Prof. Balzter received the degree of Dipl. Ing. agr. (equivalent to MSc) from Justus-Liebig-University, Giessen, Germany, in 1994 and the Dr. agr. (PhD) from the same University in 1998. He is a research professor and Director of the Centre for Landscape and Climate Research at the University of Leicester and a Co-Investigator in the NERC National Centre for Earth Observation. Prof. Balzter holds the Royal Society Wolfson Research Merit Award (2011) and the Royal Geographical Society’s Cuthbert Peek Award ‘for advancing geographical knowledge of human impact through earth observation’ (2015).

After his PhD, Prof. Balzter worked in the Centre for Ecology and Hydrology, Monks Wood, from 1998-2006, as Radar Remote Sensing Specialist, Head of the Biophysical Modelling Group and later Head of Section for Earth Observation. He was appointed to the Chair in Physical Geography at the University of Leicester in 2006 and served as Head of Department of Geography from 2008-2011.

Prof. Balzter is a member of the NERC Food Security Evaluation Working Group, the Steering Committee of the NERC Airborne Remote Sensing Facility, and the AIRSAR Steering Board for the Satellite Applications Catapult and Airbus Defence and Space. He was Principal Investigator of the European Centre of Excellence in Earth Observation Research Training GIONET (€3.5m), and is involved in a broad research programme as principal or co-investigator, including the ESA project GLOBBIOMASS.

Research Interests

The Centre for Landscape and Climate Research

I am director of the Centre for Landscape and Climate Research which specialises in research in field of Spatial Ecohydrology for monitoring of biophysical ecosystem services and natural capital. This involves investigating the complex interactions of the water cycle with biogeochemical cycles and plants and animals in ecosystems. We use ground-based, airborne and spaceborne remote sensing, geospatial analysis methods, high-performance computer model simulations and field survey techniques.

Research in the Centre currently focusses on Earth observation for biodiversity and ecosystem services, pioneering the uses of satellite and other data to measure the spatial patterns and temporal dynamics in ecosystem services provision. Remote sensing of forests and agricultural systems for climate mitigation and food security form the core of this research.

My research focuses on contemporary environmental change processes related to climate change and human impacts on biogeochemical cycles and biophysical systems. As a result of a combination of natural and human-induced processes, climate change is occurring at unprecedented speed. Climate change as a global challenge requires a reliable global monitoring and forecasting system to deliver information that policy makers and business leaders can trust. Satellite remote sensing systems are now delivering operational observations from space that have revealed unknown features of Planet Earth.

A key unknown at present is the role of feedbacks between different Earth system components in determining future trajectories of climate change. In order to better understand land/atmosphere interactions, I am pursuing the following research areas:

Remote sensing of forests

Forest ecosystems play a crucial role in global biogeochemical cycles and in stabilising the climate system. Through heterotrophic and autotrophic respiration and fires they release greenhouse gases to the atmosphere and through photosynthetic carbon sequestration they reduce the atmospheric fraction of carbon dioxide. Deforestation is thought to be a major contributing factor to global anthropogenic carbon emissions. Global initiatives such as REDD+ (Reducing Emissions from Deforestation and Degradation) aim to protect forest resources in support of climate mitigation policies. The geographic locations and strengths of global terrestrial carbon sources and sinks and their temporal variability are still subject to much speculation. I have developed Synthetic Aperture Radar (SAR) and LIDAR techniques for mapping forest canopy height and forest biomass. I am principal investigator in many satellite data exploitation programmes including TerraSAR-X, Tandem-X, Disaster Monitoring Constellation, ENVISAT, ERS-1/2, Sentinel-1 and 2, JERS-1, NovaSAR-S, ALOS and ALOS-2. The paper in Nature by Lynch et al. (2013) makes the case for radar satellites for forest monitoring.

I have had a long-standing involvement in the Copernicus programme that established the European land monitoring core service. In 2014 my group completed the delivery of the UK CORINE land cover map 2012 for the GIO-Land programme. New methods of using radar data from Sentinel-1 were also tested (Balzter et al. 2015). Some of our forest-related research is co-funded by industry, for example on tree disease mapping from airborne data and on forest biomass mapping.

I am scientist-in-charge of the European Centre of Excellence for Earth Observation Research Training “GIONET” (Marie Curie programme, €3,500,000, 2011-2015), which has trained 14 researchers over 4 years in land monitoring and emergency information services from space. In the ESA project GLOBBIOMASS, which has the aim to produce a global forest biomass map, I am leading the task on Regional Case Studies.

The study by Arellano et al. (2015) is one of the top 25 most downloaded papers from Environmental Pollution. It found that remote sensing can detect oil pollution underneath dense rainforest canopies in the Ecuadorian Amazon.

Land/atmosphere interactions

The land surface interacts with the atmosphere through the exchange of carbon, water and energy, and feeds back to climate change processes. Two eddy covariance flux towers on lowland peatland in the East Anglian Fens are continously measuring carbon, water and energy fluxes under different land uses. In my recent paper in the journal Climate (Balzter et al. 2015) we found subtle changes in the temporal scales of variability of Central European air temperature anomalies since 1960 in comparison to the earlier period from 1850-1960, using a technique called Multi-Scale Sample Entropy analysis. This method is able to detect changes in time-series data that are invisible to other standard data analysis methods.

A method for monitoring environmental land condition at continental scale for Africa was devised in our paper by Hoscilo et al. (2015). It found significant drying / wetting trends and greening / browning trends for several regions in Africa and attributed them to climatic and non-climatic drivers.

A study by Rasul et al. (2015) in Urban Climate diagnosed a night-time urban heat island effect and day-time urban cool island in the city of Erbil in the Kurdistan region of Iraq.
