ECOLOGICAL STATUS AND IMPACT OF DISTURBANCE IN AN ALPINE PASTURE OF GARHWAL HIMALAYA, INDIA

The alpine area in Garhwal Himalaya is highly fragile and is known for its beautiful flora and fauna. The study area was located just below the Gangotri glacier which is the origin of Bhagirathi, a holy river of India. Pilgrimage, tourism, adventure activities and mules are the factors responsible for causing disturbance in this area. There is a remarkable variation in the values of diversity, species richness, dominance, density IVI and biomass production at Bhojbasa Protected (BP) and Bhojbasa Disturbed (BD) sites. The value of liveshoot biomass was highest in August (444 g m-2 on BP and 80 g m-2 on BD sites). Belowground biomass was also recorded highest for BP site and lowest for BD site. The ANP value at BP site was 363 g m-2 y-1 and 26 g m-2 y-1 at BD site.This area has shown decrease in diversity and productivity, and heavy soil erosion that indicate the consequence of increasing human activities due to pilgrimage, tourism and camping and frequent movement of mules carrying goods. Therefore, this area requires strict measures for biodiversity conservation and disaster mitigation

Forest structure, diversity and regeneration potential along altitudinal gradient in Dhanaulti of Garhwal Himalaya

Aim of the study: The aim of the present study was to understatnd the forest composition, structure, diversity and regeneration potential along altitudinal gradient.Area of study: The study was carried out in Dhanaulti forest which falls under temperate region of Garhwal Himalaya in Uttarakhand state, India.Material and Methods: Vegetation analysis was carried out using 10 quadrats at each altitude using a quadrate size of 10×10 m2. In each quadrate, categories of trees >30 cm cbh were considered as trees, 10-30cm cbh as saplings and <10 cm cbh as seedlings. The data were quantitatively analyzed.Main results: In upper and middle altitudes, Cedrus deodara was reported dominant tree whereas, in lower altitude Quercus leucotrichophora was reported dominant. Tree density was highest in lower altitude which reduced middle and upper altitudes whereas, total basal cover increased with increasing altitude. The increasing total basal cover with altitude could be because of the presence of Cedrus deodara trees having higher girth classes. In tree, sapling and seedling layers, diversity (H) and equitabiltiy (EC) decreased with increasing altitude. However, concentrations of dominace (CD) and beta diversity (BD have shown reverse trend with H and EC which increased with increasing altitudes, in each layer of tree, sapling and seedling.The distribution pattern of most species in all layers of trees, saplings and seedlings was contagious. The regeneration potential of the species has shown that some of the species in the absence of tree layer are still regenerating particularly, Rhododendron arboreum, Benthamidia capitata, Neolitsea pallens etc. It indicates that most of the species are shifting upward as they are getting suitable conditions.Research highlights: Altitude influence species composition, diversity and regeneration potential of species.Key words: Distribution pattern; tree diversity; regeneration; mountains; temperate; Himalaya.

Income support programmes for the older adults in South Asia:a scoping review protocol

INTRODUCTION: South Asian countries are ageing and experiencing a rapid increase in proportion of the older population. Income support programmes are of central importance for the older adults as they may help to mitigate the poverty risks associated with ageing and losing the ability to generate income from labour. Evidence related to the income support programmes can help in understanding whether the programmes have been impactful. This scoping review will map the evidence (and gaps) related to income support programmes and create a base to identify the feasibility of future primary research and/or the scope of systematic reviews in the areas where evidence is available. METHODS AND ANALYSIS: The Joanna Briggs Institute scoping review methodology will be followed. Eligibility criteria for the scoping review will be based on the ‘PCC’ or the ‘Population–Concept–Context’ concept. Advanced search for the relevant articles will be conducted in MEDLINE (via PubMed), Embase, Scopus, Campbell Collaboration, 3ie International Initiative for Impact Evaluation and Web of Science. Additional resources search will be conducted in important organisational websites. Findings of the scoping review will be summarised using descriptive information (frequencies and percentages) for the available evidence on concept (ie, income support programmes), population characteristics and other study variables. ETHICS AND DISSEMINATION: The review is based on data from available literature, hence an ethical approval is not necessary. With this review, we attempt to provide recommendations to the research community and the policymakers about the currently available evidence and the research required for income support of older adults in South Asia, so that resources can be directed towards addressing the same. We plan to disseminate the findings through presentation in international conference and publication in a peer-reviewed journal. REVIEW REGISTRATION: Not registered

The utilisation of systematic review evidence in formulating India's National Health Programme guidelines between 2007 to 2021

Evidence informed policymaking integrates the best available evidence on programme outcomes to guide decisions at all stages of the policy process and its importance becomes more pronounced in resource constrained settings. In this paper, we have reviewed the use of systematic review evidence in framing National Health Programme (NHP) guidelines in India. We searched official websites of the different NHPs, linked to the main website of the Ministry of Health and Family Welfare (MoHFW), in December 2020 and January 2021. NHP guideline documents with systematic review evidence were identified and information on the use of this evidence was extracted. We classified the identified systematic review evidence according to its use in the guideline documents and analysed the data to provide information on the different factors and patterns linked to the use of systematic review evidence in these documents. Systematic reviews were mostly visible in guideline documents addressing maternal and newborn health, communicable diseases and immunization. These systematic reviews were cited in the guidelines to justify the need for action, to justify recommendations for action and opportunities for local adaptation; and to highlight implementation challenges and justify implementation strategies. Guideline documents addressing implementation cited systematic reviews about the problems and policy options more often than citing systematic reviews about implementation. Systematic reviews were linked directly to support statements in few guideline documents, and sometimes the reviews were not appropriately cited. Most of the systematic reviews providing information on the nature and scale of the policy problem included Indian data. It was seen that since 2014, India has been increasingly using systematic review evidence for public health policymaking particularly for some of its high priority NHPs. This complements the increasing investment in research synthesis centres and procedures to support evidence informed decision making, demonstrating the continued evolution of India's evidence policy system

The Atomic Manifesto: a Story in Four Quarks

This report summarizes the viewpoints and insights gathered in the Dagstuhl Seminar on Atomicity in System Design and Execution, which was attended by 32 people from four different scientific communities: database and transaction processing systems, fault tolerance and dependable systems, formal methods for system design and correctness reasoning, and hardware architecture and programming languages. Each community presents its position in interpreting the notion of atomicity and the existing state of the art, and each community identifies scientific challenges that should be addressed in future work. In addition, the report discusses common themes across communities and strategic research problems that require multiple communities to team up for a viable solution. The general theme of how to specify, implement, compose, and reason about extended and relaxed notions of atomicity is viewed as a key piece in coping with the pressing issue of building and maintaining highly dependable systems that comprise many components with complex interaction patterns

Integration of organics in nutrient management for rice-wheat system improves nitrogen use efficiency via favorable soil biological and electrochemical responses

IntroductionThe contrasting soil management in flooded-transplanted rice (Oryza sativa) and dry-tilled wheat (Triticum aestivum) poses a challenge for improving low nitrogen use efficiency (NUE) of the rice-wheat system. Integration of organics in nutrient management can bring in changes favoring efficient N uptake via changes in growing conditions and soil responses.Materials and methodsThis study reported the results of a 15-year-long experiment on integrated nutrient management (INM) systems for rice-wheat cropping. The INM included substituting ~50% of chemical fertilizers via (i) including a legume crop (Vigna radiata) in the sequence and its biomass incorporation (LE), (ii) green manuring with Sesbania aculeata (GM), (iii) farmyard manure application (FYM), (iv) 1/3 wheat stubble in situ retention (WS), and (v) 1/3 rice stubble in situ retention.Results and DiscussionThe INM strategies resulted in improved NUE compared to 100% chemical fertilizers (F). The INM had significantly higher net N mineralization and improved biological activity aligning with the NUE trends. The reductions in redox potential (Eh) and pH during rice season improved NUE under integrated management. Highly reduced conditions favored N mineralization and plant availability in form of NH4+−N resulting in enhanced uptake efficiency, in rice crop. The soil organic carbon (C) significantly increased in INM, and an effect of the active C fractions was evident on the NUE of the wheat crop.ConclusionThe results showed that these INM strategies can immensely benefit the rice-wheat system via improvement in biological health along with electrochemical changes for flooded rice, and labile-C-assisted improvement in soil conditions for wheat
