This paper by the International Food Policy Research Institute (IFPRI) reviews the success of zero-tillage wheat in the rice-wheat systems of the Indo-Gange

The level of nitrate in drinking water was tested from groundwater artesian wells located within farms and surrounded by crops (mostly rice and wheat rotations).

Nitrate pollution in groundwater is associated with nitrogen loads in the environment. In urban areas, it is associated with sewage and in agriculture areas, with livestock sources and nitrogen fertiliser inputs. Nitrate pollution in drinking water can have serious health impact on humans, especially for babies and children. The most significant potential health effects of drinking water contaminated with nitrate are the blue-baby syndrome (methemoglobinemia) and cancer.

This paper in Current Science attempts to establish a missing stream link between the Markanda river and the Vedic Saraswati river in the plains of northern Haryana based on geoelectrical resistivity surveys. Resistivity surveys in the Gangetic Plains around Pehowa region in Haryana, have revealed different subsurface geological formations composed of fine, medium and coarse sand with gravel. Resistivity section between the lower part of the Markanda basin and the Saraswati river around Pehowa region indicates the presence of buried sand bodies connecting the two rivers.
