Research Highlights

The study identifies three prominent heat wave (HW) prone regions i.e., Northwestern, Central and South-Central India, and found a Spatio-temporal shift in the occurrence of HW events with a significantly increasing trend, highest being in West Madhya Pradesh (0.80 events/year), while a significantly decreasing trend was observed over eastern region i.e., Gangetic West Bengal (-0.13events/year). Severe Heat wave (SHW) events showed a southward expansion and a spatial surge during the decades of 2001-2010 and 2010-2016. Additionally, correlation between HW/SHW events and observed mortality reveals that the eastern coastal states i.e., Odisha and Andhra Pradesh show a significant positive correlation of 0.62 and 0.73 respectively.

The evidence of effect of multiple air pollutants e.g., aerosols (black carbon, BC; PM2.5 and PM10) and trace gases (NO2, SO2 and O3) on all-cause premature mortality was established over central Indo-Gangetic Plain (IGP). Statistically significant impact of BC aerosols (4.95%), followed by NO2 (2.38%) and PM2.5 (1.06%) on mortality was noted, particularly for elderly and children. Individual effects of air pollutants increased in presence of other pollutants. The distributed lag nonlinear model showed significant lag effect of pollutants up to 5 days. The exposure-response curves for individual air pollutants were mostly linear.

IAerosol climatology during typical haze dominating period was explored using several EOS products from 2010 - 2020. Comparatively high aerosol loading with dominance of fine and UV-absorbing aerosol are noted across the Indo-Gangetic plain (AOD:0.58; UVAI:0.74) against weak UV-absorbing fine aerosols over Southeast Asia (AOD:0.26; UVAI:0.07). Urban hotspots across IGP (except Dhaka) denote a spatially consistent minor increasing trend in AOD (0.2-1.8x10-2year-1) while increase in UVAI is more prominent over upper IGP. Smoke aerosols are more UV-absorbing across South Asia compared to Southeast Asia. At upper atmosphere (>4km) dust aerosols clearly dominate across the IGP. Smoke & urban aerosols are abundant over SEA.

Smoke injection height varied considerably during rice (October-November: 0.71±0.65km) and wheat (April-may: 2.34±1.34km) residue burning period with a significant positive correlation with prevailing boundary layer. Besides, despite travelling efficiently to free troposphere, major proportion of smoke AOD (50-80%) continue to remain close to the surface (less than 3km).

Increasing trend of DTR (0.038_C/decade) during 1951–2016, and a decreasing trend (−0.02_C/decade) during the recent period (1991–2016) across the different agro-climatic zones (ACZs) of India. Increasing trend was noted for Tmax (0.078_C/decade, significant), Tmin (0.049_C/decade) during 1951–2016 and Srad (0.10 MJ/m2/day/decade) during 1984–2016. Decreasing trend in DTR was accounted for much increase in Tmin (0.210_C/decade) during 1991–2016. There were also interesting spatial differences found with the ACZs in the north-west, parts of Gangetic plain, north-east, and central India exhibiting negative DTR trends.

It is the first study to evaluate performance of eight CORDEX-SA regional climate models for simulating heat waves over India. In the present study, Regional Climate Models (RCMs) namely, CCAM and RegCM, from Coordinated Regional Climate Downscaling Experiments (CORDEX) for South Asia (SA) are evaluated for simulating heat waves (March–June) over India in comparison with observations from India Meteorological Department (IMD). LMDZ4 and GFDL-ESM2M were found to be best-performing models in significantly reproducing the heat wave frequency and spatial variability in closer proximity with observations over India amongst all models after bias correction. The study suggests a way forward to assess RCMs performance in extreme weather analysis in future projections.

The performance and validation of regional climate model (RegCM-4.3) simulation of Indian summer monsoon rainfall (ISMR) have been conducted with a futuristic view of climate change study with the convective parameterization schemes (CPSs) over the different homogeneous regions of India. Performance and validation of RegCM-4.3 in capturing regionalized rainfall of Indian subcontinent was assessed and various best performing parameterization schemes of RegCM-4.3 were identified to simulate the rainfall over different regions of India. The overall diversification of simulation depending upon the topographical difference of Indian subcontinent causes the regionalize difference in simulating monsoon rainfall over the Indian subcontinent.

Impact of climate change on sugarcane crop was assessed using the CANEGRO-Sugarcane model in diverse agro-climatic zones of the Uttar Pradesh. The results showed that Stalk Fresh Mass is projected to increase by 3–39% (rainfed) and 7–47% (irrigated) in 2040–2060 relative to 1971–2000. Similarly, Sucrose Mass is projected to decrease by 9–69% (rainfed) and 6–37% (irrigated). The findings suggest the development of efficient water use, heat-tolerant cane variety and improved farm management strategies in the near future to assist the sugar industry and to adapt to the changing climate in northern India.

Conclusive evidence of the negative impact of rising temperature on wheat yield was reported for India. The impact was inconsistent spatially. One degree increase in mean temperature resulted a 7% decrease in wheat yield over India which varied disproportionally across the wheat growing zones within a range of -9% (peninsular zone, PZ) to 4% (northern hills zone, NHZ).

Increase in daily mean temperature was strongly associated with excess mortality in Varanasi, both during summer (5.61%) and winter (1.50%). Daily mortality was found to be increased by 12% due to heat wave. The study is first to present the increase in mortality with decrease in diurnal temperature variation. Increase in mortality was high during summer compared to winter. Similarly, risk ratio was high due to heat wave compared to cold spell.

As soil erosion is an integral element for sustainable agricultural and environmental development, this study aims to investigate the impact of rainfall and land use/land cover changes in the current and future scenarios (1981 – 2040) to further deduce the soil erosion losses using the state-of-the-art Revised Universal Soil Loss Equation (RUSLE), Cellular Automata Markov Chain (CA-Markov) and machine learning models. In total seven CMIP5 model projections viz Ensemble mean, MRI-CGCM3, INMCM4, canESM2, MPI-ESM-LR, GFDL-ESM2M and GFDL-CM3 of rainfall were used in model development and comparison. As a result, we have generated an integrated framework for the prediction of soil erosion rates over Mahi River Basin.

A comprehensive evaluation of multi-satellite satellite precipitation products are undertaken against ground-measured Indian Meteorological Department (IMD) precipitation data to estimate and forecast the meteorological drought in the Bundelkhand region of Central India. The high-resolution CHIRPS data showed the closest agreement with the IMD precipitation and well captured the drought characteristics. The Standardized Precipitation Index (SPI) identified seven major droughts events during the period of 1981 to 2016. The forecasting result showed a reasonably good agreement with the observed datasets with the one-month lead time.

We assessed the existing status and scope of DRR including CCA in development projects across South Asia, so that an effective and achievable deliberation may be made to regional policymakers. The project inventory was diverse in nature with respect to location, scale, sectoral focus, and strategic importance. Bangladesh, India, and Bhutan were found to be proactive in implementing DRR- and CCA-related projects. Meta-analysis suggests an urgent need for an individual and collaborative convergence of processes for DRR and CCA through policies, plans, strategies, and programs.

This work aims to explore the biasness in the RegCM climate model outputs for diverse agro climatic zones of Uttar Pradesh, India emphasizing on wheat and rice yields with and without bias corrected data for the baseline period of 1971–2000. Bias correction approach showed good agreement for the annual and seasonal maximum and minimum temperatures. The CERES-Wheat and CERES-Rice models embedded in DSSAT (Decision Support System for Agro-technology Transfer) were used to quantify the biasness in the simulated potential, irrigated, and rainfed wheat and rice yield. The RCM-simulated wheat and rice yield were high while the bias-corrected yield has shown good agreement with the observed yield.
