Water for the dry season – Handing over the floodwater harvesting plant in Iipopo, Namibia

14.04.2015

During the rainy season normally there is abundant rain- and surface water sufficient for irrigation purposes available in northern Namibia. During average rainy seasons, the widely branched river arms in the Cuvelai-Etosha Basin, the Oshanas, carry large quantities of water which evaporate during the dry season. With its floodwater harvesting pilot plant in Iipopo the German-Namibian project team from CuveWaters together with the local community has developed a solution for agricultural irrigation during the dry season. Today, the floodwater harvesting plant in lipopo was officially handed over to the village community.

Under the lead of the ISOE – Institute for Social-Ecological Research the project team had been exploring the novel utilization concept of floodwater harvesting.

The floodwater harvesting plant was developed by the Technische Universität Darmstadt. The plant collects floodwater from the local Oshana. During the rainy season it is pumped into underground reservoirs and can then be pumped into smaller raised tanks.

During the dry season ten families are using this water to cultivate vegetables. They use it to irrigate patches within the greenhouse and a vegetable garden by applying water saving drip irrigation. The families till a field each for self-supply.

They also sell vegetables on the market. “In former times we just let the water flow along the Oshanas” as Rauna Nakahambo, farmer and manager of the greenhouse remembers. “But now we got to know this method how to harvest water.” All farmers were trained in agriculture and in efficient water use.

In order to be able to use the plants when – like presently – rain fails to appear, they connected themselves to the public water supply system. “But we know from our time series analyses, that usually there is enough rain to secure the harvests for the next dry season in lipopo”, said project leader Thomas Kluge from ISOE on Monday on the occasion of the inauguration.

Successful Example for German-Namibian Cooperation

“The fact that we succeeded in establishing this measure adapted to the local circumstances is an excellent result of the close cooperation with the local population”, said Kluge and pointed out that the success of this project exemplarily demonstrated how natural water resources could be sustainably tapped with the help of small-scale plants in other dry regions of this planet as well.

The floodwater harvesting plant is part of the CuveWaters overall project in the course of which pilot plants were developed with the help of various technologies in order to utilize local water resources and relive the central water supply system.

The handing over of the floodwater harvesting plant was part of the German weeks which have been taking place since March and which are organized by the German Embassy on the occasion of 25 years of German-Namibian cooperation. The German Ambassador to Namibia, Onno Hückmann also participated in the ceremony.

He described the German-Namibian cooperation within the research project as future-orientated. “CuveWaters is a successful example showing how a research project can be of specific use allowing a long-term perspective for the rural communities”, said Hückmann.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
