The Wonders of Agroforestry Farming

The USDA elucidates that agroforestry is “putting the right tree, in the right place, for the right purpose.” This seamless integration of trees and shrubs has been employed for ages to fashion climate-resilient landscapes that bestow benefits upon water, soil, crops, and animals.

Nowadays, it is gaining increasing prevalence across the U.S. as a means to safeguard crops from extreme weather conditions and guarantee the success of produce. Agroforestry is highly resilient to climate variations and contributes significantly to global food security by protecting crops and livestock.

What Is Agroforestry?

Agroforestry refers to the deliberate incorporation of trees and shrubs into farming systems encompassing both crops and animals. The objective of agroforestry is to generate environmental, economic, and social advantages. According to the USDA, this farming approach enhances the agricultural landscapes, watersheds, and communities of the country.

There exist several classifications of agroforestry, including the following:

1. Alley cropping: Where crops are planted between rows of trees as the trees mature. The crops utilized might comprise fruits, vegetables, herbs, flowers, and more.
2. Forest farming: Also known as multi-story cropping, this occurs when crops are grown beneath a forest canopy to provide shade.
3. Silvopasture: When livestock, their food sources, and trees coexist on the same plot of land to offer shade and shelter.
4. Riparian forest buffers: When trees, shrubs, and grasses are planted along rivers and streams to establish a buffer that filters runoff and averts erosion.
5. Windbreaks: Also referred to as hedgerows and shelter belts, this is when trees and shrubs are employed to shield crops, animals, and oil from the wind, dust, or snow.

Benefits

Agroforestry techniques have been utilized worldwide for centuries, but they are becoming more widespread in the U.S. as they assist farmers in mitigating the risks posed by severe weather, environmental impacts, and product price fluctuations.

A 2017 review published in Environmental Science and Pollution Research International discovered that agroforestry plays a crucial role in global climate change mitigation and is capable of surmounting various financial, technical, and institutional barriers to exert a positive influence, including carbon sequestration.

And a 2022 study published in Environmental Monitoring and Assessment indicates that agroforestry reduces soil loss and runoff in comparison to sole crop cultivation. This technique enhances productivity and profitability while minimizing energy consumption.

The benefits of agroforestry encompass:

1. Protecting the soil, crops, animals, and homes from extreme weather conditions
2. Enhancing the food supply
3. Trapping snow and runoff
4. Reducing erosion
5. Providing shade and shelter for animals
6. Mitigating odors
7. Sequestering carbon and other greenhouse gases
8. Improving water quality
9. Enhancing pollinator habitat
10. Mitigating weather and product risks for farmers
11. Producing trees for timber and other products
12. Bringing nutrients from the ground to the surface
13. Building soil matter

Best Agroforestry Trees

The selection of the most suitable trees for agroforestry is highly contingent on the objectives for that particular farm or land. There are multiple reasons for integrating trees, crops, and livestock, such as climate control, providing shelter for animals, shading for crops, and more.

It is also essential to consider your local climate and opt for trees that are well-adapted to your region.

Once you have sorted out the logistics, you can make a choice among the best tree varieties. Here are some popular trees employed in agroforestry systems in the U.S. (including as part of Ancient Nutrition’s R.A.N.C.H. Project) and beyond:

• Chestnuts
• White Oak
• Southern Red Oak
• Silk Oak
• Eastern Red Cedar
• White Pine
• Sugar Maple
• Black Walnut
• Shagbark Hickory
• Pecan
• Hazelnut
• Black Walnut
• Red Mulberry
• Elderberry
• Dogwood
• Common Apple
• Black Elder
• Arrowwood
• Sandalwood
• Moringa

Agroforestry Examples

Although it has not always been labeled as agroforestry, this concept has been in use around the world since ancient times. The integration of trees, crops, and livestock enabled farmers and settlers to not only produce their own food but also provide shelter, clothing, medicine, and more.

The Food and Agriculture Organization of the U.S. suggests that the farming technique dates back to the Spanish Dehesas, 4,500 years ago, when the pasture was dotted with scattered oak trees. In Europe, until the Middle Ages, trees were planted parallel to crops. Trees covered ground crops in Africa, Asia, and the Americas.

Today, perhaps due to climate changes and the occurrence of weather disasters, agroforestry techniques are being utilized more frequently in the U.S., Europe, Australia, and New Zealand. New classifications within the agroforestry method are emerging to address specific environmental issues or necessities, and agricultural programs are supporting farmers in creating these integrated systems.

Farms throughout the U.S. are adopting this technique to manage their risks and enhance resource sustainability. One such farm is owned and operated by Ancient Nutrition, as part of the R.A.N.C.H. Project, which encompasses over 4,000 acres of regenerative agriculture that employs agroforestry techniques.

Agroforestry vs. Silvopastoral

Silvopastoral systems integrate forestry and the grazing of domesticated animals on farms and pastures. This is a category within the agroforestry farming method that holds numerous advantages, including reducing heat stress in livestock, providing protection against wind and weather, improving wildlife diversity and water quality, and supplying food for animals.

A silvopastoral system typically includes pasture grasses and fertilization, contributing to the health of the soil. Rotational grazing is crucial for well-managed silvopastoral systems as it minimizes damage to trees and contributes to the long-term regeneration of soil and trees.

Final Thoughts

• Agroforestry is the intentional integration of trees and shrubs into farming systems involving both crops and animals.
• There are several categories of agroforestry, such as alley cropping, forest farming, and silvopasture farming.
• There are numerous benefits of agroforestry, including providing weather protection, enhancing the food supply, improving water quality, reducing erosion, and mitigating climate change.
• The trees used in the agroforestry system depend on the region and goals, but may include trees from species such as oak, pine, maple, and cedar, among many others.
