With 1.3 billion populaces on the commencement of the twenty-!rst century, India is currently impending toward upholding a subtle equilibrium between persisting social development and well-being without depleting existing biophysical resources at the national level or surpassing global average per capita obtainability. In this paper, we have struct...

Over the past few years, a growing number of scholars have explored environmental deterioration and its connection to various indicators acting as proxies for growth and globalisation. Taking this into view, the current study examines the globalisation-environment nexus, using 66 major countries and administrative regions of the Belt and Road Initi...

Sustainable Development Goal (SDG) index is a recognized metric for measuring progress in the UN SDGs. However, national or multinational-level analyses are more prevalent than sub-national types. We analysed the performance of 14 SDGs for 56 Indian cities (grouped into 6 regions) with available 77 indicators (2020-2021). Pearson’s correlation, hie...

The fulfilment of Sustainable Development Goal (SDG) 6, concerning water and sanitation, is critical in itself and also conditional for the other 16 SDGs being met. The purpose of this study was to understand the scientific research trajectories, spatiotemporal development, scientific collaboration, ongoing research themes, and gaps related to SDG...

The complexities associated with spatiotemporal delivery of drugs in disease therapy from the biomedical viewpoint, gradual increase in pollution level in the mother environment, and the quest for renewable energy sources as an alternative to the use of fossil fuels make it highly anticipated the development of technologies averting the therapeutic...

Globalization is embedded in socioeconomic development at the glocal scale (local to global). Drawing up from Kate Raworth’s Doughnut economics framework coupled with UN Sustainable development goals, we interrogate the relationship of globalization for socio-economic development (2000–2017). Here we have applied the Spearman correlation and data e...
Thesis
Full-text available
Agriculture (with industry and household sector) is one of three major sectors of human consumption in this Anthropocene era. For assessment of the sustainability of agricultural water resource consumption, various methods have been used to get insight into this dimension from multiple perspectives, such as - triple bottom line approach, planetary...

Socioeconomic achievement of WASH (access to safe water, sanitation and hygiene) services are being acknowledged as anticipatory actors, indispensable in safeguarding health during this Covid-19 pandemic. However, on a global scale, it is currently not clear whether deprivation or non-obtainability of which of the various WASH services are closely...

Objective: In this covid-19 pandemic, there is not very sound studies about the extensive socio-economic impact ushered with this disaster. The aim of this work is to understand thought of the youth, their opinion and understanding for various aspects of Covid-19 pandemic. Methodology: Using a combined qualitative-quantitative approach, Q method,...

Around the world, almost all countries have sought to stop the spread of the 2019 novel coronavirus (Covid-19) by lockdown and quarantine protocols, implemented from local to the national scale. For every scientific development and policy implementation which comprehensively connects this pandemic, the event is not very sound about the extensive so...
Presentation
In the Anthropocene, there is an urgent concern to save nature. Keeping aside the global-scale analysis of anthropogenic actions, assessments for local or regional scale systems are equally significant. In this preliminary work, for India, we have scoped how to select critical and iconic ecosystems based on their environmental role, socioeconomic d...

Abstract: Agriculture, along with industry and household sector are three major sectors of human consumption. Agriculture has proved to be a major contributor to exceeding planetary boundaries. Here, we have explored the impact of agriculture in the Earth system processes, through eight dimensions of planetary boundaries or safe operating spaces: c...

Abstract: With 1.3 billion populations, India is rushing to maintain balance between continuing social development and well-being without either depleting remaining biophysical resources at the national level or surpassing global average per capita availability. In this paper, we have structured a top-down per capita framework to explore national ‘...

The world is presently maintaining a delicate balance of continuing well-being and social development for the people through consumption of biophysical resources of nature without topping global average per capita availability. In this paper, we have framed a per capita top-down framework to survey national safe and just operating space (NSJOS) for...

Human endeavors to meet social and economic water needs at national scale might cause negative environmental manifestations and water stress from local to global scale. So, appropriation of Sustainable Development Goals requires a comprehensive monitoring and knowledge base of the water resource availability, utilization and access. Hence, scientif...

Agriculture is one of the most important drivers of increasing nine interlinked ‘Planetary Boundaries’ (PB) [viz. climate change, freshwater use, land system change, biogeochemical flows – especially Nitrogen and Phosphorus flows, ocean acidification, stratospheric ozone depletion, atmospheric aerosol loading, biosphere integrity and introduction o...

Flow of resource is the main character that facilitate a biological system to maintain its structure and functionality in accordance with interaction with abiotic system. Understanding this flow, at least at the very basic level, is the key towards understanding the total system. So far, all resource consumption appropriations are from anthropocent...

Abstract: Water consumption and pollution can be associated with specific activities. Freshwater is increasingly becoming a scarce global resource. Water footprint (WF) is an indicator of freshwater use that looks not only at direct water use of a consumer or producer, but also at the indirect water use. WF is regarded as a comprehensive indicator...
Presentation
Carbon footprints are important tool which allow quantification of carbon emissions & the associated activities that generate them. The definition of carbon footprint varies. Here, it refers to the quantity of GHG emissions directly or indirectly caused by operations of hostels (Wiedmann & Minx, 2007). In India, very little work have been performed...

Question
I have got the time series data (results) of mi, tc, pech and sech. How to elucidate these? How to correlate these with real world meanings?
Question
I have read that to get Real GDP, nominal GDP is to be divided by GDP deflator. However, if we get the GDP data with respect to one specific year, it can be assumed as Real GDP. So, to calculate the real GDP, what should be done?
1. Divide GDP (constant 2010 US$) by GDP deflator?
2. Divide GDP (current US$) by GDP deflator?
3. GDP (constant 2010 US$) can itself be used as Real GDP (without dividing it with GDP deflator)?
4. Any other solution and/or suggestions?
Question
Daily data are needed for all the states and union territories (UTs) of India from 01/01/2020 to as recent as possible.
Data needed of
1. Average temperature
2. Minimum temperature
3. Maximum temperature
4. rainfall (precipitation)
5. humidity
6. wind speed
7. air quality etc.
Question
I want to know how to create the specific 'planetary boundary' type image from data. Is this done via any specific software? If not, then how? I am attaching that image for reference.
Question
I need to correlate GHG emissions data (given in Gg CO2-equivalent or kt CO2-equivalent) with Climate Change Planetary boundary data (provided in t CO2) and put them into same unit.
