“…As discussed in the costbenefit analysis section, in some of the villages, costs of increasing irrigation may outweigh benefits of doing so. In addition, returns to investment in irrigation may be lower when other factors are taken into account (Jaglan and Qureshi, 1996). 12 One such factor is the negative impacts of irrigation on environment.…”

The overall goal of our paper is to understand the impact that irrigation in China has had on grain production and incomes, in general, and income and poverty alleviation in poor areas, in particular. The paper seeks to meet three objectives. First, we describe the relationship among irrigation status, yields and household crop revenue. Second, we seek to understand the magnitude and nature of the effect that irrigation has on yields and crop revenue. Finally, we seek to understand the impact that irrigation has on incomes in poor areas. Our analysis shows that irrigation contributes to increases in yields for almost all crops and in income for farmers in all areas. The importance of crop income in poor areas and the strong relationship between crop revenue and irrigation provides evidence of the importance of irrigation in past and future poverty alleviation in China. We also show that in the majority of the villages that invested in new irrigation, returns are positive even after accounting for increases in capital and production costs.

“…Studies carried out in the irrigated area of the lower Ganga canal in Uttar Pradesh by Umar and Sami Ahmad (2000) shows that groundwater's in this area have a residual alkalinity (Ca 2+ < HCO − 3 ) and 50% of the samples have a pH in excess of 8.2. Further the study carried out by, Jacks et al (2005), Jaglan (1996) and Kumar (1996) shows that soil pH and alkalinity in Rajasthan has been increased. Moreover the area irrigated by the Indira Gandhi Canal has rapidly rising groundwater levels and low-lying parts show rising pH due to water logging (Jaglan and Qureshi 1996).…”

Large scale emigrations from rural areas to urban areas and population growth have been uninterrupted and accelerating phenomena in parts of Ganga basin, where urbanization is increasing at an unprecedented rate. Urban agglomeration is causing radical changes in groundwater recharge and modifying the existing mechanisms. Majority of the cities are sited on unconfined or semi confined aquifers depend upon river water and groundwater for most of their water supply and disposal of most of their liquid effluents and solid residues to the rivers and ground. There has also been an inevitable rise in waste production. Drainage of surface water has been disrupted as the small natural channels and low lying areas have been in filled, often with municipal waste. Total water potential of the Ganga basin including surface water potential and ground water potential is around 525.02 km 3 and 170.00 km 3 respectively. Basin supports approximately 42% of the total population in India. Water tables are declining at approximately an average of 0.20 m per year in many parts of the basin and there is a trend of deteriorating groundwater quality. The demand of water has been increased many folds and most of the areas are highly reliant upon the groundwater to meet this increasing demand for water, but unfortunately degradation of groundwater both in terms of quantity and quality has deteriorated the situation. Studies shows that change in climate may increase temperature by 2 to 6 • C and can reduce precipitation up to 16%, which could reduce the groundwater recharge by 50%. In densely populated Ganga basin urban drainage consumes a high proportion of the investments into urban infrastructure and needs integrated approach for the sustainable development of water management, water education regarding conservation and pollution caused by urbanization.

“…Groundwater salinity is directly linked to soil salinity and both are caused by evaporation, dissolution of evaporates, waterlogging, groundwater level rise, excessive usage of water in irrigation practices, industrial wastewater discharge, dumping sites, etc. (Jaglan and Qureshi 1996;Meena 2001;Raju et al 2009;Misra 2011;Nandimandalam 2012;Khan et al 2015).…”

Groundwater quality receives increasing attention in water management in India. The purpose of this paper is to highlight the emerging issues of groundwater quality in the Ramganga Sub-Basin (RSB), a tributary joining the Ganga River from the northern plains, which extends over 30,839 Sq. km and covers 15 districts in both Uttarakhand and Uttar Pradesh. The groundwater in most of the districts of the RSB has high concentration of nitrate, iron, salinity and fluoride, which exceed the standards prescribed for drinking water by the Bureau of Indian Standards (BIS) and World Health Organization (WHO). Arsenic contamination in groundwater is an emerging issue in few groundwater development blocks. Moreover, groundwater with substantial hardness, high sulfate, and high manganese is emerging issue in some districts. Additionally, shallow aquifers have high concentration of ions. In the RSB, the quality of groundwater, especially in the shallow aquifers, is influenced by the contamination of poor quality surface water, due mainly to poor sanitation, improper disposable of domestic sewage water, manures and irrigation return flows. To reduce deterioration of water quality further, the RSB requires proper sanitation facilities, efficient usage of agrochemicals, as well as an awareness program of water-related disease
