“…From an ecological perspective, species richness provides an instantly comprehensible expression of diversity, provided that care is taken with sample size (all sample sizes must be equal) (Saldaña et al . ). Therefore, if we are able to divide the study area into a regular network and we have been able to identify all the classes on a certain scale within every area of that network, richness estimates will provide us with a useful value for diversity (Ibáñez and García‐Álvarez ).…”

Mid-and large-scale geodiversity calculation in Fuentes Carrionas (NW Spain) and Serra do Cadeado (Paraná, Brazil): methodology and application for land management.ABSTRACT. A state-of-the-art geodiversity concept, its use and scientific development are presented. Methodologies for geodiversity calculation are assessed, as well as their aim and problems. Geodiversity calculation methodology based on biodiversity richness index is explained and applied to two different areas: Fuentes Carrionas, a high mountain midlatitude environment in northern Spain, and Serra do Cadeado, a tropical mid-mountain environment in southern Brasil. A geodiversity map of Fuentes Carrionas proves that glacial cirques over 2000 m a.s.l. keep a high geodiversity related to a periglacial and glacial environment, whereas a geodiversity map of Serra do Cadeado shows that high geodiversity areas are situated at its main structural scarp. Geodiversity calculation needs to take scale and hierarchy issues into account, which makes comparison only possible if the same scale is used. Geodiversity calculation is a useful tool for land management as it defines areas subject to protection due to the richness of abiotic elements. It is also useful in terms of environmental impact assessment and geotourism evaluation at remote areas.

Gully erosion is a particularly damaging process which is not yet sufficiently understood and parameterized. Gully head topographic threshold relative to Hortonian runoff have been studied in cropland, rangeland and forest. This study extends such modelling approach to badlands. Different badlands (eight sites) have been studied in the Mediterranean environment in Italy and Spain, characterized by diversified climatic, lithological, and geological settings under different anthropogenic conditioning. Many badlands have been characterized by their specific human history in addition to their geomorphological properties. Land use, as part of the human history, strongly affected many badland formation and development, through extremely impacting land exploitation (usually overgrazing). The effect of geological and geomorphological processes are usually particularly well visible. While the weakening effect of joints is confirmed, the different geological layer bedding orientation with respect to the slope aspect generates a different development of badland morphologies and different values of gully head thresholds values (as shown in two badlands sites on the same geological material and climate.The selection of Curve Number values, at the base of the introduction of land use into the gully head thresholds, has been more objectively defined in order to reduce arbitrariness in threshold application. The study additionally revises some of the physical basics behind the gully head threshold concept, requiring a description of the soil resistance in terms of frictional and cohesive components. This implies the explicit inclusion of rock fragment into the grain size distribution, which cannot be limited to fine grains. It results into an enriched threshold formulation that allows to describe the condition for gully head initiation and retreat as the result of the tradeoff between the frictional and cohesive components of the soil resistance forces.Eventually, the gully head threshold concept is confirmed and extended to include badlands.

“…This area is dominated by weakly alkaline and viscous cinnamon soil, which features the leaching and deposition of calcium. Due to the accumulation of clay particles, the soil is rich in calcium carbonate, over 80% in base saturation, saturated with calcium ions, and poor in organic matter [11,12].…”

This paper attempts to identify the content distribution of heavy metals in the soil around a construction waste landfill, and evaluate their impacts on human health. Firstly, parallel samples were collected from the soil in the study area. Then, seven heavy metals, namely, Fe, Cr, Pb, Cu, Hg, As and Cr, in the soil samples were detected and tested by inductively coupled plasma emission spectrometry, inductively coupled plasma mass spectrometry, and atomic fluorescence photometry, and the vertical distributions of these heavy metals were determined. After that, the cumulative risks of heavy metals in the soil were evaluated by single index method and Nemerow index method. Finally, these heavy metals were subjected to health risk analysis. The results show that the vertical distribution of Cu changed significantly in the soil around the landfill; the cumulative pollutions of Fe, Cu, and Hg in the soil reached the heavy level; the non-carcinogenic risks of As and Cr are relatively high, while Cr poses a carcinogenic risk to the human body. The research results provide effective data support to the site selection and operation of construction waste landfills.
