Development of a modelling system for prediction and regulation of livestock waste pollution in the humid tropics

Introduction: In Malaysia, excessive nutrients from livestock waste management systems are currently released to the environment. Particularly, large amounts of manure from intensive pig production areas are being excreted daily and are not being fully utilised. Alternatively, the excess manure can be applied as an organic fertiliser source in neighbouring cropping systems on the small landholdings of the pig farms to improve soil fertility so that its nutrients will be available for crop uptake instead of being discharged into water streams. Thus, there is a need for better tools to analyse the present situation, to evaluate and monitor alternative livestock production systems and manure management scenarios, and to support farmers in the proper management of manure and fertiliser application. Such tools are essential to quantify, and assess nutrient fluxes, manure quality and content, manure storage and application rate to the land as well as its environmental effects. Several computer models of animal waste management systems to assist producers and authorities are now available. However, it is felt that more development is needed to adopt such models to the humid tropics and conditions of Malaysia and other developing countries in the region. Objectives: The aim is to develop a novel model to evaluate nutrient emission scenarios and the impact of livestock waste at the landscape or regional level in humid tropics. The study will link and improve existing models to evaluate emission of N to the atmosphere, and leaching of nutrients to groundwater and surface water. The simulation outputs of the models will be integrated with a GIS spatial analysis to model the distribution of nutrient emission, leaching and appropriate manure application on neighbouring crop lands and as an information and decision support tool for the relevant users.

Impact of long-term exposure to elevated pCO2 on activity and populations of free living N2 fixing organisms in a temperate grassland system

The project aims at achieving a better understanding of the processes that drive or limit the response of grassland systems in a world of increasing atmospheric pCO2. We will test the hypothesis that the previously shown increase in below-ground allocation of C under elevated pCO2 provides the necessary energy excess and will stimulate free-living N2 fixers in a low N grassland environment. The project thus aims at assessing the occurrence and importance of free-living N2 fixers under elevated pCO2 and identify the associated microbial communities involved in order to better understand ecosystems response and sustainability of grassland systems. This project had the last opportunity to obtain soil samples from a grassland ecosystem adapted to long-term (10 year) elevated atmospheric pCO2 as the Swiss FACE experiment. The project aims to identify the relevant components of free-living diazotrophs of the microbial community using 15N stable isotope - DNA probing.

Governing the Common Sea (GOVCOM)? Changing modes of governance in the Baltic Sea Region

The pattern of environmental governance is changing as national governments are under stress from new political agents. In addition to the traditional nation state centered policy-making system, including international cooperation, political power is also exercised on the trans-national and local levels of society. A simultaneous movement of political power is also exercised on the trans-national and local levels of government and downward to local communities. Sub national units such as local governments, civic organisations and even loosely constructed networks introduce their own environmental policies. Global sustainability problems are created by the interaction of all societal levels, and a new politics of sustainability involving local, national, regional as well as global efforts must be implemented to solve these problems. National governments have responsed to this situation by introducing programs promoting ecological modernisation as well as new policy instruments that involve communities and other actors. The Baltic Sea Region (BSR) is an area of special concern both from an environmental point-of-view as well as from a governance point-of-view. The sea itself is highly vulnerable to pollution. At the same time the region is an ideal setting for the research because it has introduced several new fora for sustainable decision making, while showing considerable strength in existing administrative and political structures. The main objectives for this project are: Module 1. to deepen understanding of the origins, development and operation of traditional environmental governance in the BSR

Entwicklung eines Simulationsverfahrens zur Minderung von Schmutzfrachtausträgen aus mittleren bis großen Kanalisationsnetzen durch Einsatz moderner Steuerungselemente - Phase II

Das übergeordnete Ziel dieses F&E Projektes war die Minderung der Schmutzfrachtausträge unter Beibehaltung des Entwässerungskomforts. Das Vorhaben sollte der Bedeutung präziserer Abschätzungen von Schmutzfrachtausträgen und Überflutungen im Bereich der Stadtentwässerung Rechnung tragen. Nach langjähriger Pionierarbeit der Antragsteller beim Einsatz von Multiprozessor-Technologien in der hydrodynamischen Kanalnetzberechnung, war es das Ziel, diese in den Dienst eines quantitativen Nachweises der Emissionen aus Misch- und Trennsystemen mittlerer und großer städtischer Einzugsgebiete zu stellen. Dadurch sollte die Einbeziehung zunehmend genauerer, multidimensionaler geographischer und meteorologischer Daten zu diesem Zwecke besser bzw. überhaupt erst möglich werden. Dies sollte nicht nur wegen des zwingenden Einsatzes von entsprechenden Nachweisen aufgrund europäischer DIN-Normen geschehen, sondern vor allem im Rahmen einer notwendigen und sinnvollen Ergänzung praktischer Ingenieurstätigkeit in Zeiten national wie international gestiegener Ansprüche infolge (klimabedingt) gehäufter Extremniederschläge. Um die geforderten Ziele zu erreichen, wurden in den letzten Jahren von den Projektpartnern innovative Komponenten entwickelt, um die Abflüsse in den Kanalnetzen zu steuern und die im Kanal vorhandenen Volumina zu aktivieren und für eine Misch- bzw. Regenwasserbehandlung zu nutzen, ohne die Sicherheiten zu beinträchtigen. Als Ergebnis dieses F&E Projektes kann den Partnern, Genehmigungsbehörden, Hochschulen, Betreibern, planenden und ausführenden Ingenieurbüros ein wirksames, auf Multiprozessortechnologie und auf dem komplexen Parallelschrittverfahren basierendes Instrument (FLOW++) zur präzisen, aber auch einfachen Abschätzung und Beurteilung der hydraulischen und ökologischen Situation im Kanalnetz bzw. im Gewässer zur Verfügung gestellt werden. Das Verfahren eignet sich sowohl zur Bestimmung des IST-Zustands als auch für den Vergleich verschiedener Planungszustände zur Optimierung der hydraulischen und ökologischen Auswirkung geplanter Netzerweiterungen und Optimierung mit den im Verfahren berücksichtigten Steuerkomponenten.

Irkutsk Regional Information System for Environmental Protection (IRIS)

Background: IRIS builds on former Framework Programme 4 and 5 projects, extends their networks to Russia and adopts some of their findings to the specific needs of the involved governmental agency. This implements for the first time that the scientific results from former EC-funded scientific co-operations are being collected and transformed to tools for regional management by the administration. Consequently, the involvement of the potential IRIS user community is the most challenging objective and remains an ongoing process. Impacts: As a result of project implementation the prospective research initiatives for the creation of regional GIS, pollution transport models, industrial development scenarios and risk assessments will be formulated. IRIS will be useful for officials of the Russian Federation at different levels of state hierarchy, i.e. at regional level (Irkutsk Region), inter-regional level (since the neighbouring areas are also included in IRIS as the present/potential sources of pollution) and federal level (e.g. management of federally controlled nature resources and stress on the environment by enterprises held in federal property). The international dimension of project implementation is strongly connected with problems of climate change essential worldwide and, in particular, for EU Member States. There is no doubt today that the role of the boreal forests is essential. In this context the Siberian taiga, which is the largest forest region in the world, and Irkutsk region as a part of taiga is of vital importance. Thus the strategic impact of the project could be felt on both national and international levels, helping to manage the environment and develop effective solutions of regional and global problems facing the society. Objectives: The Irkutsk Regional Information System for Environmental Protection - 'IRIS' assesses the current status and dynamics of the Irkutsk Region's forestry environment, influenced by man-made changes and anthropogenic impact arising from pollution sources and other negative anthropogenic drivers located in the region and in adjacent areas. It will investigate the responsiveness and vulnerability of forestry environment within the region under different scenarios of industrial development and nature-preserving measures. The major goal of IRIS is to efficiently share Earth Observation data and domain-specific (ecologic and economic) information within earth science community and regional governance to identify environmental impacts that are both economic and socially responsible. Thus, for integrated environmental management methodical designs are necessary which refer to the complexity of the natural resource to be managed and the difficulty to predict the factors or driving forces influencing them.
