soil erosion is a main hazard in most area of the country specially in arid and semi-arid regions and itis very important because of sedimentation, pollution, increased flooding and its negative effects onsoil productivity. one of the features of arid and semi-arid areas is the presence of low cover ofvascular plants. these empty spaces are usually good niches for biological soil crusts or cryp...

Vertical-flow constructed wetlands (VFCWs) are an innovative and sustainable nature-based technology for wastewater treatment in rural areas. This work aimed to evaluate the performance of VFCWs using real wastewater, which can provide more accurate reliable results compared with field-based experiments, investigate use Paulownia trees treatment. To compare efficiency plants based on VFCWs, thr...

Abstract Groundwater is one of the most important water sources in arid and semi-arid areas. With increasing world population demand for agriculture urban use, need resources has increased, especially regions, where groundwater play a significant role. To prevent pollution resources, various studies their preservation maintenance should be carried out, including detailed plan proper management ...

The semi-arid regions of northeastern Brazil have historically suffered from water shortage. In this context, monitoring and modeling the soil moisture’s dynamics with hydrological models in natural (Caatinga) degraded (Pasture) is fundamental importance to understand processes. Therefore, work aims evaluate hydraulic parameters Caatinga Pasture areas using Hydrus-1D inverse method. Thus, five ...

Climate change is having a tremendous influence on world food production, with arid, semi-arid, and dry sub-humid areas especially susceptible. In these areas, locally adapted crop varieties or landraces can be used to mitigate the of climate current future security challenges. The high genetic diversity within populations allows for crops adapt changing environments other stresses that growth ...
