Drivers of change in the North American electric grid
In the first part of this thesis, background material will be covered to motivate the research ideas being pursued in relation to electromechanical disturbance propagation, which is caused by an imbalance in power supply and demand at any location of an electric grid. The delay associated with this …

An analysis of organisational adaptation to climate change: the case of the Bardiya National Park
… with understanding how the management authority of the Bardiya National Park (the BNPMA) is able to adapt to the pressures of increasing climate variability and change. To that end, this study employs a mixed-methods case study approach to elucidate the key drivers of change facing the BNPMA, the …

Forests under threat? Changes in land use and forest cover in rural western Uganda
Deforestation and land use change are widespread in western Uganda. However, the spatial patterns and time-series of change and the reasons why it is occurring remain to be fully investigated. In this work a combination of satellite imagery and social surveys is used to quantify forest gains and …

Ecological Responses to Climate Change: Using the Common Ragworm (Hediste diversicolor) as an Indicator for Benthic Ecosystems
Climate change is projected to have a negative impact on biodiversity over the next century. Similar drivers of change have been observed in the geological past and were also associated with loss of species, particularly in the marine environment. This research uses the common ragworm Hediste …
