Assessing
Ecological Sustainability of Non-Timber Forest Produce Extraction:
The Indian Scenario
Ghazala Shahabuddin and Soumya Prasad
Non-timber
forest products (NTFP) are extensively extracted from Indian forests,
and their role in rural and forest economies is immense. However,
the long-term ecological sustainability of NTFP extraction with
respect to resource populations, dependent animal species and ecosystem
functioning has remained largely unexamined. In this article NTFP
research undertaken in India is reviewed in an attempt to understand
issues related to ecological sustainability. There is a glaring
scarcity of systematic research on ecological aspects of NTFP extraction
in India. From the few available studies, it appears that species
differ in their responses to harvest depending on the plant part
extracted, natural history attributes and harvesting techniques.
However, regeneration and population densities of some NTFP species
are reported to be adversely affected by extraction. Such adverse
effects, though, cannot be attributed to NTFP harvests alone, but
rather to a combination of harvests, damaging harvesting practices
and accompanying anthropogenic disturbances such as fire, grazing
and fuel wood collection. There is little information on the long-term
indirect effects of NTFP extraction on dependent animal species.
The available literature also indicates a disturbing trend of ecosystem
simplification due to intensive forest use, including extraction
of NTFP,
which may gradually lead to the weeding out of vulnerable plant
species from Indian forests. Much more research is required before
it can be clearly understood to what extent and in what ways livelihoods
based on NTFP can be compatible with biodiversity conservation.
