The Green Revolution:

Criticisms

Criticisms of the Green Revolution

Food Insecurity of poor not addressed

Cash Crops: food flows from the poor and hungry nations to the rich and well-fed nations

Green Revolution not sustainable

– destroys resource base on which agriculture depends

India

Example: India

Self-sufficient in grain due to Green Revolution

But 1/3 of people poor

5,000 children die each day

Poor cannot afford to

BUY the food

Criticisms of the Green Revolution

Early, poor had little access to credit

Could not buy seeds, fertilizer, irrigation to make

Green Revolution work

Wealthy invested, got richer, drove out poor

Now, more emphasis on loans for poor

There are still problems

Need good land (wealthy own)

Agrochemicals bad for health, environment

Expensive inputs: profits to global chemical companies

Rural people displaced from land

Mechanization reduces agricultural jobs

Not ecologically sustainable: depletes soil, pesticide race

Farm Squeeze

Fertilizer use increases by huge amount

Yields do not increase proportionally

India: 6x rise in fertilizer use but 2/3 less production/ton fertilizer

Need more fertilizer, pesticide each year for same result

Thus cost go up faster than yields: cost-price squeeze

Farm Squeeze

U.S. true home of Green Revolution

Yields up 3x

– but prices down

To survive, must expand acreage

– to make up for lower per acre profit.

U.S. Farm Squeeze

Since WWII

– number of farms decreased 2/3

– average farm size up ½

– rural communities gutted

– production costs up from 50% of gross to 80%

Soil Depletion Worldwide

Dramatic increases in yields during 1970s,

1980s

Soil now depleted, resulting in leveling off or dropping yields

6% of Ag land in India now useless

Brazil

Profits

Profits from Green

Revolution go to

– Middlemen

– Banks

– Chemical companies

– Biggest growers

Grain prices fall

Farms get bigger

Increased Dependency

Poor countries must import:

– Seeds

– Fertilizer

– Pesticides

– Herbicides

Cost to India increased

600% 1960-1980

Biotechnology leads to more dependency

Unsustainable Agriculture

Industrial agriculture =

– mining land to extract maximum output

• “War” between humans and weeds, insects and disease

Market dictates weapons:

– pesticides and chemical fertilizers

We are destroying our foodproducing resources

Destruction of Ag Resources

Desertification

Soil erosion

Pesticide contamination

Groundwater depletion

Salinization

Urban sprawl

Genetic resources shrinking

Fossil fuels depleting

Genetic Engineering:

The Next Green Revolution ?

Next Green Revolution?

Biotechnology will help developing countries accomplish things that they could never do with conventional plant breeding”

• “I believe genetically modified food crops will stop world hunger.”

Norman Borlaug

Nobel Peace Prize

The Next Green Revolution?

Biotechnology helps farmers produce higher yields on less land.

Technology allows us to have less impact on soil erosion, biodiversity, wildlife, forests, and grasslands

To achieve comparable yields

(1950-1999) with old farming methods, would have needed an additional 1.8 Billion hectares of land

Norman Borlaug

Nobel Peace Prize

Biotechnology Critic

Biotechnology development

– Same vision as chemical industry:

Short term goals

Enhanced yields, profit margins

Nature should be dominated and exploited

– forced to yield more

Prefer quick solutions

– to complex ecological problems

Reductionist thinking about farming

Instead of integrated systems

Agricultural success means

Short term profits

Not long term sustainability

-Jane Rissler, Union of Concerned Scientists

Review

• History of theory in anthropology

• Unilinear, relativism, symbolism, materialism, humanism

• Flat Earth

– Positive aspects of globalization?

• Falling Flat

– Negative aspects of globalization?

Systems Theory

• Originated in the 1940's

– Positivistic period in sciences. What does positivism mean?

• Biologist Ludwig von

Bertalanffy (General

Systems Theory, 1968)

• Ross Ashby

(Introduction to

Cybernetics, 1956).

Systems Theory

• Reaction to reductionism in science

• Attempted to revive a unified theory in science

• What does this mean?

– General Theory

– Holism

– Positivism

Systems Theory, What is it?

• Systems are sets of covariant entities no subset of which is unrelated to any other subset

Systems Theory is the trans-disciplinary study of the abstract organization of phenomena, independent of their substance, type, or spatial or temporal scale of existence

Systems Theory, What is it?

• To be a system requires organization and interdependence

• An grouping of functioning parts that are not interdependent is described as a Heap

Systems theory, what is it?

• Systems theory looks beyond functional cause and effect models

• It portrays human adaptation in terms of wellspecified webs of mutual causality.

• Is a way of looking at the relationships among variables

Systems Analysis

• Systems analysis focuses on the meaningful interactions of the parts with one another and with the whole as they influence some process or outcome

• No elemental part of the system can be understood only in terms of itself

• Systems can be understood by studying the interactions of a functioning part with the entire system

• Systems are shaped by both internal and environmental processes and conditions over time

Systems Analysis in Anthropology

• Excellent theory for describing flows

• Excellent for describing closed systems

• Problems?

• No closed cultural system

• What does this mean?

• Systems thinking tends to be processual (time and space), conditional, and probabilistic

The Idea of a System

• System in its everyday sense

• Nervous system

• Legal system

• Cooling/Heating system

– Automobile cooling system

• Radiator

• Fan

• Water pump

• Thermostat

• Cooling jacket around the cylinder head

• Hoses/clamps

The Cow

• Cow, like all organisms, is a very complex system

– Circulatory system

– Nervous systems

– Digestive system

– Study digestive system to understand how cow lives on grass (total system)

• One we use to turn grass into milk

– Also part of a number of larger systems

– If kept with other cows, part of Herd

= social organization of cows

– Study cow as part of herd to understand herd

OTHER EXAMPLES OF SYSTEMS COWS

ARE PART OF?

Stable Systems?

• Collection of smaller parts more stable over time than one large operational part

– Scientists made atoms of bigger and bigger size, and they became more unstable the larger they were

What systems need

• Energy and information is needed to fuel systems

• The more complex the system, the more energy and information is needed

• Inputs and Outputs

Feedback

• Systems can transform things

• Input / Output

• Information about the result of a transformation is recorded

• If this information affects the transformation in a positive way – positive feedback = leads to accelerate the transformation

• If this information affects the transformation in a negative way – negative feedback = leads to system stabilization

Wallerstein and the Global Economic

System

• Emmanuel Wallerstein

• U.S. sociologist

• Historical social scientist

• World-systems analyst

• The Modern World-

System, 1974, 1980, and 1989

• Marx, history of exchange networks,

Dependency Theory

Dependency Theory

• Before World Systems

Theory, there was…

• Dependency Theory

• Social science theories predicated on the notion that resources flow from a "periphery" of poor and underdeveloped states to a "core" of wealthy states, enriching the latter at the expense of the former.

World Systems History

• The late 18th and early

19th centuries marked a great turning point in the development of capitalism

• Capitalists achieved statesocietal power in the key states which furthered the industrial revolution marking the rise of capitalism

• UK and USA

World Economy

• “World Economy” integrated through the market rather than a political center

• Two or more regions interdependent and two or more polities completing for dominance

• Division of labor

“Core“ of "free countries“ dominating others without being

Dominated

“Semi-periphery“ the countries which are dominated while at the same time they dominate

Others

“Periphery" as the countries which are dominated

World System

• Multicultural territorial division of labor in which the production and exchange of basic goods and raw materials is necessary for the everyday life of its inhabitants

• Division of labor: the forces and relations of production of the world economy as a whole

• Leads to the existence of two interdependent regions: core and periphery.

World System Theory

• World-system theory is a macrosociological perspective that seeks to explain the dynamics of the

“capitalist world economy” as a “total social system”

• “Man’s ability to participate intelligently in the evolution of his own system is dependent on his ability to perceive the whole”

(Wallerstein 1974:10)

Core and Periphery

• Powerful and wealthy

"core" societies dominate and exploit weak and poor peripheral societies.

• Technology (both military and civilian) is a central factor in the positioning of a region in the core or the periphery

World-systems analysis

• Capitalism, as a historical social system, has always integrated a variety of labor forms within a functioning division of labor

• Countries do not have economies, but are part of the world-economy.

Modern Capitalist World Economy

Unequal exchange: the systematic transfer of surplus from semiproletarian sectors in the periphery to the hightechnology, industrialized core

• Capital accumulation at a

global scale: necessarily involves the appropriation and transformation of peripheral surplus

Modern Capitalist World Economy

Imperialism: The domination of weak peripheral regions by strong core states.

Hegemony : The existence of one core state temporarily outstripping the rest.

Global Class Struggle: The inherent conflict between the owners of the means of production and labor.

• What is the inherent conflict?

World Systems Theory as a Criticism

• Criticisms to modernization

• (1) the reification of the nationstate as the sole unit of analysis,

• (2) assumption that all countries can follow only a single path of evolutionary development,

• (3) disregard of the worldhistorical development of transnational structures that constrain local and national development,

• (4) explaining in terms of ahistorical ideal types of

“tradition” versus “modernity”,

Present State of the Theory

• SUNY Binghamton, at the

Fernand Braudel Center for the Study of Economies,

Historical Systems and

Civilizations

• Journal of World Systems

Research

• Greatest impact among intellectuals in the periphery countries

• Used to analyze development dynamics and to understand the relationship between developed and developing regions
