Peru's Economy Suffers From Pollution's Heavy Hand

Peru is facing a range of environmental issues, from water and air pollution to soil erosion and deforestation, which are having a significant impact on its economy. The country's environmental problems are caused by a combination of industrial and vehicle emissions, sewage, and oil-related waste, as well as population growth and unregulated industries such as mining, oil, and natural gas production. These issues are detrimental to Peru's economy, causing premature deaths, health issues, and a decline in biodiversity. The Peruvian government has recognised the urgency of the situation and is taking steps to address these challenges, including developing regulations and laws to reduce pollution and deforestation.

Air pollution in Lima and other cities

Peru is home to over 30 million people and is increasingly vulnerable to the impacts of climate change, from sea level rise to extreme weather events and agricultural depletion. Air pollution is a significant environmental health risk, causing over 9,000 premature deaths per year.

Air pollution in Peru is particularly bad in urban centres such as Lima, which has some of the highest levels of air pollution in Latin America. By the early 2000s, air pollution in Lima and other Peruvian cities was so severe that it caused thousands of premature deaths every year. The air quality in Lima was worse than in other large Latin American cities such as Mexico City or Sao Paulo. In 2006, air pollution in Lima surpassed the international standard by 122.1%. The average concentration of PTS (Particulate Matter) reached 166.57 micrograms per cubic meter, far above the international standard of 77 micrograms per cubic meter.

The main sources of air pollution in Lima are industrial activity and vehicle emissions. In 2009, 1.5 tons of lead and 810 tons of sulphur dioxide were emitted daily, four times the maximum allowed under Peruvian legislation. The increase in private vehicle ownership has led to heavy traffic jams in industrial and densely populated areas, contributing to poor air quality. The public transport system is inadequate, with 75% of people relying on it and 25% spending 2 hours per day travelling. As a result, those who depend on public transportation are more vulnerable to the harmful effects of air pollution.

The Peruvian government has implemented several measures to address air pollution in Lima and other cities. They have created an alert system for high pollution levels with three levels: watch, danger, and emergency. During an emergency, vulnerable individuals such as children, pregnant women, the elderly, and the ailing may be advised to stay indoors. The government has also invested in "Super Tree" technology, which acts like 1,200 real trees and purifies the air. The budget for environmental protection has increased to 71 million US dollars, and the government continues to develop regulations and laws to reduce pollution in major cities.

Water pollution from industrial waste and sewage

Water pollution is one of Peru's most pressing environmental concerns, with industrial waste, sewage, and oil-related waste being the primary sources. The country's renewable water resources total 1,746 cubic kilometres, with 86% used for agriculture and 7% for industrial activities. However, access to clean water is limited, especially in rural areas, where only 62% of the population has access to potable water.

Industrial activities and inadequate waste management contribute significantly to water pollution in Peru. The country's cities generate approximately 3 million tons of waste annually, and ineffective waste disposal systems lead to the contamination of water bodies. Industrial waste includes toxic chemicals and heavy metals released into water sources, posing significant risks to both human health and the environment.

Sewage is another critical component of water pollution in Peru. Inadequate sanitation infrastructure and insufficient treatment of wastewater allow pollutants to enter water bodies, degrading water quality and harming aquatic ecosystems. This issue is particularly concerning in areas of cultural and historical significance, such as Lake Titicaca in southeastern Peru. The lake's contamination severely impacts the health of the local population, and the lack of adequate monitoring and funding exacerbates the problem.

Oil-related waste is also a significant contributor to water pollution in Peru. Oil exploration and extraction activities can result in oil spills and the discharge of toxic chemicals into water sources. Additionally, Peru's mining industry, a significant driver of the country's economy, has led to the contamination of lakes and rivers with harmful waste. Gold mining, much of it illegal, is a significant source of pollution, along with the mining of other metals such as zinc, iron, and copper.

The Peruvian government has recognised the severity of the country's environmental issues and has taken steps to address them. President Alan García proposed the "water for all" strategic program, aiming to increase access to potable water and improve sanitation and sewage systems. Additionally, scientists in Peru are working on innovative solutions, such as using fortified microalgae to combat water pollution caused by mining waste.

Deforestation and soil erosion

Peru's economy is affected by several environmental issues, including water pollution, soil erosion, air pollution, and deforestation. Deforestation and soil erosion are closely linked, as trees anchor the soil with their roots, and their loss leads to widespread erosion.

Peru's topography makes it susceptible to soil erosion. The coast of Peru is subject to wind erosion, while water erosion is dominant in the Sierra region. Erosion also occurs in the High Selva when vegetation is cleared and in the Low Selva, where high-intensity rainfall impacts land farmed under slash-and-burn practices. The use of cover crops, mulching, and contoured rows can help control erosion to some extent, depending on the climate and slope.

The impact of deforestation-induced erosion is far-reaching. It leads to a loss of topsoil, which impacts crop yields and forces farmers to spend money on importing fertilisers or clearing additional forest areas. Erosion can also damage infrastructure, such as roads and highways, and impact the fisheries industry by causing siltation in rivers and smothering fish eggs.

In Peru, deforestation is driven by several factors, including the expansion of agriculture and cattle grazing, road projects, wood extraction, and population increase. Small-scale agriculture is the primary cause, but pressure from extractive industries, illegal mining, and narcotics trafficking also contribute. Between 2001 and 2018, Peru lost 2.2 million hectares of forest, and in 2020, the Peruvian Amazon lost more than 200,000 hectares.

The Peruvian government has recognised the urgency of addressing these issues. They have committed $5 million per year towards conservation efforts and are seeking additional funding from the international community. The government has also developed regulations and laws to reduce pollution in major cities and policies to decrease the deforestation rate.

Impact of mining and oil production

Peru has a wealth of mineral resources, including copper, iron, lead, zinc, bismuth, phosphates, and manganese. Gold and silver are also found extensively, as are other rare metals. The country has a long mining tradition stretching back to pre-Inca civilizations, and the industry is integral to the economy, contributing an average of 15% of GDP annually from 2017 to 2021. Mining investment in Peru totalled $5.4 billion in 2022, and the country is the world's second-largest producer of copper. Peru's proven reserves account for 9.1% of the world's copper, as well as sizeable shares of silver (17.8%), gold (5.6%), zinc (8%), and lead (6.2%).

However, the mining sector in Peru faces several challenges, including strong anti-mining protests and disruptions due to social and environmental concerns. The government's unpredictable stances on mining projects can create uncertainty for investors, and logistics risks are high, raising supply chain costs. Illegal mining also remains a significant problem, and the tax regime is relatively onerous for mining companies.

In addition to mining, Peru also has petroleum fields located along its far north coast and the northeastern part of Amazonia. Oil production has been an important part of the country's economy, with Peru becoming a net exporter of oil by 1980. However, oil production and exploration contribute to environmental issues, particularly water pollution. Oil-related waste is one of the main sources of water pollution in Peru, and there are concerns about the contamination of spiritually and historically significant bodies of water, such as Lake Titicaca.

The Peruvian government has taken steps to address the environmental impact of mining and oil production, including developing regulations and laws to reduce pollution and deforestation. They have also established a national greenhouse gas inventory system, INFOCARBONO, to help manage emissions. However, more needs to be done to fully address the environmental and social impacts of these industries.

Climate change and extreme weather events

Peru is highly vulnerable to the impacts of climate change, particularly due to its diverse geography and climate. The country is already experiencing more frequent and intense extreme weather events, which are having significant economic impacts. For example, the cost of extreme weather events in Peru between 1990 and 2017 was estimated to be $14.5 billion, with flooding and landslides being the most costly events.

One of the main ways that climate change is affecting Peru's economy is through its impact on agriculture, which is a key sector for the country. Climate change is causing more frequent and severe droughts and floods, which are damaging crops and reducing agricultural productivity. This is particularly true in the coastal regions, where water scarcity is already a major issue. It is estimated that by 2050, climate change could reduce agricultural production in Peru by up to 20%.

In addition to agriculture, climate change is also impacting Peru's water resources, energy sector, and public health. For example, melting glaciers are causing water shortages and increasing the risk of flooding in some areas. This is affecting not only agriculture but also hydropower generation and the availability of water for domestic and industrial use. The changing climate is also expanding the range of disease vectors, leading to an increase in the number of cases of vector-borne diseases such as dengue fever and malaria.

To mitigate the economic impacts of climate change, Peru is taking a number of adaption and resilience measures. For example, the country is investing in climate-resilient infrastructure, such as flood protection and early warning systems, and is working to diversify its economy away from climate-sensitive sectors. Peru is also a participant in the Paris Agreement on climate change and has committed to reducing its greenhouse gas emissions.

In conclusion, climate change and extreme weather events are already having significant economic impacts on Peru, particularly in the agriculture, water resources, and energy sectors. To mitigate these impacts and build a more resilient future, Peru is taking a range of adaption measures and working to reduce its greenhouse gas emissions. Addressing the challenges posed by climate change will require continued efforts and investments in resilient infrastructure, as well as a sustained focus on diversifying the country's economy.
