The Agricultural World (Parts 1 4)

Antoine Vella 1

Antoine Vella 2
All humans depend on agriculture for foodand urbanised,
industrialisedsocieties depend onfood surplus generated by
farmers. We could say that without agriculture there could be no
civilisation.

Antoine Vella 3
Agricultureis the principal enterprise of
humankind through most of recorded history.
Today it remains the most important economic
activity in the worldemploys45% of the working
population.
This figure varies from 3% in
some European countries to
over 80 % ofthe labourforce in
parts of Africa and Asia.

Antoine Vella 4
There are innumerable types of
agriculture practised around the
world. In most regions one can find
different forms existing together but
there are predominant types in
certain parts of the world.

methodswhich are typical of that region.

Antoine Vella 6
By studying the
different forms of
agriculture we can
find out more
about the
environmental and
cultural characters
of that region.
Each region is therefore distinguished by a predominant
type of farming.

Antoine Vella 16
We shall now look at the various types of agriculture as
practisedin today’s world. First of all we may divide the
world regions into:
•Developing
•Developed

Antoine Vella 17
Agriculture may also be divided into;
•Subsistence
•Commercial

Antoine Vella 18
Basically this is when the farmer (or the local farming
community) produces in order to satisfy their own material
need with little
or no surplus
so that there is
limited external
commerce.

Antoine Vella 19
Farmer do not produce all that they need but grow “cash
crops” or other products which are sold, sometimes to
buyers long distances away. The farmer is thus more
integrated within the modern market economy.
This is usually a more
specialised form of
agriculture and found
especially in developed
countries.

Antoine Vella 20
In developing regions agriculture may be:
•Nomadic
•Sedentary
Most of farming in
developing countries is
of subsistence type but
we may also find some
traditional examples of
commercial agriculture.

Antoine Vella 21
This is a form of agriculture and lifestyle that is gradually
disappearing but can still be found in many areas around
the world.
There are two main
forms here:
•Nomadic pastoralism
•Shifting agriculture

Antoine Vella 22
This is an relatively intensive form of field cultivation. It
may be based on rice or other crops

Antoine Vella 23
In developing countries there is
only one type of such agriculture
that is widespread:
•Plantations

Antoine Vella 24
In developed countries agriculture is typically commercial
and divided into
•Crop husbandry
•Animal husbandry
•Mixed farming
There are also other
special types (e.g.
Mediterranean) which
will be treated later.

Antoine Vella 25
Farmers work fields, often using extensive mechanisation
to produce plants for the market.

Antoine Vella 26
In this case the farm income comes from the production
and sale of animal products.

Antoine Vella 27
This is usually
a traditional
form of
agriculture
based on
smallholdings
and family
farms.

Nomadic agriculture is based on animal or crop production
and divided into nomadic pastoralism or shifting
cultivation.
As explained, here we have
farming which is:
subsistence or commercial.
Subsistence may be further
subdivided into:
nomadic or sedentary.

Herdingis the practice of
bringing individual animals
together into a group (herd or
flock) and rearing them as a
group. It was the first form of
‘agriculture’ developed by
humans and preceded arable
farming (that is, the growing
of plants).

Antoine Vella 34
The first herders were nomads
because their animals depended
exclusively on grazing and the
herds had to be moved in order to
allow the pastures to recover.
Above: Sahel Below: Lapland Right: Tibet

Antoine Vella 35
Nomadsmove from place to place, rather than settling down
in one location. Today there are about 30-40 million worldwide.
Nomads in
northern India

Antoine Vella 36
At some point of their history, most cultures have passed
through such a phase and, for some this is still a tradition.
There are three kinds of nomads:
•hunter-gatherers,
•pastoral nomads,
•peripatetic nomads*(gypsies)
*Normally not
engaged in agriculture

Antoine Vella 37

Antoine Vella 38
Nomadichunter-gatherers have by far the longest-lived
subsistence method in human history, following seasonally
available wild plants and game.
Bushmen of
Northeast Namibia.

Antoine Vella 39
Pastoralistsraise herds
and move with them so as
not to deplete pasture
beyond recovery in any one
area. The term ‘Nomadic
Herding’ refers to these
cultures.

Antoine Vella 40
Nomads in Sub-Saharan Africa are the only
ones who depend mainly on cattle.
Further north, dromedaries, sheep and goats
are more important. nomads depend on
dromedaries, sheep and goats.

Antoine Vella 41
Nomads living in the tundrasof northern
Eurasia raise reindeer while those of
central Asia keep camels, horses, yak,
and sheep. In W. Asia nomads depend
on dromedaries, sheep and goats.

Antoine Vella 46
Nomadic herders rear cattle, sheep, goats, horses and
camels. Some migrate from lowlands in winter to mountains
in summer. Others shift from desert areas in winter to
adjacent semiarid plains in summer

Antoine Vella 48
As we’ll see later in Shifting Cultivation, Nomadic Herding
also risks becoming unsustainable in many areas.
As animals and
human populations
increase,
overgrazing and
deforestation
intensify with
desertification the
end result.

Antoine Vella 55
Many nomads continue to follow age-old traditions and travel along
ancient routes. These were often established long ago, before modern
states were formed and nomads often find their way blocked by national
borders. This creates a problem for them and, sometimes for the various
countries through which they travel.
The shaded area is the ancestral territory
of the Tuareg, now spanning 6 countries

Antoine Vella 56
The territories inhabited by ethnic groups often do not
correspond to the national frontiers which have developed
over time.
Since the Middle Ages, the
place Mongols originated
has been divided various
times. At present, the
southern half is part of China
while the northern section is
an independent State.

Antoine Vella 57
Today, nomadic herding is
almost everywhere in decline.
Governments have policies
encouraging nomads to become
sedentary.
This process was started in the
19th century by British and
French colonial administrators
in North Africa and later
adopted by Russiain its Asian
territories.

Antoine Vella 58
In the Middle East, many nomads are voluntarily abandoning
traditional life to seek jobs in urban areas or oil fields.
Severe droughts in
Sub-Saharan Africa
has caused many to
abandon nomadism

Antoine Vella 59
Today, nomadism survives mainly in remote areas, and
may soon completely vanish.

Antoine Vella 60
This is a form of pastoralism traditionally organized around
the migration of livestock between mountain pastures in
summer and
descend to
relatively warm
areas in the valleys,
foothills or plains in
winter.

Antoine Vella 61
Sometimes the seasonal migration may between lower and
upper latitudes (as in the movement of Siberian reindeer
between the subarctic taiga and the Arctic tundra) is also
known by this name.
Only herds,and the
herders necessary to
tend them,travelwith
the herds.

Antoine Vella 64
Although, in this section, we’re considering developing
countries, transhumance can also be found in certain
Transhumance of sheep in the
Dolomites (Belluno)
regions of developed
countries.
For the sake of
convenience sake
we’ll describe this
type of farming here.

Antoine Vella 65
Traditional transhumance,
occurs throughout the world,
including European
mountainous regions (Alps,
Scandinavia, Balkans, Italy)
as well as India and parts of
Africa.

Antoine Vella 66
In Europe this type of agriculture is typical of the
Mediterranean, Balkan and Scandinavian highland regions.

Antoine Vella 67
The annual spring Transhumance Festival in Provence. The festival
commemorates the annual migration of flocks to different pastures,
and over 3,000 sheep are herded through the streets.

Antoine Vella 72
Reindeer transhumance -Finland

Antoine Vella 73
Transhumance is based on a climate difference between
mountains (where herds stay during summer) and lowlands
(where they remain in winter). Its importance to pastoralist
societies cannot be overstated.

Antoine Vella 74
Milk, butter and cheese —dairy products of transhumance
—often form a basis for a local population's diet.

Antoine Vella 75
The Sami (aka Lapps) live in northern Norway, Sweden and Finland, with
some groups also found in the Russian Kola peninsula.

Antoine Vella 76
Reindeer husbandry has been,
and is, an important aspect of
Sámi culture in Northern
Scandinavia.

Antoine Vella 77
During the years of forced assimilation, (esp. in the USSR)
the areas in which reindeer herding was an important
livelihood were among the few where the Sámi culture and
language survived.

This is essentiallya land rotation system. Instead or
rotating crops, the land itself is rotated. Probably arose
from a nomadic lifestyle.
Practisedespecially in less developed parts of the
tropical world where nature can quickly re-establish its
balance and recover from damage.
•Central and S. America
•Africa
•Southeast Asia
•Indonesia

Antoine Vella 81

Antoine Vella 82
Small patches of land are cleared by chopping vegetation
and girdling trees. When the vegetation has dried, it is
burned.
Thistechnique givesshifting
agriculture the common name
“slash-and-burn”.
Afterwards, usingdigging
sticks or hoes, farmers plant a
variety of crops in the
clearings.

Antoine Vella 83

Antoine Vella 84

Antoine Vella 85
In an ideal case, shifting cultivation would bea cycle where
farmers came back to the original place after a couple of
years. The picture shows a newly prepared land (known as
swidden) in the centre.

Antoine Vella 86
In the background is untouched forest, while the piece of land in
the foreground has been left idle from the previous cropping
cycle to re-grow into a secondary forest. On the right secondary
growth awaiting cultivation during the next cropping cycle.

Antoine Vella 87
This “slash-and’burn” plot is in the Ruwenzoris(Mountains of
the Moon). A burgeoning population does not permit a
suitable fallow period; crop yields are poor and the forest
never recovers.

Antoine Vella 88
Shifting cultivation by too many people is responsible for
tropical rainforest destruction over a vast area. Intercropping
is practiced with bananas, taro, cassava, beans and sorghum
being planted in the same field.

Antoine Vella 89
Shifting agriculture, as practisedin tropical areas,has a
harmful effect on the soil. In these areas there is an
excess of precipitation over evaporation, resulting in a
net downward movement of moisture through the soil.
Soil nutrients are
leached from the
soil, leaving
behind an acidic
and infertile soil
that is often
reddish in colour.

Antoine Vella 90
Why slash-and-burn farming is no longer sustainable
Improved health conditions have caused population growth
beyond the size supportable by this kind of farming
Swiddenfields in Vietnam reaching up to
the top of the hills
As people pass to the
second stage of
demographic
transformation the
periods during which
land is allowed to
remain fallow have
shortened and
environmental
deterioration is caused.

Antoine Vella 91
Nature protection which respects traditional culture of ethnic
communities tends to replace the shifting farming systems by
permanent, often tree-based agro-forestry schemes.
It must by all means
be prevented that the
swiddenfields
extend to the upper
ridges of the hills as
their the forest cover
is vital to retain
ecosystem functions
and services.

Antoine Vella 92
Shifting cultivation is also
carried out in some parts of
Germany but mostly by
amateur farmers who cultivate
land as a hobby.
In this case it is not a slash-
and-burn type of farming. In
Germany, most forest areas
are protected anyway.

world these are provided by starch produced by plants.
In some regions,
starch is provided
by potatoes or

the most part,
cereals are the
mainstay of
human life all over
the world.

Antoine Vella 97

Antoine Vella 98
Thisis a method of farming in which farmers plan to grow
only enough food to feed the family farming, pay taxes or
feudal dues, and perhaps provide a small marketable
surplus.
The Basotho people
rely on subsistence
agriculture for survival.
Animals raised by
Lesotho farmers include
cattle, donkeys,
chickens, pigs, dogs,
and sheep.

Antoine Vella 99
Subsistence agriculture usually refers to a farm that
produces enough to feed the family but not enough surplus
to participate extensively in the cash market.

Antoine Vella 100
The typical subsistence farm
has the range of crops and
animals needed by the family
to eat during the year.
Planting decisions are made
according to what the family
will need during the coming
year, rather than market
prices.

Antoine Vella 101
It is practisedworldwide and represents the first stages of
sedentary agriculture.
It may be primitive and simple
or more advanced but the
principle is always that almost
everything needed is
produced in the immediate
vicinity of the farm.

Antoine Vella 102
Subsistence agriculture
(predominantly growing
wheat and barley) first
emerged during the
Neolithic era when
humans started to settle
in the Nile, Euphrates,
and Indus River Valleys.
Subsistence horticulture
(growing vegetables)
may have developed
earlier in South East
Asia and Papua New
Guinea.

Antoine Vella 103
It was the dominant mode of production in the theworld
until very recently when market-based capitalism became
important.

Antoine Vella 104
Subsistence farming continues today in large parts of the
African interior and other areas of Asia and South America.

Antoine Vella 106
Subsistence agriculture was sustainable for millennia in the
absence of a population explosion.
Rural Fijians still practice
subsistence agriculture.
Some live in traditional
huts with woven mat
walls and thatched roofs.
Village life is communal,
with everyone expected
to share in ceremonial
preparations and village
upkeep.

Antoine Vella 107
Nowadays it is still practised
in a highland region more or
less equivalent to the old Inca
territories.
This region includes some of
South America's poorest
areas.
The farmers who carry out
this type of farming face
considerable environmental
challenges.

Antoine Vella 108
Subsistence agriculture
on small farm plots is
practiced in the highly
elevated Altiplanoof,
Ecuador, Peru, Bolivia
and northern Chile.
Farmers in the arid highlands must cope with the variable weather
conditions and extreme climatic uncertainty.

Antoine Vella 109
The economy in the Nepal
hills depends on subsistence
farming.
Peasants go to the southern
plains and India seeking
porter jobs for 4-8 months
each year to supplement their
incomes.

Antoine Vella 110
The money earned from non-
agricultural jobs is exchanged
with consumer goods e.g. salt
or sugar, or even a watch such
one of the farmers in the
picture is wearing. The oxen
available are too few for the
number of farm holdings. The
Monsoon-dependent farming
requires all fields to be
prepared almost all together -
not to own a pair of oxen
possibly means the farmer has
to find sources of energy.

Antoine Vella 111
In densely populated central Africa,
small subsistence plots cover the
once-forested hillsides.

This forms the basis of “plant

intake is of plant (mostly rice) origin.

Antoine Vella 115
A paddy field is a flooded field used for growing rice. Rice can
also be grown in dry-fields, but from the 20th century, paddy
field agriculture became the dominant form of cultivation.
Paddy fields are a
typical feature of rice-
growing countries of
Eastand Southeast
Asia but are also
found in other rice-
growing regions such
as Piedmont (Italy),
and the Camargue
(France).
Rice paddies in Bali

Antoine Vella 116
Rice is probably the most important grain
with regards to human nutrition and caloric
intake, providing more than 20%of the
calories consumed worldwide by humans.

Antoine Vella 117
Tiny, mud-dyked, flooded
rice fields, many perched
on terraced hillsides.
Paddies must be drained and rebuilt each
year. It requires much skill and experience
not only to build the paddies themselves
but also to regulate the water supply.

Antoine Vella 118
Rice does not need to grow in water throughout its entire cycle
but only in the first phase of its life.

Antoine Vella 119
The role of water is only to protect the young plants from rapid
temperature changes.

animal both in agriculture and
transport.

Antoine Vella 124
The buffalo lives in close contact with humans and is often considered as
a member of the family.
Above: Vietnam Right: India

Antoine Vella 125
Water buffaloes have been largely replaced by machinery
especially in Korea and Japan. This type of highly organised
and mechanisedagriculture can no longer be described as
subsistence but is a more commercial form of cash cropping.
(see later sections for discussion of commercial farming)

Antoine Vella 126

Antoine Vella 127
Most paddy rice farms outside the communist area of Asia are small. Small
patches are intensively tilled and large amounts of manure used.
Young rice sprouts are carefully transplanted by hand from seed beds to
paddy. The same parcel of land may be planted 2-3 times a year and yields
are very high –comparable to western ones.

Antoine Vella 128
There are significant adverse impacts from rice paddy
cultivation due to the generation of large quantities of methane
which is a greenhouse gas.

Antoine Vella 129
Rice is also grown in the Mediterranean, especially in the
Lombardy plain of N. Italy and, to a much less degree in the
Rhone delta in S.France.
Paddy fields in the
Camargue, Rhone delta
In Europe, rice-
growing is not
subsistence
farming and will
be considered
later in the
presentation.

Antoine Vella 130
Italy is the largest rice producer and exporter in the EU,
producing 70%of European rice.

Antoine Vella 131

Antoine Vella 132
World methane production due to rice paddies has been estimated in
the range of 50 -100 million tonnesyearly; this level of greenhouse gas
generation is a large component of the global warming threat and
derives simply from an expanding human population.

Antoine Vella 133
Genetic engineering has been carried out on rice in
Switzerland and Germany to produce a fortifiedfood for
areas where there is a shortage of vitamin A.

Antoine Vella 134
In 2005 a new variety called
Golden Rice 2 was announced
which produces up to 23 times
more Vit A than the original golden
rice.
Neither variety is currently
available for human consumption.

Cacao plantation in Colombia

Antoine Vella 139
A plantationis usually a large estate, especially in a tropical or
semitropical country, on which cash crops (especially tree or
bush crops) such as cacao, tea, coffee, sugar cane, banana
Coffee plantation in
Honduras
and rubber are
cultivated, usually by
workers who live on
the site itself.
Cropsare grown for
sale in distant
markets, rather than
for local
consumption.

Antoine Vella 140
The plantation system:
•Relies on large amounts of hand labour
•Originated in the 1400s on Portuguese-owned
islands of the coast of tropical West Africa
•Today, the greatest concentration is in the American
tropics.
•Most plantations lie on or near sea-coasts and
shipping lanes.
•Produce is carried to non-tropical lands —Europe,
United States and Japan.

Antoine Vella 141
A plantation is always a monoculture over a large area and,
because of its large size, takes advantage of economies of scale.

Antoine Vella 142
Most plantation workers live on the
plantation.
In the past slaves were relied on to
provide the labour
Because of the necessary capital
investment, corporations or
governments are usually owners
of plantations.

It should be noted that temperate
fruit crops, such as these cherry

considered plantations in the
classical sense.

associated with slavery, indentured labour, and exploitation.

Agriculture in developed countries is usually more
specialised than elsewhere and, as we have mentioned, we
can distinguish farmers who grow plants, those who rear
animals and
others –usually
smallholders –
who practise
mixed farming:
some crops and
some animals.

163
A smallholding is basically a farm of small size run by a
family with a small number (if any) hired hands.
In many parts of the Western
world they are being gradually
replaced by large industrial-
style holdings but their utility
has been recognised by the
EU and, in Europe, such
farms receive assistance to be
able to survive. All farms in
Malta are smallholdings.

164
Farmers in developed
countries depend on
machinery and modern
technology.

165
Without such
technology the
number of farmers
would have to be
much higher than
the 2-3% that it is
in Europe and
North America.

Cereals are plants belonging to the grass family and grown for
grain They provide carbohydrates (starch) and are the most
important –sometimes the only -source of energy for humans.
Wheat in flower –the elongated structures are stamens, producing
pollen.

170
The most important cereals are:
Maize Rice Wheat
Sorghum Barley Millet
Oats Rye
The top three account for almost 90%
of all grains produced worldwide and
provide more than 40% of calories for
human populations.

171
Barley Oats MilletSorghum

172
All cereals are annual plants and can be divided into:
Cool-Season: wheat, barley, oats, rye,
Warm-season: maize, rice, sorghum and millet
Barley and rye
are the hardiest
cereals, able to
overwinter in the
subarctic and
Siberia.

173
Cool-Season: wheat, barley,
oats, rye, triticale.
These are hardy plants that
grow well in moderate
weather and cease to grow
in hot weather

174
With an annual world production of 500-600 million tonnes,
wheat contributes between 10 and 20% of the daily caloric
intake of people in over 60 countries.

Maize (Zeamays) is a cereal grain from Central America. It
is called corn in the US, Canada and Australia, but in other.
countries that term

181
Maize is grown wherever summers are warm enough and
rainfall or water supply adequate.
It is important as
fodderand, in
developed
countries, the crop
is grown
specifically for this
purpose. The plant
may reach 2 to 4
metres.

As already noted, machines play an essential role in this
type of farming.

186
In many cases machines have taken over from human
workers and the number of farmers in developed countries
has decreased drastically.

187
Warm-season: maize, rice, sorghum and millet
These plants prefer warm humid climates and do not do
well in very cold weather.

188
Since cereals are essentially a type of grass, the best
regions to cultivate them are where grasslands constitute
the natural eco-system.

189

190
A grassland is a green, windy, partly-dry biome: a sea of
grass covering almost 25% of the Earth's land area. Deep-
rooted grasses dominate the flora with very few trees and
shrubs.

192
In nature, grasses often form a habitat that excludes most
other plants so that there are vast stretches of “grasslands”
which would be the
equivalent of the
agricultural
onoculture.

193
There are two types of grasslands according to their latitude:
Temperate Tropical

194

195

196
Biomes with hotsummers and cold winters. The
evaporation rate is high, so little rain makes it into the rich

201
Despite the fact that grasslands may be found both in
temperate and tropical regions, it is only in the former that
we find commercial grain-growing on an industrial scale.

202
This is a specialised form of very large-scale farming that is
really possible in areas with natural grasslands. It is also
feasible only where there is sufficient industrialisation and so
its development started in the prairie areas of N. America.

203
The possibility of having large storage capacities is also an
essential condition for the development of commercial
grain-farming.

204
Grain silos are a typical
sight in the landscape of
grain-growing regions
around the world.

205
Winter wheat starting to germinate -Colorado

206
Nowadays this form of agriculture is found in several other
areas of temperate grasslands in developed countries:
Canada, Australia, Russia, Ukraine and Argentina.

207
In developed countries but
especially in the US and Canada,
grain-growing is associated with
large corporations which control
vast rural areas and trade the
produce as an international
commodity.
The traditional family farm is no
longer of much importance and
being replaced in this sector.

208
In particular in the US, grain
farming has become so
specialised and mechanised
that the “farmer” does not work
the land but only takes
managerialdecisions and then
contracts specialist firms to do
the actual work in the field.

209
This is known in America as “suitcase farming”and in Malta
we have a similar situation, albeit on an infinitely smaller
scale.

210

211

212
As in North America, agriculture in much of Western
Europe is really agribusiness. This includes widespread
use of machinery and hybrid seeds
Wheat field in Basilicata. S. Italy

213
Besides the ‘real’ grains belonging to the cereal family,
soya (a legume like beans) is also nowadays considered as
a crop typical of grain-farming.

214

215
Fodder crops are plants that
are grown to feed animals,
especially ruminants and
horses.
The term refers particularly
to plants cut and carried to
the animals, rather than food
which they forage for
themselves.
Fodder includes hay, straw
and other variously
processed plant products.

216
There are two main groups
of such plants, belonging to
two different botanical
families:Cereals
Legumes
The first type contribute
carbohydrates while the
second are rich in protein
(nitrogen).

Although not all fodder crops are cereals we are
considering them in this section (cereal farming) because
they are usually grown together to provide a complete
range of nutrients.

Commercial field or arable farming is essentially the
growing of field cropsin arable land.

223
In geography, arable land (from Latin arare, to plough) is
an agricultural term, meaning “land that can be used for
growing crops”.
It is distinct from
‘cultivated land’
and includes all
land suitable for
agriculture, even if
it is not yetunder
cultivation.

224
There are various definitions of “field crops”. Cereals are often
included in this category but we have treated them as a
separate type of agriculture so we shall be
considering other crops under this heading.

225
Field crops are basically
vegetables that are
grown in large open
fields rather than the
smallish plots typical of
horticulture.
Tomato fields in the US

226
They include potatoes, tomatoes, onions, legumesand
brassicas.

227
This important vegetable
introduced from America can
come in all shapes and sizes.

228
These can also be of
many unusual colours,
apart from red. Such
varieties, known as
“heirloom” are typical of
horticulture rather than
field cropping.

229

230
Onions are also grown extensively for processing

231
As in the case of
commercial grain-growing,
mechanisation is an
essential element to
achieve profitability in field
crops.

232
Most operations such as sowing, planting and harvesting.
are carried out by
machines.

233
In many cases, farmers have contracts with agri-industries
which buy all the harvest as raw material for their
processing plants.

234
Industrial-scale tomato production in Italy

235
This arrangement is useful to farmers as they have an
assured market but it also puts them in a position of
weakness when negotiating prices and other conditions.

236
There can be environmental concerns in this type of
farming, because of widespread monoculture.

237
In spite of widespread use of machinery, ill-paid migrant
workers are today also essential to field crops in many
European countries and southern US.

238
Nowadays, developing countries are also starting to develop the commercial field
crop production sector. Theseare irrigated fields in Saudi Arabia

An industrial crop is grown to produce goods, not food.
e.g. to produce fibre for clothing.
Some examples include
flax, hemp, cotton,
tobacco, runbber. Fibre
crops are amongst the
most common industrial
crops.

242
There are three main groups of industrial crops, divided
according to their use:
Energy
Fibres
Other non-food

243
An industrial crop is grown to produce goods, not food. e.g.
to produce fibrefor clothing. There are three groups:
Energy-crops used to generate heat, electricity or
produce liquid fuels
Fibres-crops used to produce fibrous material for use in,
for example, car manufacture or insulation
Other-crops with an industrial use other than energy or
fibres.

244
This type of agriculture is being considered under this
section (i.e. agriculture in developed countries) but one has
to note that increasing amounts of such crops are grown in
plantations in developing countries.

245

246
Cropsused to generate heat, electricity or to produce liquid
fuels

247
Crops for heat andelectricity generation are choppedup,
and usually burnt directly in stoves and boilers, mixed with

coal for use in conventional power
stations or used in dedicated
biomass power stations.

248
Under this heading we have several products such as
biodiesel, and bioethanol(a petrol additive/substitute).
At present, biofuels
are usually used as
a blend with fossil
fuel (5% bio to 95%
fossil) for
conventional
engines.

249
Biofuels are a wide range of fuels thatare gaining increased
public and scientific attention, drivenby factors such as oil
price spikesand the need for increased energy security.

253
The 'fine linen' mentioned various times in the Bible has been
satisfactorily proved to have been spun from Flax. The
knowledge of spinning was known to the Canaanites and it
formed the clothing of the Saviourin the tomb when He was
buried. It was used for cord and sail-cloth by the ancient Greeks
as well as for lamp-wicks.

254
As a crop, flax is very demanding in terms of nutrients and
rapidly exhauststhe soil. It requires care and a rich soil to
secure a good crop.

255
Flax is harvested for fibre
production when still green. It is
pulled up with the roots (not cut),
so as to maximisethe fibre
length.
It is then soaked in
water to rot off the
non-fibrous material
in the stems.
.

256
Flax grown for seed is allowed to mature until the seed
capsules are yellow and just starting to split.
The seed is
pressed to produce
a valuable oil.

257
Flaxseed oil is cold pressed from the seeds, and
edible. The seeds are then hot pressed to produce
an industrial oil and solvent, known as linseed oil,
which is not edible.

258
Flaxseed oil has a very high level of omega-3 fatsacid so it
is most often used as a nutritional supplement rather than
for cooking.

259

260
Cotton is a fibregrowingaround the seeds of the cotton
plant, a shrub native to tropical and subtropical regions
around the world.There are about 50 species of cotton,
but only four are cultivated.

261
Virtually all of the
commercial cotton
grown today worldwide
is from varieties of the
American species.

262
The plant produces creamy-white flowers, which soon turn
deep pink and fall off, leaving the small green triangular
seed pods, known as cotton bolls, which contain the seeds.

AntoineVella 278
Horticulture is the subdivision of agriculture dealing with
the gardening of enclosed areas to grow vegetables, fruit
and ornamentals, in contrast to agronomy, which refers to
growing field crops(including industrial crops), and
forestry which concerns forest trees and products related
to them.

AntoineVella 279
Horticultureis sometimes known also as market gardening,
especially when it refers to growing vegetables. It can be
practised as a hobby or an economic activity.

AntoineVella 280
Within the context of this course, horticulture may involve
three types of produce:
•Vegetables
•Fruit trees
•Ornamental plants, especially flowers

AntoineVella 281
The relatively small-scale horticulturalproduction of fruits,
vegetables and flowers as cash cropsis also known as
market gardening.

AntoineVella 282
It is distinguishable from other types of farming by the diversity
of crops grown
on a small area
of land, typically,
from about
0.3-3 Ha, or
sometimes in
greenhouses.

AntoineVella 283
Traditionally marketgardening is based on providing large
urban areas with a
wide range and
steady supply of
fresh produce
through the local
growing season.

AntoineVella 284
Many different crops and varieties are grown, in
contrast with large, industrialized farms, which tend to
specialise in high volume production of single crops, a
practice known as monoculture.

AntoineVella 285
Compared to field crop farming, marketgardening also
employs more manual labour and gardening techniques,
compared to large-scale mechanisedfarming.

AntoineVella 286
We may also consider the different
aspects of horticulture according to
the medium in which the plants are
grown.
•Soil cultures
•Soilless cultures

AntoineVella 287
Soil culture may be further subdivided into:
•Protected culture with the use of greenhouses
•Semi-protected culture
using small plastic
tunnels
•Non-protected culture
in the open soil.

AntoineVella 288
This type of modern rounded greenhouse is nowadays
sometimes also known as “tunnel”.

AntoineVella 289
Another, less-used name
for low tunnels is “cloche”.

AntoineVella 290
Open soil allotment

AntoineVella 291
Soilless culture is also known as hydroponicssince the
plants are basically growing in water, with or without any
substrate.

AntoineVella 292
These may be further subdivided into:
Nutrient Film Technique in which plants are grown in a
water stream
Natural substrate culture using peat
Synthetic
substrate culture
using expanded
clay, polystyrene
(“jablo”), rockwool,
etc

AntoineVella 293

AntoineVella 294
This is a further
developmentof hydroponics.
The roots of the plants
are suspended in air
and a water with
nutrients is sprayed to
feed them.

AntoineVella 295
Young plantsgrowing in perlite, an artificial substrate.

AntoineVella 296
Perlite is an amorphous volcanic glass that has a relatively
high water content, typically formed by the hydration of
obsidian.
It occurs naturally and
has the unusual
property of greatly
expanding when
heated sufficiently.

The growing of fruit trees can be considered part of
horticulture system although it can also be found in certain
types of plantations (e.g. date and banana)

AntoineVella 300
There are many ways of classifying fruit trees, including :
•Type of fruit (succulent fruits or nuts)
•Biological cycle (deciduous or evergreen)
•Area of cultivation (temperate, sub-tropical, tropical)
•Use of the product (table or processing)
•Botanical family

AntoineVella 301
The Rosaceaeare trees, shrubs
and herbs comprising about 3,000
specieswhich can be very different

Maloideae

AntoineVella 303

AntoineVella 304

AntoineVella 305

AntoineVella 306
Traditionally considered as part of the Rosaceaefamily,
this group is now often treated as a separate family. There
is only one species of importance: the pomegranate Punica
granatum.

AntoineVella 307
The Rutaceaeare herbs, shrubs, and trees with glandular, commonly
strongly smelling leaves, flowers and fruit, comprising about 150
genera and 1,500 species. The flowers are often sweet-scented, nearly
always bisexual, and are actinomorphic or sometimes zygomorphic.
Generally, a nectary disc is situated between the stamens and the
ovary. The fruit is variable but in the cultivated species mostly a
specialisedberry known as hesperidium.

AntoineVella 308
The Oleaceaeare trees or shrubs comprising about 30
genera and 600 species. The fruit is variable but in the only
cultivated species, Oleaeuropea, it is a drupe.

AntoineVella 309
The Fabaceaeare mostly herbs but include also shrubs
and trees found in both temperate and tropical areas.
They comprise one of the
largest families of flowering
plants, numbering some
10,000 species. The fruit is
a legume. The only
cultivated fruit tree of
significance is the carob
Ceratoniasiliqua.

AntoineVella 310
The Moraceaeis a family of about
1,000 species–mostly trees -and
nearly all producing a
milky sap.

AntoineVella 315
Bedding and garden plants consist
mostly of young flowering plants
(annuals and perennials).

AntoineVella 317
The cultivation of house plants is a major sector
of horticulture in several developed countries
such as the Netherlands and Italy.

AntoineVella 318
Flowering pot plants are
those that are sold in pots
for indoor use.

AntoineVella 319

AntoineVella 320
These are produced specifically to be sold after they have
been cut from the mother plant.
Bloom uniformity and the
longevity are the two major
qualities sought by
commercial flower-growers.

AntoineVella 321
When the climate is suitable, this sector can be very
important, with a high added value component.

Dairy farming is a class of
agricultural enterprise for long-
term production of milk, usually
from dairy cows but also from
goats and sheep.

AntoineVella 329
Milk may be either
processed on-site or
transported to a dairy
factory for processing
and eventual retail sale.

AntoineVella 330
Historically,dairy farming
has been one aspect of
the work of small, mixed
farms.

AntoineVella 331
In the second half of the 20th century larger farms engaged
only in dairy production have emerged in developed countries.

AntoineVella 332
Large-scale dairy farming is only viable where either a large
amount of milk is required for production of more durable
dairy products such as cheese, or there is a substantial
market for fresh milk.

AntoineVella 333
As in other forms of modern commercial
farming in the developed world, dairy
farming depends on extensive use of
technology and machinery.

AntoineVella 337
In developed countries, milk is not consumed
“raw” but undergoes a certain amount of handling.

AntoineVella 338
Most countries have developed a
whole sector of industry
associated with dairy farming. The
main product of this industry is
undoubtedly cheese.

Cheese is a food made from the coagulated milk of cows,
goats, sheep and other mammals.

AntoineVella 340
It is basically the concentrated fat,obtained through curdling,
of the milk with varying amounts of liquid, according to the
type of product.

AntoineVella 341
The process of cheese-making is an imitation of naturally
occuring reactions in the digestive systems of newborn
mammals.

AntoineVella 342
Newborn mammals cannot chew solid food so they have to
ingest liquids. However a liquid would travel too fast through
the intestine and not allow all the nutrients to be extracted.

AntoineVella 343
What happens therefore is that, inside the stomach, the
liquid milk is curdled (by acids and bacteria) and becomes
solid so that it travels more slowly through the intestinal
tract, thus giving the organism time to digest and absorb all
the nutrients.This solidified milk is, basically, ‘cheese’.

AntoineVella 344
To produce cheese, milk is
warmed to 35-38 C (the stomach
temperature of the calf) then
curdled through the addition of
acids or the action of bacteria.

AntoineVella 345
Thus the fats and proteins in the milk
coagulate and form what is known as ‘curd’
which is actually a form of ‘cheese’.

AntoineVella 346
The curd will then be processed in many different ways
according to the type of cheese being manufactured.

AntoineVella 350
Ranching is the practice of raising large numbers of grazing
livestock (cattle or sheep)for meat or wool(not milk).

AntoineVella 351
Ranching most often applies to
livestock-raising operations
carried out over extensive
areas in America, though there
are ranches in other regions.

AntoineVella 352
Traditionally horses are used to herd cattleor sheep,though
nowadays,motorised transport is becoming more common.

AntoineVella 353
Ranching and the “cowboy” tradition originated in the
Mediterranean, especially in Spain,out of the necessity to
handle large herds of grazing animals.

AntoineVella 354
Because grazing land was poor, large areas were
needed for the herds and, before the Industrial Age,the
livestock could be controlled only on horseback.

AntoineVella 355
During the Reconquista, Christian nobles received large
land grants that the Kingdom of Castile had conquered
from the Moors. These landowners were to defend the
lands put into their control and could use them for earning
revenue.

AntoineVella 356
In the process it was found that open-range breeding of
sheep and cattle was the most stuiable use for vast tracts.
Particularly in the part of Spain now known as Castilla-la
Mancha, Extremadura and Andalusia
Countryside in Extremadura. SW Spain

AntoineVella 357
Even today, large areas of Spain are dedicated to extensive
ranching, especially of sheep

AntoineVella 358
In other parts of the Mediterranean, a similar type of animal
husbandry also developed especially in Maremma
(Tuscany) and the mouth
of the Rhone.

AntoineVella 359
The Camargue is nowadays a
wetland nature reserve,
renowned for its breeds of open-
range horses and cattle.

AntoineVella 360
This type of farming is also found in the
S.Tuscany region of Maremma.

AntoineVella 361
The first Spanish settlers in America brought their cattle
and cattle-raising techniques.
Huge land grants by
Spanish (and later
Mexican) governments
allowed large numbers
of cattle to roam freely
over vast areas.

AntoineVella 362
The prairies of North America proved to be perfect as
grazing land for cattle and, together with cereal-growing,
this became the primary agricultural activity of the region

AntoineVella 363
Ranching and cereal-growing
gradually took over entire regions
of N. America, pushing out the
indigenous fauna.

AntoineVella 364
Although we’re considering ranching as an agricultural
activity of developed countries, it has also been introduced
in some other regions (notably Brazil and Argentina) to
satisfy the demand for beef in the developed world

AntoineVella 365
In the colonial period, from the pampas regions of South
America all the way to the Minas Geraisstate in Brazil, were
often well-suited to ranching, and
a tradition developed that largely
paralleled that of N. America.

AntoineVella 366

AntoineVella 367
The gaucho cultures of Argentina, Brazil and Uruguay are
among the ranching traditions born during the colonial period

AntoineVella 368
In the 20th century, ranching expanded into less-suitable
areas of the Pantanal(MatoGrosso–a wetland) in Brazil.
This caused extensivedeforestation, as the rainforest
was cleared to allow grass to
grow for livestock.

AntoineVella 369
Many of indigenous peoples of the rain forest opposed this
form of cattle ranching and protested the forest being burnt
down to set up grazing operations and farms. This conflict
is still a concern in the region today.

AntoineVella 370
In Australia, the ranches are known as 'stations' raising
either cattle or sheep. The largest cattle stations in the
world are located in Australia's dry rangeland in the
outback averaging 10 thousand km2.

AntoineVella 371
Anna Creek Station, in South
Australia, is the world's largest
cattle station. Its area is roughly
24,000 km². (6,000,000 acres) of
semi-desert which can support only
small numbers of animals.

AntoineVella 374
Intensive livestock
farming involves
the breeding
and/or rearing of
large numbers of
animals, often in
confined spaces.

AntoineVella 375
In this presentation we shall be considering poultry and pigs
although other species, such as rabbits, may also be farmed
this way.

AntoineVella 376
Poultry farming is the practice of raising domestic birds such
as chickens, turkeys, ducks, and geese for the purpose of
farming meat or
eggsfor food.

AntoineVella 377
More than 50 billion chickens are raised throughout the
world every year as a source of food, for both their meat and
their eggs.

AntoineVella 378
Chickens raised for meat are called broilers, whilst those
raised for eggs are called laying hens or layers. Some hens
can produce over 300 eggs a year.

AntoineVella 379
Broilers are generally held in large groups either in
environmentally controlled housing or inopen, naturally
ventilated poultry houses.

AntoineVella 380
Theyare usually kept free on deep litter withautomated
provision of feed and water. In most countries, commercial
breeds selected forrapid growth, are used.

AntoineVella 381
In 2010 a newEU directive
imposed a maximum bird
density which must not
exceed 33-39 kgs per m
2
.
Density is calculated by kg per
m
2
because the smaller the birds
the less space they need.

AntoineVella 382
In egg production, the majority of commercial layers are kept
in battery cages.
There iswide variation in space allowance per bird from 300
to 400 cm
2
in places such as Brazilor India tothe current
550 cm
2
per hen in the EU.

AntoineVella 383
After 2012, hens in the EU will be kept in cages with a
minimum space allowance of 750 cm
2
per hen (from 550cm
2
).

AntoineVella 384
Chickens will naturally live for 6 or more years but after one
year, their productivity will start to
decline and most commercial
laying hens are slaughtered
at that age.

AntoineVella 385
Poultry which is kept in the open –usual having a light
density per m
2
–is said to be free range but this is more
typical of mixed farming.

AntoineVella 386
Intensive pig-farming consists in keeping large numbers of
pigs in indoor pens while pregnant sows are housed in
“cages” known as farrowing crates.

AntoineVella 387
The use of farrowing crates
has resulted in lower
mortality among newborn
piglets and decreased costs.

AntoineVella 388
In general,however,the over-intensification of pig-farming
gives rise to concern about animal welfare especially as
regards overcrowding and lack of space which causes
physical and mental
stress to the animals.

AntoineVella 389
Most large-scale pig farms house 5,000 or more animals in
buildings. With 100 million pigs slaughtered commercially
each year, these efficiencies deliver affordable meat for
consumers and larger profits for producers.

This is asystem of farming where different types of
agricultural practicesare conducted together, on a single
farm.

AntoineVella 393
On such a farm we will therefore find both the growing of
crops and the raising of livestock.

stemmed fruit trees

AntoineVella 394
Because of the lack of specialisation, mechanisation is
more difficult and such farms are usually small.

AntoineVella 395
Although, for convenience’s sake we’re considering mixed
farming as a system of developed countries, it can of course
be found even in developing regions.

Nowadays many mixed farms in countries like Italy, Spain
and France supplement their income by organising tourism-
related activities.

AntoineVella 400
Although the name of this type of climate derives from the
basin of the Mediterranean Sea it is, in fact found in several
other places round the world.

AntoineVella 401

AntoineVella 402
The most prominent features of this climate are the long hot
dry summers and the mild wet winters, with temperatures
that rarely reach 0 C.

AntoineVella 403
Another relevant character is the chronic lack of water which
has a significant impact on agriculture.

AntoineVella 404
This is distinctive and has been developing since ancient
times. It is traditionally a subsistence type and although it
has become more commercialisedin areas such as
California, Australia and
some parts of Italy,
smallholdings are still
the norm in most
countries of the
Mediterranean basin
itself.

AntoineVella 405
Another feature of the Mediterranean basin is the scarcity of
large plains suitable for cattle.

AntoineVella 406
As a result, agriculture is based mostly on
crop farming complemented by small
ruminants.

AntoineVella 407
As regards crops the characteristics include:
•A crop rotation of 4-5 years
•Extensive drought-resistenttree crops.

AntoineVella 408
A typical Mediterranean crop
rotation is based on cereals
(wheat and barley) and legumes
(beans and/or fodder).

AntoineVella 409
The most economically important tree crops are the olive,
grapevine, citrus, stone fruits and -in the southern coast of
the Med. Sea –date palms.

AntoineVella 410
Olives are the symbol of Mediterranean agriculture. The
Mediterranean itself is defined as the region where the olive
tree grows.

AntoineVella 411
Although the grapevine originated
outside the Mediterranean area, its
cultivation –and the consequent
wine culture -has also become
synonymous with the region

AntoineVella 412
Because of the high population density and the numerous
settlements all around the Mediterranean basin, market
gardening is also
important, where
water is available.

AntoineVella 413
The Mediterranean and its agriculture will be the topic of
another presentation where it will be discussed in more
detail.
