Does the Process of Passive Forest Restoration Affect the Hydrophysical Attributes of the Soil Superficial Horizon?

There has been an increase in the area of secondary tropical forests in recent years due to forest restoration in degraded areas. Recent analyses suggest that the success of passive forest restoration is highly uncertain and needs to be better understood. This study aimed to investigate the behavior of saturated hydraulic conductivity (Ks) and some hydrophysical soil attributes between agricultural land uses, restored forests, and a degraded forest fragment. The areas evaluated are located in the municipality of Rio Claro, São Paulo, Brazil, under different types of land use: (i) two areas in the process of passive forest restoration: one of 18 and another of 42 years (NR18 and NR42); (ii) a degraded forest fragment (FFD); (iii) pasture (P), and (iv) sugarcane (SC). The hydraulic soil conductivity characterization was performed using the Beerkan method. Dry soil bulk density (BD), total porosity (Pt), macroporosity (Mac), microporosity (Mic), penetration resistance (PR), mean aggregate diameter (MWD), and soil organic carbon (OC) were also determined. The comparative analysis of the hydrophysical attributes of the soil superficial horizon in agricultural land uses (P and SC), restored forests (NR18 and NR42), and a degraded forest (DFF) confirms that the recovery of soil hydrological functioning in ongoing forest restoration processes can be a relatively slow process. In addition, the intensity of previous land use leaves footprints that can affect passive restoration areas for decades after agriculture abandonment, increasing the time for the recovery of Ks and soil hydrophysical attributes.

Traditional agricultural landscape and their management in less favoured areas in Slovakia

Traditional agricultural landscapes are a mosaic of small-scale arable fields and permanent agricultural cultivations such as grasslands, vineyards and high-trunk orchards. Most of them are threatened by abandonment as they are usually situated in marginal mountain regions with less favourable conditions for agriculture. Our aim was to analyse the distribution of traditional agricultural landscapes in less favoured areas and the effects of the supportive measures of the Common Agricultural Policy, which are oriented towards helping farmers from these areas in maintaining traditional agriculture. Except for traditional agricultural vineyard landscapes, almost all TAL plots are situated in less favoured areas. Most of them are located in mountain areas with less favourable conditions for agriculture. Abandonment of traditional agricultural landscape inside the less favoured areas is significantly higher than in locations elsewhere. The supportive measures of the Common Agricultural Policy do not effectively mitigate this abandonment. If we would like to maintain traditional agricultural landscape in less favoured areas, it is necessary to stop the existing negative trend of abandonment and search for new ways to motivate farmers to continue their traditional farming by adjusting the conditions of the common agricultural policy to benefit small farmers as well.
