The Relationship Between Deforestation and GDP in the Amazon, Indonesia, and the Congo Basin – July 1995 to the 2020s

The Relationship Between Deforestation and GDP in the Amazon, Indonesia, and the Congo Basin – July 1995 to the 2020s The 1990s – The Paradox of Deforestation and Economic Growth During the 1990s, rapid deforestation occurred in the Brazilian Amazon, Indonesia, and the Congo Basin in Africa. While these regions experienced short-term economic growth through agricultural development and timber exports, hidden behind this growth were environmental costs that were not reflected in GDP. In the Brazilian Amazon, agricultural development and timber exports advanced from the 1970s onward, resulting in the loss of approximately 10,000 square kilometers of forest each year. Consequently, approximately 400 million tons of CO₂ were emitted annually, accelerating global warming. Although environmental issues such as soil degradation and ecosystem collapse began to surface at this point, these impacts were not adequately reflected in GDP. Deforestation in the Amazon was jeopardizing long-term sustainability as the price of short-term economic growth. In Indonesia, palm oil production expanded, leading to rapid deforestation. Slash-and-burn farming in wetlands released greenhouse gases such as CO₂ and methane, causing air pollution that affected neighboring countries. As a result, Indonesia became the world’s third-largest emitter of greenhouse gases, and while environmental costs increased, economic growth driven by palm oil exports was reflected in GDP. Meanwhile, in Africa’s Congo Basin, agricultural development and illegal logging also progressed. The Congo Basin’s forests were considered a “carbon sink,” playing a role in absorbing approximately 88 billion tons of carbon; however, tens of millions of tons of CO₂ were released annually, reducing their carbon absorption capacity. Consequently, the livelihoods of local residents and the ecosystem were severely impacted, and while it was predicted that restoration would require enormous costs, these burdens were not reflected in GDP. The 2000s – Growing Environmental Awareness and the Introduction of New Economic Indicators In the 2000s, some countries began introducing “Green GDP,” which takes into account the impacts of environmental destruction. Costa Rica, in particular, promoted the adoption of "Green GDP," which incorporates environmental costs such as deforestation and water pollution into economic indicators, and saw positive environmental outcomes, including an increase in forest coverage. Ecotourism flourished, and annual tourism revenue grew to the scale of billions of dollars. By incorporating these long-term benefits into GDP, sustainable development was achieved, making it a leading example that influenced other nations. In Japan as well, companies such as Hitachi and Seiko Epson introduced technologies to reduce CFCs and protect the ozone layer, achieving annual reductions of over 10,000 tons of CO₂ equivalent. However, these corporate environmental contributions were not directly reflected in GDP; rather, they were public goods enjoyed by society as a whole, leaving a persistent gap between the environment and the economy. The 2020s – The Reality of Environmental Costs and Global Responses As we entered the 2020s, the importance of the environmental costs of deforestation has grown even more significant, and movements toward sustainability have accelerated worldwide. However, many countries continue to prioritize economic growth over environmental protection, leading to ongoing environmental destruction. In the Amazon region of Brazil, 13,400 square kilometers of forest were lost in 2021, releasing 500 million tons of CO₂ into the atmosphere. The associated costs of climate change mitigation are estimated to reach $100 billion, yet these costs are still not accounted for in GDP. The Brazilian government has indicated a policy of easing logging restrictions on the grounds of economic growth, and deforestation continues to advance; however, international pressure is also intensifying. In Indonesia, revenue from palm oil exports reached approximately $30 billion in 2021, supporting economic growth, but the issue persists that the environmental costs of deforestation are not reflected in GDP. CO₂ emissions from forest fires in 2020 amounted to approximately 700 million tons, and methane emissions from the loss of wetlands are accelerating global warming. In Africa’s Congo Basin, 500,000 hectares of forest are cleared annually, resulting in 60 million tons of CO₂ emissions each year. While illegal logging and mineral extraction continue to accelerate deforestation, and efforts by NGOs and corporations are underway, the long-term environmental costs resulting from the loss of carbon sequestration capacity are not accounted for in GDP. Costa Rica continues to be recognized as a success story in environmental protection through the adoption of Green GDP. In 2022, forest coverage reached 59%, and annual revenue from ecotourism amounted to $5 billion. Investments in environmental conservation are supporting sustainable economic growth, and plans to achieve carbon neutrality by 2050 are underway. In Japan, Hitachi has advanced CO₂ reduction technologies, achieving an annual reduction of 20,000 tons of CO₂. Furthermore, decarbonization is progressing, with Toyota Motor Corporation entering the electric vehicle (EV) market and announcing a policy to phase out the production of gasoline-powered vehicles by 2035. However, the environmental conservation benefits resulting from corporate efforts are not reflected in GDP, and challenges remain on the path to sustainable development. Conclusion Through these historical developments, the contradiction between deforestation and economic growth has become starkly apparent. It has become clear that if deforestation continues without the environmental costs being made explicit, in pursuit of short-term GDP growth, serious long-term consequences—such as global ecosystem destruction and accelerated global warming—will emerge. To achieve sustainable economic development, new economic indicators that take environmental factors into account are necessary, and there is a growing need to evaluate Green GDP and the adoption of environmental technologies by companies.
