Primary Sector Paradox of the Global South: Economic Drivers and Challenges
The economies of many countries in the Global South are heavily dependent on the primary sector, which includes agriculture, mining, and resource extraction. These sectors often form the backbone of their export earnings and GDP. The Global South, comprising developing countries in Africa, Asia, and Latin America, has traditionally relied heavily on the primary sector for economic growth and development.
According to World Bank data, agriculture alone accounts for over 25% of GDP in many low-income countries, particularly sub-Saharan Africa (World Bank, 2022). The United Nations Conference on Trade and Development (UNCTAD) reports that in 2020, agricultural raw materials and food comprised around 10% of total merchandise exports from developing countries. Mining and fuel exports are also significant, making up over 20% of the same year’s merchandise exports from developing countries (UNCTAD, 2021).
Several factors have contributed to the primary sector focus in the Global South. Many developing countries have a comparative advantage in primary commodities due to abundant natural resources and low labour costs. The Heckscher-Ohlin model of international trade suggests that countries will export goods that intensively use their relatively abundant factors of production (Krugman et al., 2018). Additionally, colonial legacies and unequal terms of trade have often locked developing countries into primary commodity dependence (Frank, 1966).
However, reliance on the primary sector has also posed significant challenges for the Global South. Primary commodity prices are notoriously volatile, leading to boom-bust cycles and macroeconomic instability. The Prebisch-Singer hypothesis argues that the terms of trade for primary commodities tend to deteriorate over time relative to manufactured goods, leading to a transfer of wealth from the periphery to the core (Prebisch, 1950; Singer, 1950). Moreover, the primary sector often has weak forward and backward linkages to the rest of the economy, limiting its potential for job creation and technological spillovers (Hirschman, 1958).
The environmental and social costs of primary sector dependence can also be high. Extractive industries like mining and oil drilling are associated with pollution, deforestation, and the displacement of local communities (Bebbington et al., 2008). Agricultural expansion, particularly for cash crops, has also led to deforestation and biodiversity loss in many regions.
Despite these challenges, the primary sector remains vital to many Global South economies. However, there is growing recognition of the need for economic diversification and value addition. The United Nations’ 2030 Agenda for Sustainable Development emphasises sustainable agriculture, responsible resource management, and inclusive growth (United Nations, 2015).
Successful primary sector-led development will require strategic policies and investments. Strengthening linkages between the primary sector and the rest of the economy through local content requirements and processing industries can help create jobs and foster industrialisation. Investing in agricultural research and extension, rural infrastructure, and smallholder support can boost productivity and food security. Implementing environmental and social safeguards can help mitigate the negative impacts of extractive industries.
In conclusion, while the primary sector has been a key driver of growth for many countries in the Global South, it has also posed significant challenges and limitations. Moving forward, a more diversified and sustainable approach is needed to harness the potential of the primary sector while promoting industrialisation, value addition, and inclusive development. With the right policies and investments, countries in the Global South can build more resilient and prosperous economies for the future.
