Overview

Caspar joined University of Queensland's Queendland Alliance for Agriculture & Food Innovation (QAAFI) as a research student in 2013, undertaking his PhD on the intensification of crop production. He had previously studied wheat root distribution after subsoil manuring during his dual degree in agricultural science (honours 1st class) and international development at La Trobe University. His PhD work compared drivers of high yield and their associated risks in smallholder maize production in Mozambique and commercial sorghum production in Queensland. His PhD research was recognised through a number of scholarships and awards, including: a scholarship from the CSIRO’s Sustainable Agriculture Flagship; a Farrer Memorial Trust Travelling Scholarship (2014); and the International Plant Nutrition Institute’s Scholar Award (2015). Caspar was an Australian delegate at the inaugural Youth-Ag Summit in 2013 and a Crawford Scholar in 2015. His work has been featured in COSMOS science magazine and on ABC radio. He currently works as a research officer for the Centre for Plant Science and sits on the Board of Career Harvest.

Research Impacts

Caspar's research has primarily been focused on benefits to the world's poorest people: smallholder farmers. His PhD work led to the identification of ways to improve management practices in farming communities of Mozambique without the need for increased cash investment. Identified changes in management are also able to reduce expsure to seasonal risk (i.e. variable rainfall) increasing yields even in drier years. Caspar has promoted his findings with farmers in Mozambique as well as through several media outlets. In addition to the work in Mozambique, his PhD also identified management options for commercial sorghum farmers in Queensland's Darling Downs region.

Caspar's Post-Doctoral work has included assessing the benefits to soil fertility and structure from adopting conservation agriculture (CA) practices in Zimbabwe. He is currently working on two open source publications describing the diversity of households in Southern and Eastern Africa and pathways to their sustainable intensification.
