CLASH OF PARADIGMS
Industrial agriculture
(Green Revolution)
Small scale agriculture
(Agroecology)VS.
Industrial agriculture occupies 80% of arable land
with homogeneous monocultures that are highly
vulnerable and exert a huge ecological footprint
Worst drought in 50 years
plundered yields of corn
and soybean in Midwest
California 2014:
400,000 acres left
fallow, $1.5 billion
losses
Puerto Rico’s
Monocutlure Plantations
Decimated by
Maria:2017
Industrial agriculture does not feed
the world and warms the planet
• Produces only 30% of global food
• Uses 70-80 % of arable land
• 5.2 billion pounds of pesticides
• 70% water and 80% fossil fuels
• Produces > 30% of GHGs
• WARMS the PLANET
Greening the green revolution
will not work for the transtition
to more resilient systems
• Masking the problems of industrial agriculture
on concealing its symptoms and impacts
• It is not only about reducing the impacts of
industrial agriculture maintaining
monoculture structure : climate smart
agriculture, sustainable intensification, etc
• Business as usual will not work …………IAASTD
The evidence in favor
of agroecology
• A growing number of reports
suggest significant potential
social and environmental gains
from transitioning toward
agroecological agriculture as a
way to nourishing current and
future populations sustainably.

Peasants and
world food
1,5 billion small
famers in < 2 ha
plots produce 50-
75% of food
consumed by world
population, using:
• 25- 30% of the
agricultural land
• 30% water and 20 %
fossil fuels
• Preserve 1.9 million crop
varieties
• COOL the PLANET
(ETC, 2014)
Peasant diversified farming systems
Huracan Mitch-
Central America
• In Central America,
diversified farms with soil
conservation practices
suffered significantly less
erosion and mudslides
– resisted more the
impact of hurricane
Mitch in 1998 than
farms managed under
monoculture (Holt-
Gimenez 2002).
Huracan Ike-Cuba
Areas under industrial monoculture suffered more damage and exhibited less recovery
than diversified farms.
After the hurricane average loss in diversified farms was about 50% compared to 90-
100% in monocultures
Productive recovery was about 80 - 90%,and was noticeable 40 days after the
hurricane

Impacts of the restoration effort in
Comunidad Bellavista-Colombia
• 75% recovery of forest cover
• Water conservation and
rational use (available for
families- increase from 25 to 75
families)
• Diversification of production
systems -70% reduction in use
of esternal inputs)
• Food security (families produce
90% of what they consume)
• Community cohesion,
participation of women and
yound people
MIXTECA ALTA, MEXICO
Ecological restoration by farmers Mixteca alta, Mexico
CEDICAM-Mixteca
• In a period of 5 years more than 1 million
trees planted
• Soil conservation and water harvesting
practices implemented along with
recuperation of locally adapted crop
varieties and polycultures to ensure
agricultural productivity
• More than 1,000 farmers trained on
agroecology and more than 500 hectares
restored.
Agroecology
Ecological
Restoration
Sustainable
and resilient
agro-
landscapes
Produce healthy and
accesible food in
harmony with
surrounding
environment
Recover capacity of ecosystems to
provide ecological goods and services
to society
Agroecological restoration for resilient
landscapes
Resilience as a result of how effectively the enhanced
reactive capacity of a community is able to reduce
vulnerability and therefore climatic risk
An effective adaptation strategy evolves from coping to adjusting to climatic
variability, although the ultimate goal is the transformation of the vulnerable system
