  • Global Issues

    In a globalized world, issues such as climate change, food security, and migration cannot be addressed by individual countries. These are global issues that demand a cross-border approach and an international cooperation. Global issues are the major theme in the research of Kaleidos Research. For further information regarding this theme, please contact Edith van Ewijk or Gabi Spitz.

  • Global Citizenship

    How the Dutch work, consume, think, and how they interact with each other, influences the rest of the world. Kaleidos Research researches how the Dutch (young and old) and their everyday behavior (whether conscious or not) contributes to a better and sustainable living environment, here and there. Furthermore, Kaleidos Research evaluates projects part of the – either formally or informally – global citizenship education. For more information about global citizenship, please contact Christine Carabain or Lette Hogeling.

  • Sustainable Development

    While a large majority of the world population has the means to consume without limits, hundreds of millions of others continue to live in poverty. How do we find a balance between on the one hand, the need to consume and, on the other hand, nature and the environment, considering also the needs of future generations? We try and find out more about the role the government, companies, citizens and other social actors have on sustainable development. Contact Ries Kamphof or Gabi Spitz if you would like more information about sustainable development.

  • International Cooperation

    How do Dutch stakeholders on an international level deal with global issues such as climate change, poverty reduction, financial stability, scarcity of natural resources, energy security, security, and migration? Kaleidos Research analyzes international cooperation and policy issues in relation to these global issues. To find out more about international cooperation, please contact Gabi Spitz or Edith van Ewijk.


  • Evaluation Research

    For (international) customers, Kaleidos Research evaluates the impact and effectiveness of their interventions. Experts at the Kaleidos Research use baseline and follow-up measurements, including complex statistical analysis on large-scale data files, to conduct ‘evidence based’ qualitative evaluations. In addition, qualitative and participative methods such as the Most Significant Change method, interviews, or focus groups, give a greater insight into the processes. Contact Marije van Gent or Lette Hogeling for more information about evaluation research.

  • Policy Research

    Kaleidos Research researches Dutch and international policy with respect to sustainable development, and compares policy solutions with the opinions of the Dutch people. By combining different methods, the policy research contributes to making, evaluating, and adjusting the policy. Please contact Gabi Spitz or Ries Kamphof if you would like more information about policy research.

  • Opinion Research

    Kaleidos Research researches the thoughts, knowledge, and behavior of the Dutch in relation to global issues and international cooperation. This information is an indication of, among other things, public support for the policies. Our opinion research is not limited to these descriptive statistics. We believe the why is just as important: why do the Dutch act this way? And how can we stimulate sustainable behavior? Hence, not only describing, but also explaining! For more information about the opinion poll, please contact Evelien Boonstoppel or Christine Carabain.

  • Accessible Research

    Via oneworld.nl/research, Kaleidos Research makes (scientific) research accessible for a wider audience. In cooperation with the national media, research conducted by Kaleidos Research is brought to attention. Moreover, the research results are visualized with the use of animation films and infographics. We also stimulate the discussion among professionals by organizing expert meetings. Would you like to know more about how to make your own research more accessible, or what we can mean for you? Edith van Ewijk or Christine Carabain will gladly help you.
