“…Only then does a differentiation between hazard and vulnerability, between present degradation status and future risk become possible, thereby promoting a better understanding of risk and an identification of effective entry points for DRR measures (Cardona 2004, Hessel et al 2014, Masoudi et al 2021b. Stating the respective perspective on land degradation (e.g., which definition is used) helps to establish clarity about what is actually perceived as a risk.…”

“…Several studies (namely: Salvati and Zitti 2009, Santini et al 2010, Becerril-Piña et al 2015, Salvati et al 2015, Tombolini et al 2016, Vorovencii 2016, 2017, Weinzierl et al 2016, Karamesouti et al 2018, Masoudi et al 2021a, 2021b consider temporal trends in their analysis, thereby accounting for the dynamic nature of land degradation, as well as for the potential of future risk. Santini et al (2010:395) point out in their introduction that "an area mildly degraded subject to an intense and rapid desertification process is more at risk when compared to an area at higher degradation level but stable over time."…”

“…Martínez-Valderrama et al (2020) used a state and transition model of social-ecological systems and assessed risk based on the percentage of simulations in which the final stable state was undesirable (key resources exhausted or critical thresholds crossed). Three studies (Masoudi and Jokar 2018, Masoudi et al 2021b, 2021a clearly distinguish between the present degradation status (termed "actual risk" in Masoudi and Jokar 2018) and "potential risk" of degradation in the future. Furthermore, they introduce a statistical picture of risk by assigning probability levels to those areas at potential risk of becoming further degraded in the future.…”

“…Usually, land degradation is treated as either permanent or a discrete hazard. However, some studies (Ibáñez et al 2008, Ubugunov et al 2011, Masoudi and Jokar 2018, Martínez-Valderrama et al 2020, Masoudi et al 2021a, 2021b do include a probabilistic element of risk, facilitating a distinction between present degradation status and future risk. Two of those studies (Ibáñez et al 2008, Martínez-Valderrama et al 2020) are based on scenario analyses in state and transition models.…”

Land degradation adversely affects the well-being of approximately 3.2 billion people worldwide and results in a loss of about 10% of annual gross domestic product. Degradation dynamics are often creeping and non-linear, hence the adverse consequences are often not immediately perceived. In consequence, methods for assessing future risks of land degradation and risk reduction strategies are trailing far behind those that have been developed within disaster risk research for natural hazards that appear as shocks, such as floods or earthquakes. Therefore, the objective of this paper is to analyze existing land degradation risk assessment approaches to assess what is hindering a link to land management strategies. The synthesis presented here reveals that while approaches to calculate land degradation risk have evolved to capture ever more processes and factors involved in land degradation, no consistent conceptual framework for land degradation risk has been developed to the present day. Key identified short-comings are that risk terminology is not consistent across and within studies and that there is often no distinction between a degradation status assessment and an assessment of future risk. Damage is rarely explicitly considered or quantified, and in the majority of studies there is no clear distinction between processes and drivers, hazard and vulnerability. Finally, novel conceptual ideas integrating the risk framework developed within disaster risk research are proposed to stimulate debate and facilitate the development of effective risk reduction measures for land degradation.

Land degradation (LD) is a severe and well‐known global concern. Therefore, this review aimed to find broader connections between LD and the Sustainable Development Goals (SDGs). This literature review aims to synthesize the definitions, processes, assessments, and challenges associated with LD. Furthermore, we developed a universally applicable and concise definition of LD that links a wide range of contexts and studies. Specifically, we categorized LD‐related processes into physical, chemical, and biological processes and synthesized 20 methods/formulas used in the assessment of LD. Finally, we synthesized the most significant challenges in the context of the resolution of LD and provided corresponding recommendations. The review also identified the main SDG targets that LD directly affects and the role of LD in relation to the SDGs. Overall, we expect this literature review to be a valuable resource for researchers and practitioners aiming to obtain a comprehensive understanding of LD. The findings of this study shed light on various aspects of LD concerning the SDGs. The LD and the SDGs' processes, challenges, and interactions can be a valuable resource for researchers and policymakers. The information can facilitate sustainable and scientifically rooted use of land resources and provide knowledge and advice on combating LD to reach the specific SDGs associated with LD.

This study aims to assess the amount of organic carbon stored in soils, as it is an intention of knowing the sustainable soil management, by using two common methods for determining soil organic matter (SOM), namely oxidation with acidified wet dichromate (Walkley–Black method-WB) and loss on ignition (LOI). The study was carried with soil samples collected from a depth of 0 to 30 cm in the Saharan arid region of Ghardaïa (Algeria), with different land uses: agricultural, forest and pastoral. The results obtained from the LOI and WB methods were subjected to statistical analysis, and the relations between both methods were tested to investigate their relationship. The mean percentage of SOM values were 1.86, 2.42, 1.54 by using LOI, but, lower values of 0.34, 0.33, 0.36 were determined by using WB method, for agricultural, forest and pastoral soils respectively. A weak linear relationship between the two analytical procedures was obtained (R2 of 0.19 and 0.13 for agricultural and forest soils), while a medium relationship (R2 = 0.65) was found for pastoral soils when using linear adjustment. However, the opposite behaviour was found when we use the logarithmic adjustment. The study outcomes indicated discrepancies in the measurements of SOM values between the two methods, been higher those estimated with LOI. Finally, in order to identify the best methodology to measure soil organic matter in arid soils, more research is required in these extreme arid regions as they are a gap in world soil organic matter maps.
