Abstract: Out of the 1,500 bamboo species occurring worldwide, India has around 130 bamboo species belonging to 23 genera, in which more than 50% of the Indain bamboo resource is confined to North-East. As many as 78 bamboo species (both indigenous and exotic) belonging to 19 genera have been reported from this region. Bamboo plays an important role in the socio-economy of tribal populace of the region. Most of the bamboo species available in the region are used for house construction, making fences around crop fields, and for making household articles, furniture etc. Existing four paper mills and other bamboo-based large scale industries of the region are the largest consumers of bamboo resource of the region. Newly emerging bamboo shoots and their processed forms are consumed as vegetables and food additives. Survey of the edible bamboo species in North East region revealed a total of 16 edible species among which 12 of them were highly commercial from edible point of view. Annual sales of fresh bamboo shoots were recorded to the tune of ca. 5,685 tonnes with a gross and net income of ca. Rs 37.76 million and Rs. 18.85 million per annum, respectively. The sales of fermented, roasted and boiled bamboo shoots were observed to the tune of ca. 680 tonnes/ yr with a gross and net income of Rs. 40.38 million and Rs. 22.90 rupees, respectively. Thus, by merchandizing only fresh and processed bamboo shoots for edible purpose in this region, this sector have generated employment opportunity which may employ approximately 3,285 persons throughout the year @ Rs 100 per day.

Keywords: Bamboo, Economic status, Demand-Supply, Productivity, Management
Abstract: India is one of the richest countries in Bamboo population covering 12.8% of the total forest land of the country. However, the yield per hectare is dimally low due to poor management, unscientific exploitation and low investment in raising preferred bamboo species.Very little attention has been paid until now to the management of natural bamboo stands and to ensure sustained supply of this raw material that results in constraining and reducing the potential benefits and value of bamboo applications. The current demand of bamboo for various purposes is estimated at 26.69 million tonnes as against the supply of 13.47 million tonnes. The average per hectare annual productivity of bamboo in India is about 1 MT/ha which is much less than the world ' s average. Low per hectare yield indicates poor management of existing bamboo plantations in forest and non-forest areas. It has been shown in case of some species that intensive cultural operations and scientific management of bamboo plantations can produce much higher yield. Establishment and management aspects of bamboo plantations for enhanced productivity are discussed in the paper.

Keywords: Bamboos, Andaman & Nicobar Islands
Abstract: Andaman & Nicobar Islands is the largest archipelago system consisting of cover 200 islands, over 300 inlets and constitute one of the hotspot of biodiversity. It is separated from mainland India by almost 1,000 km. There are 3,552 plant species known from these Islands. As regards bamboos not much work has been done because most of the areas are unexplored. The present authors have made extensive collection of bamboos of both Andaman and Nicobar group. There are 20 species wild and planted are reported from the islands. There is high degree of endemism in these islands. Six species viz. Dinochloa nicobarica, D. scandens var. andamanica (Bel bamboo), Schizostachyum andamanicum, S.kalpongianum, S.kurzii and S. rogersii are endemic to these islands. Dendrocalamus calostachys, Schizostachyum dullooa and S.polymorphum are now being reported from the wild for the first time. Rest all the species except Gigantochloa andamanica (Chatai bamboo) are under cultivation. There is a great demand for ballies or non-commerical timber in these Islands. Therefore bamboo can substitute the requirement of ballies, also can reduce the pressure on the forest.

Keywords: Biosorption, Copper, Coconut husk powder, Isotherms, Kinetic studies
Abstract: This investigation deals with the equilibrium and kinetic studies on biosorption of copper ions from aqueous solutions using coconut husk powder in a batch process. The results indicate that biosorption of copper is increased with an increase of biosorbent dosage and decrease with biosorbent size. A significant increase in percentage removal of copper was observed as pH value is increased from 1 to 7 and the percentage removal is decreased beyond pH 7. Increased initial concentration of copper in the aqueous solution results in lower biosorption. Freundlich and Langmuir isotherm models describe the present data very well indicating favourable biosorption. The biosorption follows pseudo-first-order kinetics.

Keywords: Fluoride ion, Adsorption, Low-cost adsorbents, Langmuir isotherm, Freundlich isotherm
Abstract: The study assesses the suitability of inexpensive leaf adsorbents to effectively remediate fluoride-contaminated water. The efficiency of the sorption of fluoride ion is affected by pH, contact time, adsorbent dose, type and size of adsorbents and initial fluoride ion concentration. The adsorption equilibrium is well correlated by Freundlich and Langmuir isotherms. Treated leaf powder was studied at various pHs (2, 4, 6 and 8) with a series of aqueous solutions containing 2, 3, 5, 6, 8, 10, 12 and 15 mg fluoride/L. At the highest F- ion concentration (15 mg/L), the F- ion level in the effluent gradually decreased to 0 mg/L within 180 min at 29.5 oC when the dose of adsorbent is 10 g/L in a sample of 50 mL volume. With lower F- ion concentrations (2 mg/L) in the feed solutions, the fluoride ion concentration steadily decreased reaching 0 mg/L after 150 min. Langmuir isotherm fits well for defluoridation of water using leaf powder.

Abstract: Biocompost was formed from press mud cake (PMC), flyash, Eichhornia crassipes and spent wash by bioinoculant Trichoderma viride in treatments viz. PTDE, T1 ,T2 ,T3 and T4 . Variations in temperature, pH and NPK of compost were also analysed. Biocompost maturity was evaluated by C/N ratio on 8th,16th, 24th and 32nd days. It was observed that Trichoderma growth is higher at pH 6.5 that hastened the decomposition process and improved the quality of compost. Immature and mature compost were evaluated by C:N. Seeds of Phaseolus aureus Roxb. cv. K-851 were sown in polybag culture (5 Kg soil + 159 g compost) @ 5 qt/acre or @ 12.50 kg/hac during July 2004, 05, 06 and 07. The results revealed significantly higher germination %, Vigour index, length of root and shoot, chlorophyll content, biological yield and harvest index. Bioinoculant decomposes the substrates early in T4 treatment and showed enhanced growth and yield due to mineralized nutrient status of compost.

Abstract: In a laboratory study, decolourisation of four reactive dyes (Cibacron Yellow C5G, Remazol Blue RGP, Remazol Red RGP and Remazol Golden, Yellow RGP) by modified photo-Fenton (UV- vis/ferrioxalate/H2O2 ) process under irradiation with sunlight was examined. Over 90% decolourisation occurred in 90-120 min for dye concentrations of 20, 50 and 100 mg/L, indicating the effectiveness of ferrioxalate complexes in decolourisation of even strongly coloured solutions. The study has demonstrated that modified photo-Fenton process is an effective process for decolourisation of reactive dyes. The process is useful for treatment of dyehouse waste in tropical and equatorial regions where sunlight is abundant.

Abstract: Attappady region in the Palghat district of Kerala is one of the severely degraded areas in the Kerala Western Ghats. Apart from the severe ecological, socio-economic, political and cultural problems, the region faces an acute water scarcity too. By identifying the severe ecological degradation and the consequent sociological problems, a watershed based massive ecorestoration project has been initiated in Attappady by the State government. The present study carried out in this area deals with the identification of groundwater potential zones. The groundwater potential zones of Attappady area generated from this study identifies five zones-very high, high, moderate, low and very low. The groundwater potential map generated in this study by making use of GIS tools will be useful in narrowing down the target areas for ground resistivity surveys in order to pinpoint the prospective well site. The results of this study can be used in the ongoing ecorestoration project at Attappady.
