AQA GCSE Geography (8035) — Challenges in the human environment
You probably know Hollywood and Bollywood, but did you know Nigeria's film industry, 'Nollywood', produces over 2,000 films a year, making it the second-largest in the world? This is just one example of Nigeria's growing global influence. Nigeria is located in West Africa, sitting just north of the Equator. It has critical maritime access to the Atlantic Ocean via the Gulf of Guinea on its southern coast. It shares land borders with Benin to the west, Niger to the north, Chad to the northeast (bordering Lake Chad), and Cameroon to the east.
Nigeria is classified as a Newly Emerging Economy (NEE) and holds immense regional and global importance. Globally, it was the world's 21st largest economy in 2014 and is the 12th largest oil producer, pumping around 2 million barrels of high-quality, 'sweet' oil per day (2.7% of the global supply). It also has the 7th largest population globally (over 200 million) and is a major contributor to UN peacekeeping.
Regionally, Nigeria is an economic powerhouse. It boasts the highest GDP in Africa and the largest farm output, holding the continent's highest number of cattle. Lagos acts as a global 'world city' and the primary financial hub for Western Africa. Nigeria does not operate in isolation; it is a key member of international organisations like OPEC (coordinating oil policies) and ECOWAS (a West African trading group promoting collective self-sufficiency).
Understanding a country's historical timeline explains why its economic development is happening now, rather than decades ago. Nigeria gained independence from the UK in 1960 but suffered a civil war from 1967 to 1970. It was not until 1999 that Nigeria transitioned to a stable democracy. This political stability was the crucial turning point that finally attracted widespread Foreign Direct Investment (FDI).
Socially, Nigeria is a highly diverse, multi-ethnic nation with over 500 languages. It is dominated by three main groups: the Hausa in the north, the Yoruba in the southwest, and the Igbo in the southeast. There is a distinct 'North-South divide' in both wealth and religion, with the population roughly split between Islam in the north (50-54%) and Christianity in the south (40-48%). Inequality between the urbanised south and the rural north has fuelled social conflict, notably the rise of , an extremist group in the north-east that has severely hindered local development.
Despite its wealth, Nigeria's Human Development Index (HDI) rank is low (approximately 158/188), and its literacy rate sits at just 65%. However, rapid urbanisation means nearly 50% of the population now lives in cities, driving cultural exports like music (a US$73 million industry) and international sporting success.
If you travel from the south of Nigeria to the north, you walk from dense, humid tropical rainforests into dry, dusty scrubland. Nigeria's environment follows strict latitude-based 'bands'. The south experiences a tropical climate with high rainfall (over 2,500mm), supporting mangrove swamps and tree crops like cocoa and rubber. The central region consists of savanna grasslands, while the north enters the Sahel, a semi-arid zone with low rainfall (500-1,000mm) suited for growing groundnuts and nomadic cattle grazing. The central Jos Plateau is an exception; its high altitude makes it cooler and wetter.
Rapid economic development has caused severe environmental degradation. In the oil-rich Niger Delta in the south, over 9 million barrels of oil have been spilled over 50 years, with disasters like the Bodo oil spill (2008-2009) destroying 20 sq km of swamps. Furthermore, Nigeria has the world's highest rate of primary forest loss, losing 3.7% of its forest cover annually to logging and agriculture.
In the north, climate change and overgrazing are causing Desertification, with Nigeria losing approximately 0.35% of its total land area to the desert every year. In urban centres like Lagos, industrial waste pollutes waterways, and average PM2.5 air pollution levels frequently reach 'Unhealthy' limits that are two to five times higher than WHO recommendations.
Why does opening a single factory change an entire town's wealth? As an NEE, Nigeria is transitioning away from farming towards a more varied economy. Between 1999 and 2024, the proportion of people employed in the Primary sector (agriculture) plummeted from 70% to around 30.1% due to farm mechanisation. Over the same period, the Secondary sector (manufacturing) and the Tertiary sector (services) grew significantly. Today, services contribute roughly 52-54% of Nigeria's GDP, dominating the economy.
Nigeria is also developing a cutting-edge Quaternary sector. The Information and Communication Technology (ICT) industry now contributes approximately 16.35% to the GDP. With over 221 million active mobile lines, Nigeria is Africa's largest ICT market, and tech hubs like Lagos's 'Yabacon Valley' attract global venture capital.
However, the economy is not perfectly secure. Approximately 92.7% of the workforce is stuck in the Informal sector. These jobs are not taxed or monitored by the government, leading to high Underemployment (around 10.6%). Furthermore, Nigeria does not have a truly Balanced Economy; while employment is spreading out, oil still accounts for 98% of export earnings, making the country highly vulnerable to global oil price crashes.
The growth of manufacturing (like sugar refining and textiles) drives the economy forward through a mechanism called the Multiplier Effect. We can break this down step-by-step using a Transnational Corporation (TNC):
Students often confuse 'regional' and 'global' importance. If a question asks for global importance, do not talk about Nigeria having the highest GDP in Africa; use global stats like being the 12th largest oil producer.
When a question asks you to 'describe the location', you must be specific to get full marks: name the region (West Africa), the body of water it touches (Gulf of Guinea), and at least two bordering countries (e.g., Benin and Cameroon).
Thinking Nigeria has a fully 'balanced' economy. While employment is now split more evenly across primary, secondary, and tertiary sectors, 98% of its export earnings still come from oil, meaning its GDP is highly vulnerable.
In 'Describe' questions about industrial structure, examiners expect you to use data. Quote the shift in primary employment (falling from 70% in 1999 to ~30% today) to prove your point.
