Impacts of climate change on ecosystem services
13 seasonality Wang et al., 2016. In the summer, most
arid and semi-arid regions of China show a negative correlation between temperature and NPP, while in the
spring the correlation may be positive in certain regions. Temperature rise strengthens evapotranspiration and
reduces soil moisture, which can result in drought and can limit growth during the summer. The authors found
that an increase in precipitation is more beneicial to plant growth Hao et al., 2016. Liu et al. 2014 found
that changes in extreme events also afect NPP. A vicious winter storm and extremely low temperatures in early
2008 resulted in a drastic decrease of NPP in forest and grass ecosystems in China’s Hunan province Liu et al.,
2014. Studies related to primary productivity, as with disease and lood regulation and food production, may
indicate that trends and luctuations related to climate change and extreme events have diferent, very locally
speciic, impacts on ecosystem services.
2.4 Example of climate change impact on cultural services
Cultural services comprise a range of largely non- consumptive uses of the environment including the
spiritual, religious, aesthetic, and inspirational wellbeing that people derive from the natural world; the value to
science of an opportunity to study and learn from that world; and the market beneits of recreation and tourism.
Coral reefs ofer an example of potential consequences of climate change for cultural services provided by
ecosystems. Bleaching events in the past three decades have already caused declines in coral across the Great
Barrier Reef Ainsworth et al., 2016. Global warming and ocean acidiication are likely to result in the widespread
loss of coral reefs within a century Hoegh-Guldberg et al., 2007. Coral reefs are an important draw for tourism and
source of recreation in many coastal countries Hoegh- Guldberg et al., 2007. Lane et al. 2015 conclude that
climate change “could result in a signiicant loss of value associated with the diverse ecosystem services these
habitats provide, including tourism, commercial harvest, and existence i.e. non-use values.” However, the
efects are complex. Tourism itself–including boating, snorkelling and diving–can damage reefs UNEP, 2016
and there is evidence that reefs may have a natural ability to tolerate stress. Ainsworth et al. 2016 conclude:
Our analysis reveals that the exposure to sub-lethal pre-stress events varies dramatically among reefs, with
some having an inherent level of ‘protection from’ or ‘preparedness for’ the conditions that induce coral
bleaching, whereas others experience multiple stress
