Combining land use and water management objectives is the key to sustainable development

Water – its Control and Combination: Multifunctionality and Flood Defences, by Monica Altamirano, Rik Jonker, and Jurgen van der Heijden, Osborne/Deltares, June 2013 (Google the title for free download of the recent English version)

A road on a dyke with sheep on the slope beside it. Can this age-old combination inspire the development of modern flood defenses? Think of dykes producing renewable energy, or serving as nurseries for new plantlife. A good reason to make combinations like these is their sustainability. Three Dutch experts present and analyse a collection of almost thirty examples, mostly from the Netherlands. Although meant as a factual report, this book puts forward a message deserving extra thought.

An area is set aside for water storage to prevent flooding of a nearby city. This area is also a place for nature conservation, water treatment, open city and recreation. Developing and using the same land for multiple purposes saves space, time and money. Yet, however interesting, this isn’t what makes these combination special.

Authorities are used to optimizing each function separately; for instance, creating a basin for water storage as wide and deep as possible at the lowest possible cost. Combining functions sharing can bring the cost down, but what is special is how multiple functionalities can optimize one another. Water storage helps nature, and nature helps water treatment. Such combinations enhance spatial quality, resulting in a better place for recreation. Revenues from recreation can be devoted to nature conservation.

Using one function to optimize others provides a unique economic force that has always been there, but has yet to be fully explored. The authors prove with almost thirty examples that such an approach contributes to sustainable development. This is an inspiring book for water managers who want to go beyond traditional solutions.
