In Poland, EIA and SEA have been integrated into the planning system in a different way compared to Germany. There, EIA is performed within an independent procedure. For projects mandatorily requiring EIA, the respective county decides on the outcome of an EIA, whereas for projects with case-by-case screening the regional authority's council is responsible for this task. There are still significant uncertainties in the application of SEA which sometimes leads to conflicts with the EU provisions. In Poland, provisions for SEA were already made in the year 2000. Different SEA procedures are established for regional plans and for other environmental plans. Furthermore, in April 2004, provisions for the EA according to the Habitats Directive were made in the Polish nature protection act. EA according to the Habitats Directive is strongly linked to EIA and SEA. Poland is already experienced in the practice of EIA and SEA. However, there still is a lack of methodological guidelines. Furthermore, the different legal provisions and procedures need to be further adjusted to each other.
Monitoring of groundwater and surface water levels in the Middle Havel area - a basis for the management of landscape water resources The lowland of the middle stretch of the River Havel ("Mittlere Havel", Brandenburg, Germany) is characterised by hydrological conditions that are deeply influenced by draining for agricultural land use. In this area strategies for the sustainable management of landscape water resources are tested in a development and testing project, funded by the German Federal Agency for Nature Conservation. For monitoring of environmental change, the scientifical accompaniment of the project established a network of gauges, measuring ground water levels, water levels in ditches and in the River Havel itself. Data is gathered in areas that are potentially endangered by flood and areas that are protected by embankments. Until now, data from this network is available for more than two hydrological years since autumn 2001. It shows that water level dynamics are mainly influenced by precipitation and evaporation. Only in areas, which are under the potential influence of floods, ground water levels reach water levels in the river during winter term. In areas that are protected by embankments and additionally drained, surface and ground water levels are actually lower than water levels in the river. In addition, ground water levels are influenced by lowering the water levels in ditches. A sustainable landscape water management therefore has to be realised primarily through an altered management of water scoops in the diked areas. This requires the detailed analysis of all relevant hydrological and meteorological data including data about the water scoops.
Spätholozäne Landschaftsentwicklung in Westchina : zwei Fallbeispiele aus der Provinz Qinghai
(2004)
Zusammenfassung Neuere archäologische Forschungsergebnisse belegen, dass seit der frühen Bronzezeit ein intensiver kultureller und wirtschaftlicher Austausch zwischen West- und Südostchina bestand. Es war anzunehmen, dass die Grundlage dieses Austausches vergleichsweise weit entwickelte Landnutzungsaktivitäten waren. Geoarchäologische Untersuchungen über die Umweltauswirkungen der bronzezeitlichen Landnutzung in Westchina fehlen bisher. An zwei Fallbeispielen in der Provinz Qinghai, den archäologischen Fundplätzen Lajia und Fengtai, wird aufgezeigt, dass dort die wirtschaftliche Wertschöpfung auf vergleichsweise intensiver Landnutzung basierte. Die damit verbundene Zerstörung der natürlichen Vegetation ermöglichte katastrophale Erosionsereignisse, die zum Niedergang beider Siedlungen führten. Abstract Late Holocene Landscape Development in Western China ; Two Case Studies from Qinghai Province Recent archaeological research results show that an intensive cultural as well as economic exchange took place between Western and South-Eastern China since early Bronze Age. It can be assumed, that the exchange based on comparatively well developed land use activities. Geo-archaeological investigations concerning the environmental impact of Bronze Time land use in Western China are missing so far. Two case studies about the archaeological sites Lajia and Fengtai located in Qinghai Province show, that the creation of economic value based on comparatively intensive land use. The associated clearing of natural vegetation caused disastrous erosion events, which led to the decline of both settlements.

Die ländlich peripheren Räume Ostdeutschlands gelten vielfach pauschal als schwer zu behandelnder regionaler "Sanierungsfall", dem aber im Vergleich zu den gravierenden Problemen von Bevölkerungsrückgang und Wohnungsleerstand in den Städten weniger Aufmerksamkeit gewidmet werden kann. Fragen nach Umfang und Beweggründen für die Zuwanderung älterer Menschen in diese Räume werden in diesem Zusammenhang ebenso als marginal betrachtet. Trotz der generellen Debatte zum demographischen Wandel wird vielfach noch nicht anerkannt, dass der Ruhestand keine "Restzeit" mehr ist, sondern ein eigener Lebensabschnitt von erheblicher Dauer für einen größer werdenden Teil der Bevölkerung, bei dem die Älteren sehr aktive Phasen durchleben. Der Beitrag stellt Ergebnisse einer Befragung von älteren Zugewanderten in den peripheren Regionen Brandenburgs vor. Auf dieser Grundlage werden Überlegungen zum "Potenzial" dieser älteren Menschen in Bezug auf die regionale Entwicklung und zu Konsequenzen für die räumliche Planung dargestellt.
