Droughts inflict significant loss on agricultural economies. Gomati River basin, the area of the present study, is located within the Ganga River floodplains, which approximately coincide with the north central temperature homogeneous region (NCTHR) of India. Gomati basin is a non‐perennial one supporting water intensive agricultural crops. To asce...

Uttar Pradesh is well known for its rice–wheat cropping system whenever it comes to agricultural sector. Being one of the highest producers of wheat and the second highest in terms of rice production, the state needs to be cautious about the usage of both of the quantity and quality of water as irrigation. The adversity of variability in climate ha...

With advancements in the science of simulation modelling, climate models have improved their projection capabilities. This can have an important bearing on the future hydrology of flowing surface waters in the current context of climate change.

Groundwater systems are largely influenced by rainfall variability which is considered the principal source of recharge. The present study explores the relation between the long-term rainfall (1992–2014) and the corresponding water table variation over the Varanasi district. The temporal trends of both the water table and long-term rainfall were an...

Present study evaluates the vegetation responses towards the rainfall variability in the Gomati basin during 1901- 2015. To accomplish the same, high resolution observed daily gridded rainfall data from India Meteorological Department (IMD) was analysed using non-parametric trend test. The long-term rainfall showed significant decreasing trend (α=0...

In the backdrop of the established fact that the climate and agricultural produce foster a close-knit relation, the present study explores the impacts of climate variability on the rice yields across diverse agro-climatic zones of Uttar Pradesh, India. The time-series non-parametric Mann-Kendall trend test was applied to study long term (both annua...

South Asia is vulnerable to a variety of hydrometeorological hazards, which are often crossboundary in nature. Climate change is expected to influence many of these hazards. Thus, climate-related risks over South Asia make disaster risk reduction (DRR) and climate change adaptation (CCA) key policy goals. Recently there is an increasing consensus th...

Sugarcane is a cash crop in Uttar Pradesh; economic condition of the farmers is highly dependent on sugarcane production. However, average yield of the state has gone up from 39.5 t/ha (1950-51) to 59.2 t/ha (2009-10), was observed associated with fluctuating weather conditions, whereas other major sugar producing area in India have average yield o...

In the wake of changing climate the present water crisis seems to tighten its hold on the Mankind hence water resources estimation is integral part of planning, development and management of water resources of the country and the estimation of water resource is based on several hydrological and meteorological parameters. Rainfall is the main source...

Rivers and river-valleys had been centres of development of civilisation. The importance of water as a precious resource had been realised by all civilisations to sustain life on earth. In ancient texts of India, it has been said, “where there is water, there is food; where there is food, there is life”. What was once a ubiquitous resource has beco...

The importance of climate has increased with the realization that climate change is not restricted to the Holocene or Pleistocene era but is a reality in a time scale that has affected present human civilization. Particularly extreme climatic events emphasize the importance of climate to society and demonstrate associated vulnerabilities. Anthropog...
