I Introduction
Why Farming?
Singapore is one of today’s most developed countries (United, 2009). Food security is
essential to ensure that Singapore has the vital edge in development (Maxwell, 1996),
therefore the government endeavours to ensure food security by importing food from other
countries, and other efforts such as the Jilin project (Ngiam, 2010). However, food security is
essential for self-sufficiency especially in emergency situations where food may be scarce.
Currently, self-sufficiency may seem ambitious considering that the land available for
agriculture is limited to about 1% of Singapore’s total land area (Alpha, 2010). Furthermore,
from 1970 to 2000, local food production plummeted from 85% to 7% (Ngiam, 2010),
increasing dependency on imports, whilst lowering self-sufficiency. Thus, to ensure self-
sufficiency, our project proposes to tackle the problem of land-shortage and achieve food
security, which will be presented systematically throughout the report.
Cropping it UP! - Written Report! 4
Goals
Our project aims to tackle the aforesaid problem, introducing modern alternative farming
techniques in Singapore (mainly hydroponics and aeroponics) (Manda, 2010). After evaluating
Sea-Farming and Vertical Farming, we discovered that Vertical Farming is more likely to
succeed. This is further elaborated upon below in “Alternatives to Farming
Techniques” (Section III).# Vertical Farming increases local food production without
compromising land intensive activities illustrated in “The Genius of Vertical Farming” (Section
IV). Our achievement of attaining water security in the early millennium has made us
optimistic that food security is within Singapore’s reach. Currently, the methods implemented
by Singapore include desalination, NEWater, water catchment areas, and importation of
water from Malaysia (PUB, 2009). By analysing the approach and methods successfully
implemented by Singapore, we are able to adopt and apply them in Vertical Farming, thus
enhancing the success of our project.

If we fasten our attention on what we have, rather than on what we lack, a very little wealth is su!cient.

I I Case Study : Attaining Water Security
The Problem
Singapore has been dependent on Malaysia for its water supply even before the British
pullout in 1965. Singapore imports more than 40% of its water needs from Malaysia (Lee,
2003). When Singapore's water contract with Malaysia expires in 2061 (Hoe, 2010), we will
be under immense pressure as the population’s survival is threatened. To ensure that
Singapore is well prepared for the cessation of Malaysia’s water supply, the government has
to source out different solutions before then. Dr. Lee Poh Onn, an economist and Fellow of
the ASEAN Economic Review, and author of numerous monographs including “The Water
Issue Between Singapore and Malaysia: No Solution in Sight?” points out that the reasons for
Singapore’s dependency have been reiterated below in point form. Singapore’s approaches
to the problem would be addressed under “Singapore’s Approach.”
Causes of the Problem
Lack of water sources
Dr. Lee’s report highlighted Singapore’s lack of water sources was a significant problem, as
the water catchment sites located across Singapore were the main sources of water. Our
study revealed that in 1965, Singapore had to depend on only 3 main reservoirs, mainly the
MacRitchie, Pierce and Seletar reservoirs.
Cropping it UP! - Written Report! 6
Cost of Treatment
Dr. Lee showed that Singapore had to invest heavily
in water treatment plants to achieve self-sufficiency.
Our study also revealed that because non-potable
water was polluted with industrial pollutants and
indiscriminate littering/dumping of refuse, rendering
the cost of treatment extremely high. (Figure 2.1) shows
the then polluted Singapore River.
Consumption/Wastage
Our study also showed that given the lack of water sources
in Singapore, wastage and inefficient use of water by the
public further compounded the problem, prompting the
government to introduce extensive media campaigns to
save and ration water. (Figure 2.2)

Brainstorming
Singapore’s Alternative Approaches
Procedure of Singapore’s attempt to solve the problems stipulated in the previous section.
Lack of Water Sources
• Build more water catchment areas
• Improving collection of surface-runoff in existing catchment areas
• Rivers are dammed and turned into instant reservoirs e.g. (Punggol River, etc)
• The cheapest method of creating reservoirs was to dam them up as seen in (Figure 2.4)

Figure 2.4 Serangoon and Punggol Rivers being damed as reported by
The Straits Times (The Straits Times, 2008)
Cost of Treatment
• Economic pursuits in other industries were used to generate sufficient profit for
development of technology to source out various water sources.
• As treatment costs for potable water depends on the level of pollutants found in the water,
the goal was to minimise pollutants reaching the water courses. The formation of Anti-
Littering Campaigns, fines and other enforcement actions against littering, and cleaning up
of all water courses including rivers helped meet that goal.
Consumption and Wastage
• The government introduced water tariff reform to encourage Singaporeans to use water
sustainably1. This reduces the demand for water as consumers will have to pay a tariff for
consuming more than the national average.
• Public education campaigns through media reiterated the message to conserve water2;
Moral Suasion has always been an option for governments, but is not vey effective as it is
voluntary and thus only the minority would take heed of such campaigns.
• Infrastructures were built for industries to use industrial grade water for industrial use, such
as toilet flushing systems, and air conditioning cooling towers. Non-potable water for use in
industries is very effective in reducing treatment cost for both provider and consumer.

1 Imposition of water tariff, Water Conservation Tax (WCT), Water Borne Fee (WBF) and Sanitary Appliance Fee (SAF) (Torta-
jada, 2006).
2 e.g. using running water to wash cars was discouraged(PUB, 2008), in the early days water rationing was introduced and
the cost per cubic meter was increased.
Recycling Water
NEWater - Singapore’s approach to recycling water.
• Modern technologies such as reverse osmosis have been deployed to recycle drinking
water from waste water. Today NEWater comprises 30% of our water consumption by
2010 (PUB, 2008).
Roger’s Numerical Analysis
Roger, a then member of the Singapore Water Agency tackling the problem, in his analysis of
Singapore’s different approaches to solving their water problem, considered the significant
and insignificant factors, and weighted the data on a numerical basis, to offer the best
solution. His findings revealed that all the approaches that were considered were equally
significant and therefore recommended an adoption of all solutions.
As shown in (Table 2.5), the numerical figures indicate that all four methods were equally
feasible. All 4 methods were implemented to solve Singapore’s problem. However, Roger’s
method of analysis is not very reliable as would be discussed in the next section - “Our Aims
and Propositions”

Conclusion to our Case-Study
From the above, together with technological advancements
and adoptions, Singapore has adopted all four(4) strategies to
diversify its water sources as a solution to water security.
(Figure 2.6) shows a graphical representation of the points) :-
1. Imported water from Johor (25%);
2. Desalinated water from the sea (15%);
3. Water from local catchment (30%);
4. NEWater (recycled water from local waste water) (30%).

I I I Alternatives to Farming Techniques
Agricultural status in Singapore
As with the case of water, we now also import much of our food; an astounding 95%
(O’Brien, 2009). Since its founding, our vast lands were put to private agricultural use by in-
dividuals. With the advent of industrialisation and commercialisation of Singapore's economy,
we witnessed this agricultural use dwindling. Although we managed to house the population
in proper homes and built a viable economy, we have become dependent on imported food,
because we had to give up agricultural space for development. Thus, the development of
land has dwarfed agricultural production. Growing our own crops seems to be the best solu-
tion to alleviate this problem.
Brain-Storming
Cropping it UP! - Written Report! 12Figure 3.1 Brainstorming performed by our group to match that was done as explained in the case study
Our Aims and Propositions
Solutions to our land scarcity are:- (1) large scale farming in Singapore either on the sea (Sea-
Farms), i.e. building closed cylindrical floating platforms harnessing sea space to our advan-
tage, or (2) the use of high-rise towers for farming to increase the crop to land ratio (Vertical
Farming). The use of both these methods can satisfy our objective of attaining self-sufficiency
3.
The lack of land space is negated when we consider farming on sea. However, given the
state of the technology and research at this present time, farming on sea appears to be a vi-
able, but distant, possibility. Sea-farms are exposed to the elements such as storms, making
them vulnerable to frequent damage. These, among other factors, may erode Government
support for sea-farming. On the other hand, the sky is the limit for vertical farms. Both these
alternatives solve the crucial problem of lack of land space.

3 As mentioned previously in “I Introduction”
Adopting a similar approach to Roger’s system of weightage, we have also considered,
weighed, and tabulated, on a numerical basis, the feasibility of both Vertical Faming and Sea-
Farming (Table 3.2). Roger has clarified through emails that his figures were arbitrarily
selected, and therefore unsubstantiated. Avoiding Roger’s error of using arbitrary figures, we
conducted a survey(A:8) to ascertain the feasibility of Vertical Farming as opposed to Sea-
Farming. An indroduction inclusive with video links and websites to educate the surveyees
before they decide on their rating. the modal value for the survey was used in the table.
A practical approach would be to adopt Vertical Farming as it uses vertical space as opposed
to horizontal, limited, space. It produces approximately 20 times the normal production vol-
ume for field crops, and requires 5% less of the normal water requirements (Walsh, 2008).
The figures revealed by Valcent clearly suggest that Vertical Farming gives high yields with
minimal use of land (Walsh, 2008).

Decision
In the circumstances, we have therefore decided that farming “vertically” is the best alterna-
tive. Although Singapore executed 4 “taps” in their quest for water security, a 2-pronged ap-
proach of implementing both Vertical Farming and Sea Farming is not supported by our sur-
vey (Table 3.2). Hence, we decided to abandon the idea of Sea-Farming for the time being,
and focus on the more viable plan to build a prototype Vertical Farm; and highlight the impor-
tance of self-sufficiency, and kindle entrepreneurship in the business community.
Objectives for Vertical Farming

Traditional Farming
Vertical Farming
Thus, this new idea, together with today’s modern farming techniques (hydroponics, aero-
ponics), which can increase plant growth density even further, is the key to improving land to
crop ratio. As observed in (Figure4.1), the same quantity of crops could be harvested in the
same time using a smaller base area in a Vertical Farm than a conventional farm.
With all these pros, a probable reason why the government hasn’t considered Vertical Farm-
ing is because the people are unaware of it (Figure 4.2). Thus, to educate the public, a work-
shop would be organised, as would be introduced later.
In the next section, we introduce a design of a Vertical Farm prototype, 10 storeys tall, incor-
porating various features such as research facilities, restaurants, market, hands-on opportuni-
ties for the public, and the use of modern technology.

VI Marketing Strategies
Tours
A reliable blog post revealed that younger Singaporeans are technology savvy (Techzav,
2008) and are amenable to alternative farming techniques. Tour guides trained in all aspects
of vertical farming would conduct organised guided tours(Table 6.1), and field various ques-
tions from visitors to encourage participation in tours and better understand the mechanics
and concepts behind vertical farming; thereby inculcating the importance of self sufficiency,
and support for our prototype.

Shuttle Bus
Learning from Singapore Science Parks (SSP, 2010), free shuttle busses may ferry visitors to,
and from the farm, minimising travel time and maintaining customer satisfaction. Bus
frequency is increased on peak days to cater for additional visitors (Table 6.2).

Location
From Singapore Land Authority’s available community use sites (A:4) (SLA, 2010), we
decided to erect the Vertical Farm in the Jurong area, as the area will be commercially
remodelled (Rashiwala, 2008), and land is much cheaper, making project cost more feasible.
The Jurong East bus interchange and MRT Station makes it conveniently accessible to
visitors.

“ Cropping it Yourself ”
Being an interactive venue, this is a program to entice people to visit and to make return visits
to the farm. It allows actual hands-on planting sessions for the general public to grow their
own crops on two of our dedicated levels, allowing them to return regularly to check on the
status of their crop and take it home when it reaches maturity. A nominal fee of S$10 is levied
for the program. Subsequent admissions for visitors undergoing the programs would be free.
The program includes a Workshop, introducing high tech farming methods, and theory and
techniques of seed planting for proper growth. This workshop would also educate the public
on the importance of vegetable consumption, as our survey (A:1) reveals an ignorance in the
aspect of nutrition and balanced diet(A:1).

Admission
Prices are determined by adopting the prices of various learning centres (Singapore Science
Centre) which charges admission to students, adults and senior citizens at $5, $9 and $6
respectively(SSC, 2009). Prices are subsidised for financially dependent people so they are
able to afford entry.
Academic Institutions4 and Organised group packages (inclusive of a free meal)
Priced at S$6 S$6 S$7 for Students, Adults and Senior Citizens respectively.
The Organised Group Package is ideal as a tool to entice schools organising excursions to
the vertical farm as prices appeal more towards schools. Educating the youth at a very young
age leaves a lasting impression on the minds of the future generations, so that Vertical
Farming may be the way of life for time immemorial.

VII Finance5
Financial success is the backbone of most communal ventures, and is a crucial consideration
before implementation. Success or failure is determined by whether the venture can sustain
itself financially. A detailed financial analysis of the project is therefore set out below.

labour cost is S$3,435,000 [S$1,865,000 (Table 7.3) + S$1,570,000 (Table 7.2)]. The annual
estimated gross revenue is S$23,263,375 (Table 7.4). From the figures, we can achieve an
annual net profit of S$19,828,375 (Figure 7.5) [S$23,263,375 - S$3,435,000]. At this rate, we
will break even in 6 years. ($117,609,000/$19,828,375 = 6 years). This proves its success.

VII I Potential Sponsors/Partners for our Project
SPRING Singapore (Standards, Productivity and Innovation for Growth)
Help for new and emerging enterprises in Singapore is readily available from SPRING
Singapore, a statutory board, responsible for helping Singapore enterprises grow. They help
enterprises by financing development, technology and innovation. As they are willing to
finance technology and innovation, we are inclined to believe that the SPRING foundation
would be interested in funding our project.
Environment & Water Industry (Development Council)
The Environment & Water Industry (EWI) provides overall direction and coordination of efforts
in developing and growing the water and environment industry in Singapore. EWI provides
two critical ingredients - a financial incentive, as well as mentoring and guidance by special-
ists. We are confident that the Vertical Farm project, being a national, pubic project, is worthy
of sponsorship by EWI.

IX Solutions to Anticipatory Problems in the Vertical Farm Prototype
Competition from Local Producers
The success of the entire scheme will be greatly dependant on the marketability of the
produce from the Vertical Farm. Competition from local producers and/or imported produce
will be a factor affecting the financial viability of the project.
Effective ways to overcome such competition in Vertical Farming are to have economies of
scale, elimination of rejected crops, and the palatability of the produce. These factors may
help to bring cheaper and better tasting produce to the public.
Variability of amount of sunlight available
The project employs “Hybrid Solar Lighting” to infuse sunlight into the building. Roof mounted
‘solar collectors’ filter infrared light, transmitting visible light through bundles of optical fibres
to the crops. The Hybrid Solar Lighting system which merely redirects sunlight, is advantages
as electrical consumption can be reduced. During low light conditions, energy efficient
fluorescent lights and special grow lamps illuminate the building. Therefore there is security as
crops are not weather dependant and can be grown all year round.

X Conclusion
The food security issue is real; it is a threat to national security and should be addressed
at a national level with government support to help increase local food production. Given
the serious land constraints in Singapore, Vertical Farming seems to be the optimal solu-
tion available given the current state of technology.
Although our Vertical Farm is an educational model, we hope the government taps the
true potential of this project, as how the people express (Figure 10.1), to alleviate the na-
tion’s serious over-dependence on imported food, and simultaneously, educating the
public in alternative farming techniques.

Annex 2 - Excerpt of Interview with Ex-CEO of AVA Dr. Ngiam Tong Tau
Purpose1. Find out what types of crops to cultivate which are easy to grow .2. Assess whether this project is feasible 2. Get expertʼs advise and guidance to fine tune the project.3. Expertʼs comments on the degree of success of the project4. Find out which location(s) is(are) the most suitable for Vertical Farming.5. To find out if an expert like him believes that our project can be considered for large
scale uses 6. He, being an expert in his field, and also previously being a person who was actively
involved in the AVA policy making hierarchy, he may still have significant influence over the political leadership, to convince them to put their weight behind, and financially sup-port this proposed project.
7. We also hope to try to convince the expert that perhaps vertical farming may be more economically viable than the Jilin Project. and can possibly save money for the country
8. To tap the expertʼs vast experience in the pitfalls/advantages of farming in general.9. To discover other aspects of farming which we may not have considered.
Bhalraam :
Our whole project is based on Dr Dickson’s idea of vertical farming which he planned in America. We think that it is difficult to plan in Singapore because of the small area and land boundaries. Since Singapore is try-ing to increase local food production, we think that vertical farming is feasible. Our plan of the vertical farm-ing is 9 stories high with base area of 10000 metres square and this will theoretically produce 7.3 million of lettuce. We intend to turn it into an exhibition too. So I would like to ask you what is your overall impression on our project?
Dr. Ngiam:
I think there will be technical problem of growing the crops and there will be a problem of getting sunlight into the building where the crops need certain hours of sunlight. Technically you can solve it by using the optical fiber cable but that will cost a lot of money.
Bhalraam:
We have came up with a sum of money for the vertical farming which I will let you have a look later. Rama has some research on the optical fiber so he can tell you more about it.
Cropping it UP! - Written Report! 40
Dr. Ngiam:
The other thing is that water supply for the vertical farming is also very important as there may not be any water area or connection to supply water and it will be very expensive. Soil is not a problem as there are many kinds of soil you can use whether it is on land or multi-storey. Soil is the same. The logistic of the har-vesting has to be designed such that you can harvest the crops easily if not you have to get a lot of people to harvest the crop.
Bhalraam:
What kind of crops do you think we can grow?
Dr. Ngiam:
Since it is a high cost production system, therefore you need to go for a very high value vegetables crops. If you are going for lettuce, that is alright. Like the aeroponics and hydroponics, it must be light weight so that the structure of the vertical farming will have the strength to hold these things. So there will be a high cost on the structure. If you want to spend less on the structure, you have to make it very light for the structure to hold. To turn it into an exhibition or demonstration in the future where there is no land to farm, people have to pay more for their food. But as a commercial competition, it will be hard to make it into a business as your products have to compete with people who grow their crops on soil as soil is very cheap as compared to ver-tical farming. Singapore’s land is more expensive than Malaysia’s land. Even so, it is cheaper in cost produc-tivity. Technically anything can be solved as it is all depending on the economy.
Bhalraam:
For the vertical farm, ours is the smaller diameter so do we need to consider the optical fiber technology or do we just use glass?
Dr. Ngiam:
Yes, I think for the light, whatever it is, as Singapore is not blessed with sunlight so if there is a roof, the crops below will be blocked from the sunlight.
Bhalraam:
Ok so do you think it is feasible for partial use of optical fibers?
Dr. Ngiam:
Yes I think you should be thinking of using optical fibers although it is of high cost. I have seen factories in Japan doing that. It is better to bring in the natural sunlight which is free rather than artificial sunlight. If not, the operating cost per day will be very high just to run those lights.
Cropping it UP! - Written Report! 41
Rama :
Regarding the optical fibers, the idea is to join it with lighting fluorescent lamp and it will be controlled by a monitored computer system with the amount of sunlight depending on the sunlight conditions. Since the op-tical fibers are only efficient up to 50 feets it will only benefit the top two floors. Due to that constraint, I was thinking of putting them outside the building at each level so that the light will come in horizontally.
Dr Nigam:
Ok, good. But how do you bring the light in?
Rama:
On the roof there is a solar connector receiver.
Dr. Ngiam:
Ok, but you must always remember that plants do not need light all the time, only at certain time. You must make sure about the wavelength of light needed for photosynthesis. It is good to follow the hydroponics and aeroponics system, with 1 crop every 2 months which is 6 crops per annual. If you are growing the temperate crops, you have to cool the water first before supplying it to the crops. You should visit any of the vegetables farms in Singapore to know more about the farming system. Architects are needed to design the building of the vertical farm, engineers to engineer the farm and lastly economist to advise you on what kind of crops to grow at different time.That is how commercial companies do it. The only challenges you will face it how to get sufficient sunlight into the building and the cost of it. You must know your operational cost and the out-puts for the vertical farm. The cost of infrastructure in Singapore is very high as the government wants to make sure that the structure of the building is safe for the people. Scientifically you can do it but commer-cially, there are many challenges you will face.
Bhalraam:
Ok we will take note of that. We also did a survey, tze ling will tell you more about it.
Tze Ling:
Many of the people feel that eating Genetically Modified food is unhealthy. So do you have any comments on why people refused to eat GM food despite it being more valued ?
Dr. Ngiam:
Cropping it UP! - Written Report! 42
It is not that GM food is more valued, it is just that they have not came up with a greater value of GM food and it is cheaper since GM crops are better controlled as they are pest resistance. So chemicals such as pesti-cides are not needed.
Tze Ling:
It the crops are grown in a building, do we still need pesticides?
Dr. Ngiam:
There is no need for pesticides if you manage and monitor the crops well.
Bhalraam:
What about those giant oranges? People feel that it is not safe to eat.
Dr. Ngiam:
People do not know GM food well, so naturally they will think that it is not safe to eat. Only the GM food that are tested several times are safe to consume. The good thing about GM food is that they put in things that are good for our health like nutrients and vitamin A.
Bhalraam:
Do you think we should educate the public about GM food?
Dr. Ngiam:
There is actually a website to know all about GM food. Not everyone knows biology so it will be difficult for them to understand about GM food and that is the barrier. So they need the assurance from the authority like the AVA to tell them whether it is safe to consume GM food I order for them to trust GM food. What is the significant finding in the survey?
Tze Ling:
Yes, we found out that many younger people feel that vegetables do not play an important role in their diet. So should we educate them?
Dr. Ngiam:
Yes, in fact the ministry of health has been doing that.
Cropping it UP! - Written Report! 43
Tze ling:
In this survey, people feel that vertical farming has the chance to succeed. So do you think with the support from these people, the government will see it as an option?
Dr. Ngiam:
Yes, the government will see it as an option but the problem with the government is that there is a lack of private sector. If it is commercially viable they will do it. To turn vertical farming into a business, private sector is needed as government will not give subsidies for food. In other countries farmers are protected un-like Singapore. If vertical farming is economically viable, the private sector will take this idea. For farming, the returns are slow but it has consistent returns. Singapore is not an agriculture country, so we do not have farming background and we need to compete with other agriculture countries with experienced farmers.
Bhalraam:
Which organizations do you think will potentially sponsor us in our project?
Dr. Ngiam:
You can go to the AVA food fund or economic develop board as they like innovative ideas.
Bhalraam:
Why you chose to farm in jilin?
Dr. Ngiam:
Jinlin has fertile lands which made it very suitable to grow crops. As it has a temperate climate, the crops are harvested once very season. The productivity is very high which is due to the fertility of the land.
Bhalraam:
Which parts of Singapore do you think we can build vertical farming?
Dr. Ngiam:
You can actually build it at the parks in Singapore, for example the National park. In this way, it will attract more people to go to the park since they are able to buy fresh vegetables home to cook and this is a healthy lifestyle. Basically, farming industry is no different from any other industries. It will be good if you can lower the cost of production which is almost the same as the cost of production in china so as to remain
Cropping it UP! - Written Report! 44
competitive. The cost of production in china is very low. You have to understand, in just 30 years, Singa-pore’s Local food production dropped from 95% to 7%.
Bhalraam:
Ok, that’s about it. Thank you for your time.
Annex 3 - Excerpt from Interview with Manda Foo from Bollywood Veggies Agricul-tural farmWe felt that an interview with the founder of Bollywood Veggies, Mrs Ivy Singh-Lim would give us good insight as her farm is also a bistro (having both a restaurant and well as a farm) which is implemented in our vertical farm idea. Their farm is also a show farm to show different kind of fruits and vegetables that can be grown in Singa-pore. Upon extensive sourcing and research, we found that Mrs Singh’s farm was the best place to inquire on some pressing questions on the vertical farm. Unfortuntely, we were only able to sit in with Ms Manda Foo who, as she says in the transcript, can be considered as a ‘scribe’ for Mrs Ivy. Thus we were more than satisfied to have her views.

Annex 10 - Modern irrigation methods implemented
Modern irrigation methods implemented
Our case study reveals that high water consumption due to wastage was a catalyst driving
the need to find solutions for water scarcity. Similarly, the lack of land space drove us to think
unconventionally and find ingenious technological solutions to self-sufficiency in the field of
agriculture (Table).

Table : Benefits of Hydroponics and Aeroponics
Technology Benefits
Hydroponics
The growing of crops by using
nutrient solution instead of soil
• Labour cost for manual irrigation is minimised
• Water is conserved, saving more money
• Pests and diseases are eradicated due to the controlled
environment
Aeroponics
The growing of crops by
suspending roots in the air and
having a machine to spray
nutrient water periodically on the
roots
• Labour cost for manual irrigation is minimised
• Plants develop faster as roots are subjected to clean air
• Much less water is used
• ‘Crop to Area’ ratio is increased as more crops can be grown in a
lesser area.
