COMPACT RURAL SETTLEMENT.
In such settlements,
houses are built close to
each other. They
generally develop close
to a railway station, a
road, a well, a quarry or an industrial site.

SCATTERED RURAL SETTLEMENT
In such settlements,
houses or the individual
farmhouses are isolated
or scattered and are
located away from each
other. They develop
mostly in the plateau, forested or hilly areas.

AGRICULTURA DE ROZAS (SLASH AND BURN)
Slash-and-burn is an
agricultural technique that
involves the cutting and
burning of plants
in forests or woodlands to
create fields. It is subsistence
agriculture that typically uses
little technology.
Today the term slash-and-
burn is mainly associated
with tropical rain forests.
Slash-and-burn is used by
between 200 and 500 million
people worldwide. In 2004 it
was estimated that,
in Brazil alone, 500,000 small
farmers cleared an average of
one hectare of forest per year
each.4
RICE AGRICULTURE.
Rice cultivation is well-suited
to countries and regions with
low labor costs and high
rainfall, as it is labor-intensive
to cultivate and requires ample
water. However, rice can be
grown practically anywhere,
even on a steep hill or
mountain area with the use of
water-controlling terrace
systems.
The traditional method for
cultivating rice is flooding the
fields while, or after, setting
the young seedlings.

MECHANIZED AGRICULTURE.
Features:
1. High investment.
2. Advanced techniques.
3. High productivity.
4. Planters, harvesters,
tractos, trucks, irrigation
techniques, fertilisers,
pesticides, genetic
engineering (seeds).

GREENHOUSES
A greenhouse (also calleda glasshouse or a hothouse) is abuilding or complex inwhich plants are grown.Commercial glass greenhousesare often high tech productionfacilities for vegetables orflowers. The glass greenhousesare filled with equipment likescreening installations, heating,cooling, lighting and also maybe automatically controlled by acomputer to maximize potentialgrowth.
A greenhouse is a structuralbuilding with different types ofcovering materials, such asa glass or plastic

EXTENSIVE LIVESTOCK FARMING.
The livestock grazes on large
pastures in the open air. The
productivity and capital
invested is lower than
intensive livestock farming.

INTENSIVE LIVESTOCK FARMING.
Intensive animal farming refers to the keeping of livestock at higher stocking densities . The main products of this industry are meat, milk and eggs for human consumption. Confinement at high stocking density is one part of a systematic effort to produce the highest output at the lowest cost. Confinement at high stocking density requires the use of antibiotics and pesticides to mitigate the spread of disease and pestilence exacerbated by these crowded living conditions

CASH CROPS (CULTIVOS COMERCIALES).Large estates/plantations with
monocultures of cocoa, tea,
coffee, bananas, pineapples, etc.
These farms are owned by great
multinational companies. These
cash crops are mainly cultivated
in Central and South America,
Africa and Asia.

DEFORESTATIONDeforestation occurs for
many reasons: one is to
clear land to be used
as pasture for livestock and
plantations.
Large parts of the
Amazonian rainforest have
been deforestated to be
used as pastures for the
cattle and to plant soybean.

FISHERYFishery is the industry of
catching, processing and
selling fish. A fishery may
involve the capture of wild
fish or raising fish
through fish
farming or aquaculture.
There are two types of
fishing: 1. coastal fishing
(near the coast, small boats, it
takes one or several days) and
2. off-shore fishing and deep-
sea fishing (it takes several
weeks or months, large boats,
freezer factory ships).

Large scale commercial
fishing boats are owned
by multinational
companies. Commercial
fishermen harvest a wide
variety of animals,
ranging
from tuna, cod, carp,
and salmon to shrimp, kr
ill, lobster,
clam, squid, and crab.
