Study context. The . Drac. valley is located in the Western French Alps. The valley is located at the border of the Alpine glaciated area and was influenced by repeated base-level fluctuations due to glacial damming. This had led to repeated cycles of valley filling and re-incision, which potentially hold important information on the climatic control on fluvial and glacial dynamics in the region. Nuclear Institute for Agriculture and Biology (NIAB) played an effective role to learn. . to live with salinity and make profitable use of saline land and water resources. . . Initially screening for salt tolerance species were carried out and the scientists identified one salt tolerant variety of cotton (NIAB-999) and one salt tolerant variety of wheat (Sarsabz) for salt-affected areas. Two salt tolerant mutants, one each of mungbean & cowpea were developed and an early maturing cowpea mutant line was also identified that can tolerate salinity up to EC = 10 dS m.
