Agricultural production for the growing planet
Who eats food every day?
Who wears clothes every day?
Who drinks coffee or tea every day?
Who takes fruits every day?
Who drives or takes buses every day?
The society needs various products from agriculture
Coffee beans, cultivated local people - middle people pay more, higher profit
Fairtrade trying reduce profit so that the middle people give more money to local people
Money spent techniques- local people- improve facilities, reducing H20 consumption, improve ecosystems & QoL fairtrade
Outline
Crop types
Virtual water trading - behind crops new concept how this exchanged between countries
- global trading
Global crop and virtual water trading
Agriculture management
What the society needs from agriculture
Food crops - wheat, rice, corn, potato
Economic crops - cotton, coffee, olive, fruit, sugar
Bioenergy crops- maize, groundnut, crop residues
What the society needs from agriculture
Food crops - wheat, rice, corn, potato
Economic crops (not essential for daily life) not needed 4 survival improve QoL
cotton, coffee, olive, fruit, sugar
Bioenergy crops- maize, groundnut, crop residues
- how can we use agricultural measurement to improve H20 resource usage
Bioenergy compatible to food crops if cultivate can solve energy crisis BUT how about food crisis
Will consume all fossil fuels within the next 50-100 years
we can extract and use bioenergy crops as fuels/energy support growing needs energy.
Factors determining crop distribution
4 main concepts
Population
Development level
Water resources and other environmental factors
Politics
Think about the future
The impacts of climate change on global food production
Why?
North America
South America
Europe
Africa
limited area cultivation for crops- have two decide which one to grow over other ones what determines the production of these crops?
1) China big population need lots of food to survive
2) different ways to make crops- improve food quality
What is behind crop products?
How much water do you consume every day?
What is behind crop products?
3,500 litres of water is used every day by people in Britain
Only 150 litres is wthin the home, the rest is 'hidden; in foods and goods consumed.
Two factors affect virtual water behind crops
* Crop type
* Agricultural management
Virtual water trading
one hamburger - 2400 litres
one glass of milk- 200 litres
one cup of tea - 35 litres
Fruit Spain, meat - ^_^
Virtual water trading
People think global trading is only about food actually global trade- water resources- water fixed lakes and rivers - import oil through Nigeria
Water traded through food crops - reevaluate how much water we have imported
Differet countries and how gloval trading of H2O affects development agricultural sectors in different countries
Global food crops distribution
Global distribution of food - 4 types of food
China no space for you to travel - 1.5 billion people in China eat good- grow as many as they can
Europe- no rice grows here, rice imported from eastern Asian countries China & India
Economic crops
Temperate region
fruit, olive
Subtropical region - sun
cotton, herbs - raain
Tropical region
sugar, cocoa, cotton - huge amount of sunlight
1) Temperature
2) Politics <- economic crops not UK - we're trying to put production in developing countries- history of global trading.
Most developed countries don't want agricultural production in their country - uses a lot of resources, damages ecosystem
Global trading of economic crops
China, India imports importants
Coffee- S America, S.Asia
water resource
African countries- limited H2O yet still growing economic crops because need £££
Have to grow economic crops sell developed countries support society
Bioenergy crops (graph)
Three generations of biofuels
Bioenergy crops (graph)
Problems occupy landscape
Cultivate bioenergy OR food crops - Hard choice
Can use bacteria/algae photosynthesis - cells
Extract oil - burn - cO2 - released again
utilise environment microbes increase biofuel/bioenergy
energy crisis - different KJ crops instead of what is buried underneath
first generation crops - food was unsustainable - low Kj contamination
agricultural residue - create bioethanol - good way harvest Kj
blocked carbon cycle throughout process- not returned to soil- soil has less nutrients, need more fertilisers to support production.
Cultivate crops huge amount kJ - oils from those things burn oils instead of residues
Environmental concerns table
Global freshwater availability
Lack of H2O in N.Africa, India and China
Bioenergy crops competition with food crops
Virtual water trading
Bioenergy crops consume more H2O than food crops
Gloal water exchane- some countries lack H2O
Green = countries net natural water export- water exported other countries
Red = importing water - other countries
Virtual water trading with bioenergy crops
Further develop bioenergy crops this situation worse
< Virtual water exported from Africa to Europe & China
Virtual water trading
Internally virtual water utilisation
Red- virtual water dependent countries
If you don't trade global agricultural products- the UK won't survive
Possible solutions?
Agriculture management - modern ways irrigation system reduce virtual water Developing countries - traditional methods use more water.
Agricultural management reduces the virtual water in global trading
Local people improve H2O efficiency
Fairtrade
Agriculture management
Conventional agriculture
Traditional way:
- Less efficient
- Lots of water consumed
- Takes a long time
Agriculture management
Modern agriculture
Machines - seed, harvest, treat plants
Water measurement, supply as many as you need to reduce virtual water within plants
Only supply the water they need
Agriculture management
Topography
- Some countries don't want to use modern techniques
Agriculture management
Topography
Water resources
Trational veg need to cultivate plants in mountain area
Modern agriculture - huge amount of water reservoir need to maintain areas - fixed area- supply stable water in eastern Asian areas- water not sustainable in the summer - too little
winter too much
no fixed area to supply water
Agriculture management
Labour cost
- Majority of people use hands to grow plants
- Machines- give peopl jobs but not enough food resources
- More people in India/China trying to find a job in Europe
- - Job security lost machinery
Agriculture management
Economics
need money to buy facilities
need oil feed
technicians - maintain utilisation/fix
technical training

FairTrade
Fairtrade cuts out the middleman meaning more profit goes to the farmer.
Fair Trade is a partnership built on a network of relationships that respect people, promote fair business practices, and protect the planets
Coffee beans cultivated local population
middle people play more, higher £££
fair trade trying to reduce profits the middle people make by giving more money to local people
More money spent techniqus- local people- improve facilities, reducing H2O consumption, improve ecosystem & QoL - fairtrade
Action needed
1 billion hungry - should save the food you have, reduce unnecessary exchange global food
1 baby dies every 8 seconds- Africa
one billion hungry don't have sufficient food
1/3 food wasted <- thrown in bin- should improve efficiency food products, lots of virtual water H2O developing countries
- Soil diversity
- Agriculture input fertilizer and pesticide
- Crop output (nutrition)
- Water management
- Policy support
- Climate change
- Ecology
Growing planet - populatio growing plants
We need help agricultural countries improve agricultural methods
care about waste
Cultivate the planet in sustainable mode

Beddington et al 2009
intrinsic link between challenge we face ensure 21stC food security and other global issues - climate change, population growth & need sustainably manage world's rapidly growing demand for kJ & H2O.
predicted by 2030 world will need to produce 50% more food and energy whilst mitigating and adapting to climate change
we need a 'greener revolution'
meeeting demand for energy whilst mitigating and adapting climate change requires mix behavioural change and technological solutions.
global population set to increase to around 9 billion by mid century
rising at rate 6million people mer month
energy demand projected to incrase 45% by 2030
biofuels for transport and biomass for heat and electricty used meet some demand- greater competition for land & crops.
Beddington et al 2009
TODAY 1.2 billion people live in areas already affected by water scarcity- figure will increase as global water demand rises.
agriculture largest user water world-wide - 70% total supplies
agricultural sector will need to compete - world's growing cities- H2O
thus unlikely water remain 'free' commodity future
challenge for global agriculture grow more food on similar land on similar land area using less water, fertiliser and pesticides than we have historically done.
climate change
these demands must be met rising global temperatures, impacting on water, food and ecosystems in all regions. more severe and frequent extreme weather events.
need to mitigate climate change & adapt to that which cannot be avoided is clear.
been suggested that global green house gas emissions must be reduced by 50-60% by 2050 compared to current levels.
Beddington et al 2009
it is predicted by 2030 world will need to produce around 50% more food & energy
can 9 billion people be fed equitaby, healthily and sustainably?
can we cope future demands on water
ingram et al
Climate change may affect food systems in several ways ranging from direct effects on crop production (e.g. changes in rainfall leading to drought or flooding, or warmer or cooler temperatures leading to changes in the length of growing season), to changes in markets, food prices and supply chain infrastructure. The relative importance of climate change for food security differs between region
southern Africa, climate most frequently cited drivers of food insecurity because it acts both as an underlying, ongoing issue and as a short-lived shock
2000, the member states of the United Nations committed themselves to eight Millennium Develop- ment Goals
mate change is only one of several changes affecting food systems and that its relative importance varies both between regions and between different societal groups within a region

(Pingali & Khawaja 2004)
In south Asia, studies have examined how income growth has led to changes in diets away from traditional foods. This may have negative impacts on local farmers who grow traditional foods and are not well integrated into markets (Pingali & Khawaja 2004)
n, resource- conserving technologies restrict the oxidation of soil carbon thus mitigating increases of CO2 into the atmosphere
environmental feedbacks
s The possible environmental impacts of adaptations include:
(i) changes in biodiversity due to extension of the agricultural frontier;
(ii) water pollution associated with increased use of fertilizers and pesticides;
(iii) waterlogging, salinization and water scarcity due to irrigation and
Eating on an interconnected planet
Macdonald and Graham 2013
calls to boot agricultural product to meet demands growing population - common
international trade could be v necessary in trasnferinf food from farm to consumers
importing crops may be one out of necessity if available land and H20 limits production
relatively small number of countries prduce bulk of staple crops for global markets
Fader et al's study domestic crop production could theoretically replace imports & allow food self-sufficiency - many countries
Extreme scenario no yield improvements, no agricultural expansion & high population growth lates- roughly half of the global population would be import dependent by 2050.
