INFU Researches into Reutilization of Waste Water in Agriculture

25.01.2007
The Food and Agricultural Organization (FAO) of the United Nations has just awarded the Institute of Environmental Research (INFU) at Universität Dortmund the research assignment concerning the question of reusing poor quality water in agriculture.

Two case studies are included, one in the area of Barcelona, Spain and one in the district Alfajayucan, north of Mexico City. The aim of the research project is to verify the hydrological, ecological and economic advantages of a better use of natural waters in the regions suffering from water shortage.

The reuse of urban waste water can only help to relieve waters and to prevent an excessive use of groundwater when taking the hygienic conditions (like the WHO limits) into account. Above that the irrigation of agricultural areas with poor quality water can ease the water problems prevailing in many regions of the world. And as the use of poor quality water in agriculture saves high quality water (e.g. ground water) for the urban population (“intersectoral water transfer”), it can even improve the drinking water supply.

It is essential to point out that the reuse of urban waste water for agriculture is advantageous as it prevents the loss of earnings and it renders costly or rather ecologically controversial irrigation systems like, for example, expensive advection of water over great distances, construction of dams, etc. unnecessary. Furthermore it has to be verified that the water exchange between agriculture and cities – processed waste water for high quality drinking water – is profitable for both sides. The cities have a secure basis for their drinking water supply and avoid the high costs of water purification, -tapping and -advection. Then again the cost savings enable them to effect equalization payments for the farmers.

Dr. Ingo Heinz from INFU is in charge of the research project which the Agencia Catalana de l’Aigua in Barcelona as well as Dr. Collado, director of Hidropolis Consultants in Mexico City and Dr. Pimentel, president of the Mexican National Committee of the International Commission on Irrigation and Drainage (ICID) take part in.

The research report will be published as a FAO Water Report under the title “Economic Framework of Reuse of Poor Quality Waters in Agriculture” and distributed to all relevant authorities in the UN member countries in 2008.

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
