At a Russian Academy of Science meeting in March, Vladimir Yakunin, the 66-year-old head of Russian Railways, unveiled detailed plans for what may seem like an impossible infrastructure project. Yakunin proposed engineers could build a high-speed railway through the entirety of Siberia, dubbed the Trans-Eurasian Belt Development (TEPR)—the final destination of which would be the mouth of an underwater tunnel crossing the Bering Strait. Highway, too, could be constructed adjacent to the tracks, effectively making ground transportation possible from Anchorage to Moscow—or for that matter, New York to Paris.

In cultivation of crops, irrigation is very very important for the growth and development of plants. Every grain crop needs a lot of water for the absorption of nutrients as well as for making food through photosynthesis. Optimum irrigation produces high yield of crops which leads India to achieve the goal of self sufficiency in food crops so irrigation is very necessary for the higher yield of crops.
