COMMUNITY PLAYGROUND The community playground included facilities like an indoor study room, playroom, picnic area, chest table, table tennis table, badminton court...

As Shei Kei Mei is lack of quality recreational area, the purpose of the playground is to provide an integrated playground that is suitable for all ages and it can become a local gathering place. Furthermore, the wooden platform is connected to the adjacent school which hopefully encourage the interaction between students in different schools.

SANCTUARY Ho Chung, Sai Kung, Hong Kong Agricultural Revitalization Society has an increasing interest in escaping urban life and going back to the natural living style. This project is going to cooperate with the nearby villager to revive the abandoned farmland in Ho Chung (Sai Kung). By reviving farmland and traditional farming culture, it can provide a refuge for both humans and wildlife. It provides habitat for wildlife, while supporting agriculture research and education activities.

Ho Chung is traditional farmland. People started farming here 4,000 years ago. The villagers grew rice and fished for subsistence. It has the largest potential farmland in Sai Kung which can be revived.

DESIGN ELEMENTS DESIGN PROGRAMME Different design strategies are proposed to achieve the project objective.

The farming area occurs in the north (wet farming) and south (dry farming).

In the north, rice will be planted together with companion planting and fish. While vegetable and fruit trees will be planted with covering crops and organic fertilizer. To provide a sustainable water source, a retention pond with a sluice to control the water intake and drain off is located in the middle to store water from rain and the nearby river for irrigation on the farm.

In the visitor center, an area is assigned as a nursery for research and practical farming purposes. Moreover, the compound includes a research office and farmer store that provide food and seats for visitors. Then, the cultural pavilion provides an exhibition area to show the nearby village’s culture with related photos and history content.

Human-elephant conflict (HEC) in Laos

Mitigating human-elephant conflict near the Laos-China border

The map displays area involved human-elephant conflict and its severity in Laos. 8% of total area where elephants occurred sustain crops damage by elephants. (Salter 1993) Currently, there is no formal government policies to systematically deal with HEC which can undermine the livelihood of those who frequently raided by elephants. (Johnson, 2004)

The Mekong River used to run parallel to elephant migratory paths. However, it is disappearing due to deforestation and urban development.

ELEPHANT CANTEEN

Lack of compensation Current government practice is to provide a small compensation payment to families of individuals killed by elephants, but crop damages are not compensated.

The project is aiming to mitigate the human-elephant conflict (HEC) in northern Laos by establishing a community elephant canteen (CEC) in Nam Ha Protected Area (NHPA). It is to experiment with the feasibility of different mitigation strategies such as repellent crops and elephant canteen.

Nam Xam Three elephants cause depredation in cultivated areas

Existing Problem

Ban Er lar mai Village

Lack of guideline There are no guidelines on how to systematically report and respond to conflict incidents.

Nam Ha A herd of up to 30-50 elephants often caused damage to crops in the area. These elephants most likely came from Mengla and enter the Laos border. (Johnson, 2004)

Nam Ha National Protected Area is a national protected area in Luang Namtha Province in northern Laos. This mostly forested park is home to a variety of ethnic groups and diverse animal and plant species.

With around 30-50 wild asian elephants, it is an important habitat for asian elephant.

However, it is facing threat such as hunting and slash-and-burn agriculture which damage wild habitats. (Johnson, 2003)

• Slash & burn practice leads to forest loss.

As a result, elephant attacks increase due to habitat and food loss

Population: 352 Average household size: 4.9 Household with electricity percentage: 94%

• Villagers lost income due to the restriction of logging and hunting which threaten elephants • Eco-tourism can provide income but is not sufficient to replace hunting & harvesting

Nam Ha Elephant Canteen

Objective & Aim • Mitigate human-elephant conflict

Lack of expertise The district officials lack the expertise to deal effectively with HEC, and there are no specially qualified elephant management specialists at a central level.

• Restore & provide a suitable environment for elephant • Reduce the villagers’ reliance on hunting and monocropping

Nam Phui Even with the largest wild elephant population, crop depredations (on paddy, bananas, and sugarcane) are rare. However, poaching is a serious problem as 8 elephants were killed between 2001 and 2002

Since the 1990s, rubber plantations expanded rapidly in northern Laos. A large area of forest in NHPA was burned down and replaced with rubber plantations. It reduces the habitat as well as food for Asian elephants. As a result, many elephants leave the forest and enter villages to find food which intensifies HEC in NHPA. Moreover, villagers are left entirely to their own devices when faced with conflict situations currently, since there are no formal government guidelines on how to systematically deal with conflict as well as no crop damage compensation in Laos. Therefore, the objective of the project is to mitigate human-elephant conflict and provide a suitable environment for elephants while improving villagers living quality.

Phou Khao Khouay Crop raiding occurred in the southern boundary of the protected area due to the construction of the Nam Leuk dam and reservoir which cause habitat loss in the protected area

Phou Hin Poun Elephants come down from the hills each year during the late dry season and return to the highlands in late June; agricultural damage is occasionally observed.

• Provide alternate income sources for villagers

Farmer dilemma At present villagers are left entirely to their own devices when faced with conflict situations.

• Create a system for sustainable farming

Strategy • Elephant canteen

Aggressive response Farmers guard their farms by using noise-making, fire, and lights to frighten elephants away when they appear. It may enrage elephants and cause death to either people or elephants.

• Repellent crop • Beehive fence • Early warning system

Do nothing Elephant raiding can consume the majority of the farmland which will ruin the farm’s income and livelihood.

Population: 1346 (The population of Ban Er lar mai Village + Ban Kouai na karng Village + Ban Phou yer Village: 482+512+352= 1346)

People in the NHPA scare elephants away using noise, fire, and lighting. Yelling, setting off firecrackers, smashing metal items, throwing stones, and using flaming torches or flashlights are examples of such responses. Elephants, on the other hand, soon learn to tolerate these sounds and lighting sources and return to raiding crops, according to research.

Ecotourism is another source of livelihood for the communities of Nam Ha NPA. Villagers are hired as tour guides or rangers for ecotours and other activities, which include forest trekking, kayaking, rafting, biking, river trips, and village homestays.

Ethnic: Khmu & Lao Loum Religion: Buddhism & Nature Spirit

Agriculture Activities Villagers main grow sorghum, Luang Prabang upland rice, sugarcane, and sesame, raising cows and buffalos. They also heavily depends on traditional slash-burn agriculture

Slash-and-burn

Bio-diversity

Hunting activities

The village in NHPA depends on traditional slash-burn agriculture to clear weeds & expand farmland which leads to soil degradation and reduces elephants’ habitat and food source. As a result, HEC intensified.

NHPA’s main purpose is to protect the habitat and biodiversity of the unique and amazing wildlife of northern Laos. There are rare wildlife species including Pangolin, clouded leopard, gaur, tiger, elephant

DESIGN PROGRAMME Repellent Crop Experiment

The Establishment of Elephant Canteen

Repellent crop experiment is to find out what kind of crop will not consume by elephants and its economic value. The research found out that the experimental crops did well while the traditional crops suffered severe damage from elephant raids. Furthermore, the income from experimental annual crops was initially low. However, with the combination of perennial crops, it can provide higher income than traditional crops while also reducing the risk of elephant raids.

Elephant canteen is a way to lure elephants away from farmer’s fields by planting elephant food crops near elephant’s habitat.

The efficacy of elephant food crops fades with time as elephants become picky and re-enter the village to eat crops like corn and sugarcane again.

The project is heavily dependent on the government since the government decides and funds all the development. The elephant canteen cannot be continued if the government stops funding.

There is 20 staff working in monitoring and early warning service. They monitor elephant movement through drones and infrared cameras. They inform villagers to take precautions when elephants get close to the village.

THE RUIN CHURCH Comfort Terrace Garden, Fortress Hill, Hong Kong Urban Intervention Comfort Terrace Rest Garden is a sitting-out area near the residential area (Comfort Terrace). It is located along the slope and the topography is dynamic with multiple stairs leading to the place. The MTR ventilation shaft and the aging material surface inside the park are the main features of the place. This project is to design a series of follies that match the character of the place while making it more interesting.

FOLLY INTERVENTION What is a Folly?

“An ornamental structure—oftentimes strange, fantastical, or whimsical—built for just one purpose: pleasure!” - Hadley Keller, 201 7, Architectural Digest “The Ruin Church“ is the theme of the folly design. It is inspired by the historical content of Fortress Hill as an important WWII British stronghold.

The folly is to imitate a church that got bombed to ruin during WWII. The ruined church gives a new identity to the place. The ruin is also practical such as forming shelter and sitting area.
