Agroforestry: Southern Region Resources on Sustainable Woodland Management and Land Use Conservation

By convention, agriculture, horticulture, and forestry are treated as isolated land uses, each requiring physical separation and independent production techniques. However, distinct boundaries between these land uses often blur. Trees and agriculture frequently occur together in farm environments, either where single trees grow in agricultural fields and pastures, or where stands of trees adjoin fields and pastures.

Agroforestry -- a sustainable land-use system that involves the intentional integration and management of trees, crops, and/or livestock in a single management unit -- takes advantage of the interfaces between trees and agricultural activities. If properly managed, these interactions can provide net benefits to the farm enterprise and the agroecosystem. As an association of plant and/or animal communities, agroforestry systems are deliberately designed to optimize use of spatial, temporal and physical resources, by maximizing positive interactions and minimizing negative ones between trees, crops and animals. For example, trees in these systems are capable of improving soil nutrient levels, thereby improving overall system productivity. Trees are also capable of capturing and recycling lost soil nutrients and are, thus, a potential moderating factor in groundwater pollution caused by leaching of nitrates. In addition, trees on agricultural lands offer landowners the possibility of producing bioenergy products or accruing carbon credits via the sequestration of stable carbon stock, an added incentive for adopting alley cropping -- a type of agroforestry practice.

Agroforestry can be categorized into five basic types: windbreaks, alley cropping, silvopasture, riparian buffers and forest farming. Within each is a host of options available to landowners and farmers.

Alley cropping involves the planting of timber, fruit or nut trees in single or multiple rows on agricultural lands, with crops or forages cultivated between the rows, or alleyways.

Forest farming is the planting and harvesting of non-timber products, namely medicinal and edible plants.

A riparian buffer is a vegetative zone, mainly shrubs and trees, along a water source, such as a stream, river or watershed that protects the area from degraded water quality and non-point source pollution.

Silvopasture is an agroforestry system that incorporates forage crops and animal production in a woodland, forested, or tree plantation environment.

A windbreak is a process of planting fast-growing trees, shrubs or grasses, mainly to mitigate wind-related agriculture problems.

Agroforestry is growing in popularity with both landowners and farmers interested in sustainable agriculture. By emulating natural ecosystems more closely than standard agriculture, agroforestry techniques enable environmental sustainability and stewardship objectives to be met along with commodity-output objectives. Agroforestry also enables landowners to diversify production activities and outputs from a limited land base, resulting in increased long-range economic security.
