In the north-eastern regions of India, shifting cultivation is traditional
and a dominant land use practice, leading to heavy soil erosion and severe
degradation of biodiversity. Agroforestry systems (AFS), which have great potential
for crop and livestock production, are the best alternative to overcome the adverse
effects of shifting cultivation. Agroforestry is an ecologically based, natural resource
management system that sustains production and benefits all those who use the land
by integrating trees on farms and in the agricultural landscape. In addition to
timber, fodder, fuelwood, medicines, etc, it conserves natural resources. In this paper,
the authors discuss the role of promising agroforestry systems and various
multipurpose trees (MPTs) in the conservation of natural resources. These systems
improved soil physical health through checking soil erosion and run-off, maintained
soil organic matter, enhanced soil chemical and biological properties, added nitrogen
input by trees and shrubs, and helped in the mining of minerals from lower horizons
by roots and their recycling through litter fall on the ground. Of the systems
studied, multistoreyed AFS [alder + tea + black pepper + annual agricultural
crops], silvi-horti-pastoral [alder + pineapple + fodder grasses] and natural forest
systems with suitable soil conservation measures are the most viable alternatives for
natural resource management and could sustain long-term soil productivity in the
highly degraded soil of this region.
