Nourishing Dhaka The design of an innovative, scalable, lowcost, carbon-positive community for climate change refugees.
Climate change
Refugees
Urban expansion
Low-cost shelter
Rising levels of atmospheric CO2 and other emitted greenhouse gases is causing anthropogenic global climate change. As a result, rising seas, and more severe and frequent storms have destroyed villages, forcing people into cities to nd work. Bangladesh houses the most climate refugees of any country, most often in Dhaka from the rural south. The world’s urban population experienced a 15-fold increase during the last century. Overcrowded megacities are growing faster than their infrastructure. Dhaka, the world’s fastest growing megacity, is home to 17 million people. Most Bangladeshis live on less than $2 a day. In Dhaka, a majority of the is especially high among migrants.
Living materials
Carbon sequestration
Concept
Jordan Solomonic Thesis 2015-16
Many natural materials may be grown from waste products at zero to minimal cost. Mushroom bricks and crops are examples of organic waste matter converted into useful products. Living materials, such as plants, bacteria, and algae, are able to pull greenhouse gases from the atmosphere during photosynthesis. Mycorrhizal fungi help convert this carbon into soil. We are inexorably part of the systems and cycles of nature. This project aims to highlight the common misconception that we are able to create a world that is distinctly human.
Dhaka, Bangladesh General information
Location
Dhaka is located in a river basin and is surrounded by eight rivers. Two-thirds ow zone. of the city Dhaka, the capital of Bangladesh, is located in the country’s geographic center. Dhaka’s most urgent ooding. New development is occurring in wetlands, exacerbating the problem.
Population
Dhaka is the world’s 8th largest and fastest-growing megacity. Its population is growing by 4% annually. Dhaka is home to 17 million people, up from 12 million in 2005, and 6 million in 1990. It is projected to have 20 million inhabitants by 2020. Bangladesh is growing at 1.22% annually, with the US at .75%.
Demographics
Nearly half of Dhaka’s population live in slums. Wages are lower than anywhere in the world. A large portion of the Dhaka’s population lack access to basic rights, making the city nearly uninhabitable. With a high reproductive rate and selective migration, 40% of the city is under 14.
History and Culture
Bangladesh gained independence from Pakistan in 1971. Most Bangladeshis are Bengali Muslims. Bangladesh has historic ties to the Indian subcontinent. 90% of the nation’s population is Muslim and 9% are Hindus. The average family size is 4.4 and cricket is the most popular sport.
Traditional Housing
Mud and bamboo, available in the Ganges delta, are the most common building materials in Bangladesh. Traditional mud houses are highly resistant to cyclones and tidal surges. Their thick walls and thatched roofs provide thermal comfort. However, the houses are susceptible to earthquake damage.

Carbon and Climate Change Adaptation and mitigation g
Global Carbon Cycle
Carbon is cycled through the planet through a variety of natural and manmade processes. Within this process, humans, through fossil fuel combustion and deforestation are moving carbon to the atmosphere. To the right, the storag of carbon is measured in Gigatons.
Climate Change
Carbon emissions are causing increased temperatures, sea level rise, and more severe and frequent storms. The rate of warming averaged over the past 50 years is nearly twice the rate for the past 100 years. Global surface temperature will increase by at least 2.0°C by the next century. (IPCC)
Carbon Sequestration
Biotic sequestration is a natural process and win-win scenario. Abiotic is man-made and not cost-effective. Biotic carbon sequestration enhances ecosystem and agricultural services. As a result, it is both economically and environmentally positive. This occurs through photosynthesis and soil building.
Terrestrial Carbon
This project will act as a carbon sink, using the natural process of biotic terrestrial carbon sequestration. Soil is the major carbon sink in the biosphere, holding nearly 3 times the carbon as crop biomass. Terrestrial carbon sequestration is the process of converting atmospheric carbon to soil.
Drawdown
Drawdown is the point at which greenhouse gases in the atmosphere begin to decline (drawdown.org). Drawdown is the overarching goal of sustainable practices. This project is looking to contribute to a global drawdown of atmospheric carbon pollution.
Climate Change in Dhaka Effects and strategies g
Climate
Dhaka experiences a hot, wet, and humid tropical climate. Most rainfall occurs during the monsoon season. Temperatures never drop below freezing and 80% of the city’s rain falls between May and September. The southwest monsoon occurs between tropical storm seasons, and tornadoes are very common.
Climate Change Effects
Winter Wind
Pre-monsoon
Monsoon
Post-monsoon
Climate change is triggering a migration the likes of which the world has never before seen. Although it emits less than 0.1% of global greenhouse gases, low-lying Bangladesh is one of the most vulnerable countries in the world to the effects of climate change.
Climate Refugees
With estimates between 15 and 30 million, Bangladesh has more climate refugees than any other country. Bangladeshi climate refugees often move to the slums of Dhaka in search of a new livelihood. As the massive migration continues, half of Dhaka’s population is expected to live in slums by 2050.
Rapid Urbanization
The city of Dhaka is seeing rampant oodplain development, increasing future risks. In 1970 a Category-3 tropical cyclone killed 500,000 Bangladeshis. With the onset of climate change, Dhaka is facing even greater risks due to more severe storms and high population density.
Urban Flooding
ooding is the primary climate risk facing the city and it occurs mostly during the monsoon season. According to the IPCC, Bangladesh will lose 17 percent of its land by 2050 and Director of NASA’s Goddard Institute, James Hanson, predicts the entire country could be under water by 2100.

Garment Industry
Informal Settlements
40 percent of Dhaka’s population lives in slums beside railway tracks, along riverbanks, and on swampy lowlands.
Slums of Dhaka Metropolitan Area
Slum dwellers often have sporadic access to stolen electricity, share hand-pumped water with as many as 200 people, use communal open toilet pits, and lack access to waste treatment.
Slum Populations
Three-quarters of the residents living in Dhaka’s slums were migrants, with recent migrants being poorest. Measured on a per capita basis, the largest number of migrants come from Barisal in the south. In this area of the low-lying Ganges delta, land is especially susceptible to sea-level rise.
Land Use
Dhaka is experiencing massive overcrowding and development has ood ow zones. occurred
Flood- ow Zones
Land Use over Time
Korail
The typical construction is one room of steel sheets held up with wooden poles. During the monsoon season, cholera and malaria are common as residents wade through muck and excrement.
Manufacturing development has occurred along waterways and roads for easy shipment of raw materials and nished products. This development is making the city more vulnerable to oods.
Pollution
Brick manufacturing is a major source of pollution. Associated annual health costs are estimated at $1million/kiln.
Brick Kiln Locations
Airborne Particulate
Housing
2,200-4,000 premature deaths and 0.2-0.5 million asthma attacks per year have been linked to brick manufacturing in Dhaka. With cleaner practices, health cost savings could be $1/4 billion by 2020.
Sweatshops and Exploitation
Bangladesh has the cheapest labor in the world. Minimum wage (garment) is $37/month, and was $20 in 2010. 82.8% of Bangladesh’s 150 million people live on an income averaging less than $2 a day. With doubledigit in ation, protest and clashes with police have become increasingly common.
Dhaka’s largest slum is home to roughly 70,000 people. Sanitation is absent and outbreaks are common.
The most common housing condition in Dhaka’s slums is an 85ft2 semipermanent, tin-roofed rental unit for 5. Most houses are considered semi pucca structures with brick walls. Temporary, weak kutcha structures were nearly as common. The average community has 8 families per tap and 4 families per latrine.

Refugees
I use the term refugee to refer to Internally Displaced Persons, the UNHCR uses person of concern.
Formal beliefs
Experts expect 250 million people to be forced to move by 2050. Of those, 20-30 million are expected to be in Bangladesh, likely the largest number from one place.
Refugee Population
The Manasara and Mayamata are important treatises which describe rules for building. The Vastu Purusha Mandala, the master grid for design, symbolizes the cosmic man on an ordered site.
Climate change refugees are moving into Dhaka d a new livelihood after the destruction of their land.
Traditional Architecture
Female migrants, seeking education and marriage, are often younger than males who move in search of work.
Religion
Women residing in slums were much more likely to be engaged in paid employment than their male counterparts and have a somewhat higher level of education. Many migrants earn less than $1 a day.
Work
On average, household income in slums is $45 a month, water and latrines are shared by 9 families. The majority of those who live in slums pull rickshaws or work as part-time domestics. Others, mostly women, work for apparel industries. Children often scavenge instead of going to school.
Bangladeshi Culture
Much of daily life in Bangladesh takes place under a veranda. People speak Bang . than men but these rules are relatively relaxed in cities. The harmonium, tabla, and sitar are common musical instruments.
Various vernacular architectures of Bangladesh use local materials and are adapted to the tropical climate. While there are distinct differences between the architectural styles of the tribes of Bangladesh, they employ the courtyard typology and use the grasses and mud widely available in the river delta.
The International Organization for Migration says about 70 percent of slum dwellers have come to Dhaka because of climate-change adversity. Dhaka is the primary city for receiving in-migrants.
Slum Population
Vastu Vidya is the ancient Indian science of architecture dating back 3500 years.
Islam is the predominant religion in Bangladesh. The nation’s monuments are stylistically tied to India. Historically, the country has been part of Buddhist and Muslim empires. As a result, much of the traditional architecture is Moorish in style.
Common Employment
Rickshaw driver
Use of space
In traditional Bangladesh, the veranda is the place where most of life occurs. Everyday cooking is done outdoors. Culturally, Bengalis are separated by gender, often at meals. However, this distinction is not as prevalent in the city. Also, when outdoor kitchens are enclosed, a new one is built for everyday use.
Apparel industry
Contemporary
Bangladesh has the lowest minimum wage of any country. Architecture is often made with u shed materials. Although uncorrupted institutions and women’s education are some long-term solutions to Bangladesh’s troubles, inexpensive, beautiful architecture can help provide some hope.

g material is shrink ooring material
Roof and Floor is soil cement.
Steel reinforcing is expensive and often critically underused in developing countries. Natural bers retain carbon and are strong in tension. This study found an optimal ax ber reinforcing length of 3”.
Edible Growth
Bricks are grown and fused using mycelium. Minor variations allow the bricks to integrate with a diagrid. Bricks walls are reinforced with vertical bamboo members. Bricks sequester carbon through the interaction of mycorrhizal fungi and plant roots in a layering material typology.
Calcium carbonate cement is carbon positive because its raw ingredients are water and pollution. This material is made using the process that marine organisms use to produce shells and reefs.
Low-cost Reinforcing
The primary frame is composed of bamboo lashed together in a loose diagrid with jute rope. This method is fuses traditional skills with locally available and rapidly renewable materials. Furthermore, through the integration of a courtyard typology, vernacular traditions are suggested.
This 3D printed brick holds water for passive cooling in hot and dry climates. It is inspired by the Muscatese evaporative cooling window, which combines a wood screen and a ceramic jug.
This project uses a new process to cultivate edible fungi that digests plastic as it grows. Oyster mushrooms, used in mycoremediation, are used to convert waste plastic and toxins into food.

The roof consists of a faceted bamboo frame sealed with translucent shrink wrap. The oor is made of bamboo matting, and covered in natural clay-based textile-reinforced soil cement.
Apertures
Windows and doors are framed with bamboo. Instead of glass, transparent shrink wrap is used. Bamboo is the framing material used for structure and apertures. Much of the material used can be grown in less than one year.
Mushrooms Biology gy and use
Life Cycle
The mushroom, the reproductive part of the fungus releases spores in a process known as sporulation. Spores land and produce mycelium underground. As the mycelium grow, they produce a small mushroom covered in a universal veil. The mushroom breaks through the veil as it grows.
Cultivation
Mushrooms may be cultivated indoors or outdoors. They feed by breaking down nutrients, some require light. After choosing a mushroom spawn and substrate, the next step is inoculation. Given the right environment, the growing medium will ll with mycelium until mushrooms are ready for harvest.
Mycoremediation
Fungi are biological gateway species for remediation, producing enzymes which convert oil into fungal sugars. Mushrooms, grown from hydrocarbons, sporulate and attract insects, whose larvae are eaten by birds, who bring in seeds, which sprout into plants. Our best antibiotics also come from fungi.
Fungal Carbon Sequestration
Fungi sequester carbon in the form of calcium oxalates and in soil when living symbiotically with an autotroph. Autotrophs are organisms which create their own food. The hyphae of mycorrhizal fungi form symbioses with plant roots, allowing both to grow much faster. Carbon in the hyphae remains in soil.
Symbionts
Lichens are fung lled with algae. Endophytic and mycorrhizal fungi associate with plant roots. Lichens are symbionts whose parts cannot survive alone. Algae capture carbon in photosynthesis. Arbuscular mycorrhizal fungi are found in 80% of plants and store carbon through soil aggregation.
