in agreement with significant expansion of agricultural activities in the Deccan Chalcolithic cultural period. Mineral deposits The Godavari River basin is endowed with rich mineral deposits such as oil and gas, coal, iron, limestone, manganese, copper, bauxite, granite, laterite, and others. The following are the few noted deposits: Araku hills, bauxite Godavari Valley Coalfield, coal Bailadila iron, iron Krishna Godavari Basin, oil & gas Malanjkhand, copper MOIL, manganese Pench Kanhan Coalfield, coal Rowghat Mines, iron Wardha Valley Coalfield, coal Ecological concerns The frequent drying up of the Godavari river in the drier months has been a matter of great concern. Indiscriminate damming along the river has been cited as an obvious reason. Within Maharashtra sugarcane irrigation has been blamed as one of the foremost causes. In 2013, the river was at its all-time low in the Nizamabad district of Telangana. This had hit the growth of fish, making the life of fishermen miserable. The water-level was so low that people could easily walk into the middle of the river. Shortage in rainfall and closure of the controversial Babli project gates in Maharashtra was thought to have affected the water flow in the river and water availability to the Sriram Sagar Project except during above 20% excess monsoon (i.e. one out of four years) years. A study has found that the delta is at a greater risk as the rate of sediment aggradation (raising the level of the delta through sediment deposition) no longer exceeds relative sea level rise. It further states that the suspended sediment load at the delta has reduced from 150·2 million tons during 1970–1979 to 57·2 million tons by 2000–2006, which translates into a three-fold decline in the past 4 decades. Impacts of this can be seen in destroyed villages like Uppada in Godavari delta, destruction of Mangrove forests and fragmentation of shoreline – possibly a fallout of dam construction. Said to further epitomise the insensitivity towards Godavari, is the Polavaram Project which is touted to be gigantic – both in terms of size and violations. Deemed as being pointless and politically driven, the project raises questions about environmental clearance, displacement of upstream human habitations, loss of forest cover, technicalities in the dam design which are said to play down flood threats and unsafe embankments. High alkalinity water is discharged from the ash dump areas of many coal fired power stations into the river which further increases
