A week of food riots has seen the Haitian Prime Minister fired by the Senate. Food is right up there on the National Security watch list along with climate change, peak oil and water. This has been simmering for a while now but is starting to loom as a serious global problem.

It’s not a problem that can be considered in isolation. Speculation in land (financial asset bubble), population growth, the bio-fuel issue and climate change have all contributed to a serious problem with the food chain.

Rising oil prices have just been the icing on this unpalatable cake. Is this likely to be contained to developing or poorer nations? Not so say some. In developed nations just-in-time delivery and stocking systems work on very tight margins. Food banks are under serious strain with a whole new layer of users appearing in recent times.

There’s no simple solution to this situation but governments need to take it very seriously.

It’s good that the water debate is starting to take more shape. In the main we have struggled with the idea that we should pay for it and how to construct proper markets around it. Some places meter water and some don’t but as we know it’s hard to manage a resource if you can’t measure it use.

So it’s refreshing to see a piece in The Press  on the need for a water market to be constructed to provide an efficient allocation of this precious resource. As I’ve discussed many times, a resource with no price will be treated as if it is free. For many people water is free and always has been but now there are competing claims on water. In New Zealand this is primarily from agriculture with huge demands for irrigation from the dairy industry, which converts water into milk on an enormous scale.

Initial objections are alway around the issue that water is a necessity for life and should therefore be free.  Well so is food and shelter and they aren’t. We have lived with the false notion that water will always be plentiful and is a constant renewable resource. Tell that to Australian farmers who have suffered a 5 year drought in many areas. Water availability is subject to climatic variation and to overuse. Just look at the state of NZ rivers and lakes which are well known to have experienced a serious decline in quality over the last 20 years of intensive farming.

It’s fairly simple to make sure people are allocated a fair supply of free water to assuage those who believe they shouldn’t pay for it but anything above a basic amount should be paid for just like our energy.

It’s only through the pain of payment that we really focus our efforts on conservation, efficiency and alternatives.

It’s time we got on with this whilst we still have water to charge for.
