Abstract The relationship between water abstraction and water availability has turned into a major stress factor in the urban exploitation of water resources. The situation is expected to be sharpened in the future due to the intensity of extreme meteorological phenomena, and socio-economic changes affecting water demand. In the city of Volos, Greece, the number of water counters has been tripled during the last four decades. This study attempts to simulate the city's network, supply system and water demand through a forecasting model. The forecast was examined under several situations, based on climate change and socio-economic observations of the city, using meteorological, water pricing, users' income, level of education, family members, floor and residence size variables. The most interesting outputs are: (a) the impact of each variable in the water consumption and (b) water balance under four management scenarios, indicating the future water management conditions of the broader area, including demand and supply management. The results proved that rational water management can lead to remarkable water conservation. The simulation of real scenarios and future situations in the city's water demand and balance, is the innovative element of the study, making it capable of supporting the local water utility.

Millennials have been touted as the generation that will do something about global warming. Conversely, some social scientists studying generational differences have found evidence that younger generations are less likely to engage in civic matters like environmental activism. Lack of civic engagement among Millennials may reduce their likelihood of engaging in collective action on global warming. On the other hand, the world is drastically changing. Within the recent years, climate change has become a growing concern worldwide. The various modes of destruction imposed on the environment are targeted to be the catalyst to these changes. According to climate scientists, sea level rise is one of the most important impacts of global climate change. Fishermen as one of the professions that depend their life on the sea, is affected so much by this condition. This condition might destroy their houses on the coastal area. Urban Kampong in Jakarta as the most dense human settlements in urban area has become one of the main economic generator for a city. With all the contradict characteristics and forms, urban kampongs are the part of the city that cannot be separated from one to another. The existence of kampong has become the main embryo of the development of Jakarta. Jakarta is one of the biggest coastal city in the world. The coastline of this city has become the main economic generator for the coty and the nations. The existence of fishermen’s kampong in Jakarta has also become an essential program for the city, in order to fullfill the needs of fresh catch of sea products. Therefore, The project is aimed to create a sustainable and adaptive coastal kampong community, that has the resilience to the rising sea level. By concerning on the kampong’s behaviour, and doing research of the typological transformation of the kampong, the design is also expected to serve as an archetype fot the future development of endagered coastal settlements all across the country. several sustainable approach and behaviourial approach are also injected in this project to create a contextual design that would help the kampong to grow, and adapt to all the conditions, and situation in the future. AbstrakGenerasi milenial dianggap sebagai generasi yang akan melakukan perubahan nyata terkait dengan pemanasan global. Akan tetapi, beberapa studi pun menunjukan bukti bahwa generasi millenial justru memiliki kesadaran serta kepekaan yang tidak lebih tinggi dibandingkan dengan generas-generasi sebelumnya. Pada satu sisi, bumi kian melakukan perubahan yang begitu derastis. Berbagai macam kerusakan pun terjadi dalam berbagai jenis yang menjadi generator dari perubahan iklim yang drastis ini. Nelayan sebagai salah satu profesi yang menggantungkan nasibnya pada lautan, kian terganggu dengan kondisi ini. Hal ini menyebabkan kerusakan pada rumah-rumah di kawasan pesisir pantai. Kampung kota di Jakarta, sebagai permukiman terpadat di daerah urban menjadi salah satu kenerator utama pada suatu kota. Dengan segala karakteristiknya yang berbanding terbalik dengan perkotaan, kampung kota merupakan bagian yang tidak dapat dipisahkan dari suatu kota. Eksistensi suatu kampung telah menjadi embrio dari perkembangan kota Jakarta. Jakarta merupakan salah satu kota pesisir terbesar di dunia. Daerah pesisir dari kota ini telah menjadi generator ekonomi utama dari kota itu sendiri dan juga nasional. Keberadaan kampung nelayan di Jakarta pun menjadi salah satu program penting yang perlu mendapatkan perhatian. Maka dari itu, proyek ini bertujuan untuk menciptakan suatu komunitas kampung pesisir yang berkelanjutan, adaptif serta memiliki ketahanan terhadap kenaikan permukaan air laut yang terjadi. Metode perancangan pada proyek ini dibagi menjadi 2 bagian utama yaitu analisis mikro yang membahas mengenai tipe dan perilaku, serta analisis makro yang membahas proyek dari segi perancangan urban. Dengan menitik beratkan pada studi perilaku, dan melakukan riset mendalam terhadap transformasi tipologi yang terjadi pada kampung, desain ini diharapkan dapat menjadi suatu arketipe untuk pengembangan kampung di daerah pesisir di masa depan di seluruh Indonesia. Sehingga dapat disimpulkan, bahwa dengan adaptasi tipe, perilaku serta sistem berkelanjutan yang sesuai dan tepat, desain dari kampung nelayan berkelanjutan ini dapat menjadi suatu respon yang tepat dalam menjawab permasalahan yang terjadi di kampung-kampung pesisir.

The urban cores are considered as the most crucial clusters of the contemporary urban cities as they are the foremost economic growth poles that cater to the needs of the city population. These clusters are facing urban development issues like congestion, longer travel distances and time, pollution, etc., hence, transforming into a non-livable environment. Smart development has been identified as a world-wide solution to the existing urban development issues which focuses on promoting a sustainable and livable environment with the integration of ICT; acts as an implementation tool. Ludhiana; regarded as the Manchester of India, is the most industrialized city of the northern India. The city has a strong economic base due to the presence of commercial hub and small and large manufacturing industries which have acted as a catalyst for rapid urbanization. The city has witnessed immense population growth over the last 5 decades which has led to issues such as pollution, environment degradation,, emergence of slums and failure of physical and social infrastructure; thus failing to be a livable city. The paper intends to identify the urban development issues in Ludhiana city core and provide appropriate strategies based on the Smart Development principles.

<p>In 2018, the UN estimated that around 55% of the world’s population currently live within urban areas, with this value projected to rise to 60% by 2030 (United Nations, 2018). High levels of urbanisation, coupled with an increasing trend in extreme weather under future climate change scenarios, combine to create significant challenges to increasing urban resilience for the future (Masson et al., 2020).</p><p>Urban climate services provide tools to support decision making at a range of scales across the city, from day-to-day operations to informing urban design over longer timescales (Grimmond et al., 2015). Whilst urban climate services may be developed at a range of scales (Grimmond et al., 2020), this presentation looks at a prototype climate service which provides long-term climate change projections at the city-specific scale. The ‘City Pack’ was developed through a process of co-production, in which project development aims to move away from a one-way push of scientific information, to a two-way collaborative process of knowledge construction and sharing (Vincent et al., 2019).</p><p>This ‘City Pack’ service was co-developed by the Met Office and Bristol City Council following an assessment of the Council’s climate information needs. The City Pack comprises of three non-technical factsheets which explain how the climate of Bristol has changed and will continue to change into the 21<sup>st</sup> Century based on the UKCP climate projections. The City Pack’s primary aims are to raise awareness of how a cities climate may change in the future and to inform the development of city resilience whilst also providing a tool to be used by city stakeholders to raise awareness of climate change across the council. The audience for the City Pack therefore includes city officials, city planners and the general public. The Bristol City Pack has since provided an evidence base for the Bristol City Council Climate Change Risk Assessment and informed Bristol’s Climate Strategy. In addition, the City Pack has been used to engage with the council’s wider stakeholders and also as a communication and training tool. As such, whilst the co-production of a climate service may be time and resource intensive, the process may also be rewarded with the production of a highly tailored and user-relevant tool.</p><p>Following the success of the prototype ‘City Pack’ service for Bristol City Council, the Met Office are continuing to produce City Packs for additional cities across the UK, and also in China. The project is seeking to ascertain if services which are co-produced with and bespoke to one set of stakeholders, may provide an equally valuable service for other cities and if so, how can we make these services scalable.</p>

The city Ho Chi Minh (HCMC) is one of the largest cities in Vietnam with the most dramatically economic development rate. Along with the economic development, the urbanization process in this city is also taking place very fastly. Due to the rapid urbanization and development, the emission rate from the industry and transportation leads to the increase in the amount of carbon dioxide (CO2) which has been worsening the climate change. Protecting forests and conducting afforestation so that CO2 is transformed to nutrition through photosynthetic conversion is one of the most effective ways to mitigate the effects of climate change. As a result, the accumulation of CO2 emissions has become a global concern. Vegetation absorbs carbon dioxide, helps to conserve the environment, produces oxygen, reduces noise, and helps to stabilize subsurface water. This paper highlights the results of ENVI software which was used to interpret remote sensing images and Arcgis to evaluate the amount of carbon dioxide absorbed by vegetation in each administrative unit: district in HCMC and ward. According to the obtained results, the amount of CO2 absorbed in urban districts “District 1”, “District 3”, “District 4”, “District 5”, “Phu Nhuan District” is immensely low due to the high population density in the center of city. The population is mainly concentrated in the center districts but land area for vegetation is low. Regarding the suburban area, with mangrove forests, Can Gio District has the highest amount of CO2 absorbed of 35,894.075 tons/day and followed by Cu Chi District with 21,548.48 tons/day. It can be indicated that Can Gio and Cu Chi districts improtantly function like the greenhouse gas sinks for the whole HCMC. The success of this study could contribute to climate change mitigation and support in urban and land planning, as well as resettlement policies. Aside from that, CO2 emission and absorption assessment and evaluation in large–scale cities like HCMC has become a crucial, urgent, and practical issue nowadays.

<p>Kolkata’s city core is getting depopulated but has experienced an explosive population growth leading to rapid urbanization which is encroaching the ecologically fragile wetlands of the eastern fringe of the main city. This contrasting urban growth along the East Kolkata wetland is accounted mainly for the increase in city size, expansion of tertiary and service sector activities especially the IT boom, and the improved transit facilities along the eastern fringe. This has helped the real estate sector to thrive along the vulnerable eastern fringe of the city, leading to a drastic change in the wetland ecosystem. Secondary studies have also indicated that consumption of wetlands, indicated by fragmented land use has altered the microclimate of Kolkata. The significant land cover change due to human-induced perturbations has led to an insurgence of temperature in the region <strong>(Li, Mitra, Dong, & Yang, 2018)</strong>. The entire transit corridor is subjected to verticalization juxtaposing the cultural essence of Kolkata bringing with it a myriad of Economic, Social, Cultural and subsequent planning challenges. The critical review of the selective literature shows how the best planning practices have integrated transit policies with land use. This has further helped the researcher in formulating strategies and policies specific to the regional context in order to render sustainable development in the study area. The study explores how the transit policies in Kolkata have actually transformed the city physically, socially, culturally and changed its microclimate. The study identifies future trends and assesses the future development potential, intensification with the help of qualitative and quantitative analysis. The study also conducts land suitability analysis for framing proposals and recommendations for ensuring sustainable development along the East Kolkata Wetland.  The outcome of this study is a methodology for sustainability strategic planning for developing the growth node along the eastern fringe of Kolkata which will curb the encroachment of the East Kolkata Wetlands. The study also provides a platform for policy recommendations for land use management and mitigate future climate changes in this eco-fragile zone.</p><p>Keywords: landuse; climate change; transit policies; sustainable planning; wetlands</p><p>Reference</p><p>Li, X., Mitra, C., Dong, L., & Yang, Q.

Seeking to govern the city in relation to climate change is a political project that at once imagines the present in terms of the future and the future in terms of the present. The urban politics of climate change has brought multiple visions of the possibilities (and limits) of urban futures. In this context, we find urban responses taking experimental form – creating sites through which to explore and experience different futures. They provide spaces in which utopian visions can be imagined, enacted and contested. Conceptualizing urban climate change experiments as heterotopic sites seems fruitful in at least two regards. Firstly, it captures their provisional and ambivalent relationship with the broader urban milieu. Secondly, and even more critically, it opens up the dialogues between the future and present which are at the heart of the climate governance project, and highlights the spatial form of these politics. We examine both with reference to two examples of climate experimentation in Berlin and Philadelphia.

Abstract. Urban development increases flood risk in cities due to local changes in hydrological and hydrometeorological conditions that increase flood hazard, and also to urban concentrations that increase the vulnerability. The relationship between the increasing urban runoff and flooding due to increased imperviousness better perceived than that between the cyclic impact of urban growth and the urban rainfall via microclimatic changes. The large-scale, global impacts due to climate variability and change could compound these risks. We present the case of a typical third world city – Can Tho (the biggest city in Mekong River Delta, Vietnam) – faced with multiple future challenges, namely: (i) climate change-driven sea-level rise and tidal effect, (ii) increase river runoff due to climate change, (iii) increased urban runoff driven by imperviousness, and (iv) enhancement of extreme rainfall due to urban growth-driven micro-climatic change (urban heat islands). A set of model simulations were used to assess the future impact of the combination of these influences. Urban growth of the city was projected up to year 2100 based on historical growth patterns, using a land-use simulation model (Dinamica-EGO). A dynamic limited-area atmospheric model (WRF), coupled with a detailed land-surface model with vegetation parameterization (Noah LSM), was employed in controlled numerical experiments to estimate the anticipated changes in extreme rainfall patterns due to urban heat island effect. Finally, a 1-D/2-D coupled urban-drainage/flooding model (SWMM-Brezo) was used to simulate storm-sewer surcharge and surface inundation to establish the increase in the flood risk resulting from the changes. The results show that, if the city develops as predicted, the maximum of inundation depth and area in Can Tho will increase by about 20%. The impact of climate change on inundation is more serious than that of urbanization. The worse case may occur if the sea level rises 100 cm and the flow from upstream happen in the high-development scenarios. The relative contribution of causes of flooding are significantly different at various locations; therefore, detailed research on adaptation are necessary for the future investments to be effective.
