'World Mangrove Atlas'
highlights the importance of and threats
to mangroves
July 14, 2010, London/Nairobi - The first
global assessment of mangroves in over a
decade reveals that rare and critically
important mangrove
forests continue to be lost at a rate three
to four times higher than land-based global
forests, despite positive restoration efforts
by some countries.
About one fifth of all
mangroves are thought to have been lost
since 1980. Although losses are slowing
at 0.7 per cent a year, the authors warn
that any further destruction due to shrimp
farming and coastal development will cause
significant economic and ecological decline.
Economic assessments
provide some of the most powerful arguments
in favour of mangrove management, protection
or restoration. Studies estimate that mangroves
generate between US$2000-9000 per hectare
annually, considerably more than alternative
uses such as aquaculture, agriculture or
insensitive tourism.
The new atlas also underscores
positive trends. Restoration efforts now
cover some 400,000 hectares, as foresighted
countries make the link between these coastal
forests and economically-important services
from flood defenses and fish nurseries to
carbon storage to combat climate change.
Achim Steiner, UN Under-Secretary
General and Executive Director, UN Environment
Programme (UNEP), said: "The Economics
of Ecosystems and Biodiversity, which is
hosted by UNEP is bringing to the fore the
multi-trillion dollar value of the world's
nature-based assets. This atlas brings our
attention onto mangroves and puts them up
front and central, plotting where they are,
describing where they have been lost, and
underlining the immense costs those loses
have had for people as well as nature".
"Together, the
science and the economics can drive policy
shifts. Some 1,200 protected areas are now
safeguarding around a quarter of remaining
mangroves and many countries are now embarking
on major restorations-a positive signal
upon which to build and to accelerate a
definitive response in 2010, the UN's International
Year of Biodiversity," he added.
"Mangrove forests
are the ultimate illustration of why humans
need nature," says Dr. Mark Spalding,
lead author of the World Mangrove Atlas
and senior marine scientist with The Nature
Conservancy. "In place after place
the book details the extraordinary synergies
between people and forests. The trees provide
hard, rot-resistant timber and make some
of the best charcoal in the world. The waters
all around foster some of the greatest productivity
of fish and shellfish in any coastal waters.
What's more, mangrove forests help prevent
erosion and mitigate natural hazards from
cyclones to tsunamis - these are natural
coastal defenses whose importance will only
grow as sea level rise becomes a reality
around the world."
"Given their value,
there can be no justification for further
mangrove loss. What's urgently needed is
for all those working in fields of forestry,
fisheries and the environment to work together
and communicate their worth, both to the
public and to those with the capacity to
make a difference", said Emmanuel Ze
Meka, Executive Director of the International
Tropical Timber Organization (ITTO) which
provided the bulk of funding for the Atlas.
This book goes a considerable way to communicating
that message."
"The Nature Conservancy
is an organization with its feet firmly
on the ground in 30 countries," said
Mark Terceck, CEO of the Conservancy. "Already
we have teams working to protect and restore
mangroves from Florida to Indonesia, Palau
to Grenada. This book raises the stakes
and engenders urgency, but it also offers
hope. These are robust and resilient ecosystems.
Get things right for them and the payback
will be immense: security for rich biodiversity
and a lifeline to many of the world's most
vulnerable people."
Key Findings from the
Atlas
Loss and restoration
The global area of mangroves
- 150 000 square kilometers - is equivalent
to the area of Suriname, or the state of
Illinois, or half the area of the Philippines.
Mangrove forests straddle land and sea and
are found in 123 countries in tropical and
subtropical regions.
The nations with the
largest mangrove areas include Indonesia
with 21 per cent of global mangroves, Brazil
with 9 per cent, Australia 7 per cent, Mexico
5 per cent and Nigeria with 5 per cent.
The greatest drivers
for mangrove forest loss are direct conversion
to aquaculture, agriculture and urban land
uses. Coastal zones are often densely populated
and pressure for land intense. Where mangroves
remain, they have often been degraded through
overharvesting.
Where vast tracts of
mangroves have been cleared for shrimp aquaculture,
fast profits often left a legacy of long-term
debts and poverty, which are hard to reverse.
According to the FAO
(Food and Agricultural Organization) mangrove
losses have been considerable and are continuing.
Some 35,600 square kilometers were lost
between 1980 and 2005.
While there are no accurate
estimates of the original cover, there is
a general consensus that it would have been
over 200,000 square kilometers and that
considerably more than 50,000 square kilometers
or one-quarter of original mangrove cover
has been lost as a result of human intervention.
Mangroves have now been
actively planted or encouraged to grow through
activities such as site clearance and the
removal of waste. Examples include Australia,
Bangladesh, Benin, Brazil, Cuba, India,
Indonesia, Pakistan, Philippines, Thailand
and Vietnam.
Use and ecological niche
Mangroves contribute
to livelihoods locally and globally by providing
forest resources such as timber, firewood
and thatching materials as well as non-timber
products.
They are also recognized
as an important greenbelt and carbon sink
that protects coastal areas from natural
disasters such as tsunamis, cyclones and
erosion resulting from sea-level rise especially
in small island countries.
There is good evidence
that mangroves even reduced the impact of
the 2004 Indian Ocean tsunami in a number
of locations.
There is also considerable
storage of organic carbon in mangrove soils,
meaning they may have an important role
to play in the process of mitigating climate
change. Preliminary estimates indicate that
the total above-ground biomass for the world's
mangrove forests may be over 3700Tg of carbon,
and that carbon sequestration directly into
mangrove sediments is likely to be in the
range of 14-17Tg of carbon per year.
Mangroves are also among
the most important intertidal habitats for
marine and coastal fisheries. Mangrove related
species have been estimated to support 30
per cent of fish catch and almost 100 per
cent of shrimp catch in South-East Asian
countries, while mangroves and associated
habitats in Queensland, Australia support
75 per cent of commercial fisheries species
Policy and solutions
The destruction of mangroves
is often prompted by local decisions, market
forces, industrial demand, population expansion
or poverty. However, in many countries,
the fate of mangroves is also determined
by high level policy decisions.
In the Philippines,
as an example, state-wide encouragement
of aquaculture dating back to the 1950s
led to massive losses. In Malaysia, by contrast,
state ownership of mangroves prevails. While
there have still been losses, large areas
remain in forest reserves, managed for timber
and charcoal production, with concomitant
benefits for fisheries.
Trends of mangrove gain
or loss can be rapidly and quite dramatically
reversed. Laws addressing the placement
of aquaculture standards or water quality
pollution minimization have greatly altered
the shape of new aquaculture developments
in many countries.
New policies and projects
have led to widespread mangrove plantation
across the Philippines. Policies have led
to the offsetting of mangrove loss by replanting
or restoration with examples in Florida
(US) and Australia.
Many countries, such
as Mexico, Belize, Tanzania and Mozambique,
have also established general legal protection
for mangroves, controlling destructive activities
through strict licensing systems.
The Atlas
The atlas brings together
an unprecedented partnership of organizations
- from forestry and conservation sectors
and from across the United Nations - and
includes a new and comprehensive map and
account of mangrove forests.

Global Trends in Green
Energy 2009: New Power Capacity from Renewable
Sources Tops Fossil Fuels
Global investments in
renewables top non-renewables for 2nd year
Pro-renewable policies
critical to sector's continuing strength,
growth
Clean energy investments
show resilience in recession;
Share of renewable energy
continues to grow
Growth of wind power
in China a key feature of 2009
In 2009, for the second
year in a row, both the US and Europe added
more power capacity from renewable sources
such as wind and solar than from conventional
sources like coal, gas and nuclear, according
to twin reports launched today by the United
Nations Environment Programme and the Renewable
Energy Policy Network for the 21st Century
(REN21).
Renewables accounted
for 60 per cent of newly installed capacity
in Europe and more than 50 per cent in the
USA in 2009. This year or next, experts
predict, the world as a whole will add more
capacity to the electricity supply from
renewable than non-renewable sources.
The reports detail trends
in the global green energy sector, including
which sources attracted the greatest attention
from investors and governments in different
world regions.
Investment in core clean
energy (new renewables, biofuels and energy
efficiency) decreased by 7% in 2009 to the
value of $162 billion. Many sub-sectors
declined significantly in money invested,
including large (utility) scale solar power
and biofuels.
However, there was record
investment in wind power. If spending on
solar water heaters, as well as total installation
costs for rooftop solar PV, were included,
total investment in 2009 actually increased
in 2009, bucking the economic trend.
New private and public
sector investments in core clean energy
leapt 53 per cent in China in 2009. China
added 37 gigawatts (GW) of renewable power
capacity, more than any other country.
Globally, nearly 80
GW of renewable power capacity was added,
including 31 GW of hydro and 48 GW of non-hydro
capacity.
China surpassed the
US in 2009 as the country with the greatest
investment in clean energy. China's wind
farm development was the strongest investment
feature of the year by far, although there
were other areas of strength worldwide in
2009, notably North Sea offshore wind investment
and the financing of power storage and electric
vehicle technology companies.
Wind power and solar
PV additions reached a record high of 38
GW and 7 GW, respectively. Investment totals
in utility-scale solar PV declined relative
to 2008, partly a result of large drops
in the costs of solar PV. However, this
decline was offset by record investment
in small-scale (rooftop) solar PV projects.
The reports also show
that countries with policies encouraging
renewable energy have roughly doubled from
55 in 2005 to more than 100 today - half
of them in the developing world - and have
played a critically important role in the
sector's rapid growth.
The sister reports,
UNEP's Global Trends in Sustainable Energy
Investment 2010 and the REN21's Renewables
2010 Global Status Report, were released
by UN Under-Secretary-General Achim Steiner,
UNEP's Executive Director, and Mohamed El-Ashry,
Chair of REN21. The UNEP report was prepared
by London-based Bloomberg New Energy Finance.
The REN21 report was produced by a team
of authors in collaboration with a global
network of research partners.
The UNEP report focuses
on the global trends in sustainable energy
investment, covering both the renewable
energy and energy efficiency sectors. The
REN21 report offers a broad look at the
status of renewable energy worldwide today,
covering power regeneration, heating and
cooling and transport fuels, and paints
the landscape of policies and targets introduced
around the world to promote renewable energy.
Achim Steiner said:
"The sustainable energy investment
story of 2009 was one of resilience, frustration
and determination. Resilience to the financial
downturn that was hitting all sectors of
the global economy and frustration that,
while the UN climate convention meeting
in Copenhagen was not the big breakdown
that might have occurred, neither was it
the big breakthrough so many had hoped for.
Yet there was determination on the part
of many industry actors and governments,
especially in rapidly developing economies,
to transform the financial and economic
crisis into an opportunity for greener growth."
"There remains,
however, a serious gap between the ambition
and the science in terms of where the world
needs to be in 2020 to avoid dangerous climate
change. But what this five years of research
underlines is that this gap is not unbridgeable.
Indeed, renewable energy is consistently
and persistently bucking the trends and
can play its part in realizing a low carbon,
resource efficient Green Economy if government
policy sends ever harder market signals
to investors," he added.
Mohamed El-Ashry said,
"Favorable policies now in place in
more than 100 countries have played a critical
role in the strength of global renewable
energy investments recently. For the upward
trend of renewable energy growth to continue,
policy efforts now need to be taken to the
next level and encourage a massive scale
up of renewable technologies."
Says Michael Liebreich,
chief executive of Bloomberg New Energy
Finance: "The relatively resilient
performance of the sector during the current
economic downturn shows that clean energy
was not a bubble created by the late stages
of the credit boom, but is instead an investment
theme that will remain important for the
years ahead."
By the numbers:
In 2009 renewable sources
represented:
25 per cent of global
power (electricity) capacity (1,230 gigawatts
(GW) out of 4,800 GW total all sources,
including coal, gas, nuclear)
18 per cent of global
power production
60 per cent of newly
installed power capacity in Europe and more
than 50 per cent in the US; the world as
a whole should reach 50 per cent or more
in newly-installed power capacity from renewables
in 2010 or 2011
Appendix
Major highlights,
UNEP Sustainable Energy
Finance Initiative and REN21 reports
For the first time,
private sector green energy investments
in Asia and Oceania, some $40.8 billion
in 2009, exceeded that in the Americas,
at $32.3 billion.
Private sector investment
in Europe was down 10 percent at $43.7 billion.
Major economies in 2009
began to spend some of the estimated $188
billion in global "green stimulus"
programs announced in September 2008. However,
at the end of 2009, only 9 percent of the
money had been spent, with larger proportions
expected to flow in 2010 and 2011.
After a weak first quarter
attributed to the banking crisis, sustainable
energy investments rebounded in the final
three quarters of last year. The new investment
total of $162 billion in 2009 represented
the second highest annual figure ever (after
2008) - nearly quadruple the sum invested
in 2004.
New investment of $162
billion has added an estimated 50 gigawatts
(GW) of renewable energy generation capacity
worldwide (not including hydro-electric).
This represents a sharp rise from the 40GW
added in 2008. Fifty GW is roughly the output
of 75 coal-fired power plants.
Looking forward
The green power sector
survived the economic downturn better than
many expected, with share prices rising
almost 40% in 2009, reversing roughly one
third of losses experienced in 2008.
Clean energy share prices
under-performed wider stock markets by around
10 percent in the first four months of 2010.
Although oil prices were buoyant, prices
of electricity and natural gas stayed low,
cramping returns for project developers.
Nevertheless, new clean
energy investments in the first quarter
of 2010 (often the most subdued quarter
of the year) were up more than 50 percent
on the same three months of 2009.
Sector Highlights
From 2005 to 2009 inclusive,
the annual average rate of growth in wind
power capacity was 27 percent; solar hot
water 21 percent rate; ethanol production
20 percent and biodiesel production 51 percent.
The use of biomass and geothermal for power
and heat also grew strongly.
Wind
Wind was even more dominant
as a destination for investment in 2009
than 2008.
In 2008, it accounted
for $59 billion or 45 percent of all financial
investment in sustainable energy; in 2009,
it accounted for $67 billion and its share
rose to 56 percent.
Wind power additions
reached a record high of 38 GW, 13.8 GW
of which was installed in China, 10 GW in
the US, and 2.5 GW in Spain.
Wind power existed in
just a handful of countries in the 11000s,
but now exists in over 82 countries.
Solar
Total global investment
in solar PV reached a record $40 billion
in 2009.
Grid-connected solar
power has grown by an average of 60 percent
every year for the past decade, from 0.2
GW at the start of 2000 to 21 GW at the
end of 2009.
The year 2009 was very
different for large-scale (utility-scale)
solar however, suffering a 27 percent fall
in financial investment in the year, to
$24 billion.
The sharp decline links
to several factors, including falling prices,
a sudden over-supply of photo-voltaic products,
new caution on the part of investors towards
equity in young solar companies, a shortage
of bank financing for projects in Europe
and North America and a temporary freeze
on permits for new capacity in Spain, the
most active solar market in 2008.
Solar PV additions nevertheless
reached a record high of 7 GW in 2009. Germany
was the top market, with 3.8 GW added, or
more than half the global market. Other
large markets were Italy, Japan, the United
States, the Czech Republic, and Belgium.
Spain, the world leader in 2008, saw installations
plunge to a low level in 2009 after a policy
cap was exceeded.
In 2009, China produced
40 percent of the world's solar PV supply,
25 percent of the world's wind turbines
(up from 10 percent in 2007), and 77 percent
of the world's solar hot water collectors.
Power produced by solar
PV dropped in price some 50 to 60 percent
by some estimates - from highs of $3.50
per watt in mid-2008, to lows approaching
$2 per watt.
An estimated 70 million
households worldwide now employ solar hot
water heating.
Biofuels
Biofuels, which ranked
third after wind and solar in 2008 with
$18 billion of financial investment, ended
up fourth last year with just $7 billion.
Biomass and waste-to-energy, which was fourth
in 2008 with $9 billion, moved up to third
in 2009 with $11 billion.
Biofuels displaced the
energy equivalent of 8 percent of global
gasoline consumption.
Latin America is seeing
many new biofuels producers in countries
like Argentina, Brazil, Colombia, Ecuador,
and Peru, as well as expansion in many other
renewable technologies.
Investment in new biofuels
plants also declined from 2008 rates, as
corn ethanol production capacity was not
fully utilized in the United States and
several firms went bankrupt. The Brazilian
sugar ethanol industry likewise faced economic
troubles, with no growth despite ongoing
expansion plans. Europe faced similar softening
in biodiesel, with production capacity only
half utilized.
Geothermal
Geothermal suffered
a 29 percent drop in financial investment
in 2009, to $2 billion,
Energy efficiency
Energy-smart technologies
such as power storage and efficiency saw
a 34 percent rise in investment, to $4 billion.
For the first time, energy-smart technologies
attracted more venture capital and private
equity investment than any other clean energy
sector.
* * * * *
Regional highlights
* Europe maintained
its position as the world region with the
largest share of global financial investment
in clean energy - but only just. Its total
came in at $43.7 billion, down from $48.4
billion in 2008.
* Asia and Oceania produced
a sharp increase in financial investment
in 2009, to $40.8 billion from $31.3 billion.
India is fifth worldwide
in total existing wind power capacity and
is rapidly expanding many forms of rural
renewables such as biogas and solar PV.
* North America suffered
a fall in investment, to $20.7 billion from
$33.3 billion
* Middle East and Africa
enjoyed a modest increase to $2.5 billion
in 2009, from $2.1 billion.
* South America saw
investment slip to $11.6 billion from $14.6
billion.
Brazil produces virtually all of the world's
sugar-derived ethanol and has been adding
new biomass and wind power plants.
Public policy: fueling
the rapid growth of renewables
A significant milestone
was reached in early 2010 - more than 100
countries had enacted some type of policy
target and/or promotion policy related to
renewable energy, up from 55 countries in
early 2005.
Many new targets enacted
in the past three years call for shares
of energy or electricity from renewables
in the 15-25 percent range by 2020. Most
countries have adopted more than one promotion
policy, and there is a huge diversity of
policies in place at national, state/provincial,
and local levels.
Manufacturing leadership
is shifting from Europe to Asia, as countries
like China, India, and South Korea continue
to increase their commitments to renewable
energy.
As a group, developing
countries have more than half of global
renewable power capacity.
Developing countries
now make up nearly half of all countries
with policy targets (38 out of 80 countries)
and also make up half of all countries with
some type of renewable energy promotion
policy (41 out of 81 countries).
Markets for renewables
are growing at rapid rates in countries
such as Argentina, Costa Rica, Egypt, Indonesia,
Kenya, Tanzania, Thailand, Tunisia, and
Uruguay, to name a few.
At least 20 countries
in the Middle East, North Africa, and sub-Saharan
Africa have active renewable energy markets.
Outside of Europe and the United States,
other developed countries like Australia,
Canada, and Japan are seeing recent gains
and broader technology diversification.
Globally, renewable
energy industries employ an estimated 3
million people directly, about half of them
in the biofuel industry, with additional
indirect jobs well beyond this figure.
Both within and outside
of Europe, public-sector banks like the
European Investment Bank and Germany's KfW
have been taking an expanding role, including
in many emerging markets like Brazil.
Another force propelling
renewables in developing countries is the
huge increase in development assistance
flows. Such flows jumped to over $5 billion
in 2009, compared with some $2 billion in
2008. The largest providers are the World
Bank Group, Germany's KfW, the Inter-American
Development Bank, and the Asian Development
Bank. Dozens of other development agencies
provide growing amounts of loans, grants,
and technical assistance.
Public support for sustainable
energy remained high in most countries but
action to curb emissions dropped as a priority
for some voters due to the recession, controversies
over climate science last winter and cold
winter weather that hit the most populated
parts of the Northern Hemisphere.
By spring 2010, the
sector was facing fresh challenges as a
second phase of the economic downturn developed,
with governments running into pressure to
cut their deficits and volatility returning
to markets.
