What is Food Security?
“Food Security exists when all people, at all
times, have physical, social and economic access
to sufficient, safe and nutritious food that meets
their dietary needs and food preferences for an
active and healthy life.”

By 2050, 70% will be urban
(mostly in developing
countries)
•
800 million people involved in
urban agriculture and
contribute to feeding urban
residents; 200 million produce
for the market; 150 million
are full-time employees

Urban and Peri-Urban Agriculture (UPA)
http://www.ruaf.org/node/512
Urban agriculture: the growing of plants and the
raising of animals within and around cities.
• Integrated into the urban economic and ecological
system; urban agriculture is embedded in -and
interacting with- the urban ecosystem.
• Provides complementary strategy to reduce urban
poverty and food insecurity
• Enhances urban environmental management
• Contributes to local economic development, poverty
alleviation and social inclusion of the urban poor,
particularly women
• Saves energy (e.g. lower transport and storage
costs)
• Responds to market demand

Decreasing number of farmers
• Canada:
– In 1946, about 1.2 million people worked on a farm as a main job.
– Thirty years later, that number had dropped to a little under half a million.
-- Geoff Bowlby, Labour Statistics Division. 2002.
• U.S.A.: The farming population peaked in 1910. It started
declining in the late 1930’s and accelerated in the 1950’s.
Today, less than 1% claim farming as an occupation (and about
2% actually live on farms). There are only about 960,000
persons claiming farming as their principal occupation and a
similar number of farmers claiming some other principal
occupation. The number of farms in the U.S. stands at about
two million.

FAO SAYS WORLD FOOD PRODUCTION
MUST DOUBLE BY DANIEL SILVA
•
•
•
Global food production, already under strain from the credit crunch, must double
in the next four decades to head off mass hunger, the head of the UN's Food
and Agriculture Organisation said on Monday.
Speaking at the start of a two-day international conference in Madrid, FAO
director general Jacques Diouf said the global economic crisis was already
undermining efforts to tackle food insecurity and the need would become more
pressing in the years ahead.
"We face the challenge now of not only ensuring food for the 973 million who are
currently hungry, but also ensuring there is food for nine billion people in 2050.
We will need to double global food production by 2050," Diouf said.“

Can Asia Learn from Brazil’s Agricultural Success?
Over the last four decades, Brazil has transformed its agricultural sector to become the first tropical
agricultural giant and the first to challenge the dominance of the world’s major food exporters. This paper
examines the secrets of Brazil’s success and ponders whether Asia should try to emulate the Brazilian
model to help achieve food security for its people and contribute to an increased level of self-sufficiency
in the region.

Food (In)Security in Urban Populations By Paul Teng and Margarita Escaler The food crisis at
the end of the last decade and the resulting food riots that occurred in cities all over the world
exposed the vulnerability and fragility of the current global food system and highlighted the
increasing problem of urban food security. Urban households were among the hardest hit by the
food and economic crises as they saw their purchasing power decline drastically. Though
aggregate world food availability was relatively good during this period, access to that food by the
urban poor had been severely compromised. This working paper aims to analyse the factors that
influence urban food security and argues the case for why an urban focus will increasingly matter
in the international discourse on food security. A truly “systems approach” will be needed to study
and deal with the many inter-related factors and players in food security. Too often have
professional communities maintained disciplinary barriers when addressing such complex
problems.

Commentary. Facing Food Shortages: Urban Food Security in An Age of Constraints
Abstract: Seventy per cent of the world’s population are expected to live in urban areas by 2050.
Food production to feed this larger, more urban and richer population will have to be done in the
face of changing consumption patterns, the impact of climate change and the growing scarcity of
land and water. It is time that urban centres take charge to usher in a new era of “urban green
revolution”.
Climate change impacts on agriculture in APEC economies
(Regional/sub-regional)
• Reduced crop, pastoral and rangeland production (South and
east Australia; southeast Asia); reduced yields of rain-fed wheat
and rice (southeast Asia); Northward shift of agric. zones
(China); 40% projected decline in irrigated rice in central and
southern Japan;
• Reduced grain quality (Australia); up to 30% grain yield
reduction by 2080 (Mexico); 73-78% reduction in coffee
production by 2050 in Veracruz (Mexico);
• Decline in potentially good agricultural land (East Asia);
• Loss of farm land due to sea level rise (Southeast and East
Asia); >1 million people to lose land in Mekong delta

CC :MITIGATION AND ADAPTATION
Conceptual framework: CC and Agriculture/Food Security
• Mitigating causes of climate change: Reducing sources of
– CO2
– CH4
– Others
• Mitigating symptoms and effects on agricultural production:
– Water (Excess, Deficit, Irregularity) – Drought, Submergence
– Temperature – Ambient, Water, Soil
– Dimming – Solar radiation
– Rising Ocean levels
• Mitigating effects on food security
– Production and Production Process(es)
– Supply of unprocessed agricultural produce for food (Diversion to
biofuel)
– Distribution
Mitigating causes of climate change -Methane
Reducing methane emissions to atmosphere
• Rice: c 13%
– Changing rice plant architecture and anatomy through
conventional breeding and biotechnology
– Changing farming system from paddy rice to dryland rice
• Livestock: c 17%
– Changing diet composition of rumen livestock
– Changing efficiency and nature of digestive process
through breeding with biotechnology tools
What biotechnologies?
What enablers?
Biotechnology & Climate Change Mitigation
• Reduced fuel consumption on farms through
– Reduced need to spray crops – Fuel savings in 2007
through BT led to a reduction of 1.1 million tons of CO2
– Reduced tillage or no-tillage – leads to reduced CO2
emissions of 89 or 36 kg/ha respectively
• Enhanced carbon sequestration
– More carbon is sequestered through no tillage
• Reduced fertilizer use and N2O emissions
– Nitrogen use efficiency in crops
• Livestock and manure management
• Biofuel crop development
• Third generation biofuel development
Biotechnology & Climate Change Adaptation
• Trait improvement:
–
–
–
–
–
–
–
heat and drought tolerance (Drought-tolerant maize)
waterlogging tolerance
frost, pest and disease resistance
water-use efficiency (e.g. Water-efficient Maize for Africa)
nutrient-use efficiency
early vigor
reduced dependence on low temperatures to trigger
flowering or seed germination
• Reducing water loss from agriculture: Less ploughing
means trapping moisture
Key Messages - I
• Adverse impacts of climate change on agriculture are of great
concern. Food security will remain elusive in several
countries by 2050, if suitable policies and measures for
adaptation to climate change are not in place.
• Agricultural adaptations to climate change are crucial to
achieve not only food security but also water security, and
even energy security, thereby social security &
sustainability.
• Agriculture and forestry sectors contribute around 30% of global
GHG emissions; Their mitigation potential is comparable to
industry and energy supply, especially in developing countries,
and more than that in transport and waste sectors.
• Agriculture offers many low-cost GHG mitigation opportunities.
Income from carbon offsets from agriculture, if properly
recognized in the post-2012 climate regime, can nearly meet
adaptation costs.

What governments fear!
Riots, instability spread as food prices skyrocket
14 April, 2008
(CNN) -- Riots from Haiti to Bangladesh to Egypt over
the soaring costs of basic foods have brought the
issue to a boiling point and catapulted it to the
forefront of the world's attention, the head of an
agency focused on global development said Monday.
"This is the world's big story," said Jeffrey Sachs,
director of Columbia University's Earth Institute.
"The finance ministers were in shock, almost in panic
this weekend," he said on CNN's "American
Morning," in a reference to top economic officials
who gathered in Washington. "There are riots all
over the world in the poor countries ... and, of
course, our own poor are feeling it in the United
States.“
World Bank President Robert Zoellick has said the
surging costs could mean "seven lost years" in the
fight against worldwide poverty.
