Transcripts
so today we will start to talking about
some strategies useful for the
achievement of environmental social and
economical sustainability of the new
Tirana okay this instruments that use
vegetation of soils and natural process
to create healthier urban environment
are generally recognized as green
infrastructures green infrastructure
extra things green infrastructure has
recently gained importance as a planning
tool of the regional and local levels
while it provides a range of ecosystem
services greater attention is needed on
integrating the economic environmental
and social benefits produce particularly
in the context of climate change
adoption and mitigation is not a new
policy tool button is meant to further
develop new tools for the common
objectives connectivity biodiversity and
climate change response to fragmentation
and connectivity without forgetting the
related social aspects next hour by
green infrastructure could act as a
delivery mechanism ecosystem services
the absence of an integrated strategy
for the urban build and green areas and
the low connectivity with the Intel and
green areas were the main weakness of
the city the solutions identified by
means of ecosystem services regulation
function address the related measures
anticipate the climate change challenges
and enhance the city's resilience social
economic health and visual aesthetic
benefits could have a particular
emphasis depending of the specific
identified measure next green
infrastructure so is addressing the
spatial structure of natural and semi
natural areas but also over
environmental features which enable
citizen to benefit from its multiple
services the underlying principle of
green infrastructure is
that the same area of land can
frequently offer multiple benefits of
its ecosystem if it's a ecosystem isn't
in a healthy state meaningful slaughter
investment are generally characterized
by a high level of return over time
provide job opportunities and can be a
cost-effective alternative or be
complementary to gray infrastructure and
intensive land-use change the strategy
sells the interest of both people and
NATO next door at the city or county
scale green infrastructure is a part or
a patchwork of natural areas that
provides habitats flood protection
cleaner air and cleaner water at the
neighborhood or side scale it could be
stormwater management system but mimic
nature so happens to water next
different type of green infrastructure
practices are more suitable for specific
situation and landscape reflecting very
treatment levels and provide unique
benefits all of them are part of the
following strategic objectives
connectivity of habitats providing
better linkages between existing and
proposed a green infrastructure
multifunctional e multifunctionality
tailoring various use such as
agriculture access recreation and
biodiversity to the local situation
extended axis battle axes for everyone
and landscaper enhancement the strategy
shall reflect the distinctive pattern of
the Albanian landscape above interim of
its net run in historical and cultural
landscape next the universe of green
infrastructure practices varies between
a regulated entity but some common
categories have a merger we try to
summarize seven main tools next
biodiversity enhancement build bio
Philip buildings increase the canopy
manage stormwater runoff reduce the
water consumption conserve blend the
soil improve public space quality green
infrastructure so next things from the
point of view our biodiversity green
infrastructure is one of the only one
approach to enhancing biodiversity the
built environment properly designed
parks arvin gardens green roofs and
green walls can all contribute to
biodiversity and to take all climate
change green spaces in city do
significantly enhance health and well
bag of urban residents it also improves
social equation on the quality of living
environment from the other hand it means
move toward different landscape topology
different management schedules and
different image of the urban landscape
communication program with the aim to
improve the population involvement
should be carried out and this is what
we could discuss this afternoon we
shouldn't forget the important role on
biodiversity of the agriculture some
changes in agricultural techniques could
have a great impact on biodiversity in
special way so in biodiversity
conservative agricultural practices like
minimum tillage or no tillage
dramatically increases number and
variety of soil organisms avoid the soil
ruptor make with plough finger reduce
the amount of greenhouses gases like
carbon dioxide releasing the atmosphere
and buffer strips along the river say
irrigation Channel give a great
contribution reducing pollution in water
by directing take or inactivation
building covered by vegetative
instructor elements could be designed to
reduce the anthropogenic impact on the
home urban landscape and these can also
serve as aesthetic value for humans next
techniques for the greenery of buildings
are green walls hanging gardens and
green roofs both extensive and intensive
the concept of vegetated roof and walls
is not modern we story also the
Babylonian Hanging Gardens dating back
to once in history it is however a
modern concept to use the gatech
instructor for the express purpose of
conservation and decreasing biodiversity
loss effect combining vegetated walls
and roofs can slightly increase the
floor and found our accessibility with
the plants lamb substrate acting as
pathways this is similar to the use of
green corridors to increase connectivity
on the larger landscape scale target
species in this case our inverter
brightest birth or plants increase the
canopy planting big trees is certainly
the more effective measure to fight
again against the heat island effect
next higher temperatures negatively
affect human health and well-being
particularly in period of heat during
summer months the predicted climate
change will increase intensity and
frequency of heat waves induce amplify
biophysical load several studies have
proved mitigation effects of urban
forestry on air temperatures humidity or
sulfur temperatures but different tree
species have diverging attributes
so the surface temperature on asphalt
areas of the tree shade are up to 15
degrees lower compared with the phone
full Sun expose help of alphas area
areas comparing the growth parameter
only leaf area index and transpiration
show a significant influence on sea
surface temperature and there's a
significant impact on pollutant removal
tool what does it mean this mean they
hire the leaf area index is and the
hiver the transpiration is the high very
cooling effects of the trees so we have
to be able to choose the right trees
next green infrastructure is also a
cost-effective resilient approach to
managing wet weather impacts that
provides many community benefits while
single purpose grace on water
infrastructure conventional pipe
drainage and water treatment system is
designed to move urban stormwater away
from the built environment green
infrastructure as like rain gardens next
reduce and treat stormwater as its
source while delivering environmental
social and economic benefits star some
water runoff is a major cause of water
pollution in urban areas when rain falls
on our rules streets and parking lots in
CT and cities and their suburbs the
water cannot soak into the ground as it
should next some water drains through
gutters stone sewers and other engineer
a collection system and is discharged
into there be water bodies the storm
water runoff carries trash bacteria
heavy metals and other pollutants from
the urban landscape higher flows
resulting from heavy rains also can
cause erosion and flooding in urban
streams
when rain falls in natural undeveloped
areas the water is absorbed and filter
by soil and plants green infrastructure
use vegetation soils and other elements
and practices to restore some of the
natural processes required to manage
water and create a healthier urban
environment next like like this there is
no one best fist approach next okay but
green infrastructure is increasingly
being recognized as an important tool
for enhances enhancing the resilience of
natural system and the built environment
next by identifying working towards
win-win solution Land Trust can help
communities plan management to promote
resilience systems but are able to
respond to current and future climate
change impacts next natural and
construct an infrastructure ranging from
conserved riparian buffers to rain
garden and permeable pavers can help
enhance on water management capabilities
in ways that reduce vulnerabilities to
flooding next pervious pavement allow
water to soak through paved areas such
as parking lot and urban forest canopy
associated with street trees and other
that you discover using green
infrastructure practices can have direct
impacts on as well increase in
permeability reduce water consumption
and I increase the sustainability in
landscape management it means increasing
our ability to use plant accorded with
ecophysiological approach and not only
aesthetical or custom approach okay and
this is a really important preserving
the natural soil means develop
strategies for urban saw
remediation and management and promote
existing soil manufacturing instead of
taking this resource from from
surrounding fields agricultural soil
shall stay where it lays because its aim
is to produce food and in general sense
improve the quality of the public space
means realized that the quality of the
design the care during construction
proper management of the public space
are the basis for acts of sexual then
respected the space to live okay and in
conclusion over the next year's the
population of the Tirana metropolitan
area is expected to increase this
increase in population can be seen as as
an opportunity for improving the quality
of life enjoyed by existing communities
the housing development so will put
pressure on the environment in terms of
habitat loss fragmentation and
disturbance but at the same time will
provide opportunities to enhance the
adjoining green infrastructures which
could link into a strategic network of
green spaces how to do with the green
instrum instrum infrastructure strategy
is what we want to discuss these
afternoon okay thanks
