Human civilisation and its society on our planet is undergoing major transitions. The global population is still increasing, although there are regions were the increase is not only slowing down, but even a decrease is in sight. All over the globe people are moving to cities. In Asia huge megacities with over 10 million inhabitants are already no exception. Together these developments lead to an unprecedented growth in food demand and thus production in and near the urban areas. Paradoxical most urban areas were and still are created on the fertile land in the river deltas all over the world.
Not only the growing food demand pressures the food production, also its housing needs and infrastructure have a negative impact on het area available for food production. Urbanization also creates a great number of challenges to secure a healthy living environment in the metropoles. These interdependent challenges constitute the subject of the second issue of this book: to ensure food security in tomorrow’s cities. How and where will it be produced, stored, processed and transported, without great losses in both quantity and quality? Fortunately science and technology are advancing rapidly. We already have ways, methods and systems to ensure healthy food security in the near and further future. But we must develop new and more sustainable agricultural practices and implement them in our societies.
Continuous availability of high-quality water is essential for food production. Yet, freshwater availability is under increasing pressure worldwide. Securing fresh water for drinking water, industries, and agriculture requires innovative thinking in water resource management and use of nature-based solutions. Allied Waters-SALutions is dedicated to implementing these solutions to help to meet water demands.
Allied Waters – SALutions capitalizes upon 65 years of water storage and treatment experience that has successfully secured water supply in urban coastal regions in The Netherlands, adding new features to secure water availability in various environments and at various scales.
