Special Issue Information

Dear Colleagues,

Agricultural lands represent more than one-third of the global land surface and are often subject to changes in their land cover and use due to multiple reasons. The conversion of agroecosystems to forest areas, with the objective of restoring degraded croplands and pastures or changing the land use (biofuel production, creation of recreation areas, etc.), is often accompanied by significant changes to soil properties and water fluxes. Many studies have highlighted the beneficial impacts on soil health after afforestation in agroecosystem lands; however, increased water use by tree vegetation is of high concern to policymakers, particularly in areas of water stress. These tradeoffs between the impacts of afforestation on soils and on the hydrological cycle have sparked criticism of implementing man-made forests in land restoration programs and in climate change adaptation and mitigation. This Special Issue aims to further our knowledge about these tradeoffs and the potential of afforestation to improve soil health without endangering water availability.

Potential topics include, but are not limited to, the following:

  • Soil organic carbon;
  • Water loss through evaporation and/or transpiration;
  • CO2, H2O, and CH4 fluxes;
  • Carbon sequestration;
  • Soil organic matter and soil nutrients;
  • Soil erosion and deposition;
  • Infiltration and soil moisture;
  • Invasive plant species;
  • Agroforestry.

Forest expansion in Mediterranean mountain areas is a widespread phenomenon resulting from the abandonment of agricultural and pastoral activities during the last century. Therefore, knowledge of the long-term storage capacity of soil organic carbon (SOC) in Mediterranean forests is of great interest in the context of global change. However, the effects of these land uses and covers (natural secondary forest, afforestation with conifers and silvo-pastoral ecosystems (dehesas)) on SOC dynamics are still uncertain. The main objectives of this study were to evaluate physico-chemical soil properties, SOC and nitrogen stocks, and SOC fractions in Mediterranean forests and to assess the effects of tree species, the soil environment (acidic and alkaline), and land management. We selected five land uses and land covers: managed and non-managed afforestation and dehesa (except for alkaline dehesa) and a stage of succession when tree species begin to become established after abandonment. This study concludes that although total SOC stocks are higher in afforested systems with conifers, SOC is stored in less stable carbon pools than in broadleaf forests. In addition, this study confirms that there are marked differences in the results between acidic and alkaline environments. Finally, the management system is also a significant factor, particularly for afforested sites. Full article
