“…Furthermore, the recent advances in sensor science support the innovation potential by exploiting the multiple research and operational assets in soil spectroscopy domain to effectively monitor SOC stocks for accounting purposes [110]. By that means, the generally low SOC content could ultimately increase via the adoption of appropriate management practices [111].…”

Remote Sensing Techniques for Soil Organic Carbon Estimation: A Review

Towards the need for sustainable development, remote sensing (RS) techniques in the Visible-Near Infrared–Shortwave Infrared (VNIR–SWIR, 400–2500 nm) region could assist in a more direct, cost-effective and rapid manner to estimate important indicators for soil monitoring purposes. Soil reflectance spectroscopy has been applied in various domains apart from laboratory conditions, e.g., sensors mounted on satellites, aircrafts and Unmanned Aerial Systems. The aim of this review is to illustrate the research made for soil organic carbon estimation, with the use of RS techniques, reporting the methodology and results of each study. It also aims to provide a comprehensive introduction in soil spectroscopy for those who are less conversant with the subject. In total, 28 journal articles were selected and further analysed. It was observed that prediction accuracy reduces from Unmanned Aerial Systems (UASs) to satellite platforms, though advances in machine learning techniques could further assist in the generation of better calibration models. There are some challenges concerning atmospheric, radiometric and geometric corrections, vegetation cover, soil moisture and roughness that still need to be addressed. The advantages and disadvantages of each approach are highlighted and future considerations are also discussed at the end.

“…For example, when considering climate data, several analysis (Jones et al ., ; Gobin & Govers, ) clearly showed that the values of essential precipitation characteristics, such as total annual precipitation, that were derived from the databases available at the European scale for Italy can deviate considerably (>50%) from more accurate estimates based on locally available data. A systematic soil survey of the Mediterranean region obtained by using the most updated technology and scientific knowledge is still lacking for site‐specific adaptation for local mitigation strategies and should be a priority in the near future (Lagacherie et al ., in press). Indeed, the sparseness of the legacy soil data available in the current soil databases has hampered the capture of short‐term soil property variations within the complex patterns of Mediterranean soil.…”

“…The Mediterranean region has a very long history of intense cultivation (De Franchis & Ibanez, ; Roose, ) with a unique combination of relief, climate conditions, soil forming factors and parent materials (Yaalon, ). Consequently, Mediterranean soils are very different from the soils in other regions in the world (Lagacherie et al ., in press). Conservation and management of Mediterranean soil resources have strongly contributed to the spread of successive civilizations in the past.…”

Soil resources are important for the socioeconomic development of the Mediterranean area. Their durability may be threatened because of intense erosion processes that result in severe degradation in the field (on‐site effects) and downstream degradation (off‐site effects). Based on the literature and results obtained during several research projects, this paper presents the main lessons and challenges dealing with Mediterranean soil resources under global change. After a review of the main drivers of Mediterranean soil erosion and the main impacts of water erosion processes, the paper highlights that the nature and intensity of active erosion processes are as diverse as the mosaic of the Mediterranean landscape. It then discusses the expected evolution of Mediterranean soil resources under global change and illustrates the prevalent influences of land use (partly depending on climatic constraints) on the evolution of erosion risk and soil vulnerability. Finally, it details some main challenges for the future of Mediterranean soil resources dealing with a better knowledge of factors and processes involved in soil erosion, a better evaluation of soil vulnerability through a combined quantitative and qualitative soil erosion approach, and the need for a site‐specific conservation strategy for Mediterranean soil resources.

“…Around the world, conventional agriculture requires soils tillage twice a year before cereals sowing to control weed and to prevent crust formation. However, these practices added to climate change and soils vulnerability engendered erosion [4], soil moisture loss and soil organic matter reduction [5]. Consequently, conservation agriculture appeared such an alternative to conventional agriculture.…”

One of the proposed solutions to face climate change impact and to maintain food production sustainability is conservation agriculture. This study tries to determinate the effect of conventional tillage (CT) and no tillage (NT) on secondary metabolites such as total phenolics content (TPC), total flavonoids content (TFC) and antioxidants capacity (DPPH %) in relation to natural mycorrhization of durum wheat during the tillering stage for three cultivation years. The experiment was conducted in a referential farm (Krib, Siliana, North West Tunisia). The results showed that TPC, TFC and DPPH% were not influenced by tillage system (T). However, cultivation year (Y) had a significant effect on the studied parameters independently of tillage system. In addition, for the first cultivation year, tillage system (T) had significantly influenced the mycorrhization rate (MR%) and NT presented the highest mycorrhization rate (24%). DPPH% showed high significant positive correlations with MR% and TPC. For partial correlation based on Tillage system, high positive correlations were noted between DPPH%, MR% and TPC. Considering the partial correlation based on cultivation year, only a significant positive correlation between TPC and TFC was observed. In conclusion, durum wheat quality was not affected by tillage system and there are not reasons against no tillage adoption in this region for a sustainable wheat production.
