The North-Western Himalayan population of the Indian elephant , Elephss maximus , used to be distributed contigually from the River Yamuna to the River Sharda in the past. This population was studied in the last decade of the twentieth century. The past migration patterns of elephants were compared with current movements in this region. The present day migration of elephants is localized and seems chiefly influenced by fodder and water requirements. The causes behind the fragmentation of elephant habitat mainly river valley projects and major construction works taken up after independence in the wake of development drive have been discussed in detail. The viability and ways means of restoring the possible corridors are discussed and a strategy for the long-term conservation of this population is suggested.

Decomposition rates and nutrient dynamics of Populus deltoides litter was investigated in three year old coppiced plantation situated in the mid-hills of Himachal Pradesh using the nylon net bags. Complete loss of Populus leaf litter was achieved in 20 months. The decomposition constant (k) was worked out to 1.27. Significant and a positive correlation was observed between decomposition and climatic parameters viz., rainfall and temperature (R2 = 0.61), whereas temperature did not exhibit any significant influence on the decomposition rate. Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) dynamics in decomposing litter revealed that concentration of nitrogen, phosphorus and calcium did not follow any specific trend during the decomposition process. Potassium and magnesium concentration, however, revealed a decreasing trend throughout the study period. Changes in absolute amount, on the other hand, followed a release pattern through the study period for N, K and Mg. P and Ca, however, depicted a three-phase pattern i.e. leaching, immobilization and release during the entire course of investigations.- North Indian Asiatic Elephant Population Conflict Wrrh Man with Reference to Crops Damage

The problem of raiding of agricultural crops by elephants in the foothills of Himalayas in Uttarakhand has been studied during the period- 1995-2000. The damage to the crops is classified in three categories viz. trampling, grazing and browsing. Maize is the crop most favoured by elephants followed by sugarcane, mustard and wheat. The damage to the crops varied from 21.63% to 12.47% in the villages studied. The damage remained nearly constant over the period. Seasonal migration, competition for water, reduction or fragmentation of natural habitat, replacement of crops by sumptuous crops etc. are the main reasons behind elephant raids. Forest fires infirmity, heavy biotic pressure resulting in increased competition for fodder and the element of chance are some other reasons for elephant raids. Some of the solutions suggested for the problem are making noise by beating canisters, shouting in groups, lighting fire and torches, digging trenches and using flashlights etc. Other measures suggested are immediate stoppage of all non forestry works within the elephant habitat and absolute ban on human encroachment in elephant habitat. Control over grazing by cattle in the habitat areas, provision of a buffer belt of thorny trees at the forest boundary, ban on cultivation of tempting crops such as sugarcane, elimination of disturbances in and around the natural corridor used by elephants for movement, promotion of eco-development activities in the adjoining villages , digging of elephant proof trenche s, and providing water inside elephant habitat during lean period etc. are also suggested. Traditional electric fences are found fatal and are not recommended while high voltage non fatal electric fences are suggested which can be powered by solar batteries. Anchored mela shikar, where trained domestic elephants are used to chase away rowdy wild elephants and capture and translocation of such rowdy wild elephants are also suggested as a solution.Keywords

Indian Forester, Vol 101, No 9 (1975), Pagination: 517-522Abstract
Jhingan gum is mostly obtained from natural exudation and sometimes by tapping. The gum finds its use in Confectionary, Calico-Printing, preparation of interior varnishes, plastering, white washing etc. About 10,41,100 Jhingan trees of different diameter classes are estimated to spread over Tarai, Siwalik and Vindhyan tract of Uttar Pradesh. With a view to standardise the technique of tapping, Jhingan trees of different diameter classes were selected for tapping under local and notching methods. The trees were subjected to tapping under the two different methods and yield data were recorded Statistical analysis or the data reveal that there is no significant difference in yield of Jhingan gum whether the trees are tapped by local method or notching method. On combining the yield of gum for the two different methods and plotting average yield per tree against different diameter classes, a close scrutiny of the graph reveals that apart from a few random fluctuation, Jhingan trees of 40-50 cm diameter class yield more gum.- SEM Surface Microtextures of Quartz Grains from Ganga and Yamuna River Sediments, Allahabad, U.P.

Quartz grain surface features of recent sediments saniples collected from vertical profiles developed in channel bar, point bar and natural levee deposits around the confluence of the Ganga and Yamuna rivers at Allahabnd, UP, were examined under the Scanning Electron Microscope (SEM). The study reveals the existence of several surface features as a result of mechanical and chemical action on the quartz grains.In channel bar and point bar deposits, mechanicaf features like low relief, v-shaped impact pits of coalescing nature and conchoidal fracture are dominating surface textures, which indicate the high-energy fluviatile depositional environment. Features like surface pits and surface solution are common in quartz grains from natural levee deposits. These surface textures owe their origin to chemical dissolution, which is possible only in low energy conditions associated with the deposition of natural levee and flood plain deposits.

The Coal Bed Methane (CBM), a dreadful mining hazard, became eco-friendly clean gas for the third world country when humanity is facing challenges against pollution and energy crisis. It is observed from the studies that the Korba and Ib valley coals have potential for CBM exploration whereas Umaria coals have negligible potential. Though, the Sohagpur coalfields (east of Umaria coalfield) have ample scope of CBM exploration.
In the absence of enough desorption data on gas content, the in situ gas content has been determined here following the theoretical interpretation of adsorption curve, taking into account of the moisture, ash, volatile matter, fixed carbon, depth of coal bed and the geothermal gradient. Data generation on gas content, gas saturation and gas sorption characteristics is vital for better definition of high quality coal prospects.

Systematic rock mass characterization is an integral part of rock engineering practices. In the present scenario several classifications are in used for rock mass characterization for tunnelling. The present paper discusses engineering geological investigations carried out for Punasa tunnel, a part of Narmada Sagar project. The horse shoe shaped tunnel is 3675.25 m long and 9 m in diameter. This straight and free flow tunnel has been constructed in basaltic lava flows erupted during Cretaceous to Eocene age, belonging to poor to fair rock mass rating (RMR) and extremely poor to good in tunnel quality (Q-system). The values of RMR and Q-system ranges from 29 to 74 and 0.0825 to 13.33 respectively.Keywords

The modern sediments of Ganga and Yamuna rivers at Allahabad, Uttar Pradesh are studied in 17 vertical sections of channel bar, point bar and natural levee deposits. Based on this study nine lithofacies, i.e. St, Sp2, Sp1, Sr1, Sr2, SI, Sh, FI and Fm (8-Sand and 1-Mud sub-lithofacies) have been identified. An attempt has been made to evolve a generalised lithofacies succession for channel bar, point bar and natural levee deposits. The channel bar exhibits the lithofacies succession of Sp2, Sp1, Sr2, Sr1, Sh and FI; Sp2, Sp1, Sr1 Sh and FI succession in point bar-and Sp2, Sp1, Sr1, Sh, FI and Fm lithofacies succession in natural levee deposits. No major difference in channel bar and point bar lithofacies succession have been found. The point bars are characterised by trough cross-bedded lithofacies - St, which are formed by the migration of 3-D dunes. The Fm lithofacies is characteristics of natural levee, the muddy deposits often show desiccation cracks. Deposition of mud takes place in low energy conditions mostly during receding floods.Keywords

Dietary proteins influence the labile protein stores of the animal tissues and in the process enzyme systems are not spared. Methods based on the capacity of different proteins to replenish the liver protein stores have been standardized and much ground has been covered during the past years. Major emphasis was laid upon the changes in the amount of liver protein, since the quantity of this tissue component appeared to offer the most appropriate estimate of the functionally effective liver mass.- Biochemical Studies on Indian Wild Legumes: (7) Effect of Acacia Arabica and Acacia Catechu Seed Protein Isolates on Total Liver Protein, Glycogen and Albumin Content, Xanthine Oxidase and Active Phosphorylase Activity in Normal Young Albino Rats

Eastern India is among the most backward regions of the country with underutilizedagricultural potential. Diversification towards high-value crops can be a promising strategy to enhance farmers’ economic welfare in the region. The present study analyses the major determinants and impact of crop diversification towards high-value crops on farmers’ economic welfare in the region using large farm household-level data and advanced matching estimation methods. The findings reveal that cultivation of high-value crops plays a significant role in enhancing farm income, consumption expenditure and reducing poverty. Growers need to allocate at least 40% area for high-value crops to have significant income enhancement and poverty reduction.Keywords

India is the largest producer of cotton in the world. For proper planning and designing of policies related to cotton, robust forecast of future production is utmost necessary. In this study, an effort has been made to model and forecast the cotton production of India using tuned-support vector regression (Tuned-SVR) model, and the importance of tuning has also been pointed out through this study. The Tuned-SVR performed better in both modelling and forecasting of cotton production compared to auto regressive integrated moving average and classical SVR modelsKeywords

The present study explores the pattern and extent of food-crop diversification and its implications on nutritional indicators in India using district-level data for the most recent period. It relied on data from land-use statistics and the National Family Health Survey 2015–16. We estimated the Simpson index for food-crop diversification and undernutrition index for nutritional status. The association of crop diversification and nutritional status was analysed employing bivariate copula function. The findings show striking regional differences in the extent of food-crop diversification and nutritional outcomes. The results of the copula function indicate a significant inverse relationship between crop diversification and undernutritionKeywords

Water harvesting is a critical component of any approach to alleviating India’s water crisis. Traditional rainwater harvesting systems are found in every region of the country. Haveli is one such system found in almost every village in the Bundelkhand region, Uttar Pradesh, India. A defunct Haveli in the Parasai–Sindh watershed of Jhansi district, Uttar Pradesh, was rejuvenated by providing a cement concrete core wall to the earthen embankment to address the problem of breaching, and the existing outlet was also expanded. This study was conducted from 2013 to 2019 to analyse the hydrology of the rejuvenated Haveli and to understand its impact on surface-water availability and recharging groundwater. The study period was divided based on long-term southwest monsoon (SWM) as wet (SWM > 20%), normal (SWM ± 20%) and dry (SWM < 20%) years. It was found that the Haveli could harvest about 1.91–2.0 times, 1.13–1.72 times and 0.2 times its capacity during a wet, normal and dry year, respectively. There was a 1.41 m difference in hydraulic head between pre- and post-Haveli rejuvenation in a wet year, whereas, a normal year, the difference was 2.71 m.Keywords

In developing nations such as India, malnutrition is a major nutritional and health challenge. Biofortification has the potential to be an effective instrument in India’s attempts to combat malnutrition. Expert opinion must be used to evaluate the factors related to the promotion, distribution and adoption of biofortified crops. The analytical hierarchy process (AHP) is one of the most often employed decision-making methods. However, conventional AHP is incapable of identifying ambiguity in human judgements. Fuzzy AHP has already been devised to overcome this limitation. Fuzzy AHP necessitates information in pairwise comparisons, which is not always easy to gather. In this context, the Fuzzy AHP technique based on the genetic algorithm has been proposed, which can compute the priority weight without using a pairwise comparison matrix by directly dealing with expert-provided data. The proposed approach has been illustrated using the opinions of 1600 farmers from Odisha, India.Keywords

As crop yield is determined by numerous input parameters, it is important to identify the most important variables/parameters and eliminate those that may reduce the accuracy of the prediction models. The feature selection algorithms assist in selecting only those relevant features for the prediction algorithms. Instead of a complete set of features, feature subsets give better results for the same algorithm with less computational time. Feature selection has the potential to play an important role in the agriculture domain, with the crop yield depending on multiple factors such as land use, water management, fertilizer application, other management practices and weather parameters. In the present study, feature selection algorithms such as forward selection, backward selection, random forest (RF) and least absolute shrinkage and selection operator (LASSO) have been applied to three different datasets. Regression forecasting models have been developed with selected features for all the algorithms. The forecasting performance of the proposed models was compared using statistical measures such as root mean square error, mean absolute prediction error and mean absolute deviation. A comparison was made among all the feature selection algorithms. The regression models developed with LASSO, RF and backward selection algorithms were the best for different datasets.Keywords
