Sustainability seeks to provide the best
outcomes for the human and natural
environments both now and into the indefinite
future.
It is a relating to the continuity of economic,
social, institutional and environmental aspects of
human society, as well as the non-human
environment.
It is intended to be a means of configuring
civilization and human activity so that society, its
members and its economies are able to meet
their needs and express their greatest potential
in the present, while preserving biodiversity and
natural ecosystems, and planning and acting for
the ability to maintain these ideals in a very long
term.

The locational advantages

Site A – Market
Gardening

Relief : flatland
Light intensity : high,
i.e. there is sufficient
sunlight for the
process of
photosynthesis,
especially for
sunflowers which favor
sunlight.


Temperature : moderate temperature

Soil :
~loamy and slightly acidic soil is suitable
for planting flowers
~Soil moisture content is high enough for
the flowers’ growth
Site B – Chicken Farm



In site B, it is a slope.
However, terracing is
difficult to practice
because there are
over 13 trees. The soil
is clay loam and the
pH value is 7.5. Many
fertilizers need to add
so as to suit the plant.
In order to save the
production cost, we
suggest that a chicken
farm should be build.




We are not going to keep
the chickens in cages.
Instead, we are going to
set an area for them to run.
It provides a large area for
the chicken to run.
Therefore , the quality of
the chicken will be higher.
There can be a larger
market and increase the
profit.
Site C - Plantation

Site C is not a
flatland.

If we want to
develop this site,
we need to practice
terracing.
Planting of fruit trees is the most suitable
because of the following reasons:

- The soil water content is low. (about
10.02%)

- The pH value is 6.5 (slightly acidic).

- The soil type is loam, which is the
most suitable soil for plant to grow.
 Therefore, we can avoid to use fertilizer
and achieve environmental- friendly.
 Also, the root of the trees can hold the
soil and prevent soil erosion.





We choose the following fruit to plant:
-banana
-longan
The main reason for us to choose these trees is
because we can see many of these fruit trees
within the site. We believe that both the soil
acidity and micro-climate is suitable
Site D – Greenhouse

Large piece of flatland




The soil- water content is the lowest among
the four (only 60.8%) and it is difficult for
plant to grow.
The pH value is 7 (neutral) and soil is clay
loam. It is a little bit not the best site for
various types of farming
The average temperature is high (about
36.1°C).
So, greenhouse, which can control the
temperature and soil type, is the most
suitable farming activities there.

Appropriate eco-farming techniques

Growing crops in a
greenhouse

Use renewable
energy (eg.solar
energy, wind
power.)

Practice organic
farming

Grow chillies &
spring onions

Use a scarecrow to
keep away birds

Practise soil
conservation by
fallowing, crop
rotation
Locational advantages for SOLAR ENERGY
Site A
Adequate sunlight
(1480 lux – 1700
lux)
 Smaller number of
trees means that
more sunlight can
reach the ground


Larger scale of solar energy
panels can be built

The land is quite flat, with the
highest accessibility (closest to
the town centre in Cheung
Chau)
Site D
Adequate sunlight (700 lux)
 Solar energy panels can be built on the
top of the greenhouse, providing the
energy needed for the operation of the
greenhouse.
 Most of the vegetation there is lowgrowing, mainly shrubs, so it is unlikely
for them to block the sunlight



The electricity generated
can supply the farms in
Site B, C and D. Power
lines can be built along
the ‘Mini Great Wall’ to
save the cost
A road has been built
reaching Caritas Chan
Chun Ha Field Studies
Centre, so cars can
transport the needed
materials to build the
solar panels
Locational advantages for WIND ENERGY
Site A

The wind speed there
can reach 4m/s, so
the wind turbines can
be driven

It is more
economical to build
ONE only because
there are solar
panels in Site A, the
total amount of
energy is sufficient
for the sprinkler
system
 It
has high
accessibility. It is
located at the
intersection of
different roads
Site B



It is near the shore,
the sea breeze can
drive the wind
turbines.
Wind speed is 4.1 m/s
A flat land is available

Two larger wind
turbines are to be
built, because they
have to supply the
necessary electricity
for Site B, C and D

A road has been built
reaching Caritas Chan
Chun Ha Field Studies
Centre, so cars can
transport the needed
materials to built the
big wind turbines
