At the Root of Stubble Burning

Punjab is at the heart of India’s agricultural success story. Buoyed by the Green Revolution and favourable policy measures, the state contributes to 16% of India’s agricultural exports. The Agricultural Export Policy (AEP) of Punjab, notified in 2019, aims to more than double the value of its total exports of rice, wheat, and fruits from INR 14,000 Cr to INR 32,000 Cr by 2027–28, a staggering increase of 233%.

Waste Heat: An Overview

For millions of years before human activity, the extent of heat radiated away from the earth remained largely unchanged, thus ensuring global climate patterns remained stable. Lately, the effects of anthropogenic climate change have become increasingly obvious in the form of increased incidence of forest fires, icecap melting, and hurricanes. The drastic increase in the levels of greenhouse gases (GHGs) in the atmosphere due to the Industrial Revolution has reduced the level of heat radiated away, thereby retaining more heat within the global climate system.

Behavioural Shifts in the Transport Sector

Emissions from the Indian transport sector currently account for almost 10 per cent of the country’s total GHG emissions, mandating significant sectoral interventions for attaining the ‘net zero’ goal.

Strategies to reduce emissions from the transport sector include electric vehicle (EV) adoption, shift to public transport (PT), and non-motorised transport (NMT). These typically require substantial behavioural change.

Which Model to Choose? Performance Comparison of Statistical and Machine Learning Models in Predicting PM2.5 From High-Resolution Satellite Aerosol Optical Depth

The mathematical solution to estimate surface fine particulate matter (PM2.5) from columnar aerosol optical depth (AOD) includes complex variables and involves a bunch of assumptions. Hence, researchers tend to use training-based models to predict PM2.5 from AOD. Here, we integrated regulatory composite PM2.5 measurements, high-resolution satellite AOD, reanalysis meteorological parameters, and a few other auxiliary parameters to train ten different regression models.
