Strategy for mitigating fuel wood induced forest degradation in tribal land- scape of Jharkhand, India

The study was conducted to examine the extent of fuel wood dependence in the forests and mitigate the pressure by evolving an eco-friendly strategy in Bundu block of Ranchi District in Jharkhand, India. Multi-stage random sampling technique was employed to select 164 tribal households from 9 villages. Well -structured pre-tested interview schedule and non-participant observations were used for data collection, which were analyzed by descriptive statistics. Results revealed that the total extraction of fuel wood from different sources was 598.60 tons annum-1 @ of 0.68 tons capita-1 annum-1, of which, 308.16 tons annum-1 was secured from forests, 133.31 tons annum-1 from agriculture field, 90.45 tons annum-1 from community land and 66.68 tons annum-1 from homesteads. The fuel wood use breakup recorded 486.24 tons annum-1 for cooking, 45.79 tons annum-1 by cottage industries, 41.07 tons annum-1 for heating, 18.80 tons annum-1 for community function and 6.70 tons annum-1 for others. The forests were exposed to fuel wood pressure of 308.16 tons annum-1 (51.48%) posing ample deforestation and degradation. A strategy consisted of energy interventions viz., biogas production (85351.60 m 3 annum-1), agroforestry (36.84 tons annum-1) and energy plantation (92.10 tons annum-1) is proposed, the implementation of which can mitigate the fuel wood induced forest degradation besides fuel wood security of 846.14 tons annum-1 against the present fuel wood procurement of 598.60 tons annum-1. The strategy designed needs to be implemented to substitute the current unsustainable extraction of fuel wood, safeguard the future fuel wood predicament and eliminate the fuel wood pressure on forests

Wasteland reclamation strategy for household timber security of tribes in Jharkhand, India

The study sought to examine the timber dependency on forests and evolve wasteland reclamation strategy to eliminate the forest dependency in Bundu block of Ranchi District in Jharkhand, India. Multi-stage random sampling technique was applied to select 164 tribal households from 9 sample villages. Data were collected using structured interviews and non-participant observations which were analyzed using descriptive statistics viz., frequency, percentage, mean and range. Results revealed that forests contributed maximum timber (136.36 m3 annum-1) followed by traditional agroforestry (69.09 m3 annum-1), community forestry (41.33 m3 annum-1) and homestead forestry (35.71 m3 annum-1). Timber extracted is mostly consumed in housing (124.66 m3 annum-1) followed by agricultural implements (82.71 m3 annum-1), furniture (35.25 m3 annum-1), carts/ carriages (17.60 m3 annum-1), fencing (10.23 m3 annum-1), cattle shed/ store house (9.10 m3 annum-1) and others (2.94 m3 annum-1). Forests were exposed to timber pressure of 136.36 m3 annum-1 (48.27%) posing ample deforestation and degradation. The strategy consisted of timber and bamboo plantations is designed which would secure 1065.60 m3 annum-1 of timber, 0.455 lakh annum-1 of bamboo culms, 568.26 tons annum-1 of bamboo leaf and agricultural products. The strategy would yield income of Rs. 34210.78 household-1 annum-1 and employment of 67.15 person-days household-1 annum-1. Financial viability of proposed interventions has been worked out by meticulous economic calculations of Net Present Value, Benefit Cost Ratio and Internal Rate of Return. The execution of strategy would eliminate the current unsustainable timber extraction, safeguard the future timber predicament and ensure environmental security
