Food Wastage in Singapore - Think before you throw!

"Hunger never saw bad bread"

Benjamin Franklin

From the Field to the Plate. 

The idea to document the journey of food from the field down the production chain to the plate sounds simple enough, but over the course of this blog, I realize the journey of food goes beyond the plate after it is consumed by the hungry masses. What then happens to food after it gets consumed? Does it get disposed? Or are there ways to recycle food for further use?

In previous weeks I explored how food leaves the production line for fueling vehicles rather than filling stomachs. In this post I bring forward another key controversy in food’s journey to our plates, its wastage. Just like other forms of waste, food is wasted from both production processes and post-consumption, leaving it piled up in landfills and attracts animals and vectors, which see them as sources of food. Vectors in particular carry diseases which can affect the health of the population (Khoo, Lim and Tan, 2010).

Let’s begin by showing some statistics from Singapore over the past few years:

As of 2013, there has been a 17.4% increase in food waste in Singapore, reaching an all-time high of 796,000 tonnes
(Source: Siau (2014); Sim (2014))

As evidenced above, food waste in Singapore has grown tremendously over several years, without any improvements to recycling rates. Wasting of food can be observed by 4 main stakeholders, households, supermarkets, food factories and finally restaurants, each having their own reasons for throwing food away. Households are conscious of expiry dates and dispose of food, while supermarkets might throw away food if it doesn’t look aesthetically pleasing enough. Restaurants in particular are in conflict, as the National Environment Agency mandates catered and pre-packed food to be consumed by 4 hours (App2.nea.gov.sg, 2013).

The problem of food waste however, has not gone unnoticed and considerable efforts have already been made by the government. Singapore has established a working group with representatives from multiple governmental agencies targeted at addressing food waste, and have recently commissioned a survey to understand the food habits of Singaporeans. The press has also presented headline articles highlighting the shocking statistics and similar tips (see TODAY or The Straits Times).

Role of Society and Business in addressing the Food Waste Problem

Non-governmental groups have also been in action. In ENV1101, we looked into the importance of environmental grassroots around the world in driving policy changes. In Singapore however, it is rare to see such extreme environmental activists in action. Rather many present themselves as educators, hoping to rally the masses to collective action. This is no exception to food waste, an emerging issue in the field of environmental sustainability. Mr. Eugene Tay, founder for Green Future Solutions, pioneered the first food waste related website “Save Food Cut Waste”, which highlight tips for users to minimize their food waste. 

The push to tackle food waste has been done across multiple sectors, sometimes as collaborations and others individually. Above are some of the organisations working towards a Singapore with minimal food waste

Youth and NGOs have also been involved in this struggle. In 2013, a group of Mass Media students from Nanyang Technological University launched Makan Mantra for their FYP, a campaign to teach people steps to reduce food wastage when dining out, a common trend amongst working Singaporeans (learn more about their campaign here). NGOs such as the FoodBank and Food from the Heart, were also founded by individuals keen on making a difference into the lives of the needy, who had very evident difficulties in procuring food. The impacts these stakeholders have made to the F&B industry is evidence that so long as a problem concerns you, small groups can have the power to be the change we want to see.

Inspired by what they observe in Singapore, advocates take unique approaches to reduce food wastage. Makan Mantra (top) worked towards educating people on ways to make ideal food purchases, whereas FoodBank SG (above) used a social enterprise model to re-direct food that would have been thrown away to the needy instead
(Source: http://www.beermarket.com.sg/makan-mantra/; http://www.foodbank.sg/banking-differently/how-it-works)

Beyond actions taken by the public, some businesses have also been active in trying to cut down on the food waste they produce, either from re-distribution of food, or from the use of mature technologies to recycle food. One case study in particular impresses me, and that would be Marina Bay Sands, one of Singapore’s Integrated Resorts.

What does Marina Bay Sands do with all the uneaten food after an evening of buffets!

(Source:: http://www.feveravenue.com/chocolate-affair-at-marina-bay-sands/; http://www.marinabaysands.com/restaurants/buffet.html)

Because of their countless buffet options situated at their Casino, restaurants and Convention Centre, Marina Bay Sands collaborates with Food from the Heart to redistribute unconsumed bread to the needy after breakfast buffets close. They also use Eco-Wiz digesters, which convert food waste into re-usable water. Although I could not find a video explaining the green strategies of Marina Bay Sands, I did manage to find a video on how this Eco-Wiz technology works.

However, just having these technologies available should not justify excessive production of food by companies, for that is also a means of depleting resources unnecessarily. Also, the degree to which businesses can afford these technologies really depends on their finances. While bigger companies can invest in such technologies to go green, I am of the opinion that governments have to provide more to support food recycling in smaller F&B businesses like cafes, who are usually hampered by equipment costs, as well as areas of high human traffic, such as hawker centres. This can be done by funding areas with trial systems to allow for recycling of food.

Food waste is a controversial issue, and I feel it is a reflection of modern society’s insistence that everything can be thrown away and the environment will somehow make it magically disappear. Food today has become a lot easier to assess, and people seeing this would likely argue that throwing away a small portion of their plate that they couldn’t eat finish would probably do themselves. However, little actions do add up, and creating such unnecessary waste streams would result in greater environmental problems than people can imagine.

Let us be considerate for the environment.

Biofuels (Part 2) - Exploring Innovations for ASEAN

"Biofuels... it's already had one life and now it's going to be used again, which is nice"

David Hannah

In my last post, I have explored the significance of biofuel production in the ASEAN region, as well as established that there are food security challenges that will be faced in trading off food crops for biofuel production. In this post, I shall be exploring two topics pertaining to biofuels, firstly in feasibility of using biofuels as an energy source in Singapore, as well as global innovations in biofuels to address food security issues that can be learning points for ASEAN. 

This comic sums up the controversy that biofuels take away food from the hungry and uses it to feed our transportation vehicles instead
(Source: http://www.inkcinct.com.au/web-pages/global/global-social-general/2008--global-social-general.htm)

Biofuels in Singapore

While Singapore is in ASEAN and is the leading oil trader in Asia, biofuel produced here constitutes less than a percent of Singapore’s energy production (eia.gov, 2014), a measly droplet as compared to other ASEAN countries. Almost all of that is exported out as well. Some reasons for this lack of development of the sector was suggested in Mukherjee & Sovacool (2014)’s report, which highlights on sustainability issues in palm oil production. Singapore lacks land space to produce enough crops to convert into such fuels. Being a low-lying equatorial island also prevents us from crops which grow better in hilly terrain and cooler climates to the industry’s development. Despite our inability to grow as much food crops as compared to our neighbours, Singapore’s strong economic presence in the region still draws investment from MNCs for biofuel production, with some of the world’s largest biodiesel factories based on Jurong Island (for more info see here). Food crops are then imported from our regional neighbors

Singapore has been exploring our biofuel capabilities. Biodiesel usage is presently in the testing stage for domestic households, in the most unlikely of places, an offshore island we call Pulau Ubin. The island might house few houses and even fewer residents, but it’s presently the test bed for an alternative energy grid combining solar energy with biofuels to power generators, supplying electricity for businesses and households in Ubin Village. Driven by the Energy Market Authority and Daily Life Renewable Energy, it has addressed an age-old problem for business owners and residents who previously had to source for diesel from the mainland on a daily basis. (for more information visit here)

Solar panels decorate the rooftops of buildings in Ubin Village and generators are placed in secure control rooms fueled by biodiesel produced from the mainland

(Source: http://www.todayonline.com/singapore/biofuel-driven-energy-grid-launched-pulau-ubin)

However, whether this successful test-bed can be scaled up to cater to the needs of Singaporeans is entirely another matter. As compared to Ubin residents, Singaporeans would have higher living standards and a greater demand for electricity. This would make biofuels less feasible as it still has lower energy efficiency as compared to conventional fossil fuels, the current fuel of choice for Singapore’s electricity production.

Global Solutions for ASEAN

On a global level, both developed and developing countries show increased utilization of biofuels. However, biofuels’ main controversy remains to be that food crops, which can be used to feed the hungry and improve food security, are being used to fuel the push for biofuels instead, causing food prices to rise unnecessarily. In 2007, the export of US corn to Mexico was minimized to support corn ethanol production in the US. This raised the prices of tortillas, a Mexican staple, by 25%, sparking off the ‘Tortilla Riots’ and strained bilateral relations (for more information, read here).

(Source: Wise, 2012)

7 years on, scientists have made progress to improve food security across the world, with the emergence of second-generation and third-generation biofuels. Both of these fuels are made from non-edible biomass, which makes them not in direct competition for consumption. However, second-generation biofuels still require many of same agricultural resources, such as land and fertilizer, as first-generation biofuels, making them still in direct competition to food crop production (Koizumi, n.d.). There are notable exceptions to this, such as jatropha, an emerging biofuel which can grow even in infertile soil, such that it can be grown by farmers on non-arable land. This Deutshe Welle article sums up some of the unique features and possible challenges that jatropha cultivation faces in developing nations.

Microalgae is another heavy contender for being a mainstream energy source that is still under research. Storing energy in the form of natural oils, solvents are used to break down the cell structure of microalgae and the oils are extracted subsequently. This third-generation biofuel has the potential to produce up to 60 times more oil / acre than land-based biofuels. In addition, being grown in an aquatic environment, it does not compete for resources with land-based food crops, being able to be cultivated even in urban areas. Given these benefits, the US Department of Energy has recently allocated 25 million USD into the further research of microalgae, so as to lower its costs and become more viable for commercial production. It has also began educating the public, releasing this video below to highlight the potential of microalgae cultivation to solve energy problems in the US:

These biofuel innovations however are still not being explored much in the ASEAN region. Policymakers might be most wary of the high production costs. According to the Committee on World Food Security’s (2013) report, the production of second and third-generation biofuels can cost many times more than the conventional biofuels being produced at present. To lower the start-up costs, further R&D might be needed by the scientific community before the ASEAN region can properly consider relying on these forms of biofuels instead.

A comparison of the production costs for different types of biofuels. Evidently microalgae can cost more than 400 times the cost of producing first-generation biofuels like maize (US) 

(Source: Committee on Food Security (2013))

In addition, introducing these innovations might distort an existing status quo, whereby there are presently strong partnerships between existing biofuel companies, the farmers who produce these crops, as well as the government. (Kumar, Shrestha & Abdul Salam, 2013). Transitioning to second and third-generation biofuels might actually have harmful economic implications as this creates competition. This could result in undesirable outcomes such as job losses, energy insecurity and even civil unrest. Should these barriers be addressed however, the future for biofuels in the region could be very bright as it will addresses energy and environmental problems all at once, but more importantly still allow food to reach the plates of all.

Biofuels in ASEAN - Energy Opportunity or Food Thief?

"Do you know what my favourite renewable fuel is? An ecosystem of innovation."

Thomas Friedman

Renewables guru Per Dahlen once commented that Southeast Asia has the potential to produce 14 million barrels / day, which is more than Saudi Arabia (For more info, visit here). However, what will unlocking this potential cost the region? When I encountered this statistic, one disturbing idea that came off my head was the diversion of edible food crops away from the plates of citizens into machines guzzling out fuel by the barrel, or plots of land that could be used for the growth of food to be eaten being taken away by big businesses to grow biofuel crops instead. Classified into ethanol and biodiesel based on the crops used (ethanol uses starchy crops, biodiesel uses natural oils), biofuels remain a controversial topic across the world and while I have been interested by food vs fuel debate, I have never actually looked into it in-depth. Well, today that ends!

In our search for alternative fuels, have we forgotten biofuel takes land away from subsistence farmers and food away from the hungry?

(Source: http://globalenergyscenario.blogspot.sg/)

To learn more about the importance of biofuels in the ASEAN region, I will be discussing 2 journal articles that I have read over the week. One article (A review of biofuel policies in the major biofuel producing countries of ASEAN:Production, targets, policy drivers and impacts) covers trends and motivations for biofuel production and usage in 4 countries, Malaysia, Indonesia, Thailand and the Philippines, whilst the other article (Palm oil-based biofuels and sustainability in SoutheastAsia: A review of Indonesia, Malaysia, and Thailand) zooms in on palm oil biodiesel and the environmental considerations that are concerned with biofuels, using Indonesia, Malaysia and Thailand as case studies.

Evidence from both articles suggest biofuel production is a rapidly growing energy sector in ASEAN. With the flexibility of biomass to supply both heat and power, we observe more food crops such as sugarcane, palm oil and cassava being grown, only to be used to produce biofuels (Kumar, Shrestha & Abdul Salam, 2013). Below are graphs showing indicate the steady upward trend for production of biofuels in the region (except Malaysia, which has decreased)

Graphs show steady increases in production of biofuels in the ASEAN region 
(Source: Kumar, Shrestha & Abdul Salam (2013))

Both articles also suggest that governments in the ASEAN region support biofuel development despite the potential environmental costs. The biofuel industry is defended because it provides greater energy security by relying less on overseas sources and creating jobs for their citizens. Although the burning of biofuels is also determined to release far less CO₂ emissions than conventional fossil fuels, concerns for the environment are highlighted in Kumar, Shrestha & Abdul Salam (2013)’s report to be less of a driver for most ASEAN countries, as they are not required to lower their emissions under the Kyoto Protocol. In fact, environmental problems have stemmed out in recent years from palm oil production instead, such as excessive deforestation and transboundary haze (Mukherjee & Sovacool, 2014).

While biofuels can resolve energy insecurity and even lower greenhouse gas emissions, instances of environmental degradation, biodiversity loss and poor air quality remain a primary concern amongst environmental groups and governments. 

(Source: Watts, 2011; Chua, 2014)

It is not wrong for policymakers to be considering the energy needs for these rapidly developing countries, but my biggest qualms after reading these two reports is whether alternative energy production should be the biggest priority, considering food security for many citizens in these countries fluctuates fairly often. Many people in these countries live below the poverty line, and rely on subsistence farmers for their food. However, the diversion of food crops away from markets has made prices rise, causing even more economic pressures for citizens who choose to grow hungry to afford other daily necessities such as rent. Majority of biofuels in ASEAN aren’t even used domestically, rather it is exported out to Europe and North America (Kumar, Shrestha & Abdul Salam, 2013), where the demand for biofuels has risen drastically. This makes it more controversial, as this suggests that the motivations for ASEAN countries to produce biofuels are economically driven to the production demands of more developed nations, rather than their own personal needs. Given biofuel is not a unique good to ASEAN and can be grown in other areas, what comes across as a simple business transaction between producer and consumer might actually be an outsourcing of environmental costs by developed regions to lesser developed nations so as to create opportunity for higher value services to be established in their own regions.

Biofuels seems to present itself as an emerging alternative energy in the region from the reports, but little breakthrough has been made at a national or regional level to ensure continued food security in ASEAN, suggesting that in the eyes of our policymakers, biofuels will always result in a trade-off. Is this necessarily true? Or is there that magical win-win situation for this food vs fuel debate? In my next post, I shall stay on the topic of biofuels, focusing on their production and usage locally and globally, as well as explore innovations in the biofuel industry that have addressed food security.

Green Space Conflict(s): Bringing in the Animal Perspective (Part 2)

“The Clearest way into the Universe is through a forest wilderness.”

John Muir

In this continuation from my previous post, I will resume looking into food sources for animals, but focus on what happens should their food sources disappear.

Food is one of the most important necessities for any organism, being sources of energy and essentially necessary for organisms to survive. For animals, almost all their food originates from the natural environment. However, as explained with my last post, natural environments all around the world are experiencing increased stress, coming as a result of changes in human needs such that more resources are required, and less is left for animals to consume.

Singapore today is driven to develop not by the need for food, but the need to address an increasing population (which has grown by 1.6% in 2013), brought about by both natural increase and by in-migration (Population Trends 2013, 2013). As commented by various authors writing on Singapore history, to create more space to house people in urban environments, development has come at expense of existing forests, which would get deforested. Flora and fauna residing in these forests then either get chased away to other nearby forests, or die because they lose their food source and habitat (Chong, 2010; Wong, Yuen and Goldblum, 2008).

“Our metaphorical hunger for space leads us into eating our forests” 

(Source: http://www.cartoonmovement.com/cartoon/1173)

Perhaps the bigger question to ponder about is where these animals will go for their food should green spaces in Singapore dwindle with time? As our small island geography makes many animals unable to leave, one extreme end of animal adaptation stems from this satirical video I have found online, as a polar bear is depicted to be adapting to the city’s lifestyle. 

A more probable scenario would be animals searching for food from human environments. Termed as urban wildlife, the residential areas of cityscapes presents many sources of food for fauna, ranging from fresh food stored in homes to garbage left outside for disposal (Cecil, n.d.). In Singapore we might be familiar with crows and pigeons taking shelter within our HDB flats or hawker centres, but one particular story I would wish to highlight would be the tale of macaques, monkeys residing in our Bukit Timah and Central Catchment Reserves.

Long-tailed macaques – once peaceful dwellers of our reserves, now the latest inhabitants in our neighborhoods
(Source(s): http://mygreenspace.nparks.gov.sg/long-tailed-macaque/; http://travelfish-sg.s3.amazonaws.com/)

Just a year back, these creatures were portrayed as pesky villains as they pillaged nearby homes and were rumored to have attacked peaceful trekkers, leaving much complains and calls for their culling to restore peace for homeowners living near forests (for more info click here). However, this came under fire by the online community, who believed that the encroachment of such property near wildlife habitats suggests that homeowners had it coming, and rather than merely calling for their culling to solve their problems, they could have found ways to integrate monkeys into their home environment. However, it is becoming easier to suggest such reductionist approaches, whereby little care for our surrounding biodiversity is justified by our own circumstances of scarcity.  

Scarcity however, can be an impetus for innovation in Singapore as well. Mentioned in URA's Master Plan (2014), many places in Singapore today are planned with the intention to serve multiple purposes. Green spaces are no exception, with many being used as recreational sites and some even seek to educate visitors on our historical past. (NParks has a list of parks based on their secondary purpose, to learn more click here). This way, flora and fauna in these forests and parks do not necessarily lose their home at expense of human development. 

Labrador Nature Reserve, situated at the southwestern shores of Singapore, combines nature with history, showcasing remnants of our colonial and ancient past, yet also being a hangout for human recreational activities, such as fishing. 

(Source(s): http://en.wikipedia.org/wiki/Labrador_Nature_Reserve; Choo Yut Shing (2008) - https://www.flickr.com/photos/25802865@N08/sets/72157606775753395)

Such seems suggestive of an Environmental Kuznets Curve set into motion, where Singapore has grown to consider more for its environment once living standards and income per capita has improved. However, innovation alone will be but a means to buy time, and measures to promote environmentally friendly development strategies have to be in place as well, to recover our green spaces even if it leads to human inconvenience. One such strategy being considered in Singapore is the clear demarcation of man-made environments from natural environments, which would be left untouched. This was recently discussed on TODAY (2014), whereby nature groups in Singapore have called for ‘buffer zones’ to be created between man-made environments and natural ecosystems, relating this to the upcoming development into the Mandai area, one of Singapore's few remaining forests. (for more information see here).

In my opinion, the human populations of today might have made much progress, but even this does not entitle us to have complete ownership of our environment's remaining resources, just because we possess greater intelligence. If anything, we need to develop greater stewardship for our environment, precisely because our intelligence would allow humans to have life-changing impacts onto our environments. While animals have no voices that can be comprehended by us, let us have the courage to be their voice, to be morally responsible for them and factor our rich biodiversity into our planning better. The sooner we embrace the reality of co-existing with them in the same ecosystem and environment, the better we will fare for our future.

From MacRitchie Nature Trail: Bringing in the Animal Perspective (Part 1)

"The good man is the friend of all living things"

Mahatma Gandhi

On what was a breezy and warm Sunday morning, I had the opportunity to go on a nature walk along MacRitchie's Prunus-Petai Trail with BES's very own Drongos, a guiding interest group featuring awesome BES seniors! (find out more about what they do here!!!).

A breezy Sunday - taken just before the start of the walk

A relaxing walk of ~2.5hrs, the focus of this series of walks is to educate others on the biodiversity present in Singapore's nature reserve, and the impending threats they face should the development of the Cross-Island Line proceed. (to learn more about the saga, follow the Love MacRitchie movement here)

What got me thinking was when my guide, Judy, started to talk about how the fruits and flowers of plants along the boardwalk were food sources for wildlife residing in the area. Hearing her prompted me to think about my entry for this blog.  

BES Drongos after their guiding session!
(Source: Jacqueline Chua (14 September 2014))

My blog content has presently been focused on the challenges of fulfilling human needs. But food isn't a need exclusive to humans. Aren't animals (and by extension of that idea biodiversity) part of this bigger picture? Don't they need food too and just where do they get their source of food from in Singapore? Do animals and other forms of biodiversity in Singapore have sufficient food sources to feed on?

Reports and studies indicate that Singapore is a sanctuary for many species of wildlife. Our tropical climate and multiple habitats (ranging from coastal mangroves to inland forests) lead to more forms of biodiversity in comparison to temperate and arid environments (Laurance et al., 2012). So what would these species do to procure food then? Obviously they don't visit the supermarket or the food court like we do (just imagine the social trauma people would experience should a monkey order a bowl of noodles; that'll make us all go bananas!), rather they source their food from where they live, climbing trees, entering water bodies, even foraging through the soil for smaller animals, plants and nuts to feed on.

Let me share some pictures of plants I have taken today, which are actually food sources for animals residing in the Prunus-Petai Trail of MacRitchie:

The first picture is of a Fishtail Palm (Caryota mitis). This palm's fruit is one of the foods for the common palm civet (Paradoxurus hermaphroditus)

The next one features the Common Marang (Macaranga bancana). The plant produces food for the ants, in the form of "Beccarian bodies", which are rich in lipids. In return, the ants protect the plant from prospective herbivores that might try to feed on it. 

The 3rd picture shows the Mousedeer plant (Anisophyllea disticha). Found in lowland secondary forests across the region, the fleshy red drupes produced by the plant are known to be eaten by birds, as well as the lesser mousedeer.

This last picture is the Tampinis tree (Streblus elongatus). Having a neighbourhood (Tampines) named after it, birds and squirrels are known to go after the sweet tasting fruit, whereas Long-tailed Macaques feed on their leaves as well.

Not featured (due to a lack of pictures) but also known to bear fruit are the Nibong palm, a palm with prickly needles on its stem to deter climbers (Oncosperma tigillarium) as well as the Golden Hairy Figs (Ficus aurata), a longan-like fruit in terms of its shape.

As a whole, while humans have historically been caught in strife and wars, animals seem to live their lives in peace in comparison, sure a few get eaten by others and by humans, but that's part of natural selection in action. Humans have also lived off these forests and this is continued by many ethnic tribes all around the world, such as the Batwa (which was mentioned briefly during my ENV1101 lecture). In fact, National Geographic published an article last month discussing about the interconnectedness behind human health and environmental health from assessment studies done in Madagascar. 

However, human needs seemed to have changed and drastically increased with the advancement of technology and society as a whole over these past 50-60 years. Termed the 'Great Acceleration' by some in the scientific community, we observe a sharp increase in development and urbanization across the world (Steffen et al., 2011). This is also rather evident in Singapore, where we have progressed tremendously from Third World to First, but also transformed from forest to urban jungle, losing much of our original forest cover. With our increased demand for natural resources on a global level, the availability of these resources will deplete in the future, and could be an indication of the environment reaching its carrying capacity, which is suggested in a Malthusian model for population-resource relationships. 

Comparing forest cover from 1819 to the 1990s, it is suggested that Singapore has lost close to 90% of its original forest from rapid development (Source: http://mangrove.nus.edu.sg/guidebooks/text/1004.htm) 

In this light, I would talk more about (in my subsequent post) what happens when human needs and the needs of animals residing in our natural environments clash? What happens if animals are no longer able to get their food, and what conflicts arise in satisfying human needs.

Stay tuned for the next post! And here are two more pictures of what you might be able to find during the trail, do visit Prunus-Petai Trail if you can!

Greening Singapore, why not Feeding Singapore too? - Food Gardens

“If you have a garden and a library, you have everything you need"

Cicero

Let me begin today’s post by sharing you this video:

Given this blog title is ‘From the Field…’, it feels strange to me on how little of the agricultural sector (i.e. the field) we see in Singapore, strategically placed away from the residential and CBD areas. Listening to Ron Finley’s inspiring story of creating a food garden movement in his city, I felt compelled into writing my views on the potential of food gardens within our neighborhoods, whether it is possible to begin with and the challenges we might face.

Singapore has a rather friendly environment to grow food and spices, given our agricultural history. Think about Orchard Road, Singapore’s shopping street, but named for previously housing plantations for nutmeg, pepper and other spices. We are in a geographical favorable location for biodiversity. While we lack seasons, our tropical climate and lack of environmental hazards such as floods and drought (Rosenzwelg and Parry, 1994), allow for a multitude of vegetables and fruits to grow, such as kang kong and tomatoes.

What about the costs of planting your own fruits / vegetables then? Beyond the investment of time (weeks, sometimes months) required to tend the plant(s), gardening can be a rather cost-efficient activity too. A gardening shop in Singapore would sell seeds at $5 for a pack of 50 seeds and gardening tools can be purchased at a hardware store such as Home DIY. There is also a need to consider for compost and fertilizer, but you can always DIY that with your food scraps (if you cook). Just go to YouTube or Google to search for countless of methods. Here’s one which utilizes egg shells which I found fascinating!

You don’t necessarily have to have to own a plot of land to begin growing your own food either. There are many groups around Singapore that have a keen eye for gardening, and this is further supported by the National Parks’ Board ‘Community in Bloom’ initiative, which allows Singaporeans to contribute to the green ambiance in Singapore’s neighbourhoods (NParks, 2013). Below are some resources to learn more about gardening in general and food garden projects currently existing in Singapore.

“Edible 'Garden City' Project” -
One of the most prominent groups championing the 'Grow Your Own Food' movement in Singapore. They conduct consultations for F&B outlets and homes, as well as workshops on how to grow your own vegetables

“Green Culture SG” -
A forum to for local gardeners to share their knowledge and discuss about gardening. (link goes to the sub-forum on Edible Plants)

“NParks Gardening Resource Websites” -

NParks' very own resource list comprising of videos, websites and tips on Gardening

The hard truth is that we will not be able to get everything out of these gardens, and the role of markets will remain central in the lives of Singaporeans as a way to get a bulk of their cooking ingredients. Nonetheless, food gardens can have multiple purposes as well, becoming a new recreational space for communities, and more importantly provide an opportunity to bring the public closer than ever to appreciate food coming straight from the field, rather than off the shelf.

 

Just last month, over 350 community-run gardens under the Community in Bloom Programme were awarded prizes during the Singapore Garden Festival. Featured above is from Woodlands Zone 2 RC, a Platinum and Diamond award winner. Their food garden grows plants such as pandan and chilli which are condiments in cooking

Gardens can be beautiful. Why not eat off them every now and then too?
