Cultivate an interest in the agricultural sector with a three-level secondary
course designed specifically for the Caribbean.
• Explore regional and global practices and developments in agriculture.
• Enhance understanding of the relevance of agriculture with a project-based
approach to select topics.
• Prepare for study at the CSEC® level with a dedicated project-based chapter
scalable to other topics and SBA research at the CSEC® level.
• Consolidate learning with clear chapter objectives and end-of-chapter
evaluation.

Agriculture can affect a nation’s health by providing healthy
foods and medicines, and by contributing to a healthy
environment for the people.
A balanced diet, using foods of nutritional value from each of the
main food groups, is recommended for a strong and healthy
population. The present trend of eating processed foods with a
high sugar and salt content means that more people
suffer with diabetes and hypertension.
Agriculture provides us with plants that have
Agr
icu
medicinal uses. For example, in Grenada a
ltu
re
spray produced from nutmeg oil is used for
medicinal purposes. Aloe vera and
turmeric are used in creams and
ointments to help patients suffering
from skin conditions and burns. Can
you think of other plants in your
country that have medicinal uses?

Food is one of the main requirements for life. The agricultural
industry must therefore produce a sufficient quantity and quality
of food. The ability to produce food is referred to as food
security and it is necessary to allow human development.
Food security resulting from a strong agricultural industry is
considered to be one of the primary requirements of a stable
nation. When a large percentage of the population has no
food security these people are unable to develop
and so nor can their country develop. No nation
d
can effectively grow while its people are
oo
df
hungry and starving.

Have you been listening to the world
news lately? Can you tell which
countries of the world have a problem
with food security? Are there any
countries with food security problems
in the Caribbean?
Useful breakdown and application of the
design process to support the STEM approach
while guiding preparation for study at the
CSEC® level and for CVQ certification.

any limits to the solution).

Goods are manufactured articles made

from raw materials that have been

produced by agriculture. Raw materials
ood
include cotton, coconut, cocoa, coffee beans,
s
sugar cane, fruits, timber, tobacco, nutmeg and
animals such as poultry, cattle, pigs and fish.
Fibres for clothing come from cotton, flax and hemp. Leather for
shoes, bags and jackets is obtained from the skins of cattle,
goat and sheep.
Timber and thatch for houses are obtained from a range of
trees. Lumber, for products such as furniture and paper, is also
obtained from trees.

Agriculture employs a large number of people in a wide range of
jobs. The income from their employment enables people to
satisfy their basic needs, and enjoy recreation and leisure
activities. Recreational activities associated with agriculture
include fishing, birdwatching, hiking and camping.
Farmer Josephine notices that her tomato plants are not growing as they should. They are too short and
they do not produce many tomatoes. Farmyard manure is very useful for improving soil fertility. It adds plant
nutrients and improves both the soil structure and the soil's ability to hold water. However, manure is bulky
and heavy to carry and it has to be rotted before use, because it can ‘burn’ the plant if it is applied fresh.
Manure can also contain a lot of weed seeds, which then germinate and grow between the crops. Chemical
fertilisers are too expensive. What can Farmer Josephine do to get better yields and save money?
Copy and complete the design brief that Farmer Josephine could have written as she worked through
her problem.
On a small subsistence farm the
farmer will be engaged in all the
occupations. The farmer will be the
labourer, the skilled worker, the
supervisor and the manager.
On the other hand, a large
plantation, estate or commercial
farm employs a large number of
people. In this case the farmer will
most likely be the manager.

Mangoes are usually available
in large quantities at specific
periods, when they are
in season. However, large
portions go to waste. Many
people in the Caribbean have
mango trees and would love
to have some version of the
fruit throughout the year.
We think there is a need to
preserve the excess fruits
using an easy, economical and
convenient method.
Plant growth depends on the physical and chemical properties of the soil. Artificial fertilisers _________
