Drivers of Exploitation and Inequity in Non‐Timber Forest Products (NTFP) Value Chains: The Case of Indian Bay Leaf in Nepal and India

Dyutiman Choudhary; S.P. Kala; N.P. Todaria; Sabyasachi Dasgupta; Michael Kollmair

This article presents the findings of a study that analysed the Indian Bay Leaf (Cinnamomum tamala) Nees and Eberm value chain (VC) in Uttarakhand, India and Udayapur, Nepal. The results show that bay‐leaf VCs are loosely integrated and consist of stakeholders with asymmetrical power relations and different priorities. Traders in India dominate the chains and inappropriate standards lead to the exploitation of small producers and inequity in the chain. Policy measures are suggested for improving co‐ordination and competitiveness in the bay‐leaf VC which could be applied to the NTFP sector as a whole.

This article highlights the results of an action research to upgrade mountain farmers of bay leaf (Cinnamomum tamala Nees and Eberm) in Udayapur district of Nepal. Farmers received low prices, lacked market information, capacities, and institutional mechanisms, and were exploited by traders. To address these constraints, three independent but interlinked pro-poor value chain (VC) upgrading strategies comprising VC coordination upgrading and horizontal and vertical contractualization were implemented. Information was collected from focus-group discussions with collectors, traders, and facilitators, and a questionnaire was used to collect pre- and postintervention data (n = 120). VC upgrading strategies improved harvesting practices, increased farmers’ bargaining power, and led to a threefold increase in price, which increased household incomes. Results demonstrated improved terms of participation of farmers and a general increase in market price of bay leaf in Udayapur. The study approach can be up scaled to reduce poverty from high value products.

Impact and ecosystem service of forest and sacred grove as saviour of water quantity and quality in Garhwal Himalaya, India

The present study was conducted in environs of the sacred grove of Garhwal Himalaya, India, with a view to assess the impacts of sacred groves and forests on the quality and quantity of water and also to assess the effect of seasonality on perennial stream quality. Water samples were collected from three randomly selected stream spots of both the sacred grove dominated by deodar (Cedrus deodara) and the non-sacred patch dominated by oak (Quercus leucotrichophora). Water samples from both patches were within the World Health Organization (WHO) standard limits. Based on an already established water quality index, water quality of both patches was safe for domestic and irrigation purposes but needs treatment for drinking purposes. Results of the present study also showed a very prominent impact of forest type as well as management condition on water quality and quantity. The water discharge from an oak forest shows more consistency than the discharge from a deodar forest. Due to the presence of the sacred grove, the area has become the source of good quality water supply during lean season for the surrounding villages. Water quality and quantity differed along with the change in season. The sacred grove and the existing forest leave a great impression on local dwellers, as due to its presence, local dwellers never run out of water supply during the dry season. As a result, the villagers sincerely want to protect the area for the sake of their own well-being.

Effects of harvesting on productivity of bay leaf tree (Cinnamomum tamala Nees & Eberm): Case from Udayapur district of Nepal

Dyutiman Choudhary; S.P. Kala; N. P. Todaria; Sabyasachi Dasgupta; Michael Kollmair

Cultivation of bay leaves (Cinnamomum tamala Nees & Eberm) to fulfil household income needs is a long established practice in Udayapur district of Nepal. The practices adopted by farmers for bay leaf harvesting have not, however, been validated by scientific investigation for their sustainability. To investigate the impacts of harvesting on the yield of branch, leaves and biomass of leaves, a two-year research project was conducted in farm fields at Kopche village of Routa VDC in Udayapur district, Nepal. Four different harvesting treatments, the orientation and the order of branches were taken as independent variables to test their effects on number of branches, leaves and biomass of leaves. Orientation, harvesting treatments and order of branches had a significant effect on the number of branches, but not on the number of leaves or biomass (fresh and dry weight) of leaves in the year of harvest. Between two consecutive harvests there was no significant difference in the number of branches, leaves or biomass. Lower two-thirds portion of the trees produced the largest number of leaves and branches of the fourth order in both years. Therefore, lower two-thirds portion of the trees were suitable for harvesting. Our findings support farmer experience that no change in productivity of leaves is observed when harvesting each year. For long term sustainability, harvesting should be conducted without debarking of trees or damage to branches. Our findings could be extrapolated to and tested in other areas with different access and user rights where the rotation for harvest is fixed or regulated without research evidence.
