Water erosion, soil organic carbon redistribution and soil and water conservation: a review

Abstract

[ES] Introducción: La pérdida de suelo por erosión hídrica influye en los flujos positivos y negativos de carbono hacia la atmósfera. Objetivo: Identificar las principales tendencias de investigación con respecto a la influencia de la erosión hídrica en la redistribución del carbono orgánico del suelo (COS) y su relación con las prácticas de conservación del suelo y agua. Materiales y métodos. La literatura publicada en revistas nacionales e internacionales se consultó en Web of Science, Scopus, SciELO, Redalyc, ResearchGate y Google Académico. Mediante palabras clave predefinidas se analizaron las tendencias de investigación y se agruparon según su afinidad. Resultados: En el periodo 2012-2022, 80 % de la investigación global se enfocó en la redistribución del COS por efecto de la erosión hídrica y en el efecto del manejo del suelo y de las prácticas de conservación; sin embargo, no se encontraron trabajos al respecto en México. Debido a la erosión hídrica, en México se han implementado programas para la construcción de obras de conservación de suelos y aguas con éxito significativo, como las presas de control de sedimentos, pero no se han evaluado los impactos en términos del almacenamiento de C. Conclusiones: En México existen áreas de oportunidad para enfocar la investigación a diferentes escalas: (I) analizar la redistribución del COS por efecto de la erosión hídrica, (II) estimar el almacenamiento del COS en sedimentos, (III) analizar el potencial de prácticas mecánicas de conservación de suelo y agua como sumideros de carbono y (IV) proponer un índice de riesgo de pérdida del COS utilizando sensores remotos

[EN] Introduction: Soil loss caused by water erosion impacts both positive and negative fluxes of carbon to the atmosphere. Objective: To identify the main research trends related to the influence of water erosion on soil organic carbon (SOC) redistribution and its relationship with soil and water conservation practices. Materials and methods. Literature published in national and international journals was consulted in Web of Science, Scopus, SciELO, Redalyc, ResearchGate and Google Scholar. Research trends were analyzed using predefined keywords and grouped according to their affinity. Results: In the period 2012-2022, 80 % of global research focused on SOC redistribution caused by the effect of water erosion and the effect of soil management and conservation practices; however, no studies were found in this regard in Mexico. Due to water erosion, programs for the construction of soil and water conservation works have been implemented in Mexico with significant success, such as sediment control dams, but the impacts in terms of C storage have not been evaluated. Conclusions: In Mexico there are areas of opportunity to focus research at different scales: (I) analyze the redistribution of SOC caused by water erosion, (II) estimate the storage of SOC in sediments, (III) analyze the potential of mechanical soil and water conservation practices as carbon sinks, and (IV) propose a risk index of SOC loss using remote sensing.
