Knowledge for a sustainable world

BAgric Hons, PhD

Dr Onoriode Coast joined the University of Greenwich in 2020 as a Senior Fellow of Crop Physiology. He has extensive research experience in Australia, Nigeria, the Philippines, UK and USA.

Prior to joining NRI, Coast was a Research Fellow at the Australian National University (ANU), Canberra, working within the Australian Research Council Centre of Excellence in Plant Energy Biology. At ANU Coast worked on a number of crop physiology and plant ecology projects, including developing a high-throughput system for remotely estimating leaf dark respiration, photosynthetic thermal tolerance in crops, acclimation of photosynthetic and respiratory processes in wheat, and a global review of plant thermal tolerance research.

Coast was a Postdoctoral Fellow at Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) from 2013 to 2016. Based at the Australian Cotton Research Institute, Narrabri, Coast developed a novel canopy temperature-based irrigation scheduling system for furrow-grown cotton crops. This irrigation system has been commercialised by CSIRO and the Australian Cotton Research and Development Corporation, and its use extended to other cropping systems in Australia. Coast previously held academic positions at the University of Benin, Nigeria.

Coast was awarded a prestigious Felix Scholarship, the only sub-Saharan African recipient of the award in 2009, after graduating with First Class Honours in Crop Science from the University of Benin, Nigeria. This enabled him to investigate the physiological basis of high night temperature tolerance in rice for a PhD at the University of Reading. Coast is an Associate Fellow of the Higher Education Academy, and has mentored and supervised graduate and undergraduate students.

Dr Coast’s research interest spans the fundamental and applied aspects of crop science. From understanding crop responses to environmental changes to improvement of cropping systems for better crop yield. Other areas of interest include identifying natural variation in plant stress resilience, field experimentation, data analysis, and the development of phenotyping techniques for plant eco-physiology research.

‘Photosynthetic acclimation to high temperature in wheat.’

The economic losses from heat damage on Australian wheat is estimated at over $1 billion per annum. This project aimed to broaden the focus and potential impact of a national heat stress project (A national approach to improving heat tolerance in wheat through more efficient carbon allocation) by (i) investigating photosynthetic acclimation to high temperature and its associated energy cost, an important physiological process whose limitation by heat stress severely affects yield, and (ii) fine-tune the development of a high-throughput screening technique for photosynthetic heat tolerance that pre-breeders and commercial breeders could incorporate in their toolbox for selecting better lines for eventual delivery to growers.

‘Applying plant based measurements for irrigation in water limited environments.’

There is significant gap between the average industry yield and the top achievers in irrigated cotton industry of Australia. This gap can be reduced significantly by improving irrigation efficiency. This project extended the canopy temperature-based approach of irrigation scheduling to furrow systems by developing a tailored stress time threshold for Australian cotton production system. Adoption of this irrigation approach could help boost confidence of irrigators and improve irrigation scheduling of the average cotton grower as it is based on continuous monitoring of plant stress in real time.
