Keywords: Random thoughts, 100 most cited papers, 1925 to 2008.
Abstract: Critics notwithstanding, citations seems to have gained a golden currency status in contemporary research. Among the 58 million items collected in the Thomson Reuters ' Web of Science database, 100 of the most cited papers up to 7 October 2014 were presented in Nature last year. I presented an analysis of the most cited papers such as: (1) how many of the 100 ranked papers were sole authored or double-authored; (2) distribution patterns of these papers along the decades, between 1925 and 2008, and (3) cited number of references in83 o the accessible ranked papers. Thirty-one among the 100 most cited papers were sole-authored. Nine science Nobel laureates (Frederick Sanger, Walter Kohn, Roger Tsien, Erwin Neher, Bert Sakmann, Kary Mullis, Oliver Smithies, Georges Kohler and Cesar Milstein) have authored eight of the most cited papers.

Abstract: Maize (Zea mays L.) commonly known as corn has wider adaptability under varied agro-climatic conditions. It is cultivated on nearly 150 m ha in about 160 countries. In India, maize is the third most important food crop after rice and wheat. Globally, maize is known as the queen of cereals, because it has the highest genetic yield potential among cereals. Maize was domesticated by indigenous peoples in central Balsas valley of Mexico around 9000 years ago. Until Columbus introduced corn to Europe, it was not grown outside the Americas. The evolution of corn is a matter of controversy among scientists. Several theories have been proposed about the specific origin of maize, including the most prevalent theory of direct domestication of a Mexican annual teosinte, hybridization between a small domesticated maize (a slightly changed form of wild maize) and a teosinte, undergoing two or more domestications either of a wild maize or of a teosinte and evolving from the hybridization of Zea diploperennis by Tripsacum.

Abstract: Clean Development Mechanism (CDM) is one of the most flexible mechanisms under the Kyoto Protocol (KP) for project-based emission reduction activities in developing countries that aim to generate certified emission reductions (CERs).Although Afforestation/Reforestation-Clean Development Mechanism (A/R-CDM) is a small part of the overall CDM, such projects have helped in the sustainable development of degraded and unproductive land. In most cases the benefits from these projects have flown to the participating communities. After the successful completion of the first commitment period of the KP, India has managed to register 7 A/R-CDM projects between 2008 and 2012 and currently holds 18 % of the share in the international carbon market (ICM).Now with the commencement of the second commitment period, and with India having ample scope for carbon mitigation options though the land use, land use change and forestry (LULUCF) activities, our farmers should seriously think of using this mechanism as a tool to gain financial benefits apart from the role in carbon offsetting. The opportunities in the ICM should be seriously tapped by such farmer groups whose lands are not giving sufficient dividends to them.

Abstract: Dhanya and Arun Kumar have presented a schematic of interlinking of factors influencing estimation of environmental flow (Eflow), wherein the Eflow is computed first accounting for the water quality and quantity issues and finally, the minimum flow is computed based on the current and future scenarios of water quantity and quality. This schematic reveals that minimum flow is equal is equal to the dilution factor times E-flow, and is not the same as the E-flow, which has to be prescribed to maintain the river water quality standards. However, in their study, the terminologies ' minimum flow ' and ' Eflow ' are used interchangeably. Based on our past experience, particularly with the estimation of Eflows for some of the hydropower projects in India, it is argued that there is a significant difference between these two terminologies.

Abstract: Biobeds, also called biofilters, are facilities intended to retain and degrade as well as facilitate microbial breakdown of on-farm pesticides. Point sources of pollution, especially when filling spraying equipment for pesticides in farmer ' s field can be minimized using biobeds. A major point source of contamination is spills during filling and cleaning of spraying equipment. These activities often are performed at particular on-farm sites due to the convenience of water supply. Spraying equipment is normally filled in the same place on the farm every time, often in the farmyard near water sources. Due to these activities, high concentrations of pesticide residues have been found at on-farm sites. A low-cost system known as the biobeds can minimize the risks of such pollution.

Abstract: With 356 million, 10-24 year olds, India has the largest young population in the world, according to a report issued by the United Nations. Education is thus essential for the future of the country. However, according to the Census of India, 2011, 7.8 crore families in the country use kerosene as a primary source of lighting. Many school-going students who study during evening hours are affected by either lack of access to alternate source of lighting or by erratic electricity supply. Alongside Right to Education, therefore, it is desirable to provide the ' Right to Light ' as well.

Abstract: India is blessed with abundant solar energy. Solar drying systems are now being used for agro-industrial applications. SPRERI forced-flow cabinet-type solar dryer has been in regular operation in an industry named M/s Jayveer Food Industry located at Chanashma in district Patan, Gujarat, since 2010.The solar drying system comprises flat plate solar collectors connecting air ducts and a blower for supply of hot air to three drying cabinets. A batch of fresh produce (approximate Moisture Content is 90 per cent) loaded in to the dryer in the morning got dried only partially by the end of the first solar day, and the drying operation, in general, continued for the second day to achieve the desired result from the product. The quality of the product, which was left overnight in drying cabinet under ambient conditions, was affected due to microbial growth. Besides, moisture condensation also takes place in the drying cabinet. The industry was also interested in enhancing the output by extending the drying cabinet. The industry was also interested in enhancing the output by extending the drying operation beyond solar hours. A SPRERI biomass combustor-cum-air heater was successfully retrofitted with the solar drying system for completing batch drying operation by the same day. The-solar-biomass drying system is in operation in the industry for more than a year now.

Abstract: The slurry emanating from the biogas plant is referred to as biogas plant spent slurry (BSS).It is rich in nitrogen(N), phosphorus (P), potassium (K) and several micronutrients. The content of these plant nutrients varies, depending on the type and nature of feedstocks used for production of biogas. The digested slurry discharged from the conventional biogas plants normally contains 92-94 per cent moisture where as in the case of solid state biogas plants; the moisture content varies between 88-90 per cent. BSS is one of the potential sources of nutrients for organic farming but it is practically difficult to supply the entire nutrient demand of crops with BSS because of its bulky nature. To reduce bulkiness, enrichment of BSS with nutrients using organic (e.g., biofertilizers) and mineral sources (e.g., rock phosphate) is an attractive option for its use in organic farming practices.

Abstract: Conservation of biodiversity has been put to the highest priority throughout the world. The process of identifying threatened ecosystems will search for different drivers related to biodiversity loss. The present study aimed to generate spatial information on deforestation and ecological degradation indicators of fragmentation and forest fires using systematic conceptual approach in Telangana state, India. Identification of ecosystems facing increasing vulnerability can help to safeguard the extinctions of species and useful for conservation planning. The technological advancement of satellite remote sensing and Geographical Information System has increased greatly in assessment and monitoring of ecosystem-level changes. The areas of threat were identified by creating grid cells (5 x 5 km) in Geographical Information System (GIS).Deforestation was assessed using multi-source data of 1930, 1960, 1975, 1985, 1995, 2005 and 2013.The forest cover of 40, 746 km2, 29, 299 km2, 18,652 km2, 18, 368 km2, 18, 006 km2, 17, 556 km2 and 17, 520 km2 was estimated during 1930, 1960, 1975, 1985, 1995, 2005 and 2013, respectively. Historical evaluation of deforestation revealed that major changes had occurred in forests of Telangana and identified 1095 extinct, 397 critically endangered, 523 endangered and 311 vulnerable ecosystem grid cells. The fragmentation analysis has identified 307 ecosystem grid cells under critically endangered status. Forest burnt area information was extracted using AWiFS data of 2005 to 2014.Spatial analysis indicates total fire-affected forest in Telangana as 58.9 % in a decadal period. Conservation status has been recorded depending upon values of threat for each grid, which forms the basis for conservation priority hotspots. Of existing forest, 2.1 % grids had severe ecosystem collapse and had been included under the category of conservation priority hotspot-I, followed by 27.2 % in conservation hotspot-II and 51.5 % in conservation priority hotspot-III. This analysis complements assessment of ecosystems undergoing multiple threats. An integrated approach involving the deforestation and degradation indicators is useful in formulating the strategies to take appropriate conservation measures.

Abstract: The invasion of alien species is a significant threat to global biodiversity and the top driver of climate change. The present study was conducted in the Great Rann of Kachchh, part of Kachchh Biosphere Reserve, Gujarat, India, which has been severely affected by invasion of Prosopis juiflora.The invasive weed infestation has been identified using multi-temporal remote sensing datasets of 1977, 1990, 1999, 2005 and 2011.Spatial analyses of the transition matrix, extent of invasive colonies, patchiness, coalescence and rate of spread were carried out. During the study period of three and half decades, almost 295 km2 of the natural land cover was converted into Prosopis cover. This study has shown an increment of 42.9 % of area under Prosopis cover in the Great Rann of Kachchh, part of the Kachchh Biosphere Reserve during 1977 to 2011.Spatial analysis indicates high occupancy of Prosopis cover with most of the invasion (95.9 %) occurring in the grasslands and only 4.1 % in other land cover types. The process of Prosopis invasion shows high patch initiation, followed by coalescence, indicating aggressive colonization of species. The number of patches within an area of <1 km2 increased from 1977 to 2011, indicating the formation of new Prosopis habitats by replacing the grasslands. The largest patch of Prosopis cover increased from 144 km2 in 1977 to 430 km2 in 2011.The estimated mean patch size was .8 km2 in 1977.The mean patch size was largest during 2011, i.e., 9 km2.The annual spread rate for Prosopis has been estimated as 2.1 % during 2005-2011.The present work has investigated the long term changes in Prosopis cover in the Great Rann of Kachchh, part of Kachchh Biosphere Reserve. The spatial database generated will be useful in preparing strategies for the management of Prosopis juliflora.

Abstract: Forest fire has been identified as one of the key environmental issue for long-term conservation of biodiversity and has impact on global climate. Spatially multiple observations are necessary for monitoring of forest fires in tropics for understanding conservation efficacy and sustaining biodiversity in protected areas. The present work was carried out to estimate the spatial extent of forest burnt areas and fire frequency using Resourcesat Advanced Wide Field Sensor (AWiFS) data (2009, 2010, 2012, 2013 and 2014) in Andhra Pradesh, India. The spatio-temporal analysis shows that an area of 7514.10 km2 (29.22% of total forest cover) has been affected by forest fires. Six major forest types are distributed in Andhra Pradesh, i.e. Semi-evergreen, moist deciduous, dry deciduous, dry evergreen, thorn and mangroves. Of the total forest burnt area, dry deciduous forest account for >75 %.District-wise analysis shows that Kurnool, Prakasam and Cuddapah have shown >100 km2 of burnt area every year. The total forest burnt area estimate covering protected areas ranges between 6.9 and 22.3 % during the study period. Spatial burnt area analysis for protected areas in 2014 indicates 37.2 % of fire incidences in the Nagarjunasagar Srisailam Tiger Reserve followed by 20.2 % in the SriLankamalleswara Wildlife Sanctuary, 20.1 % in the SriVenkateswara Wildlife Sanctuary and 17.4 % in the Gundla Brahmeswaram Wildlife Sanctuary. The analysis of cumulative fire occurrences from 2009 to 2014 has helped in delineation of conservation priority hotspots using a spatial grid cell approach. Conservation priority hotspots I and II are distributed in major parts of study area including protected areas of the Nagarjunasagar Srisailam Tiger Reserve and Gundla Brahmeswaram Wildlife Sanctuary. The spatial data-base generated will be useful in studies related to influence of fires on species adaptability, ecological damage assessment and conservation planning.

Abstract: Monitoring of forests has gained vital recognition in the international scenario due to realization of its role in carbon sequestration, biodiversity and global warming. Through advancement of remote sensing and GIS technology it is possible to monitor and analyse gross and net changes in forest ecosystems .This article analyses the deforestation rates and drivers of deforestation in India and summarizes the Government initiatives for conservation of forests based on the published literature. It also reviews gross and net rate of deforestation from the national level to locale scale. At the national level, Forest Survey of India has been carrying out mapping of forest cover on a biennial basis. The current estimate of gross deforestation in India is quite low (-0.43 %) for 2009-2011 compared to the global average of -0.6 %. Even though considerable progress has been made in the protection of forests, gross deforestation rate continues as a focal hindrance. The deforestation studies carried out in various parts of India are found to be fragmentary and far from being comprehensive .From the regional analysis carried out, it can be seen that the overall net rate of deforestation was relatively high in the North East region (-0.90to -5.29) and Deccan Peninsula (-0.19 to-3.2) followed by the Western Ghats. For precise estimation of gross and net deforestation, consistency in definitions, uniform methodology and new techniques for quantifying forest cover have been realized.

Abstract: Analyzing the spatial extent and distribution of forest fires is essential for sustainable forest resource management. There is no comprehensive data existing on forest fires on a regular basis in Biosphere Reserves of India. The present work have been carried out to locate and estimate the spatial extent of forest burnt areas using Resourcesat-1 data and fire frequency covering decadal fire events (2004-2013) in Similipal Biosphere Reserve. The anomalous quantity of forest burnt area was recorded during 2009 as 1,014.7 km2.There was inconsistency in the fire susceptibility across the different vegetation types. The spatial analysis of burnt area shows that an area of 34.2 % of dry deciduous forests, followed by tree savannah, shrub savannah, and grasslands affected by fires in 2013.The analysis based on decadal time scale satellite data reveals that an area of 2, 175.9 km2 (59.6 % of total vegetation cover) has been affected by varied rate of frequency of forest fires. Fire density pattern indicates low count of burnt area patches in 2013 estimated at 1, 017 and high count at 1, 916 in 2004. An estimate of fire risk area over a decade identifies 12.2 km2 is experiencing an annual fire damage. Summing the fore frequency data across the grids (each 1 km2) indicates 1,211 (26%) grids are having very high disturbance regimes due to repeated fires in all the 10 years, followed by 711 grids in 9 years and 418 in 8 years and 382 in 7 years. The spatial database offers excellent opportunities to understand the ecological impact of fires on biodiversity and is helpful in formulating conservation action plans.

Abstract: Forest fragmentation is considered as one of the major conservation issue. The purpose of this study is to contribute to the understanding of the national assessment of spatial patterns of forest fragmentation and influence of deforestation on fragmentation in the Indian forests during three decade interval (1975-2005).Mapping of forest cover was carried based on Landsat MSS and IRS P6 AWiFS data using hybrid classification techniques on 1:250, 000 scale. The present study considered biogeographic zones as a major stratum formation level assessment. The forest fragmentation was analysed based on landscape indices which allow quantification and categorization of complex forest landscapes and depict landscape composition, structure and scenario of fragmentation. The analysis revealed that in all biogeographic zones, more than 90% of total number of forest fragments consists of patches having area less than 1 km2.At national level the mean forest patch size stands at 187 ha. The total core area was highest for islands (87.4 %) followed by Eastern Himalayas (82.5 %), Deccan (78.9 %), Deserts (76.4 %) and Eastern Ghats (76 %). The temporal analysis shows that the loss of Indian forest areas as 5.8 % during 1975-2005.The annual rate of deforestation has been computed as 0.20 % at national level. The decreased mean patch size, increased edge density and increased number of patches from1975 to 2005 indicates ongoing fragmentation in biogeographic zones. The very high fragmentation in Trans Himalayas is contributed mostly by the natural factors while in other biogeographic zones; increased fragmentation is due to deforestation.
