Agroforestry
From PIW
Agroforestry describes a variety of land-use systems that combine woody plants, perennials, annuals and animals to achieve increase yield, reduced inputs, or manage soil fertility and erosion.
[edit] Kinds of Agroforestry
The following taxonomy of agroforestry systems is provided by Young (1997)
Agrosylivicultural (trees with crops)
- Rotational
- Shifting cultivation
- Managed tree fallows, including relay intercropping
- Taungya (crops followed by relay intercropping and short rotation forestry)
- Spatially mixed
- Trees on cropland
- Perennial-crop combinations
- Multi-strata systems (agroforests), including forest gardens, home gardens
- Spatially zoned
- Boundary planting
- Trees of erosion control structures
- Windbreaks and shelterbelts
- Hedgerow intercropping (alley cropping)
- Contour hedgerows
- Biomass transfer (cut and carry)
Sylvopastoral (trees with pastures and livestock)
- Spatial mixed
- Trees on pasture (parkland systems)
- Perennial crops with pastures (including orchards)
- Spatial zoned
- Hedges and live fences
- Fodder banks
Trees predominate (see also taungya)
- Farm and village forestry
- Reclamation agroforestry
Special components present
- Entomoforestry (trees with insects)
- Aquaforestry (trees with fish, mangrove aquaculture systems)
