Recent studies affirm that climate change is affecting areas worldwide, particularly long droughts, which would transform many fertile territories into degraded areas. This could imply significant impacts and natural hazards influencing both water and soil resources and, subsequently, plant species composition and biodiversity. One of the affected land use and related type of ecosystem are the pastures of the hills with small ruminants (sheep and goats). However, there is a lack of studies aimed to develop integrated hydrological and climate approaches to assess these possible impacts in countries such as Romania. Therefore, this study aims to evaluate drought impacts on hills pastures occupied by small ruminants (SRs) based on the analysis of aridity indices, rainfall simulation experiments, and field surveys (e.g., soil profiles and vegetation transects) in an experimental plot located in the Curvature Subcarpathians of Romania. Preliminary results show high monthly variability of aridity, vertical dehydrated layers in the main soil types (chernozems exhibiting shrinkage and swelling processes), degraded herbaceous vegetation, and high runoff coefficient for bare soils. At the hillslope scale, vegetation, SRs, and water occurrence (e.g., low runoff coefficients and high infiltration rates) are strongly affected by droughts, especially during August and September. The intensification of SRs grazing in these areas (under dry conditions) amplifies the drought effects on the environment (e.g., soil compaction, grass depletion, water scarcity). Our field observations do not support SRs grazing as a major driving factor for land degradation, but unsustainable SRs grazing can drastically induce changes in seasonally available soil water content under arid conditions.

This work aims to review the existing theoretical literature and experiments on plant species colonising gaps after soil disturbance. It attempts to evaluate the various mechanisms by which plants regenerate among the soil openings within the Mediterranean temporary ponds. Intensity and frequency of disturbances are key factors in the response of communities. Knowing the specificity of plant strategies and the species assembly process is important for a better understanding of the impact of soil disturbance on the structure of temporary ponds community, and their mechanisms of resilience. Under the scope of these mechanisms, we will assess the contribution of seed bank by regrowth of buried seeds, vegetative propagules growth via clonal propagation and dispersion of propagules. Soil disturbance has a biotic effect on competition giving a chance to competitively inferior species.

Land use/land cover changes (LULCC) at Adei watershed (Ethiopia) over a period of 23 years (1986–2009) has been analysed from LANDSAT imagery and ancillary data. The patterns (magnitude and direction) of LULCC were quantified and the final land use/land cover maps were produced after a supervised classification with appropriate post-processing. Image analysis results revealed that the study area has undergone substantial LULCC, primarily a shift from natural cover into managed agro-systems, which is apparently attributed to the increasing both human and livestock pressure. Over the 23 years, the aerial coverage of forest and grass lands declined by 8.5% and 4.3%, respectively. On the other hand, agricultural and shrub lands expanded by 9.1% and 3.7%, respectively. This shows that most of the previously covered by forest and grass lands are mostly shifted to the rapidly expanding farm land use classes. The findings of this study suggested that the rate of LULCC over the study period, particularly deforestation due to the expansion of farmland need to be given due attention to maintain the stability and sustainability of the ecosystem.
