Global trade: patterns, impacts, case studies

Trade, Aid & Tourism – Global Trade: Patterns, Impacts & Case Studies (Cambridge 9696 – Paper 4)

1. Overview & Key Geographical Concepts

Trade, development aid and tourism are inter‑linked systems that operate across a hierarchy of scales – from a local port‑city to a global supply chain. Over recent decades they have shown marked change‑over‑time (e.g., the rise of China as a manufacturing hub, the rapid growth of low‑cost tourism in Southeast Asia). Their spatial distribution illustrates clear spatial variation (core‑semi‑peripheral‑peripheral patterns). Analysing these topics requires recognising cause‑and‑effect relationships (e.g., comparative advantage → export growth → urbanisation) and the environmental interactions they generate. The themes also raise questions of diversity & equality – why some regions benefit more than others and how policy can address imbalances.

2. Trade

2.1 Core Trade Concepts & Terminology (AO1)

• Balance of Payments (BoP): Record of a country’s transactions – current account (goods & services) + capital/financial account.
• Terms of Trade (ToT): Ratio of export prices to import prices; improves when export prices rise relative to import prices.
• Tariffs, Quotas & Non‑tariff barriers (NTBs): Protectionist tools that raise the cost of imports.
• Free Trade Agreements (FTAs) & Trade Blocs: EU, USMCA, ASEAN, MERCOSUR – reduce or remove barriers among members.
• Import Substitution Industrialisation (ISI): Policy to replace imports with domestic production (historically used in Latin America).
• Export‑Promotion Strategies: SEZs, export‑processing zones (EPZs), subsidies, tax incentives.
• Trade Liberalisation: Reducing tariffs/NTBs to encourage market‑driven trade (e.g., WTO negotiations).

2.2 Trade Theories (AO1)

1. Absolute Advantage – a country can produce a good more efficiently than another.
2. Comparative Advantage – a country specialises in goods with the lowest opportunity cost, benefiting all trading partners.
3. Heckscher‑Ohlin (Factor‑Endowment) Model – trade is driven by differences in labour, capital and land endowments.
4. New Trade Theory – economies of scale and network effects lead to concentration of industries (e.g., electronics in East Asia).
5. Global Value Chains (GVCs) – production is fragmented across borders; each country adds a specific “stage” (e.g., design in the US, assembly in China).

2.3 Major Exporters & Importers (2024 – UNCTAD data) (AO1)

Rank	Country	Export value (US$ bn)	Import value (US$ bn)	Trade balance (US$ bn)
1	China	3,620	2,340	+1,280
2	United States	1,720	2,960	–1,240
3	Germany	1,580	1,250	+330
4	Japan	740	680	+60
5	South Korea	590	480	+110

Note: figures are rounded; latest UNCTAD “Trade Statistics Review 2024” provides annual updates.

2.4 Trade Routes & Corridors (spatial variation & scale) (AO2)

• Maritime Silk Road: East Asia ↔ South‑Asia ↔ Middle East ↔ Europe – dominates container traffic for electronics, textiles and machinery.
• Trans‑Atlantic Route: North America ↔ Europe – key for oil, grains, automobiles and high‑value services.
• Pan‑African Corridors: e.g., North–South Corridor (Dar es Salaam ↔ Johannesburg) – vital for land‑locked states.
• China‑Pakistan Economic Corridor (CPEC): Rail & road linking western China to the Pakistani port of Gwadar, facilitating energy and mineral exports.
• Inland Waterways: Rhine–Danube (Europe) and the Mississippi (USA) – support bulk commodities such as coal, grain and timber.

2.5 Trade Blocs & FTAs – Regional Integration (AO2)

Bloc / Agreement	Members (selected)	Key Features
European Union (EU)	27 states (e.g., Germany, France, Italy)	Customs union, single market, common external tariff, structural funds for less‑developed regions.
ASEAN Free Trade Area (AFTA)	10 Southeast Asian nations (e.g., Vietnam, Thailand)	Tariff reductions, “ASEAN Economic Community” for services & investment.
USMCA (formerly NAFTA)	USA, Canada, Mexico	Zero‑tariff for most goods, stricter rules of origin, updated labour & environmental chapters.
MERCOSUR	Argentina, Brazil, Paraguay, Uruguay (plus associate members)	Customs union, common external tariff, focus on agricultural & industrial goods.

2.6 Impacts of Global Trade (AO2)

Economic Impacts

• GDP Growth: Export‑led growth in East Asia (China, Vietnam) has lifted per‑capita incomes.
• Employment Shifts: Movement from agriculture to manufacturing & services; emergence of “factory towns” (e.g., Shenzhen).
• Terms of Trade: Commodity exporters (Nigeria, Brazil) are vulnerable to price volatility; manufacturers (Germany) enjoy relatively stable ToT.
• Trade Deficits & Surpluses: Persistent US deficit financed by capital inflows; Chinese surplus creates large foreign‑exchange reserves.
• Industrial Upgrading: Participation in GVCs encourages technology transfer (e.g., electronics assembly → design capability in Vietnam).

Social Impacts

• Urbanisation: Port cities (Shanghai, Rotterdam) expand rapidly, creating housing pressure and informal settlements.
• Income Inequality: Skilled workers in export sectors command higher wages; low‑skill labour often faces precarious contracts.
• Cultural Exchange: Global brands, food and media spread along trade routes, influencing lifestyles.
• Labour Standards: Export‑processing zones can have poor health & safety conditions – a challenge for equitable development.

Environmental Impacts

• Carbon Emissions: Shipping (≈90 % of world trade by volume) contributes ~3 % of global CO₂.
• Land‑use Change: Export‑oriented agriculture – soybeans in Brazil, palm oil in Indonesia – drives deforestation, soil degradation and water stress.
• Pollution & Waste: Port cities experience air and water pollution from cargo handling and fuel combustion.
• Resource Depletion: Over‑exploitation of fisheries for export (e.g., West African tuna).

2.7 Case Studies (AO2 & AO3)

China – Export‑Driven Growth (Core)

• Special Economic Zones (SEZs) – tax holidays, relaxed labour regulations, dedicated infrastructure.
• Deep integration into GVCs – electronics, textiles, machinery.
• Outcomes: rapid urbanisation of coastal megacities, GDP per capita rise, but increasing air‑pollution and water quality issues.
• Evaluation: While SEZs have accelerated growth, they have also created regional disparities (coastal vs. interior) and environmental challenges that require stronger regulation.

Nigeria – Commodity Dependence (Peripheral)

• Oil accounts for >90 % of export earnings; limited diversification.
• Vulnerability to global oil‑price swings → recurrent BoP crises.
• Environmental damage from oil spills and gas flaring.
• Evaluation: Heavy reliance on a single export commodity hampers sustainable development; diversification strategies (e.g., agro‑processing) remain politically and financially constrained.

Brazil – Agricultural Exporter (Semi‑Peripheral)

• World’s largest exporter of soybeans, beef and coffee.
• Agribusiness expansion drives deforestation in the Amazon and threatens biodiversity.
• Export earnings fund infrastructure, yet stark regional inequality persists (industrial south vs. rural north).
• Evaluation: Export revenues support macro‑economic stability, but environmental costs and social inequities raise questions about long‑term sustainability.

Vietnam – Garment & Electronics Manufacturing (Semi‑Peripheral)

• Low‑cost labour and FTAs (EU‑Vietnam, CPTPP) attract FDI.
• Shift from rice‑based agriculture to export‑oriented factories; massive rural‑to‑urban migration to Ho Chi Minh City.
• Positive GDP growth, yet rising air pollution and housing shortages.
• Evaluation: Vietnam’s export model has lifted living standards, but reliance on low‑wage labour may limit future value‑addition unless up‑skilling policies are pursued.

European Union – Regional Trade Integration (Core/Regional)

• Single market removes internal tariffs; harmonised standards facilitate intra‑EU trade.
• Structural funds support less‑developed regions (e.g., Eastern Europe) – reducing intra‑regional disparities.
• Challenges: Brexit, divergent fiscal policies, and the need to “green” transport and logistics.
• Evaluation: The EU demonstrates how deep integration can boost trade and cohesion, but political fragmentation and climate targets test the bloc’s resilience.

3. Aid – Types, Links to Trade & Geographical Concepts

3.1 Types of Development Aid (AO1)

• Official Development Assistance (ODA): Grants & concessional loans from governments.
• Bilateral Aid: Direct from one donor country to a recipient (e.g., UK’s Department for International Development).
• Multilateral Aid: Delivered through organisations such as the World Bank, UNDP, African Development Bank.
• Trade‑Related Aid: Infrastructure for ports, roads, customs modernisation; capacity‑building for export promotion.
• Remittances: Private transfers from migrants – often exceed ODA in low‑income countries.

3.2 Major Donors (2023‑24 data) (AO1)

Donor	Aid Disbursed (US$ bn)	Key Sectors
United States	34.5	Health, education, governance
United Kingdom	12.1	Infrastructure, climate resilience
Germany	9.8	Renewable energy, vocational training
Japan	8.4	Disaster risk reduction, transport
European Union	15.2	Regional development, agriculture, research

3.3 How Aid Interacts with Trade (Cause‑and‑Effect) (AO2)

• Improved transport infrastructure lowers export costs – e.g., road upgrades in Kenya have boosted horticultural exports to Europe.
• Capacity‑building programmes help small‑scale producers meet international standards, expanding market access.
• Potential negatives: “Aid dependency” and “Dutch disease” – large inflows can appreciate the local currency, reducing export competitiveness.

3.4 Impacts of Aid (AO2)

• Economic: Stimulates growth through infrastructure, but impact varies with absorptive capacity.
• Social: Improves health and education outcomes; gender‑responsive budgeting can reduce inequality.
• Environmental: Green aid (e.g., renewable‑energy projects) can mitigate climate impacts, but poorly designed projects may cause displacement.

3.5 Case Study – Kenya’s Horticultural Export Corridor (AO3)

• Background: ODA funded the construction of the “Northern Corridor” road network linking Nairobi to the port of Mombasa.
• Outcome: Transport time for fresh produce fell from 7 days to 2 days, allowing higher‑value exports to the EU.
• Evaluation: While trade volumes increased, benefits were concentrated among large growers; smallholders struggled to meet phytosanitary standards, highlighting the need for complementary capacity‑building.

4. Tourism – Service Export, Types & Impacts

4.1 Types of Tourism (AO1)

• Mass Tourism: Large‑scale, often package‑based (e.g., Mediterranean beach resorts).
• Eco‑tourism: Low‑impact travel focused on natural environments and conservation.
• Cultural & Heritage Tourism: Visits to historic sites, festivals, museums.
• Medical & Wellness Tourism: Travel for health treatments or spa experiences.
• Adventure & Sports Tourism: Activities such as trekking, surfing, ski‑resorts.

4.2 Economic & Social Impacts (AO2)

• Foreign Exchange Earnings: Tourism accounts for ~8 % of global GDP (UNWTO 2024).
• Employment: Direct (hotels, airlines) and indirect (food production, crafts) jobs; often seasonal and low‑paid.
• Infrastructure Development: Airports, roads, and urban regeneration funded by tourism revenue.
• Cultural Exchange & Identity: Promotion of local heritage, but risk of “commodification” of culture.
• Social Challenges: Over‑tourism, housing pressure for locals, gendered employment patterns.

4.3 Environmental Impacts (AO2)

• Carbon Footprint: Air travel contributes ~2 % of global CO₂ emissions.
• Resource Strain: Water use in resorts, waste generation, and habitat disturbance.
• Conservation Benefits: Eco‑tourism can fund protected‑area management when well‑regulated.

4.4 Case Study – Barcelona (Mass & Cultural Tourism) (AO3)

• Growth: International arrivals rose from 4 million (2000) to >12 million (2023).
• Impacts: Boost to service‑sector GDP and employment; however, housing prices doubled, prompting resident protests.
• Management Response: Introduction of a tourist‑tax, limits on short‑term rentals, and investment in alternative attractions (e.g., Montjuïc cultural venues).
• Evaluation: Revenue gains are evident, but social equity concerns persist; policy effectiveness depends on enforcement and community involvement.

5. Climate‑Change Impacts & Governance (Paper 4 requirement)

5.1 Physical Impacts (AO2)

• Sea‑level rise: Threatens low‑lying coastal trade hubs (e.g., Rotterdam, Lagos) and tourism beaches.
• Extreme weather events: Hurricanes, floods and heatwaves disrupt supply chains, damage infrastructure and shorten tourism seasons.
• Ecosystem shifts: Coral‑reef bleaching reduces marine‑tourism appeal; changing rainfall patterns affect agricultural export volumes.

5.2 Socio‑economic Impacts (AO2)

• Migration: Climate‑induced displacement creates new labour flows and remittance patterns.
• Food security: Crop‑yield volatility (e.g., wheat in the Black Sea region) influences terms of trade and import dependence.
• Tourism seasonality: Shorter winter ski seasons in the Alps; longer beach seasons in the Caribbean – both affect revenue predictability.

5.3 Governance Mechanisms (AO2)

• International: UNFCCC, Paris Agreement (Nationally Determined Contributions – NDCs), IPCC assessments.
• Regional: EU Emissions Trading System (ETS), ASEAN Climate Change Initiative.
• National: Adaptation plans (e.g., Bangladesh Climate Change Strategy and Action Plan 2021‑2030), climate‑resilient infrastructure investment.

5.4 Case Study – Bangladesh Flood‑Risk Management (AO3)

• Vulnerability: 20 % of the population lives below 1 m elevation; annual monsoon floods threaten rice exports.
• Adaptation measures: Construction of embankments, community‑based early‑warning systems, and “climate‑smart” rice varieties.
• Governance: Coordination between the Ministry of Disaster Management, World Bank‑funded “Bangladesh Delta Plan 2100”, and NGOs.
• Evaluation: Flood defenses have reduced loss of life, yet maintenance gaps and rapid urbanisation in flood‑prone areas limit long‑term effectiveness.

---

6. Environmental Issues & Management (Paper 4 requirement)

6.1 Major Global Environmental Issues (AO1)

• Deforestation: Driven by agricultural expansion (soy, palm oil) – 10 % of global forest loss per year.
• Water Scarcity: Over‑extraction for irrigation and industry; 1.2 billion people face high water stress.
• Biodiversity Loss: Species extinction rates ~1000× background levels; impacts ecosystem services that underpin trade (e.g., pollination).
• Climate Change: Interacts with all other issues, amplifying risks to trade routes, aid needs and tourism.

6.2 Management Approaches (AO2)

• Hard engineering: Dams, sea walls, flood‑gates – effective for immediate risk reduction but can cause downstream impacts.
• Soft / ecosystem‑based management: Reforestation, mangrove restoration, sustainable agro‑forestry – provide long‑term resilience and co‑benefits.
• Policy instruments: Payments for ecosystem services (PES), carbon pricing, trade‑related environmental standards (e.g., EU Timber Regulation).
• International agreements: Convention on Biological Diversity (CBD), UN Sustainable Development Goals (SDG 15 – Life on Land).

6.3 Contrasting Country Case Studies (AO3)

Amazon Deforestation – Brazil (Negative Example)

• Drivers: Soy cultivation, cattle ranching, illegal logging.
• Impacts: Loss of carbon sink, reduced biodiversity, conflicts with indigenous peoples.
• Management response: “Soy Moratorium” (voluntary agreement with traders) and increased satellite monitoring.
• Evaluation: Deforestation rates fell 30 % (2004‑2012) but rose again after 2019 due to policy roll‑backs, showing the fragility of voluntary schemes.

Costa Rica – Reforestation & Eco‑tourism (Positive Example)

• Policy: Payments for Environmental Services (PES) launched in 1997 – landowners receive subsidies for forest restoration.
• Outcomes: Forest cover increased from 21 % (1980) to >52 % (2022); eco‑tourism now contributes ~5 % of GDP.
• Evaluation: PES demonstrates how market‑based incentives can align conservation with economic benefits, though long‑term funding sustainability remains a concern.

7. Disease & Geography (Paper 4 requirement)

7.1 How Geography Shapes Disease Spread (AO2)

• Vectors & Environment: Mosquito‑borne diseases (malaria, dengue) thrive in warm, wet climates and are linked to land‑use change (e.g., irrigation).
• Human Mobility: Air travel and trade routes accelerate global transmission – COVID‑19 spread to >200 countries within three months of the first case.
• Urbanisation: High‑density settlements facilitate person‑to‑person transmission; informal settlements often lack sanitation.
• Climate Change: Expanding suitable habitats for vectors (e.g., Aedes aegypti moving into temperate zones).

7.2 Case Study – COVID‑19 Pandemic (AO3)

• Geographic pathways: Initial spread from Wuhan via international air hubs (e.g., Dubai, London) to global hotspots.
• Impacts on trade & tourism: 2020 global merchandise trade fell 5.3 %; international tourism arrivals dropped 74 % (UNWTO).
• Control strategies: Border closures, travel bans, test‑trace‑isolate programmes, vaccine rollout.
• Evaluation: Early travel restrictions slowed seeding in some regions but had limited effect once community transmission was established; economic costs were massive, highlighting the need for balanced, evidence‑based policies.

7.3 Case Study – Malaria in Sub‑Saharan Africa (AO3)

• Geographic drivers: Warm temperatures, seasonal rains, and extensive river networks create breeding sites.
• Interventions: Insecticide‑treated nets (ITNs), indoor residual spraying, artemisinin‑based combination therapies (ACTs).
• Outcomes: WHO reported a 29 % reduction in malaria deaths (2000‑2020), but progress stalled after 2015.
• Evaluation: Success depends on sustained funding, resistance management (insecticide and drug resistance), and integration with broader health‑system strengthening.
