Concept of Compact City
High Density Development
The compact city model emphasizes high density development, with buildings closer together and less reliance on cars.
Efficient Land Use
It prioritizes efficient use of land, minimizing urban sprawl and preserving green spaces.
Mixed-Use Development
This model encourages a blend of residential, commercial, and public uses, creating walkable neighborhoods with convenient access to amenities.
Improved Public Transit
Compact cities rely heavily on public transportation, reducing car dependency and promoting sustainable travel modes.
Advantages of Compact City
Reduced Emissions
Less travel leads to lower CO2 emissions. This improves air quality and reduces climate change.
Efficient Land Use
Compact cities minimize sprawl, preserving natural habitats and farmland.
Enhanced Walkability
Shorter distances and pedestrian-friendly design encourage walking and cycling.
Improved Connectivity
Efficient public transportation systems improve accessibility and reduce travel time.
Reduced Sprawl and Land Consumption
Sustainable Land Use
Compact cities promote efficient land use, minimizing the need for sprawling urban development. This reduces the pressure on natural ecosystems and preserves valuable green spaces.
Reduced Infrastructure Costs
Compact development requires less infrastructure, such as roads, utilities, and public transportation, resulting in significant cost savings and reduced environmental impact.
Protection of Biodiversity
By limiting urban sprawl, compact cities help protect habitats and biodiversity. This is essential for maintaining a healthy ecosystem and mitigating climate change.
Efficient Use of Infrastructure
Reduced Transportation Costs
Compact cities allow for more efficient public transportation systems. People live closer to their workplaces and amenities, requiring fewer car trips.
Lower Energy Consumption
Compact development reduces the distance people need to travel, leading to lower fuel consumption and greenhouse gas emissions.
Improved Resource Management
Compact cities require less infrastructure to service the same population, resulting in lower costs for utilities, waste management, and other services.
Reduced Emissions and Energy Use
1
1. Reduced Transportation Demand
Compact cities encourage walking, cycling, and public transport, leading to a significant reduction in car usage.
2
2. Enhanced Energy Efficiency
Higher density living allows for more efficient use of utilities and resources, reducing energy consumption overall.

3. Lower Emissions Footprint
Reduced energy usage leads to lower greenhouse gas emissions, contributing to a more sustainable urban environment.
Increased Walkability and Livability
Pedestrian-Friendly Design
Compact cities often prioritize pedestrian movement. This includes wide sidewalks, crosswalks, and dedicated bike lanes.
Public Spaces and Parks
Green spaces and public squares become focal points for social interaction, encouraging residents to spend time outdoors.
Reduced Dependence on Cars
Compact cities promote walking, cycling, and public transportation, reducing reliance on private vehicles, leading to lower congestion and cleaner air.
Limitations of Compact City Approach
The compact city approach, while offering numerous benefits, also faces several challenges. These limitations are often complex and require careful consideration to ensure a balanced and sustainable urban development.
Limitations of Compact City Approach
High Density and Overcrowding Concerns
High-density living can lead to overcrowding, putting pressure on infrastructure and public spaces. Increased demand for resources like water, sanitation, and transportation can strain the city's capacity, potentially leading to discomfort and reduced quality of life.
Affordability and Gentrification Issues
As compact city approaches often involve redeveloping existing areas, they can lead to gentrification and displacement of lower-income residents. Rising property values and rents may make it increasingly difficult for those who live in these areas to afford staying, potentially exacerbating social and economic inequalities.
Affordability and Gentrification Issues
Rising Housing Costs
Compact city approaches often lead to increased demand for housing in desirable areas, driving up prices and making it challenging for lower-income residents to afford living in the city.
Displacement of Residents
As neighborhoods become more desirable due to compact city initiatives, existing residents may be displaced as property values rise and landlords seek to capitalize on the changes.
Social Equity Concerns
Compact city policies must address affordability and social equity issues to ensure that the benefits of urban densification are shared by all residents, not just the wealthy.
Challenges of Retrofitting Existing Cities
1
Infrastructure Constraints
Existing infrastructure, like roads and utilities, may not be easily adaptable to a denser, more compact urban form.
2
Costly and Time-Consuming
Retrofitting can be significantly more expensive and time-consuming than building from scratch, leading to delays and financial hurdles.
3
Public Resistance
Residents may resist changes to their neighborhoods, especially if they involve disruptions to their lifestyles or property values.
4
Limited Space
Existing cities often lack the physical space needed for expansion, making it challenging to implement a compact city approach.
Forms of Cities in Developing World
Developing countries present diverse urban forms, reflecting historical, economic, and social factors.
Urban landscapes are shaped by rapid population growth, migration, and limited resources. These cities grapple with challenges like informal settlements, unplanned growth, and providing essential services.
Informal Settlements and Slums
Informal settlements, often referred to as slums, are densely populated areas characterized by inadequate housing, lack of basic services, and informal land tenure.
These settlements arise due to rapid urbanization, poverty, and limited access to affordable housing options, often resulting in overcrowded and unsanitary conditions.
Unplanned Urban Growth
Lack of Planning
Rapid population growth and lack of infrastructure development result in informal settlements.
Sprawling Development
Urban areas expand without coordinated planning, leading to inefficient use of resources.
Traffic Congestion
Unsustainable transportation systems contribute to traffic bottlenecks and environmental degradation.
Challenges of Providing Services
Sanitation and Infrastructure
Rapid urbanization in developing countries often outpaces infrastructure development, leading to inadequate sanitation and water supply. Poor infrastructure exacerbates issues like pollution, disease outbreaks, and public health concerns.
Overburdened Services and Resources
The influx of people into developing cities places immense strain on existing public services, such as healthcare, education, and transportation. This leads to overcrowded facilities, long wait times, and limited access to quality services.
Economic Disparities and Unemployment
Rapid urban growth often results in job shortages and economic disparities. Many residents face unemployment, lack of access to education and skills training, and struggle to find decent-paying jobs. This contributes to poverty and inequality.

Sustainable Development Practices
Promoting environmental protection and resource efficiency
Developing cities face unique challenges in improving their living standards. A comprehensive approach is needed to address these challenges. Integrated urban planning is crucial to create efficient and equitable cities. Infrastructure investments are essential to improve public services and transportation. Affordable housing solutions are vital to ensure access to safe and decent living conditions. Community engagement is vital for ensuring local ownership and support for development initiatives. Finally, sustainable development practices are needed to protect the environment and promote long-term sustainability.
Integrated Planning and Upgrading Initiatives
Community Engagement
Involving residents in planning and upgrading is crucial. Local knowledge and needs should be considered.
Multi-Sectoral Collaboration
Coordination between different sectors, such as housing, infrastructure, and social services, is necessary for success.
Sustainable Infrastructure
Investing in green spaces, efficient transportation systems, and renewable energy can create more resilient and livable cities.
Affordable Housing
Developing affordable housing options for low-income residents is essential for equitable urban development.
