 Natural capital is very important in that it helps us achieve the objectives of poverty reduction, it helps us to achieve our goals of economic growth in a sustainable fashion and more importantly it ensures that the benefits out of the natural capital accrue to broader public than few influential individuals. It also helps our future generations to be able to generate their own livelihood from that natural capital if it is well preserved. Yes, in the context of Durban City there was an investment in preserving the coast where we invested in the upper catchment management by helping to deal with waste management by helping to prevent any industrial effluent into the river and ecosystem so it has helped in ensuring that our coast has clean water and is attractive to tourists. So far the investment in natural capital in the example that I've given of Durban has been in the form of grants that have come from government. I believe that we can improve that in the future by ensuring that for every big development that is going to rely on the natural capital there is some money that is contributed by the developers towards the preservation or upgrade of natural capital. When you look at the coast in particular because it benefits tourism sector we can be able to charge some tourism levy per tourist the part of which should be used to manage that particular natural capital for the benefit of the tourism sector.
