Through Deforestation, Amazon rainforest and World Bank Group

Rainforests have decreased in size primarily due to deforestation. Between May 2000 and August 2006, Brazil lost nearly 150,000 square kilometres (58,000 sq mi) of forest, an area larger than Greece. According to the Living Planet Report 2010, deforestation continues at an alarming rate. At the Convention on Biological Diversity's 9th Conference, 67 ministers signed up to help achieve zero net deforestation by 2020. Due to deforestation the Amazon was a net emitter of greenhouse gas in the 2010s.

The effects include "severe financial losses, social setbacks, and biodiversity loss". Economic losses due to deforestation in Brazil could reach around 317 billion dollars per year, approximately 7 times higher in comparison to the cost of all commodities produced through deforestation. In 2023 the World Bank, published a report named: "A Balancing Act for Brazil's Amazonian States: An Economic Memorandum" proposing non-deforestation based economic program in the region of the Amazon rainforest.

History

The deforestation of the Atlantic forest, or Mata Atlântica, dates back to Portuguese colonization and the subsequent rapid development of urban centers. Before human-modification, the forest covered around 17% of Brazil's area. Unlike the Amazon, which has only faced extreme deforestation in recent years, the Atlantic Forest has been a long-lasting target for land development, speculation, and agricultural endeavors. Starting during the sixteenth century, the forest began facing pressure due to the unsustainable development of coffee, sugarcane, brazilwood, and cattle in the region.

In the 1940s Brazil began a program of national development in the Amazon Basin. President Getúlio Vargas declared emphatically that:

The Amazon, in the impact of our will and labor, will cease to be a simple chapter in the world, and made equivalent to other great rivers, shall become a chapter in the history of human civilization. Everything which has up to now been done in Amazonas, whether in agriculture or extractive industry... must be transformed into rational exploitation.

— Getúlio Vargas

Before the 1960s, much of the forest remained intact due to restrictions on access to the Amazon beyond partial clearing along the river banks. The poor soil made plantation-based agriculture unprofitable. The key point in deforestation of the Amazon came when colonists established farms in the forest in the 1960s. They farmed based on crop cultivation and used the slash and burn method. The colonists were unable to successfully manage their fields and the crops due to weed invasion and loss of soil fertility. Soils in the Amazon are productive for only a very short period of time after the land is cleared, so farmers there must constantly move and clear more and more land.

Amazonian colonization was dominated by cattle raising, not only because grass did grow in the poor soil, but also because ranching required little labor, generated decent profit, and awarded social status. However, farming led to extensive deforestation and environmental damage.

An estimated 30% of deforestation is due to small farmers; the rate of deforestation in areas they inhabit is greater than in areas occupied by medium and large ranchers, who own 89% of the Legal Amazon's private land. This underlines the importance of using previously cleared land for agriculture, rather than the usual, politically easier path of distributing still-forested areas. The number of small farmers versus large landholders fluctuates with economic and demographic pressures.
