Energy use in the rice-wheat crop production system is a major emitter of global GHG emissions. Understanding of input-wise energy flows in the production system is vital to optimize input-output and also is essential to estimate GHG emissions and Global Warming Potential. Doon valley has energy-intensive agriculture practices and a survey-based assessment was undertaken in Doon valley covering 63 farms. The study estimated total input energy for rice-wheat cultivation as 63825 and 50799 MJha -1 respectively. Main contributors are electricity, fertilizer and diesel for both crops, however irrigation water is also a significant contributor in rice. The yield per unit energy use is relatively low and warrants better crop management practices to reduce the environmental footprint of the rice-wheat cropping system.

Site-specific topographic survey of 15 landslides located in the four mountainous states of India, namely Uttarakhand, Jammu & Kashmir, Sikkim and Nagaland was carried out through a Terrestrial Laser Scanner campaign. Versatility of the LiDAR instrument in topographic surveys and its advantages over conventional survey practices are highlighted. The effective use of the static Terrestrial LiDAR instrument in the rapid characterization and hazard assessment of landslides executed in this study is presented for adoption as a meaningful hazard assessment strategy in the hilly terrains arising due to landslides.

This study reviews groundwater status and management based on the existing literature regarding its resource endowment, hydrogeology, challenges and issues of management and policy suggestions for India. Efficient management requires decoupling groundwater rights from land-ownership rights, changes in electricity pricing and metering, aquifer-based plans for storage and replenishment, and empowerment of participatory irrigation management for local management. Issues of water–food–energy nexus, climate change, carbon footprint of groundwater extraction and virtual water trade are also important for ensuring sustainable management of groundwater resources.

A large volume of overlying waste material is removed to access deep-seated mineral deposits and stored near mines or eventually dumped as backfill. Overburden is stored in stacked dumps due to space constraints and high stripping ratios. The height and slope of these overburden dumps are enormous. This study is a parametric evaluation of the impact of interface and blast-ing-induced seismic loading on the stability of dump structures having total heights varying between 60 and 120 m. The study reveals that for 20 ° of internal friction of the interface, a factor of safety (FoS) of the slope structure increases with increasing cohesion (10–30 kPa). However, as the friction angle increases from 20 ° to 25 ° , the relative increase in FoS is reduced. Thus FoS remains unchanged with increasing cohesion for a friction angle of 29 ° . The stability of the dump reduces when subjected to blasting-induced seismic loading. The damage is more due to the shock waves imposing seismic loading in the horizontal direction than in the vertical direction.

: The lime works in India’s desert region were executed by a technique that is characteristically different from other parts of the country. The area is very hot and the high evaporation of water due to heat and less rain has caused salinity to the groundwater. Due to local climatic conditions, the decorative works of Rajasthan were executed on a shiny white plaster by a technique locally named Ala-Gila which is sometimes compared with the true fresco of Italy. The Persian colonial arts also flourished in this part and the color palette suddenly changed from vibrant to more shiny colors in the paintings. In this work, the microscopic observation of thin section was utilized to investigate geological and fine morphological features of the 16th century Amber fort lime plaster-a WHS site and a very popular tourist destination. The FTIR, XRD, and SEM photomicrographs of the plasters showed the stabilization of different crystalline phases of polymorphs of calcium carbonate. The chemical analysis and SEM-EDX data denote dolomitic limestone probably sourced for plaster works. The high amount of magnesium present in the raw material, the environmental conditions at the time of the application of the plaster, pH, etc. have stabilized calcite polymorphs in the plaster. The calcite meta-stable phases have undergone dissolution with time making the plaster weak. This has increased porosity, permeability, and resultant lowering of plaster's mechanical strength. The thermal analysis and cementation index of the plaster showed the use of non-hydraulic binder-rich air-lime for plaster works. The granulometric study showed the mixing of reddish-brown sand-size grains, and the aggregates were probably from the same location for major construction activity. The low proportion of aggregates led to reduced mechanical strength, and the is vulnerable to damage. It is to a major restoration of the ancient lime works with compatible materials as per analytical data

Most projects across the world are built under the public–private partnership (PPP) module. In the highway sector, the highway projects are built by the con-cessioner, and in lieu of that, he generates revenue by collecting tolls from road users. The toll plazas built across the highways to collect tolls act as a bottleneck in highway facilities. Although the toll collection system has been improved worldwide, users are still expe-riencing an enormous delay at toll plazas due to congestion, especially in developing countries like India. This congestion is caused due to various factors such as long service time, an inadequate number of windows, traffic volume, categories of toll rates, etc., which lead to delay, degradation of capacity, and level of service. Different researchers in their countries have analysed all these factors. The present article gives a detailed literature review summarizing various studies on the different parameters related to toll plazas and proposes research gaps from the perspective of developing countries. The challenges and methodology for evaluating various parameters are also discussed, and a way for-ward for future research is suggested.

The potential of a radio-sterilized host, Spodoptera litura (Fabr.), an established noctuid pest, was ascertained for in vivo transport of the viable entomopathogenic nematodes (EPNs), Steinernema thermophilum . Radio-sterilization (70 Gy) of the host (pest) was done to avoid any pest population build-up from the host larvae that could inadvertently miss EPN infection. The infective juveniles (IJs) derived from a radio-sterilized host took 67.3 h to induce host mortality, 132 h for incubation, and showed 87.8% parasitization with 98.9 IJs harvesting per mg host body wt, indicating almost similar parasitizing behaviour of these IJs as control. The findings indicated the suitability of the radio-sterilized host, S. litura , for carrying the IJs ( in vivo ) in a safe mode, that could retain a substantial degree of infectivity to be utilized in the field for managing this serious noctuid pest using biocontrol measures.

The archaeology of historical India has usually been perceived through the lens of cities and states, leaving forest tracts to a large extent unexamined. This article considers the historical signature in a segment of the Bandhavgarh National Park and Tiger Reserve, Madhya Pradesh, India, in order to understand how histories of occupation in jungles and wilderness where no settlements presently exist can be studied. Our survey involved a combination of ground-level investigations using GPS devices along with an analysis of satellite images to explore whether such images can be used for locating structures and sites. The earliest archaeological markers in Bandhavgarh are cave shelters of the 2nd century CE , which form the subject of this article.

North East India is a biodiversity-rich zone and a part of both the Himalaya and Indo-Burma biodiversity hotspots. It is a large-scale multipurpose landscape consisting of a mosaic of crops, livestock and forest. The landscape also ensures almost all the ecosystem services that con-tribute to the well-being of more than 100 diverse ethnic groups (indigenous people) in the region. However, in recent years, rapid transition in the form of promotion and expansion of oil palm and rubber plantations as mooted and supported by the state has posed threats to the ecosystem and biodiversity especially the biocultural landscapes. Supported by empirical evidence (primary and secondary data), this study argues that as we increase the intensity of production or harvest of such crops, the environmental cost becomes unprecedented and immense to be offset by economic gain. The use of renewable biological resources as the foundation for a bioeconomy must be regulated in terms of environmental impact ra-ther than short-term financial dividends. Therefore, we need to develop optimization models for the biocultural landscape(s) that determine land use based on what is both economically and environmentally optimal.
