B 5.1: Fate of agrochemicals in integrated farming systems in Son-La province, Northern Vietnam

Das Projekt "B 5.1: Fate of agrochemicals in integrated farming systems in Son-La province, Northern Vietnam" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Bodenkunde und Standortslehre, Fachgebiet Biogeophysik durchgeführt. In Son La province, Northern Vietnam, many irrigated farming systems include ponds in which small-scale farmers raise fish to produce additional food and income. The main field crops in this area are paddy rice and maize. Often, irrigation water is first used in paddy fields, before it flows to the fishponds. Because farmers regularly apply considerable amounts of agrochemicals, mainly insecticides, to field crops fish production suffers. Moreover, agrochemicals may enter the human food chain. Subproject B5.1 will study the fate of agrochemicals applied in two subcatchments near Yen Chau, Son La province. Investigations will be carried out in close collaboration with A1.3, B4.1, C4.1, D5.2, and G1.2. In the two subcatchments, fishponds have been investigated by D5.1 since 2003. We will carry out a survey of the subcatchments with special emphasis on the water distribution systems (fields, ponds, canals, brooks). The data will be linked to the GIS (Geographical Information System) set up by B4.1. In one subcatchment, B5.1 will install a weather station as well as five TDR (time do-main reflectometry) probes and tensiometers. Water flow through the system will be recorded by means of water meters and V-shaped (Thompson) weirs equipped with automatic pressure sensors. Soil and water samples from selected fields sites, pond inflows, and ponds will be regularly screened for agrochemicals using the procedure developed by B2.1 (Ciglasch et al., 2005; see below). Soil and sediment characteristics that determine water regime and soil-agrochemical interaction, e.g. texture, organic carbon content, hydraulic conductivity, partitioning coefficients, and half-life times will be measured in laboratory and field experiments in cooperation with B4.1. In preparation for the next phase, discharge will be assessed and agrochemical concentrations monitored in the main catchment.

Grey water treatment in upflow anaerobic sludge blanket (UASB) reactor

Das Projekt "Grey water treatment in upflow anaerobic sludge blanket (UASB) reactor" wird vom Umweltbundesamt gefördert und von Technische Universität Hamburg-Harburg, Institut für Abwasserwirtschaft und Gewässerschutz B-2 durchgeführt. In ecological sanitation, the wastewater is considered not only as a pollutant, but also as a resource for fertiliser, water and energy and for closing water and nutrients cycles (Otterpohl et. al., 1999; Otterpohl et. al., 2003; Elmitwalli et al. 2005). The ecological sanitation based on separation between grey and black water (and even between faeces and urine), is considered a visible future solution for wastewater collection and treatment. Grey water, which symbolises the wastewater generated in the household excluding toilet wastewater (black water), represents the major volume of the domestic wastewater (60- 75 percent) with low content of nutrients and pathogens (Otterpohl et. al., 1999; Jefferson et al., 1999; Eriksson et al., 2002). Most of grey-water treatment plants include one or two-step septic-tank for pre-treatment (Otterpohl et al., 2003). The grey-water treatment needs both physical and biological processes for removal of particles, dissolved organic-matters and pathogens (Jefferson et al., 1999). Recently, many researchers have studied the grey-water treatment either by application of high-rate aerobic systems, like rotating biological contactor (Nolde, 1999), fluidised bed (Nolde, 1999), aerobic filter (Jefferson et al., 2000), membrane bioreactor (Jefferson et al., 2000), or by application of low-rate systems, like slow sand filter (Jefferson et al., 1999), vertical flow wetlands (Otterpohl et. al., 2003). Although high-rate anaerobic systems, which are low-cost systems, have both physical and biological removal, no research has been done until now on grey water in these systems. The grey water contains a significant amount (41 percent) of chemical oxygen demand (COD) in the domestic wastewater (Otterpohl et al., 2003) and this amount can be removed by the highrate anaerobic systems. Although high-rate anaerobic systems have been successfully operated in tropical regions for domestic wastewater treatment, the process up till now is not applied in lowtemperature regions. The COD removal is limited for domestic wastewater treatment in high-rate anaerobic systems at low temperatures and, therefore, a long HRT is needed for providing sufficient hydrolysis of particulate organic (Zeeman and Lettinga, 1999; Elmitwalli et al. 2002). The grey water has a relatively higher temperature (18-38 degree C), as compared to the domestic wastewater (Eriksson et al. 2002), because the grey water originates from hot water sources, like shower (29 degree C), kitchen (27-38 degree C) and laundry (28-32 degree C). Therefore, high-rate anaerobic systems might run efficiently for on-site grey water treatment, even in low-temperature regions. The upflow anaerobic sludge blanket (UASB) reactor is the most applied system for anaerobic domestic waster treatment. Accordingly, the aim of this research is to study the feasibility of application of UASB reactor for the treatment of grey water at low and controlled (30 degree C) temperatures.

Forest management in the Earth system

Das Projekt "Forest management in the Earth system" wird vom Umweltbundesamt gefördert und von Max-Planck-Institut für Meteorologie durchgeführt. The majority of the worlds forests has undergone some form of management, such as clear-cut or thinning. This management has direct relevance for global climate: Studies estimate that forest management emissions add a third to those from deforestation, while enhanced productivity in managed forests increases the capacity of the terrestrial biosphere to act as a sink for carbon dioxide emissions. However, uncertainties in the assessment of these fluxes are large. Moreover, forests influence climate also by altering the energy and water balance of the land surface. In many regions of historical deforestation, such biogeophysical effects have substantially counteracted warming due to carbon dioxide emissions. However, the effect of management on biogeophysical effects is largely unknown beyond local case studies. While the effects of climate on forest productivity is well established in forestry models, the effects of forest management on climate is less understood. Closing this feedback cycle is crucial to understand the driving forces behind past climate changes to be able to predict future climate responses and thus the required effort to adapt to it or avert it. To investigate the role of forest management in the climate system I propose to integrate a forest management module into a comprehensive Earth system model. The resulting model will be able to simultaneously address both directions of the interactions between climate and the managed land surface. My proposed work includes model development and implementation for key forest management processes, determining the growth and stock of living biomass, soil carbon cycle, and biophysical land surface properties. With this unique tool I will be able to improve estimates of terrestrial carbon source and sink terms and to assess the susceptibility of past and future climate to combined carbon cycle and biophysical effects of forest management. Furthermore, representing feedbacks between forest management and climate in a global climate model could advance efforts to combat climate change. Changes in forest management are inevitable to adapt to future climate change. In this process, is it possible to identify win-win strategies for which local management changes do not only help adaptation, but at the same time mitigate global warming by presenting favorable effects on climate? The proposed work opens a range of long-term research paths, with the aim of strengthening the climate perspective in the economic considerations of forest management and helping to improve local decisionmaking with respect to adaptation and mitigation.

Demonstration of a sustainable CHP concept using residues from olive oil production (OLIVEPOWER)

Das Projekt "Demonstration of a sustainable CHP concept using residues from olive oil production (OLIVEPOWER)" wird vom Umweltbundesamt gefördert und von New Energy Biomasse Hellas GmbH durchgeführt. Objective: The project focuses on the demonstration of an innovative and sustainable CHP concept using residues from olive oil production (olive wastes) as fuel. A first plant based on the new concept will be realised in Greece. The main objective of the project is to demonstrate a closed cycle concept able to reduce landfill problems and emissions and to promote the use of renewable electricity production in Southern Europe. The project will be based on an approach integrating the whole chain (fuel logistics and preparation, energy production, by-product utilisation). An optimised fuel logistic concept will guarantee for a secured fuel supply over the whole year. The fuel will not only be dewatered and dried but also a marketable by-product will be produced. By this means a better fuel quality can be achieved and solid wastes as well as waste- water can be omitted. The development and design of the combustion unit focuses on a technology tailored to the special characteristics of the olive waste.

Soil N dynamics as affected by different land use in Western and Southern China

Das Projekt "Soil N dynamics as affected by different land use in Western and Southern China" wird vom Umweltbundesamt gefördert und von Technische Universität Dresden, Institut für Bodenkunde und Standortslehre durchgeführt. The aim of the research project is to quantify the stocks and turnover of soil nitrogen in Western and Southern China as dependent from soil structure and land use. Key soil characteristics are determined at representative sites with regional specific land use and degradation status. The investigations will follow a land use gradient of natural forests, arable and pasture soils, the latter ones considering different degradation and rehabilitation status. The actual and potential soil nitrogen turnover will be horizon-wise quantified and related to soil structure and land use impacts. Beside mineral nitrogen, also preliminary organic N compounds using physical and chemical extraction will be detected. Parameters for the investigations are, beside total C and N stocks and distribution, gross and net N mineralization, nitrification, microbial biomass C and N and microbial respiration and indicators for soil N turnover like active N pools and light fraction of organic matter. In the last phase the structure of the soil microbial microbial community will be determined and related to indicators of nitrogen status and efficiency. The research activities will be carried out in close co-operation with the Institute for Soil and Water Conservation/ Yangling University at loess soils and the Nanjing Institute for Soil Science/ Chinese Academy for Science in Nanjing at red soil sites.

SP 1.4 Evaluation of nutrient and pollutant cycles of livestock production systems and manure management systems in the North China Plain

Das Projekt "SP 1.4 Evaluation of nutrient and pollutant cycles of livestock production systems and manure management systems in the North China Plain" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Agrartechnik, Fachgebiet Verfahrenstechnik der Tierhaltungssysteme (440b) durchgeführt. The increasing specialization and intensification of the agricultural food production in the North China Plain is leading to restrictions in nutrients and production cycles at farm and regional levels. As a result, livestock production in the North China Plain is entailing serious environmental negative impacts related to manure surpluses and recycling of nutrients, mainly leading to problems associated with water, soil and air pollution. On the other side higher nutrient demands in the local crops is leading to the purchase of chemical or mineral fertilizers when local or on-farm nutrients are not available. Therefore, the efficient use of organic fertilizers not only depends on their availability in the farms, but also on their nutritional composition. Likewise, soil nutrient requirements and plant physiological needs have to be taken into consideration. Indeed, the closer the nutrient cycles and the lower the environmental negative impacts and farm losses are, the greater the chances for a more sustainable resource use in the North China Plain. In the context of the IRTG, aspects of livestock farming in production systems in terms of widely closed nutrients cycles will be integrated. The material flows in different animal husbandry systems will be analysed and the environmental impacts dependent on livestock farming techniques, farms operability and their respective management will be investigated. The applicability and effectiveness of the technical and organizational measures for the reduction of material losses and, the environmental burdens caused by livestock and manure mismanagement in the North China Plain will be reviewed. The benefits and profits for the local cropping systems as result of the application of organic fertilizers originated from livestock farming will be both, ecologically and economically, evaluated as an alternative to replace the use of mineral fertilizers.
