Cross-sectional survey research design was applied for collecting quantitative data using a semi-structured questionnaire administered to 384 households stratified on the basis of PFM participation status. Qualitative data was collected through focused group discussions using a checklist and key informant interviews using an interview schedule. Using Statistical Package for Social Sciences version 25, Binomial regression with Wald Chi-square was analyzed to identify factors perceived to be significantly influencing benefits for PFM participants and Pearson Chi-square to compare factors perceived to be affecting PFM and non-PFM participants. CFA members participation in PFM was significantly and positively affected by benefits of PFM income generating activities and forest products accessed in the forest. Benefits linked to Plantation Establishment for Livelihood Improvement System (PELIS) for CFA members were significantly reduced by enforcement of moratorium policy since February 2018, diseases and pests, poor PELIS guideline adherence and animal damage. Benefits related to state forest access for firewood by the CFA members were negatively influenced by the moratorium policy. Diseases and pests affected benefits associated with bee keeping significantly. Comparing factors under different PFM participation status, crop production was significantly affected by policy changes, pest and diseases, animal damage and PELIS guideline adherence for CFA members than for Non-CFA members. Policy changes also affected the CFA members significantly in firewood collection and access to fodder in the state forest than the Non-CFA members. Hence, sustainable community participation in Upper Imenti Forest management requires: increasing PFM benefits, addressing factors reducing benefits and enhancing active participation of CFA members in PFM related decision-making processes.展开更多

Data were obtained through questionnaires, interviews, focus group discussions, participatory rural appraisal and field observations. The study revealed that the most remarkable local institutions connected to forest biodiversity management include： Village Natural Resources Man- agement Committee （92%）, tree nursery group （79.4%）, beekeep- ing groups （61.1%）, fish fanning （43.3%）, livestock rearing group （33.9%）. Main activities carried out by local institutions which directly contribute to the sustainability Of forest reserve include： forest patrols, fire extinguish, preparation of fire breaks, plant- ing of trees along the forest boundaries, creation of awareness, arresting of forest defaulters, participation in income generation activities. For the purpose of realization that local communities are capable of managing forest biodiversity through their traditional institutions, the policy should provide tangible opportunity for local communities to meet their needs as they manage the forests.展开更多

However, the plant dies after gum exudation. The indigenous tapping techniques used by local people were examined in Gujarat, India to dis-cover the scientific basis behind these techniques： selection of gum in-ducer, season of tapping, and plant parts to be tapped. First, the presence of Xanthomonas axonopodis pv. commiphorae （Xac） in the gum suspen-sion used for tapping was established. This bacterium induces gum ooz-ing from the tapped plants and later, causes them to die off. The popula-tion of Xac in gum was found to decrease with the age of the gum. With that, fresh gum increased the tapping success. Second, local people pre-ferred tapping during the warm season, which we validated by determin-ing that Xac growth was best at 30 ＆#176;C. Tapping during September （mean temperature 25.7-30.0 ＆#176;C） clearly favoured growth of the pathogen and yielded maximum guggul. Multiple tapping on a mature tree ensured maximum gum extraction before its death. Finally, application of in-digenous technology under natural plant stands by the local people en-sured availability of this important raw drug for consumption. Our study established that the age-old traditional methods have a strong scientific basis. However, it is imperative to formulate strategies based on con-temporary scientific understanding to protect this natural resource before it becomes extinct.展开更多
