Short affidavit on behalf of the Rajasthan State Pollution Control Board (RSPCB) in terms of the National Green Tribunal order dated January 22, 2025. The application was registered suo motu by the NGT on the basis of a news item titled "Toxic kilns pollution Aravallis; wildlife and locals suffer" appearing …
The purpose of this study is to propose the Bayesian Network (BN) model to estimate flood peak from Atmospheric Ensemble Forecasts (AEFs). The Weather Research and Forecasting model was used to simulate historic storms using five cumulus parameterization schemes. The BN model was trained to forecast flood peak from AEFs. …
Glaciers in the Satluj river basin in western Himalaya are likely to lose 33% of their area by 2050 and 81% by the end of the century, under Representative Concentration Pathway - RCP 8.5 scenario, based on the output from CNRM-CM5 and GFDL-CM3 climate models respectively. Original Source
The Zimbabwean government has warned that the 2018-19 agricultural season will be a tough one with farmers having so far failed to adequately make land preparations and to plant crops because of erratic rains throughout the country. Besides the season setting in late, many parts of the country have received …
This paper investigates the impact of exposure to extreme temperature on crop yields of a range of crops cultivated in the State of Karnataka, India. The crops examined in this study are rice, sorghum (jowar), finger millet (ragi), and pigeon pea. We use a taluk-level fixed effects panel data model …
The present study was undertaken with aim to understand the perceptions of indigenous communities about climate change pattern and its local impacts on climate variables, seasons, agriculture, biodiversity and adaptive strategies in geographical and technological-isolated Pangi valley situated in Chamba district, Himachal Pradesh. Randomly selected 120 respondents were interviewed and …
Despite the lack of robust empirical evidence, a growing number of media reports attempt to link climate change to the ongoing violent conflicts in Syria and other parts of the world, as well as to the migration crisis in Europe. Exploiting bilateral data on asylum seeking applications for 157 countries …
Megacities are predominantly concentrated along coastlines, making them exposed to a diverse mix of natural hazards. The assessment of climatic hazard risk to cities rarely has captured the multiple interactions that occur in complex urban systems. We present an improved method for urban multi-hazard risk assessment. We then analyze the …
Southern Africa is expected to receive erratic rainfall in the 2018/19 agricultural season, according to the latest outlook produced by regional climate experts, who have predicted that seasonal rainfall will be "normal to below-normal" across most of the region. The consensus forecast produced by the 22nd Southern African Regional Climate …
The study finds that between 4,500 and 3,000 years ago, strong winter monsoons were characterised by “early neoglacial anomalies (ENA)” — changes in wind and precipitation patterns that are evident across the eastern Northern Hemisphere and tropics. A new study suggests that climate change may have led to the decline …
Nagpur: Rising air pollution in India is likely to have a significant impact on long-term rainfall patterns which can cause extensive financial losses, warns the latest United Nations report. ‘Air Pollution in Asia and the Pacific: Science-based Solutions’ presents the first scientific assessment of air pollution in Asia and the …
The 2015/2016 El Niño event caused severe changes in precipitation across the tropics. This impacted surface hydrology, such as river run-off and soil moisture availability, thereby triggering reductions in gross primary production (GPP). Many biosphere models lack the detailed hydrological component required to accurately quantify anomalies in surface hydrology and …
Agriculture is one of the sectors that has greatly benefitted from the establishment of climate services. In Colombia, interannual climate variability can disrupt agricultural production, lower farmers' incomes and increase market prices. Increasing demand thus exists for agro-climatic services in the country. Fulfilling such demand requires robust and consistent approaches …
Flooding is one of the major natural disasters from a storm event that is prevalent in many countries and greatly affects river morphology, modifying the flora and fauna of a given river environment. As a consequence of climate change, the probability of frequent floods and drought is acute in the …
The social cost of carbon (SCC) is a commonly employed metric of the expected economic damages from carbon dioxide (CO2) emissions. Although useful in an optimal policy context, a world-level approach obscures the heterogeneous geography of climate damage and vast differences in country-level contributions to the global SCC, as well …
Extreme climate events such as droughts and heat waves exert strong impacts on ecosystems and human well-being. Estimations of the risks of climate extremes typically focus on one variable in isolation. In this study, we present a method to examine the likelihood of concurrent extreme temperature and precipitation modes at …
Hydropower is a valuable renewable energy resource in India, which can help in climate change mitigation and meet the increasing energy demands. However, the crucial role of climate change on hydropower production in India remains unexplored. Here using the observations and model simulations, we show that seven large hydropower projects …
In summer (pre-monsoon) of recent years, low water level among the last few decades, has been observed in several lower Indian reaches of the Ganges (or Ganga) river (with estimated river water level depletion rates at the range of −0.5 to −38.1 cm/year between summers of 1999 and 2013 in …
This paper presents future climate and runoff projections for the South Asia region under the RCP8.5 scenario with climate change informed by 42 CMIP5 GCMs. Runoff is projected for 0.5° grids using hydrological models with future climate inputs obtained by empirically scaling the historical climate series.

The carbon and water cycles play an important role in ecosystem functioning and are linked to each other through different physical and biological processes. The hydroclimatic disturbances such as droughts affect both hydrological as well as the ecological processes. Increasing hydroclimatic disturbances under climate change will adversely affect the ecohydrological …
Human-induced environmental and climate change are widely blamed for causing rapid global biodiversity loss, but direct estimation of the proportion of biodiversity lost at local or regional scales are still infrequent. This prevents us from quantifying the main and interactive effects of anthropogenic environmental and climate change on species loss. …
