Bank filtration (BF) has emerged as an economical and sustainable water pre-treatment technology for drinking water supply. In this method, subsurface water of a water body moves into the well by seepage. BF wells adjacent to a river or lake pump the stored groundwater abstracted from the surface through aquifers. Chemical and biological contaminants such as turbidity, microbes, dissolved chemicals and natural organics are removed by the channel of aquifers present in the area. The whole process follows a series of physical, chemical and biological processes with some redox reactions. This study highlights the role of BF method in regulating water quality and quantity improvement. Besides, attempts have been made to discuss the mechanism, significance and the development of BF technology in the hilly state of Uttarakhand. Water quality status of Srinagar and Satpuli river BF sites of Uttarakhand are also described and compared with the Bureau of Indian Standards guidelines.Keywords

Amaranth is the common name for more than 60 different species of Amaranthus, which are usually 5-7 feet tall with broad green leaves and impressively bright purple, red, or golden flowers. It is said to be native of India and is most common summer leafy vegetable in the plains of Indian sub-continents. Three species Amaranthus cruenus, A. hypochondriacus, and A. caudatus are commonly grown for their edible seeds, while the A. tricolor L. and A. bilitum L. both are herbaceous annual grown for leaf purposes. Amaranth is a versatile warm-season, broad leaf plant that can be grown as a grain, ornamental, leafy vegetable, or forage crop. The seeds are high in lysine, fiber, and protein; low in saturated fats; and gluten-free. Amaranth can be ground into flour, popped like popcorn, or flaked like oatmeal. Because many of amaranth's uses are similar to that of cereal grasses, amaranth is often referred to as a pseudo-cereal. Products containing amaranth include breakfast cereals, granola, crackers, breads, cookies, and other flour-based products. The name for amaranth comes from the Greek amarantos, one that does not wither," or "the never-fading" true to form. Amaranth's bushy flowers retain their vibrancy even after harvesting and drying, and some varieties of ornamental amaranth forego the production of fancy flowers in favor of flashy foliage, sprouting leaves that can range from deep blood-red to light green shoot with purple veining. It isn't a true cereal grain in the sense that oats, wheat, sorghum, and most other grains are. "True cereals" all stem from the Poaceae family of plants, while amaranth (among others) is often referred to as a pseudo-cereal, meaning it belongs to a different plant species.References

Energy use in the rice–wheat crop production system is a major contributor to global greenhouse gas (GHG) emissions. Understanding input-wise energy flows in the production system is vital to optimize input–output and estimating GHG emissions and global warming potential. Doon Valley, India, has energy-intensive agriculture practices and a survey-based assessment was undertaken in this area covering 63 farms. According to the present study, rice and wheat production requires 63,825 and 50,799 MJ ha–1 of total energy input respectively. The main contributors were electricity, fertilizers and diesel for both crops; however, irrigation water was also a significant contributor in the case of rice. The yield per unit of energy use was relatively low which warrants better crop management practices to reduce the environmental footprint of the rice–wheat cropping system.References
