Water harvesting is the collection of runoff for productive purposes. Instead of runoff being left to cause erosion, it is harvested and utilized. In the semi-arid drought-prone areas where it is already practiced, water harvesting is a directly productive form of soil and water conservation.

Asked this before but can't find the link to it. So how many teachers employ caning as a punishment method? I have read both pros and cons to it. Curious about your take on it.
Still many teaches do. But I am against it. It instills fears in mind of students rather than disciplining them.
