Foodprin(ng: Introduc)on to the seminar
Ma.hew Fielding Swedish Interna(onal Agriculture Network Ini(a(ve -‐ SIANI
Presented at “Six feet under: The role of soil carbon in tackling climate change”
24/5/2013

Overview
• Nature is the basis of our well-‐being and our prosperity. • Demand on natural resources has doubled since 1966
and we are currently using the equivalent of 1.5 planets to support our ac4vi4es
• High-‐income countries have a footprint five 4mes greater than that of low-‐income countries.
• “Business as usual” projec4ons es4mate that we will need the equivalent of two planets by 2030 to meet our annual demands.
• We can reduce our footprint by producing more with less, and consuming wiser and be.er.

Overview Why foodprin4ng relevant to this seminar? • To show soil carbon sequestra4on in the context of food
consump4on. • To show the scale of the benefits from soil carbon
sequestra4on when compared to the CO2 emissions.
• To understand the mo4va4on for why we want to store more carbon in the soil.
• To see that soil carbon sequestra4on is just one part of a low carbon future.

What is Foodprin(ng?
www.siani.se
• Stockholm’s foodprint is
28,500km2 (SEI REAP model)
• Stockholm County’s land area footprint is 6,800km2.
• Add an extra 830,000 people
• Plus presuming that ALL of these coun4es can be used for agriculture.

Ecological Foodprint
www.siani.se
Ecological Footprint • Sweden uses markets to acquire this addi4onal produc4on.
• Top 3 sources (based on import/export figures): 1. 1,500 km2 in Brazil 2. 1,325 km2 in China 3. 743 km2 in USA
(Data from EU, REdUSE Scheme)
“Food Security and Nutri4on for All”
(However new research shows Brazilian soy
footprint alone is 1000km2)

Soil Carbon • In the context of massive ecological footprints, high
demand for fer4le lands and the resources they contain, as well as food security issues on top of widespread soil degrada4on, the op(on of increasing soil carbon stocks whilst producing more food on less land is en(cing.

• 367 – 5505 kg CO2/ha/yr can be sequestered in degraded soils through recommended management prac4ces such as:
• No-‐(ll, Nutrient management, Biochar, Landscape management…etc.

GHG Emissions
Stockholm County 4,340 kt GHG emissions
= 4,340,000 tCO2
equivalent =
Carbon sequestered by 14,500 km2 of temperate forests/year
Sweden 18,281 kt GHG emissions
= 18,281,000 tCO2
equivalent =
CO2 emihed by 5.2 coal-‐fired power sta4ons.
“Food Security and Nutri4on for All”
Through looking at GHG emissions from food produc4on on a na4onal scale it is possible to compare the CO2 equivalencies and to show how soil carbon sequestra4on techniques mi4gate these emissions.
www.siani.se
GHG Emissions Soil Carbon Mi(ga(on
5505 kg CO2/ha =
0.055 tCO2 /km2
= Could be mi4gated in
238,700 km2

…In theory.
Stockholm County 4,340 kt GHG emissions
= 4,340,000 tCO2
equivalent =
Carbon sequestered by 14,500 km2 of temperate forests/year

Food Systems
“Food Security and Nutri4on for All”
Enhancements in soil carbon sequestra4on can be easily undone through inefficiencies on the consump4on side via transport, waste ,etc.
Soil carbon sequestra4on must be seen as an essen4al part of the food system but also of a climate mi4ga4on.

Coming up • Coming up today: – Perennial crops poten4al for climate mi4ga4on. – Soil sequestra4on of carbon: poten4als and drawbacks.
– Cahle feeding strategies to influence emissions – Mi4ga4on poten4al of trees in agriculture – How to feed the world whilst keeping carbon locked up.
