  2. MODULE 1 INTRODUCTION TO COURSE AND OVERVIEW Civil Engineering societal and global impact deals with the outcomes of civil Engineering Projects. It can be positive or negative. In this rapid increase in construction there is the need to study their impacts on our society and globe. So, this subject is go be dealing with the several types of impacts.
  3. Pre-industrial society refers to social attributes and forms of political and cultural organization that were prevalent before the advent of the Industrial Revolution, which occurred from 1750 to 1850. Pre industrial society Pre- industrial is a time before there were machines and tools to help perform tasks in mass. Pre-industrial civilization dates back to centuries ago, but the main era known as the Pre-industrial society occurred right before the industrial society. Pre-Industrial societies vary from region to region depending on the culture of a given area or history of social and political life. The Indian subcontinent was known for its spread of Islam by the Delhi Sultanate and Mughal Empire, which later caused the emergence of the proto- industrialization, while Europe for its feudal system and the Italian Renaissance
  4.  The agricultural revolution is the name given to a number of cultural transformations that initially allowed humans to change from a hunting and gathering subsistence to one of agriculture and animal domestications.  The Neolithic or agricultural revolution resulted in a demographic transition and major increases in population (Table 6.1) and population density (Table 6.3). The population of hunter–gatherers rose at a very low rate constrained by the carrying capacity of the land (see Chapter 4, Fig. 4.1). The increase in Paleolithic global populations parallels the increase in range as humans migrated from Africa to Asia, Europe, the Americas, and Australia. The increase in the growth rate of human populations increased by as much 60-fold with the Neolithic Revolution (Table 6.1). “Population, when unchecked, goes on doubling itself every twenty-five years or increases in a geometrical ratio” (Malthus, 1798). This is seen in the USA with the population rising from 2.5 million in 1776 to 5.3 million in 1800 to 11.1 million to 1825 and 23.2 million in 1850 (US Census, in press); the population growth being unchecked as more land came into cultivation. Agriculture Revolution
  5. 1st and 2nd Industrial revolution  The First Industrial Revolution began in the 18th century and focused primarily on textile manufacturing and steam power. During this time period inventors across Europe and the United States created devices and machines that mechanized production. For example, the steam was a vitally important invention to the revolution because it lessened the need for manual labor. The first steam engine was created by Thomas Newcomen in 1712. Newcomen produced items for tin mine owners who often complained that they were struggling to deal with flooding in their mines. Traditional methods of removing water from the mines were slow, and hard work. Newcomen realized that he could help the tin mine owners. He developed a pump engine that used a piston in a cylinder; it was the first of its kind. In the 1760’s, James Watt improved on and perfected the design first produced by Thomas Newcomen. In 1764, Watt was given a Newcomen steam engine to repair. He started working on it and soon realized that it was inefficient. As a result, Watt wanted to improve the design. He was successful, and found a way to prevent steam from escaping from the engine by adding a separate condensing chamber. Watt patented his new steam engine design, and it paved the way for other mechanical design work.
  6.  The Second Industrial Revolution began in the mid-19th century and continued until World War I in 1917. While the First Industrial Revolution centered on textile manufacturing and the innovation of the steam engine, the Second Industrial Revolution focused instead on steel production, the automobile and advances in electricity. Discoveries in the field of electricity improved communication technologies. In 1866, the first underwater telegraph cable across the Atlantic Ocean was successfully installed, and ten years later, Alexander Graham Bell invented the telephone. In the late 1800’s American Thomas Edison produced an amazing array of inventions. Among them were the phonograph and the incandescent light bulb. In 1886, German scientist Gottlieb Daimler devised an internal combustion engine that was fuelled by gasoline and could power a small vehicle. His invention was one of the biggest advances in transportation technology since the development of the steam engine. Daimler would use his engine to create one of the first automobiles. An improvement in production was the introduction of the assembly line by Henry Ford in 1914. On an assembly line, the complex job of assembling many parts into a finished product was broken down into a series of small tasks. It sped up production and reduced costs as each worker was only required to install one or two parts at their position on the assembly line. Ford would use the assembly line to speed up the production of automobiles in his factory in Highland Park, Michigan.
  7. IT Revolution  India has had phenomenal growth as a country over the course of the past 75 years since achieving independence. Following India's IT revolution, the country's export of IT services increased from a meagre $3.5 million in 1980 to over $100 billion in 2016-17. India's IT growth is vividly described by government policies, technical developments, and industrial leaps. All of this contributes to what it is today: the introduction of computers and the internet to India, the implementation of computerized reservations by the Indian Railway, and the role that commercial and governmental policies had in the development of IT.
  8. Recent Civil Engineering Breakthrough and innovation The Statue of Unity is the world's tallest statue, with a height of 182 metres (597 feet),[3] located near Kevadia in the state of Gujarat, India. It depicts Indian statesman and independence activist Vallabhbhai Patel (1875–1950), who was the first deputy prime minister and home minister of independent India and an adherent of Mahatma Gandhi. Patel is highly respected for his leadership in uniting 562 princely states of India to form the single Union of India. The statue is located in Gujarat on the Narmada River in the Kevadiya colony, facing the Sardar Sarovar Dam 100 kilometres (62 mi) southeast of the city of Vadodara.[4] The project was first announced in 2010, and construction started in October 2013 by Indian company Larsen & Toubro, with a total construction cost of ₹27 billion (US$422 million).[5] It was designed by Indian sculptor Ram V. Sutar and was inaugurated by the Prime Minister of India, Narendra Modi, on 31 October 2018, the 143rd anniversary of Patel's birth.[6]

  11. Present day world and future projections Vision for civil engineering states a new reality, one that does not exist today. Part of that reality is encapsulated in several overarching concepts that precede the Vision statement: civil engineers are: I. Entrusted by society II. Create a sustainable world III. Enhance the global quality of life IV. Serve competently, collaboratively, and ethically V. Demonstrate a mastery and leadership “Entrusted by society” stands out as a major component and a heady challenge. Through their demonstrated abilities and roles of civil engineers will have earned society’s trust and will be regarded as key leaders and advisors in both delivering the world’s built environment and sustaining the natural environment. Entrusted by society to create a sustainable world and enhance the global quality of life, civil engineers serve competently, collaboratively, and ethically as master., planners, designers, constructors, and operators of society’s economic and social engine—the built environment. Civil engineers will serve as master builders and integrators, leading multidisciplinary teams of professionals and paraprofessionals. The civil engineer needs to have mastered a comprehensive body of knowledge, change is necessitated by forces such as globalization; sustainability requirements; emerging technology; and increased complexity with the corresponding need to identify, define, and solve problems at the boundaries of traditional disciplines.
  12. Ecosystems in Society and in Nature What is a social ecosystem? A social- ecological system consists of ‘a bio-geo- physical’ unit and its associated social actors and institutions. Social-ecological systems are complex and adaptive and delimited by spatial or functional boundaries surrounding particular ecosystems and their context problems. A natural ecosystem is a community of living and non-living entities and occurs freely in nature. Every component interacts together as a combined unit through physical, chemical and biological processes. The discriminating factor of natural ecosystems from other ecosystems is that they are completely natural.
  13. Global warming, its impact and possible causes What is Global Warming? Global warming is the phenomenon of a gradual increase in the temperature near the earth’s surface. This phenomenon has been observed over the past one or two centuries. This change has disturbed the climatic pattern of the earth. However, the concept of global warming is quite controversial but the scientists have provided relevant data in support of the fact that the temperature of the earth is rising constantly. Causes of global Warming Deforestation Use of Vehicles Chlorofluorocarbon Industrial Development Agriculture Overpopulation Volcanoes Water Vapour Melting Permafrost Forest Blazes

  17. Human Development Index and Ecological Footprint of India Vs. other countries and analysis  India ranks 132 on the Human Development Index as global development stalls  The Human Development Report shows that progress globally is in reverse. India’s decline in human development mirrors this trend – impacted by intersecting crises. But there is good news. Compared to 2019, the impact of inequality on human development is lower. India is bridging the human development gap between men and women faster than the world. This development has come at a smaller cost to the environment. India's growth story reflects the country's investments in inclusive growth, social protection, gender-responsive policies, and push towards renewables to ensure no one is left behind," says Shoko Noda, UNDP Resident Representative in India.
  18. THE ECOLOGICAL FOOTPRINT OF INDIA  In 1996 the concept of ecological footprint was created. It became a valuable index for measuring the pressure of the human beings on the biosphere. It helps to understand the amount of resources we use and the emissions we produce to support our lifestyle. The comparison between the rates obtained for each country can distinguish those who have a lighter ecological footprint, which contribute little to threaten the environmental destruction, and those who have a heavier footprint, with a strong negative impact on the sustainability of our civilization. The ecological footprint measures the pressure on natural resources due to population consumption and life style. It estimates the biologically productive area required to provide the natural resources we use in our daily life: the resources used in the house we live in, the furniture and objects, clothes, transportation that we use, what we eat, what we do at leisure and to absorb carbon dioxide emissions.  It is measured in global hectares (gha), and global hectares per capita (gha/pc). A global hectare quantifies the biocapacity and measures the average productivity of all biologically productive areas in a given year. A global hectare per capita refers to the amount of biologically productive land and water consumed per person. The United Arab Emirates (10.7 gha/pc), Qatar (10.5) and the United States (8.0) are those with heavier ecological footprint per capita, i.e., they threaten the global sustainability. An average German uses 5.1 hectares, a Brazilian, 2.9; a Chinese, 2.2. In Japan 4,7. Russia, 4.4, Portugal, 4.5, Argentina, 2.6. The average Indian has an ecological footprint of 0.9 gha/pc. The global footprint is 2.7 global hectares per capita. If the entire population of the planet adopted a lifestyle similar to the U.S., we would need four planets Earth because the biocapacity of a single planet is insufficient to sustain the demands of the population.
