“…The result of this study further shows that all (100.0%) of the respondents practiced ridging because most of the farmers cultivate arable crops like maize, cassava, and yam among other crops, which demands them to make ridges for planting and erosion reduction, hence making it an affordable and useful practice. This finding is in tandem with Akplo et. al (2019) that ridging is significantly adopted and practiced to control soil erosion in the Republic of Benin.…”

Conservation practices are tools used to help conserve and improve natural resources necessary to maintain sustainable arable crop production. This study assessed the extent of use of conservation practices among arable crop farmers in Oyo State, Nigeria. A multistage random sampling procedure was used in selecting 200 arable crop farmers. Data were collected through the use of a structured interview schedule. Percentages and mean statistic were used in presenting the results. Findings showed that the major conservation practices adopted by arable crop farmers were mulching (100%), crop rotation (100%), ridging (100%), bush following (99.0%) and mixed cropping (99.0%). The most frequently utilized conservation practices were ridging (95.0%), mulching (91.0%) and mixed cropping (89.9%). Population pressure on land (𝑥̅=3.77) and availability of funds (𝑥̅=3.74) are factors influencing the effective use of conservation practices. The results further revealed that longterm continuity of yield from land (𝑥̅=2.84), long-term sustainability and productivity of land (𝑥̅=2.76) and increased yields (𝑥̅=2.69) were reasons for conservation practices by arable crop farmers. To ensure improvement in yields, arable crop farmers should be extensively encouraged through access to land and funds to promote the adoption of conservation practices.

“…There is a need to develop simple models capable of quantifying the losses caused by gully erosion, currently measured directly in the field, which is considered a difficult operation to carry out at different spatio-temporal scales (Zapata and Nguyen, 2009;Azaiez, 2016;Mesrar et al, 2017; at different spatio-temporal scales Taylor et al, 2019;Ikenoue et al, 2020;Azaiez and Hamza, 2021;Akplo et al, 2022).…”

“…Since then, investigations into soil degradation have achieved a high level of precision and confidence in the results, particularly after the introduction of the isotope method, which has provided a better quantification of soil losses in the medium and long term (Ben Mansour et al 2012;Porto and Walling, 2015;Mabit et al 2018;Porto and Callegari, 2022). Numerous studies have used isotopic tracers of Caesium-137 and radio-plomb (Pb 210 ) to estimate long-term soil losses (between 22.26 and 30.1 years), and Beryllium-7 to estimate seasonal losses according to crop type and seasonal changes in land use (De Rosas, 2018;Taylor et al 2019;Akplo et al 2022). Most of the studies that used the nuclear approach were based on 1963 as the reference year, particularly for study areas outside the European continent.…”

ONITORING water erosion is a difficult task, due to its complex and variable occurrence in both time and space. Climate forcing, steep slopes and anthropogenic action are the primary factors that can endanger soil resources. Located in the heart of the country's agricultural cradle, the Jīzān region is experiencing a twofold degradation of its land. It is both qualitative in the alluvial plain and quantitative in the mountainous areas. This is why it is so important to find a methodological and experimental framework that is suitable for the local conditions of the wadi Jouah watershed, which has undergone a twofold soil loss quantification. The work was started by applying an empirical model based on the Erosion Potential Model (EPM), followed by careful experimental verification using results from monitoring the Caesium-137 Isotopic Tracer. The specific soil loss was around 35.4 t ha -1 yr -1 according to the EPM equation and around 25.5 t ha -1 yr -1 based on Caesium-137 monitoring. This methodological validation is of crucial importance not only in determining the main sediment-emitting zones and the factors behind slope destabilization, but also in understanding and highlighting the regional context of the erosive dynamics in the intertropical, semi-arid, and mountain regions.
