Ireland’s Environment – An Assessment 2016

12

Establishing and implementing an integrated

national land cover, land use and habitat mapping

programme is essential to assist in reporting and

assessing the impact of different land cover and

land use types on the environment.

By integrating

the National Landscape Strategy into land use planning,

sustainable landscape management practices can also be

progressed. For the urban environment the challenge is

to design a future urban environment with public appeal

that incorporates climate-proofing aspects, such as better

outcomes to tackle flooding while minimising the impact

on the wider environment, along with green areas and

wild spaces for wildlife and people, while also meeting the

needs of society. Forward strategic planning for land use

and new infrastructure is needed to ensure that growth

is sustainable and does not add to the environmental

pressures that are already evident, such as the gradual loss

of wetlands over the past two decades or capacity issues in

delivering drinking water and treating urban waste water.

We need to develop new approaches to be able

to tackle systemic and emerging environmental

risks effectively.

Many specific environmental issues are

regulated on a site by site basis, for example the licensing

of an industrial facility or the management of a protected

area. However, across the wider environment there are also

systemic risks, such as diffuse water pollution or decline in

species populations that need different and new approaches

to resolve. The provision of timely environmental data is

crucial to the early identification of these wider risks.

Restore and Protect

Water Quality

Implement Measures that Achieve Ongoing

Improvement in the Environmental Status of

Water Bodies from Source to the Sea

Water protection measures are needed to ensure

that we continue to have healthy rivers, lakes and

estuaries and clean beaches in order to protect

human health, to preserve fish and biodiversity

and to allow our important water resources to be a

driver for sustainable jobs and tourism.

We are still a

long way from meeting the full legal requirements of the

Water Framework Directive, against which water quality

is measured. Preliminary results indicate that there has

been no overall improvement in water quality over the

first river basin cycle (2009‑2015). The target of a 13.6%

improvement in the ecological status of surface waters

(from the 2009 baseline) by 2015 was not achieved. Water

quality improvements are required at approximately 50%

of rivers, lakes and estuaries that are impacted by pollution

or other pressures. The two main suspected causes of

pollution in rivers are agriculture and municipal sources,

accounting for 53% and 34% of cases, respectively.

Physical modifications, such as barriers to fish migration,

are also a key pressure that needs to be tackled. While

overall the length of unpolluted river channel has remained

relatively constant, there has been a substantial loss in the

number of highest quality river sites (i.e. Q value of 5). In

the most recent monitoring period (2013‑2015) only 21

sites were classified as the highest quality river sites (0.7%

of sites) compared with 575 between 1987 and 1990

and 82 between 2001 and 2003. This is an area where

substantial effort is required to protect the few remaining

sites and, where feasible, return impacted ones back to

their earlier extremely high quality.

Urban waste water is still one of the principal

pressures on water quality in Ireland.

There is a

need for continued investment in waste water treatment

facilities. This investment is needed to provide, upgrade

and manage the sewer networks and treatment facilities

necessary to treat sewage and industrial water to the

standard needed to protect human health, and water

quality in our rivers, lakes and coastal areas.

One of the measures being implemented to improve

and protect water quality is the use of a new risk-

based approach to managing water catchments.

This new approach will require much better targeting of

interventions to restore and protect water quality as well

as a greater community involvement in protecting and

managing our water resources.

Ireland’s marine environment has remained relatively

unpolluted; however, the level of environmental

stress both from internal and external sources has

increased.

The sustainability of fish catches continues to

be an issue; 36% are considered to be sustainably fished.

Overfished stocks have declined to 26%, and 38% remain

at an unknown status. Untreated sewage is discharged

at 36 estuarine or coastal locations. Overall, 71% (46 out

of 65) of the urban areas that have inadequate treatment

or do not meet mandatory EU standards, discharged to

estuarine or coastal locations in 2015. Marine litter is

now a global issue and the impacts can be seen on even

the remotest of our beaches. While litter is a key marine

environment and biodiversity challenge, its generation and

prevention are linked to a variety of human activities and

policy areas. Successful implementation of a comprehensive

targeted waste policy is a prerequisite to avoid plastic litter

entering the marine environment.

Other stresses on our coastal environment are

wider and link to the impacts of climate change.

From a climate perspective, rising sea temperature, ocean

deoxygenation, rising sea levels and ocean acidification

(the effects of which are being seen in Irish waters) are

major causes of concern worldwide. The rich coastal marine

grasses and kelp forests are significant carbon sinks (as well

as important biodiversity reservoirs) that need protection and
