Deforestation in Brazil in the context of "Convention on Biological Diversity"

Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is also the world's fifth-largest country by area and the seventh-largest by population, with over 213 million people. The country is a federation composed of 26 states and a Federal District, which hosts the capital, Brasília. Its most populous city is São Paulo, followed by Rio de Janeiro. Brazil has the most Portuguese speakers in the world and is the only country in the Americas where Portuguese is an official language.

Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers (4,655 mi). Covering roughly half of South America's land area, it borders all other countries and territories on the continent except Ecuador and Chile. Brazil encompasses a wide range of tropical and subtropical landscapes, as well as wetlands, savannas, plateaus, and low mountains. It contains most of the Amazon basin, including the world's largest river system and most extensive virgin tropical forest. Brazil has diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. The country ranks first among 17 megadiverse countries, with its natural heritage being the subject of significant global interest, as environmental degradation (through processes such as deforestation) directly affect global issues such as climate change and biodiversity loss.

Climate change in Brazil is causing higher temperatures and longer-lasting heatwaves, changing precipitation patterns, more intense wildfires and heightened fire risk. Brazil's hydropower, agriculture and urban water supplies will be affected. Brazil's rainforests, and the Amazon, are particularly at risk to climate change. At worst, large areas of the Amazon River basin could turn into savannah, with severe consequences for global climate and local livelihoods. Sea levels in Brazil are predicted to rise by more than 20cm by the middle of the century. Extreme weather events like droughts, flash floods, and urban flooding are causing annual losses of around R$13 billion (US$2.6 billion), equivalent to 0.1% of the country’s 2022 GDP. Climate impacts could exacerbate poverty.

Brazil's greenhouse gas emissions per person are higher than the global average, and Brazil is among the top 10 highest emitting countries. Greenhouse gas emissions by Brazil are over 4% of the annual world total, firstly due to cutting down trees in the Amazon rainforest, which emitted more carbon dioxide in the 2010s than it absorbed, and secondly from large cattle farms, where cows belch methane.
