Spatial Planning for Biodiversity in Europe’s Changing Climate
Elizabeth Wilson* and Jake PiperSchool of the Built Environment, Oxford Brookes University, Oxford, UK
ABSTRACTClimate change is already having impacts on biodiversity within Europe, with habitats and species needing to change and adapt to rising global temperatures and shifts in bio-climatic zones.
Spatial planning represents an important intervention to further European, national and local biodiversity objectives for climate change adaptation. Drawing on case-studies of plans for inland and coastal areas, and involving stakeholder workshops, this paper reports on a trans-national study examining the scope of spatial plans in the Netherlands, England and France in addressing the impact of climate change. It concludes that spatial planning is making provision for biodiversity and dynamic natural processes. However, while good practice in planning for biodiversity under conditions of climate change is developing, systematic use is not being made of available procedures. The paper examines some of the barriers to implementation of this new policy commitment to climate change adaptation. Recommendations are made covering policy development to include climate change impacts upon biodiversity, modifi ed procedures for plan-making and the appraisal of plans and projects. Amongst the specifi c measures recommended are the climate-proofi ng of projects and plans through the use of EIA and SEA; the integration of plans through adoption of common objectives and review of time horizons and boundaries; and an ecosystem-based planning approach.

Introduction
CLIMATE CHANGE HAS BECOME AN IMPORTANT ISSUE IN INTERNATIONAL, NATIONAL AND LOCAL
policy-making in the last decade (IPCC, 2001). The European Union has responded, adopt-
ing a Second Climate Change Programme in 2005 (ECCP II – CEC, 2005), but the principal
focus initially remains on mitigation of the causes of climate change, rather than adaptation to

unavoidable climate change. The impact of climate change on biodiversity has not been given as much
attention as might be expected, even though the EU has a well developed system of protection for its
landscapes and biodiversity, based on the Birds Directive of 1979 and the Habitats Directive of 1992
(CEC, 1979, 1992), which instituted the Natura 2000 network (see below).
The EU’s Biodiversity Strategy (CEC, 1998) sets a target of halting reduction of biodiversity by 2010,
but a number of reports suggest that biodiversity is continuing to decline (CEC, 2006a), and that imple-
mentation of the broad conservation policies is unsatisfactory (Beunen, 2006). Given the pressures on
biodiversity from a number of sources, especially land use change and development (EEA, 2003, 2005b,
2006a; English Nature, 2005a), the additional pressures of climate change present a real challenge for
EU biodiversity policy, and for policies for sectors such as spatial planning, which affect biodiversity.
This paper reports on a study undertaken as part of the BRANCH programme (Biodiversity Requires
Adaptation in Northwest Europe under a Changing Climate), funded by the EU Interreg IIIB pro-
gramme. It examines the spatial policies and plans of three member states in North West Europe
(France, the Netherlands and the UK (England)), and the framework provided by European policies,
strategies and legislation, in order to establish the effectiveness of mechanisms for assisting biodiversity
adaptation. Biodiversity adaptation is taken here to include processes whereby species and habitats either
move into newly suitable areas or where measures are taken to reduce vulnerability, increase resilience
and accommodate change. An aim of the policy review was to identify mechanisms that can be used
at European, national, regional and local scales to facilitate spatial planning for changing biodiversity
under conditions of climate and sea level change.
Spatial planning has a multitude of interpretations, and differs from the more narrowly defi ned land-
use planning. Faludi calls it ‘ambiguous – its meaning shifts over time’ (Faludi, 2002, p. 4), but it also
depends on the institutional and socio-legal context within which it is undertaken. It generally involves
the systematic preparation of policies, covering a particular spatial area, involving a range of activities and
interests affecting that space, and coherently worked out in advance of decisions. Promoted originally at
the level of the European Union through the European Spatial Development Perspective (ESDP), spatial
planning has been adopted at national, regional or provincial and local scales as a way of addressing the
‘spatial dimensions of a wide range of other sectoral policies, from economic development, transporta-
tion and environmental protection through to health, culture and language’ (Adams et al., 2006, p. 4).
The methodology of the current study included the review of EU policies and national policies
and planning documents at various levels, followed by consultation with policy-makers, planners and
other stakeholders at workshops in Winchester, The Hague and Brussels, and interviews in northern
France.
Climate Change, Biodiversity and Spatial Planning
Climate Change in Europe
Climate change modelling and socio-economic scenarios provide a complex picture of likely climate
change in Europe as a whole over the period to 2100 (Parry, 2000; EEA, 2003, 2004). Some European
regions seen as being most vulnerable to climate change impacts are the Mediterranean and southern
Europe, mountain and sub-Arctic areas, and densely occupied fl oodplains and coastal zones (EEA,
2006a).
Unavoidable change will happen over the coming 40–50 years as the result of past emissions, and
attempts to mitigate climate change via emission reduction cannot avert this. Projections for Europe
outlined by the EEA (2004) include an increase of annual mean temperature of +2.0–6.3°C over the
Spatial Planning for Biodiversity in Europe’s Changing Climate 137

period 1990–2100. Projections for precipitation show a 1–2% increase per decade for northern Europe
against an up to 1% per decade decrease in southern Europe.
Whilst precise prediction of changes is not yet possible, there is some consensus on warmer and drier
summers, and milder and wetter winters in NW Europe. Other changes in this region include more
frequent summer heat extremes, more frequent droughts and intense precipitation events and increased
risk of storms. In addition, the projected rate of sea level rise in the 21st century is 2.2–4.4 times higher
than in the recent past. At the local and regional level, the impacts of climate will depend on latitude,
topography and distance from the seas, as well as upon land use and settlement patterns. Spatial plan-
ning policies and measures must consequently fi nd ways to respond to this complexity.
There is already evidence of the impacts of a changing climate upon biodiversity: consequences
include phenological changes and loss of habitats and species, as well as species invasion and migration
(Brooker and Young, 2005). The European Environment Agency (2004) points to decreases in popula-
tions of certain plant species over the past three decades in northern and southern Europe, while plant
species diversity is increasing in northwest Europe with the northward movement of species, which is
projected to continue to the 2050s. Moreover, the EEA reports that ‘due to non-climate-related factors,
such as the fragmentation of habitats, extinction rates are likely to increase’ (2004, p. 51).
Adaptation to Climate Change: Biodiversity and Spatial Planning
There are many reasons why we need to adapt to climate change. The EEA argues that anticipatory action
is more effective than ‘fi re-fi ghting’ action; climate change may progress more rapidly than expected;
immediate and future benefi ts can be gained by ‘better adaptation to climate variability and extreme
climatic events’, and by avoiding policies and practices that constrain future options for adaptation.
(EEA, 2004, p. 79).
These arguments apply particularly to sectors such as water resources, and construction and develop-
ment, so that investments are resilient with respect to future change. However, questions remain about
the effectiveness of current protection for species and sites and wider ecological networks, as well as
questions about the long term ability of planned interventions (such as designated nature reserves) to
protect biodiversity under a changing climate.
The Natura 2000 Network was established to create a coherent European ecological network of sites
protected under the Birds and Habitats Directives, to ensure the restoration or maintenance of natural
habitats and species of Community interest at a favourable conservation status. The preamble to the
Habitats Directive makes reference to the role of land-use planning; Article 6 then sets out site protection
measures to be established by MSs across the network of sites. These include appropriate assessment,
the avoidance of disturbance or, eventually, compensation measures. Article 10 goes on to state that
Member States shall endeavour, where they consider it necessary, in their land-use planning and
development policies and, in particular, with a view to improving the ecological coherence af the
Natura 2000 network, to encourage the management of features of the landscape which are of major
importance for wild fauna and fl ora.
Such features are those which, by virtue of their linear and continuous structure (such as rivers
with their banks or the traditional systems for marking fi eld boundaries) or their function as
stepping-stones (such as ponds or small woods), are essential for the migration, dispersal and genetic
exchange of wild species (CEC, 1992).
European policies for biodiversity (such as the European Biodiversity Strategy, CEC, 1998) look to spatial
planning to help protect and safeguard internationally and nationally designated sites, networks and

species, as well as locally valued sites in urban and non-urban areas, and to create new opportunities for
biodiversity through the development process. However, the BRANCH project has shown that those who
are developing conservation policy are unsure about the current effectiveness of such policy, and about
what is the future for protected areas. It is acknowledged amongst conservationists that many sites are
at risk as the areas are too small and fragmented, whilst the target species (i.e. those for which the site
was designated) may not be resilient to changing climate. It is argued by many (such as Hossell et al., 2000, 2001; Gaston et al., 2006) that this site-based approach does not really acknowledge the dynam-
ics of change in the wider environment. Green et al. (2001, p. 67) argue that under changing climatic
conditions ‘the maintenance of the current scientifi c interest of statutorily designated sites may prove
diffi cult or even inappropriate’ and Ibisch (2005, p. 1) concludes that ‘in the light of projected climate
changes and short-term loss of stability for many species, it is highly improbable that Natura 2000 alone
can accomplish its objectives’.
Not only is the species composition of the designated sites likely to change, but the potential for
habitats and species to move in response to climate change is likely to be constrained by other land-use
changes, some of them driven by climate change. For instance, if the availability of water resources for
urban populations declines, then the need to develop new water resources may create additional stress
on water systems and the biodiversity that depends on them.
Conservationists and conservation bodies have proposed a number of policy changes that aim to make
European ecosystems more resilient to climate change: the European Environment and Sustainable
Development Advisory Councils (EEAC, 2005), for instance, have called for continued development of
the Natura 2000 network, stressing the importance of conservation planning across whole landscapes,
enhancing ecological connectivity and recreating ecosystems on a large scale. Similarly, Vos (2005) has
proposed more robust corridors and networks at a national and international scale, with enlarged nature
conservation areas, and others (Opdam et al., 2006) argue for a coherent large-scale spatial structure
of ecosystems, such as regional-scale ecological networks. Spatial planning is likely to be a key means
of delivering this.
Planning Strategies and Approaches for Biodiversity Under Climate Change
Research Approach
The BRANCH study sought to examine the extent and effectiveness of current spatial plans and planning
measures in aiding or promoting biodiversity adaptation. It interpreted spatial planning as involving
the setting of goals and implementation of actions for the short and longer term of land uses and land-
based activities and their interactions. The scope of the study included terrestrial and coastal planning,
but not planning for the wider marine environment.
The research approach was to identify published strategies and policies, but also, given the questions
about the effectiveness of conservation policy mentioned above, to examine stakeholders’ attitudes to the
issues arising from their implementation. Box 1 aims to clarify terms used in this paper. The documen-
tary review covered the EU policy framework and national, regional and local/municipal spatial plans
and policies and plans in the three EU member states participating in the BRANCH project – France,
the Netherlands and the UK (England) – as at 2005. It examined their treatment of the interaction of
climate change with biodiversity and wider natural processes such as landscape change, natural resource
use, management of water and coastal zones. Plans for designated sites at national, regional and local
level were reviewed, as well as plans for coastal zone management. Case studies were used to examine
the issues arising from climate change impacts in urban and rural, coastal and inland sites, and to
explore the planning measures in place.
Spatial Planning for Biodiversity in Europe’s Changing Climate 139

Key stakeholders in the fi elds of spatial and biodiversity planning were contacted for information on
relevant plans and policies, and for their views on biodiversity adaptation, on any obstacles to implemen-
tation of adaptation policy and on possible future measures to address these. The stakeholders included
staff of environment and conservation agencies, spatial planning and environment ministries, planners
at regional and local levels, staff of organizations and authorities with responsibilities for managing
protected and other sites and environmental non-governmental organizations.
Two national workshops were held in 2005, in England and in the Netherlands. Participants represent-
ing both planning and biodiversity bodies were invited to discuss a structured set of topics to identify
current awareness of climate change and biodiversity, the obstacles to better spatial planning to enable
adaptation by species and habitats and what is needed to overcome these obstacles (including policy
development and practical measures, information and tools needed). Interviews with policy-makers in
France were held to present and analyse the fi ndings on the shortcomings of current practice.1 Perceived
shortcomings and issues in spatial planning at EU and national level were discussed with a group of
policy analysts and policy-makers working at EU level.
Criteria for Review of Spatial Planning Documents
The study reviewed how far strategies, policies and spatial plans at national, regional or provincial and
local level, across the BRANCH partner countries, consider the implications of climate change for bio-
diversity, including the implications of policy for the conservation and safeguarding of designated sites,
and the provision of opportunities to assist biodiversity to adapt to these changes.
The research approach recognized that plans differ in their level of detail. We distinguished between
framework or policy plans (such as regional strategies) and those proposing specifi c measures (such as
action plans for coastal zones). The literature covering aspects of climate change is growing, but there
is still little on the three-way relationship of spatial planning, climate change and biodiversity. The selec-
tion of the assessment criteria therefore drew on the literature on climate change and spatial planning
(such as ODPM, 2004), on biodiversity and spatial planning (such as EEA, 2003; CEC, 2006b; Byron
and Treweek, 2005), on climate change and biodiversity adaptation (such as Hossell et al., 2001; EEA,

2004, 2006b; Brooker and Young, 2005; Hulme, 2005) and on climate change adaptation generally
(such as EEA, 2004; West and Gawith, 2005).
Spatial planning works to a range of time-horizons: national or regional level plans may have horizons
of up to 25 years, or even longer for some functions such as coastal zone management planning, with
local plans having a shorter timescale. However, as built development is likely to persist over 60–100
years, and in some cases longer, it is important that spatial planning takes account of the changing
climate that will be experienced throughout the 21st century. The research therefore examined the time-
horizon of plans. The criteria used are shown in Box 2.
Spatial Planning, Biodiversity and Climate Change in the BRANCH Partner Countries
The fi ndings from the three BRANCH partner countries are described, before the broader issues are
drawn out. More details, particularly of the case studies, are to be found in the full BRANCH report
(Piper et al., 2006). The case study examples were proposed by the BRANCH project partners to illustrate
some of the current tensions and issues in responding to climate change, and to demonstrate aspects
of changing practice.
FranceFrance adopted a Strategy for Sustainable Development early in 2003 (MEDD, 2003), with a fi ve year
timetable, which emphasized the need to reduce the causes of climate change, but not the need for
adaptation to its effects. A serious heat wave later that year prompted considerable research and policy-
making initiatives. The French national plan on climate change (MEDD, 2004) states that ‘Adaptation
should bring together national policy with local level approaches in order to take account elements
linked to climate in the different decision-making mechanisms’. The Plan committed government to an
adaptation programme, published in 2005 (ONERC, 2005), which discusses in general terms the need
for measures to enable biodiversity to adapt, as well as to further research.
The French spatial planning system emphasizes the responsibilities of higher or more strategic
territorial levels with respect to climate change; the lower or more local levels had not yet taken action
with respect to either mitigation or adaptation (in 2006). As with the other BRANCH partner coun-
tries, there is a complex array of governmental agencies responsible for spatial planning, economic

development, coastal management and biodiversity, and new initiatives are underway for integrated
coastal planning.
A study of climate change impacts on sites owned by the Conservatoire du Littoral (Clus-Auby
et al., 2005) identifi ed the Baie des Veys, Basse Normandie, as one of the Natura 2000 sites particularly
vulnerable to sea-level rise and coastal fl ooding. The review of plans in this case-study area (Commis-
sion Locale de l’Eau, 2004; Prefectures of Haute-Normandie and Basse-Normandie, 2004) revealed
little evidence as yet of clear integration either horizontally between plans or vertically between levels of
planning, or of the use of integrative tools such as SEA or appropriate assessments under the Habitats
Directive. However, spatial, regional and water management plans are currently being developed that
affect the Baie des Veys site, including an overall spatial planning strategy for the Seine estuary. Coastal
fl ood risk management has traditionally adopted the hard engineering approach, but policy-makers are
recognizing the need for an understanding of dynamic coastal processes and appropriate action.
Considerable plan-making activity is now addressing some of the issues: territorial climate plans are
being prepared that will address mitigation, and the next round of regional plans will address climate
change adaptation. The focus of the climate change research organization, ONERC, is on the bio-physical
regions of mountains and coasts, and on the impact on sectors such as forests, viti-viniculture, build-
ings and public health.
Despite these signifi cant shifts in approach, stakeholders interviewed pointed to mixed and complex
messages on climate change, with the link to biodiversity rarely made. They felt there was a low level
of understanding of climate change adaptation at all levels of the planning hierarchy, with poor com-
munications and piecemeal availability of biodiversity data. It was felt at that time – Spring 2006 – that
staffi ng and fi nancial resources available for this policy area were low.
The NetherlandsThe Dutch have a long-standing history of national action on sustainable development, with the Fourth
National Environmental Policy Plan (Ministry of Housing, Spatial Planning and Environment, The
Netherlands (VROM), 2000) acknowledged as the precursor of a sustainable development strategy (on
which the government consulted in 2002). NEPP4, which had a planning horizon of 30 years, identifi ed
climate change as a key issue. The national response to climate change is increasingly characterized
by the integration of policies across a wide range of policy spheres, with a commitment to fl exibility
in spatial planning for the future. This approach is found in the National Spatial Strategy Nota Ruimte
(VROM, 2004), which outlines policies up to 2030. The Strategy identifi es a range of measures aimed
at preventing, but also adapting to, the effects of climate change while achieving residential, commercial,
recreational and ecological goals.
The Dutch tradition of land reclamation, and making room for people, is giving way to a signifi cant
and revolutionary national shift in policy to making room for rivers (MVW, 2000a; De Vries, 2006). This
has two elements: ensuring that the ecological functions of the water system provide the foundation for
spatial planning decisions (such as through the requirement for a Water Test, under which each provin-
cial and local spatial plan has to consider the issues of water storage and retention in the plan), and the
pro-active designation of areas for the permanent or temporary storage of water. SEA was undertaken
of the Space for Rivers policy, which concluded that it would have positive impacts on natural dynamics
and ecosystems (Kolhoff and Slootweg, 2005). The national policy towards coastal zone management
(MVW, 2000b), sets out short- (<5 years), medium- (<30 years) and long-term (up to a century) policies,
and specifi cally considers the consequences of rising sea-levels as a result of climate change. There is
a shift underway towards policies that promote working with dynamic coastal processes, but particip-
ants at the workshop in The Hague did not consider that these are suffi cient to integrate biodiversity
objectives into spatial planning.

The Netherlands has also been innovative in biodiversity planning. A long-standing policy, origi-
nally launched in 1990, has been to establish a National Ecological Network (NEN), which looks to
spatial plans (especially at the provincial level) to implement the network and determine biodiversity
conservation objectives (MLNV, 2000). The principles are to enlarge existing biodiversity conserva-
tion areas, to develop new areas and to develop local ecological corridors. The NEN was proposed as a
response to habitat loss and fragmentation (though not climate change – Hootsmans and Kampf, 2004).
Later, to improve spatial cohesion, provincial governments were asked to explore a set of ‘robust cor-
ridors’. Kolhoff and Slootweg (2005) consider that the network provides an important frame for the
consideration of biodiversity in spatial plans, and that overall it is a successful means of extending
conservation areas. However, priority is given to the realization of the NEN; non-designated areas also
perform valuable ecosystem functions, but they receive less attention.
At the provincial level, the Provincial Water Management Plans take account of climate change;
there is evidence of cross-boundary and inter-provincial co-operation on climate change issues and
adaptation for climate change is increasingly recognized. An example is the Provincial Environmental
Plan for Limburg (Provincial Council of Limburg, 2001), which highlighted water management issues,
and approved the Limburg ‘robust corridor’. The corridor links a chain of habitats along the east bank
of the River Maas/Meuse, and a signifi cant part of it has Natura 2000 status. The corridor has been
reviewed within preparations for the next Environment Plan for Limburg, to provide a Strategic Policy
Framework due in 2007: consultation is underway, but decisions (such as on acquisition and funding)
are still to be made.
Despite what seems to be innovative and long-term strategic provision in the Netherlands, stakehold-
ers at the national workshop raised a number of concerns over implementation. They considered that
the link between climate change and biodiversity is not fully apparent. The issue of water and safety is
a key issue, but the Water Test faces institutional obstacles (LUC et al., 2004). There are also problems
of negotiating for and acquiring land for water storage (De Vries, 2006).
The UK (England)At national level, climate change is recognized as an important and current issue, not merely one of
interest in the long term (HM Government, 2005). There is no national spatial plan for England (unlike
the position in Wales and Scotland), and planning horizons have been generally short. General guidance
on the response of planning to climate change has been published (ODPM, 2004). The government
has consulted on a new policy on making space for water, developed on the Dutch model (DEFRA,
2004), with policy implications for restoring the natural dynamics of rivers and fl ood-washlands, and
hence scope for improvement in wetland and riverine habitats. In 2006 this led to the revision of exist-
ing planning policy on fl ood risk and development (ODPM, 2001) to put more emphasis on protecting
fl oodplains and introducing institutional change, making the Environment Agency a statutory consultee
on fl ood risk for certain developments (Department for Communities and Local Government (CLG),
2006a). National spatial planning policy for biodiversity takes account of the Natura 2000 Network and
wider conservation principles (PPG 9 and more recently PPS9), though PPS9 simply states that regional
plans need to take climate change into account (ODPM, 2005).2
The England Biodiversity Strategy (DEFRA, 2002) is similarly unspecifi c about the more general
role of the towns, cities and development sector in biodiversity adaptation to climate change, but the
2 Offi cial government planning policy subsequent to the present study, the draft Planning and Climate Change supplement to PPS1 on sustain-able development (CLG, 2006b), reiterates that regional planning bodies and all planning authorities should ‘sustain biodiversity, and in doing so recognize that the distribution of habitats and species will be affected by climate change’.
Spatial Planning for Biodiversity in Europe’s Changing Climate 143
Copyright © 2008 John Wiley & Sons, Ltd and ERP Environment Eur. Env. 18, 135–151 (2008)DOI: 10.1002/eet
climate change element of the strategy was reviewed in 2006–07. In the coastal zone, however, the
nature conservation agencies and fl ood defence agencies recognize the need to act in ways that respond
in a dynamic manner to climate change as illustrated by the shift in policy from coastal protection to
working with natural coastal processes and ‘managed realignment’ in circumstances where ‘holding the
line’ is recognized as no longer sustainable (English Nature, 2005b). The integration of this approach
into spatial planning policy is nevertheless a lengthy process of plan-making and negotiation.
At the regional level, new regional spatial strategies are being prepared, which look to 25 year time-
horizons. Climate change is explicitly recognized in these strategic plans, and specifi c strategic landscape
measures have been devised in some regions. For example, the Draft South East Plan (SEERA, 2005a)
includes policies specifi cally promoting climate change adaptation, and proposes policies for areas of
strategic biodiversity opportunity. The draft sustainability appraisal of the plan (SEERA, 2005b), which
aims to fulfi l the requirements of the SEA Directive, identifi es climate change as a critically important
issue, but considers that further work on adaptation needs to be fast-tracked to inform the implementa-
tion of the plan.
At the local level, some plans now include proposals for the creation of landscape features, such as
stepping-stones and green corridors, and to consolidate existing networks linking wildlife sites. Addi-
tional spatial measures undertaken to protect and promote biodiversity are the restoration and enhance-
ment of rivers and wetlands, but, as indicated, this is not yet a national requirement. The case study of
Queenborough and Rushenden, a regeneration area in North Kent on the Thames estuary, showed that
forward planning for biodiversity under a changing climate was taken into account in the Masterplan
(DEFRA, 2006). The aim was to allow natural processes to continue, with the expectation of some fl ood-
ing being planned for, with core green and blue (terrestrial and water-related) infrastructure integrated
into the site, with minimal barriers to movement of water and species, and a network of permeable
habitat spaces, corridors and links.
Review of EU Policy
The policy framework set by the European Union is also of evident importance, especially for biodiver-
sity. Strategies and procedures for the assessment of plans’ impacts on biodiversity (such as the Direc-
tives on Habitats (92/43/EEC), Strategic Environmental Assessment (2001/42/EC) and Environmental
Impact Assessment (97/11/EC) and the Water Framework Directive (2000/60/EC)) were therefore also
reviewed. Although the European Union does not as such have a specifi c mandate for spatial planning,
it does publish relevant initiatives such as the European Spatial Development Perspective (CEC, 1999)
and thematic strategies such as that on the urban environment (CEC, 2006b), which the study briefl y
reviewed.
Almost all EU spheres of competence have potential for indirect impacts upon the environment
(such as agriculture policy, industrial policy and transport policy), but this research concentrated upon
those aspects of policy that can be used to support spatial planning action to protect biodiversity under
a changing climate. Impacts from and interactions with other policy areas are being explored within
the MACIS project.3
Land use planning is outside the formal competence of the EU. Nevertheless, the EU has recently
adopted a thematic strategy on the urban environment (CEC, 2006b), a commitment in the Sixth Envi-
ronmental Action Plan. This strategy provides guidance on integrated environmental management,

(land-use planning), the loss of natural habitats and impacts such as soil-sealing (i.e. creation of hard
surfaces, impermeable to precipitation), and the promotion of urban biodiversity. It does not expressly
mention the role of spatial planning in assisting biodiversity to adapt to climate change.
The emerging sustainable communities agenda may also be important for improving the resilience
of biodiversity to climate change. The Leipzig Charter on Sustainable European Cities (German Federal
Ministry of Transport, Building and Urban Affairs (BMBVS), 2007), which builds on the 2005 Bristol
Accord, refers to the need to improve the quality of the environment but is less specifi c than the earlier
Accord on biodiversity and habitats.
The fi rst European Climate Change Programme (ECCP) was chiefl y concerned with the reduction of
greenhouse gas emissions in line with Kyoto Protocol targets. Adaptation will form a more signifi cant
part of ECCP II, with objectives including the integration of adaptation into appropriate policy areas,
such as biodiversity, urban planning and construction (CEC, 2005). The EU has not so far been at the
forefront of climate change adaptation, and it is acknowledged by the European Environment Agency
(EEA, 2005a) that climate change considerations have not yet been integrated to any great extent into
the key EU environmental policies, nor into economic, regional or agricultural policies.
Emerging Issues: Achievements and Barriers
Achievements and Shortcomings
On the basis of the policy review, workshops and interviews, the study concluded that the place of
dynamic biodiversity is becoming more fully realized within spatial planning in the three countries.
Plans are recognizing the importance of ecological networks at European and regional scale, to counter
the issues of fragmentation and isolation, and are beginning to include measures that aid the devel-
opment of a matrix of non-protected areas (including urban areas) across the wider landscape. Plan
horizons are growing longer, and measures are in place (particularly prompted by the needs of water
systems) to deal with cross-boundary issues. Box 3 shows some of the progress at provincial and regional
scales (not yet at a European scale).
While spatial planning is acknowledging the wider context for dynamic biodiversity, there is less
evidence of direct response to the needs of climate change adaptation.
Safeguarding new sites specifi cally for climate change adaptation is rare (except through land acquisi-
tion by NGOs). Compensatory provision under the Habitats Directive is being used, but again this is
geared to retaining favourable conservation status under change caused by drivers other than climate
change (such as port development). SEA is not being used systematically to address impacts under a

changing climate. Climate change impacts may act cumulatively and synergistically with impacts result-
ing from other sectors or with other pressures (such as policy or demographic change), but typically
there is little identifi cation or assessment of cumulative impacts.
Overcoming Barriers
In any area of policy there are issues of implementation arising from the different ways in which policy is
framed and interpreted, infl uenced by the distribution of power across institutions and policy networks,
styles of regulation, and understandings and attitudes to knowledge (Hill, 2005; Beunen, 2006). This
is especially so in this case where different policy communities – here, those of spatial planning and
of biodiversity – are responding to a European requirement for ecological protection, while also begin-
ning to take on a new and uncertain policy area of climate change adaptation. The BRANCH research
therefore aimed to identify any barriers that inhibit the adoption of more effective policies and measures,
in the two areas of plan-making and the use of tools and knowledge. Box 4 summarizes these barriers,
which are discussed further in the following paragraphs.
Many plans (with the exception of some Dutch plans) are relatively short term in comparison with the
period over which climate change is forecast (for instance, 5–10 years in comparison with predictions
made for climate change over the coming century). Spatial plans that are not able to conceive of signifi -
cant future changes, for instance in the quality and distribution of biodiversity, are not able to take pre-
emptive action now. Amongst both scientists and policy-makers, the lack of consensus about appropriate
intervention measures, and uncertainty surrounding their outcomes, is an obstacle. Sustained habitat
creation is diffi cult, and biodiversity response cannot be planned exactly, but there was consensus that,
in order to enable biodiversity to be maintained, plan objectives need to recognize dynamic processes,
with protection of existing semi-natural habitat, the creation or re-creation of habitat targeted to increase
the potential for connections between sites, and a more ‘permeable’ landscape. This would require a
strategic and fl exible approach with land earmarked and safeguarded for biodiversity.
Implementation powers and means (such as resources) are also necessary to fulfi l objectives. Powers
and competences to prepare and implement spatial plans vary across member states and across different
spatial scales. For instance, in England, central government has powers to ensure conformity by lower
(regional and local) tiers by means of national statements of policy, and through plan approval. In the
Netherlands, a national spatial planning framework sits alongside strong provincial plan-making powers,
while in France regional plan-making powers exist but are less used (CEC, 1997).
The study found that planners in England and the Netherlands do not have powers for direct
implementation of appropriate measures (these might include designating areas with potential for
rehabilitation and protection as biodiversity habitat in the future), but generally must rely on indirect
implementation, for instance via negotiations, or planning conditions and obligations. Not all existing
plans are statutory in nature – the implementation of non-statutory plans is not guaranteed. Moreover,
• Plan horizons too short (e.g. 5–10 years)• Lack of consensus on intervention measures• Uncertainty on climate change impacts• Diffi culties with habitat creation (ecological, fi nancial and inadequate authority)• Confl icts between different plans and interests of different sectors• Boundary issues (boundaries do not coincide)• Existing tools not fully utilized (SEA, AA)

146 E. Wilson and J. Piper

confl icts between overlapping plans and initiatives, especially in coastal zones, and poor integration of
social, economic and environmental objectives, have led to potential for confl icts between policy aims.
Plans typically call for partnerships, and within these partnerships such topics as economic development,
tourism or land protection interests may dominate biodiversity interests. Water-related activities such
as inter-catchment transfer, reservoir building and water abstraction may have signifi cant consequences
for aquatic, wetland and terrestrial biodiversity, especially where affected by drought. Where fl ooding
(fl uvial, groundwater or coastal) has been severe in recent years, this has acted as a trigger for action on
climate change, but it is not clear that policies to enhance security from fl ooding will lead to a higher
profi le for biodiversity.
Implementation is also affected by boundary issues: administrative and functional boundaries rarely
coincide with the natural boundaries that are relevant to wildlife. This is an issue at both local and also
international level, such as the Rhine and Maas in The Netherlands, where for example, the species
that are the principal conservation objective of the Natura 2000 sites might cross borders in response
to climate change. There are also issues over changing site boundaries as coastlines and rivers change.
However, the River Basin Management Plans under the Water Framework Directive are catchment
based, and can provide a model for cross-boundary ecosystem planning. In the wider landscape, plan
objectives are limited by a lack of permeability, insuffi cient space for biodiversity and the fragmentation
of landscapes via infrastructure and other development. It is increasingly recognized (DEFRA, 2002)
that the network of parks, gardens, semi-natural and brownfi eld sites in urban areas is important for
biodiversity. However, for species with poor dispersal capacity, providing permeable landscapes will not
be suffi cient to help them to move.
Existing tools, such as SEA and Appropriate Assessments under Article 6 of the Habitats Directive,
are not being used systematically to consider the impacts of climate change (indeed, climate change is
not expressly mentioned in the directives). However, strategic levels of assessment have been identifi ed
in international agreements relating to biodiversity (the Convention on Biological Diversity, the Ramsar
Convention on Wetlands and the Convention on Migratory Species). Treweek et al. (2005) argue that
SEA can be an important tool for ensuring that conservation and sustainable use of biodiversity are
pursued as fundamental objectives of strategic decision-making and planning, and Kolhoff and Slootweg
(2005) show that this has been effective in the Netherlands. The BRANCH review suggests that SEA
could be used more explicitly to promote the conservation and sustainable use of biodiversity under
climate change. The impact of the plan or programme should be assessed against a changing climatic
context, over time, taking into account the proposed mitigation measures (to reduce plan impacts). The
likely effectiveness of compensatory measures must also be assessed in the light of climate change. If
climate change impact assessment becomes a standard element in the SEA process, then these benefi ts
could be gained and directed towards adaptation for climate change. Guidance is available on SEA and
climate change (Levett-Therivel et al., 2004), and on the treatment of climate change within Appropriate
Assessments (Scott Wilson et al., 2006). Other potential benefi ts of SEA relate to areas outside protected
sites and opportunities to implement biodiversity initiatives pursued by local stakeholders, NGOs and
other partnerships.
It is also important to consider the role of spatial planning within the wider context of public opinion.
Public awareness of climate change has been stimulated by weather events, such as the French heat wave
of 2003, and fl ooding events. Whilst the public may now be more aware that some degree of climate
change is unavoidable, it is less aware of likely impacts upon particular sectors, for example, impacts
upon biodiversity. Public interest in biodiversity is variable, though many public campaigns (such as
the Natuurkalendar on phenology in the Netherlands) appear successfully to promote interest. Linked
to this is a conservative sensitivity about change, especially in treasured landscapes, which may be an
obstacle to early adaptation.
Spatial Planning for Biodiversity in Europe’s Changing Climate 147

Conclusions
The BRANCH review concluded that spatial plans should recognize that biodiversity offers both important
direct and indirect benefi ts through the inherent value of species and habitats, biological products and eco-
system services, as acknowledged, for instance, in the EU’s review of the implementation of its biodiversity
strategy (CEC, 2006a). Benefi ts include maintaining the quality of land, air and water, and maintaining the
role of wetlands in fl ood mitigation (EEA, 2003). Biodiversity also contributes signifi cantly to the distinctive
quality of places, and to people’s quality of life, health and well-being. Thus, in circumstances of climate
change, spatial planning has a particularly important duty to put in place measures that directly protect
and enhance biodiversity, and measures that control the impacts of human activities, or safeguard areas
of current or future importance for biodiversity. Many of these measures will also provide other benefi ts
both for the support of ecosystem functions and for human quality of life.
It is diffi cult to attribute actions to policies, and to judge outcomes when the criteria for effectiveness of
successful implementation may be unclear (Beunen, 2006; Gaston et al., 2006). Moreover, conclusions
from cross-national studies need to acknowledge that regulatory, institutional and professional cultures
vary across nations, and inferences must be tentative. The principle of the BRANCH project has been
to examine the impacts of climate change from an international perspective, and to share experience
and knowledge to fi nd transferable results, and to strengthen transnational co-operation in the fi eld of
spatial development planning. While the review has shown how circumstances differ between the three
partner countries, it has also shown how climate change will continue to affect northwest Europe in
signifi cant ways, and that all member states face similar issues in the implementation of international
and European legislation for biodiversity protection.
The understanding of the interaction of climate change, biodiversity and spatial planning at the
European level is changing. Until recently, the focus has been upon mitigation through the Kyoto process
and achieving emissions targets. This position is shifting, with reforms such as the ECCP underway,
and support for research into the impacts of climate change on biodiversity across Europe (Harrison
et al., 2006). Key legislative and policy instruments (such as directives and strategies) have considerable
potential for addressing climate change adaptation, and supporting the further policy responses now
under development. The review underlined the need for fl exible responses to changing environments
and biodiversity, with stakeholders also seeking action in the wider landscape to enhance adaptive capac-
ity through networks, and to improve the habitat quality, viability, resilience and permeability of the
matrix of land between protected areas.
The BRANCH project has identifi ed research needs across a broad scope: examination of the interac-
tions between climate change impacts and other pressures for change (for example, demographic and
economic change) and the indirect effects of these upon biodiversity, as well as biodiversity research (for
example, species’ dispersal capabilities). Another fi eld of work would cover spatial planning approaches
(such as ICZM and integrated fl ood management) to identify measures suitable for different environ-
mental and economic circumstances; other areas include partnership approaches, training and skills
upgrades and communication methods – including web-based GIS methods. Also important is analysis
of the interplay of the sectoral policies (transport, agriculture, water) with spatial planning and biodiver-
sity, in order to identify approaches that more effectively bring win–win–win solutions, with benefi ts
for mitigation, adaptation and biodiversity.
At the national level, spatial planning policies and measures for promoting dynamic and changing
biodiversity, and for wider ecological networks, are being implemented.
Nevertheless, it is clear that there are challenges to placing biodiversity adaptation at the heart of
spatial planning. Climate change presents particular problems of lack of certainty and knowledge of the
148 E. Wilson and J. Piper

extent, rate and type of changes and the necessary interventions to secure biodiversity. In addition, there
are signifi cant problems in promoting a longer-term view for spatial planning when political horizons
are short, and in adopting suffi ciently robust language to address climate change effectively (Wilson,
2006; Bulkeley, 2006). Even if some barriers to implementation were overcome, concerns remain that
the wider political and economic context, expressed for instance in the Lisbon agenda promoting EU
competitiveness, may be an obstacle to appropriate action and policy evolution on climate change and
biodiversity.
