Mental health and wellbeing Issues

Importance of therapeutic landscape

It is impacting the globe. Some of the government restrictions to minimize the spread of diseases have been carried out. Movements of social distancing, physical isolation or even ‘lockdowns’ were implemented.

The impact of mental health and wellbeing has been negatively affected to many Australians.

Working from home and being isolated for a long period of time created tremendous stress.

Therapeutic landscape plays an important role to consolidate people’s emotions. It is believed that there

is a natural healing power while interacting with social and natural environment to relief physical and mental disorder.

What is specific regards with Covid-19?

The importance of access local blue and green space Is there sufficient public accessible water edge and parks ?

Currently, the whole Glebe Island is restricted with fences. It is not publicly accessible.

Site Qualities Topography and Hydrology

White Bay

Mapping out the topography surrounded the site Most area of the distributed ground is level to slope <3%. Majority of the site is relatively flat. It is a reclaimed area through times with human activities.

The higherst point around 40m, located at the Balmain side with steep slope. The slope gradient is around 25%-70%.

Mapping out the drainage surrounded the site

Rozelle Bay Key: Ridgeline Drainage

Modified creek with concrete Scale 1: 10000

Water capture zone for treatment

Surface run-off will run from higher point to lower point following the ridgeline.

It is also been found that there is a creekline is being modified by human. It is now a straight channel with concrete.

Site Qualities Topography and Hydrology

White Bay

Mapping out the soil surrounded the site

The disturbed terrain contained acid sulfate soil due to historical industrial background of the site.

The contaiminated soil can pose a risk to water quality such as heavy metals, into waterways and wetlands once rewetted, resulting in a reduction in pH and dissolved oxygen levels (Water Quality Australia).

Rozelle Bay Key: Hawkesbury (Coha) Birrong (ALbg) Disturbed Terrain(DTxx)

Scale 1: 10000

According to eSPADE, the acid sulfate soil in the site area is around 2 to 4m high, the bottom sediments in the surrounding bays are with high ASS probability.

Site Analysis Circulation- Public transportation

The newly built White Bay Metro Station will create new connection between Western Sydney, Inner West, the Bays and the City.

Balmain and Pyrmont are the closest ferry stops connecting the site.

One of the limits of the site currently is that the bus frequency is poor, waiting time is long due to insufficient bus lines. Situation would be improved by the new metro station opened.

The site will be more convenient and publicly accessible which will bring more people into the site through different modes of transport.

Key Light rail is supplementing the travel between Inner West and the City.

Closest access point Fences and Barriers

The site is all bounded around by fences along the northern edge and it is not publicly accessible.

There are often fences blocking the views on high elevated platforms such as at the sandstone cliff and Anzac Bridge side.

Constraints Toxic Soil and Poor Water Quality Soil Situation:

Due to the heavy industrial history of this site the condition of the soil has greatly deteriorated. Soil remediation is in needed.

This place is the heaviest contaminated area of the site.

Toxins included: • Polycyclic Aromatic Hydrocarbons (PAHs), present in fill materials.

• Heavy metals (arsenic, cadmium, chromium, copper, lead, nickel, mercury, and zinc) • Total Petroleum Hydrocarbons (TPH) • PCBs and VOCs • Asbestos.

Key: Total Petroleum Hydrocarbons (TPH) Benzo (a) Pyrene Heavy metals ( zinc, lead, cadnium etc)

Water quality Situation: Average dissolved oxygen saturation

Average total nitrogen concentration

Average total phosphorus

Average chlorophyll-a concentration

Average enterococci count

(Montoya, 2015)

The site has a poor water quality, all the parameters are higher than the ANZECC guidelines. The toxic soil that flows to the Sydney Harbour negatively affects the quality of water and hence affecting the marine ecosystem.

- This is a public art installation is using yarning to symbolise indigenous Australian arts and achievement to connect the community.

- It is also an interesting and playful art to interact with people around, enjoying relaxing moments appreciating the views of the Glebe Island.

- This is a terracing stepping of the edge to the water, allowing interaction with the harbour water with sensory engagement.

- Water has a calming and remediating effects on our souls to relief sad and stress.

Reconnect Stage 4: Human interactions with Nature Horticultural therapy through times Through community participation in horticulture and enjoy sensory stimulation through plantings.

- Plant species that are used to clean up, or remediate, contaminated sites via children educational programs.

- The soil is very toxic and contaminated at the moment with heavy metals, zinc and lead.

- Plant species and roots systems grown up while children also grown up through times. They are the witness and participate of the process of planting.

- Plant species and roots are fully grown up. It absorbed and purified the toxic and contaminated substances in the soil.

- While the through times, the child from the old days were grown up and can bring this to their next generation and educate them as well.

Revive Stage 5: Introducing new ecosystem -Hoverflies (Insect) What is Hoverflies?

Species that found in Australia

- insect family: Syrphidae 1 - beneficial insects appear in large numbers during the spring and hot summer.

- often seen hovering or nectaring at flowers - linger in gardens to feed at flowers and to seek shade

2

Life cycle of a hoverfly 3

Egg Eggs typically hatch a few days after they are laid.

Flight Pattern

Larva The role of larva is to feed. There are 3 stages of ‘instars’. The 3rd stage spent majority of year feeding with aphids.

Adult

Pupa The pupa is formed inside the skin of the 3rd stage. This stage take a few weeks to months to grow into adult.

Hovering in one spot

4

The function of adult is fully developed. It can mate, disperse and lay eggs for the next generations.

Hovering again

Biodiversity Hoverflies in Australia Where can we find hoverflies in Australia - Melangyna viridiceps, Simosyrphus grandicornis (Maquart), Eristalinus punctulatus(Maquart) and Eristalis tenax (Linnaeus) were present at low latitudes throughout the year but appeared at high latitudes (e.g. Victoria and Tasmania) during the summer.

- Fewer records in winter than summer

Why do we introduce more hoverfies into the Glebe Island - Are out and about today in Sydney inner west - Hard-working insect that pollen and pollinate flowers - Also feast on aphids, thrips, scale insects and caterpillars -Effective natural way to control pests in terms of reducing use of pesticide

Potential seasonal migrant in Australia

-All four species were recorded throughout the year with no gaps - A rapid, ubiquitous growth of hoverfly populations due to large numbers of cereal and canola aphids experienced in crops over winter and early spring.

Biodiversity Food chain illustraive diagram

Hoverfly larvae (Melangnya spp.) attack a range of soft-bodied insects and are a particularly voracious predator of aphids.

Hoverfly larvae go largely unnoticed as they crawl over foliage in search of their aphid prey.

There is no doubt that hoverflies, have held back damaging aphid populations in crops, and will continue to do so in urban gardens.

Overview Design Proposal Through model testing

Crime Prevention Through Environmental Design (CPTED) Model Testing- Night Time Safety At night time, lighting is essential to provide safety to people on site.

Warm and yellow light gives a cozy feeling and guide people through the dark.

Warmer lighting tends to be friend with insects and cause less pollutants and misleading signals to animals and creatures.

Crime Prevention Through Environmental Design (CPTED) Model Testing- Night Time Safety

The sitting structures with curve shape allows to form a safe and enclosed feeling to people. Abstract forms of shadows adds a light of play.

Edge lighting on the side of the steps allow people to walk closer to water safer.

Enjoy private night time with waves and sea breeze to quiet our minds.

Avoiding sharp corners with blind spots. Straight and flat road with the old railways track creates a way-finding symbol. Direct see-through way increase the sense of security.
