Abstract Investigating changes in terrestrial water storage (TWS) is important for understanding response of the hydrological cycle to recent climate variability worldwide. This particularly critical India where current economic development and food security greatly depend on its resources. We use 129 monthly gravity solutions from NASA's Gravity Recovery Climate Experiment (GRACE) satellites period January 2003 May 2014 characterize spatiotemporal variations TWS groundwater (GWS). The...

Abstract Recent heat waves have been a matter of serious concern for India because potential impacts on agriculture, food security, and socioeconomic progress. This study examines the trends variability in frequency, duration, intensity hot episodes during three time periods (1951–2013, 1981–2013 1998–2013) by defining based percentile maximum, minimum, mean temperatures. The also explores their relationships with hydroclimatic variables, such as rainfall, terrestrial water storage, Palmer...

ABSTRACT This study provides the comprehensive analysis of changes in mean and extreme temperature indices India to assist climate change mitigation adaptation strategies add information for global comparisons, using a high‐resolution daily gridded data set (1° × 1°) during 1971–2005. In addition recommended by World Meteorological Organization/ CLIVAR Expert Team on Climate Change Detection Indices, few more having social agricultural implication are investigated at seasonal annual scales,...

Abstract The patterns in groundwater level, rainfall and temperature extremes for the western Indian state of Gujarat were examined using water-table records 555 monitoring wells daily maximum data sets period 1995–2005. results reveal a large number declining trends levels with notable spatial structures; these are unlikely to be associated natural climate variability. There is also noticeable increase extremes. Our suggest that withdrawal has increased, perhaps due recurrent droughts...

Abstract Characterizing local to regional scale water cycles and resources will be crucial for achieving the United Nations' water‐related Sustainable Developmental Goals. However, quantification understanding of groundwater extraction across scales have been hampered by inadequate usage reporting limited information on irrigation practices. Here we analyze observations from ∼15,000 monitoring wells Gravity Recovery Climate Experiment satellites together with irrigation, agricultural,...

<title>Abstract</title> This study investigates the environmental and hydrological impacts of groundwater recharge structures constructed under Green Climate Fund (GCF) project between 2018 2024 in drought-prone regions Odisha, India. The research focuses on ten districts—Kalahandi, Keonjhar, Nabarangpur, Rayagada, Sambalpur, Subarnapur, Boudh, Balangir—characterized by water scarcity deteriorating vegetation health. Multi-temporal Sentinel-2 satellite imagery was analyzed using indices such...

An operationally easy and atom-economical approach for the regioselective tandem synthesis of functionalized 4-aminocarbazoles from easily accessible 2-alkynyl indole-3-carbonitriles under mild reaction conditions has been developed. The developed chemistry involves aza-Henry successive annulation to afford carbazoles. Replacement nitromethane with acetophenone led formation corresponding amino(phenyl)methanone-substituted carbazoles, further extending diversity chemistry. methodology...

This study examines the changes in monsoon rainfall of India using a suite extreme indices defined by Expert Team on Climate Change Detection Monitoring and Indices (ETCCDMI) to make Indian results comparable internationally, addition use some relevant particularly developed for climate. To this end, recently high resolution daily gridded (0.5° × 0.5°) dataset period 1971–2005 has been analysed robust nonparametric techniques. Despite interannual variability spatial diversity climatology,...

Abstract Understanding the key drivers behind intensive use of groundwater resources and subsequent depletion in northern India is important for future food security India. Although spatio‐temporal changes storage (GWS) its are mapped using NASA's GRACE (Gravity Recovery Climate Experiment) records, sub‐regional diverse socio‐political environmental factors contributing to variability withdrawals renewals not well documented. Here, we provide new evidence on GWS at different spatial scales...

An analysis of irrigation, agriculture, livelihood and poverty linkages in the districts Odisha has been carried out. District-wise scenario revealed with help different indexes developed. The values Groundwater Development Index have found low to very for 25 districts. Created irrigation potential out total ranged from 19 93 per cent kharif 8 61 rabi season. Half shown medium Agricultural values. Level living majority at level. About 60 BPL rural families comprise agricultural labourers,...

This study evaluates an over-exploited aquifer (Balasor, India) and also explores the possibilities of sustainable management using several statistical approaches. First, bootstrap analysis indicates that groundwater pumping has resulted in reduction mean cultivated area as average irrigation capacity per bore well dropped from 3.74 ha to 1.5 within a period 10 years operation. However, modelling levels seasonal autoregressive integrated moving (SARIMA) procedure showed no evidence...

Assessment of soil organic C (SOC) stocks is important for monitoring the effect land use change in cycle and formulation sequestration strategies context global climate change. Discrepancies among recent SOC estimates by different researchers underscore importance precise estimation uncertainty associated with stocks. A method was recently proposed to estimate storage using Taylor series approximations. Here we show that accuracy can be improved incorporating covariance input variables....

This study was carried out in farmers' fields to quantify the total water and consumptive use grow-out culture of Penaeus monodon under recommended package practice with two different management protocols: T1, no exchange T2, regulated exchange. Treatment-wise estimated use, 2.09 2.43 ha-m 122 day−1, while computed index (m3 kg−1 biomass) 5.35 6.02 T1 T2 respectively. Lower rates (T2) showed significantly improved (P < 0.05) crop performance terms (19.75 ± 0.75), production-size (74.1 3.4),...

This study was designed to quantify the total water requirement and consumptive use in carp-prawn polyculture system under different management protocols, using balance model. Under treatment-wise estimated use, TWU (×104, m3) 3.7, 4.6 3.9, while computed index, CWUI (m3 kg−1 biomass) 6.62, 9.31 7.08, T1 (no exchange), T2 (periodic exchange) T3 (regulated respectively. Significantly higher yield (P < 0.05) both over T1, probably due exchange that improved rearing environment. Although...

ABSTRACT In this study, the hydroclimatic variables of Orissa, a tropical region in eastern India, and cyclonic disturbances over Bay Bengal were analysed to assess trends variations using nonparametric statistical procedures.
