Harry Vallack is an ecologist specialising in air pollutant emissions inventories, carbon dynamics of plant/soil systems, ambient dust pollution monitoring and issues relating to persistent organic pollutants (POPs).
Harry has over 25 years experience working on various aspects of air pollution at scales ranging from local to global. This has included capacity building within non-OECD countries (including developing of suitable manuals/software) for the preparation of air pollutant emissions inventories, producing air pollution emission scenario projections for developing country regions.
Harry’s current research interests concern short-lived climate pollutants (SLCPs), global change ecology, soil carbon dynamics and capacity building for emissions inventory preparation in developing countries. In the process of this research, he has developed software tools to enable developing countries to compile air pollutant emission inventories. More recently he has helped develop a tool to assist countries prioritise alternative SLCP mitigation strategies, going from emissions estimates through to likely impacts on human health crop production and climate.
Harry’s PhD was on the investigation of carbon dynamics in soil-plant systems using stable carbon isotope (13C) pulse-labelling techniques. This work involved helping to set up and deploy a unique mobile laboratory capable of continuously monitoring the CO2 concentrations and 13C:12C isotopic ratios of soil/plant respiration in the field.
He helped to develop a Frisbee Dust Deposit Gauge and devised “likelihood of nuisance guidelines” for monitoring ambient dustfall. Harry has also worked with the Centre for Low Carbon Futures on a review of the low carbon technologies that key UK energy intensive sectors might use to help meet national emissions targets by 2050.
His POPs work involved writing the working paper for an international workshop on POPs held in York in May, 1998 and editing the final concensus report “Controlling persistent organic pollutants – what next?”
