Understanding and preventing soil erosion

Description

It’s been suggested that around 12 million hectares of agricultural land are affected by soil erosion each year. If the degradation of the world’s soil reservoir continues, many have estimated that this could lead to a 30% reduction in global food production by 2040.

Understanding and preventing soil erosion provides a comprehensive overview of recent research on understanding the mechanisms of soil erosion, as well as the best practices for measuring, mapping and modelling soil erosion risk in agricultural soils. The book also considers the range of agronomic practices and techniques available to mitigate future soil erosion, including the use of crop residues, cover crops, buffer strips, soil stabilisers and zero/no-tillage.

In its detailed assessment of soil erosion, the book succeeds in highlighting the potential future impact of degraded soils on the quality, security and longevity of our global food system if the problem of soil erosion isn’t effectively managed.

Key features

• Reviews current understanding of the mechanisms of soil erosion, focussing on water-based and wind-based erosion processes
• Considers the effectiveness of mitigation measures to reduce soil erosion, including buffer strips, zero/no-tillage and cover crops
• Addresses recent advances in techniques used to measure, predict, track and model soil erosion, including digital soil mapping and proximal instrumental techniques
