Together, these various facets of infrastructure respond to the physical characteristics of a region to support the use of resources and productivity by the inhabitants beyond the boundaries of their natural habitat, with the underlying motivation for socio-economic development. In the following Sections, the present and future projection of various these various facets are discussed.
Detailed Explanation
This chunk introduces the concept of habitats and how they relate to infrastructure. It suggests that habitats, which can be defined as the natural environments in which organisms live, are integral to supporting the needs of the population. Infrastructure, therefore, is necessary not only for immediate resources but also for long-term socio-economic development. The section indicates that further subsections will delve into specific aspects and projections related to habitats.
Examples & Analogies
Think of a fish swimming in a pond. The pond represents the habitat that provides everything the fish needs to survive, like food and shelter. Similarly, the infrastructure laid in human habitats (like housing, roads, and schools) helps to provide essential services and supports the community's growth.
Definition of Habitat by EUNIS

European Nature Information System (EUNIS) defines a habitat as 'a place where plants or animals live normally, characterized primarily by its physical features – topography, plant or animal physiognomy, soil characteristics, climate, water quality, etc., and secondarily by the species of plants and animals that live there'. In 2004, EUNIS classified various habitats, such as, marine, coastal, inland surface water, grasslands, woodlands and forests, along with recognising habitats created out of human intervention, such as, cultivated agricultural, horticultural and domestic habitats, and constructed, industrial and other artificial habitats, such as cities.
Detailed Explanation
This chunk details the EUNIS definition and classification of habitats. According to EUNIS, a habitat is identified primarily by its physical properties like landscape features and environmental conditions. The classification includes both natural formations, such as forests and grasslands, and human-made environments, like cities and agricultural fields. This highlights the diversity of habitats and acknowledges that human activities have created new types of environments.
Examples & Analogies
Imagine a diverse landscape that includes a lush green forest, a bustling city, and a flat agricultural field. Just as each of these areas serves different plants and animals, they also cater to the needs of human populations in different ways, reflecting how habitats vary greatly based on natural and human influences.

In 2018, 'World Urbanisation Prospects' the UN identified very large cities with population of over 10 million as ‘Megacities’ and UN further enlisted 33 megacities of which half of these urban agglomerations are in India and China and 27 are in the developing regions of the world, termed as the ‘global south’. Globally, this is projected to rise to 43 by 2030, and the number of cities with 1 to 5 million inhabitants is projected to grow to 597. The characteristics of a Megacity are; size, rate of growth and complexity in terms of administration and infrastructure (Wenzel et al., 2007), and are the economic drivers of the country.
Detailed Explanation
This chunk focuses on the concept of megacities, defined as cities with populations exceeding 10 million. The UN highlighted that many of these megacities are located in developing countries, particularly in Asia. This growth in urbanization is significant; it indicates an increase in population density and accompanying challenges in administration and infrastructure. Megacities are considered major economic engines within their countries, reflecting their importance to national growth and productivity.
Examples & Analogies
Compare a small town with a megacity like Mumbai or Shanghai. A small town might have a laid-back atmosphere and fewer resources, while a megacity is bustling with countless opportunities and services. However, managing a megacity's needs, from keeping traffic moving to providing enough water for everyone, is much more complex.

Li, et al. (2019) analyses four major problems of Megacities from urban geography and ecology perspective, as follows; Land subsidence due to over exploitation of groundwater. Environmental problems such as, pollution, urban heat islands, urban air quality and haze, carbon emissions and dust storms, etc. Traffic congestions, parking difficulty, public transport. This is closely related to the above problems of pollution, haze, etc. Energy consumption and production that is inefficient and unsustainable.
Detailed Explanation
This chunk outlines the primary challenges faced by megacities, as identified in Li et al. (2019). These challenges include land subsidence from groundwater overuse, various environmental issues like pollution and urban heat islands, traffic congestion, and unsustainable energy consumption. Each of these problems is interconnected and can exacerbate the others, creating a complicated web of issues that megacities need to address for sustainable development.
Examples & Analogies
Consider the challenges of daily commuting in a megacity. Traffic jams are common and can lead to increased air pollution, as vehicles sit idling. Similarly, as more people utilize resources, the urban heat rises and regions may experience more extreme weather. In essence, these complex issues are like a multi-layered puzzle, where solving one piece can help alleviate pressures on others.

However, there is also the problem of declining of urban population. While large influx of population into urban boundaries is on rise, most of these cities also face high risk of population decline and loss of life due to geographical location, mostly coastlines, and consumption patterns are the vulnerable to at least one of the 6 types of natural disasters – cyclones, floods, droughts, earthquakes, landslides and volcanic eruptions.
Detailed Explanation
This chunk discusses an interesting contradiction: while many megacities are experiencing population growth, they are simultaneously at risk of declining populations due to natural disasters and poor living conditions. Cities located near coastlines often face severe natural disasters, which can displace residents and lead to a decline in population. The interplay between urban growth and geographical vulnerability highlights the precarious nature of megacity living.
Examples & Analogies
Think of a beachfront community that attracts tourists but struggles with hurricanes every year. While it may see an influx of residents and visitors trying to enjoy the beauty, the threat of storms means that some residents may choose to leave, demonstrating the delicate balance between attraction and vulnerability in urban settings.
Impact of Megacities on Global Change
Unlock Audio Book

Krass (2007) noted how megacities affect global changes, enlisted below, and in turn, are affected by them. These changes may include geo-ecological changes like pollution, sea level rising, global warming; geo-economic changes like globalisation, international labour division; geo-social changes such as urban disease, social justice; geo-cultural changes including urban ethnicity and social movements; and geo-political changes like resource security and welfare.
Detailed Explanation
This chunk emphasizes the bidirectional influence of megacities and global changes. Megacities contribute to geological and socio-economic changes while being impacted by them. For example, pollution and the effects of climate change lead to more significant socio-economic issues, such as resource insecurity. This interconnected relationship highlights how megacities can shape and be shaped by global patterns in various dimensions.
Examples & Analogies
Think about how a famous city like New York influences and is influenced by global trends. As migration patterns shift and global capital flows into the city, it simultaneously affects local economies, social justice issues, and even climate strategies, to create a dynamic interplay.
