A Review of Landscape Design as a Means of Controlling Gully Erosion

Gully erosion is the most visible and devastating form of soil erosion known to be one of the leading causes of land degradation worldwide. Landscape design is one of the techniques used in combating this problem. The objective of this paper is to review the use of landscape design in controlling gully erosion. The method used is a review of academic articles, conference papers, internet materials, textbooks and publicly available materials on landscape design and gully erosion. The results of this study indicated that previous authors whose works were reviewed have a convergent view that the use of vegetative approach, an aspect to landscape design, must be practiced for effective control of gullies. On the other hand, however, previous authors have divergent views on the use of structural approach, another aspect to landscape design, for control of gully erosion. Recommendations of this study include: (1) planting of a combination of woody trees and grasses; (2) use of some locally accessible structures for example, sieve structures; and (3) practise of agroforestry.
