I’ve mentioned Agflation previously and we’re starting to see more concern expressed at the official level. The UK Government’s Chief Scientific Adviser, Professor John Beddington, has weighed into the debate calling food shortages a problem that was as immediate as climate change. The driver of agflation is two fold: increased demand driven by population growth and increasing development and supply shortages caused by deforestation to grow biofuels.

These two drivers are causing major price rises in all food groups. This creates what might be called “real” inflation, a price rise in the cost of real goods as opposed to asset inflation which is more of a monetary phenomenon.

This is a real problem because it can’t be solved by the hammer of monetary policy though the myopists in their central bank ivory towers seem to think so.

I can imagine their conversation: “let’s raise interest rates so people eat less”.

In many countries people are exhorted to have more children especially in developed economies where birth rates among the middle classes have fallen. So how can we stop the population expanding and how are we going to feed all these people and do it in a manner than the ecosystem can cope with.

It’s a tricky question. One could argue that food shortages, famine, disease and natural disasters regulate populations. That may still be the case. But can we rely on that and should we given we are more enlightened, well supposedly.

Population growth was for a long time a favourite topic for policymakers but has only recently come back onto the mainstream agenda. There is no doubt that the growth in biofuels has played a major part in this and that governments who have set targets for biofuel supply may well need to go back and think more carefully about how the unintended consequences of this feel good policy will play out.

Back in January the Indy ran a story on the life and times of battery farmed chickens. As you might expect it didn’t make pleasant reading.

Now following the campaign against battery chickens The Independent reports an complete sell out of free range chickens in the UK.

Figures suggest that in 2007 the sale of battery farmed chickens fell by alomst 10 million birds whilst consumers bought 4.4 million more free range.

This is the consumer voting with their wallets and this is how it should be: a change in individual consciousness.

It’s also interesting the overall sales fell by nearly 5% suggesting that some consumers turned away from chicken altogether.  Again this is an outcome of raised awareness.

It just demonstrates what can be done when the consumer shifts.  

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.
