As a result of this year’s international conference on water security and climate change at the TH Köln – University of Applied Sciences, 200 researchers from around 45 countries have adopted the ‘Cologne Declaration on Water Security and Climate Change’. They confirm that a concerted collaboration between science, politics, business, and civil society is required at all levels in order to ensure the water supply worldwide and manage the risks of climate change.
“Climate change has a massive influence on how the limited resource drinking water is managed. At the same time, well-designed water management is a key factor in enabling societies to adapt to climate change. Due to this complex system with its many natural and man-made influence factors, we require a comprehensive, interdisciplinary approach,” explains Prof. Dr. Lars Ribbe, head of the Institute for Technology and Resources Management in the Tropics and Subtropics (ITT) at TH Köln.
The Institute and its associated Center for Natural Resources Development (CNRD) organized the conference together with the Food Security Center at University of Hohenheim and the Center for Sustainable Water Management in Developing Countries at Technische Universität Braunschweig. As academic excellence centers for exchange and development all three institutions are supported by the German Federal Ministry for Economic Cooperation and Development.
How diverse but closely linked these major topics of our time are show the core messages on individual aspects which the researchers have formulated, such as on cross-border water management, urbanization, and migration.
“Water availability and migration flows are often mutually dependent,” says Prof. Andreas Haarstrick from TU Braunschweig. “We thus observe in African and Asian countries that extreme weather events such as droughts trigger migration flows within a country, specifically from rural to urban regions. The local infrastructure to provide clean water and treat wastewater cannot keep up with the rapidly growing population. A further result of this migration flow is the excessive and uncontrolled exploitation of surrounding water resources. This leads to poorer water quality due to the drop in groundwater level. Technology to combat these problems on site is already available. Implementation, however, often fails due to corruption and mismanagement in the affected countries or even because sustainable water projects are not a priority for the local government.”
The researchers are demanding that significantly more efforts and resources be invested in projects, organization, and scientific institutions in order to develop research- and fact-based solutions. Universities must be founded and financed, above all in developing countries, in order to generate knowledge in the countries that are most severely affected by climate change and water shortage. Especially at a local and regional level, there is a lack of structures to enable collaboration between a wide range of partners and thus to make sure that strategic goals decided at an international level can also actually be implemented. The researchers see a key role here for universities. “They are anchored locally, they generate knowledge, and their task is to educate and pass on their knowledge” emphasizes Prof. Ribbe.
“The conference is a good example on how we see ourselves as TH Köln. We want to devise innovative solutions together with politics, business, and civil society on the basis of substantiated scientific findings,” highlights Prof. Klaus Becker, Vice President at TH Köln. “With the declaration that has now been adopted, academia is sending a clear signal of its interest in collaborating with partners at various levels.”
