Environmental impacts of large-scale mining in Zambia.
Zambia is a country in Southern Africa that is rich in mineral resources. The mining landscape in Zambia covers the production of multiple mineral raw materials, including copper, cobalt, gold, nickel, manganese, emeralds, beryllium, myriad gemstones, sulfur, zinc, coal, iron ore, steel, limestone, uranium and other platinum-group metals. Copper is the main export commodity.
Consequences development of large-scale mining in Zambia
Mining has to Zambia's economy for many years, but it also has significant environmental impacts, especially large-scale mining. Here are some of the ecological impacts of large-scale mining in Zambia: ● Deforestation: Large-scale mining operations in Zambia often require the clearing of large areas of forest, which can have a significant impact on the local ecosystem. Deforestation can lead to soil erosion, loss of biodiversity, and changes in the local climate. ● Water pollution: Mining activities can contaminate nearby water sources with chemicals and heavy metals, which can significantly impact the health of humans and animals. Mining activities can lead to the contamination of drinking water sources and a reduction in the quality of aquatic habitats. ● Air pollution: Mining activities can also release large amounts of dust and other pollutants into the air, significantly impacting air quality and public health. Pollutants can cause respiratory problems and other health issues, especially for people near mining sites. ● Soil degradation: Large-scale mining operations can also lead to the degradation of soil quality, which can have long-term impacts on agriculture and the local ecosystem. Mining activities can lead to reduced soil fertility, erosion, and changes in soil chemistry. ● Habitat destruction: Mining operations can destroy the natural habitats of local flora and fauna, leading to a loss of biodiversity and potentially causing the extinction of some species. Overall, large-scale mining operations in Zambia have significant environmental impacts that can have long-lasting effects on the local ecosystem and human health. Mining companies need to take steps to mitigate these impacts and minimize their ecological footprint.
Health effects for people of mining
Lead exposure mainly results from ingesting lead-contaminated soil or food but also through inhalation and penetration through the skin. People affected have high Blood Lead Levels (BLLs), a silent killer causing anemia, headaches, seizures, abdominal pain, neurological symptoms and developmental delays.

Timelines
2022
October
The Zambian Ministry of Mines and Minerals Development gave a 90-day amnesty to all illegal miners to legalize operations. It also set up and opened a Cadastre Department and announced that the issuance of mining licenses would be restricted to five per applicant.
2009
The world economic crisis badly hit Zambia.
2003
Exports of nonmetals increased by 25% and accounted for 38% of all export earnings, previously 35%. The Zambian government has been granting licenses to international resource companies to prospect for minerals such as nickel, tin, copper, and uranium. The government of Zambia hopes that nickel will take over from copper as the country's top metallic export.
2002
Following the privatization of the industry, copper production rebounded to 337,000 metric tons. Improvements in the world copper market have magnified the effect of this volume increase on revenues and foreign exchange earnings.
1998
The Zambian economy has historically been based on the copper mining industry. The output of copper had fallen to a low of 228,000 metric tons after a 30-year decline in production due to a lack of investment, low copper prices, and uncertainty over privatization.
1995
Despite limited debt relief, Zambia's per capita foreign debt remained among the highest in the world.
1975
The price of copper, Zambia's principal export, suffered a severe decline worldwide. In Zambia's situation, the cost of transporting great copper distances to the market was an additional strain. Zambia turned to foreign and international lenders for relief, but copper prices remained depressed, making it increasingly difficult to service its growing debt.
