Pollution from manufacturing industries relocating to less developed countries

The global shift of manufacturing industries from high-income countries (HICs) to low-income countries (LICs) and newly industrialised countries (NICs) has led to significant environmental challenges. HICs often place their polluting industries in LICs to take advantage of weaker regulations, resulting in severe pollution of air, water, and soil, alongside health risks for local populations.

Factors contributing to pollution in LICs and NICs

• Weaker environmental laws - LICs and NICs often have less stringent regulations compared to HICs, allowing industries to emit higher levels of pollutants without penalty.
• Limited enforcement - Even where environmental laws exist, enforcement is often inadequate due to underdeveloped governance systems.
• Economic dependence - Many LICs rely on the economic benefits of hosting polluting industries, prioritising jobs and investment over environmental protection.
• Export of waste - HICs exploit these less-regulated environments to dispose of hazardous waste, further exacerbating pollution.
• Historical disasters - A tragic example is the 1984 Bhopal gas leak in India, where a pesticide plant owned by an American company released toxic gas, causing thousands of deaths and long-term health issues.

Maquiladora development in Mexico and its environmental impact

In Mexico, the maquiladora industry consists of foreign-owned factories, primarily along the border with the United States, where local workers assemble imported parts for export. This industry has grown significantly, bringing economic benefits but also environmental concerns.

Growth and scale of maquiladoras

• Rapid expansion - From the late 1980s to the mid-2000s, the number of maquiladora factories in Mexico grew from under 1,000 to nearly 2,700.
• Employment figures - By the mid-2000s, these factories employed approximately 1.2 million workers.
• Export value - Combined exports from maquiladoras reached over $95 billion (adjusted for inflation) by the mid-2000s.
• Key locations - Major maquiladora hubs include Ciudad Juárez with around 242,600 employees, Tijuana with 177,000, and Reynosa-Rio Bravo with around 100,800.

Attractions for foreign companies

• Low labour costs - Wages in Mexico are significantly lower than in the USA, reducing production expenses.
• Relaxed regulations - Environmental laws are less strict, allowing companies to operate with fewer constraints.
• Proximity to markets - Located near the US border, maquiladoras provide easy access to American markets.

Environmental and health concerns

• Illegal waste dumping - Despite laws requiring hazardous waste to be returned to the USA, illegal dumping in Mexico is widespread, polluting local environments.
• Air pollution impact - Studies in border regions like Paso del Norte show that particulate emissions from maquiladoras contribute to respiratory health issues among residents.
• Other pollution sources - While maquiladoras are significant polluters, unpaved roads, vehicles, and brick kilns were found to be larger sources of particulate emissions in these areas.

Environmental consequences of global agribusiness and intensive farming

The globalisation of food production through agribusiness has transformed farming into a large-scale, intensive operation. While this has increased food output, it has also caused substantial environmental damage due to high-input, high-output methods.

Characteristics of agro-industrialisation

• Intensive methods - Modern farming relies on heavy use of agro-chemicals, machinery, and technology to boost efficiency and yields.
• Increased productivity - In HICs, wheat yields have risen dramatically from around 2.6 tonnes per hectare in the 1960s to over 8 tonnes per hectare today due to fertilisers and pesticides.
• Resource consumption - Farming is a major user of energy and water, contributing to resource depletion.

Environmental impacts of intensive farming

• Greenhouse gas emissions - Livestock farming alone contributes significantly to emissions, with methane and nitrous oxide from agriculture making up a large share of anthropogenic emissions.
• Water pollution - Run-off from pesticides and fertilisers contaminates water sources, costing millions annually to clean up (e.g., up to $200 million per year in the UK for water treatment).
• Air pollution - Agricultural activities release pollutants, with associated costs in the UK exceeding $1.1 billion yearly.
• Land degradation - Intensive methods lead to soil erosion and loss of fertility, damaging long-term agricultural potential.
• Biodiversity loss - Large-scale farming reduces habitats for wildlife, threatening species diversity.

Food miles and global transport

Global food transport significantly increases carbon footprints. For instance, a typical UK Christmas dinner's ingredients may travel more than 38,000 kilometres, with items like poultry from Thailand covering nearly 17,000 kilometres.

Water usage in food production

Land grabs and their impact on local populations

Land grabs involve foreign countries or multinational corporations acquiring vast areas of farmland in LICs, often displacing local communities. This modern phenomenon differs from historical colonial land acquisitions in scale and purpose.

Scale and key players in land grabs

• Massive deals - Recent land acquisitions are enormous, with deals in Sudan involving South Korea for 690,000 hectares and the UAE for 400,000 hectares.
• Global transactions - Since 2006, between 15 and 20 million hectares of farmland in LICs have been involved in foreign deals worth $20-$30 billion.
• Major investors - Countries like the USA (2.2 million hectares), China (1.6 million hectares), and the UAE (1.3 million hectares) are key players.
• Target countries - Sudan (1.8 million hectares), South Sudan (1.7 million hectares), and Ghana (1.3 million hectares) are among the most affected.
• Projected output - Developed land could produce 30-40 million tonnes of cereals annually, a significant portion of the global trade of roughly 220 million tonnes.

Consequences for local populations

• Reduced land access - Indigenous and national populations lose farmland to foreign entities, threatening food security.
• Economic disparity - Investor countries typically have a GDP per capita four times higher than target countries, highlighting global inequalities.
• Social disruption - Displacement of local farmers and communities often leads to conflict and loss of livelihoods.

Water issues and virtual water exports in global farming

Global farming, particularly in water-scarce regions, has led to significant water management challenges. The concept of virtual water—water embedded in exported goods—illustrates how water resources are transferred internationally through trade.

Case study: Water problems in Kenya's flower industry

• Location - Around Lake Naivasha and Mount Kenya, large flower farms owned by British and European companies supply UK supermarkets.
• Water overuse - These farms are accused of extracting excessive water, with the 12 largest firms potentially using as much as 25% of water normally available to over 100,000 small-scale farmers.
• Virtual water export - Flowers, being 90% water, effectively export Kenya's scarce water resources to wetter regions like Europe.
• Pollution concerns - Pesticide run-off from farms pollutes local water sources, harming ecosystems and communities.
• Competition for resources - Flower companies, employing around 55,000 workers, compete directly with nomadic and small-scale farmers for water, often paying the same rates despite their larger usage.
• Economic vulnerability - Disruptions like the 2010 Eyjafjallajökull volcanic eruption in Iceland halted flights, costing Kenya's horticultural industry around $3 million daily in lost exports, with $8 million-worth of flowers destroyed.

Broader implications of water usage

• Environmental strain - Intensive farming exacerbates water scarcity in already dry regions like Kenya, one of the world's driest countries.
• Hidden costs of food miles - Beyond transport emissions, food production impacts include biodiversity loss, eutrophication, and reduced water quality, showing that local sourcing isn't always the most environmentally friendly option.
