Implementation activities
The first phase of Mue Yen Mueng Yen consists of 3 main activities:
1. Mue Yen Mueng Yen - Tree planting Challenge in Chiangmai
This activity started off in a small group by using social media to help encourage people to plant a tree on their own land as well as to take care of them. As one person plants a tree, they post a picture of their tree with the hashtag #มือเย็นเมืองเย็น, then challenge 3 other friends to plant a tree. The first group of people who started this challenge also set a condition that if at the end of the year, any of their trees die, the owner needs to jump into the old moat in Chiangmai city. This is to make sure that those new trees have been taken care of and will survive in a long run. (Ref. 1,3,4)
2. Mue Yen Mueng Yen - Free saplings
As the tree-planting challenge started to spread among the people, the Mue Yen Mueng Yen group wanted to scale up their tree-planting in more public areas as well. They worked with Huai Hong Khrai Royal Development Study Centre Chiangmai in preparing 5,000 saplings with over 83 native species. They distributed these tree saplings to anyone who was interested in planting for free. This activity aimed to expand the green areas and tree planting from private properties to public spaces. All 5,000 saplings had been planted in Chiangmai in less than a year.
In this phase, the Mue Yen Mueng Yen group became bigger with the involvement of experts in planting. The Mue Yen Mueng Yen group also offers workshops and advice on how to plant tree saplings and maintenance techniques.
(Ref. 2,3,4)
3. Mue Yen Mueng Yen - Koo Muang Yen
After offering free tree saplings, the Mue Yen Mueng Yen group collaborated with Chiangmai municipality in establishing a tree-planting activity around the old moat of Chiangmai city. In total, 800 trees of native species had been planted around the old moat. They also invited all Chiangmai citizens to participate in planting these trees together. The municipality took care of the trees after this activity. At the same time, people who planted the trees were encouraged to come back to check on them and take care of the trees if needed. (Ref. 2,3,5)
The First phase of Mue Yen Mueng Yen was completed with 3 activities above. However, since then the Mue Yen Mueng Yen community has been working on other environmental projects, as well. For example, providing maintenance for trees that were planted during the first phase, planting new street trees in the city, work on canal ecology restoration, and offering rice growing and other environmental workshops.

5. Innovation
Type of innovation
Novelty level of the innovation
Please specify novelty level of the innovation
There are several tree planting challenges world wide, however, this challenge follows the popular idea on social media platforms called the 'ice bucket challenge' to involve more people in the programme. Thus, not the idea, nor the system is a novelty, however, the combination of these makes this project unique. (Ref. 1, 2)
Replicability/Transferability
Please specify Replicability/Transferability
While there were plans and commitments stating that if 5000 trees were planted in Chiang Mai - which was achieved - expanding to other provinces is on the horizon, no information was found whether this was realised or not. (Ref. 2)
