How much is nature worth?

Nov 13, 2009
Coral reefs, such as this one in the South Pacific, provide ecosystem services worth up to £104 million a year Pavan Sukhdev explains in this year's Annual Science Lecture, The Value of Nature, at the Natural History Museum on 16 November

How much is nature worth? £1 billion? £100 billion? £1 trillion? The loss of our forests and biodiversity in general could cost us between £1.2-2.8 trillion a year, according to Pavan Sukhdev, who is giving this year’s Annual Science Lecture at the Natural History Museum on Monday.

In The Value of Nature lecture, Pavan Sukhdev will talk about this incredible cost of continuing to take nature for granted. He will also explain the costs and benefits of actions taken to reduce these losses.

Pavan is a senior banker at Deutsche Bank and is currently on secondment to the United Nations Environment Programme (UNEP) to lead the agency’s Green Economy Initiative, which includes The Economics of and Biodiversity study (TEEB), the Green Economy Report and the Green Jobs report.

‘Managing people’s desire for things like food, energy, water, and medicinal drugs in a way that reduces the impact on the planet’s diversity is no mean task,’ says Pavan. ‘Indeed this is the greatest challenge that faces society today.’

‘We can look at the world’s economy as a sub-set of the larger of the natural resources and ecosystem services that sustain us’.

Pavan wants natural or nature-based assets, such as coral reefs, to be considered in mainstream economic and policy planning.

Ecosystem services, for example in coral reefs, include things like fish nurseries and coastal defence, and are worth up to £104 million a year Pavan says.

‘An estimated half a billion people depend on them for livelihoods and more than a quarter of all marine fish species are dependent on coral reefs.’

Preserving the world’s protected areas, such as the Greet Barrier Reef, would come at no great cost to society. An annual investment of £25 billion would secure the delivery of ecosystem services worth £3 trillion.

Pavan will also highlight the dangers from . (the variety of life on the planet) is increasingly being put at risk from the impact of greenhouse gases, which are increasing at an alarming rate.

Funding for the protection of endangered habitats is crucial in the fight against climate change.

Forests, for example, are the source of rivers, nutrients for agriculture, opportunities for eco-tourism and food. These so-called ecosystem services are instrumental in protecting vulnerable communities against the impact of climate change already underway.

Pavan Sukhdev gives The Value of Nature, Annual Science Lecture, in the Museum’s Central Hall at 19.30-21.00 on Monday 16 November.

I find it odious that nature is being reduced, like so many other things, to capital. That the question need even be asked to try to make others' aware of the (non-monetary) value of nature is appalling. Nature's value is not derived from its usefulness to an egotistical chattering ape species any more than human relationships are valuable insofar as they can be used for the acquisition of money (i.e. as social capital).
