This is a paper to encourage the adoption of the Controlled Environment Agriculture (CEA) system, in Nigeria to help boost food production by maximizing available space.

1. THE ADOPTION OF THE CONTROLLED
ENVIRONMENT AGRICULTURE
SYSTEM IN NIGERIA
Abdulmuizz O. LAWAL (UI)
Azeezat BUSARI (LAUTECH)

2. The CEA system
The Controlled Environment
Agriculture system is an
avenue to nurture plants in a
confined space where
environmental factors can
be manipulated to quantities
that best suit the crops

3. Why CEA?
 To solve the problem of space
 To make food available all year round
 To optimize resources and maximize yield

4. The CEA System in Nigeria
Most of the CEA systems in Nigeria are limited to;
 Educational Institution
 Research Institute
*IITA 2016

5. Potential of a CEA System
2014, two German Scientists, Banerjee and
Adenaeuer increased the potential of a 0.25ha
land to 68ha using a Controlled Environment
Agriculture System

6. Elements that are important to plant growth
SOIL
LIGHT (SOLAR ENERGY)
WATER
CO2
NUTRIENTS (MICRO AND MACRO)

7. SOIL
 It provides support
 It houses other important elements
Alternative
Inorganic Organic
 Saw dust
 Porous Clay mould
 Pertile
 Plastic
 Foam
*PERTILE

8. LIGHT (SOLAR ENERGY)
 It helps activates Photosynthesis in plant leaves and other green parts
 It causes Phototropism in plant
Alternative
 Red light stimulates flowering in plants
 Blue light is important for Phototropism
Artificial light (LED)

9. WATER
There is no alternative to water but the quantity used can be optimized
Solution
 Application of water through drip irrigation
 Collection and Re-use of water

10. CO2
 There is a higher demand for CO2 in a CEA system but
the closed system restricts the rate at which it is
replenished
Alternatively, CO2 can be replenished by;
Natural or forced ventilation
Combustion of hydrocarbon
Decomposition of bio-mass

11. NUTRIENTS
Alternative
Inorganic Organic
 Animal waste (duck droppings)
 Aquaponics
 Cultured solutions
 Commercial soluble fertilizer

12. Downsides of a CEA system
The initial cost of setting up an intensive or
a closed CEA system is very high.
There might be a problem of acceptance
by our local farmers

13. Upsides of a CEA system
Yield of crops are increased
Food is available all year round

14. CONCLUSION
The CEA System is a very important
method we need to adopt to maximize
space, to meet the growing food
demand and to make food available all
year round.
