Answer:
a vegetated buffer-strip near the water body that sheds the water and protect it from the impact of agricultural land use.
Step-by-step explanation:
The intensive agricultural practices of our time continuously lead to unsustainable loss of soil, which end up in our drainage ditches together with nutrients and chemical run-off that gets our water bodies polluted. The use of riparian (stream-bank) buffer has proved to be one of the effective management techniques that can help mitigate the issue.
The techniques involves the use of a vegetated buffer-strip near the water body that sheds the water and protect it from the impact of agricultural land use. With this, a cleaner and healthier water in streams can be found.
