The exploration of survival mode of future climate refugees

Project Type: Individual Academic Work
Work Time: 12.2021-03.2022
Instructor: Hua Chengling
Site: Fongafale, Tuvalu
Massive floods, devastating wildfires, rising sea levels - and the countless lives and disrupted livelihoods they claim - are a reality that many countries are already facing.
And suppose the current rate of temperature increase is anything to go by. In that case, global sea levels will rise by 1.4 metres by 2100, forcing 10 per cent of the world's population to relocate, creating tens of thousands of climate refugees. Tuvalu, an island nation in the Pacific Ocean, is not only suffering from the effects of global climate change and sea level rise but also has underdeveloped primary, secondary and tertiary industries and has been repeatedly predicted by the World Meteorological Organisation to sink in fifty years.
The project aims to create a sustainable industry of coconut palm trees, fishing, rainwater harvesting and coral conservation through the local flora of Tuvalu, to alleviate their poverty to a certain extent, improve the living conditions of the people of Tuvalu and reduce the impact of climate change on the local people. The design is also an exploration of the future of climate refugee survival.

Effect of coconut chaff on nutrient contents in soil
Picking
Sourting
Coconuts still clinging to tall trees are harvested by human climbers. To remove the fruit from the seed, the coconut is impaled on a steel-tipped spike to split the husk.
The Use of Making Coconut Coir in Daily Life
Husking
Cleaning
Beating Workers beat the retted pulp with wooden mallets to separate the fibers from the pith Ripe coconuts are husked immediately and extracted coir.
They are buried in pits dug along riverbanks, immersed in tanks.
Retting Drying
Extracting
After soaking, coconut fibers need to be washed with water. The clean fibers are spread loosely on the ground to dry in the sun. Separation of the bristle fibers is accomplished in machines
The Flow Chart
Husking
Bristle fibers that will not immediately be further processed are rolled up.
Spinning
The yarn may be twisted into twine and bundled for shipment.
Knitting
After drying, the long fibers can be used as ropes and fishing nets.

Experimental design of interactive origami structure
Project Type: Individual Academic Work
Work Time: 10.2022-11.2022
Instructor: Hua Chengling
Site: Hangzhou, China
On the basis of umbrella structure, this project explores the shape changes of the structure in different quantities and combinations, and selects a stable structure with symmetrical beauty and abundant variability under the consideration of symmetry, diversity, stability and other factors.
At the same time, the project developed a custom feedback control system, which allows the structure to develop autonomously through infrared sensing. In terms of assembly, there is no need for glue, just replace the corresponding parts when damaged, and disassembly is very convenient.
This project expects to improve the feedback control system in the future to make the connection nodes more flexible and enhance the interaction with humans.

A computer simulation was set up to test the trajectory of the structure.Modeling was done using rhino, followed by simulated folding using kangaroo and crane in grasshopper. The figure on the right shows all the parts and the specific quantity of the structural model.
Interactive System Introduction
This diagram shows how the structure works as a whole, as well as a vision for the future of the project, which aims to make changes to the structure more flexible through software such as unity.
Test-bed Introduction
Interactive Display
The robotic control system includes infrared sensor for collecting human movements, computers and unity environments, and actuators to control fishing line.
