Case Study: The Amazon Rainforest
Case Study: The Amazon Rainforest The Amazon in context. Tropical rainforests are often considered to be the "cradles of biodiversity." Though they cover only about 6% of the Earth's land surface, they are home to over 50% of global biodiversity. Rainforests also take in massive amounts of carbon dioxide and release oxygen through ...
Amazon Deforestation: A Regional Conservation Case Study
The study, called "Contribution of the Amazon protected areas program to forest conservation," measured historical deforestation from 2008 to 2020 using satellite deforestation data called PRODES, and compared deforestation rates in ARPA supported areas to non-ARPA supported areas. It was determined that ARPA supported areas experienced 9-39% ...

Study Shows the Impacts of Deforestation and Forest Burning on
A new study, co-authored by a team of researchers including UConn Ecology and Evolutionary Biology researcher Cory Merow provides the first quantitative assessment of how environmental policies on deforestation, along with forest fires and drought, have impacted the diversity of plants and animals in the Amazon.
Amazon Deforestation and Climate Change
The Amazon rain forest absorbs one-fourth of the CO2 absorbed by all the land on Earth. The amount absorbed today, however, is 30% less than it was in the 1990s because of deforestation. A major motive for deforestation is cattle ranching. China, the United States, and other countries have created a consumer demand for beef, so clearing land ...
Sustainable Management of the Amazon Rainforest
Sustainable management ensures rainforests are worth. more than the value of the timber and other resources that can be extracted, such as gold. An example of this is sustainable foresty, which balances the removal of trees to sell with the conservation of the forest. Selective logging involves only removing a small number of trees, allowing ...

PDF The Deforestation of the Amazon: A Case Study in Understanding
Based on estimates of 1% annual tropical forest loss, the Amazon may be losing as many as 11 to 16 species per day (Wilson 1989), and the resulting ecosystems are often highly degraded (Buschbacher 1986). Te deforestation of Amazonia presents a challenging study of the interactions among people, their values, and the environment.
