Informal Activites of Tunnal(Dona)’Gem Pit,Tend To Decsend Natural lands of Sabaragamuwa Basin Within Next Twenty Year

Mr.Aravinda Ravibhanu Sumanarathna


Sabaragamuwa is a unique province which consisted special special geological background. Pleistocene fossil deposit & gem trade are most plansible factors for exhibit traits of sabaragamuwa.Rathnapura is the center operation station of Gem trade.Eheliyagoda,Kuruwita,Rathnapura,Pelmadulla are the majority cities which consisted huge gem pits.Business society of Sabaragamu area is getting high currency and economy from Mine Industry,but because of its disorganized activities it’s becoming a threat to the Natural land and Bio diversity. In Sabaragamu basin (0m-6m) high land has become corrosion .Many mines and disorganized Dona mines can be identify


Fig 01:Gem Pit(Dona) In Sabaragamu Basin
Many mine industry courses 100m of diameterand 60m deep major pits have sap and examine the lode . Therefore soil profile made as a vertex and inconstancy land has got created. Though these pits filled with soil back ,during the rainy days it will turn in to marshy land.For a year Sabaragamu area gets  highest precipitation, therefore eventually  land will get destroyed.Because of disorganize activated dona mines main cities of sabaragamu districtthreat to be sink.most of the dona pits are 10m-150m deep and 150 dona’s are there in palmadulla city. 40% of dona mines 40m-100m depth goes through the city. Therefor in different levels of donas goesdown  through the space enclosed soil will sunk down.In 20 years 80% of palmadulla city ,10 % of rathnapura city and 40 % of around the city ,60% of kuruwita city , 10% of Ehaliyagoda city  and 30% of around the city will be in danger  to sink. We would like to discuss the data’s that based  on  land scape in this area have found its sinking  briskly and cusses including natural and activities that has been taken  during 2005 -2015.
