FOLLOWING incidents of land sinking in different areas of Zanzibar, authorities here have opted to conduct research involving local experts at the State University of Zanzibar (SUZA).
Zanzibar has recorded a considerable number of incidents of subsidence with loss of properties, including houses, vehicles and recently water tanks at Madrasa schools. Subsidence is the sudden sinking or gradual downward settling of the ground’s surface, with little or no horizontal motion.
The definition of subsidence is not restricted by the rate, magnitude or area involved in the downward movement. It may be caused by natural processes or by human activities.
Permanent Secretary (PS) in the Office of Second Vice-President Shaaban Seif Mohamed and SUZA Senior Lecturer Dr Zakia Mohamed Abubakar signed the documents for the research that will also cover the impact of single use plastic (water) bottles and children pampers on the environment.
The signing event was witnessed by the State Minister, Environment, Mr Mohamed Aboud Mohamed who described land sinking as a serious threat to Zanzibar and its immediate solution is inevitable.
“It is high time experts provided answers to these problems. Land sinking in unexpected areas happen during rainy seasons and we also want to get rid of used pampers and plastics litters on our environment,” Mr Mohamed said.
