“…Such a product was significantly used for modeling (Lopresti et al 2015;Li et al 2013;Zomer et al 2007). The soil erosion was found inversely proportional to NDVI values (Duran et al 2008). The NDVI map for the study area is given in Fig.…”

Trees are an integral part of the sustainable farming practices that can withstand extreme weather events, pest risks, and optimize land and water productivity to achieve food, fuel, fodder and nutritional security while safeguarding the environmental flows. This study was undertaken to analyze the landscape potential for the South Asian region in the geospatial domain utilizing the FAO’s land suitability criteria. The key datasets were derived from satellite remote sensing at a global and regional scale for land, soil, climate, and topography and were used to model the agroforestry suitability across South Asia. Furthermore, the agroforestry suitability categories and tree cover dominance were investigated with respect to the total geographical area, agriculture land cover and with climate variables to understand the present and future trends. The comprehensive analysis revealed that 69% of the total geographical area retains 55% and greater suitability for agroforestry. The analysis revealed that nearly 73.4% of the landscape is absent (0%) of tree cover, 7.1%, shows 1–10% and 19.5% area having more than 10% tree cover. The tree dominance/hotspot analyses in the agriculture land were found notably high in the multiple farming components such as home gardens. The single crop of irrigated and rain-fed croplands showed high land suitability towards agroforestry. Such land can be utilized to enhance the tree cover that suits locally as per the farmer's need based on a community-driven participatory approach to bring the sustainability and resilience in degraded landscapes (FAO in Agroforestry for landscape restoration, 2017). The future climate data analysis showed a significant change in the distribution of temperature and precipitation that will influence future farming practices in South Asia. The agroforestry suitability and tree cover mapping results/analysis will assist crucially the agroforestry policymakers/planners in the various South Asian countries to implement and extend it to the new area. The analysis clearly shows that the advent of big data, remote sensing and GIS provide insights into the agroforestry interventions and scaling which further helps in building resilient landscapes for sustainable agri-food systems, livelihoods, safeguarding the environmental security and supporting some of the important sustainable development goals (SDGs).

“…Soil erosion is a typical environmental problem that inflicts numerous and serious damages in agricultural cultivations as well as in natural ecosystems. In particular, erosion reduces the water-holding capacity of plants due to rapid water runoff and reduces soil organic matter [12], which can also affect green areas (especially those realized in slope surfaces). The key role of plant cover in controlling water erosion is widely accepted.…”

“…The key role of plant cover in controlling water erosion is widely accepted. According to Naylor et al [126], the effects of vegetation on soil can be divided into two major categories: bioprotection, by reducing water runoff [12], and bioconstruction, by increasing water infiltration into the soil matrix [127].…”

“…However, plant leaf area, branch density and ramification can reduce the energy of precipitation (soil impact) of rain and runoffs. The combination of turfgrass, shrubs, and ornamental trees can simultaneously reduce the kinetic force of rain with multiple canopies at different heights and water run-off is slowed down by grass [12]. The reduced superficial run-off velocity increases soil water infiltration exploiting, the channels created by the roots of different species.…”

Biological Contribution of Ornamental Plants for Improving Slope Stability along Urban and Suburban Areas

et al. 2021

Plants can reduce erosion during heavy raining periods and improve slope stability through their root morphology, development, biomass, and architecture. Heavy rains can increase erosion, becoming a danger for traffic and people who live around slopes. The control of slope stability is often required in urban and peri-urban environments, and for this reason ornamental species can be appropriately selected for a dual use, namely improving the aesthetical value of green areas along the urban and suburban roads and mitigating the erosion effects. The species used must have good tolerance to abiotic stresses, such as high and low temperature, drought, pollution and nutrient deficiency. Otherwise, their limited growth can reduce their beneficial effects. Ornamental plants that can be used for reducing the erosion of slopes must be in full growth during periods with a higher incidence of rains and must also be compatible with the temperature ranges in different seasons. These species can be also selected for their ability to avoid erosion and enhance the stability of slopes. In this review, the biological contribution of plants for improving slope stability has been reported and discussed with a special focus attention on the Mediterranean environment. Particular emphasis has been placed on root biomass changes and root growth parameters, considering their role as potential markers for selecting suitable plants to be used for enhancing slope stability. A brief description of planting on slopes and root growth has been also considered and discussed.

“…Among those plants, Lamiaceae are hardy plants able to tolerate cold temperatures, salt stress and drought (Zollinger et al, 2007). They have been used to reduce soil erosion (Durán Zuazo et al, 2008) and could be considered as a vegetation cover for excavated COx heaps. A few publications have shown that pyrite oxidation was reduced in the presence of thymol (Mustin et al, 1992;Meline et al, 1996;Perdicakis et al, 2001).…”

Summary Minerals excavated during industrial activities are stored on the soil surface, exposed to weathering, which leads to the initial development of soil. Plants contribute to soil mineral weathering, mainly by producing acidic or complexing root exudates. In addition, many plants produce antioxidant compounds and phenolic substances that could also contribute to mineral transformation processes, but have rarely been considered in relation to mineral weathering. An incubation experiment was carried out for 2 months under controlled conditions to assess the effects of antioxidant plant metabolites on the weathering processes of a clay mineral. A freshly excavated, sulphur‐rich Callovo‐Oxfordian argillite (COx) sample was artificially leached with three concentrations of three antioxidant compounds (linalool, thymol and carvacrol) or water as a control. The weathering of COx was followed by the analysis of amounts of anions and cations in the leachates. Chlorine, sulphate, nitrate, phosphate, calcium, magnesium and potassium were found in the leachates, whereas iron and aluminium were close to the detection limits. Sulphate leaching reflected oxidation of the pyritic matter contained in COx (mainly fine pyrite particles) by air. Water alone was enough to cause notable leaching of elements such as S and P, but the percentage of leached sulphate increased in the presence of two antioxidant compounds, carvacrol and thymol, and increased to 38% with thymol at 2 mg l−1 compared with the antioxidant‐free control. Thus, antioxidant compounds could contribute to the leaching of elements from COx, depending on their nature and concentration. Highlights We assessed the effects of leaching with antioxidant plant metabolites on COx clay weathering Sulphate leaching reflected the oxidation of pyritic matter (mainly fine pyrite particles) by air Percentage of sulphate leaching increased to 38% with thymol at 2 mg l−1 Antioxidant compounds contribute to the leaching of elements from COx
