Short description of the intervention
The Chiangmai urban farm was developed on a former landfill site in the Chiangmai city centre area. The project was initiated by a local community architecture studio and supported by various groups of the local NGOs, civic groups and the local government. The project began in the middle of the COVID-19 pandemic, aiming to help vulnerable people in the communities nearby the site to increase food security, improve nutrition and build a self-sufficiency lifestyle. Moreover, the urban farm is designed to be a ‘public space’ that connects people from different backgrounds through agriculture. The Farm consists of various garden plots ideal for short-harvest and long-harvest species, a chicken coop, a plant nursery and a storage area. Knowledge sharing and capacity building are other goals of the project. Accordingly, training and workshops are organised in the bamboo pavilion of the garden. Since its establishment, the urban farm provides the local community with farming and learning opportunities and a space to socialize. The financial background of the project was provided through fundraising and the efforts of volunteers who developed this project into a self-sustaining farm without relying on donations.

Present stage of the intervention
Goals of the intervention
1. Transformation of a previously derelict area (waste dump) into a multi-functional urban farm used by the public.
2. Enabling vulnerable communities to produce their own food thus lowering their food expenses, improving nutrition and building self-sufficiency and food security.
3. Foster engagement and develop a sense of ownership of the urban farm among local communities while also supporting social interaction between people in the city.
4. Creation of an urban farm learning centre.
5. Creation of an urban farm that is able to operate on its own, meaning that it can run without relying on outside funding or donation.
6. Creation of a multi-functional open green area. (Ref. 1,2,4,5,6)

To achieve the goal of a self-sustaining farm, three more sub-goals were defined.
1. Generate income for nearby low-income community members and for homeless people in the area.
2. Generate income from the selling of farm’s products for the management and maintenance of the farm. This part requires farm manager to help.
3. Distribute farm products to volunteers or anyone who participated in the planting and taking care of the vegetables. (Ref. 4)
Quantitative targets
1. Produce 60,000 kg of food per year, which can feed around 300 households.
2. Create space that can accommodate 50 people per day (18,250 people/year). (Ref. 6)
Monitoring indicators defined
1. The amount of vegetables and other products that are being produced.
2. The number of people visiting per day (on regular basis and during special events).
3. The number of people who are strongly involved in the operation of the farm (regularly come to plant and harvest vegetables and take care of the chickens).
4. The number of households that benefited from the farm (consume and earn money from the farm's products). (Ref. 1,2,4,5)
Implementation activities
Land preparation stage:
1. Clearing of 5,700 tons of garbage.
2. Testing of the soil for contamination (e.g.: heavy metals and any other toxic substances). The result found contamination of several heavy metals.
3. Leveling of the site and bringing in new topsoil that consists of humus, biochar* and compost - approximately 50 cm. thick.
4. Building planting beds and filling them with a mixture of organic fertiliser and biochar - approximately 30cm. thick.
5. Construction of a well to extract underground water.
*Biochar is organic charcoal made by burning corncobs or rice straws. As the area is previously a dumping site for construction waste, the contamination of heavy metal can be expected. Biochar has been used to help improve soil quality by retaining soluble nutrients and remediating heavy metal pollution.
Land distribution for agricultural activities:
1. Creation of community gardens where short-lived vegetables (plants that need rotation/can be harvested in a short growing period) can be grown by low-income people in the nearby community. The vegetables from this area will be harvested and distributed to the community every week. If the products are more than needed, they can be sold but half of the earnings need to give back to the farm for internal management and buying new seeds and seedlings.
2. Creation of sharing gardens where long-lived vegetables or perennial plants are grown. Once they are grown, they can be harvested for a long period of time (such as lime, banana, mulberries, chilli, papaya). Vegetables in this area are grown by volunteers. Anyone can harvested in this area (for their own consumption) but under one condition which is they need to help watering and take care of the plants.
3. Creation of a chicken coop - Currently the farm has 100 chickens that can produce around 30-90 eggs per day. Eggs can be harvested by the farm’s management team for sell and people from nearby communities can also harvested for their own consumption and also for sell but half of the earnings need to give back to the farm.

Establishment of other facilities and activities:
1. Construction of a bamboo pavilion, as a multi-purpose area: a place for farmers-market, trainings, meetings and other activities and events.
2. Creation of a storage area
3. Organisation of events for people to come and work on the farm (growing plants, watering and take care of the plants, take care of the chickens).
4. Organisation of classes and workshops relating to farming.
5. Establishment of a coupon system - people who come to help watering and take care of the plants will receive a coupon that can be exchanged to any products in the farm.

The project was initiated by a group of local people who call themselves the ‘Promoter' (คณะผู้ก่อการ), led by the Jaibaan Studio (ใจบ้านสตูดิโอ), a local community architectural company. It also got support from various groups including Spark U Lanna group, Green Ranger Group, Mae Kha Canal community and the informal settlement community nearby, the Chiangmai Homeless network, the Ruk Chiangmai urban community network, the Community Organisations Development Institute, the Chiangmai Greenery Beauty Scented Group (เครือข่ายเชียงใหม่ เขียว สวย หอม), the Homesick Studio (ฮอมสุขสตูดิโอ), the Sai Tai Ork Rod group (กลุ่มสายใต้ออกรถ).
The Municipality and actors from the public sector also helped the project with financial and in-kind contributions. The Chiangmai municipality helped cover electricity and water bills for the project and provide certain machinery for clearing and levelling the land. The Marine Department offered soil for levelling the area. Several private companies and individuals donated biochar and seedlings. Finally, Chiangmai University also supported the project.

Please specify other landowner
The owner of the land is the Ministry of Interior while the Chiangmai municipality is responsible for the maintenance of it. Accordingly, the municipality does not have the power in determining the usage or give permission to other entities to use the land.
According to the law, any activity that occurs on this land needs to be approved by the Council of Ministers (the central government) which is a time consuming process. However, due to the pressure from the pandemic, the Governor of Chiangmai province gave preliminary permission to the 'Promoters' to use the land and establish the Chiangmai urban farm with an initial trial period of 1 year. If the project has positive outcome, the provincial and municipality authorities will issue this case to the council of ministers for official approval. (Ref. 1,2,3,4,6,8,10)

Type of innovation
Please specify system innovation
The project is a unique approach to urban area development and management that was born out of a need - connected to the COVID-19 pandemic. The project was initiated bottom up and in the end was able to create an ecosystem where representatives of the public, private and civic sectors came together for a joint cause: With the cooperation of civil society, the public sector, private sector and people in the community a food production focused project was implemented through the creation of a green space with opportunities for a better quality of life for people of marginalized communities along the Mae Kha Canal and the people of Chiang Mai who were hit the hardest by the pandemic (Ref. 6)
Novelty level of the innovation
Please specify novelty level of the innovation
While we have no knowledge of other grass-root urban farming projects in Thailand, the founders of the Chiangmai Urban Farm were inspired by The Network Urban Farmer group in Singapore. In the densely populated governmental housing areas, there was no opportunity for socializing. Thus, the Singapore government has a social engineering policy that combines diversity and determines the proportion of how many Muslims and Chinese people live in a building, so people with mixed religions feel connected. There is a common area below each building to inspire social interactions through various activities. One of them is the cultivation of agricultural land resulting in the formation of urban farmer groups. Each block grows different produce and exchanges them with each other.
In the case of the Chiangmai Urban Farm, instead of a private company, a local community-focused architectural studio took the lead and initiated the bottom-up urban farm project where the government and the people cooperate to manage an urban garden to support financially vulnerable communities while also creating an open space that brings together people from different backgrounds.

Impacts, benefits
Description of environmental benefits
- During the transformation of the wasteland, 5,700 tons of garbage were cleared. This has transformed a previous derelict dump site into an organic farm.
- The site was levelled with a metre of new topsoil consisting of humus, compost and biochar. Upon the topsoil, the planting beds were implemented with a mixture of organic fertilisers and biochar. The soil was tested prior to and after the intervention and the presence of heavy metal contamination was resolved and the quality of the soil improved. (Ref. 1,2)
- With the Chaing Mai urban farm, a 4800 m2 of wasteland was transformed into a green area with trees, shrubs and other edible vegetation. (Ref. 1,2)
Description of economic benefits
- The urban garden offers jobs for homeless people and volunteers to help take care of the plants and chickens. In exchange for their work and time, workers receive coupons that can be exchanged for products in the garden while also gaining experience and knowledge in farming. (Ref. 2)
- The garden also offers employment in farm management, which coordinates the activities.
- The project, so far, had helped in producing edible farm products for the locals to consume and had increased the agricultural production in the area. (Ref. 1,2)
Description of social and cultural benefits
- The urban farm enabled low-income communities of the Chiang Mai canal neighbourhood - who were most severely hit by the COVID-19 pandemic - to produce their own food and become self-sufficient while also improving their nutrition. (Ref. 1,2,6)
- The urban farm has encouraged the locals to get involved with agricultural practices and management. It is managed by locals with the support of the initiating architect studio. Moreover, the day-to-day management of the garden and the chicken coop is the volunteers, allotment owners and homeless workers' responsibility. ( Ref. 1,2,3,6)
- In the 'Community gardens' short-lived vegetables (plants that need rotation/can be harvested in a short growing period) can be grown. The vegetables from this area are harvested and distributed to the community every week. If the products are more than needed, they can be sold but half of the earnings - have to be given back to the farm for internal management and buying new seeds and seedlings. This practice has improved access to locally grown organic foods.
- In the 'Sharing gardens' long-lived vegetables or perennial plants are grown. Once they are grown, they can be harvested for a long period of time (such as lime, banana, mulberries, chilli and papaya). Vegetables in this area are grown by volunteers. Anyone can harvest in this area (for their own consumption) but under the condition that they contribute to the watering and tending of the plants. The vegetables have been tested against heavy metal contamination - that previously existed in the area - to guarantee the quality of the grown vegetables, thus making healthy food more available to involved locals (Ref. 1,2,3)
- In the urban farm workshops and events are organised on a regular basis about farming and agriculture. The farm also gives space for a farmers' market for local producers. These activities enhance participants' environmental and gardening knowledge while also enabling community building and providing space for social interactions. The designated bamboo pavilion gives space for such activities. (Ref. 1)
- Currently, the farm has 100 chickens that can produce around 30-90 eggs per day. Eggs can be harvested by the farm’s management team to sell and people from nearby communities can also harvest for their own consumption and also for sale but half of the earnings need to give back to the farm.

Expected qualitative social impacts:
- The production of 60,000 kg of food per year, which can feed around 300 households.
- Having 50 visitors in the garden per day. (Ref. 1, 2, 3, 5)

Comments and notes
Additional insights
Currently, the promoter (group of people who initiated this project) is establishing an organisation to take care of the project. The establishment of an official organisation will make it easier to process any legal actions (especially regarding the official approval to use this land as an urban farm from the central government) and receive help and funding from Chiangmai municipality which is good for the project in a long term.
