Ancient Agriculture: Roots and Application of Sustainable Farming by Gabriel Alonso De Herrera (Ancient City Press) is the first English translation of the book that carried traditional farming techniques from the Old World of Europe to the New World of the Americas. The original book, Obra de Agricultura by Gabriel Alonso de Herrera, was initially published in 1513 as an instruction manual for the farmers of Talavera de la Reina in central Spain. It was revised several times as the author learned increasingly more about land use and sophisticated irrigation techniques beyond the Iberian Peninsula, which Moorish farmers of the day had blanketed in exotic fruits and vegetables.
Historically, Herrera's agricultural classic has been especially relevant in arid regions of the world, where crops are irrigated by means of ditches such as acequias, sangrias, and arroyos, which also crisscrossed the landscape of Spain at the start of the sixteenth century. Many of Herrera's planting, harvesting, and seed-saving tips have, in fact, been successfully integrated into Indo-hispanic farming practices in the southwestern United States, where drought conditions and the need for water conservation typically prevail. The present edition, Ancient Agriculture, has been meticulously translated, illustrated, and compiled for contemporary use. Areas of focus include working the land in harmony with nature and producing more food through soil improvement, cultivation of vineyards, and awareness of astrological influences. The interweave of ancient farming traditions and modern realities of global warming makes this treasure trove of the past a seedbed for a whole new generation of farmers and gardeners striving for agricultural sustainability. GABRIEL ALONSO DE HERRERA, considered the father of modern-day Spanish agriculture, lived in central Spain from the time of his birth, in the 1470s, until his death, around 1540. He learned about agriculture from working in the fields of Talavera de la Reina with his father, in Granada with the Moors, studying Spanish Arabic and classical Roman texts on the subject, and traveling extensively throughout Europe. JUAN ESTEVAN ARELLANO, a journalist and farmer native to northern New Mexico, has roots reaching back to the 1725 settlement of the Embudo Valley. A poet and novelist as well, he is the 1994 recipient of Mexico's Premio Nacional de Literatura Jose Fuentes Mares prize.
The Changing Scale of American Agriculture
by John Fraser Hart (
The increased scale of agriculture has outmoded the Jeffersonian ideal of small, self-sufficient farms. In the past, farmers kept a variety of livestock and grew several crops, but modern family farms have become highly specialized in producing a single type of livestock or one or two crops. As farms have become larger and more specialized, their number has declined.
Hart contends that modern family farms need to become integrated into tightly orchestrated food-supply chains in order to thrive, and these complex new organizations of large-scale production require managerial skills of the highest order. According to Hart, this trend is not only inevitable, but it is beneficial, because it produces the food American consumers want to buy at prices they can afford.
Although Hart provides the statistics and clear analysis such a
study requires, his book focuses on interviews with farmers: those
who have shifted from mixed crop-and-livestock farming to cash-grain
farming in the

Ecological Agrarian: Agriculture's First Evolution in 10,000
Years by J. Bishop Grewell, Clay J. Landry
(Purdue University Press) details how agriculture is
moving from feeding a growing planet to feeding a planet with
environmental concerns. Explains how agriculture shaped history, and
argues that we are entering an unprecedented era where the demands
on, and the focus of, agriculture are changing.
Further declines in the use of pesticides, fertilizers, and other inputs are no doubt on the way. Improvements will not only make agriculture more efficient and productive, but also help the environment. Advancements in the use of computers and global positioning satellite (GPS) systems are being used to measure how much seed, fertilizer, or pesticide are placed on a spot of land and how much in turn is harvested. This "precision farming" increases yields while decreasing inputs. In addition, using cheap equipment such as rain gages and barometers connected to computers helps farmers know when to apply pesticides and what kind to apply so as to minimize environmental harm and maximize output.
For instance, Rick Hartley runs a spraying business near
Attleborough, Norfolk in the United Kingdom. Before crops are up,
Hartley identifies patches of thistles that can be seen when he
drives by with his sprayer. When he reaches a patch of thistles, he
douses it with herbicide and then turns his sprayer off until
arriving at a new patch. Applying the herbicide only where needed
lowers expenditure of the chemical. When interviewed by a U.K farm
weekly, Hartley explained, "While it is easy enough to do that the
first time through the crop, the second dose of the split treatment
goes on when the beets are up and the thistles largely hidden. As a
result, you can not be as selective without the risk of misses.
Before precision farming, Hartley's second trip through the beets
required him to spray everywhere to make sure he got all of the
thistles. Today, Hartley marks the locale of thistles his first time
through with a GPS system. When he returns for the second spraying,
the GPS directs where and when the sprayer should be turned on and
where and when it should be shut off. This saves on herbicide and
lowers cost. Such patch spraying has the potential to lower
herbicide costs by up to 50 percent.'
Other precision farming techniques employ infrared systems to
monitor yields. By scanning a field, infrared provides information
on plant density. Computers using geospatial information systems
(GIS) turn this data into digital maps. In places where growth is
low, farmers can change their mix of inputs to try for a better
result. Linking soil samples taken in a field with GPS mapping can
identify where farmers and their equipment should apply more or
less fertilizer. This leads to more efficient and cost-effective
fertilizer application. In his book Agriculture and Modern
Technology: A Defense, Thomas DeGregori observes, "Farmers generally
do not wish to use inputs, such as seeds, fertilizer, and pesticides
needlessly, since they cost money."81 By using information as a
substitute input, the other inputs can be lowered. DeGregori goes on
to note that precision farming technologies are currently only
practical for use by large farms in the developed world. The
challenge is to make them more affordable for poorer farmers in
less developed areas.
Being dynamic and responsive, agriculture is not only changing in
the demands that it is meeting and the problems that it is solving,
it is undergoing change in its structure. In the period from 1940
to 1998, the number of farms in the U.S. dropped from over 6
million farms to just over 2 million farms.' From 1970 to 1990, the
number of farms dropped 27 percent.'
Meanwhile, average farm size rose from 174 acres in 1940 to 435
acres in 1998.5 Whereas 92.6 percent of the farms in 1970 were
taking in less than $40,000 per year in cash receipts, by 1990 that
number had dropped to 70.7 percent. Farms are consolidating into
larger, bigger income operations.'
Contrary to popular thought, this emphasis shift to larger, more
intensive farms is nothing new in agriculture. In 1925, N.S.B. Gras
wrote of agriculture:
The agricultural contest may be expressed in many different ways
with varying shades of emphasis. It is generally the small farm
against the large farm, the homestead against the plantation, and
the new and improved system against the old. It is the new system
that wins. And this new system generally grows up in old lands
competing with the old system. The victor is almost invariably a
more intensive form of agriculture.' Compare those words to Samuel
Staley writing at the end of the twentieth century:
... agriculture is changing. Farms are getting larger, and small family farms are increasingly less financially viable. Most family farms, in fact are supported by income from off the farm. Nationally, 49.7 percent of farmers report an off-farm source as their primary income, and 37.1 percent said they worked 200 or more days off the farm. Slightly more than 25 percent of the nation's 1.9 million farms earn more than $50,000 per year in sales, while the average net-cash return is just $22,260 per farm. As land becomes less and less important as a source of productivity, farms are becoming even more vulnerable to competitive pressures to expand their operations to capture larger economies of scale or to shift uses into nonagricultural activities such as housing, offices, recreation or open space.'
Agriculture's Environmental Evolution
As we set out at the beginning, agriculture is evolving for the
first time in its history. Its purpose is no longer only to feed
people. This book focuses on that evolution toward meeting new
demands from consumers. It asks how the agrarian sector is dealing
with the new problems created by the solutions of yesterday and what
frameworks can help it succeed.
The answers to agriculture's next stage are already out there. In
part, it relies upon the old path of continuing to increase yields
through technology. If it isn't broke, don't fix it. Biotechnology
and precision farming are but two of the answers being researched
for the purpose of increased yields. But there is also the shift
toward meeting other demands beyond the simple scope of a frill
belly. This part of the answer is where agriculture's evolution
Supplying the environmental amenities for a new generation of
demands offers a chance for agriculture to expand its revenue. For
many farmers and ranchers, the only way of staying in business is
turning toward green options. These options rely on a new revenue
source, more efficient use of available resources, or capturing a
premium price for their current products by employing production
methods that have a philosophical appeal to consumers. It is not
ecological leanings on the part of agricultural producers turning
them green, but rather the financial rewards for doing so.
In the next chapter, "The Color of Money," we explore two of the
methods mentioned. By using markets for green products, producers
improve their business through new revenue opportunities. They also
achieve premium prices for products certified green in their
production. The chapter discusses the efforts of ecological
agrarians to gain new revenue opportunities from producing green
products and how premium prices and market share can be captured
through green brand names and labeling.
In chapter three, "Waste Not, Want Not," we write about more
efficient resource use. Farmers and ranchers take in the waste of
other industries and one another as they produce their own products.
Applying the same idea in reverse, industries take in waste leaving
the agricultural sector.
This lowers the costs of disposal for agriculture, cleans the
environment, and in some cases, the agricultural producer often
receives payment for the waste materials. Marketplace recycling
turns one business's trash into another business's treasure.
Chapter four unearths the efforts of landowners and land trusts
to manage the environment for the environment's sake. Unlike the
other chapters, some of the landowners in this chapter are less
motivated by profit and more influenced by their own sense of
environmental value. Some operations in the chapter do, however,
capitalize on a growing demand for agricultural tourism and fee
recreation to cover their costs and generate revenue.
Chapter five turns to the habitat that agriculture provides for
the nation's wildlife. In return for habitat provision, many
landowners are finding revenue opportunities by providing prime
hunting for a fee. In addition, environmental organizations are
willing to pay landowners to leave some of their irrigation water in
stream to help struggling fish populations. The chapter looks at
how such new opportunities are arising and how institutional changes
at the state level are helping them flourish.
In chapter six, Greg Conko documents the advances made via
biotechnology to improve resource use by the agricultural sector.
From plants that can live on saltwater to bug-resistant varieties
that reduce the need for pesticides, biotech is turning agriculture
on its toes and benefiting the environment. At the same time, it is
creating a second "Green Revolution" to feed growing numbers of
people without increasing the need for more land.
After demonstrating agriculture's evolution in each chapter, the
book concludes with a look at where we go from here in the final two
chapters. Chapter seven lists environmental harms that have arisen
in agriculture's fight to feed the planet and explores institutions
that have exacerbated such harms. Chapter eight synthesizes the
lessons learned throughout the book to ask what institutions entice
agriculture into evolving for the sake of improved environmental
quality and what institutions fail. It provides a framework for
nurturing agriculture forward.
Agriculture's greatest triumph in the environmental arena was
feeding the world with increasing yields that protected much of our
wildlife habitat from agricultural conversion. But that success was
in many ways an unintentional side effect of trying to feed the
world. It is now embarking on protecting the environment as an
explicit goal demanded by its customers. For the first time in
10,000 years, it has a purpose beyond food production. The fresh
challenge lies in maintaining the success of the past while working
toward achieving new environmental endeavors. Capturing the dynamic
ingenuity of agrarian entrepreneurs, agriculture's evolution says
we can have our cake and eat it, too.
The stories of those carrying agriculture into its new evolution
are the ones we capture in this book. We hope the eco-entrepreneurs
discussed here will inspire others to plant the environmental seed
through imitation or original ideas of their own. We also hope this
work encourages the development of the institutions necessary for
agriculture's evolution to be successful. By encouraging
experimentation and rewarding those who do well, agriculture can
enter into the next millennium as an important part of civilization,
just as it was over the last ten thousand years. It can be more
dynamic than ever. And it can do so, knowing that not only is it
feeding the world's population, but it is also nurturing the planet.
The stories provided here are but a glimpse of agriculture's
future. In time, their solutions may prove obsolete as the
environmental problems of today become problems of the past. No
doubt when they are solved, a new set of dilemmas will arise, and
agriculture will evolve again. We will leave finding the answers to
that next stage for the thinkers of tomorrow.
