Subject: Assessment of particulate matter in a university campus during spring season
Keywords: Air pollution, human exposure, particulate matter, spring season, university campus
Abstract: We aim to study particulate matter (PM) exposure at
university campuses. The campus of Banaras Hindu
University in the city of Varanasi was taken as a case
study. PM concentrations were recorded using a portable
aerosol monitor during peak hours for 45 days (February–March 2021) at several intersections inside the
campus. PM exposure was substantially higher during
the weekdays than on weekends. Due to higher humidity
conditions, PM2.5 (fine particles) exposure was higher
during February than during March. March witnessed
an increased PM10 (coarse particles) exposure because
of higher atmospheric temperature, which caused greater
resuspension of the coarse particles. PM concentration
inside the campus was affected by traffic volume, the
number of intersections, and the presence of speed breakers. PM2.5 (54 µg m–3
) was lower than the limits set by
the National Ambient Air Quality Standards in India
(60 µg m–3
). In contrast, PM10 (115 µg m–3
) exceeded
the standard limits (100 µg m–3
). Both PM2.5 and PM10
surpassed the daily limit (PM2.5: 15 µg m–3 and PM10:
45 µg m–3
) set by the World Health Organization
(WHO). Fine particulate matter (PM2.5) is more hazardous to health than coarse particulate matter (PM10).
Consequently, the air quality on the campus was moderate as per the national norms.

Subject: National geospatial policy: status of the Indian geodetic data
Keywords: Geospatial guidelines and policies, geoid model, horizontal and vertical positioning, topographic database
Abstract: The National Geospatial Policy has well communicated the need for sharing geospatial data, with
an emphasis that these data must refer to the geodetic/topographic database of the Survey of India
(SoI). SoI has been collecting, processing, archiving and disseminating geodetic data for over a century. Several stakeholders are using these datasets, viz. Government, academia, industry and researchers, for their respective applications. SoI also updated its database as and when required due to the
introduction of sophisticated and precise instruments, accuracy requirements, or to improve the database scientifically. Although the results or policies involving the geodetic data are provided in the
literature, there is limited discussion of the data themselves. This article provides comprehensive information about the geodetic data available to Indian users for various applications. The data discussed here are the horizontal and vertical positioning, gravity, geoid model and digital elevation
models.

Abstract: The Indian subcontinent formed when the
Indian landmass broke off from Antarctica
about 132 million years ago from the present (Ma) and collided with the Eurasian
landmass at 55 Ma. Understanding the process of the continental break-up between
Greater India and East Antarctica and the
evolution of early Cretaceous oceanic lithosphere has been difficult to comprehend
without ambiguity for a long time due to the
unavailability of an adequate volume of
geophysical observations from the conjugate rifted margins.

Abstract: Cows are the mainstay farm animal in
India’s dairy industry. In 2022–23, India
produced 221.06 million tonnes of milk, of
which 50% (110.5 million tonnes) was contributed by cows1
. Indigenous cattle breeds
such as Gir, Sahiwal, Tharparkar and RedSindhi play a significant role in Indian
dairy growth. The milk obtained from cattle
has enabled India to become the world’s
largest milk-producing nation. However,
the low productivity of indigenous cows
(3–4 kg per day) is a major challenge for
sustainable milk production. Globally, assisted reproductive technologies have produced quality animals. Among the several
reproductive technologies, animal cloning
can play a key role in faster multiplying elite
animals and the conservation of endangered breed.

Abstract: Rapid growth in human population last few decades has immensely increased pressure on natural resources like land, forest,wildlife and other natural resources for their basic need and livelihood.It has also reslted into elevation of population due to increased use of the motor vehicles, mining activities,factories, pesticides, fossil fuel and forest fire. Increased pollution has played significant role in climate change. Effects of global climate change suggest the future need for restoration of forest will increase (Stnturf et al., 2014).For the remedy to reduce this increasing pollution, forest vegetation can play vital role by their ability to store atmospheric carbon and to accumulate suspended particulate matter over their leaves.

Abstract: Forest ecological restoration is a vital step for climate change mitigation and maintaining biodiversity. It aims to recreate, initiate, or accelerate the recovery of an ecosystem that has been disturbed. However, forest monitoring and assessment of forest losses in the Himalayan region is a major challenge due to difficult terrain conditions recent advancements in Remote sensing and Geographic Information System (RS & GIS) techniques are enabling the quick and cost-effective solution for ecological restoration by mapping, monitoring, and quantification of areas that are affected due to degradation and deforestation. The present study aims to provide a review of recent advances in the methods and data products that can be used to extract information with regard to location, timing, and extent of vegetation losses and the past studies related to vegetation change conducted in the Garhwal region of Western Himalaya. The challenges and opportunities for the use of remote sensing in the field of restoration ecology have been discussed. The review revealed that there is very limited information available about the complex Himalayan ecosystem. Further research in the field of foret monitoring to assist t in early detection of degradation and formulation of area-specific ecological restoration techniques is needed.

Abstract: The study was undertaken with the objective to develop strategies for certification of wood and woodcraft products for Saharanpur District of Uttar Pradesh, India. The primary data was collected through h a preliminary survey from the various stakeholder including manufacturers and exporters, commission agents/brokers traders, and artisans. The data analysis relates to the awareness regarding wood certification among stakeholders, which indicates a very low level of that awareness among all stakeholders. Only 16.67% Commission agents 11.28% manufacturers and traders, 4.26% of traders are aware of the wood certifications 79.17% traders and 100.0% craftsman responded that they are not very much aware of the procedure and practices of wood certification. The majority of stakeholders are of the view that the role of non-government organization for wood certification which would work as a bridge between government and stakeholders. The share 97.74% of manufacturers and exporters answered that non-government organization creates awareness for wood certification and sustainable forest management. It was also revealed that the timber growers sustainable forest management. It was also revealed that the timber growers (Forest department and Farmers) should take initiative for certifying their wood rather than other stakeholders of the woodcraft industry.

Keywords: Nitrogen, Onion vegetables, Poplar, Agroforestry
Abstract: Agroforesty systems play a vital role in increasing the production of the crops that help to improve the financial status of the farmer. The experiment was laid out in a Randomized Block Design (Factorial) with three replications and 12 treatments with and without a combination of three onion varieties and different levels of nitrogen fertilizer. The experiment consisted of twelve treatments, viz. V1 +N0 kg, V1+N40 kg, V1+N 80 Kg. V1+N 120Kg, V2+N0 Kg, V2+N40Kg, V2+N80Kg, V2+N120Kg, V3+N0Kg, V3+N40Kg, V3+N80Kg, and V3+N120 Kg. The results revealed that leaf length was found superior at a 120 kg N/h fertilizer level (V1+N 120 Kg) in the onion variety Nasik Red. The onion variety Nasik Red was determined to be the best variety, and 120 kg N ha-1 was determined to be the optimum dose for achieving maximum onion leaf length in a poplar-based agroforestry system.

Abstract: Planted populations of indigenous fruit trees (IFTs) in the tropics may be the link towards efficient utilization and conservation of its genetic resources, but little is known of the genetic diversity they harbor. Tree bean (Parkia timoriana) is an economically important IFT that is cultivated and planted on and off farm in tropical regions of Northeast India. Using 3-microsatellite markers, the genetic variation and structure was compared of five-planted populations and a farmer-selected with three natural populations within northeast India. Pooled planted and selected populations showed marginal reduction in genetic diversity values compared to natural populations. Individually, cultivated populations from Manipur had higher Shannon diversity index (1=1.30 and 1.32) compared to wild populations (1=1.30, 1.08 and 1.12) .The farmer selected populations displayed appreciable level so diversity 9Na=5.33 and 1=1.12). Structure analysis revealed high degree of admixture in natural and two planted populations and PCA depicted close congruence with the geographical distribution of populations. The present study reveals that farmer driven selection process has not resulted to any major reduction in genetic diversity. There is ample diversity with natural as well as planted plantations of the species, which shall be crucial components for trait improvement in tree breeding programs.

Subject: Stand density and crown growth assessment of Anogeissus pendula Edgewin tropical Dry Deciduous Forests of Rajasthan (India)
Keywords: Structure, Density, Basal area, Height, Crown
Abstract: The present studies were carried out to assess the stand and crown growth of Anogeissus pendula Edgew.In the tropical dry deciduous forest at Jhalawar Forest Division, Rajasthan, India. The density of each site was determined by calculating the number of trees and basal area per hectares. The results revealed that the Mishroli(S1) performed highest for growth parameters viz, dbh(26.20 cm), height (11.65 m), basal area (17.2 m3/ha), volume (37.73 m3/ha) and crown height (2.48 m) with the lowest density (362.50 tree/ha), whereas , the minimum parameters has been observed at Bagher (S1) with the highest density (535 trees/ha) .The reverse is true for form factor (0.18) at the above sites. Performance at Mishroli (S3) has been attributed to lower density; trees of higher diameter class indicate site as having good site quality compared to others. However, the poor performance at S1 was attributed to a high level of disturbance observed in field. The crown level stand structure at S, reported good performance for the parameters viz., crown width (8.89m), crown length (9.46 m), crown basal area (63.62 m2/trees), crown index (1.07), crown per cent (80.79%) , crown surface area (149.18 m2/tree).In addition, the Crown projection ratio (44.99) and crown quotient to ground cover (3782.78) reported highest at Ghatoli (S4) and minimum (34.53) and 1213.02) at Mishroli (S3), due to high-density level causing low men dbh at S4 relatively to Mishroli (S3) .
