Major cities in lower-income or emerging/developing countries face a distinct set of challenges and opportunities due to rapid urbanisation, limited resources, and evolving economic structures. Challenges often include the proliferation of informal settlements (slums) lacking basic infrastructure like sanitation, clean water, and stable housing. This leads to significant health risks, environmental pollution, and social inequality. Traffic congestion, air pollution from vehicle emissions and industrial activity, and inadequate waste management are also common issues. Furthermore, high unemployment rates and the growth of the informal economy can create social instability and limit access to formal employment benefits.

However, these cities also present considerable opportunities. Rapid population growth and a youthful demographic can provide a large and flexible labour force, attracting foreign investment and fostering economic growth. The informal sector, while challenging, can also be a source of entrepreneurship and resilience, providing essential goods and services to urban populations who might otherwise be underserved. Investment in infrastructure projects, such as public transport, communication networks, and housing, can improve living standards and create jobs. Cultural diversity and vibrant community life often thrive in these urban environments. International aid and non-governmental organisations (NGOs) frequently target these cities, offering support for sustainable development projects, health initiatives, and educational programs. Understanding both the difficulties and the potential for development is crucial for addressing the complex realities of these dynamic urban centres.

Rapid urbanisation refers to the swift increase in the proportion of a country's population living in urban areas, often occurring over a relatively short period. This phenomenon is particularly prevalent in Newly Industrialised Countries (NICs) and Less Developed Countries (LDCs). The primary drivers, or 'pull' factors, attracting people to cities include perceived better economic opportunities, such as jobs in factories or services, higher wages, and improved access to amenities such as education, healthcare, and infrastructure like electricity and piped water. Conversely, 'push' factors compel people to leave rural areas, encompassing poverty, lack of jobs, food insecurity due to agricultural challenges (e.g., drought, soil degradation), natural disasters, and conflicts. This rural-to-urban migration, combined with high natural population growth rates within cities, fuels rapid urbanisation.

While urbanisation can bring economic growth, innovation, and cultural diversity, it also precipitates significant challenges, particularly when it occurs too quickly for cities to adapt. Environmental consequences include increased air and water pollution, waste generation, deforestation for urban expansion, and higher energy consumption. Social impacts often manifest as overcrowded housing, leading to the development of informal settlements (slums) with inadequate sanitation and limited access to clean water. Crime rates may rise, and social inequality can become more pronounced. Economic challenges include unemployment or underemployment for new arrivals, strain on public services (transport, schools, hospitals), and the growth of informal economies. Understanding these causes and evaluating the resulting consequences is crucial for sustainable urban planning and development, aiming to mitigate the negative impacts while harnessing the benefits of urban growth.
