Impacts of climate change on Ecosystem Services

Net harmful impact on ecosystem servicesThe balance of scientific evidence suggests that there will be asignificant net harmful impact on ecosystem services worldwideif global mean surface temperature increases more than 2o Cabove preindustrial levels (medium certainty).

Potential impactsBy the end of the century, climate change and its impacts maybe the dominant direct driver of biodiversity loss and changes inecosystem services globally

- increasing frequency and severity of floodingevents (aggravated by deforestation ofwatersheds, canalisation of rivers)

- degradation and fragmentation of habitats(aggravated by conversion from forest toagriculture and intensification of productionsystems)

• widespread loss of soil fertility

Decline of ecosystem services

Global change

21

Measures foradaptation Scenario IPCC

-Decrease 15-20% total precipitation

- Seasonal distribution:-Increase in winter-Decrease in summer

- Heavy rain

- Heat waves

Measures for adaptationAdaptative land

When ecosystem services are taken into account,the net present value of natural and sustainablymanaged ecosystems is frequently higher than thatof converted and intensively managed systems
