Agricultural Engineering
  • AGRICULTURAL MACHINES EVOLUTION IN A CHANGING
    WORLD

2
INTRODUCTION
We are in a changing world. And the changes,
even in far distant areas, are more and more
correlated (globalization effect). So we will
focus today mainly on Europe (now extended to 27
member states), but we cannot lose contact with
the rest of the world. What is relevant to
observe is that a lot of apparently independent
changes are causing economic, environmental and
social trends with combined relevant effects on
the evolution of agricultural machines.
3
BASIC STATISTICS
Our world is rapidly changing. The continuous
evolution of society, economy, technology and
culture is under our eyes, and if we give a
closer look to some statistic key indicators we
can better understand the size and direction of
change.
  • Demographics
  • Agricultural labor force
  • Cultivated land
  • Organic land
  • Farm size evolution
  • Climate change and precipitations evolution
  • Gross Domestic Product
  • Agriculture value
  • Commodity prices
  • Agricultural income
  • Bio-fuels

Statistics Population
Europe has 7.5 of the world population and it is
about two times the USA population but it is
much smaller than both India and China.
5
Statistics Demographics
The effect of Europe net migration will no longer
outweigh the natural decrease after 2025, when
the population will start to decline gradually.
The worldwide population of the least developed
areas will pass from 5,4 billion to 7,9 billion
in 2050 while the developed areas will remain
stabilized around 1,2 billion. They would undergo
a decline normally if one did not take in account
the migration of the developing countries towards
the developed countries
6
Statistics Demographics
While the European population is substantially
not growing, China, India and the USA populations
are growing around or more than 1 per year.
7
Statistics Demographics
  • All European countries population evolution
    by age groups

Europe has grown so far only due to the addition
of new state members (from Europe-12 to
Europe-27). The European lack of population
growth is also pictured here where the main age
group trends are shown.

Statistics Rural Population
The percentage of rural population is wide
ranging and its decreasing everywere
9
Statistics Agricultural Labor Force
Over the period 1995-2000, the agricultural labor
input has declined by 2.0 p.a. in the EU15.
This rate of change has speeded up since 2000 to
-2.3 for the period up to 2005 (EU25 -2.5)

Statistics Cultivated Land
  • Over ¾ of the territory of the European Union is
    agricultural (42) or wooded land

Statistics Organic Land
The total organic area in the EU15 increased from
2.3 million hectares in 1998 to 4.9 million
hectares in 2002. The organic farming area
reached 3.8 of the total Utilised Agricultural
Area (UAA) of the EU15 in 2002, up from 1.8 in
1998 Worldwide (2006) approx. 31 million of
hectares are grown organically

Statistics Climate Change
Future impact on summer temperature (C) of
climate change simulated within the scenario
GIEC-B2. The small red squares correspond to a
temperature increase between 3 and 4 C
This climate simulation model (ARPEGE-Climat) for
the years 2070-2100 is not a real forecast but it
shows what could be possible if the radiation
active gases concentration will increase
according to the model hypothesis

14
Statistics Precipitations Evolution
Difference between the winter precipitations in
the period 2070-2099 and the ones in the period
1960-1989. Figures a and b are related to two
simulations of the period 2070-2099 versus the
period 1960-1989, made with the model
ARPEGE-Climat, different only by the initial
conditions assumptions. The scale is in mm/day.
The trend on both simulations shows an increase
in winter rainfalls over Europe and a decrease
over the Mediterranean see and the Northen
Africa. The figures c and d correspond to the
figures a and b and show the same trends for the
summer rainfalls.

Statistics Gross Domestic Product
17
Statistics Agriculture value
  • According to the EAA the output value at producer
    prices (the producer prices excludes subsidies
    less taxes on the products) of the agricultural
    industry is 292 billion in 2005 for the EU25

18
Statistics Commodity prices
  • All the institutions are predicting significantly
    higher prices for the next 10 years
  • than over the past decade.
  • The projections are subject to many
    uncertainties assumptions about productivity
    growth, risks of sanitary and phyto-sanitary
    crises, climate change, the weather, etc.

19
Statistics Europe Agricultural Income
EU27 real agricultural income per worker rose by
5.4 in 2007, after increasing by 3.3 in 2006.
This increase was the result of a growth in real
agricultural income (3.1) and a reduction in
agricultural labour input (-2.2).
20
Statistics Biofuel
Current biofuel technologies
Source IFP
  • The use of vegetable oils as engine fuels may
    seem insignificant today but the such oils may
    become, in the course of time, as important as
    petroleum and the coal tar products of the
    present time.
  • Rudolph Diesel, 1912

21
Statistics Biofuel
  • EU Directives targets
  • - Current 2 of biofuel
  • - by 2010 5.75 of biofuel
  • - by 2015 8 of biofuel
  • - by 2020 10 of petrol and diesel to be replaced
    by biofuels (20 of energy consumption coming
    from renewable sources)
  • In 2005, 2.6 million hectares in Europe were
    occupied by energy crops used to produce
    biofuels 2.4 million hectares of crops to
    produce biodiesel (95 rape, 5 sunflower) and
    0.2 million hectares of crops to produce
    bioethanol (49 wheat, 51 sugar beets)
  • In 2005, Europe consumed about 4.2 Mt of
    biofuels, equivalent to 1.2 of road transport
    fuel consumption. The European Union did not
    attain its target biofuel content of 2 - which
    represents 5.8 Mtoe of biofuels.
  • By 2010 the target is 16.6 Mtoe, which would
    require about 82 Mt of farm biomass and a land
    area of about 13.8 Mha. To meet this demand for
    biofuel, it would be necessary to allocate a land
    area for rape alone larger than the cumulated
    area of all fallow land in Europe (approx. 8.2
    Mha), knowing that not all of these lands are
    cultivable.

22
GENERAL TRENDS
From all these data we can observe, inside the
change, some clearly emerging trends
  • Agricultural workforce decrease / average age
    increase
  • Farm size increase
  • more complex farm management
  • Regulations evolution
  • safety / health protection
  • environment / pollution reduction
  • Productivity / precision increase
  • Bio-fuel / Bio-mass production increase
  • Water shortages
  • Organic cultivation expansion

23
Population decrease / average age increase
  • Agricultural workforce decrease (combined effect
    of European population slight reduction and
    decreasing agricultural percentage of the
    population).
  • Average age of people working in agricultural
    areas is increasing and this drives a strong
    request for equipment ergonomic, ease of use,
    low-effort controls, highly automatic operation
    sequences, safe drive.
  • Agricultural income positive trend, in conditions
    of workforce decrease, implies a significant
    productivity increase.

24
Farm size increase
  • The progressive increase of farm size implies a
    general complexity increase in the farm activity
    management (more crops, more machines, more
    workers).
  • The enterprise risk also increases and more
    management skills and tools are required
    (business approach, accurate accounting,
    cultivation and crops planning, fleet management,
    maintenance programs, purchase of services,
    etc.).
  • The farm economic development implies a
    continuous search for productivity and
    efficiency, which means more machines and more
    productive machines.

25
Productivity / precision increase
  • The demand for higher productivity on all farm
    operations is constant
  • efficient machines
  • high speed operations
  • bigger machines, higher power
  • automatic operations
  • ease of use
  • comfort
  • Precision in farm operations is also an
    increasing priority, because it usually increases
    the efficiency in the use of machines and
    materials (seeds, water, fertilizers, etc.).

26
Bio-fuel / Bio-mass production increase
  • The limited availability of fossil fuels and the
    rapidly increasing oil prices are driving a
    strong interest on bio-fuels
  • Both in the USA and Europe the spontaneous
    extension of bio-fuel crops is supported by
    dedicated governments plans.The European target
    to have by 2020 10 of petrol and diesel to be
    replaced by bio-fuels is going in this
    direction and probably more specific support to
    the bio-fuels crops will come.
  • The fight for low cost bio-fuel will drive even
    more the productivity of these cultivations and
    of the machines used for that, seen that the
    available land is limited.
  • Bio-fuel will require wider fields for energy
    crops, and farmers will require bigger machines,
    with more hp, and bigger implements.

27
Water shortages
  • The climate changes are difficult to forecast,
    but there is a general consensus among scientists
    that the global warming is a real process and
    that significant modifications will happen in the
    next decades.
  • The main consequences of global warming will be a
    change in precipitation pattern (probably some
    increase of precipitations in Northern Europe and
    a decrease of precipitations in Central and
    Southern Europe).
  • Therefore the availability of water for
    irrigation will change significantly, driving
    changes in the mix of cultivations.
  • The demand for water will also increase
    dramatically in the rest of world, with the
    increase of irrigated land needs.

28
Organic cultivation expansion
  • In Europe the land cultivated organically is
    roughly doubling every two years, leading to a
    significant business impact in the agricultural
    world.
  • The choice of non-OGM crops, the very limited use
    of pesticides and herbicides and the use of
    accurate cultivation methods is driving a
    significant use of specialised machine work, but
    with needs of clean machines, with low
    emissions and high prevention of land and crop
    contamination (e.g. oil drops).
  • This also leads to high value agricultural
    production, sustained by prices higher than
    average but with demand for high quality process.

29
Regulations evolution
Another important trend in Europe, and in many
other countries, is the rapid evolution of
regulations. This is a direct consequence of the
social and political evolution, with increased
sensitivity to population and workers health and
safety. Air pollution and gas and particles
emissions are already strictly regulated and they
will be more. EEC legislation on agricultural
machines is quite complex and subject to
significant evolution. - machines need to
comply with a long list of EU directives -
homologation is gradually replaced by
self-certification
30
Regulations evolution
  • Typical examples where regulation has a
    significant impact on the product design
  • Health and safety
  • Roll over protection (ROPS), falling objects
    (FOPS)
  • Hazardous substances
  • Air purifying devices, to limit operator exposure
    to hazardous substances (tractors, sprayers)
  • Protection of passenger
  • Seat belts anchorages and location and mounting
    of passenger seat
  • Social or horizontal Directives, intended to
    cover the risks in the work sites.
  • Exposure of workers to the risks arising from
    physical agents (vibration)
  • Compliance with these regulations is in charge of
    the employer but, obviously, becomes a task for
    the manufacturer.
  • Road transport
  • Drive by noise
  • Vehicle width, axle weights and signalisation
  • Increased road speed, braking performance
  • EMC (electromagnetic emission)
  • Engine emissions

31
Engines Emissions Targets
  • Since 2000, there has been a continuous reduction
    of particulate and NOx emission levels
  • From Tier 4 onwards exhaust after-treatment
    devices will be required

GENERAL TRENDS DRIVE MACHINE EVOLUTION
  • All the trends we have seen so far have a
    powerful drive into the evolution of agricultural
    machines.
  • The combined effect of these drivers and the
    evolution of technologies will cause rapid
    changes and new offering in the machines
    scenario.
  • The main evolution directions can be summarized
    as follows
  • Bigger equipment / higher power
  • Emissionised engines / clean machines / use of
    bio-fuels
  • Safe work environment
  • Higher speed
  • Serviceability / maintainability improvement
  • Precision farming / Auto-guidance
  • Automation / CVT transmissions / electronics /
    interaction with implements
  • Specialized products / highly configurable
    products

35
Bigger equipment / Higher power
  • Larger fields, less manpower, demand for higher
    productivity will continue driving up equipment
    size and power.
  • Larger implements will then require more pulling
    and controlling power.
  • The endless power up trend will continue.

36
Emissionised engines / Clean machines / Use of
bio-fuels
  • The future agricultural machines will be more and
    more respectful of the environment.The engine
    emissions regulations, already quite severe, will
    continue to follow the big push for further
    reduction, even in the emerging economies like
    India and China.
  • The global push to save the environment and
    respect the nature will drive our machines to
    become always greener and cleaner.
  • The use of bio-fuels and all sort of alternative
    fuels will increase significantly. Users and
    dealers must become familiar with the storage,
    handling and use of bio-fuels.

37
Safe work environment
  • The agricultural machine is often seen as a
    working environment, where the operator stays for
    many hours a day and where he does a lot of work
    operations.European and North American
    legislations are very focused on guaranteeing
    safety and healthy working conditions.
  • This means not only safe equipment and low levels
    of noise, vibration, air pollution, but also ease
    of use and comfort.
  • Instructions must be clear and exhaustive
  • Controls must be easily reachable and immediate
    to understand and use. Signals and warnings have
    to cover all the significant potential risks.

38
Higher speed
  • Even if the European legislation is a little bit
    behind, the tractors speed desired by users is
    often higher than 40 km/h.
  • 50 Km/h is becoming normal in many countries
    (recently including the USA) and 60 km/h or more
    is the next step.
  • Improved braking systems and axle suspensions
    will be more and more required for a safe high
    speed drive. And the same applies to trailers and
    other towed machines.
  • But speed is also required in many other machine
    operations, because it means productivity so it
    will become a constant trend for complete
    vehicles and for specific operations.

39
Serviceability / maintainability improvement
  • The social progress, the evolution of comfort
    perception and quality of life and the ageing of
    population will all lead a demand for better
    machine serviceability.
  • Customers want to service their machines less
    times and in an easy and safe way.
  • They want to access to all the relevant parts of
    the equipment without risk or fatigue and easily
    check the need for maintenance, in this supported
    by clear on-board diagnosis.
  • Maintenance has to be easily planned and all the
    service operations must be very simplified.

40
Precision farming / Auto-guidance
  • The adoption of precision farming techniques is
    one of the most effective ways to increase the
    yield and productivity of the agricultural land.
  • Satellite maps, ground and crop analysis, yield
    history, culture optimization planning are now
    possible with the help of services and equipment
    available in the market place.And the use of
    these tools is proving to be very effective in
    farm operations improvement.
  • Auto-guidance systems will more and more drive
    with precision the machines on the ideal paths,
    to minimize errors and redundancies in field
    operations, pulling increasingly sophisticated
    large implements.

41
Automation / CVT transmissions / electronics /
interaction withimplements
  • The demand for productivity, ease of use and
    field operations improvements will drive even
    more the already exploding rate of electronic
    and automatic devices on agricultural machines.
  • Continuous Variable Transmissions will grow at a
    very high rate and electronics will become the
    technology mostly spread around in our machines.
  • Electronic bus technology, based on existing
    standards (CAN-bus, ISO-bus) and on new ones,
    will transform the machines in complex integrated
    systems, more and more intelligent and with
    extended capabilities to communicate each other
    and with implements and attachments.

42
Look at this combine
43
Or at this tractor driveline
44
And the driver will no more be required
  • The rapid evolution of the machine capabilities
    will exceed the human expertise in the
    agricultural domain and the machines will act
    autonomously, fully robotized.
  • Examples will be
  • machine to machine optimal settings - copying
  • coordination of machine / machine activity
  • fleet management (coordinating the operation
    between all machines on the field for time and
    efficiency gain)
  • Up to the full drone machine, working without any
    operator on board and fully capable of
    self-regulating and adapting to the field work,
    taking instructions from remote computers and
    operators.

45
Specialized products / highly configurable
products
  • In addition to the technology evolution, the
    agricultural machines will also become more
    specialized, to optimize their use in the various
    conditions and cultivations.
  • This will follow a two-fold path
  • true machine specialization, with specific
    devices and features for a particular set of
    operations
  • high configurability of generic machines, through
    options and dealer installed accessories, to
    adapt them to special work and conditions.

46
Engineers Are Key Game Players
  • Mechanical and agricultural engineers are key
    game players in this evolving natural, social and
    technological scenario.
  • Our best efforts should be devoted to
  • - understand general change trends and
    anticipate farmers and social needs
  • - continue pursuing innovation, not only on
    technology
  • - identify new or specific needs of groups of
    people in agriculture
  • - identify new product functions
  • - develop new ways to provide functions.
  • Knowledge, skills and innovation attitude are
    needed qualities, to surf the wave of change and
    shape the future of our agricultural world.
