Abstract: High and sustainable agricultural growth is essential for eradication of poverty, hunger and undernourishment. But agriculture is underperforming in many developing countries for a number of reasons. Among these is the fact that women lack the resources and opportuninties they need to make the most productive use of their time. Although women have entered the labour force in large numbers across much of the developing world in the past quarter century, this increased participation has not translated into equal employment opportunities or equal earnings of men and women.

Abstract: Few insects are as universally and as passionately loathed across the world as termites are. As is the case with mosquitoes and houseflies, the aim of nearly everyone is to find a way to eradicate the termites or to at least reduce their mumbers so drastically that they cease to be a bother. But termites are essential for the survival of humankind. Alongside ants and earthworms, termites are the main tillers, movers and rejuvenators of the world ' s soil.

Abstract: The red panda (Ailurus fulgens) is a scarcely known threatened mammal in Asia. Habitat fragmentation, poaching and human disturbance are the main threats currently faced by red pandas throughout their distribution range. We studied the habitat selection of red panda in the Meigu Dafengding National Nature Reserve (MDNNR) in the Hengduan Mountains of China between December 2006 and February 2007. Our survey confirmed red panda presence in most of the MDNNR and also that they select a specific habitat type based on micro-habitats. The red pandas preferred mixed broadleaved and coniferous forest habitat with bamboo understorey, as bamboo was their main source of food. They preferred habitats with more than 45 slope and avoided habitats with 15-30 slope. They also preferred the southern aspect and avoided the northeast-facing aspect. We found that most red panda sign was close to a water resource. There are more than 10 villages in the Reserve and the villagers depend directly or indirectly on the Reserve for their livelihood. Livestock grazing, human disturbances, poaching, illegal wood and other forest product collection for local use or commercial purposes are all exerting pressure on the area. Our study on the habitat selection of the red panda for the winter season in the MDNNR will be helpful for further understanding of the ecology and also help to the government to devise a conservation strategy and habitat conservation planning for the Reserve.

Keywords: Amorphous ferri-alumino silicate, labile carbon, short-range order minerals, total organic carbon.
Abstract: The relationship of short-range order (SRO) minerals, their role in carbon sequestration capacity and its relation with clay carbon was studied in three soils with contrasting characteristics. The study was carried out in two phases, viz. sorghum-sudangrass depletion experiment and test crop harvest, the clays were separated and fractionated into fine and coarse clay humus complexes and SRO minerals, total organic carbon (TOC) and labile carbon (LC) contents were estimated in them. In fine clay humus complex, mean TOC was significantly higher in Vertisol (3.01%), depleted fertility (2.96 %) and rhizosphere (2.87%) samples. LC was significantly higher in depleted fertility status (1.74%), Vertisol (1.72%) and non-rhizosphere (1.82%) samples. In coarse clay humus complex, mean TOC was significantly higher in depleted fertility status (2.33%), Vertisol (2.71%) and rhizosphere (2.30%) samples, whereas for LC only significant difference was observed in soil. TOC showed significant and positive correlation with amorphous ferri-alumino silicate (AFAS) content and allophane content in fine and coarse clay humus complexes and allophane content in coarse clay humus complex. Fine clay humus in any soil is most important in terms of total amount of sequestered carbon. In coarse clay humus fraction, the role of Al and Fe compound is more prominent. Alfisol is the most potential soil for sequestering carbon; rhizosphere sequestered more carbon than non-rhizosphere.

Abstract: Three glaciers, namely Panchi-Nala, Zing-Zing-Bar and Baralacha-La in the Patsio region, Great Himalaya, India were monitored between 1971 and 2011 using satellite data. These glaciers were selected based on their terminus altitude, slope variations and debris cover. The Landsat, Corona, LISS-IV and Cartosat-1 satellite data were analysed to monitor variations in the area of glacier, terminus and annual snow line. Glacier outlines from the satellite imageries were generated using hybrid technique consisting of visual interpretation, band ratio, NDSII and thermal band (TM and ETM+) data. Glacier outline was also verified by GPS survey on Zing-Zang-Bar in 2011. The total loss in the area of a glacier terminus of 22.5 ma-1 was okbserved for the Zing-Zang-Bar glacier, wheras for Panchi-Nala and Baralacha-La glacier, the average retreat was observed to be 9.2 and 10 ma-1 respectively. An upward shift in Equilibrium Line Altitude was observed for all the glaciers between 1971 and 2011. The climate data collected at SASE meteorological station, Patsio (3800 m) between 1983 and 2011 suggests an increasing trend in the mean annual temperture and a decreasing winter precipitation. These observations support the effect of climate variability on spatial variation of glaciers in the Patsio region. Non-climatic factors such as size of the glacier, slope variation and debris cover were found to influence variable responses of different glaciers in the same climatic zone.

Abstract: Moisture uptake by plant roots from unsaturated soil is a key process for plant growth and transport of water in the soil-plant system. A soil water uptake model was developed and validated for non-uniform crop root zone in a sub-temperate, sub-humid agroclimate of Solan, Himachal Pradesh, India. Root water uptake function was incorporated in the governing soil moisture flow equation. A nonlinear root water uptake model developed earlier was selected as the base model to evaluate moisture extraction pattern in multilayer crop root zone and to evaluate its efficacy for the agro-climate of Solan. To validate the enhanced prediction efficiency of the model for a multilayer crop root zone, field experiments were conducted at the sub-temperate, sub-humid agro-climate of Solan under controlled condition on pea (Pisum sativum). Model predicted soil-moisture parameters, i.e. moisture depletion, moisture status at various depths and soil moisture profile in the root are satisfactory and in good agreement with experimental results. The model results indicate that the moisture uptake is more near the base of the root system. The resutls validated the utility of the root water uptake model across different agro-climates for non-uniform soils having different soil-moisture characteristics in different layers of the root zone. The model has demonstrated its applicability for accurate estimation of crop water requirement and helps in better irrigation scheduling and water management.

Abstract: Vegetable oil/animal fat is made up of one mole of glycerol and three moles of fatty acids, referred to as triglycerides. They differ in the nature of their carbon chain and the amount of unsaturation. They are highly viscous, water insoluble/ hydrophobic and contain larger fractions of free fatty acids apart from phospholipids, sterols, water, odourants and other impurities. These qualilties impede their direct use in engines and require modifications.

Abstract: With every sunrise, the world is being challenged to produce adequate food for its ever-growing population. Besides some inherent bottlenecks in agriculture, a basket of emerging problems has narrowed down the smooth pursuance of enhanced productivity. Among these, the burning issue of climate change and its possible consequences on agricultural production has recieved importance late, but the problem is very real. If nothing is done to seize or adapt to climate change, the situation will be harsh for us in the coming years. Agricultural productivity is a function of better inputs, among which quality seed holds utmost importance. Use of only 20-25% quality seeds, i.e. purchased new every year of total quality seed demand by Indian farmers makes it possible to produce about 260 mt foodgrains annually. So we can think of the production potential of high quality seeds. But, a steady temporal fluctuation in climatic variables has put seed quality under threat.

Abstract: Identification and mapping of crevasses in glaciated regions is important for safe movement. However, the remote and rugged glacial terrain in the Himalaya poses greater challenges for field data collection. In the present study crevasse signatures were collected from Siachen and Samudra Tapu glaciers in the Indian Himalaya using ground-penetrating radar (GPR). The surveys were conducted using the antennas of 250 MHz frequency in ground mode and 350 MHz in airborne mode. The identified signatures of open and hidden crevasses in GPR profiles collected in ground mode were validated by ground truthing. The crevasse zones and buried boulder areas in a glacier were identified using a combination of airborne GPR profiles and SAR data, and the same have been validated with the high-resolution optical satellite imagery (Cartosat-1) and Survey of India mapsheet. Using multi-sensor data, a crevasse map for Samudra Tapu glacier was prepared. The present methodology can also be used for mapping the crevasse zones in other glaciers in the Himalaya.

Abstract: The use of species distribution models is gaining popularity in biological sciences. We used Maxent, a Maximum entropy-based program, to predict distribution, we used field-collected coordinates of 177 presence locations of the species. Additionally, environmental data downloaded from the worldclim data portal were also used. Maxent was then run using default settings with 70% of the locations being used for training and the remaining 30% for testing the model. Area under curve for the receiving operator analyses measured at all possible threshold values training (0.993) and test (0.993) was close to 1, thereby showing the accuracy of the model.
