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.

Geoportal Hamburg

Das Geoportal Hamburg ist das zentrale Kartenportal der Stadt Hamburg. Es enthält alle verfügbaren Geodaten der Hamburger Verwaltung in der stets aktuellen Version. Die Daten werden hierbei durch die einzelnen Fachbehörden gepflegt und über die Urban Data Platform, der zentralen Datendrehscheibe der Stadt veröffentlicht. Es stehen so mehr als 500 Datensätze verschiedener Kategorien zur Verfügung sowie zahlreiche Werkzeuge zum Suchen, Zeichnen, Messen oder Drucken. Die technische Basis des Geoportals ist die Opensource-Software „Masterportal“ die vom Landesbetreib Geoinformation und Vermessung entwickelt und von zahlreichen anderen Städten und Kommunen genutzt und in Zusammenarbeit gepflegt und weiterentwickelt wird.

Potential of the medicinal plant Passiflora incarnata L. as cover crop in fruit tree plantations in North Thailand

Erosion of the often uncovered soil is a major problem for the establishment of smallholder fruit tree plantations in North Thailand. The use of multi-purpose cover plants can not only conserve useful soil resources but also create further income for peasants. Dried plant material from the passion flower (Passiflora incarnata L.) is used for herbal tea and extracts to be used as sedativa. The species is widespread in the Southern USA. The drug is often produced based on wild collections and exported to Europe. In exploratory trials in Thailand passion flower showed a good drought resistance due to its deep rooting system, and a good resistance against weeds and diseases. The yield potential and the amounts of ingredients appear to be promising with regard for the adoption by farmers. The flavonoids in the passion flower are mostly flavone-C-glycosides and are used for characterisation of the drug. Quantitative studies of imported drug material showed large differences in quantities and types of the flavone-C-glycosides. The causes for these differences are still not understood. Not much is known about the effect of cultivation techniques, fertilizer, growth stage on the content of flavonoids. The objective of this project is to study the potential of the passion flower as a soil cover plant in smallholder fruit tree plantations in North Thailand. Factors to be monitored are the effects of fertilizer and growth stage at harvest on plant yield and components.

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
