Chapter

Abstract

Drivers of land degradation often co-occur and their effects are often non-additive because of internal system feedbacks. Therefore, to understand how drivers of land degradation alter ecogeomorphic patterns and processes, novel tools are required. In this chapter we explore different modelling approaches that have been developed to simulate pattern formation, and ecological and geomorphic processes. These modelling approaches reflect some of the best available tools at present, but notably, they tend to simulate only one or at best two components of the ecogeomorphic system. The chapter culminates with a discussion of these different modelling approaches and how they provide a foundation upon which to develop much needed ecogeomorphic modelling tools.

Notes

Acknowledgments

This chapter is a contribution to the book Patterns of Land Degradation in Drylands: Understanding Self-Organised Ecogeomorphic Systems, which is the outcome of an ESF-funded Exploratory Workshop – “Self-organized ecogeomorphic systems: confronting models with data for land degradation in drylands” – which was held in Potsdam, Germany, 7–10 June 2010. The research on gap dynamics was supported by grants from the U. S. Army ERDC – Construction Engineering Research Laboratory to New Mexico State University, USDA-ARS and Sevilleta LTER. The development of Mahleran was funded by NERC grant GR3/12754, NSF grants DEB 00-80412 to Jornada LTER and DEB 02-17774 to Sevilleta LTER and support from The University of Sheffield, The Worshipful Company of Farmers, the Royal Society Dudley Stamp Memorial Fund and Rothamsted Research.
