Sedimentation and turbidity in the Zigi River in Tanzania is increasing, but measures such as agroforestry, bench terraces, grass stripping and other soil and water conservation practices can help improve water quality.

“Upstream communities have showed commitment and engagement in sustainable land use practices and stopping subsistence agriculture, which threatens downstream water users,” says the article.
