Definition of Food Security

FAO 2008

Food security and Human development

• FS and human development hand in hand

• 1 billion in hunger + 1 billion undernourished

• 29 millions died from hunger 2014

• 694 millions obese persons 2014

• 574 ton food waste 2014

Page 6: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

What is affecting Food Security?

Supply side pressures

Global Environmental Change

Urbanisation

Globalisation

Demand side pressures

Urbanisation

Population increase

Poverty

Constraints on access

Inequality

Consumption pattern in the North

Time dimensions of human food acquisition systems

100.000 BP Homo sapiens – collector and hunter

12.000 BP agriculture Middle East

10.000 BP domesticated sheep, goats Middle East; Deglaciation in N Europe

6.000 BP agriculture – moving arables, Scandinavia

1.500 BP agriculture - permanent arables

60 BP agriculture – independent of local ecosystems

25? BP agriculture - globalised production

Olsson 2002

100.000 10.000

Human nutritional needs

• Basal needs for growth, development & regeneration of human body and mind

• 2100 kcal daily

• Food habits – consumption pattern – CULTURE?!

Swedish meat

consumption in 2010:

85 kg per capita and

year

Influence of production method on resource use…

Godfray et al. 2013. in

Science

Page 11: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

Nitrogen and Phosphorus

• Essential nutrients for biomass growth,

agricultural fertilizers

• Deficit of N, P – no growth -> death of

organisms

• Excess of N, P -> Pollution of ecosystems ->

Decrease and disruption of ecosystem

services and climate stability.

• N as gas (78%) in the atmosphere –

inaccsessible for most organisms.

Synthetically produced today – chemical

fertilizer

• P in bedrock and sediments in lakes, sea

Unprecedented change in structure and function of ecosystems

More land was converted to cropland in the 30 years after 1950 than in the 150 years between 1700 and 1850

Page 13: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

Changes to ecosystems have provided substantial benefits

– Food production has more than doubled since 1960

– Food production per capita has grown

– Food price has fallen – until 2003

MA 2005

Increasing agricultural yields…

Page 14: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

Rising food prizes...

• Competing demands on agricultural land: peaking resources… biofuels, agro regimes…

• Degraded land

• Climate warming

• Changing food patterns

Steffen et al.

Can we feed 9 billion people on this planet?

• Production capacity

• Distribution and Environmental justice

• Power and equality

• Globalization

• ’Consumption pattern in the North is driving hunger in the South’

Effects of industrial agriculture – rising yields…

• Climate – local and regional – driving global climate change • The global nutrient cycles: Nitrogen and Phosphorus • Water availability - different scales: arable and landscape

scales • Degradation of Soil fertility – less organic content, degraded

capacity to store and circulate nutrients • Biological diversity – different scales: arable and landscape

scales; Protection and resilience to pests and deceases • Crops – the genetical material: resistence to diseases,

genetic variation gives resilience to environmental change; seed banks; agro-industrial complex…..

• Animal raising and meat production…?

Page 17: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

Effects of globalized food market See Kneafsey et al. 2013

• Transports between contintens of food products; feed, fertilizers, energy…

• Effects in the North, in Europe, on resilient food production?

• Effects in Europe on vulnerability ?

• Effects in the South on resilient food production? Vulnerability?

Effects on resources of food production methods

Page 20: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

Sustainable and resilient food production today and tomorrow?

Chappell & La Valle 2011; Björklund et al. 2012; McKenzie & Williams 2015

• Vulnerability of food production increased by Climate change – GEC. This demands less vulnerability in other factors & more resilient food systems

• Independent of environment and biodiversity?

• Food to 9 billions – by yield increases from technological factors?

• Other factors more influential: access; culture, ecology, knowledge, participation …

Food sovereignty

Food sovereignty is defined as the right of peoples and sovereign states to democratically

determine their own agricultural and food policies

IAASTD. 2008: International Assessment of Agricultural Science and Technology for Development , an intergovernmental panel; United Nations and World Bank

Page 23: Food Security and Global Environmental Change€¦ · Ericksen P. 2008. Conceptualizing food systems for global environmental change reserach. Global Environmental Change 18: 234-245

Food system approach?

• Help in identifying the range of involved issues and actors

• Provides a framework to address multiple vulnerabilities

• Assist in determing main limiting factors for food security
