GLOBAL ASSESSMENTS
Millennium Ecosystem Assessment (2005)
•
•
60% of the ecosystem services are being
degraded or used unsustainably and their
degradation could grow significantly worse
before 2050 due to rapidly growing
demands for food, freshwater, timber, fiber
and fuel.
Environmental degradation and loss of
ecosystem services is a barrier to the
attainment of internationally agreed
development goals.
Global Deserts Outlook (2006)
•
The impact of changes in precipitation and
temperature patterns due to global climate
change is likely to be felt hardest in desert
margins and in desert montane areas.
Drought episodes are projected to become
even more intense and frequent in the future.
GLOBAL ASSESSMENTS
Global Biodiversity Outlook 2 (2006)
•
Biodiversity is being lost at all levels
•
Only two-fifths of the world’s ecological
regions reaching the 10 % benchmark set
out in the provisional framework for the 2010
biodiversity target.
•
Habitats are being fragmented, affecting
their ability to maintain biological diversity
and deliver ecosystem services.
•
The average abundance of species is
declining, showing a 40 % loss between
1970 and 2000. Species in rivers, lakes
and marshlands have declined by 50 %.
•
The threats causing biodiversity loss are
generally increasing, and these include an
increase in invasive alien species, overexploitation and nitrogen-loading, which
leads to “dead zones” in marine systems.
CENTRAL MESSAGE FROM THESE GLOBAL
ASSESSMENTS
Environmental degradation and loss of ecosystem services is a barrier to the
attainment of development goals
There are no quick fixes
Background: State of the Environment Reporting
•
First national state of environment report
was released in 1999
•
Since then various national, provincial,
municipal and sectoral state of environment
reports were published.
•
The purpose of these reports is to:
– Provide information on the state of the
environment in accordance with NEMA
Section 31 (Access to information)
– Increase public awareness about
environmental and sustainability issues
•
Target audience:
–
–
–
–
Policy and decision-makers
Learners and youth
Public – civil society and private sector
Media
2006 SOUTH AFRICA ENVIRONMENT OUTLOOK

MAIN MESSAGES: POSITIVES
•
Significant progress in the area of environmental
management.
– Laws and strategies developed that focus
on key areas,
• biodiversity,
• air quality
• protected areas
• urban and rural development
• waste, and disaster management.
–
Efforts to implement and enforce the policy
framework have intensified.
–
Improving environmental conditions include
some fish stocks, which have recovered
due to good management measures, and a
slowing of habitat loss in some areas of the
country.
–
Programmes to rehabilitate ecosystems
while creating jobs have received greatly
increased budgets.
MAIN MESSAGES: POSITIVES
• Since hosting the World Summit on Sustainable
Development in Johannesburg in 2002, South
Africa has continued to play a prominent role in
international environmental governance.
• Increased attention to environmental fiscal
reform, cleaner production, energy efficiency,
and renewable energy.
MAIN MESSAGE: CHALLENGES
– The ecological footprint per
person in South Africa is
higher than the global average
(2.8 hectares per person in
South Africa compared to a
global average of 2.3 hectares
per person),
– and increased by 2% between
1991 and 2001. In other
middle- and low-income
countries, the average
ecological footprint declined in
this period.

Total Energy Footprint
Ecological footprint is a measure of human demand on
ecosystems. It represents the amount of biologically
productive land and sea area needed to produce the
resources a population consumes and absorb the
corresponding waste
MAIN MESSAGE: CHALLENGES
• In general, the condition of the South African
environment is deteriorating.
– Increasing pollution and declining air quality are harming
people’s health in some areas.
– Natural resources are being exploited in an unsustainable way,
threatening the functioning of ecosystems.
– Water quality and the health of aquatic ecosystems are
declining.
– Land degradation remains a serious problem.
– Up to 20 species of commercial and recreational marine fish are
considered over-exploited and some fish stocks have collapsed.
STATE AND TRENDS
Blue Issues
Fresh water
Water availability
Water quality
WATER AVAILABILITY
•
We have less water available, of
poorer quality than before.
•
Almost all exploitable sources are
tapped, resulting in decreased
freshwater flows in rivers.
•
There are deficits in available
water in more than half of the
water management areas.
•
There is a noteworthy amount of
water transfer between water
management areas, which can
have adverse ecological impacts.
WATER QUALITY
• Water quality is variable, with
some deterioration since the
last state of the environment
report.
• Inadequate controls over
pollution and land-use
practices have led to a
significant proportion of our
exploitable water resources
being degraded.
• The health of river ecosystems
is declining on the whole.
WATER AND CLIMATE CHANGE
•
There should be sufficient water to
meet all needs in the near future,
provided there is careful management.
•
Allowances for the ecological
component of the reserve are not
currently being met in many cases.
•
The effects of climate change on water
availability have not been factored into
these calculations. Thus this
prognosis may change.
•
By 2025 at the latest, there will be a
deficit in available water.
•
Climate change could result in a 10%
reduction in runoff by 2015

CLIMATE CHANGE - GLOBAL TRENDS
•
Absolute temperature has increased by about 0.6 °C over the last century.
•
During much of the last decade, annual ambient temperatures were higher than
the long-term average.
•
Global temperatures will likely rise a further 1.1 to 6.4 °C during the 21st
century

TEMPERATURE TRENDS SOUTH AFRICA
•
South Africa’s annual mean temperature has generally risen between 1960 and 2003,
although this trend is not consistent throughout the country with some areas showing
little upward trend and some a small downward trend. Over this period,
temperature increased on average 0.13 °C per decade (or 1.3 °C per century).
•
Days with warmer temperatures have generally increased while days with cooler
temperatures have decreased.

Sea Surface Temperatures and Sea Level Rise
South Africa
•
•
South Africa’s annual mean sea surface temperature also shows a general upward trend over the
last century. Over this period, mean annual sea surface temperatures increased by about 1 °C.
Successive IPCC reports have reduced their estimates of projected sea-level rise (currently
estimated at between 0.18 and 0.59 meters by 2099.
As the sea level rises, there will be increased coastal erosion, higher levels of saltwater going into
estuaries and groundwater, and greater vulnerability to extreme storms.

gas emissions
CLIMATE CHANGE IMPACTS
•
Climate change will have profound effects on human
well-being, the economy, and the environment.
– Reduced freshwater flow in rivers
–
Climate-induced changes to our coast will
adversely affect the fishing industry, especially
subsistence fishers.
–
Impacts of existing environmental problems
such as land desertification could combine with
the effects of climate change to increase their
harmful nature.
•
Responses to global warming are not expected to
reverse trends in the near future.
•
The predicted effects of climate change, such as
increased floods and droughts, reduced water
availability, and greater land degradation will impact
very heavily on the large numbers of vulnerable
South African people.
AIR QUALITY
Results from National Economic Development and
Labour Council shows:
–
Elevated PM10 concentrations occur
across the country, with levels exceeding
South African National Standard
–
Significantly high concentrations of fine
particulates occur within fuel-burning
residential areas. Health safety limits are
frequently exceeded.
–
Increasing NO2 concentrations along busy
traffic routes within metropolitan areas
have been detected over the past decade.
–
The SANS annual limit for benzene (C6H6)
is exceeded at all traffic-related monitoring
sites.
–
Elevated PM10, SO2, NO2, and C6H6
concentrations, in excess of air quality
limits, have been recorded at industryrelated monitoring stations.
CONSUMPTION OF OZONE DEPLETING SUBSTANCES
• Consumption of several
ozone-depleting substances
decreased from 1998 to 2001
Consumption of HCFCs
300
– but has been increasing since
2001, with an increase in HCFC124 consumption since 2002.
– However, a small amount of legal
CFCs are imported and exported
to fill asthma inhalers as well as
air conditioners and refrigerators
manufactured before 1996.

REFUSE REMOVAL
• Number of households not receiving adequate refuse removal in
SACN cities increased by 90 073 between 2001 and 2004
• This is an increase of 13,3 % an a reversal from the declining trend
between 1996 and 2001
• This has serious implication for environmental sustainability

STATUS AND TRENDS
Biodiversity and Ecosystems
Aquatic ecosystems
Rivers
Marine and coastal resources
Terrestrial biodiversity
POSITIVE TRENDS
•
In parts of the country habitat loss is
slowing due to:
–
–
–
stock removal programmes,
conversion from stock to game farming,
removal of incentives for vegetation
clearing
•
Working for Water Programme’s budget
increased significantly – important
programme with regard to poverty
alleviation
•
Several contractual parks were
established. SA played leading role in the
establishment of transfrontier
conservation areas
•
Spatial Biodiversity Assessment
completed
AQUATIC ECOSYSTEMS
•
Aquatic ecosystems are in the worst
shape, and are experiencing a rapid
loss of functioning.
– When the river ecosystem status
outputs are compared with those
of terrestrial ecosystems, it
becomes clear that the state of
river biodiversity in the country
needs urgent attention.
•
Wetlands:
– Estimated 50% of South Africa’s
wetlands have been destroyed or
converted.
– Only 10% fully protected
– There is no available information
on about 66% of them, which is a
serious impediment to our ability
to protect and manage this
valuable resource adequately.
RIVERS
•
The health of river ecosystems is
declining on the whole, with
effluent pollution continuing to
grow.
–
–
–
•
Generally in good to fair condition in
the upper reaches and tributaries
In fair to poor condition in the lower
reaches.
Most rivers in highly urbanized areas
are in poor condition
Rivers: 48% are moderately
modified, 26% are largely to
critically modified, while 26% are
intact.
MARINE AND COASTAL RESOURCES

ESTUARIES
•
Some estuaries are in poor state of health and is declining.
– The condition of 28% of them is considered to be excellent; that of another 31%
is good; 25% is classified as fair and 15% as poor. The overall level of protection
of South African estuaries is low.
– Estuaries around intensively developed areas (Cape southwest coast, Port
Elizabeth, and southern KwaZulu-Natal) are in the poorest condition.
WASTE WATER INTO THE MARINE ENVIRONMENT
Daily wastewater discharge is 62% greater than five years ago, even though the number of
discharge points has only increased by four, which indicates a significant increase in
wastewater volume per discharge point – most released in surf zone.

MARINE AND COASTAL RESOURCES - CHALLENGES
•
MPA’s are not representative of marine and
coastal biodiversity. Many of the marine
zones on the west coast lack protection and
are among the most severely threatened
ecosystems in the country.
•
Extractive use is the main threat to marine
biodiversity. A recent evaluation indicated
that up to 20 species of commercial and
recreational marine fish are considered
over-exploited or collapsed.
•
By catch remains serious problem
•
Wastewater discharge into marine
environment has increased substantially
•
Reduced freshwater flow have adverse
impact on estuaries
Climate change impacts:Sea-surface temperatures
off southern Africa appear to have increased by
about 0.25°C per decade over the last four decades can severely affect marine ecosystems and
productivity
The potential impacts of sea level rise on coastal
environments include increased coastal erosion,
inundation, increased salt water intrusion, raised
groundwater tables, and increased vulnerability to
extreme storm events.
TERRESTRIAL BIODIVERSITY
•
Generally in a better state than that
of river and marine ecosystems.
•
Areas of high biodiversity
unfortunately coincide with areas
facing the greatest pressures –
namely the southwestern Cape, the
central grasslands, and the eastern
coastal regions.
•
Widespread land degradation is
causing loss of functioning of
ecosystems and reducing the
productivity of land, which has
serious consequences for the
livelihoods of the rural poor.
•
Recent assessments indicate that
almost 10% of South Africa’s birds
and frogs, and 20% of our
mammals, are threatened.
PROTECTED AREAS
About 6% of SA is formally protected and the protected area network does not
sufficiently represent all habitat types –
110 of 447 vegetation types are not protected at all
Only 10% of wetlands are protected
9% of coastline fully protected

ALIEN INVASIVE SPECIES
•
The rate of spread of invasive plants is
increasing more rapidly than can be managed
through existing programmes for their
removal.
•
Significant adverse consequences for
biodiversity and reduces stream flow in rivers,
which in turn has a negative influence on
aquatic and estuarine biodiversity.
•
Invasive alien plants have invaded over 10
million ha.
•
One million hectares of land have been
cleared of invasive alien plants during the past
eight years
•
Controlling them is currently costing South
Africa an estimated R600 million a year. A
similar investment will need to continue over
the next 20 years to be successful.
TERRESTRIAL BIODIVERSITY: CHALLENGES
• Will be difficult to attain the goal of reducing the rates of
biodiversity loss by 2010
• Aquatic ecosystems in poor condition and some west coast
ecosystems are regarded as critically endangered
• Wetlands continue to be destroyed – need full assessment
of wetlands in South Africa
• Over-harvesting of indigenous plants for subsistence and
commercial use.
• There remain some critical indicators for which we have no
adequate data and without which our assessment of the current
situation is incomplete
– land cover
– finer scale information on habitat degradation/sensitive areas.
LEVERAGE POINTS FOR IMPROVING THE
STATE OF THE ENVIRONMENT
•
Information for decision-making
•
Building capacity
•
Strengthening implementation and enforcement
•
Mainstreaming the environment
INFORMATION FOR DECISION-MAKING
•
•
•
•
•
•
Improve access to environmental information
Use appropriate technologies such as remote sensing and the Internet to provide
access to information
Integrate the collection, management and sharing of information and reports on
environmental and other related matters across all government departments and
research institutions
Set in place mechanisms to fill data gaps for environmental priority areas:
–
–
–
–
–
–
–
areas of air quality, carbon emissions,
Waste,
some aspects of water quality,
groundwater use and recharge,
spatial aspects of land and habitat degradation,
cultural heritage,
human vulnerability, and
–
certain aspects of biodiversity.
Continue the ongoing development of appropriate environmental indicators and indices.
Ensure the appropriate translation of environmental science and research into practical
policy and into public information that is useable and understandable.
BUILDING CAPACITY
•
Increase investment into sustainability-focused research and
development
•
Target and develop civil society education and awareness around the
value of natural capital for human well-being
•
Assist current land-use planning and administration to deal effectively
with priority environmental issues.
•
Focus capacity-building efforts for environmental management at the
local level on the priority environmental issues including air quality,
biodiversity, and climate change
•
Establish partnerships to improve access to information.
– Special attention should be given the organizations
representing women, youth and vulnerable groups.
•
Extend the application of information and communication technology
STRENGTHENING IMPLEMENTATION AND
ENFORCEMENT
•
Roll out national environmental capacity-building programme for local
government.
•
Facilitate implementation and enforcement in key environmental priority
areas.
•
Improve the capacity within regulatory authorities to effectively
manage, implement and review the various Integrated Environmental
Management procedures and tools, notably the new EIA Regulations.
•
Mobilize sufficient resources and ensure appropriate, adequate, and
continuous training for Environmental Management Inspectors
throughout the country.
•
Train the judiciary in the principles of environmental management and
sustainable development and build legal capacity within the relevant
national and provincial departments.
MAINSTREAMING THE ENVIRONMENT
• Bringing environmental sustainability principles into the
mainstream of all aspects of governance, planning, decisionmaking and operation.
• Incorporate the depletion and degradation of natural resources
into national economic systems.
• Increase focus on the value of natural capital to human wellbeing.
• Create a shift from a model of weak sustainability to one of
strong sustainability which recognizes the heavy dependency of
our economy and our society on the services produced by the
natural environment.
