"Former floodplains in many European countries increasingly suffer from serious floods due to intensified human activity. These floods have caused safety and ecological problems as well as they have resulted in economic losses in agricultural used watersheds. In this context, the influence of the management practice of forest transformation in forested areas on soil hydraulic properties is presented and discussed as a means of preventing such disasters at a reasonable cost and during a foreseeable period."
"It is concluded that for the approximate duration of one century the practice of forest transformation does not contribute to flood... more
The town centre of Lezo is crossed by various watercourses which collect the waters of Mount Jaizkibel and whose associated ecosystems have been reduced due to the effect of anthropisation and urban development pressure. The town council has been working for several years on the regeneration and enhancement of these watercourses, as is the case of Olatzar, the course of which runs alongside the town's urban garden park.
The BUND Naturschutz is in possession of some areas in the Mariensteiner Moors. Since 1981, these areas have been regularly cleared of bushes and a stream that previously drained the area has been closed. Extensification of surrounding areas is planned.
Many pastures in the mountain areas of Azerbaijan are in bad condition. High numbers of livestock and bad management practices lead to a loss of vegetation and subsequent soil erosion. Degraded pastures result in a loss of biodiversity and livelihoods and a rising risk of landslides. Estimated temperature rise and an increase in extreme weather events will accelerate land degradation. Even though a rise of rainfall might be beneficial for pastures, changing land uses and increased evaporation will amplify soil erosion. The government and district administration lack coordination and finance for the sustainable management of public pastures... more
The BUND Naturschutz carries out care measures at an project area of 2000 ha at the moors at the Samerberg. On an area of about 20 ha they are mowing the area.
To improve the ecological situation at the Reitbach, the section below the new flood control reservoir was redisgned close to nature. 5 drop structures were replaced by river bed ramps to improve fish migration.
The BUND Naturschutz restored some areas of the Höfner Filz in 2005. Drainage ditches were closed and interrupted, emerging spruce stands were removed and a terrain level was adjusted to connect the area with an area already restored in 1993.
The goal of this work is to implement and improve protection against floods
Following 1999 floods, the Obere Iller was widened, restored and a new retention area was created.
The originally natural gradient is largely removed by the transverse structures erected as a result of the straightening of the Iller. This created waterways with a low gradient and the pre-alpine watercourse characteristics were lost. Through the construction of side arms, an attempt is being made to extend the river habitats with natural bed layers and a high habitat function. It enables an approximation to the natural, branched course of the watercourse with its numerous side channels.
