“…Water erosive processes cause soil degradation through the breakdown, transport, and deposition of particles by the action of water from raindrops and runoff, which corresponds with ~72% of the land affected by soil erosion in the world [1]. Its occurrence is intensifying due to climate change and human actions; therefore, it is one of the main environmental and socioeconomic challenges that society faces today.…”

Conservation units are strategic territories that have a high demand for public use, as they protect attractions of great scenic beauty, geodiversity sites, and numerous leisure areas. However, when carried out in an intensive and disorderly manner, tourist activity in these areas tends to catalyze environmental degradation, triggering, for example, water erosion processes caused by intensive soil trampling on the trails. In this sense, the aim of this study was to determine the soil’s physicochemical characteristics, and to spatiotemporally monitor the microtopography of those areas degraded by erosion along two trails on Serra da Bocaina National Park coast of the Paraty Municipality. The findings verified that intensive trampling, the values of some soil physicochemical characteristics, and the specific meteorological conditions of the coastal region of this protected area were factors that contributed significantly to the evolution of erosion features monitored on these trails. Finally, strategies for appropriate management and recovery actions for these degraded areas are proposed in order to not only stop the erosive processes and re-establish the local ecosystem balance, but also avoid accidents involving the numerous tourists who visit the coastal region.

Desta maneira, o rompimento dos agregados do solo e o respectivo destacamento de suas partículas pela erosão por splash devido à ação da água meteórica, faz com que haja o selamento da camada superficial do solo através da formação de crostas em seu topo, o fechamento de seus poros, a redução da infiltração da água em seu interior e o aumento do volume de água escoada em superfície, ou seja, processos que favorecem a ocorrência e a evolução dos processos erosivos como as que foram monitoradas nas trilhas do PNSB (GUERRA et al, 2017; FERNÁNDEZ-RAGA et al, 2017; RANGEL et al, 2019; FIGUEIREDO; MARTINS, 2021; CENTERI, 2022).…”

A erosão hídrica superficial é um dos processos responsáveis pela degradação dos solos, especialmente em áreas tropicais, devido aos elevados índices pluviométricos. A análise da microtopografia do solo é um dos métodos de mensurar a evolução e desenvolvimento deste processo, principalmente em áreas sob uso intensivo, como trilhas em unidades de conservação. O litoral do Parque Nacional da Serra da Bocaina, no estado do Rio de Janeiro, apresenta diversos pontos de interesse geoturístico, que atraem inúmeros visitantes diariamente, desencadeando vários impactos ambientais nas trilhas que dão acesso a estes atrativos. Sendo assim, esta pesquisa teve como objetivo avaliar a evolução espaço-temporal dos processos erosivos no leito de duas trilhas deste parque, através do monitoramento da microtopografia do solo em dois períodos distintos. Posteriormente, os resultados foram correlacionados com os dados das precipitações pluviométricos e com as características fisiográficas da área. Constatou-se que ambos os pontos monitorados estão sofrendo com a perda de solo devido, principalmente, aos elevados índices pluviométricos, que se concentram nos meses de dezembro e janeiro. A visitação intensa e desordenada, a cobertura vegetal e quantidade de serrapilheira foram fatores que possivelmente influenciaram a evolução destes processos no leito das trilhas, gerando dinâmicas distintas entre os pontos monitorados.

The cover management factor is one of the main five factors that is used within the universal soil loss equation to reflect the effect of cropping and management practices on soil erosion rates. It is determined through tables and equations derived in tropical and European conditions, which are not suitable for semi-arid regions with different climate, topography, and soil characteristics. Therefore, this study considers al-Arish basin in Sinai Peninsula, Egypt as a semi-arid study area to generate a cover management factor’s equation in terms of the Normalized Difference Vegetation Index using hydrological modeling and satellite images processing. To verify the proposed equation, it was applied to the Derna catchment in Libya and compared with European and tropical ones with respect to the hydrological outputs. Statistical analysis indicates that the proposed equation determines the cover management factor more accurately than those developed for tropical or European regions, as the correlation coefficient between the cover management factor and the hydrological results was 0.71, while it was about 0.20 for the European and tropical, equations, also the degree of agreement between the proposed equation’s results and the hydrological simulation was 0.768 while it was 0.001 and 0.02 for the tropical and European equations respectively. By utilizing the newly developed equation, the soil erosion can be estimated more accurately for the semi-arid regions, and a better understanding of the relation between the vegetation cover and soil erosion can be drawn.
