Challenges faced by megacities – what are the responses?

Remember the box office hit ‘Slumdog Millionaire’?

Set in the Indian megacity of Mumbai, the movie provides a realistic depiction of the challenges faced by individuals, and more broadly, communities in these large urban agglomerations. Such challenges include a lack of access to employment, housing and shelter, transport infrastructure, and the poor establishment of sewage systems contributing to the absence of a healthy living environment.

Challenge: access to housing and shelter

Remember the 2016 Rio de Janeiro Olympics?

The Rio Government’s strategy to build the Olympic facilities was to the detriment of favelas, displacing thousands of individuals. Those who live in shantytowns, slums and favelas have no legal rights over the land in which they inhabit – hence rationalising the Rio government’s decision to destroy communities to make way for an international sporting event.

  • A 2015 estimate states that 27% of Rio’s population live in favelas (informal housing also known as shanty towns).
  • In addition, 30% of Rio’s population is not connected to a sanitation system.

Sadly, the Rio Olympics is not the only example of where individuals have been displaced due to the informality of their housing. Another example includes the 2010 Commonwealth Games in New Delhi, where the government practiced forced evictions of populations within shantytowns and slums.

However, it doesn’t only take large events such as the Olympics or Commonwealth Games to displace individuals, as the lack of access to adequate housing is such a widespread and pressing issue faced by communities in the developed world; posing as one of the greatest modern humanitarian crises.

Response: access to housing and shelter

Site and service projects are one of the responses to the lack of shelter and housing in mega cities. This project aims at providing tracts of urban land, which are divided into plots, and provided with basic support services, for example electricity, water and sanitation. These plots are then sold or leased to those who choose to build their own homes on. This idea has been implemented in Mumbai.

However, as discussed above in the challenges associated with a lack of access to housing and shelter, there are great limitations to the implementation of site and service projects, including the reality that governments have not been active in promoting change to improve the living standards of residents to informal housing arrangements.

Challenge: access to employment

The lack of access to employment poses as one of the largest challenges in which those living in mega cities face.

  • The World Bank estimates that 25% of the urban population in Less Economically Developed Country’s (LEDCs) megacities live in absolute poverty
  • The International Labour Organisation suggests 20-25% of urban adults in LEDC megacities are without regular work.

For this reason, many megacities operate within a ‘dual economy’.

  • Put simply, dual economies operate where there are two different employment sectors – the formal sector employs the populace with an occupation, which is officially recorded by the state (i.e. employees pay taxes to the government etc.), and an informal sector (i.e. employees do not pay taxes to the government)

A dual economy creates a multitude of negative ‘spin off’ effects, how many can you think of? (HINT: think of how persons in the informal economy don’t pay taxes… what are the implications of this?)

Response: access to employment

  1. The provision of microcredit / microfinance

Many NGOs provide micro financing to small vendors in megacities to legalise and register the business to become recognised by the government, hence eliminating some of the key implications which the dual economy creates.

  1. Creation of formal employment via the generation of infrastructure projects

Not only responding to the dual economy, however also the lack of access to transport infrastructure – the creation of formal employment can be achieved through government projects to improve public facilities.

Challenge: establishment of water and sewage systems

Another challenge faced by mega cities is the establishment of water and sewage. This includes lack of safe drinking water and untreated sewage waste, as well as a multitude of other issues. In response to this, many NGOs and Human Rights campaigns are attempting to prevent ‘night soilers’ or the ‘untouchables’ in Mumbai, who are the people in which the government employs to clear the sewage systems, often in very unsanitary and risky situations.

Response: establishment of water and sewage systems

Water Connection in Manila is an initiative funded by the Filipino government in 2010, which aimed at improving the access of clean water to the urban poor. This initiative proved to be successful for the locals, as the poorest 20% paid three times less for water than what they used to pay. Furthermore, to facilitate individual connections, pipes were sometimes laid above ground to lower costs and provide for cheaper maintenance.

After reading this short blog post and in conjunction with your own research – what can you conclude about the responses to the challenges of megacities? Are they effective, ineffective, only sufficient to provide a solution in the short-term or are they sustainable for the longer term?

So many students wait until they feel motivated or have a solid study plan before they begin 🙅‍♀️🙅
But in reality, motivation usually comes after the first action is taken. You don’t need the perfect plan. You just need the first step. 
Start small. Just start.
What does a week at CoWorks look like?
It’s not just one session. It’s not just one weekly touchpoint.
It’s a full system of support designed to build confidence and keep students consistently organised, proactive and motivated across the week.
We still have a few places available for Year 12 students across our campuses. If you’re interested, we’d love to invite you to a free 7-day trial so you can see why students choose CoWorks.

April Study Bootcamp is coming...
The April holidays are a critical time for Year 12 students preparing for the busiest assessment term of the year. While a short break is important, using some of this time to get ahead can make a huge difference for Term 2.
At Bootcamp, students will:
✅ Build essays for upcoming texts and modules
🎯 Practice exam-style responses for completed topics
💡 Strengthen readiness for Term 2 assessments
For Year 11 students, one third of the year is already complete. With only two terms until the HSC year begins, this is the perfect time to consolidate preliminary topics and build strong foundations.
Across the 4-hour structured session each day, students tackle English and other key “frog” subjects to ensure meaningful progress before the term begins.
