MYP Individuals & Societies Social Challenges Notes

How Do Social Challenges Emerge In Urban Systems?

1. Social challenges in cities usually come from the same basic mismatch: urban populations can grow faster than housing, jobs, and public services.
2. When that happens, cities tend to see predictable patterns:
   1. Housing stress: overcrowding, rising rents, informal settlements.
   2. Service gaps: unequal access to clean water, sanitation, healthcare, and schooling.
   3. Job insecurity: informal work and unemployment, especially for recent migrants.
   4. Segregation and inequality: wealth and poverty cluster in different neighbourhoods, creating unequal life chances.

Why Does Rapid Urban Growth Increase Social Pressure?

1. Rapid urban growth increases demand for housing, services, and infrastructure faster than cities can expand them.
2. This mismatch produces overcrowding, particularly in low-income and informal areas.
3. Overcrowding matters because urban systems scale poorly under density stress.
4. Waste collection, sewage treatment, and water supply are designed for a certain number of users.
5. When population density rises sharply:
   1. Waste accumulates faster than it can be collected,
   2. Drainage systems block more frequently,
   3. Shared sanitation facilities become unsafe.
6. These conditions increase the spread of waterborne disease, reduce productivity through illness, and place long-term pressure on healthcare systems.

How Does Inequality Shape Social Outcomes In Cities?

1. Social challenges are shaped not just by growth, but by who is exposed to risk.
2. Lower-income communities are more likely to:
   1. Live near major roads, ports, or industrial zones,
   2. Experience higher air and noise pollution,
   3. Have limited access to healthcare and green space.
3. Wealthier neighbourhoods, by contrast, benefit from:
   1. Zoning protections,
   2. Cleaner environments,
   3. Stronger political influence
4. This shows that environmental inequality translates directly into unequal health and life outcomes, reinforcing social divides.

How Do Environmental Problems Become Social Problems?

1. Environmental challenges affect people through health, safety, and economic stability.
2. Air pollution increases respiratory illness, leading to missed work and school days.
3. Flooding damages homes and infrastructure, forcing displacement and income loss.
4. Waste accumulation increases disease risk, raising healthcare costs.

Why Are Some Social Groups More Vulnerable Than Others?

1. Social vulnerability determines who absorbs environmental risk when systems fail.
2. Groups often at higher risk include:
   1. Migrants,
   2. Informal workers,
   3. The elderly,
   4. Children.

Example

• In cities such as Lagos, many migrant and informal workers live in low-lying or poorly serviced areas.
• Around 60–70% of Lagos’s population lives in informal settlements, many located on flood-prone land or reclaimed wetlands.
• These areas often lack reliable sanitation and drainage, contributing to frequent flooding and higher exposure to waterborne diseases such as cholera.
• Limited income and insecure housing also reduce residents’ ability to relocate, trapping them in high-risk environments.

How Do Social Challenges Reinforce Environmental Problems?

1. Social challenges also make environmental management harder:
   1. Poverty limits access to cleaner fuels, housing, and transport.
   2. Informal settlements are difficult to connect to sewage, waste collection, and drainage networks.
   3. Distrust of authorities reduces cooperation with environmental policies.

Why Are Social Challenges Difficult To Resolve Quickly?

1. Urban social challenges persist because solutions are slow and costly:
   1. Upgrading housing and sanitation requires major investment.
   2. Redevelopment and relocation often face political and community resistance.
   3. Informal settlements frequently lie outside formal planning systems.
2. Meanwhile, environmental pressures such as pollution, flooding, and heat stress continue to intensify.
3. This creates a timing gap:
   1. Social reforms take years,
   2. Environmental risks grow continuously.
