The purpose of this study is to analyze variations in wheat yields and to assess the range of factors affecting wheat yields and profitability of wheat production in the selected irrigation systems in India and Pakistan. The study attempts to identify constraints and opportunities for closing the existing yield gaps. It is hypothesized that substantial gains in aggregate yields can be obtained by improved water management practices at the farm and irrigation-system levels.

This paper reviews the complex impact of climate change on gender relations and associated vulnerability on the Eastern Gangetic Plains of Nepal and India. Field research has identified that gendered vulnerability to climate change is intricately connected to local and macro level political economic processes. Rather than being a single driver of change, climate is one among several stresses on agriculture, alongside a broader set of non-climatic processes. While these pressures are linked to large scale political–economic processes, the response on the ground is mediated by the local level relations of class and caste, creating stratified patterns of vulnerability. The primary form of gendered vulnerability in the context of agrarian stress emerges from male out-migration, which has affected the distribution of labour and resources. While migration occurs amongst all socio-economic groups, women from marginal farmer and tenant households are most vulnerable. While the causes of migration are only indirectly associated with climate change, migration itself is rendering women who are left behind from marginal households, more vulnerable to ecological shocks such as droughts due to the sporadic flow of income and their reduced capacity for investment in off-farm activities. It is clear that policies and initiatives to address climate change in stratified social formations such as the Eastern Gangetic Plains, will be ineffective without addressing the deeper structural intersections between class, caste and gender.

The present study dealt with understanding hydrogeochemical evolution, ascertaining distribution, fate and spatio-temporal variation of arsenic along with comprehending recharge processes and quantification of recharge rate in the central Gangetic plain, India. The arsenic enriched area was observed mostly in the fluvial deposits with younger alluvium. The depth to water levels maps for 1996 and 2016 showed marked spatio-temporal variation and the groundwater recharge rate was estimated to be varied between 0.05 m/year and 0.07 m/year in the study area. The elevated arsenic concentration was noticed in the region, having declined groundwater recharge. A total of 147 water samples were collected from hand pumps (n = 141) and rivers (n = 6) during the pre-monsoon period (May 2016). In addition, about 81 groundwater samples were collected from 27 locations during the pre-monsoon, monsoon and winter 2019 for studying seasonal variability in the hydrogeochemical parameters and isotopic composition of water. Arsenic concentration was found more in the area where deposits of coarser sediment of the Quaternary period was present along the rivers Ganga and Ghaghra. The arsenic concentration was observed higher in the pre-monsoon (maxm. As 641 µg/L), followed by the post-monsoon (425 µg/L) and monsoon season (375 µg/L). The depleted isotopic value and higher D-excess values in groundwater suggested active recharge conditions with precipitation as the major source of recharge in the study area. It is hypothesized that rainwater induced oxygenated water into the aquifer by the process of recharge, which may prompted various biogeochemical reactions due to change in redox conditions and endorsed arsenic sorption in the monsoon season. Thereafter, anoxic conditions prevailed in the post-monsoon season, and finally, in the pre-monsoon season, reducing conditions continued and arsenic released at a rapid rate, which was justified with the seasonal variation of arsenic concentration.
