Integrated approaches for managing soil erosion in agricultural landscapes: A comprehensive review of conservation strategies, technologies, and implementation frameworks

Abstract

Soil erosion represents one of the most pressing environmental challenges to global agricultural sustainability, threatening food security, water quality, and ecosystem services. This chapter examines integrated approaches to soil erosion management of farm landscapes, synthesising evidence from conservation practices, technological innovations, and watershed-scale interventions. Soil erosion rates are projected to increase by 30-66% by 2070 due to climate change and intensified land use, with annual global economic losses estimated at $8 billion and regional impacts reaching $44 billion in the United States alone. Integrated soil erosion management combines agronomic practices (conservation tillage, cover crops, crop rotation), structural measures (terraces, check dams, riparian buffers), agroforestry systems, and precision agriculture technologies within a watershed management framework. Evidence demonstrates that 40% crop residue cover reduces water erosion by 80%, conservation agriculture improves soil health by 21%, and agroforestry reduces soil loss by 37.7% while increasing system productivity by 162%. Successful implementation requires addressing barriers to adoption, including economic constraints, technical competence, and short-term policy horizons. This chapter synthesises current knowledge on erosion-control mechanisms, the effectiveness of individual and combined practices, the role of emerging technologies, and the policy frameworks necessary to scale conservation adoption. The integration of traditional knowledge with modern remote sensing, variable-rate technology, and adaptive management provides pathways to achieve sustainable soil conservation while maintaining agricultural productivity and ecosystem resilience.
