Plant-soil interactions in Mediterranean forest and shrublands: impacts of climatic change / Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Background: In the Mediterranean climate, plants have evolved under conditions of low soil-water and nutrient availabilities and have acquired a series of adaptive traits that, in turn exert strong feedback on soil fertility, structure, and protection. [...]

Constraints on alluvial clay mineral assemblages in semiarid regions. The Souss Wadi Basin (Morocco, Northwestern Africa) / Elmouden, A. (Université Ibn Zohr. Faculté des Sciences Laboratoire de Géologie Appliquée et Géo-Environnement (LAGA GE)) ; Bouchaou, L. (Université Ibn Zohr. Faculté des Sciences Laboratoire de Géologie Appliquée et Géo-Environnement) ; Snoussi, M. (Université Mohamed V. Département de Géologie)
Illite, chlorite and kaolinite, resulting directly from substratum weathering, dominate the clay assemblages recorded in altered rocks and soils of the Souss Wadi watershed. Nevertheless, the transformation and neoformation of diverse clay minerals, which is mainly controlled by changing climatic, lithological and topographic conditions, enables one to establish three distinctive source areas. [...]

O objetivo deste artigo é a modelagem da dinâmica do uso e cobertura das terras na Bacia-Hidrográfica dos Rios Mogi-Guaçú e Pardo no Estado de São Paulo. Ele foca a restauração dos serviços ecossistêmicos do controle da erosão. [...]
This paper aims at modeling the land use and land cover dynamics in a watershed in São Paulo State, Brazil. It focuses on the potential restoration of the ecosystem service erosion control. The studied watershed is described and its land use and land cover dynamics analyzed, focusing on its main driving forces such as the legislation enforcement and crop relative price changes favoring a very strong expansion of sugar-cane in the region.

Análisis multicriterio de la conservación de suelo : aplicación a una cuenca representativa del centro argentino / Dante de Prada, Jorge (Universidad Nacional de Río Cuarto. Departamento de Economía Agraria) ; Lee, Tsoung-Chao (University of Connecticut) ; Angeli, Ariel Ricardo (Universidad Nacional de Río Cuarto. Facultad de Agronomía y Veterinaria) ; Cisneros, José Manuel (Universidad Nacional de Río Cuarto. Departamento de Ecología Agraria) ; Cantero Gutiérrez, Alberto (Universidad Nacional de Río Cuarto.

La erosión de suelos (ES) es reconocida como uno de los problemas más importantes de la agricultura, con impactos económicos y ambientales dentro y fuera del establecimiento agropecuario en el sur de Córdoba, Argentina. [...]
Soil erosion (SE) is one of the most important problems of agriculture, with economic and environmental impacts: on and off-farm in the south of Córdoba, Argentina. In this paper, the cost on farm of increasing soil conservation (SC) for different scenarios is quantified: in Scenario 1) the farmer knows the cost of SE, in S2) he does not know it, and in S3) he knows it and adheres to the state policy of SC. [...]

"Las cosechas se calcularon en dólares y la tierra se valoraba en capital más interés". Una interpretación crítica desde la Economía Ecológica de la evaluación monetaria de la degradación del suelo / Olarieta Alberdi, José Ramón ; Rodríguez-Ochoa, Rafael (Universitat de Lleida. Departament de Medi Ambient i Ciències del Sòl) ; Ascaso Sastrón, Emilio
El objetivo de este trabajo es discutir las principales aproximaciones utilizadas en la literatura para la evaluación monetaria de la degradación de los suelos: el método del coste de reposición y el método del cambio en la productividad. [...]
The main approaches used for the monetary evaluation of soil degradation, the replacement cost and the change in productivity approach, are discussed. The replacement cost approach has been applied to soil erosion processes mainly, and represents soils as mere stocks of plant nutrients. [...]
