Global Change and the Biosphere
Lecture 1 - Concept of Anthorpocene
History and concept of Anthropocene
How various users such are using it: **
Example: Geologists, Earth system scientist, Earth system scientists, geologists, conservation scientists, social
scientists and the wider media.
Different the definition:
Debate on when the date should start
Can there be a 'good Anthropocene'
KEY READINGS:
Malhi (2017) The concept of the Anthropocene
2.‘Was the Anthropocene anticipated?’, iHamilton, C. and Grinevald, J. (2015)
Defining the Anthropocene (Lewis, S. et al (2015 )
Lecture 2;Metabolism of a human-dominated
planet**
Key concepts
Key points
lecture points
What is socio metabolism
what is the metabolism of individuals. and societies in human and insect and societies
(3)
what is an environmental resource use?
and human impacts on
the biosphere through human history
(4) human activity in the
context of global biosphere activity.
how has human impacts on the planet have
increased over time,
Lecture 2: What is the metabolism of a human-dominated planet? Or what is the metabolism of a planet dominated by humans
Readings
1The metabolism of a human-dominated planet, in “Is the planet full?”
Malhi (2014)‘Energetic Limits to Economic Growth’,
2.Our share of the planetary pie’,(Foley, J.A2007
3.the global socioeconomic energetic metabolism as a sustainability problem
Friday fieldtrip to Wytham Woods
key questions of forest ecology in the
context of global change.
Methods
Can plant species composition, diversity and carbon stock be assesed?
whats beein reserached on?
Lecture 3:
Metrics for human impacts on th
e biosphere
what are the different approaches to measuring human impacts on biosphere
What are the criiques and debates
what approaches have been used
A
pproaches and usage
In
clude:
vegetation cover change
Ecological footprints, extinction and animal abundance indcies
Human Appropriation of NPP, and various metrics used to
assess planetary boundaries and Sustainable Development Goals
Trends - past and recent in metrics used
le
cture 4:Tropical forests and global change
Iconic Biome (ie F=Tropical Forest)
Key : Overview : How has the tropical rainforest changed : ito Anthropocene?
What are drivers and spatial patterns?
How do change in forest affect: ?
land use change,
harvesting,
defaunation and
global atmospheric change,
What are the mitigating factors/ How can it be mitigated?
Lecture 5: Animals
What role do they play
Disadvantages:
loss and depletion of animalls:
leads to trophic cascades and of many ecosystems
Examples of where it has happened before
Extinction of Pleistocene megafauna to
c.
Current changes in African savannas
2 Key examples
Passive beneficiaries of he productivity of plants. H
How can animals shape the structure and function of the ecoystem
What key processes are involved
Climate change and biodiversity : Lecture 6: Pam Berry
what drives biodiversity change and loss,
How the impacts of climate change occure
what is the nature of these impacts
what methods are used to
understand these past and future changes.
Modelling challenges: examples
of the challenges of modelling changing biodiversity
What does it all mean for
conservation policy and management in practice
Conservation policy and management in practice
Case studies:: week 7
Key ecological case studies that demonstrate
why tropical gradients are powerful ecological tools
a disturbance gradient in Malaysia
and coffee and cocoa agroforests in Africa,
Different methods to study
