Introduction Definition of ‘Urban’ in the 21st Century What is ‘Urban’? According to the Cambridge Dictionary (2019a), it is an adjective to describe something “of or in a city or town”. Then what is a city or a town? Again, with the dictionary (2019b), “city” is a noun meaning a large town while “town” is another noun defined as: “a place where people live and work, containing many houses, shops, places of work, places of entertainment, etc., and usually larger than a village but smaller than a city” (Cambridge Dictionary, 2019c) So, if “urban” is an adjective to describe a city or town, would it be a negative word rather than a positive one comparing to the past in this 21st century? In the last century, “urban” area gave people an impression that the described area is more advanced, higher technological, smarter and wealthier places to live. Later it even led to the Rural-Urban migration in many different cities all over the world especially in China because of these attractive reasons. However, in the mid-19th century, people who lived in cities found more and more problems there, such as, overcrowding, health issue, energy and food supply, deleterious living environment and even the global issue: climate change in the late-19th century etc. Therefore, “urban” seems also expressing an area with these problems.

Then, people start to think about how they would improve the situation. Ian McHarg suggested “Design with Nature” (1969). By considering nature as a part of the development, people try to mitigate the existing urban problems. Later, different ideas with nature are developed, for example, ecological urbanism (Mostafavi and Doherty, 2016) and re-naturing the city (Lemes de Oliveira and Mell, 2019), and are tried to be implemented in various metropolis. Thus, some “natural” and “ecological” elements are also included in “urban” now. In the future, hopefully in the mid or late21st century, “urban” will evolve into the people living and working areas integrating with our great nature with an optimistic and sustainable way. In this report, an urban metropolis: The Greater Sydney, Australia with its “famous” problem of extreme heat, is studied as an example. The respective problem, causes and crises are investigated and analysed. Future government development plan would be studied and a new vision of the future landscape in Sydney would be proposed in order to form a better “Urban” living area.

The Greater Sydney, Australia The Greater Sydney, the largest city located in the southeast coast of Australia with a total land area of about 12,368.2 km2, is the capital of the state of New South Wales (NSW) according to the Australian Bureau of Statistics (ABS) (2019a). By the ABS, the boundary of the Greater Sydney, also known as the Greater Capital City Statistical Area, is from Wyong and Gosford in the north to the Royal National Park in the south following the coastline in between. Its west side is surrounded by the Blue Mountains, Wollondilly and Hawkesbury while the east side by the Tasman Sea (City of Sydney, 2018; ABS, 2019a). The estimated resident population of the area as at 30 Jun 2018 is 5,230,330 while the population density is 422.9 persons/ km2 (ABS, 2019a). There are up to 35 local councils with more than 650 suburbs linked by various transportation systems consisting of rails, buses, ferries, taxis, vehicular and cycle networks (City of Sydney, 2018).

The Boiling City – Current Situation Climate of the Greater Sydney The Greater Sydney has warm summers and cold winters (BOM, 2006) and therefore is classified as having a humid subtropical climate, a Cfa climate, based on the Köppen–Geiger climate classification (Kottek. et al., 2006). However, there are more hotter days in not only the Greater Sydney but also the entire Australia due to more severe heatwave caused by the global climate change and also the stronger urban heat island effect which exacerbates the situation (Department of Planning, Industry and Environment, 2019a).

Global Scale - Global Climate Change In the report State of the Climate 2018 by BOM and CSIRO (2018), it states that Australia’s weather and climate had keep changing to response global warming and warmed by just over 1 °C since 1910 (Fig. 2.2). The changing will probably raise the frequency of extreme heat events in the future (Fig. 2.3). “Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate. (high confidence)” was quoted from the special report “Global Warming of 1.5 ºC” (IPCC 2018, p4). This estimated global temperature changes seems to exceed the projection of maximum temperature in Sydney increasing by 0.7°C by 2030 and up to 1.9°C by 2070 by the NSW government in the future (Office of Environment & Heritage, 2015a).

Macro Scale - The Boiling Sydney

City Scale – Urban Heat Island Effect

Based on the Annual Climate Summary for Greater Sydney by BOM (2019a), the year of 2018 was a warm year in which the annual mean maximum temperature measured at Sydney Observatory Hill was within the top five warmest years on record. On 7 January, a summer day, four sites observed the highest temperature on record while Penrith even recorded 47.3°C which is the hottest day recorded in the area since 1939. The mean maximum temperatures raised typically by 0.5 to 1.5°C while the mean minimum temperatures mostly increased by less than 0.5°C above average across Sydney (BOM, 2019b)

Back to 2015, besides the main factor of global climate change, it was investigated by the NSW government that the urban heat island effect in the metropolitan area would further worsen the heat event situation (Office of Environment & Heritage, 2015a) (Fig. 2.4). The study shows that there is a strong relationship between the urban temperature and the change of land use during urbanization process in promoting the urban heat island effect, especially for the proposing development of the Western Sydney.

SUMMARY 2

The increase in the mean temperature and the number of extreme heat event days in the entire Australia as well as the Greater Sydney are not only caused by the global warming, but also the urban heat island effect in the metropolitan area.

What’s Wrong? Urban Heat Island Effect Urban Heat Island Effect The urban heat island (UHI) phenomenon refers to the higher level of ambient temperature in urban areas comparing to the surrounding suburban or rural areas (Fig. 3.1) because of: • • •

the loss of vegetation cover; the raise in the solar radiation absorption by the urban structure materials; and the changes of air mass movement through the urban fabrics (Santamouris et al., 2017; Mahdavi et al., 2016; Rajagopalan et al., 2014; Oke, 1982).

The Green • Lattice

Fig. 3.2 - Illustration on the causes of UHI effect (Deutscher Wetterdienst, 2019)

SUMMARY 3

The urban heat island effect is caused by the losses of green cover, raise in solar radiation absorptions and changes of air movement in the urban area leading to a higher ambient temperature.

The temperature varies in different extends with time and location in accordance to the specific meteorological, locational and urban characteristics of an area. (Kleerekoper et al., 2019; Santamouris, 2001; Oke, 1987) All the above three factors are highly

related to a process – URBANIZATION (Hsieh & Huang, 2016; Santamouris & Asimakopoulos, 2001), the change of land uses; i.e. forms and fabrics.

Why? URBANISATION! Population Growth Urbanisation – Population Growth In the Greater Sydney, there is an increase of resident population by 93,400 (1.8%) from 2017 and the estimated resident population of the area as at 30 Jun 2018 is 5,230,330 (ABS, 2019b). That leads to the Greater Sydney becoming one of the capital cities with the largest raise in the population (ABS, 2019c). The growing population is the main cause for rapid urbanization in the north-west and south-west area of the Greater Sydney in providing adequate housing and job opportunities for future development (Office of Environment & Heritage, 2015a).

Urbanization LAND USE CHANGE According to the impact assessment on the land-use change in the Greater Sydney’s future temperatures with respect to the NSW government development plan carried out by the Office of Environment & Heritage (Adams et al., 2015), different types of land use changes from the Bureau of Transport Statistics (2012) were analysed and divided into eight categories as shown while the temperature changes were simulated basing on the ECHAM5 GCM-driven RCM (R3) simulations from the NARCliM project (Evans et al. 2014).

The result shows that the temperature raise would be enhanced by the change of land uses (Fig. 4.1, 4.2 & 4.3). Overall, the annual average hourly temperature changes from –1.3 to +1.4°C while that daily temperature changes from –0.4 to +0.8°C. That means the maximum annual average temperature increase would be the double of that as predicted by 2030,

0.7°C (Office of Environment & Heritage, 2015a). The greatest annual increase in temperature of land use are projected in switching form forest or grasslands to urban area, from +0.2°C to +0.4°C (Fig. 4.4) especially in summer afternoons and during the night, and these changes are expected to occur exactly in the north-west and south-west development area.

SUMMARY 4

In the Greater Sydney, the change of land uses in urbanisation planned in the SW area, ascribable to the rapid population growth, is the main cause of the urban heat island effect and estimated to further worsen the extreme heat situation.

The findings also show that there is a decrease of temperature in the existing urban area in the coast at night which is potentially induced by the raising building height (i.e. more shading) and the presence of stronger coastal sea breezes due to larger temperature differences between the land and sea surface temperatures. However, for the inland area, the extend of the temperature increase is found to be much higher. This might be caused by less cooling effect from the sea breezes due to the increase distance from the coastal area; the blockage of urban structures in the coastal side as well as the creation of stagnation UHI region over the city Sydney (Santamouris et al., 2017; Office of Environment & Heritage, 2015a; Sakaida

et al., 2011; Ado, 1992). And this problem is unique and specific to the geological characteristics of the Greater Sydney. Therefore, temperature changes, i.e. the UHI effect, caused by land-use alterations are predicated to further exacerbate that by human induced climate change (Office of Environment & Heritage, 2015a). In order to relieve the problem, other than the shortterm method of changing building materials and increasing vegetation coverage to improve the micro-climate, long-term measures such as sustainable city planning or regeneration should be proposed and implemented to enhance the overall mesoor even marco-climate of the Greater Sydney (Santamouris et al., 2017; Office of Environment & Heritage, 2015a). The Green â&#x20AC;˘ Lattice

In order to support the raising cooling energy consumption of the buildings or indoor environment in the urban area, the peak electricity demand is increasing. Recent research by Santamouris et al. (2015) discovered that the demand for electricity changes ranging from 0.45% to 4.6% per degree of temperature increase due to the UHI effect. The cooling demand for buildings are studied to be increased up to 100% in various cities (Hassid et al., 2000). During summer, the consecutive three or more days of high temperature (above 35 Â°C) imposes great stress to the electricity supply system and causes blackouts and it may cause various accident in household, traffic and emergency services (Energy Networks Australia and Australian Energy Council, 2019).

Rise in Energy Demand

CRIS a Viciou Increase in Greenhouse Gases Emission and Pollution

The more the amount of electricity needed, the more amount of greenhouse gases are released. According to the data from the Department of the Environment and Energy (2019), fossil fuel is still the main fuel source to generate electricity in Australia, 81% of the total electricity production in 2018. The increase amount of anthropogenic carbon dioxide and other greenhouse gases by fossil fuel combustion would further contribute to the global warming and climate change (NASA, 2019).

On the other hand, in urban surface, the raise in temperature increases the stimulation of ozone formation. Ozone is one of the essential components for photochemical smog formation in the urban area under high temperature leading to deleterious air quality and road visibility (Sillman, 2003). Ozone would also be harmful to human health as it would lead to diseases related to heart or respiratory system (Kleerekoper et al., 2019; WHO,2004).

The Green â&#x20AC;˘ Lattice

The rise in urban temperature is found to be highly correlated with the human deaths by some studies (Baccini et al., 2008). Two major kinds of hyperthermia, meaning body produces or absorbs more heat than it dissipates (Kosaka et al. 2004), heat exhaustion and heat stroke, would cause multiple organ failure and mortality (Office of Environment & Heritage, 2015b). Elderlies, disabilities, people with chronic diseases, homeless people and those who live in poor quality environment are all highly vulnerable to heat stress (Office of Environment and Heritage, 2015b) And the government estimates that the annual average number of heat-related deaths in Sydney would increase from 176 from 2007 to 1050 in 2050 (Australia State of the Environment, 2016).

Health Risk and Mortality

SES us Cycle Deterioration of Living Environment In indoor environment, the temperature would be controlled by the heating, ventilation and air-conditioning (HVAC) system in order to keep the optimal room temperature (25.5Â°C as universal) and thermal comfort. However, the outdoor condition would be much worse than the indoor because of the substantial increase of anthropogenic heat waste released from the HVAC system. Therefore, the summer heat stress imposed by the heatwave and the UHI effect would further deteriorate the outdoor living environment and cause more heat-related deaths significantly (Kleerekoper et al., 2019).

CHANGE

The Future City From the last century, people has discovered various problems in their existing living environments, such as living space, transportation, job, health, pollution, global warming and climate change etc., and start to rethink and find the best way of planning of cities and urban areas especially for the growing population. In accordance to Ian MaHarg’s book Design with Nature (1969), the concept of planning the urban or city development basing on the nature was raised out (Abunnasr, 2019). Each type of natural resources or elements is identified, mapped and overlaid with each other in order to analyse the selected area comprehensively and propose the most suitable plan for urban development (MaHarg, 1969). Concept: Design with Nature (New) & Re-naturing (Existing) However, the idea from MaHarg (1969) is more focusing on the design of new urban areas. The Greater Sydney as an example, the use of this concept would be more suitable for the new extension of the urban area, i.e. the north-east and south-west area. For the existing urban area, i.e. the CBD area, there is a need to add the nature elements back into the urban context. Renaturing the cities with the integration of grey (urban structures), green (vegetations)

The Green • Lattice

and blue (water spaces) spaces would be necessary for the existing city improvement to bring the nature back and even future planning design with the nature (Lemes de Oliveira, 2019a). The main advantages of re-naturing the cities are summarized by Lemes de Oliveira (2019a) as below: • Fulfil the need of human connecting to the nature; • Enhance human health and well-being; • Benefit to the ecology; and • Tackle with climate change and be resilient.

Spatial Planning Model: Hybrid (Green Wedge-based) Model Considering the six principles: 1. 2. 3. 4. 5. 6.

Connectivity; Proximity; Quantity and size; Distribution and accessibility; Multi-scalar approach; and Multi-functionality

concluded by Lemes de Oliveira (2019b) in evaluating the city planning model, the hybrid planning model based on green wedge would be suggested to implement in the Greater Sydney (Lemes de Oliveira, 2019a).

p 18). It aims to connect the countryside and the inner-city area directly and to interconnect individual green space in the urban area (Lemes de Oliveira, 2019a). By integrating the other green planning models including green grid, greenways, green belt and green heart, i.e. the hybrid model (Fig. 6.1), all the six principles would be maximized and Copenhagen Finger Plan (1947) would be one of the most famous example for us to as an reference (Lemes de Oliveira, 2019b).

Green wedges were defined as â&#x20AC;&#x153;wedge-like radial green spaces, bound by development areas, often linking the urban centre with the countrysideâ&#x20AC;? (Lemes de Oliveira 2019b,

DRAFT - Greater Sydney Region Plan The NSW government published the Draft Greater Sydney Region Plan in 2017 with the vision about the Greater Sydney 2056 with a metropolis of three cities in connecting people (Fig. 6.2). This is an overall regional planning for housing, job opportunity, housing and landscape development in order to accommodate the growing population in a sustainable manner in the next 40 years in the Greater Sydney (Greater Sydney Commission, 2017). In the draft plan, a preliminary hybrid green Wedge-based model could be identified in the new city planning (Fig. 6.3). Some green corridors would be found on the basis of green wedges. However, how could these city scale designs turning into the reality and help to relieve the urban problems?

SUMMARY 6

The concept of re-naturing the city as well as the hybrid green wedgebased development model would be suitable for the Greater Sydney in a macroscopic aspect.

GREEN • CONNECT Physical Approach: Green Infrastructure (GI)

2D → 3D

In order to achieve the hybrid green Wedgebased model, green infrastructure (GI) system could be adopted to translate the model into physical reality in the implementation of the urban development (Rouse & Bunster-Ossa, 2019). In this study, Green Infrastructure is defined as “the physical manifestation of process that connect the built and natural environments performing multiple functions and yielding associated benefits for the health and well-being of people and wildlife” (Rouse & Bunster-Ossa 2019, p 175) GI is not only an element on the street, such as a role of tree, a planter or a rain garden, but also a connected network that penetrates fully in to the street, among urban buildings and structures as a whole to enhance the city resilience (Rouse & Bunster-Ossa, 2019). Besides improving the micro-climate, GI elements also help to strengthen the ecological and the social network in the local community and throughout the cityscape. It is known much about the knowledge and the technical detail for the GI elements, for example, parks, garden, green roofs, green walls and rain gardens etc. However, how could these measures be implemented as a GI system in the city? How they are distributed in the community?

The Green • Lattice

Green Infrastructure Transect across the Greater Sydney Firstly, the character and the vulnerability to the exposure to high temperature of each type of zone across the city, whatever caused by UHI effect or heat wave, would be generally identified by the Green Infrastructure Transect (Abunnasr & Hamin Infield, 2019) (Fig. 7.1).

VULNERABILITY

In section 4, it is predicated that the vulnerability to heat exposure in the suburban and the transition area in the northwest and south-east area would be the highest because of the absence of sea breeze. The areas of which the forests or grasslands is developing into urban area are the most vulnerable.

Framework for using GI to mitigate UHI effect Afterwards, a framework suggested by Norton et al. (2019) is adopted and further modified to prioritize GI to mitigate the exceed heat in the urban area of the Greater Sydney. The six steps in the framework are designed for different scales in a hierarchy so as to implement the most suitable GI to respective locations and functions. And the framework would form a cycle to evaluate the GI network in different scales, the street level, community level and the city level (Fig. 7.2).

It is possible that the major GI elements, such as, bigger urban park spaces, narrower garden spaces among buildings, green wall, green roof, rain garden, bioswale, street tree planting, permeable pavement, building forms and material favouring positive micro-climate etc, would be designed and arranged in a way similar to a 3D lattice so as to form a even more rigid and stronger network of GI in the urban area (Fig. 7.4).

Conclusion Global climate is changing and people need to adapt to it or to do something to relieve the changes. In the case of the Greater Sydney, the extreme heat is not only caused by climate change, but also the urban heat island effect strengthened by the urbanization. Urbanization is needed in order to accommodate the growing population. The problem is how we urbanize the places. As what is discussed in the introduction about “Definition of ‘Urban’ in the 21st Century”, we are now trying to change the area in a way also considering the natural system. Although the government is planning the city in accordance to the respective concepts or spatial models, the plan finally is on a flat 2D sheet. Nevertheless, the green infrastructure network formed in a 3D lattice structure considering the community, ecological and social factors would be one of the solutions to our future.

The Future Four-Dimension (4D) As the time changing, there would be changes in the 3D lattice since its connection, the people and wildlife etc., is dynamic. When, Who and How the GI elements are being used would change time to time. And TIME is regarded as the 4th dimension added to the dynamic GI lattice in the future. Hopefully, the implementation of GI lattice network would help to improve the microclimate of the urbanized areas in the Greater Sydney and to mitigate the UHI effect as well as relieve the extreme heat event when time goes by.
