Profile

Biography

Dr Harry Vallack 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, preparing the working paper for an international workshop on persistent organic pollutants (POPs) and developing methodologies for monitoring nuisance dust. 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.

Research

Overview

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.  

Projects

Climate and Clean Air Coalition (CCAC) project: Supporting National Planning for Action to Reduce Short-Lived Climate Pollutants (SNAP Initiative). Currently leading the development of the LEAP-IBC software tool to help countries prioritise action on SLCPs by producing emission scenarios and quantifying the health, crop yield and global temperature benefits from selected SLCP mitigation options.

Defra BD5104: “Restoration of blanket bog vegetation for biodiversity, carbon sequestration and water regulation” http://peatland-es-uk.york.ac.uk/ (Funder Defra UK; £850k; Nov 2011 – March 2017). This catchment-scale project is acquiring experimental data from three UK sites to underpin the development and refinement of possible management techniques to address the dominance of heather (Calluna vulgaris) and facilitate the support of ‘active’ blanket bog vegetation (with peat-forming species, particularly Sphagnum spp.).

Earth Observation & Modelling Agri-Tech to Understand Chinese Agricultural & Forest Fires in Relation to Management Practice & Climate Drivers. (STFC; £58k; July 2015 – March 2016). This project focuses on the two principal types of landscape scale burning that occur widely throughout parts of China (i) agricultural fires that burn in crop growing regions and which occur annually over very large areas, lit purposely to remove material from the land prior to harvest, and (ii) forest fires that occur in any one location very much less frequently than agricultural fires, but which can have significant impact on both forest ecology and forest resources, and which are generally also caused by human activities e.g. by fires spreading into forest from neighbouring agricultural lands. The project aims at further enhancing the use of Earth Observation, Remote Sensing and Simulation modelling in this area of Agri-Tech research and application, whilst also addressing ‘real-world’ issues in relation to Chinese agricultural, landuse and forestry practices.
