Abstract Mahanagar Gas Limited is a City Gas distribution (CGD) company based out of the city of Mumbai and around. MGL currently has around 480 Kms of Steel gas pipelines for transportation of natural gas. The diameters of these pipelines are ranging from 2” to 18” and almost all are coated with 3 layer Poly Ethylene coating (3LPE). We are installing Permanent Cathodic Protection (PCP) for all commissioned pipelines and Temporary Cathodic Protection (TCP) having a design life of 5 years for un-commissioned pipelines during the projects stage itself. This paper shall basically outline the CP system in MGL along with various practices being followed in MGL to ascertain the effectiveness of CP. MGL has installed various CP assets like CP stations, Diode stations, external ER probes, corrosion coupons to ascertain the CP effectiveness. This paper shall outline the detailed monitoring procedure along with monitoring frequency of all the assets. MGL is also carrying out health adequacy surveys like DCVG, CIPL etc over the steel pipeline network. Few case studies arising out of these monitoring results shall be presented in this paper. (1) Casing carrier short at Taloja Railway crossing. The detailed procedure of monitoring and rectification shall be presented. (2) Case study on CP under-protection at Andheri which was resolved using a flange isolation kit.

The paper examined and brought to the fore the typical characteristic of urban and peri-urban farmers in Freetown and Bo communities which serves as major source of supply of agricultural products into the cities’ markets. The social and environmental aspect and perception of producers involved in urban and peri-urban agriculture was examined. Descriptive statistics and pictograms were used to analyze and present the data. Results indicate that 56.34% never went to formal school and mostly dominated by women, showing that farming became the alternative means of livelihood support for those groups. Crops grown are purely influenced by market orientation—demand and cost, as is evident in Gloucester (lettuce, cabbage and spring onions). Potato leaves were commonly grown in almost all communities, reason being that it serves as common/major sauce/vegetable cooked in every household in Sierra Leone. Maize and rice were featured in Ogoo farm—government supervised land set aside purposely for growing crops to supply the city. Findings also revealed that majority of the farmers are resource poor, judging from calculation about their monthly income earning and available household assets and amenities. About 70.4% of the lands the farmers grow their crops on is leased for production. Except for Gloucester community, when costs of production will be summed, minimal benefit seem to be realized from the farming activities. Even though some of these farmers are engaged in organization, many have limited access to micro financial organization that would probably loan them money to upscale production.

Abstract. Flood is one of the greatest disasters in the world, and the cause of a lot of damages to buildings and Agricultural products every year. Gorganrood river crossing the city of Aq’qala and it is always under flood risk. In the spring, due to the high intensity rainfall and melting of the snow, upstream areas bring much water into the Gorganrood river. On 23rd March, 2019 occurred a terrible flood in Aq’qala passing discharge 650 (m^3/s), it would occur every 100 years in this river. This river in normal time is passing discharge approximately 120 (m^3/s). A large of an urban and non-urban area was affected by this flood and mapping and analyzing of this flood have a key role for river and disaster management. Remote sensing is one of the best ways to flood mapping, especially in flood time weather is cloudy, Therefore, Synthetic Aperture Radar (SAR) images had high potentiality for flood analysis. In this study the Sentinel-1 data used for flood studying due to free available and shorter revisit time. After the processing has done, by selecting the VV band the flooded areas detected. After that overlapped the images and combination of RGB bands and the change the value of pixels, at last, we will be able to obtain the flood mapping images for Gorganrood river. In the primary days of the flooding, almost all the northern regions of the city were flooded, and during a week about 96.8 (km^2) city flooded.

Bridgeheader is one of the typology of low-income people in the city who assume that the house is only ‘a springboard’ for their life in the city. This group of people dwelt not far from the location of their place to work; occupying marginal spaces in the city and its environment tend to be slump. Almost all areas in the city of Jakarta have marginal spaces, therefore the government attempt to improve the quality of their houses, for example by providing low-cost housing. In fact the low-cost house which was provided by the government failed to be ‘consumed’ by the brigdeheaders at the time when the used value of the house has been turned into market value. The research aimed to determine such approaches of use value of the house that can be ‘consumed’ by the brigdeheader, but did not undermine the space in the city. Data collection methods using practical observation conducted with interviews. While the analysis using descriptive pragmatic method in four case study area in Jakarta. The findings indicate that the concept of house for this group is not determined only by the ‘low price tag’ but also ‘the way of use’ of the space contributed with the result that the house can be ‘consumed’ well.

The refurbishment of educational buildings usually involves a variety of measures aiming at reducing energy demands and improving building functionality to achieve higher living comfort. This paper aims to develop an approach for determination of comprehensive refurbishment strategy upon existing preschool buildings in Slovenia from the aspects of energy and economic efficiency. The main idea of the approach is to separate and individually analyse the investments into those related to energy efficiency improvements and those related to improvements of building functional quality through the step-by-step evaluation of individual measures. The proposed approach was applied on the case study of the existing timber preschool building in the city of Maribor. Generally, the highest energy savings are detected only in the case of combination of multiple renovation measures. Moreover, the economic indicators show low efficiency for almost all measures if they are treated separately. Additionally, the analysis reveals that certain measures are totally inefficient in terms of energy, yet they are highly beneficial from the viewpoint of building functional quality, which indicates the importance of the multi-perspective assessment of renovation process. The conclusions of this study can be implemented to similar building types and construction ages in similar climatic and economic environments.

Contamination Problem

ABSTRACT Numerous above-ground and underground oil storage tanks and underground piping present a significant groundwater pollution threat when breached or deteriorated. The principal aid in cleaning up a spill on land or at sea is being able to observe it, and this opportunity is lacking in the case of the groundwater incident. A groundwater incident can be equally as damaging to the environment as a surface spill and can directly impact the public health by contaminating drinking water or creating hazardous atmospheres in cellars, storm drains, and sewers. In March 1991, when oil was found leaching from the bank of a river trench leading to the Cape Fear River, the Coast Guard Marine Safety Office (MSO) in Wilmington was able to control the oil in the trench through traditional use of booms and sorbents. The MSO was confronted with the threat of oil contaminating ground water and the challenge of locating the source. This report outlines the decisions, actions, and events surrounding the response to the groundwater contamination problem at the City Gas and Transmission facilty.

Abstract The city has become the place of sustainability and public space is one of the main elements of this concept: it does not consume land, it recovers the existing building assets, it works with requalification, re-design, accessibility and availability. In this sense, public space takes on an ecological and environmental connotation, supported by a growing respect for nature. Nowadays, in historical small towns, all works addressing the public space acknowledge an overlapping of traces and testimonies that identify those space as assets to be protected, but also made available to the public. In this regard, it is also necessary to protect the buildings that define this space. A tool is enhancement. Enhancement means taking actions aimed at giving value. Its objectives focus by integrating the architectural heritage into contemporary life, by strengthening social development, as well as the economy, and defining its roots and identity. Today, enhancement connects the past with the future and provides an occasion to highlight the tangible and intangible resources safeguarded by such heritage. For ordinary heritage the only possible strategy is represented by eco-museums, through a systemic approach towards all tangible and intangible elements. The case study is a very small town in the country of Ragusa, Sicily, Italy, is considered a “cultural, natural and architectonical landscape” and reflects the combined works of nature and humankind, where cultural heritage is located both in rural areas, both in center of town. The city has an interesting old town consisting in two important historical area: Matrice district and San Giovanni district. In them there are small palaces built almost all after the earthquake of 1693, beautiful churches even older, beautiful woods and views that design public space. This research is aimed at retrieving the present architecture and landscape by using the existing structures to leave an indelible mark on renovation projects. The enhancement project guides the birth of the eco-museum; it identifies, selects and recovers the existing building assets, proposing attractive and economically interesting functions for public space. An action based on eco-museums helps breathing new life into a community and its heritage, promoting life, economy and tourism.

With the technological advancement of ICT, the cities of the world are becoming so dependent that ICT is challenging the conventional ideas and classic theories of city structure. The cities of the world are undergoing a transition that is caused by the shift of principle from ‘physical movement’ to ‘virtual movement’. The state-of-the-art ICT featured by internet and e-commerce (Business-to-Commerce - B2C) is facilitating such shift which influences in changing the conventional ideas and structure of CBD, core business areas, city center, etc. Though the magnitude of influence on the transition process is yet to be known, there is an obvious transition that almost all cities of the world are experiencing. This book chapter conceptually discusses and portrays the potential changes in the conventional city structure by analyzing three classic city models (i.e., multi-nuclei, concentric and sector models), exploring the technological advancement in ICT and increasing dependencies on it and by drawing evidence from a pilot case study. This chapter argues that ICT induced change in the city structure, which we may call ‘future city’ or ‘transitional city’, would bring positive impacts on the physical and social environment, competitive land and transportation system in the city.

Learning outcomes This case study focuses on the problems that a company have in segmenting a local market of a gas distribution company and some strategies that they can use for developing a viable market segmentation to target the right segment that will provide a good economics, revenue base customers who also have the mindset to change to a new product. At the end of this exercise, students should have a clear understanding of the following: the essentials concepts of market segmentation, targeting and positioning and how they can be leveraged so that businesses increase their returns; the main elements/steps that drive market segmentation and business positioning; the appropriate methods for market segmentation when targeting local markets for a city gas project; and the challenges companies might face when changing a product. Case overview/synopsis In 2018, commercial customers began asking Abu Dhabi National Oil Company (ADNOC) Distribution to provide a sustainable solution to ensure a continuous supply of safe gas and avoid the interruptions and hazards associated with the supply of liquefied petroleum gas (LPG) to their premises. The request was discussed with the ADNOC marketing, supply and trading (MST) Division to investigate the possibility of growing the natural gas business in the Emirate of Abu Dhabi, thus contributing to the Emirate’s security, economy, environment and community, and ultimately to ADNOC Strategy 2030. Khaled Salmeen, Director of the ADNOC MST Division, believed that industrial customers accounted for higher business volume and profitability. Nevertheless, he advised Shuhab Al Shehhi, the City Gas Project Manager, to study the potential benefits in targeting both residential and commercial customers as part of ADNOC’s responsibility towards community engagement and investments. Al Shehhi had to address several questions: How could the City Gas Project be strategized and positioned so as to target all market segments? What were the potential outcomes? Would targeting all market segments strengthen ADNOC’s brand position?
