    Professor Richard Harper
    B.Sc. Agric. (Hons), PhD

    Professor

    About me

    Richard Harper is a Professor in the Food Futures Institute. His research is devoted to devising new approaches to soil, water and biodiversity management; an area where globally there are many long-standing and intractable problems. A particular focus has been on using carbon mitigation investment to drive landscape-scale change; this also dealing with increasing global greenhouse gas emissions and meeting ambitious emissions reduction pledges from governments and industry. A parallel program is investigating soil water repellency, which causes problems in many environments.

    He joined Murdoch in 2009, following twenty years science and policy experience with the Western Australian Government in programs addressing salinity, plantation and farm forestry and climate change mitigation. He has a B.Sc. Agric. (Hons) and PhD (Agriculture) (UWA).

    His research program currently comprises 6 PhD students and a range of Murdoch, national and international collaborators. Recent publications have explored both the science and policy aspects of climate mitigation, using bioenergy or sequestration in plants and soil. Some recent highlights include exploration of carbon stores in soils to depths of 37 m, novel bioenergy production systems, and consideration of how to gain water and biodiversity benefits from carbon reforestation projects. His work has ranged across agricultural land, plantation and natural forests, rangelands and near-shore environments.

    He was a lead author on the 2014 IPCC Fifth Assessment Report (WGIII) chapter on mitigation using Agriculture, Forestry and other Land-Uses (AFOLU). He is the current co-chair of the International Union of Forest Research Organization (IUFRO) Taskforce on Forests and Water, a member of the Australian Government’s Threatened Species Scientific Committee, a visiting Professor with the Chinese Academy of Forestry, an associate editor of Soil Research and past President of the Australian Council of Agricultural Deans. His undergraduate lectures are in soil science, climate mitigation and hydrology.
