Green and blue infrastructure in cities in the light of economics and residents' preferences

How to overcome barriers to the adoption of green and blue infrastructure
using economic assessment


The number of people living in cities has increased rapidly in the last decades due to a rapid
population growth and, most importantly, increasing rates of urbanisation. The ongoing climate
change brings along phenomena that may have an impact primarily on city inhabitants in the future,
for example through water deficiency, (flash) floods, heat waves or drought. It is therefore necessary
that cities react to these new conditions and use adaptive measures to help their inhabitants to
adapt to climate change. We know how to do it, and we're excited to get started! Although Czech
cities are considered relatively green in international comparison, we cannot rely on current
measures. It is necessary to look for other places for greening such as green roofs and facades or blue
infrastructure elements, which are lacking in Czech cities.
The implementation of these measures is associated with a number of barriers (lack of funding and
incentives, priorities directed to other public service areas, conflicts of interest, etc.). Awareness of
both decision-makers and the general public plays an important role in this. The awareness and
therefore the acceptance of the measures can be increased through appropriate communication. The
results of economic assessment in the form of economic arguments play an important role in how to
present green and blue infrastructure in an easily understandable form.
To achieve these objectives, we can combine a number of methods, such as preference survey, cost-
benefit analysis, ecosystem services assessment, etc. The application of these methods in relation to
innovative examples of blue-green infrastructure elements and provided benefits will be the main
focus of the presentation.

Jan is an environmental economist, project coordinator and university teacher at the Faculty
of Social and Economic Studies of the Jan Evangelista Purkyne University in Usti nad Labem.
He is an expert on the economic issues of green and blue infrastructure, climate change
adaptation and water management. He is also involved in popularising the topic to the
general public.

Among other things, he co-authored the publication Water in the City, which brought a
unique comprehensive view of rainwater management to the Czech environment. This
combined a purely technical view of measures with planning, economic, environmental and
landscape aspects.
