CULTURAL LANDSCAPES
European landscapes have been transformed for millennia. Initially, woodlands were
cleared to allow for agriculture. Scattered all over Europe there are core regions,
where agriculture started early and has always been practised intensively. Peripheral
regions characterised by unfavourable stand qualities were cultivated less intensively.
During the last centuries land reforms were carried out in the core regions in particular,
whereas many peripheral regions were abandoned. In a cultural process, influenced
by romanticism, remnants of less intensively used landscapes were regarded as "nature".
Today, it is more and more acknowledged, that the protection of nature and the preservation
of cultural landscapes require different strategies. Dynamics characterises natural
systems. Therefore, dynamics must be protected as an important quality in nature
reserves. A cultural landscape should be stable. But natural processes (growth, succession)
also govern cultural landscapes. Man counters these natural processes by ploughing,
harvesting, wood cutting etc. Because natural conditions differ between European
countries different means to counter natural process where developed resulting in
different cultural landscapes. Differences between cultural landscapes are threatened
to be levelled by modern land use practices. The characteristics of different European
cultural landscapes as important parts of the cultural identities of different European
countries will be explored.

AGRICULTURAL POLICIES SUSTAINING THE EUROPEAN COUNTRYSIDE
Agricultural policies are mainly determined at the EU level and cover a broad range
of objectives, extending beyond production related concerns to other social and environmental
functions. Since the mid 1980s there have been increasingly explicit references to
countryside management and other environmental concerns in agricultural policy. Of
particular importance has been the growth of incentive policies whereby farmers receive
annual payments in return for accepting agri-environmental obligations. The evolution
of these initiatives to integrate the environment into the Common Agricultural Policy
(CAP) will be examined and placed in the wider context of agricultural policy and
the changing relationship between farm practice and environmental outcomes. The primary
role of incentives in agricultural policy will be considered alongside the use of
other policy instruments, such as regulatory controls and land use planning. Some
of the strengths and weaknesses of agricultural policy as a means of influencing
countryside management have become apparent over the last two decades. There are
implications both for environmental policy and for agricultural policies seeking
to support ‘multifunctional’ farming.

AGRI-ENVIRONMENT SCHEMES DO NOT EFFECTIVELY PROTECT BIODIVERSITY IN DUTCH AGRICULTURAL
LANDSCAPES
Approximately 20% of the EU’s farmland is under some form of agri-environment scheme
to counteract the negative impacts of modern agriculture on the environment. Although
in various countries agri-environment schemes have been implemented for well over
a decade, to date, no reliable, sufficiently replicated studies have been performed
to test whether such measures have the presumed positive effects on biodiversity.
Here we present the results of a study evaluating the contribution of agri-environment
schemes to the protection of biodiversity in intensively used Dutch agricultural
landscapes. We surveyed plants, birds, hover flies and bees on 78 paired fields that
had either management agreements or were managed conventionally. Management agreements
were not effective in protecting the species richness of the investigated species
groups: no positive effects on plant and bird species diversity were found. The four
most common wader species were even observed less frequently on fields with management
agreements. On the other hand, hover flies and especially bees showed modest increases
in species richness on fields with management agreements. The results indicate there
is a pressing need for a scientifically sound evaluation of this management tool.

LAND-USE AS THE PRECONDITION FOR INCREASE AND MAINTENANCE OF BIODIVERSITY
IN GRASSLAND ECOSYSTEMS
Low-intensity use is a precondition for the maintenance of grassland biodiversity
and recreational value in central and western Europe. Since the neolithikum, grazing
and mowing has moulded specific and highly diverse animal and plant communities associated
with nutrient poor meadows and pastures. Communities that did not exist in pristine
landscapes that were covered by forest. Meagre grassland has declined considerably
as a consequence of modern and intense agriculture. However, some mountain ranges
in western and central Europe have retained fair chunks of meagre grassland. Preservation
of these highly diverse grasslands has become obligatory following the Rio convention
on biodiversity and the European Flora-Fauna-Habitat directive. Preservation requires
the integration of nature conservation and land-use (livestock). Examples from Nordrhein-Westfalen
will be presented that show (a) the integration of conservation targets into farming
operations (more than 200 farms); (b) successful preservation of high-level regional
grassland biodiversity; (c) additional income for farmers (4,000 - 15,000 Euro per
year) based on adequate compensation programs; and (d) as a result increasing identification
of farmers with conservation goals.

THE PIG GRAZING PROJECT: PROSPECTS OF A NOVEL MANAGEMENT TOOL
Until the beginning of the last century domestic pigs were mainly kept outdoors.
They were guarded by herdsmen. Density of pigs was often quite high. For example
in autumn during the 16th-17th century each year up to 200.000 pigs were fed on acorns
in a single German forest (10 000 ha). During other parts of the year, they were
kept in pastures feeding on grasses and herbs, and rooting the soil in search for
sub-surface food. Our research demonstrates that rooting (a foraging behaviour unique
to pigs) opens patches of soil that provide habitat qualities essential for the establishment
of several species. Within 1-2 years after pigs were introduced the diversity of
plants increased by up to 30 % in low-intensity pig-pastures (<2 pigs/ha). Several
rare and endangered plants (e.g. Caltha palustris, Elatine triambra, Oenanthe
fistulosa) and animals (e.g. Gallinago gallinago, Crex crex, Anthus pratensis)
were promoted. Grazing pigs - in particular old regional breeds - attract spectators
('eco'-tourism). They therefore function as an efficient marketing tool for regional
products gained from conservation oriented land-use. Thus, pig grazing can generate
income for products from low-intensity farming.

ALDO LEOPOLD ON THE ETHICAL AND AESTHETIC FOUNDATIONS FOR CONSERVING FOREST
BIODIVERSITY
In the 1930s and 1940s, the ecologist Aldo Leopold argued for new values that would
harmonize human behavior in industrial societies with the earth's ecosystems. Since
that time, Leopold's land ethic has provided one conceptual foundation for environmental
ethics and been widely influential
in such disciplines as forestry and wildlife science. This presentation examines
the predominant form of conservation thinking that prevailed in American forestry
during Leopold's day and is still influential, namely, the utilitarian and agronomic
philosophy of Gifford Pinchot. It then reviews
Leopold's writings to evaluate the new ethical model that he proposed for forestry
and forestry land use. It argues that, in contrast with "Pinchotism," Leopold's
"biotic forestry" provides a sound ecological and aesthetic basis for such
critical goals as preserving forest biodiversity and maintaining forest ecological
health. It also notes Leopold's emphasis on such measures as transforming the attitudes
of individual land owners and users, altering university education, and creating
new government conservation programs. It concludes that preservation of the remaining
forest biodiversity in the world must also take into account some of the institutional,
cultural, and economic barriers to ecologically intelligent land use.

LEGAL BASIS OF LAND USE AND CONSERVATION UNDER THE EC HABITATS DIRECTIVE AND
THE US ENDANGERED SPECIES ACT
Are the EC Habitats Directive and the US Endangered Species Act effective legal instruments
to protect landscape diversity? The EC Directive obliges member states to designate
sites that host certain natural habitat types (estuaries, bogs, beach forests, etc.)
and/or certain endangered species as a special area of conservation (SAC). After
designation as an SAC, member states have to: 1) draw up conservation measures, 2)
take preventive measures to avoid deterioration by existing activities (i.e., agriculture,
fisheries), 3) prohibit plans or projects with negative effects on the SAC (i.e.,
construction works). Apart from these rules on SACs, the Directive also gives rules
on the protection of endangered species outside SACs (for instance, prohibition to
destruct breeding sites). In the US, the Endangered Species Act applies to a list
of endangered or threatened species. The law prohibits any action that results in
a ‘taking’ of a listed species, or adversely affects habitat (designated ‘critical
habitats’). There is a lot of criticism on these instruments in the US; especially
the effectiveness of designating critical habitats is disputed.

THE GEOGRAPHY OF ECOSYSTEM SERVICES: MAXIMIZING THE VALUE OF LANDSCAPES IN LAND USE
CONSERVATION
This paper draws on recent theoretical and methodological developments in the economic
valuation of ecosystem services and spatial analysis to discuss a new approach for
assessing the value of ecosystem services at multiple spatial scales. The services
provided by ecological systems are critical to the healthy functioning of the natural
environment; but they also contribute significantly to human welfare, both directly
and indirectly, and thus represent a significant portion of the total economic value
of natural landscapes. When ecosystem service values are not fully accounted for,
they remain outside the calculus of land use planning, thereby compromising the long-term
sustainability of ecologically significant landscapes. Better accounting of ecosystem
service values will help scientists, decision-makers, and land use planners evaluate
trade-offs among the many different management options they will face as natural
landscapes increasingly come under pressure by humans. We discuss our development
of a flexible, web-based spatial decision support system that allows end-users to
conduct value assessments of selected landscape features at multiple spatial scales
in a fully interactive, ‘data transparent’ environment. The result is a spatial decision
support system capable of generating reliable value estimates of landscapes that
can be integrated into land use planning at multiple spatial scales.

NATURE CONSERVATION AND TOURISM IN THE AEGEAN ISLANDS
Tourism has provided many small islands in the Aegean with substantial opportunities
for income and employment. In some cases these have led to a reversal of past trends
of population decline and abandonment. Opportunities are not evenly distributed as
a variety of factors affect the spatial patterns of growth and development. Tourism
is accounting for much change in local societies and environmental quality. Change
might be interpreted in a positive manner but may also incorporate serious negative
impacts. As islands are closed systems with intensive interdependence of society-economy
and environment, impacts in one sector affect the entire system. Environmental change
is particularly important as it affects ultimately the tourist activity itself. With
a broader perspective on environmental quality, incorporating quality of life dimensions,
tourism relates directly to quality of life in tourist destinations. Most islands
in the Aegean are seeking sustainable development policies, particularly in relation
to tourism. As the interpretation of sustainable tourism varies from one place to
another so do policy responses. Seeking sustainable tourism policies is often based
on several key assumptions regarding the capacity, often limited, of local societies
to control tourist development while safeguarding their natural and cultural heritage.

THE FOUNDATIONS OF POLAND’S CULTURAL LANDSCAPE PROTECTION — CONSERVATION POLITICS
From the very moment of the origin of life on earth the natural resources of our
planet have evolved through the successional natural processes modified by climatic
changes and distributed by various catastrophes such as orogenic movements, floods
or fires. The appearance of man has brought about disturbances and modifications
of natural processes. Natural resources varying in different spots of our globe influenced
the awareness of sociates which was reflected in the broadly undrstood cultural resources.
The three components: society, natural resources and cultural resources are inseperable,
forming a cultural landscape. The changes in the social and economic system in Poland
the late 1980s and the early 1990s and the respective development of local governments
which should favour the protection of cultural landscape on the contrary they seem
to be a serious threat to the landscape. The only way to counteract the threat is
to promote and implement the policy of sustainable development However, it requires
highly qualified staff who might hold responsible positions in the state and local
administration. The staff who can evaluate and assess the value of the cultural landscape
and is able to include this value in economic analyses of all investments promoting
regional development.

THE FILSALB PROJECT: COMMUNITIES AS MEDIATORS - THE USEFULNESS OF ACCEPTANCE IN NATURE
CONSERVATION
Communities represent the political scale at which humans actually shape and administer
their environment. Decisions whether ideas and concepts remain abstract theory or
will be implemented are mostly made at the communal level. Here, the interests of
land-use and conservation meet or sometimes clash and have to be balanced. Nature
conservation has to overcome barriers of acceptance within communities, if it is
not to just be an obligation imposed from higher political and administrative levels.
Nature conservation can not be sustained against the interests of the majority of
those directly affected by measures. Within the context of the 'Filsalb'-Project,
communities attempt to seek more acceptance for nature conservation and at the same
time to grant a just and thus sustainable balance of interests. In an area characterised
by species-rich chalk grassland the project attempts to integrate concerns from nature
conservation, agriculture and recreation/tourism into measures that provide benefits
for all the parties involved. Measures include improved funding for extensive land-use,
marketing of locally grown produce, visitor guidance and information linking land-use
to landscape qualities. The project seeks acceptance for conservation targets by
generating win-win-situations rather than acceptance through scientific or pseudo-scientific
discourse.
