SESD Flashcards
how do we track the progression of the Anthropocene
CITE
Atmospheric CO2 concentration - the single indicator
(steffen et al, 2007)
what is
* the pre industrial,
* 1950
* current level
of atmospheric CO2
and cite
270-275 ppm
310 ppm
380 ppm
(Steffen et al, 2007)
what are the 3 phases of the Anthropocene
and cite
- Industrial era (1800-1945)
- Great Acceleration (1945 - ca. 2015)
- Stewards of the Earth System (2015-?)
(Steffen et al, 2007)
3 broad philosophical approaches to deal with changing environment.
and cite
- business as usual
- mitigation
- geo engineering
(Steffen et al, 2007)
What does Stewards of the Earth system mean?
and cite
third stage of the Anthropocene where human activities are recognised as affecting the structure and functioning of the Earth system as a whole
(Steffen et al, 2007)
what has aided the growing awareness of human influence on the Earth system
and cite!
- rapid advances in resource and understanding - most innovative is interdisciplinary work on human environment systems
- enormous power of the internet as a global, self organising info system
- spread of more free and open societies supporting independent media
- growth of democratic systems narrowing scope of arbitrary state power and strengthening role of civil society
(Steffen et al, 2007)
what assumptions do we have in the business as usual approach of the Anthropocene
and cite
- global change will not be severe or rapid enough to cause major disruptions to the global economic system or other important aspects like human health
- the existing market system can deal autonomously with any adaptations required.
- resources required to mitigate global change proactibely would be better spent on more pressing human needs
(Steffen et al, 2007)
example given in of existing economic system dealing with environmental issues
and cite
- as socieites have become wealthier, they have dealt effectively with some local and regional pollution problems.
- clean up of major european rivers
- amelioration of acid rain problem in W. Europe and eastern N. America
(Steffen et al, 2007)
Considerable risk of business as usual approach
and cite
- there is a mismatch in time scales between human decision making/economy and the Earth system
- when humans realise a business as usual approach may not work - the world is already committed to further decades, even centuries, of environmental change
(Steffen et al, 2007)
example of time mis match between Earth system and human decisions/economy
stability of cryosphere
* warming is projected to be twice as large in polar regions enhancing ice sheet instability and glacial melting.
* irreverisdble threshold may in decades be crossed, leading to loss of Grenland ice sheet over centuries or a millenium - thus 5m sea level rise
(Steffen et al, 2007)
outline the mitigation approach
and cite
- attempts to take human pressure off the Earth system by vastly improved technology and management, wise use of resources, control of human and domestic animal population, careful use and restoration of natural environment
- ultimate goal is to reduce human modification of global environment to avoid dangerous levels and rates of change - allow Earth System to function in a pre Anthropocene way
(Steffen et al, 2007)
how is technology used in the mitigation approach
and cite
- rapid advances in transport, energy, agriculture and other sectors have led to a trend of dematerialisation in several advanced econs
- amount and value of econ activity grow while physical material flowing through econ does not
(Steffen et al, 2007)
further technological opportunities - Mitigation approach
and cite
- worldwide energy use is only 0.05% of solar radiation reaching continents
- human appropiation of NPP is around 10%
- new energy generation - solar, thermal, photovoltaic, nuclear, wind, biofules etc
(Steffen et al, 2007)
why might improved tech not be enough in the mitigation approach
and cite
- changes in societal values and individual behaviour will likely be necessary
- Great Acceleration has considerable momentum and intensifying.
(Steffen et al, 2007)
Outline the geo engineering approach
and cite
- severity of climate change may force societies to drastic action
- purposeful manipulation by humans of global scale Earth system processes with the intention of counteracting anthropogenically driven environmental change
(Steffen et al, 2007)
2 Example of geo engineering given in (Steffen et al, 2007)
- artificially enhance Earth;s albedo by releasing sunlight reflective material, like sulphate particles, into stratosphere which would then settle in troposphere
- particles would be produced through oxidation like after volcanic eruptions
- ** geosequestration ** of CO2 into underground reservoirs - would also reduce ocean acidification
What reduction in emissions is needed to stabilise concentration of atmospheric CO2
and cite
60%
(Steffen et al, 2007)
what does IGBP stand for
International Geosphere-Biosphere Programme
What does IPBES stand for
Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services
how many SDGs are there
17
what report says what about the decline ecosystem services?
and cite
they have continued to decline globally since 1970
IPBES
(United Nations, 2021) report says what about the SDGs
World has deviated off its track to achieve the goals by 2030 due to range of health, economic and social imacts of Covid 19.
How has geography changed during the Anthropocene ?
and cite
Moved from merely a collection and description of knowledge to understanding of coupled patterns and processes and the simulation and prediction of complex human and earth systems that now provides support for decision making.
(Fu et al, 2021)
LSS framework and cite
Landscape Sustainability Science
- guides on how to improve capacity of a landscape and provide landscape specific ecosystem services crucial for SD.
(Wu, 2013)
3 Frameworks discussed to promote Geography for sustainability at where
cite all
- Landscape Sustainability science - (Wu, 2013)
- Metacoupling (Liu, 2017)
- Pattern-Process-Service-Sustainability (Fu and Wei, 2018)
at the International Geography and Sustainability Workshop 2021
Outline the PPSS framework
and cite!
- Relationship between land use and ecological processes help us understand mechanisms of ecosystem services and resoure utilisation
- key is balancing nature supplies with human demand at the individual/community level - securing human well being and promoting SDGs
- we develop models and dynamic prediction to achieve this
(Fu and Wei, 2018)
4 Key elements for promoting sustainability
and cite!
- agricultural development
- disasters and risk monitoring and regulation
- climate change mitigation
- achieving the SDGs
(Fu et al, 2021)
4 core higher level facts about land systems
and cite!
- 1 - meanings and values of land are socially constructed and contested
- 2 - Land systems exhibit complex behaviours with abrupt, hard to predict changes
- 6 - humanity lives on a used planet where all land provides benefits to societies
- 10 - land users have multiple, somtimes conflicting, ideas of what social and environmental justice entails.
(Mayfroidt et al, 2022)
Fact 1 - Land is a source and focus of Multiple meaning and values
outline the meaning of this
and cite!!
- while being a biophysical reality, land is also humanity’s home
- notions of land being valued and useful are social constructions from diverse, changing, beliefs
- notions of degredation and restoration are up to interpretation:
- shifting cultivation and use of fire in vegetation management - traditional land use practices viewed by some as backward.
- estimates of land degradation range from 10-60 Mkm2
(Mayfroidt et al, 2022)
3 cosmovisions of the global
and cite!
- African - ubuntu
- Buddhist - Gross National Happiness
- Native American - Buen Vivir
(Van Norren, 2020)
what are the problems with SDGs
and cite
- embody linear growth/results thinking which requires unlimited resource exploitation - dont think about replacing growth with well being
- represent individualism and exclude private sector responsibility
- dont represent collective agency - they imply development as a service
(Van Norren, 2020)
what could be changed in the name SDG
and cite!
- abolish development and replace with inter-relationship
- replace goals with process thinking
- replace sustainability with thinking in cyclical nature and earth governance
(van norren 2020)
3 ways of viewing nature
- intrinsic essence of something - ie natural
- inherent force - ie Mother Nature
- external world - something other
brief outline how nature was viewed through time - Card not complete skip
- enlightenment - **nature is separate, **can be observed through scientific methods
- 1960s-80s -** nature is a limit to growth.** it is a fixed stock, population cannot grow too much
- nature influence
how have policy goals changed broadly
moved from efficiency to justice
what are the 4 types of ecosystem services
and cite
supporting
regulating
cultural
provisioning
(Millenium Ecosystem Assessment, 2005)
why are ecosystem services called instrumental
and cite
we use them as humans, even if not materially
(Millenium Ecosystem Assessment, 2005)
overall, what do the frameworks like coupling actually mean
expanding on ecosystem services but coupled with time, space, scales
what is telecoupling and cite
how actions in some place will affect other side of the world
like what happens in the amazon will affect the Uk
(IPBES, 2016)
what does NCP stand for
and cite
natures contribution to people
(IPBES, 2018)
what does it mean to positivist
there is an objective truth that can be discovered
are ecosystem services positivist ?
yes
what are the 5 types of capital
and cite!
natural, human, social, manufactured and financial
(porritt, 2005)
what does the capital assets framework put forward
and cite
natural capital is a stock resource that we need for wealth and thus well being
(Porritt, 2005)
what is a problem with the capital assets framework
it assumes substitution, you can replace natural capital with produced capital
what is earths overshoot day mean
the date when humanity demand for ecological resources in a given year exceeds what the earth can regenerate in a that year
why were countries like the UK largely able to handle SO2, NO2, toxic waste
we knew the amount of safe amount within our own jurisdictions
outline the planetary boundaries aim
and cite
aims to define a safe operating space for human society to develop and thrive, based on our unederstanding of the functioning and resilience of the earth system
(rockstrom et al, 2009)
