“…The complete absence of previously reported uses for NTFPs was also prevalent across responses. It was surprising that no one reported on NTFP use, even though earlier studies had reported it in this area (Pattanaik et al 2008, Ambastha et al 2010.…”

“…Although participants named several species used for fuelwood, NTFP use (Table 2) was practically non-existent in current use patterns. Table 2 provides a list of mangrove timber and NFTPs reported from previous studies (Pattanaik et al 2008, Ambastha et al 2010 in the area and those that are currently used today (based on information collated from our interviews). Participants (90%) confirmed that dependence on mangrove species for fuelwood has drastically declined, and therefore often supplemented with alternative biomass sources.…”

Fuelwood, a forest resource, is used to satisfy local energy demands in many parts of the world. However, wood harvesting for subsistence or livelihood dependence is challenged by conservation narratives of forest degradation and loss in many parts of the Global South. Despite a vast network of protected areas that regulate access to resource extraction, forest dependence continues. Simultaneously, wood fuel continues to be used as a renewable source of energy in many developed countries. Energy transitions and the adoption of cleaner or low-carbon fuels are deeply socio-political and embedded in gender and social inequalities. Fuelwood dependence and adoption of alternate low-carbon technologies impact gender and social equity in intersectional ways. This study investigates the drivers of forest dependence on fuelwood and how that relates to broader narratives of forest degradation and conservation in Bhitarkanika National Park, a protected mangrove forest along the east coast of India. It utilizes the theory of access with surveys and focus groups to inquire about the socio-cultural beliefs and influences that shape reliance on firewood. Additionally, it also examines how access contributes to constraining or intensifying forest dependency, and how this dynamic interacts with intersectionality to uphold prevailing social conditions. The findings reveal a gendered differentiation in labor and values toward fuelwood collection and use. Women were found to be reluctant to change traditional ways of cooking and heating because of social responsibilities, structures, and preferences whereas men supported alternatives to fuelwood use, implying an invisible burden of conservation on women. Although forest dependence was largely for fuelwood, these dependencies stemmed from both social and cultural preferences, affirming the requirement for integrating cultural preferences and values that shape communities reliant on mangrove forests, to effectively devise practical conservation solutions involving alternative technologies or subsidized fuel options.

Cynometra iripa Kostel. is a Fabaceae species of mangrove used in traditional Ayurvedic medicine for treating inflammatory conditions. The present study aims to establish monographic botanical and chemical quality criteria for C. iripa leaf and bark as herbal substances and to evaluate their in vitro antioxidant potential. Macroscopic and microscopic qualitative and quantitative analyses, chemical LC-UV/DAD-ESI/MS profiling, and the quantification of key chemical classes were performed. Antioxidant activity was evaluated by DPPH and FRAP assays. Macroscopically, the leaf is asymmetrical with an emarginated apex and cuneate base. Microscopically, it shows features such as two-layered adaxial palisade parenchyma, vascular bundles surrounded by 3–6 layers of sclerenchyma, prismatic calcium oxalate crystals (5.89 ± 1.32 μm) along the fibers, paracytic stomata only on the abaxial epidermis (stomatal index–20.15), and non-glandular trichomes only on petiolules. The microscopic features of the bark include a broad cortex with large lignified sclereids, prismatic calcium oxalate crystals (8.24 ± 1.57 μm), and secondary phloem with distinct 2–5 seriated medullary rays without crystals. Chemical profile analysis revealed that phenolic derivatives, mainly condensed tannins and flavonoids, are the main classes identified. A total of 22 marker compounds were tentatively identified in both plant parts. The major compounds identified in the leaf were quercetin-3-O-glucoside and taxifolin pentoside and in the bark were B-type dimeric proanthocyanidins and taxifolin 3-O-rhamnoside. The total phenolics content was higher in the leaf (1521 ± 4.71 mg GAE/g dry weight), while the total flavonoids and condensed tannins content were higher in the bark (82 ± 0.58 mg CE/g and 1021 ± 5.51 mg CCE/g dry weight, respectively). A total of 70% of the hydroethanolic extracts of leaf and bark showed higher antioxidant activity than the ascorbic acid and concentration-dependent scavenging activity in the DPPH assay (IC50 23.95 ± 0.93 and 23.63 ± 1.37 µg/mL, respectively). A positive and statistically significant (p < 0.05) correlation between the phenol content and antioxidant activity was found. The results obtained will provide important clues for the quality control criteria of C. iripa leaf and bark, as well as for the knowledge of their pharmacological potential as possible anti-inflammatory agents with antioxidant activity.

“…Excoecaria agallocha L. (Euphorbiaceae) is a dioecious economically important widespread and common true mangrove tree that grows in the Sundarbans and other coastal mangrove areas in the wet tropics. The plants of E. agallocha have been reported for their antimicrobial, antioxidant, antiviral, antifungal and anticancer activities (Pattanaik et al 2008;Patra et al 2009;Simlai & Roy 2013). Besides that, mangrove forests are mostly essential for ecosystem services and biodiversity.…”

Excoecaria agallocha is a dioecious mangrove species, reported to have various medicinal properties. This study compares the gender-related biological activities between the sexes of E. agallocha in accordance with morpho-biochemical parameters which indicate their fitness over various environmental stresses as well as some information about the investment of their resources over defence and growth. For this investigation, mature sun leaves of E. agallocha were collected from each sex from three different ecological regions like Bokkhali, Jharkhali, and Kolkata, West Bengal. The comparative study found that leaf of female plants yielded more compounds than males and also resulted in higher anti-bacterial, reducing power, total antioxidant, and lipid peroxidation activities. Female leaves also showed higher concentrations of biochemical constituents like chlorophyll a, chlorophyll b, total carotenoids, total phenolic compounds and total protein content than male leaves. However, leaf area of all-male leaves in all sites was found to be greater than female leaves. The differences in growth rate and secondary metabolite content-based defences between sexes suggest that females invest resources in defences or resistance (Relative electrolytic leakages and TBARS content), whereas male invests their resources in growth (Leaf area) or tolerance. The present study strongly suggests that the female plant’s yields are more beneficial in terms of medicinal properties as compared to the male plant.
