Wild boar ( Sus scrofa ) is a widespread megaherbivore that can intensively disturb large areas of its habitat both in its native and non-native ranges, when populations reach high densities. The main problem is its rooting habit, which entails intensive disturbance of the topsoil and herbaceous layer. The extent of concomitant habitat degradation varies across ecoregions; some ecosystems are rather resilient, although the damages are long-lasting in others. In mown meadows, a secondary problem is the inability to resume mowing due to the uneven soil surface of rooted patches. This can lead to both economic loss and a loss of management-dependent biodiversity. We assessed the short-term effects of rooting on vegetation cover and composition in central European permanent hay meadows and tested the utility of manual soil surface resmoothing to enable the continuation of mowing. We found that rooting increased bare soil surface but vegetation recovery occurred within a year. Similarly, high resilience was found for species composition. We could not detect any difference between rooted and intact grassland patches after 1 yr. This short-term perturbation of the composition could be associated with a temporary decrease in grassland specialist species and an increase in ruderal and pioneer species. Soil surface resmoothing was an additional disturbance, but vegetation cover returned to the level of intact grasslands within a year. Vegetation composition needed a slightly longer time (2 yr) to recover than that without resmoothing. We thus recommend the application of manual resmoothing in hay meadows with high short-term resilience to rooting, but a risk of long-term degradation (e.g., shrub encroachment) if mowing is not resumed. In hay meadows with lower resilience (because of, e.g., steep slopes), resmoothing should be applied with caution and may be supplemented with seeding to support the recovery of the vegetation and prevent soil erosion.

Wars have serious negative effects on the total environment. This study reviews 193 case studies worldwide in order to better understand these impacts and their potential management before, during and after war. The synthesis of the evidence shows that military actions damage landscape resources. Aerial bombings have great negative impacts by damaging environmental conservation efforts, destroying trees, disturbing soilscapes and undermining soil health. In addition, war exterminates wildlife and their ecological niches and contributes to atmospheric and water pollution. Overall, military leaders and personnel have shown little concern about these impacts. Limited postwar restoration activities are also undertaken to reduce war-driven environmental impacts. The study highlights some good practices on how to manage the total environment during the warfare. Therefore, communities must share best lessons to remain in a sustainable peace, restore the war -damaged environment, and enhance sustainable economic development.

Root reinforcement, provided by plants in soil, can be exerted by a mechanical effect, increasing soil shear strength for the presence of roots, or by a hydrological effect, induced by plant transpiration. No comparisons have been still carried out between mechanical and hydrological reinforcements on shallow slope stability in typical agroecosystems. This paper aims to compare these effects induced by sowed fields and vineyards and to assess their effects towards the shallow slope staibility. Root mechanical reinforcement has been assessed through Root Bundle Model-Weibull. Root hydrological reinforcement has been evaluated using an empirical relationship with monitored or modelled pore water pressure. Each reinforcement has been inserted in a stability model to quantify their impacts on susceptibility towards shallow landslides. Considering the same environment, corresponding to a typical agroecosystem of northern Italian Apennines, land use has significant effects on saturation degree and pore water pressure, influencing hydrological reinforcement. Root hydrological reinforcement effect is higher in summer, although rainfall-induced shallow landslides rarely occur in this period due to dry soil conditions. Instead, in wet and cold periods, when shallow landslides can develop more frequently, the stabilizing contribution of mechanical reinforcement is on average higher than the hydrological reinforcement. In vineyards, the hydrological reinforcement effect could be observed also during autumn, winter and spring periods, giving a contribution to slope stability also in these conditions. This situation occurs when plants uptake enough water from soil to reduce significantly pore water pressure, guaranteeing values of hydrological reinforcement of 1-3 kPa at 1 m from ground, in agreement with measured mechanical root reinforcement (up to 1.6 kPa). These results suggest that both hydrological and mechanical effects of vegetation deserve high regard in susceptibility towards shallow landslides, helping in selection of the best land uses to reduce probability of occurrence of these failures over large territories.

The impacts of climate change and soil erosion are significantly affecting agriculture in non-developed countries. In Mali, a country located in Western Africa, there is a drastic reduction in available fertile arable lands and water scarcity, which is damaging rural communities and affecting the development of vital infrastructures, consequently, decreasing people's incomes. There is a lack of information about the perception of these challenges among the small rural communities and the possible adaptation strategies can be applied. Therefore, the main aim of this study was to determine local farmer perceptions of climate change, soil erosion, and adaptation strategies conducting a survey among 200 farmers in 10 villages within the rural municipality of M & eacute;gu & eacute;tan, serving as a representative study case. Our results showed that farmers are aware of the challenges related to climate change and soil erosion and are willing to adopt some measures but conditioned by a range of traditional techniques. The most common strategies are: changing the sowing calendar, diversifying crops, using resistant varieties, having an alternative income, and following weather forecasts on the radio. Stone rows remain the most widely adopted technique to reduce soil erosion, with a knowledge rate of 88% and an application about 29%. The study also highlighted the increasing vulnerability of farmers to climate change and soil erosion due to insufficient material and financial resources. We conclude policies should pay attention to services and partners that invest more funds in technical assistance to strengthen adaptation strategies and teach the population, considering nature-based solutions.
