Keywords: Antimycin A, high temperature, membrane permeability, superoxide anion, Tritcum aestivum L.
Abstract: The act of antimycin A (AA) as an activator of the alternative respiratory pathway(AP) on the rate of superoxide anion (O2•-) generation and membrane permeability was studied in the functionally different organs of wheat seedlings (Triticum aestivum L) following short-term and long-term high temperature (HT).The results indicated a significant increase in the O2•- generating rate in etiolated wheat seedlings and seedlings grown under normal daylight regime following short-term ( 8% -37%) and long-term 13%-65 %) HT depending on the stage of development. The damages induced by HT were related to the permeability of membranes in the functionally different organs of wheat seedlings. However, our results demonstrated that increase in the O2•- generating rate in etiolated wheat seedlings was significantly lower following the combined effect of AA and HT, than under stressful conditions without AA. Take together, our observations show that the induction of AP, provoked by AA, prevents over-reduction of the mitochondrial electron transport chain, alleviating reactive oxygen species formation and protecting the etiolated wheat seedlings against oxidative damage.

Subject: Ecological status of areas awarded to tribals under Forest Rights Act 2006-a geospatial study of Adilabad Forest Division, Telangana, India
Keywords: Biodiversity, core area index, edge density, Forest Rights Act, Patch density
Abstract: Forest fragmentation and deforestation are major causes of biodiversity loss around the globe. Owing to high human and cattle population in India, the immense pressure on natural resources has led to greater degradation of natural ecosystems. The land-scape–level changes have in turn resulted in changes in species diversity and composition. Adilabad district has the largest proportion of forest area in Telangana, India. We studied the impact of land right awards granted under the Recognition of Forest Rights Act (RoFR), 2006 in the Adilabad Division. We hypothesize that the forest area awarded to the tribal under RoFR and illegal encroachment in forests have adversely impacted the forest biodiversity. To verify our hypothesis, we calculated edge density (ED), patch density (PD) and core area index (CAI) of all the Reserve Forest area using FRAGSTATS and compared the results with the pre-RoFR situation. Our results indicate that ED and PD increased predominantly across the Reserve Forest blocks where a large number of rights was granted under to RoFR, whereas CAI decreased. Statistically for all the three parameters, pre-and post-RoFR have a significant adverse impact on the forests. Our findings are consistent with our hypothesis, and indicate that the continued use of forest areas for agriculture in RoFR and encroachment areas may further adversely impact the ecosystem. There is an urgent need to identify and implement conservation actions that would allow restoration of biodiversity of the Reserve Forest areas adversely affected by land rights awarded under RoFR. Measures such as aggregation of the scattere RoFR areas towards the Reserve Forest boundary and improved agricultural practices such as agroforestry may alleviate such adverse impacts.

Subject: Wildlife conservation through Corporate Social Responsibility initiatives in India
Keywords: Corporate social responsibility, corporate, protected areas, wildlife conservation
Abstract: In India, the concept of corporate social responsibility (CSR) has always been embedded in the tradition of philanthropy and has focused on education, health and religious activities. Through the introduction of Companies Act 2013, these efforts are being institutionalized through a framework for taking up defined activities and spending limit. With 869 protected areas covering 165, 088.36 sq.km (5.02% of the total geographic area), India is one of the mega-biodiverse countries in the world, and requires substantial capital and efforts to conserve and manage the wide arrary of wildlife it holds. This study has employed secondary data analysis to highlight the activities adopted by the corporate towards wildlife conservation. It is observed that only a handful of companies are committed to supporting wildlife under CSR. Given the relatively large ecological footprint of companies, it becomes more binding on them to contribute with a modest investment to overall prospects of biodiversity conservation that can bring substantial economic and reputational benefits to them, and at the same time bring the much-needed support and funds for the conservation cause. The Act provides an excellent framework for engaging the corporates in identifying the conservation needs and fulfilling their responsibility towards nature.

Subject: Aerobic granular sludge: the future of wastewater treatment
Keywords: Activated sludge, aerobic granulation, sequencing batch reactor, wastewater treatment
Abstract: Water, food and energy security are interlinked and central to sustainable development. Wastewater is a key element in the water-food-energy nexus, and recovery of resources can link water, nutrient and energy cycles. Effective treatment of wastewater is essential for public health and sanitation, water reclamation, preventing environmental pollution and protecting water resources. Furthermore, the treated wastewater is essential for public health and sanitation, water reclamation, preventing environmental pollution and protecting water resources. Furthermore, the treated wastewater is a potential resource and its reuse will partially offset supply and demand in water-stressed areas. A century-old activated sludge (AS) process is still widely employed, though not sustainable in terms of large land footprint, higher costs and complex designs for achieving biological nutrient removal. The recently developed aerobic granular sludge (GS) process is a better replacement for AS and promises sustainable wastewater treatment for atleast the next century. The GS process uses familiar sequencing batch reactor technology for simultaneous removal of organic carbon, nitrogen, phosphorus and other pollutants from wastewater. Among the available biological treatment options, GS process is the most preferred choice because of smaller land footprint, lower costs and effective wastewater treatment. Accumulating research shows that the GS technology has gained enormous popularity; it is increasingly considered for capacity extension as well as new wastewater treatment plants in domestic and industrial sectors.

Abstract: India does not have a clear stand on the release and consumption of genetically modified crops (food).The only approved crop is Bt-cotton, which has put India on the global map as a cotton exporting country. Even so, Bt, brinjal is under moratorium and GM mustard is prevented from undergoing commercial trial. All these decisions are not based on sound scientific principles. Activism against has successfully prevented exploitation of a powerful technology that can contribute to India’s food and nutrition security. This article attempts to give a balanced perspective of genetic modification technology as one of the serious options to be considered on case to case basis. Ambivalence will seriously affect India’s food security in the future.

Keywords: Granitoids, magmatic epidote, oxygen fugacity, shear zone emplacement
Abstract: Magmatic epidotes of granitoid pluton from North Purulia Shear Zone, eastern India, are identified by textural and chemical criteria. The accessory sphene, epidote, allanite and magnetite in the granitoid indicate high f02 during crystallization. Hornblendes were crystallized between 1.2 and 4.8 kbar, 753°C and 783°C as well as high f02 (>Ni-Nio buffer). Preservation of magmatic epidote in pluton emplaced at low pressure is due to rapid magma ascent (>3.1 km/year). Fast upward transportation of parental magma of the pluton took place through extensional voids along the regional shear zone.

Keywords: Agro-ecological sub regions, agricultural development, characterization and mapping, doubling farmers’income.
Abstract: Prioritizing and targeting less developed regions is one of the multi-pronged strategies for doubling farmer’s income (DFI) in India. Using an indicator approach, the present study assessed and mapped agro-ecological sub-regions (AERs) based on ten indicators representing production, infrastructure, information, marketing and income of the farmers. On the basis of the composite index of agriculture development. AESR 9.1 and AESR 1.1 were found to be the most and the least developed regions respectively. Further, the potential districts for each of the less-developed AESRs have been identified for greater prudency in planning. The study concludes that for achieving the target of DFI within the stipulated time-frame, it is imperative to mainstream AESR-based planning in technological development and dissemination. The evidences revealed large and equitable response of the efforts targeted towards less-developed regions.

Subject: Bleaching stress on Indian coral reef regions during mass coral bleaching years using NOAAOISST data
Keywords: Bleaching threshold, degree heating week, mass coral bleaching, sea surface temperature
Abstract: Coral reefs are one of the most ancient, highly productive marine bio-diverse ecosystems on earth. They are threatened to collapse under rapid climate change. ENSO is an extreme climate change event which elevates sea-surface temperature (SST) of tropical oceans. This elevated SST increases the level of thermal stress on coral reefs. Also, coral reefs are the most sensitive among all ecosystems due to temperature change; they exhibit bleaching when SST exceeds normal summer maxima and remains high for more than 28 days. Bleaching threshold, positive SST anomaly and degree heating week (DHW) are commonly used indices for calculating thermal stress on coral reefs. The major coral reef regions in India are Andaman, Nicobar, Lakshadweep, Gulf of Mannar and Gulf of Kachchh.SST from NOAA OISST v2 high-resolution daily dataset at 0.25° global grids from 1982 to the present was used for the present study. Here, we focus on the variations in SST experienced by Indian coral reef regions during known mass coral bleaching (MCB) years, viz.1998, 2010 and 2016.The year 2010 recorded the highest thermal stress for Andaman, Nicobar and Gulf of Kachchh regions, and the year 2016 was severe for Lakshadweep and Gulf of Mannar regions. In 2010 Nicobar was observed to be the most vulnerable according to DHW index.

Abstract: Solid –to-water proportion decides the effectiveness of paste backfill in terms of transportation characteristics during mine backfilling. This article highlights various laboratory tests conducted to determine the optimum solid-to-water ratio. Also, numerical simulation was carried out using computational fluid dynamics technique (ANSYS FLUENT) to understand the slump lifting process and variation in volume of the paste with time. The optimum slump and spread for lead-zinc mill tailings paste were in the range 190-200 mm and 330-340 mm respectively. The optimum water content in the paste fill for this study was found to be 23 wt % .Results shows that the solid percentage is inversely related with slump and spread. Also, an optimum slump lifting speed needs to be maintained for accurate values of slump and spread.

Subject: Individual borrowing and default behaviour in surplus and constrained credit environments: evidence from India
Keywords: Behaviour, borrower, constraint, credit terms, surplus
Abstract: The present article studies borrowing behaviour between credit surplus and credit constrained environments in the context of microfinance, with respect to rural borrowing. Surplus and constrained environments get defined based on the number of the state-promoted self help groups (SHGs) in the district, and the volume of credit disbursed through these SHGs. Four hundred nineteen respondents comprising of farmers, off-farm workers, farm labourers, small businesspersons, SHG members and chit-fund or cooperative members were interviewed in the surplus district of Chittoor and the constrained district of Nalgonda in the erstwhile state of Andhra Pradesh. Statistical analyses comprising of OLS, binary logistic regression, ANOVA, t-test and chi-square tests show that surplus environments offer more adverse credit terms especially for farmers and farm labourers. Further, surplus causes over-borrowing and defaults. Constraint propels planned repayments. Both the environments offer varying credit terms across trades. We also observe better lending terms when farmers and traders are among lenders in a constraint environment. Interlinking factor markets like land, labour and capital in a constrained environment leads to efficient outcomes, reinforcing the theory of New Institutional Economics.

Keywords: Agroforestry, economics, intercropping, land equivalent ratio, poplar
Abstract: There is widespread use of poplar in pulp and paper , match splints, pencil and plywood industries, in northern India. The practice of closer spacing geometry with compact block in poplar cultivation does not permit intercropping from the third year onwards, which discourages small landholders. In 2008, poplar was planted at the Chaudhary Charan Singh Haryana Agricultural University, Hisar, India in three spacing geometries of 5x4m, 10x2 m, and 18x2x2m (paired row) at a constant density of 500 trees ha-1.In the present study, two cropping rotations (sorghum-the present study, two cropping rotations (sorghum-berseem and cowpea-wheat) were intercropped in all three spacing geometries of poplar (up to eight years of rotation), and compared with sole cropping as a control. The results showed that yield of annual crops reduced considerably over the years due to enhancing competition for light, moisture and nutrients. The overall yields of annual crops in various spacing geometries of poplar were reduced by 5.67 % in the second year to 45.59 % in eight years of plantation. The study resulted in 10 x 2 m spacing of poplar with sorghum-berseem crop rotation exhibiting the highest net returns (Rs 1, 191, 241ha-1), NPV @ 12 % discounting (Rs 409, 673 ha-1) , B:C ratio (1:2.22) , IRR (70%) , highest land equivalent ratio (2.28) and land expectation value (Rs 2, 242, 372 ha-1).In the study, LER and LEV calculated to increase the efficiency and adoptability of agroforestry systems. Therefore, on the basis of economics, the present study concludes that the intercropping of sorghum-berseem and cowpea-wheat in poplar planted at a spacing of 10 x 2 m is more profitable and helpful in doubling farmers’ income over traditional agriculture in northwestern India.

Keywords: Advance warning system, disaster management, floods, governance, policy planning
Abstract: Floods in the Indian subcontinent have affected habitat, population, economy, etc. due to the detrimental effects of recent floods on the economy, governance, etc., it is imperative to understand the associated dynamics, manifestations and fallouts for proper policy planning recommendations. The present study endeavours to provide an integrated rationale of meteorological and geomorphological aspects associated with four recent extreme floods in Uttarakhand (2013), Srinagar (2014), Chennai (2015) and Gujarat (2017). It is important to mention here that these floods occurred under different atmospheric circulations and geomorphological setting and had an entirely different gambit for policy planning and governance. Consolidation of these issues will help policy planners and technologists, in case advance warning system based on these findings can be developed.

Abstract: Throughout the tropics, growing human population, overexploitation and endangerment of biological resources are leading to habitat loss of flora and fauna, and in turn loss of biodiversity. In this context, the need for intensive in situ conservation measures, both at regional and global scale, has been stressed. However, due to various anthropogenic activities, such measures alone may not be always effective and feasible. Hence, apart from in situ conservation, ex situ conservation and mass propagation of plants are important not only to conserve but also to sustainably utilize these resources.
