For as long as humans began to settle, coastal areas proved attractive
sites for socio-economic processes. In the Netherlands, intensifying
economic processes such as urbanization and globalization
have raised and continue to raise pressure on land use in
those areas. Add to that natural floods and the increasing threat
climate-change-induced sea level rise poses, and a situation of
complex societal interactions emerges, embodied by the term of
“coastal squeeze” (Chapter 1). As demands on land use rose, the
requirements for coastal management also changed: ecological,
recreational and economic opportunities became more prominent
in design processes for coastal safety projects (Chapter 2). One
attempt to combine those spatial functions with coastal safety is the
mega-nourishment scheme – a large amount of sand (>5 million
m³, or 2000 Olympic swimming pools) deposited on and in front of
the beach to increase the coastal protection level in the long term.
Coastal management experts see the mega-nourishment scheme as
an innovative technology, because before Dutch coastal managers
used smaller nourishment amounts of sand to protect coasts for a
few years only. However, the mega-nourishment scheme came a long
way to be accepted as an option in the Dutch coastal management
repertoire. While first ideas already date back to the 1980s, it was
not until 2011 that a broad actor coalition led by a Dutch provincial
government succeeded in implementing the first mega-nourishment
scheme. But this was not without resistance. A period of raising
awareness about the innovative idea and facing opposition on
the part of the advocates of mega-nourishment schemes preceded
its construction in 2011. At the same time, a scientific discourse
advocating experimentation with mega-nourishment schemes
developed. Many experts expected the advantages of mega-nourishment
schemes to outweigh the disadvantages (Chapter 3).
A problem setting including such a complex policy domain led
to a focus on interactions between policy-relevant actors and their
exchange of arguments pro and con the acceptance of mega-nourishment
schemes. Policy situations with such a diversity of interests
and of policy options run the risk of getting bogged down in
discussions about controversial policy problems and solutions.
This holds especially, if the policy debate involves an innovative,
unknown, and untested policy option, such as the mega-nourishment scheme. Definitions of a given problem, scopes of possible and
acceptable solutions to a previously-defined problem and perceptions
of the landscape of policy-relevant actors fall within the realm
of meaning-making. Meaning-making, simply defined, comprises
all mental processes necessary to understand ourselves, our position
in and our relationship with our surroundings. Taking such a
meaning-oriented perspective, this dissertation focuses on the role
of actors’ frames and interactions between those frames in effectuating
policy choice (Chapter 4). Frames can be seen as mental
structures enabling people to bring order into their surroundings
and make sense of them. At the same time, these structures limit
the possibility for people to “see things differently”. This is only one
way of understanding how individuals make meaning.
Taking a meaning-oriented research perspective also has consequences
for the ways in which we can know things about our
research subjects (Chapter 5). A meaning orientation entails understanding
patterns of meaning-making, instead of explaining causal
relations between independent and dependent variables. Hence,
this way-of-knowing (“epistemology”) often links to a way-of-being
(“ontology”), which assumes the existence of multiple social realities
among people involved. People can see things differently, but,
in principle, none of those perspectives is normatively privileged,
i.e. no perspective is truer than another.
A dual objective guides the work in front of you (Chapter 1).
First, the research explored which frames were successful in the
adoption of mega-nourishment schemes in the Netherlands. This
objective traces the political arguments that convinced a majority
of the policy-relevant actors. Second, the research aimed at revealing
those processes of meaning-making relevant for mega-nourishment
schemes to come about. While the findings relating to this
second objective may be relevant for strategic area management 1
as well, its focus is on positioning meaning-making processes in
coastal management in its scientific, conceptual context.
Two overarching research questions follow from these two
research objectives:
A. Which interpretations of the policy situation were
relevant for adding mega-nourishment schemes to the
accepted set of coastal management technologies in
the Dutch coastal management context?
B. How does meaning-making of the policy situation
influence decision-making processes about meganourishment
schemes in the Dutchcoastal
management context?
I studied three cases to answer these research questions, two of
which were mega-nourishment schemes – the Sand Motor and the
Hondsbossche Duinen project – and the third was a small-scale
experiment with sand in the Dutch Markermeer: the Houtribdijk
pilot project (Chapter 5). In all three cases, I conducted qualitative,
in-depth interviews with policy-relevant actors, i.e. employees
of governmental organizations directly involved in the decision-
making processes for the projects. Afterwards, I analyzed
the interviews by focusing on how the interviewees framed various
aspects of the coming about of the projects and how they perceived
the development of debates among actors in retrospect. In
the absence of observed interaction data, the interviews resulted
in indirect data for actors’ framing interactions. “Framing”
describes the different processes with which people communicate
purposefully or sub-consciously with others about a matter
at hand. This way of communicating is always permeated with
the meaning made through a frame. During the reconstruction
of the projects’ frame developments and framing interactions,
eventually the most relevant meaning-making process for every
particular project emerged.
The first empirical elaboration is the Hondsbossche Duinen
project at the North Sea coast in the province of North Holland
(Chapter 6). It involved approximately 30 million m³ sand being
deposited, amounting to a volume of 12.000 Olympic swimming
pools and a surface of 400 football fields. The design included
vegetation and a dune valley for fortification and the creation
of recreational facilities. Throughout this project, actors’ frames
converged more and more. But two changes in project management
were necessary for this. The first change was from the
provincial government of North Holland to the water board
“Hoogheemraadschap Hollands Noorderkwartier”. This happened,
because some actors emphasized the differences between
their own and others’ frames, instead of building on existing similarities.
During the second change, the public works agency came
on board in a combined project management with the water board. This cooperation, unusual for Dutch coastal management, led to
success, because it focused on the similarities between frames.
I devote a second empirical elaboration to the small-scale
Houtribdijk pilot project at the coast of the inland waters of the
Dutch Markermeer (Chapter 7). This project involved experimentation
with the effect of vegetation on nourished sand bodies in inland
waters. For this, the Houtribdijk between Lelystad, Flevoland, and
Enkhuizen, North Holland was nourished with 130.000 m³ of sand.
This amount compares to a volume of 52 Olympic swimming pools
and a surface of 10 football fields. The Houtribdijk pilot is an example
of what can happen in terms of frames and framing if a private
party initiates the project. In this specific instance, the frames
of the few involved actors did not so much aim for cooperation,
but for an efficient realization of the project according to formal
procedures. This low involvement of actors with each other kept
exchange among frames to a minimum.
The Sand Motor project is the third empirical case discussed
in this dissertation (Chapter 8). Constructed in 2011, this was the
first mega-nourishment scheme at the Dutch North Sea coast with
approximately 21 million m³ of sand, comparable to a volume of
8.400 Olympic swimming pools and a surface, just after construction,
of 180 football fields. The most observable meaning-making
processes in the interviews for this project were the ways in which
frames interacted. In the realization, one actor – the provincial
government of South-Holland – played a large role in convincing
other actors of his idea. This actor was very successful in framing
his message as such that other parties became advocates of the
proposed solution, too. The term ‘interpretive policy entrepreneur’
captures this ability. It describes an actor who can convince
others by making meaning in a way that they can easily relate to.
These case studies are not only relevant as stand-alone examples
of innovative nourishment schemes in the Netherlands. Through
comparing the projects with each other, I gained additional
insights (Chapter 9). In this comparison generalization of the findings
was not the objective, but seeing similarities and differences
between the cases. On the one hand, the comparison included
structural aspects of the projects, such as the way in which
higher governance levels supported the respective project and
the exchange between the political and scientific spheres. On the
other hand, I compared the three projects concerning their interpretive aspects. This included which arguments were important
in the decision-making processes, in how far the discussions
exceeded temporal, institutional and geographical scales, what
role interpretive policy entrepreneurs played, and what the character
of framing interactions across the cases was.
Based on the three empirical cases and their comparison,
conclusions can be drawn about the research questions (Chapter
10). Mega-nourishment schemes’ suggested multifunctionality
accelerated their adoption into the Dutch coastal management
repertoire (Research question A.). Multifunctionality is not only a
versatile argument allowing actors with different interests to connect
easily, but it also promises the mitigation of effects of coastal
squeeze. Advocates of mega-nourishment schemes had to convince
skeptics of the utility of experimenting with this technology
to prove that it was indeed multifunctional. In the Sand Motor
case, this experimental language was another adoption factor,
though inferior to the multifunctionality argument, which helped
advocates to realize the project. The influence of meaning-making
on decision-making processes can be understood as the ways in
which actor coalitions formed around specific interpretations of
policy problems and associated solutions (Research question B.).
In the three cases, I found framing processes contributing to such
coalition forming (“convergent”), and processes detracting from
it (“divergent”). Both types of processes can be employed deliberately.
However, these processes also occur subconsciously in
the natural manner of communication among humans through
framing. Due to more and more convergent meaning-making,
the coalition advocating mega-nourishment schemes stabilized
on different governmental levels and in different sectors. This has
leading to broad acceptance of mega-nourishment schemes in
Dutch coastal management.
The dissertation opens up at least three directions for future
research. First, the knowledge of interpretations and policy
processes can be translated into guidelines for practitioners.
Profound knowledge of frames, framing and the processes that
connect interpretations of policy situations to outcomes of projects
offers support for practice. Second, the research focused on
actors from governmental organizations, but left out societal
actors, e.g. non-governmental organizations, civil initiatives, or
the general public. Probing whether those groups also embrace the interpretations that would lead to successful implementation
may add valuable knowledge about the relation between governments
and their constituency. Third, it is relevant to study how
interpretations – in times when opinions challenge scientific findings
– influence the categorization of knowledge as ‘questionable’
or ‘undisputed’. Think of the way in which high-ranking politicians
doubt the existence of climate change.
In sum, this dissertation draws attention to the societal drivers
of coastal squeeze. Furthermore, it studies the adoption of a
coastal management innovation – the mega-nourishment scheme
– which may contribute to mitigating the effects of coastal squeeze.
On the one hand, this research’s meaning-orientation improves
our understanding of policy processes in Dutch coastal management.
On the other hand, it stresses the importance of meaning-
making as a basic cognitive process that is not only important
in policy-making, but just as much in everyday decision-making.
