| The spatial econometrics of elephant population change A note | |
| 2006 Ecological Economics (60): 320-323 | |
While previous research found no other variable than corruption to have a negative impact on the growth rate of the elephant populations of African countries, we show that one further significant impact is exerted by 'neighbourhood effects'. Elephants travel long distances, often crossing borders. Using spatial econometric tools, we find that elephant population changes in one country have a positive impact on population changes in neighbouring countries. Our results have possible policy implications, as they suggest that spatial clustering of funds and of conservation efforts makes sense if the endangered species move across borders. |
