Do countries that invest more on conservation actually achieve better results?

丁香园AV 's Arne Mooers is a member of an international research team that released a study today in Nature confirming that countries that spend more money on conservation had less of their biodiversity subsequently threatened with extinction. They also found countries that spent less saw more of their biodiversity inch towards oblivion. 

The researchers from Canada, the U.S and the United Kingdom took seven years to compile and analyze a dataset that tracked $3 billion in annual conservation expenditures by 192 countries.

With the help of the dataset, they developed a model that can predict where expenditures can best protect biodiversity. Decision-makers can now forecast what conservation spending will achieve under various country-specific growth and development scenarios.

鈥淥ne of our most interesting findings is that the same amount of money goes further in poorer countries than in richer countries,鈥� says Mooers.

鈥淭his may be because many species have already been lost in the richer countries, making conservation spending actually less effective.鈥�

The study also found that fast economic growth negatively impacts conservation spending.

鈥淭his suggests economic development overrides conservation in rapidly-developing countries,鈥� says Mooers. 鈥�

He says governments should double-down on conservation in those countries, like Indonesia, in order to achieve a win-win outcome.
