Why is the Amazon Rainforest Important for Food Security?
The Amazon rainforest is home to 400 billion trees and covers 6.7 million square kilometers, but the ‘Earth’s lungs’, as it is commonly referred to, is so much more than that.
Aside from being a key carbon sink, it also plays a critical role in supporting crop growth by stabilizing the climate and balancing water cycles.
In this infographic, our sponsor Brazil Potash looks at how the Amazon regulates rainfall and temperature and how crop yields can be optimized. Let’s dive in.
Rainfall as a Primary Water Source
“Flying rivers” are air currents that carry enormous amounts of water vapor over thousands of kilometers. These airborne rivers are responsible for influencing regional and global weather patterns, including rainfall.
The Amazon flying river cycle begins with water evaporating from the Atlantic Ocean. Wind currents then transport these vapors across the continent, exchanging moisture with the Amazon rainforest through evapotranspiration. Finally, these aerial rivers distribute the moisture as rain.
The trees in the Amazon rainforest release around 20 billion tonnes of water into the atmosphere daily—this is more water than the Mississippi River discharges in 13 months.
Because only around 6% of cropland in Brazil is irrigated, the region relies heavily on this rainfall as a (Read more…)
