Paper Description

Edit Paper Description Content
We need to decrease greenhouse gas emissions from Aotearoa and this course will focus on the emissions from land, the processes that control emissions, and conclude by determining possible mitigation strategies. Furthermore, the exchange of water, energy, and trace gases between the atmosphere and terrestrial biosphere underpin the productivity of the land for both agricultural and native ecosystems. These exchanges are also key for controlling greenhouse gas emissions and sustaining global carbon stocks in soil and biomass. This course will examine the processes and controlling factors of these exchanges at increasing scales, major methodologies used for their quantification, and possible approaches for managing undesirable anthropogenic perturbation of these exchanges.

Paper Structure

Edit Paper Structure Content
This paper will comprise a series of lectures supported by provided readings (generally weekly). Students will also make oral presentations of peer-reviewed literature either provided in class or that they have found. Learning will be re-enforced through a laboratory or data analysis experiment that will require individual student reports.
