The mapping and monitoring of land cover, habitats and forest structure through satellite-based observation by government and commercial organisations around the world has been enhanced by data analysis techniques and tools developed by the Earth Observation and Ecosystem Dynamics (EOED) Laboratory at Aberystwyth University (AU). This has allowed new commercial services to be provided and has change professional working practices. The key impacts include (i) improved knowledge and information about land cover and environmental change in forest and brigalow ecosystems in Australia, supporting effective management strategies; (ii) the completion of a comprehensive digital map of habitats in Wales to inform policy-making; and (iii) the increased capacity of the global remote sensing community in forest characterisation using open source software developed by AU.
This case study describes interdisciplinary impacts developed from research of the Sustainable Energy theme. They examine conversion of energy from alternative sources; from power generation using pyrolysis or biomass burners to energy harvesting of waste heat from electronic components. In all cases the aim is clear: to develop systems that make sustainable energy production a reality. This has important impacts in advancing efficiency and reliability in renewable energy technologies. Importantly, through a number of externally funded projects, this group's members have directly influenced local, national and international companies and governmental bodies. In some cases influencing decisions and having direct impact on efficiency, value from investment and even on balance sheets. In summary, they have conducted numerous energy audits, produced a minimum of 6 best practice case studies, influenced the renewable strategies of at least 52 countries, regions or industries and are recognised as the centre for biomass fuel quality assessment.
Impacts: I) Economic benefits derived from carbon credit and land-use schemes in sub-Saharan Africa. II) Multi-national developments in public-policy related to Reducing Emissions for Deforestation and Forest Degradation (REDD). III) Recommendation for launch by the European Space Agency (March 2013) of the first ever forest-specific monitoring mission.
Significance and reach: Public policy developments have occurred over the period 2011 - June 2013 in Malawi, Mozambique and Gabon. Increases of more than 20% in the level of rural employment pre and post 2008 have been documented for one project in Mozambique.
Underpinned by: Research into quantifying tropical forest biomass stocks and their degradation, undertaken at the University of Edinburgh (2004 onwards).
Since 2005 there has been a surge of interest in reducing tropical deforestation as a means of mitigating global climate change, as well as enhancing the protection of tropical biodiversity and contributing to sustainable rural development. Ways of achieving this include the REDD+ (Reducing Emissions from Deforestation and Degradation) within the UN Framework Convention on Climate Change (UNCCC), and also non-governmental ("voluntary") forest carbon sequestration projects being established across the tropics. The Ecosystems Group, led by Malhi, in the Oxford School of Geography and the Environment, has been actively engaged in natural science and policy/governance research directions, all of which have had impacts on both REDD+ and voluntary forest carbon sequestration projects. The group's natural science research has developed scientific methodologies for measuring tropical forest biomass, through in situ plots and satellite imagery, and they have been actively involved in establishing pilot REDD+ projects in several countries. On the policy and governance side, the Forest Governance Group, created in 2009, has played a key role in establishing global databases on the effectiveness of protected areas in conserving forests, provided international comparative analyses of forest policies outside protected areas, and actively engaged in global, regional and local REDD+ policy-making fora.
Yield of valuable biomass fibre components and their utilization in the food industry has been maximised by novel, cost-effective and environment-friendly plant fibre extraction methods developed by BEAA. Specifically, application of these methods enabled patenting and commercialisation of oat fibre extraction by the Swedish company BioVelop, directly resulting in commercial impact through international sales of five nutritional products released since 2010. The most successful of these is produced at a quantity of 180,000 kg, or € 600,000 per year. In May 2013, world-leading food-additive giant Tate & Lyle took over BioVelop, securing the success and lasting commercial impact of the BEAA technology.
Two related research activities 1) on low NOx burners and 2) on co-firing of biomass have led to combined economic savings estimated to be in the region £40M-£70Mpa.
The fitting of low NOx burners to power station boilers reduced the NOx emissions but resulted in a reduced amount of saleable bottom slag and a finer pulverised fuel ash (pfa), which placed an increased load on the electrostatic precipitators. Additions of pfa to the power station coals were found to increase the overall combustion efficiency, while at the same time providing an increased amount of a saleable boiler slag and a pfa that could be used as a cement replacement material.
Despite the very different nature of the ashes produced from the combustion of biomass and coals, a detailed characterisation of the residues demonstrated that, with an appropriate choice of both biomass type and coal, a successful co-firing at up to 50% of coal replacement with biomass was possible. Co-combustion with increased levels of coal replacement has produced significant reductions in power station emissions, resulting in both environmental and economic benefits.
DU researchers have developed new algorithms and statistical models with which to make precise quantitative assessments of forest cover and forest attributes over small or large areas using satellite remote-sensing data, either alone or in combination with airborne or ground-based laser scanning. This research underpins the use of remote sensing as a cost-effective tool for aspects of forest resource management, planning, and policy compliance in many countries. Users include government agencies in the UK, Sweden, New Zealand and Guyana, and international forestry consultancy companies based in Finland with regional branches in New Zealand. DU researchers have also used these methods to help verify the Guyana government's entitlement to $250m under a UN initiative for avoidance of CO2 emissions.
Over the past 10 years there has been a massive expansion in biomass use for power generation, particularly in the UK and Europe. Research at the University of Leeds has been crucial in addressing many of the challenges inherent in moving from coal to biomass including milling, combustion characteristics, deposition and corrosion enabling adoption of biomass for power generation. The research has impacted: (1) company strategy and industry practice for the use of biomass and key technology choices; (2) society, health and environment via CO2 reduction and emission reduction; (3) national energy security through an increased fuel inventory; (4) UK Government and EU policy as expert members of advisory groups.
