The school received an environmental subsidy of NT $220,000 two years ago to plant large Dumbo flowers to form a green wall, which helps to cool down the temperature and purify the air, and also to install an automatic sprinkler system to maintain the ecology of the green wall.
According to the Environmental Protection Bureau of Chiayi City Government, since 2019, the Environmental Protection Department has promoted the vertical air green wall project. Since 2019, three schools, including Xingjia, Jiabei Elementary School and Jiabei Elementary School, have installed climbing plants on the school's daughter wall and the balcony of the classroom.
The Environmental Protection Bureau of the Chiayi Municipal Government said that this year, the Environmental Protection Agency expanded the target of subsidies, in addition to the original subsidies of public middle school, public elementary school, public preschool institutions, public welfare groups, public facilities, environmental protection night market, civic activity center and other venues, air green wall subsidies of 3,000 to 6,000 yuan per square meter, single subsidy ceiling of 400,000 yuan.
According to the Municipal Environmental Protection Agency, according to the results of the study, vertical green walls can reduce the concentration of nitrogen dioxide (NO2), suspended particulates (PM10) by about 40% and 60%, but also reduce the concentration of indoor fine suspended particulates (PM2.5) by about 10%, ozone by about 30%, and indoor temperature reduction by about 1.8 ℃.
According to the city's Environmental Protection Bureau, the appropriate plant types are lily bamboo, firecracker red, Yunnan yellow carnation, turtle, Boston kidney fern, hydrangea, African pansy or panthera, and can be selected according to the space planning and installation requirements, so that the space is more beautiful.

Content: In order to improve the environmental air quality and let children learn with peace of mind, the Taichung Municipal Environmental Protection Bureau has continued to build a clean air green wall in the school. This year, 12 schools in Jianping Elementary School, Juren Elementary School and Chongde Elementary School have received subsidies from the Environmental Protection Department.
According to the Environmental Protection Bureau, through the installation of clean air green walls, indoor air quality can be improved. At present, space such as classroom corridors and flower stands outside the daughter wall in Taichung City can be planted, which can achieve the benefits of dust retention, air pollution absorption and temperature regulation.
In order to strengthen the protection of the school environment for children, the Taichung City Environmental Protection Bureau expanded the subsidy for the construction of a clean air green wall on the campus, and the current subsidy amount to 1.76 million yuan, with an area of 358 square meters.
The Environmental Protection Bureau stressed that currently selected plants that can purify the air and do not need to spend too much money and time to maintain include the Dragon Tubeh, the Junzi and Wu Bamboo, the Turtle, the Cannonflower or the Honeysuckle.
How good is the effect of clean air green wall?
According to international research, vertical clean air green walls can reduce the concentration of nitrogen dioxide (NO2) and particulate matter (PM10) by about 40% and 60%. In addition, green walls can also reduce the concentration of fine particulate matter (PM2.5) in classrooms by about 10% and the concentration of ozone (O3) by about 30%.
Green wall is the most natural and energy efficient air purification facilities, no need to plug in electricity, self-circulation, to achieve the purpose of air purification, can be called the "most environmentally friendly air purifier".
Chen Hongyi, director of the Environmental Protection Bureau, said that in addition to blocking outdoor pollutants and improving indoor air, the air green wall can also adjust the temperature and drive energy conservation and carbon reduction. Next year, Taichung City is expected to expand the subsidy target, including community activity centers, public kindergartens and environmental night markets.

Recycling of Microalgae Water for Feed to Create a Circular Economy
[Ming Pao News] Microalgae microorganisms occupy small space, grow fast, photosynthesis is strong, and have a certain nutritional value, and in the increasingly high demand for environmental protection, in recent years more and more attention.
Some local enterprises began installing “microalgae reactors ” for the government and enterprises a few years ago, initially to improve indoor air quality, as well as as carbon reduction projects and green decoration, and later developed into the supply of microalgae powder to local lobster farms to add to the feed.
Ming Pao reporter Xue Wai Kit
Photographer Yang Po-hsien
Greentins Horticulture founder Tian Cheng-hui said that the company was founded in 2005, originally to represent foreign waste wood and plastic made of "green wood". In 2011, the company began to install a "soilless green wall" for enterprises to grow plants indoors, on the one hand, can green the indoor; on the other hand, can absorb carbon dioxide. I) Collaborate on the development of "Microalgae Reactor".
Simply put, this is a container filled with water to cultivate microalgae, but in order to enhance the photosynthesis of microalgae and maximize their ability to absorb carbon dioxide and release oxygen, the microalgae reactor is also equipped with adjustable LED lights, and constantly pump indoor air through the air pump to let the air pass through the water for cultivating microalgae.
Microalgae reactors in offices help reduce carbon
Optimized with 50 liters of microalgae water, the microalgae reactor can remove up to 5,500 kg of carbon dioxide per year; 1 cubic meter of microalgae water is more efficient than 100 square meters of forest.
Therefore, if you need to offset the amount of carbon dioxide emissions, installing microalgae reactors in the office is much easier and simpler than traditional tree planting.
In addition, it can also improve the air quality in the office and help improve the efficiency of employees.
Because many studies have pointed out that the carbon dioxide concentration in the air in a good office environment should be between 400 and 800 ppm; if the carbon dioxide concentration is between 800 and 1200 ppm, employees feel bored and tired.
Reduced CO2 levels increase employee productivity
However, when the microalgae reactor was launched in early 2019, the response of enterprises was lukewarm.
On the one hand, some companies do not know much about microalgae; other companies feel that the cylindrical pipe appearance of microalgae reactors is difficult to cooperate with indoor decoration.
Fortunately, the company attracted the attention of the FEHD when it participated in a seminar and exhibited microalgae reactors in the Science Park.
Subsequently, the FEHD installed microalgae reactors in two public toilets, followed by the Electrical and Mechanical Services Department's Kowloon Bay Headquarters.
In addition to the increasing pressure on large enterprises to publish the ESG (Environmental Protection, Social Responsibility, Corporate Governance) report, the company also provides an additional option to combine microalgae reactors and soilless green walls to beautify their appearance, and finally attract corporate inquiries and procurement.
In September last year, the company ’ s microalgae reactor was recognized as a “negative carbon emission ” environmental protection device by the Certification Center of the Chinese Manufacturers ’ Association of Hong Kong, meaning that it removes far more carbon dioxide than it emits.
According to their experience, the carbon dioxide concentration in the indoor air in local offices is usually over 1000ppm, which is a high level.
In general, the company recommends to customers that the number of microalgae reactors purchased should be sufficient to control the CO2 concentration within 800 ppm.
As of June, the company ’ s microalgae reactors have been installed in more than 20 indoor venues in Hong Kong. For the time being, government departments are still the sector with the largest number of purchases.
However, the construction industry has also had a lot of enquiries recently, and it is likely to overtake the government departments in the future.
Some construction companies have expressed their intention to hire multiple sets of microalgae reactors to be placed on the site during the construction period in the future to offset some of the CO2 emissions.
The biggest recent breakthrough was the supply of microalgae powder to Chien Kuo Seafood, which was added to its synthetic lobster feed.
Tian Cheng-hui revealed that because the microalgae in the microalgae reactor will continue to multiply, the number of microalgae will increase rapidly, causing the microalgae water to gradually become dark.
Therefore, the company will regularly go to the door to recover the old microalgae water, and replace it with new water and microalgae for customers, about once a month.
As for the old microalgae water, it will filter the water, and then squeeze, dry, sterilize, and crush to become a dry microalgae powder.
In the past, the company mainly added microalgae powder back to a small amount of water to make a liquid fertilizer for soilless green walls.
Chien Kwok Seafood ’ s founder Lin Pi-hsia said that the company has a seawater fish and lobster farm in the Yung Shu Au fish and shrimp farm in Sai Kung, covering an area of tens of thousands of square feet, which is one of the very few seawater fish farms and lobster farms certified by the World Wide Fund for Nature (WWF). It is currently the only breeding ground for lobsters.
She pointed out that lobster protein content is much higher than sea fish, so its nutritional needs are also diversified. They are usually given different feeds daily, such as small fish, green mouth, shell, oysters, etc.
The company last year designed a synthetic lobster feed that was fed every four to five days as a nutritional supplement.
Microalgae contain protein at affordable prices
When they heard Tian Cheng-hui ’ s proposal, they also felt that there was some reason, because microalgae contains certain protein and microalgae oil, and microalgae powder is affordable, which is also in line with the concept of low carbon, environmental protection and circular economy.
Therefore, the company began to include microalgae powder as one of the ingredients in its synthetic lobster feed design earlier this year, which also helps to reduce the overall cost.
In the future, the company intends to gradually test the inclusion of microalgae powder in some marine fish feed, especially when some fish eat high-priced feed imported from Taiwan. If the use of microalgae powder can reduce the amount of imported feed, it will help to improve cost-effectiveness and reduce carbon emissions.

Hobby or small-holder farmers: Vertical farming may be the way to go

By 7 min read

aquaculture-5990470_1280

Stackable planters can be purchased from local hardware or nursery suppliers to create your own vertical farm.

The need to optimise farming and improve yields on small plots of land is increasingly important. Due to challenges of water scarcity, limited arable land and high inputs costs, innovative solutions such as vertical farming can help to overcome these struggles.

Vertical farming is an approach whereby farmers cultivate certain crops vertically in stacked layers, in order to maximise space and increase yields. This is usually achieved by planting these crops in containers, structures, or stackable pots.

Most often, these structures incorporate aquaponics, hydroponics or aeroponic techniques. All of these are methods used in controlled environments, with various factors such as the water flow, lighting control, temperature, and substrate controlled by the farmer, unlike traditional farming practices.

Vertical farming has many benefits

The most obvious benefit of vertical farming is maximised land use. This method allows farmers to grow more crops in a smaller footprint, making it ideal for areas with limited land availability. But there are other benefits too:

Production throughout the year: Since the environment of vertical farms are more controlled, it is possible to cultivate a crop more than once a year, or to ensure that you have a consistent yield throughout the year – depending on the crop type of course. Any seasonal constraints are removed and production is more efficient.

Water conservation: Less water is used in these systems.with only the precise amount of water needed to provide the plants with sustenance. Where farms are located in greenhouses or indoors, less evaporation also occurs.

Low environmental impact: When less space is needed to grow more food, there is a lower impact on the environment. Less natural vegetation needs to be cleared to accommodate soil based farming.

Improved control over growing conditions: When coupled with greenhouse systems, factors such as light intensity, temperature and humidity can be regulated. However, the plants are more dependent on the farmer to provide nutrients as there is little to no soil used as a substrate. Farmers can exercise strict control over when which fertilisers are used.

How to start a vertical farm

If you are looking to start a vertical farm, you need to first allocate space. You will need a space to put up the vertical structures where it has ample natural light, and where the structures can be safe from animals. People often want to put vertical gardens in warehouses and storerooms, but it is very costly to provide enough artificial lighting to try and make up for the lack of sunlight.

If you plan on adding ventilation to a greenhouse, temperature control systems or any other high tech additions, remember to consider access to electricity or solar power. If solar is your choice, take note the for every hectare of artificial lighting you may need up to five hectares of solar panels to provide enough electricity.

There also needs to be a space where you can add drainage so access water can drain from your vertical farm.

Next, you will need to look at the crops you would like to grow as this will determine  your growing method.

Structures for vertical farming:

Vertical wall gardens

Vertical wall gardens are one of the simplest and most cost-effective ways to start vertical farming in cities where you have walls, and limited horisontal space. You can use recycled materials such as old pallets, wooden crates, or plastic bottles as planting containers. These containers can be attached to a vertical frame or wall, creating a vertical garden. This method is excellent for growing herbs, small vegetables, and even certain fruits like strawberries.

Tower gardens

Tower gardens are vertical systems that allow plants to grow in stacked layers. PVC pipes can be used to create vertical planting towers. Plants are placed in holes drilled into the pipes, and a water and nutrient solution is circulated through the system. PVC pipes are relatively inexpensive and can be found at local hardware stores. Tower gardens are suitable for growing a variety of leafy greens and herbs.

Hanging gardens

Hanging gardens are an excellent option for small spaces. You can use hanging pots, recycled containers, or even fabric pouches attached to a frame or railing. These hanging containers can be filled with a lightweight growing medium and used for cultivating herbs, lettuce, and other compact crops. Hanging gardens utilise vertical space effectively and are relatively low-cost to set up.

Hydroponic systems

Hydroponic systems, where plants are grown in water without soil, can be affordable if you opt for a simple DIY setup. You can create a basic raft system using foam boards floating on a nutrient solution. Alternatively, a wick system, where a wick draws nutrient solution from a reservoir to the plants, is inexpensive and easy to set up. These DIY hydroponic systems are suitable for growing various vegetables and herbs.

Shelve system

As the name suggests, shelves are used to create rows of vertical gardens. Similar to wall- or hanging gardens, containers with substrate is used keep the plants in. Pots or trays are stacked on the shelves in a tray of water, or is connected to driplines that provide the plants with water.

Planting a (vertical) garden and watching it grow

Some crops are not compatible with vertical systems – do not try to plant maize or pumpkins in this system. But there are still a multitude of other crops that can be used. Here are a few you can research:

  1. Herbs:

Herbs such as basil, cilantro, mint, thyme, and parsley are vital flavours that are in constant demand. They require relatively little space and grow well in vertical systems. Additionally, herbs are high-value crops because they have a quick turnover, allowing for multiple harvests throughout the year.

  1. Salad greens

Leafy greens like lettuce, spinach, arugula, and kale are popular choices for vertical farming. They are not only nutritious but also have a short growth cycle, making them ideal for continuous harvesting. Salad greens are versatile and are used in various culinary dishes, making them high in demand and a profitable choice for vertical farms.

  1. Microgreens

Microgreens are young edible plants harvested at an early stage. They are incredibly popular in high-end restaurants and farmer’s markets due to their intense flavour and high nutritional content. Microgreens can include varieties like radishes, mustard greens, and pea shoots. Despite their small size, microgreens are considered high-value crops because they can be sold at a premium price.

  1. Strawberries

Strawberries are a popular fruit that can be grown vertically in towers or hanging systems. They have a relatively high market price and are favoured by consumers for their sweetness and freshness. Vertical farming allows for efficient use of space, making it possible to grow a significant quantity of strawberries in a small area.

  1. Gourmet mushrooms

Gourmet mushrooms such as oyster mushrooms, shiitake, and maitake have gained popularity in culinary circles. They can be grown vertically in specially designed containers or shelves. Mushrooms have a relatively high market price, making them a profitable choice for vertical farms.

When choosing high-value crops for your vertical farming system, consider the local market demand, climate suitability, and your expertise in cultivating specific crops. Conduct market research and engage with local chefs, restaurants, and grocery stores to understand their requirements and preferences. By selecting the right combination of high-value crops, you can optimise your vertical farm’s profitability and contribute to the sustainable growth of your agricultural venture.

Shelves can also be used to create vertical gardens. (Source: Vecteezy)

For emerging farmers in sub-Saharan countries, vertical farming represents a pathway to overcome traditional agricultural challenges and create a more sustainable, efficient, and profitable farming enterprise. By harnessing the benefits of vertical farming, these farmers can contribute significantly to the local economy, local supply chain and food security.

Content: Africa Has Its First Chief Heat Officer. Five Things Should Be On Her Agenda

24 February 2023
analysis

Freetown's heat officer can set an example to Africa and the world as temperatures and risks rise.

Eugenia Kargbo has an unusual job: she is the city of Freetown's chief heat officer. Her role in Sierra Leone's capital is the first of its kind in Africa. She has been tasked with raising public awareness about extreme heat, improving responses to heat waves, and collecting, analysing and visualising heat impact data for the city, which is home to 1.2 million people.

Freetown is increasingly threatened by dangerous temperatures. In 2017, the Intergovernmental Panel on Climate Change ranked Sierra Leone third, after Bangladesh and Guinea Bissau, on its list of countries most vulnerable to climate change.

The risks are concentrated in its capital and largest city, Freetown, where some 35% of the population live in 74 informal settlements like Kroo Bay, often in disaster-prone areas like the seafront or hillsides. Houses are densely built and typically temporary structures made of "heat trapping" materials. Services that supports cooling, such as water and electricity, are usually inadequate.

As an architect whose work includes researching ways to reduce heat in African cities, I think the creation of an Heat Officer position is a good move. The world's cities are almost all getting hotter and, as the Intergovernmental Panel on Climate Change has warned, temperatures will only keep rising.

But, while this is a global challenge, African cities are unique. The significant proportion of urban dwellers who are poor and those whose living conditions do not provide adequate shelter from the elements make the African context unique and deserving special attention.

With these realities in mind, here are five things I'd suggest should be on the agenda of both Kargbo and any other heat officer appointed elsewhere on the continent in future.

1. Take a diverse approach to urban greening

Nature-based approaches are a great way to address increasing temperatures linked to climate change. Scholars have established positive links between green infrastructure, temperature moderation and even health outcomes in African cities as well as elsewhere in the world.

This has informed a growing number of tree-planting initiatives and the development of urban parks. But it is important that municipalities move beyond only these kinds of spaces. African cities are becoming densely populated; that means less space will be available for greening initiatives on land.

Vertical systems of building (for example on walls, roofs, columns) and urban infrastructure (for example on bridges, road furniture) should be explored to make up for the lack of space on the ground.

In the last few years, I have led the design and development of experimental vertical gardens in low-income areas of Nigeria and Tanzania. We have shown that these vertical gardens reduce wall temperature of residential buildings by as much as 5°C in Dar es Salaam. The gardens have other benefits like providing fresh vegetables for household consumption. Similar ways of growing vegetation vertically have been seen elsewhere in the world, including in Mexico City.

2. Strengthen the link between heat and health

Exposure to extreme heat usually comes with health problems - and can even kill people, as I and many other scholars have documented. It exacerbates underlying health conditions.

One area of concern when it comes to the heat-health nexus in African countries is that mosquito numbers increase in higher temperatures. This means malaria and other diseases transmitted by mosquitoes might become significant problems for Freetown and other African cities.

These health problems are further complicated by the fact that many city dwellers across the continent can't access adequate and affordable health care. Community health initiatives within cities and efforts to ramp up health services in qualitative and quantitative terms must be integral to heat adaptation plans and actions.

3. Focus on early warning and improved awareness

It is far better to be proactive than reactive. Heat vulnerability patterns within Freetown and other African cities must be studied and used to make sense of weather predictions in order to inform warning systems.

In the warning systems, for example, an alert level can be triggered when the weather forecast shows three or more consecutive days with daytime maximum temperature and humidity above a threshold of, say, 30°C. Other levels of alerts can correspond with higher temperatures. This sort of system has been implemented in Toronto, Canada, with good outcomes. A recent study of urban areas in Ontario (the province where Toronto is located) shows that early warnings may have meant fewer heat-related illnesses severe enough to warrant hospital or clinic visits.

4. Encourage the transfer of knowledge

Cities can adapt to heat faster when they share knowledge and experiences. Some scholars argue that inter-city collaboration and knowledge-sharing can enhance municipalities' resilience and improve urban residents' skills to deal with heat-related issues.

Kargbo's work will generate many lessons that can be shared with other African cities; she, too, will learn from other cities' successes and failures.

5. Let locals lead

While there is plenty to learn from more developed countries outside Africa, it is important to also draw from local indigenous knowledge and practices. An examination of knowledge and awareness about climate-related and environmental problems in African traditional society shows there is much to be learned from indigenous systems.

Top-down approaches are not enough. They must be complemented by bottom-up approaches in the planning, funding, execution and assessment of heat adaptation initiatives.

Inclusion is also important because it shifts power to those who are most affected by heat - people living in low-income and informal areas are disproportionately affected. Involving them enhances the impacts of initiatives and interventions.

The school received an environmental subsidy of NT $220,000 two years ago to plant large Dumbo flowers to form a green wall, which helps to cool down the temperature and purify the air, and also to install an automatic sprinkler system to maintain the ecology of the green wall.
According to the Environmental Protection Bureau of Chiayi City Government, since 2019, the Environmental Protection Department has promoted the vertical air green wall project. Since 2019, three schools, including Xingjia, Jiabei Elementary School and Jiabei Elementary School, have installed climbing plants on the school's daughter wall and the balcony of the classroom.
The Environmental Protection Bureau of the Chiayi Municipal Government said that this year, the Environmental Protection Agency expanded the target of subsidies, in addition to the original subsidies of public middle school, public elementary school, public preschool institutions, public welfare groups, public facilities, environmental protection night market, civic activity center and other venues, air green wall subsidies of 3,000 to 6,000 yuan per square meter, single subsidy ceiling of 400,000 yuan.
According to the Municipal Environmental Protection Agency, according to the results of the study, vertical green walls can reduce the concentration of nitrogen dioxide (NO2), suspended particulates (PM10) by about 40% and 60%, but also reduce the concentration of indoor fine suspended particulates (PM2.5) by about 10%, ozone by about 30%, and indoor temperature reduction by about 1.8 ℃.
According to the city's Environmental Protection Bureau, the appropriate plant types are lily bamboo, firecracker red, Yunnan yellow carnation, turtle, Boston kidney fern, hydrangea, African pansy or panthera, and can be selected according to the space planning and installation requirements, so that the space is more beautiful.

Content: In order to improve the environmental air quality and let children learn with peace of mind, the Taichung Municipal Environmental Protection Bureau has continued to build a clean air green wall in the school. This year, 12 schools in Jianping Elementary School, Juren Elementary School and Chongde Elementary School have received subsidies from the Environmental Protection Department.
According to the Environmental Protection Bureau, through the installation of clean air green walls, indoor air quality can be improved. At present, space such as classroom corridors and flower stands outside the daughter wall in Taichung City can be planted, which can achieve the benefits of dust retention, air pollution absorption and temperature regulation.
In order to strengthen the protection of the school environment for children, the Taichung City Environmental Protection Bureau expanded the subsidy for the construction of a clean air green wall on the campus, and the current subsidy amount to 1.76 million yuan, with an area of 358 square meters.
The Environmental Protection Bureau stressed that currently selected plants that can purify the air and do not need to spend too much money and time to maintain include the Dragon Tubeh, the Junzi and Wu Bamboo, the Turtle, the Cannonflower or the Honeysuckle.
How good is the effect of clean air green wall?
According to international research, vertical clean air green walls can reduce the concentration of nitrogen dioxide (NO2) and particulate matter (PM10) by about 40% and 60%. In addition, green walls can also reduce the concentration of fine particulate matter (PM2.5) in classrooms by about 10% and the concentration of ozone (O3) by about 30%.
Green wall is the most natural and energy efficient air purification facilities, no need to plug in electricity, self-circulation, to achieve the purpose of air purification, can be called the "most environmentally friendly air purifier".
Chen Hongyi, director of the Environmental Protection Bureau, said that in addition to blocking outdoor pollutants and improving indoor air, the air green wall can also adjust the temperature and drive energy conservation and carbon reduction. Next year, Taichung City is expected to expand the subsidy target, including community activity centers, public kindergartens and environmental night markets.

Recycling of Microalgae Water for Feed to Create a Circular Economy
[Ming Pao News] Microalgae microorganisms occupy small space, grow fast, photosynthesis is strong, and have a certain nutritional value, and in the increasingly high demand for environmental protection, in recent years more and more attention.
Some local enterprises began installing “microalgae reactors ” for the government and enterprises a few years ago, initially to improve indoor air quality, as well as as carbon reduction projects and green decoration, and later developed into the supply of microalgae powder to local lobster farms to add to the feed.
Ming Pao reporter Xue Wai Kit
Photographer Yang Po-hsien
Greentins Horticulture founder Tian Cheng-hui said that the company was founded in 2005, originally to represent foreign waste wood and plastic made of "green wood". In 2011, the company began to install a "soilless green wall" for enterprises to grow plants indoors, on the one hand, can green the indoor; on the other hand, can absorb carbon dioxide. I) Collaborate on the development of "Microalgae Reactor".
Simply put, this is a container filled with water to cultivate microalgae, but in order to enhance the photosynthesis of microalgae and maximize their ability to absorb carbon dioxide and release oxygen, the microalgae reactor is also equipped with adjustable LED lights, and constantly pump indoor air through the air pump to let the air pass through the water for cultivating microalgae.
Microalgae reactors in offices help reduce carbon
Optimized with 50 liters of microalgae water, the microalgae reactor can remove up to 5,500 kg of carbon dioxide per year; 1 cubic meter of microalgae water is more efficient than 100 square meters of forest.
Therefore, if you need to offset the amount of carbon dioxide emissions, installing microalgae reactors in the office is much easier and simpler than traditional tree planting.
In addition, it can also improve the air quality in the office and help improve the efficiency of employees.
Because many studies have pointed out that the carbon dioxide concentration in the air in a good office environment should be between 400 and 800 ppm; if the carbon dioxide concentration is between 800 and 1200 ppm, employees feel bored and tired.
Reduced CO2 levels increase employee productivity
However, when the microalgae reactor was launched in early 2019, the response of enterprises was lukewarm.
On the one hand, some companies do not know much about microalgae; other companies feel that the cylindrical pipe appearance of microalgae reactors is difficult to cooperate with indoor decoration.
Fortunately, the company attracted the attention of the FEHD when it participated in a seminar and exhibited microalgae reactors in the Science Park.
Subsequently, the FEHD installed microalgae reactors in two public toilets, followed by the Electrical and Mechanical Services Department's Kowloon Bay Headquarters.
In addition to the increasing pressure on large enterprises to publish the ESG (Environmental Protection, Social Responsibility, Corporate Governance) report, the company also provides an additional option to combine microalgae reactors and soilless green walls to beautify their appearance, and finally attract corporate inquiries and procurement.
In September last year, the company ’ s microalgae reactor was recognized as a “negative carbon emission ” environmental protection device by the Certification Center of the Chinese Manufacturers ’ Association of Hong Kong, meaning that it removes far more carbon dioxide than it emits.
According to their experience, the carbon dioxide concentration in the indoor air in local offices is usually over 1000ppm, which is a high level.
In general, the company recommends to customers that the number of microalgae reactors purchased should be sufficient to control the CO2 concentration within 800 ppm.
As of June, the company ’ s microalgae reactors have been installed in more than 20 indoor venues in Hong Kong. For the time being, government departments are still the sector with the largest number of purchases.
However, the construction industry has also had a lot of enquiries recently, and it is likely to overtake the government departments in the future.
Some construction companies have expressed their intention to hire multiple sets of microalgae reactors to be placed on the site during the construction period in the future to offset some of the CO2 emissions.
The biggest recent breakthrough was the supply of microalgae powder to Chien Kuo Seafood, which was added to its synthetic lobster feed.
Tian Cheng-hui revealed that because the microalgae in the microalgae reactor will continue to multiply, the number of microalgae will increase rapidly, causing the microalgae water to gradually become dark.
Therefore, the company will regularly go to the door to recover the old microalgae water, and replace it with new water and microalgae for customers, about once a month.
As for the old microalgae water, it will filter the water, and then squeeze, dry, sterilize, and crush to become a dry microalgae powder.
In the past, the company mainly added microalgae powder back to a small amount of water to make a liquid fertilizer for soilless green walls.
Chien Kwok Seafood ’ s founder Lin Pi-hsia said that the company has a seawater fish and lobster farm in the Yung Shu Au fish and shrimp farm in Sai Kung, covering an area of tens of thousands of square feet, which is one of the very few seawater fish farms and lobster farms certified by the World Wide Fund for Nature (WWF). It is currently the only breeding ground for lobsters.
She pointed out that lobster protein content is much higher than sea fish, so its nutritional needs are also diversified. They are usually given different feeds daily, such as small fish, green mouth, shell, oysters, etc.
The company last year designed a synthetic lobster feed that was fed every four to five days as a nutritional supplement.
Microalgae contain protein at affordable prices
When they heard Tian Cheng-hui ’ s proposal, they also felt that there was some reason, because microalgae contains certain protein and microalgae oil, and microalgae powder is affordable, which is also in line with the concept of low carbon, environmental protection and circular economy.
Therefore, the company began to include microalgae powder as one of the ingredients in its synthetic lobster feed design earlier this year, which also helps to reduce the overall cost.
In the future, the company intends to gradually test the inclusion of microalgae powder in some marine fish feed, especially when some fish eat high-priced feed imported from Taiwan. If the use of microalgae powder can reduce the amount of imported feed, it will help to improve cost-effectiveness and reduce carbon emissions.

Hobby or small-holder farmers: Vertical farming may be the way to go

By 7 min read

aquaculture-5990470_1280

Stackable planters can be purchased from local hardware or nursery suppliers to create your own vertical farm.

The need to optimise farming and improve yields on small plots of land is increasingly important. Due to challenges of water scarcity, limited arable land and high inputs costs, innovative solutions such as vertical farming can help to overcome these struggles.

Vertical farming is an approach whereby farmers cultivate certain crops vertically in stacked layers, in order to maximise space and increase yields. This is usually achieved by planting these crops in containers, structures, or stackable pots.

Most often, these structures incorporate aquaponics, hydroponics or aeroponic techniques. All of these are methods used in controlled environments, with various factors such as the water flow, lighting control, temperature, and substrate controlled by the farmer, unlike traditional farming practices.

Vertical farming has many benefits

The most obvious benefit of vertical farming is maximised land use. This method allows farmers to grow more crops in a smaller footprint, making it ideal for areas with limited land availability. But there are other benefits too:

Production throughout the year: Since the environment of vertical farms are more controlled, it is possible to cultivate a crop more than once a year, or to ensure that you have a consistent yield throughout the year – depending on the crop type of course. Any seasonal constraints are removed and production is more efficient.

Water conservation: Less water is used in these systems.with only the precise amount of water needed to provide the plants with sustenance. Where farms are located in greenhouses or indoors, less evaporation also occurs.

Low environmental impact: When less space is needed to grow more food, there is a lower impact on the environment. Less natural vegetation needs to be cleared to accommodate soil based farming.

Improved control over growing conditions: When coupled with greenhouse systems, factors such as light intensity, temperature and humidity can be regulated. However, the plants are more dependent on the farmer to provide nutrients as there is little to no soil used as a substrate. Farmers can exercise strict control over when which fertilisers are used.

How to start a vertical farm

If you are looking to start a vertical farm, you need to first allocate space. You will need a space to put up the vertical structures where it has ample natural light, and where the structures can be safe from animals. People often want to put vertical gardens in warehouses and storerooms, but it is very costly to provide enough artificial lighting to try and make up for the lack of sunlight.

If you plan on adding ventilation to a greenhouse, temperature control systems or any other high tech additions, remember to consider access to electricity or solar power. If solar is your choice, take note the for every hectare of artificial lighting you may need up to five hectares of solar panels to provide enough electricity.

There also needs to be a space where you can add drainage so access water can drain from your vertical farm.

Next, you will need to look at the crops you would like to grow as this will determine  your growing method.

Structures for vertical farming:

Vertical wall gardens

Vertical wall gardens are one of the simplest and most cost-effective ways to start vertical farming in cities where you have walls, and limited horisontal space. You can use recycled materials such as old pallets, wooden crates, or plastic bottles as planting containers. These containers can be attached to a vertical frame or wall, creating a vertical garden. This method is excellent for growing herbs, small vegetables, and even certain fruits like strawberries.

Tower gardens

Tower gardens are vertical systems that allow plants to grow in stacked layers. PVC pipes can be used to create vertical planting towers. Plants are placed in holes drilled into the pipes, and a water and nutrient solution is circulated through the system. PVC pipes are relatively inexpensive and can be found at local hardware stores. Tower gardens are suitable for growing a variety of leafy greens and herbs.

Hanging gardens

Hanging gardens are an excellent option for small spaces. You can use hanging pots, recycled containers, or even fabric pouches attached to a frame or railing. These hanging containers can be filled with a lightweight growing medium and used for cultivating herbs, lettuce, and other compact crops. Hanging gardens utilise vertical space effectively and are relatively low-cost to set up.

Hydroponic systems

Hydroponic systems, where plants are grown in water without soil, can be affordable if you opt for a simple DIY setup. You can create a basic raft system using foam boards floating on a nutrient solution. Alternatively, a wick system, where a wick draws nutrient solution from a reservoir to the plants, is inexpensive and easy to set up. These DIY hydroponic systems are suitable for growing various vegetables and herbs.

Shelve system

As the name suggests, shelves are used to create rows of vertical gardens. Similar to wall- or hanging gardens, containers with substrate is used keep the plants in. Pots or trays are stacked on the shelves in a tray of water, or is connected to driplines that provide the plants with water.

Planting a (vertical) garden and watching it grow

Some crops are not compatible with vertical systems – do not try to plant maize or pumpkins in this system. But there are still a multitude of other crops that can be used. Here are a few you can research:

  1. Herbs:

Herbs such as basil, cilantro, mint, thyme, and parsley are vital flavours that are in constant demand. They require relatively little space and grow well in vertical systems. Additionally, herbs are high-value crops because they have a quick turnover, allowing for multiple harvests throughout the year.

  1. Salad greens

Leafy greens like lettuce, spinach, arugula, and kale are popular choices for vertical farming. They are not only nutritious but also have a short growth cycle, making them ideal for continuous harvesting. Salad greens are versatile and are used in various culinary dishes, making them high in demand and a profitable choice for vertical farms.

  1. Microgreens

Microgreens are young edible plants harvested at an early stage. They are incredibly popular in high-end restaurants and farmer’s markets due to their intense flavour and high nutritional content. Microgreens can include varieties like radishes, mustard greens, and pea shoots. Despite their small size, microgreens are considered high-value crops because they can be sold at a premium price.

  1. Strawberries

Strawberries are a popular fruit that can be grown vertically in towers or hanging systems. They have a relatively high market price and are favoured by consumers for their sweetness and freshness. Vertical farming allows for efficient use of space, making it possible to grow a significant quantity of strawberries in a small area.

  1. Gourmet mushrooms

Gourmet mushrooms such as oyster mushrooms, shiitake, and maitake have gained popularity in culinary circles. They can be grown vertically in specially designed containers or shelves. Mushrooms have a relatively high market price, making them a profitable choice for vertical farms.

When choosing high-value crops for your vertical farming system, consider the local market demand, climate suitability, and your expertise in cultivating specific crops. Conduct market research and engage with local chefs, restaurants, and grocery stores to understand their requirements and preferences. By selecting the right combination of high-value crops, you can optimise your vertical farm’s profitability and contribute to the sustainable growth of your agricultural venture.

Shelves can also be used to create vertical gardens. (Source: Vecteezy)

For emerging farmers in sub-Saharan countries, vertical farming represents a pathway to overcome traditional agricultural challenges and create a more sustainable, efficient, and profitable farming enterprise. By harnessing the benefits of vertical farming, these farmers can contribute significantly to the local economy, local supply chain and food security.

Content: Africa Has Its First Chief Heat Officer. Five Things Should Be On Her Agenda

24 February 2023
analysis

Freetown's heat officer can set an example to Africa and the world as temperatures and risks rise.

Eugenia Kargbo has an unusual job: she is the city of Freetown's chief heat officer. Her role in Sierra Leone's capital is the first of its kind in Africa. She has been tasked with raising public awareness about extreme heat, improving responses to heat waves, and collecting, analysing and visualising heat impact data for the city, which is home to 1.2 million people.

Freetown is increasingly threatened by dangerous temperatures. In 2017, the Intergovernmental Panel on Climate Change ranked Sierra Leone third, after Bangladesh and Guinea Bissau, on its list of countries most vulnerable to climate change.

The risks are concentrated in its capital and largest city, Freetown, where some 35% of the population live in 74 informal settlements like Kroo Bay, often in disaster-prone areas like the seafront or hillsides. Houses are densely built and typically temporary structures made of "heat trapping" materials. Services that supports cooling, such as water and electricity, are usually inadequate.

As an architect whose work includes researching ways to reduce heat in African cities, I think the creation of an Heat Officer position is a good move. The world's cities are almost all getting hotter and, as the Intergovernmental Panel on Climate Change has warned, temperatures will only keep rising.

But, while this is a global challenge, African cities are unique. The significant proportion of urban dwellers who are poor and those whose living conditions do not provide adequate shelter from the elements make the African context unique and deserving special attention.

With these realities in mind, here are five things I'd suggest should be on the agenda of both Kargbo and any other heat officer appointed elsewhere on the continent in future.

1. Take a diverse approach to urban greening

Nature-based approaches are a great way to address increasing temperatures linked to climate change. Scholars have established positive links between green infrastructure, temperature moderation and even health outcomes in African cities as well as elsewhere in the world.

This has informed a growing number of tree-planting initiatives and the development of urban parks. But it is important that municipalities move beyond only these kinds of spaces. African cities are becoming densely populated; that means less space will be available for greening initiatives on land.

Vertical systems of building (for example on walls, roofs, columns) and urban infrastructure (for example on bridges, road furniture) should be explored to make up for the lack of space on the ground.

In the last few years, I have led the design and development of experimental vertical gardens in low-income areas of Nigeria and Tanzania. We have shown that these vertical gardens reduce wall temperature of residential buildings by as much as 5°C in Dar es Salaam. The gardens have other benefits like providing fresh vegetables for household consumption. Similar ways of growing vegetation vertically have been seen elsewhere in the world, including in Mexico City.

2. Strengthen the link between heat and health

Exposure to extreme heat usually comes with health problems - and can even kill people, as I and many other scholars have documented. It exacerbates underlying health conditions.

One area of concern when it comes to the heat-health nexus in African countries is that mosquito numbers increase in higher temperatures. This means malaria and other diseases transmitted by mosquitoes might become significant problems for Freetown and other African cities.

These health problems are further complicated by the fact that many city dwellers across the continent can't access adequate and affordable health care. Community health initiatives within cities and efforts to ramp up health services in qualitative and quantitative terms must be integral to heat adaptation plans and actions.

3. Focus on early warning and improved awareness

It is far better to be proactive than reactive. Heat vulnerability patterns within Freetown and other African cities must be studied and used to make sense of weather predictions in order to inform warning systems.

In the warning systems, for example, an alert level can be triggered when the weather forecast shows three or more consecutive days with daytime maximum temperature and humidity above a threshold of, say, 30°C. Other levels of alerts can correspond with higher temperatures. This sort of system has been implemented in Toronto, Canada, with good outcomes. A recent study of urban areas in Ontario (the province where Toronto is located) shows that early warnings may have meant fewer heat-related illnesses severe enough to warrant hospital or clinic visits.

4. Encourage the transfer of knowledge

Cities can adapt to heat faster when they share knowledge and experiences. Some scholars argue that inter-city collaboration and knowledge-sharing can enhance municipalities' resilience and improve urban residents' skills to deal with heat-related issues.

Kargbo's work will generate many lessons that can be shared with other African cities; she, too, will learn from other cities' successes and failures.

5. Let locals lead

While there is plenty to learn from more developed countries outside Africa, it is important to also draw from local indigenous knowledge and practices. An examination of knowledge and awareness about climate-related and environmental problems in African traditional society shows there is much to be learned from indigenous systems.

Top-down approaches are not enough. They must be complemented by bottom-up approaches in the planning, funding, execution and assessment of heat adaptation initiatives.

Inclusion is also important because it shifts power to those who are most affected by heat - people living in low-income and informal areas are disproportionately affected. Involving them enhances the impacts of initiatives and interventions.
