Cashew (2.7- 5.4kg of CO2 per year)

The cashew tree, scientifically known as Anacardium occidentale, is a tropical evergreen tree native to northeastern Brazil. It belongs to the Anacardiaceae family and is widely cultivated in tropical regions around the world for its edible nuts and other commercial uses.

Cashew trees, primarily cultivated for their nuts, also contribute to carbon sequestration and provide various environmental benefits. While specific data on carbon sequestration by cashew trees may vary, they are known to absorb carbon dioxide through photosynthesis, particularly when grown in agroforestry systems or mixed cropping environments.

Estimates suggest that a mature cashew tree can absorb approximately 6 to 12 pounds (2.7 to 5.4 kilograms) of carbon dioxide per year. However, these figures can vary depending on factors such as tree age, size, health, and environmental conditions.

Cashew trees are often grown in agroforestry systems, where they are integrated with other tree species and crops. Agroforestry systems enhance biodiversity, improve soil fertility, and provide additional sources of income for farmers. When grown alongside other trees, such as nitrogen-fixing species or fruit trees, cashew trees can contribute to higher levels of carbon sequestration compared to monoculture cashew plantations.

Additionally, cashew trees provide various ecosystem services, including soil erosion control, water retention, and habitat provision for wildlife. The nuts produced by cashew trees are a valuable agricultural commodity, supporting livelihoods and economic development in many regions where they are cultivated.

Promoting sustainable cashew cultivation practices, such as agroforestry and organic farming methods, can enhance the environmental benefits of cashew production while supporting the livelihoods of farmers and contributing to efforts to mitigate climate change.
