The effects of climate induced changes in the Arabian Sea on marine and coastal socio-ecological systems in India


Background
The project aims to understand how climate-induced changes in sea surface temperature (SST), salinity, pH, and sources of macronutrients may affect the phytoplankton community structure, and to identify environmental drivers of harmful algal bloom (HAB) species. Such knowledge will enable us to foresee effects in the marine food web affecting e.g. fisheries, and assess the risks HABs and pathogens pose to human health under present and future environmental conditions. Many of the harmful algal species have a vast distribution, and therefore the theoretical models and the validation can be applicable on wide geographical scales.


Objective
To understand how climate-induced changes in SST, salinity, pH, and sources of macronutrients may affect the phytoplankton community structure, and subsequently, marine and coastal ecosystem services on which millions of people along the coast of the Arabian Sea depend.

Methods
My PhD work is mainly focused on:
1. Experimentally testing how the pelagic community (phytoplankton and pathogenic bacteria) will respond to anticipated climatic changes.
2. Construct coupled physical-biological models to characterize the environmental variables that correlate with the initiation and development of harmful microbial bloom species, and determine which species will be most competitive under future climate settings.
3. Validate the models for harmful species expansion by manipulated single species experiment, in which the response on a molecular and physiological level is followed.


Interdisciplinary project
This PhD work is being conducted in close collaboration with Alin Kadfak, PhD student in human ecology at the Department of Global Studies, University of Gothenburg. As part of this interdisciplinary work, we aim to a) identify the most important provisioning ecosystem services that are likely to be negatively affected by an expansion of HABs in the Arabian Sea, b) assess the vulnerability of the users of such ecosystem services along the south-west coast of India and, c) analyze the need for institutional response in India to the socio-economic risks posed by an expansion of HABs in the Arabian Sea.
