Abstract

With particular reference to publications from the last few years, this report focuses on a selection of emerging research themes that highlight the growing links between arid geomorphology and other disciplines, including ecology and soil science, sedimentology and petroleum geology, and planetary science. Three themes are addressed : 1) the role of fire in arid geomorphological systems, characterized by investigations that tend to focus on surface processes and landforms at relatively small spatial scales (plot to short channel reach) and short timescales (hours to years); 2) arid fluvial sedimentary systems, characterized by investigations that commonly focus on processes, landforms and sedimentary products at larger spatial scales (channel reach to basin) and longer timescales (years to millions of years); and 3) arid geomorphology on Mars, commonly characterized by process-landform investigations at very large spatial scales. For each theme, research gaps are identified, which provides an indication of where the research frontier currently lies
