving little room for
producers who are high cost due to low volume.
It is elitist to condemn people to the drudgery of hand
labor required on small organic farms; only those who have
never done such work believe it is an employment solution.
Throughout history, farm producers have sought productivity
gains by substituting animal for human labor,
designing and employing simple machines and, most
recently, using information technology, remote monitoring
and sophisticated machinery. It is unreasonable to believe
that agriculture will return to hand labor to reduce
unemployment or underemployment.
The final fallacy in the Badgley et al. article is the
insinuation that organic farming is an advanced method of
crop production that always leads to better soil tilth, less
erosion and superior nutrition. In our experience, organic
corn requires soil tillage prior to planting and cultivation
during the growing season to control emerging seedling
weeds. These operations destroy organic matter, reduce
the water-holding capacity of our light sands and increase
soil susceptibility to wind erosion. In contrast, our
transgenic corn is planted into winter cover crops which
are killed with herbicides after planting. Later, developing
weeds are controlled with additional herbicides instead
of mechanical cultivation. These conventional farming
practices allow us to maintain a protective residue
cover on the soil surface and increase soil organic matter
inputs.
As a large-scale producer of organic and conventional
food products, I would like to share a few insights into the
crops that we produce. Generally speaking, as we move into
more specialized crops and end products, organic farming
becomes more difficult and expensive. For example, there
is little difference in the cost of production or yield between
organic and inorganic alfalfa. Insect and weed pressures are
generally controlled with an early harvest, although this
may change with new transgenic alfalfas that offer a longer
stand life. On the other hand, dry edible beans are difficult
to grow organically. They do not compete well with weeds
and are subject to bacterial, fungal and rust infections and
insect infestations which can cause considerable loss in
both quantity and quality. Furthermore, organic bean yields
are typically less than half of those for conventionally
grown beans. The primary consumers of dry edible beans
are generally unwilling to pay for the higher cost of organic
production.
Production issues for organic corn fall somewhere
between those for alfalfa and dry edible beans. Producers
can access the highest yielding non-transgenic hybrids. In
organic corn production, our limiting factor has not been
nitrogen or other crop nutrients, even though total fertility
costs are about 40% higher when compared to inorganic
forms of fertilizers. Rather, soil insect pressure during stand
establishment and the effective control of insects during the
growing season have reduced organic corn yields to 80-
85% of conventional. Overall, our cost per unit of
production has been approximately 30% higher for organic
compared to conventional corn.
In our operations, the economic driver for organic corn
has been the production of a feed source for organic milk.
Additional costs associated with organic production have
been borne, to date, by the marketplace where wholesale
organic milk is currently over twice the price of conventional.
Consumers of organic milk believe there is
economic and nutritional value in their purchase. Yet,
using the latest advances in laboratory testing, we have
been unable to demonstrate any difference in the nutrient
content between our organic and conventionally produced
milk. By purchasing organic milk and other organic
products, I also believe that consumers feel they are
supporting the idealized image of a small-scale organic,
family-operated business. This is rarely the case.
Although economics will dictate how long we produce
organic milk, we question the morality and sustainability of
organic production. Given its inherently higher cost, are
families purchasing less milk to the detriment of young
children? Would these children be better served with larger
quantities of nutritionally equivalent conventional milk?
The same questions can be asked with regard to organic
fruits and vegetables.
In the developed world of agriculture, producers
respond to market incentives. Given sufficient net returns
to attract adequate capital and management, producers will
industrialize the production of organic food. We are not
driven by ideological concepts, political correctness or
environmental persuasions; we are driven by the marketplace.
Farmers always respond to incentives in the market
and will produce sufficient food using combinations of
conventional and organic methods to maximize their
individual net returns.
