Intrepid. You raise a valid point! Who's responsibility is it to clear the mess up!?
There is a complicating factor which has not been taken into consideration (and I know because this is not the first time EKZNW have seen pictures like this...). The problem with issuing a directive to the land owner is that half the land lies on South African turf and half on Lesotho land. While EKZNW has tried previously to get it cleaned up under the previous law (Conservation of Agricultural Resources Act), and under the current act which replaced CARA (National Environmental Management Act) which clearly indicates that the polluter must pay, Lesotho also need to throw their weight behind the directive. Although the directive come from DEAT and DWAF (pollution of the environment and water), Lesotho also need to issue a directive to the landowner to clean up, before there will be any improvement (unfortunately

).
One angle which may be exploited (and I will have to research this) is to get IUCN and UNEP aware that this type of pollution is happening in a International Heritage site (for its high value of endemic plant and animal species, now threatened by a poisoned water source) and within a potential transfronteir reserve. Furthermore, the majority of the items on the dump should in actual fact be recycled. One wonders what happens to the rest of the rubbish....?
Rest assured though, EKZNW is trying to find a way to clear up the mess on top, even if it were just up to me!
