The sustainability of terrestrial food production systems is influenced by sociopolitical, economic and ecological factors
Consumers [YOU!] have a role to play through their support of different terrestrial food production systems.
The supply of food is inequitably available and land suitable for food production is unevenly distributed among societies, and this can lead to conflict and concerns.
The sustainability of terrestrial food production systems is influenced by factors such as scale; industrialization; mechanization; fossil fuel use; seed, crop and livestock choices; water use; fertilizers; pest control; pollinators; antibiotics; legislation; and levels of commercial versus subsistence food production.
There are a number of factors that affect how sustainable food production is. Can you match up the factor with an explanation of what it is? Play here!
Too easy? Try playing gravity and see how many factors you can name: https://quizlet.com/418827771/gravity
Work in groups. What words do you think have been blacked out in the image below?
Once you've done: score each farming system, one point for each row it wins on sustainability.
Inequalities exist in food production and distribution around the world.
The State of Food Security and Nutrition in the World provides an excellent summary of these issues - find time to read the key messages and executive summary.
Food waste is prevalent in both LEDCs and more economically developed countries (MEDCs), but for different reasons.

Get ready to share your findings with classmates!
As the human population grows, along with urbanization and degradation of soil resources, the availability of land for food production per capita decreases.
Work individually or in pairs.
Create a Google Doc in your ESS folder
Call it '[Your name] Food and Population'. Share it with me.
Answer the questions below in the doc.
What does this graph tell us?
Why is this a line graph rather than a bar chart?
How does the scale affect our interpretation of the data?
This graph has two Y axes! What would be a good strategy to help analyse this graph?
What is missing from the line on the graph?
What is the overall trend shown here?
What smaller patterns are visible?
How would this impact on our ability to provide equitable access to food?
In what way is a graph a model?
What is the purpose of a graph?
What is the key message of this graph, and how does that impact our access to enough food?
What does this look like in the real world? Visit this OneTab link. These are all recent news stories about:

Rising human populations
Contribute a page to this Google Slides document, including in your page:
A very short summary of the story.
The background/causes of the situation.
An explanation of how it reduces (or increases) the land available for growing food.
The yield of food per unit area from lower trophic levels is greater in quantity, lower in cost and may require fewer resources.
Cultural choices may influence societies to harvest food from higher trophic levels.
Terrestrial food production systems can be compared and contrasted according to inputs, outputs, system characteristics, environmental impact and socio-economic factors.
Socio-economic, cultural, ecological, political and economic factors can be seen to influence societies in their choices of food production systems.
The Agriculture Debate
In two teams you will debate the following statement:
With the World population predicted to rise to 11 billion by 2100, intensive commercial farming is the only way we can ensure the wellbeing of our species.
The team allocated the house will defend the statement and the debate will follow the debate style of:
Opening speaker
Arguments 1-3
Closing remarks
Each speech will be 2 minutes with up to two points of information.
Create your team research in a google slides (make sure to open/save it within your ESS folder). You will need to consider:
Inputs
Outputs
Environmental Impact
Socio-economic factors
Cultural factors
Political factors
Economic factors
System characteristics (i.e. how it interacts with other areas)
You may wish to account for examples of farming systems such as:
North American cereal farming
Subsistence farming in Southeast Asia
Intensive beef production in South America
The Maasai tribal use of livestock
Core resources:
246-247 of OUP book
5.2.1 and 5.2.2 of the Kognity book
We will spent 10 minutes reading and researching individually before breaking off into groups.
Increased sustainability may be achieved through:
altering human activity to reduce meat consumption and increase consumption of organically grown and locally produced terrestrial food products
improving the accuracy of food labels to assist consumers in making informed food choices
monitoring and control of the standards and practices of multinational and national food corporations by governmental and intergovernmental bodies
planting of buffer zones around land suitable for food production to absorb nutrient runoff.
What are you going to do about it?
Congratulations! You have just been appointed as agriculture minister for Placeovia, an central European MEDC of around 7 million people. There is a strong sheep-farming lobby in the country, an industry which provides the people with lamb for their beloved national dish and contributes 2% of Placeovia's GDP. Your party, The People's Party of Placeovia (PPP) manifesto promised the citizens of Placeovia a π500 million investment in improving the sustainability of agriculture. Everyone wants a piece of the π (who doesn't love a Greek pun?) but how are you going to spend it? Write a 2-minute speech for the PPP party conference describing your plans. In attendance will be:
The national press.
Members of the sheep-farming lobby.
Activists from an eco-centric local NGO.
Supportive members of the PPP
As is always the case when you join a national government, your key sources of information will be:
OUP book page 259-260
Kognity 5.2.4
The list of options from above, taken from the ESS syllabus
And you will save the text of the speech in your ESS folder.
