BASIC CONCEPTS IN GEOCONSERVATION

ALEXANDRU ANDRASANU

ABSTRACT Geoconservation evolved very rapidly in the last decade and now its basic concepts, structure, tools and activities are well defined. Main areas of activity are focused around few basic concepts like: geodiversity, geological heritage, geotopes / geosites, geopark, geoeducation. The potential for interaction between natural conservation and socio-economic activities made geoconservation a new area of applied geology aiming to assure a sustainable use of natural resources for sustainable development and requiring a new type of specialist: geoconservationist.

REZUMAT Geoconservarea a evoluat foarte rapid in ultima decada, reusind sa-si defineasca metodele de activitate, conceptele de baza si instrumentele de lucru, putind fi considerata un domeniu nou in geologia aplicata. Geoconservarea integreaza intr-un mod logic si coerent concepte precum geodiversitate, patrimoniu geologic, geoturism, geoparc, geoeducatie si le aplica intr-un cadru mai larg al conservarii naturii si dezvoltarii durabile, cu efecte positive in viata sociala si economica. Geoconservarea este un domeniu interdisciplinar, ce combina elementele de geologie cu cele de biologie, sociologie, amenajarea teritoriului, dezvoltare rurala, educatie, necesitind astfel o noua specializare: geoconservationistul. Key words: geoconservation, geodiversity, geological heritage, geopark, geoeducation, sustainable development

INTRODUCTION Most part of the activities dealing with nature conservation is focused on living things, the so called biodiversity. Geoconservation deals with the conservation of non-living parts of the natural environment like geological features, landforms and soils. These non-living parts of the natural environment have significant values, and many aspects of this geodiversity are just as sensitive to disturbance as biodiversity.

Geoconservation could be considered for a long period of time the forgotten half of the nature conservation (Sharples, 2002). Moreover, biodiversity is dependant upon geodiversity, so that successful nature conservation requires the integration of geoconservation with bioconservation.

Since the Rio Conference it is recognized that if the Earths environment is to be respected, a better understanding of the geological, biological and physical processes that have left their mark on the Earths surface is required. A good knowledge of geological heritage and a healthy respect for what it represents is an important factor in the holistic approach for sustainable development. In this broader approach this paper intended to provide a brief introduction to the issues of geoconservation and its basic concepts: geodiversity, geological heritage, geotourism, geoparks and geoeducation, based on personal experience and projects developed during the last fifteen years.

GEOCONSERVATION

1. Defining geoconservation Geoconservation is continuing an early work based mostly on recognition of the scientific and research values of certain bedrock features as heritage which informs us about the Earth's past development, resulted in the preparation of inventories of significant bedrock sites and some landform features. During the last decade geoconservation activities were better integrated in physical planning and development strategies their social and economic impact being more and more taken into consideration.

Continuing the classical approach geoconservation can be defined (Sharples, 2002) as the conservation of the diversity of geological, geomorphological and soil features, assemblages, systems and processes. In that case geoconservation is an approach to the conservation management of rocks, landforms and soils which recognizes that geodiversity has nature conservation values. Considering nature conservation to necessarily comprise both geoconservation and bioconservation provides a more holistic approach to nature conservation. Geoconservation seeks to prevent or minimize degradation in order to protect the natural and intrinsic values of bedrock, landforms and soils, rather than only to maintain their usefulness or utilitarian value to humans (Grigorescu, 1990). This approach is distinct from other earth science - based approaches to land management such as soil conservation, environmental geology and geomorphic hazards management, which are essentially focused on utilitarian or anthropocentric values. A broader view consider that geoconservation is more than protection and conservation of the non living things for their intrinsic or aesthetic value which is rather a static or defensive position against economical use of natural resources or landscape degradation due to human activities.

According to this vision geoconservation is a new and developing area of applied geology aiming to assure a holistic approach of nature conservation and to offer new tools in sustainable use of natural resources for social and economic development. Geoconservation can contribute to the objectives of Agenda 21, highlighting the potential for interaction between socio-economic development and conservation of the natural environment. This approach allows considering other issues like geodiversity, geological heritage, geotourism, geoparks and geoeducation as concepts of geoconservation (see Figure 1).

The aim of geoconservation is to identify the ways that geodiversity can be managed, to outline the need for more holistic approach to nature conservation and land management and to integrate geodiversity in sustainable development plans for different areas.

2. Geodiversity Geodiversity comprises the variety of rocks, fossils, minerals, landforms and soils, tectonic and hydrogeologic features that occurs on our planet, along with the natural processes that shape the landscape. Geodiversity also forms an intrinsic component of the environment in which we live, shaping our landscape, providing locally distinctive building materials for our towns and cities, providing a recreational resource, and influencing the type and distribution of wildlife habitats.

Geodiversity could be regarded also as analogous to the term 'biodiversity', which bioconservationists use to highlight the importance of conserving biological genetic, species and community diversity. Criticisms of this analogy (Murrey, 2004) are related to the difference in the amount of time commonly involved in the evolution of the two, the difference between an active ecosystem involving living organisms and the non living processes of the landscape or rocks,

differences from the conceptual point of view, biodiversity being based on biological and ecological theory involving different taxonomic ranks and their active interrelationship opposite to geodiversity regarded as a sum of different geological issues occurred after a long geological evolution of one area. From the conceptual point of view the two are not identical but is generally recognised that geodiversity influences biodiversity and is its life-support system, between the two being an inextricable link. As biologists tried to measure biodiversity is it possible to define a geodiversity index based on geological features of one area (type of rocks, percent of surface occupied by each type, rock age index and tectonic characteristics) and the relationship with climatic conditions and landforms.

The importance of the term geodiversity is that it underlines the idea of interdependence of geological features and social and cultural evolution in one area. Different approaches have tried to outline the cultural or heritage value, the economic value and the research and educational value of geodiversity. In this case one of the fundamental aims of geoconservation should be to identify, inventory and integrate these suites of features and processes in local development strategies and plans. Geodiversity Action Plans, developed in United Kingdom are good examples of activities aiming: to inventory the geotopes in one area, to raise awareness of the fundamental importance of geodiversity in the sustainable management, to identify linkages between the areas geodiversity and its landscape character, biodiversity, economic and cultural history, to identify features and topics which can contribute to sustainable geotourism, to engage industry, local communities, voluntary groups and local societies in conserving and interpreting the areas geodiversity and to embed geodiversity into future planning, management and interpretation policies.

3. Geological heritage Geological heritage (geoheritage) is the valuable part of the geodiversity as we consider from different subjective and objective reasons with close relation to the interpretations of geophenomena that have influentially informed the development of geology and geography from at least the sixteenth century onwards. However, both landforms and geophenomena often have older mythological, religious and more recent aesthetic significance (Hose, 2005). These scientific and cultural elements when combined create a major World Heritage. European archives, libraries, museums and universities are a storehouse of global significance for that geoheritage both specimens and documentation. However, this geoheritage and its value is frequently neglected and threatened. A tangible and accessible form of the geological heritage is the geotope or geosite or geological monument that could be considered in some ways similar designations of the same concept. Geotopes or geosites are bodies of rocks or areas, accessible from surface, where geological or geomorphologic features and phenomena interesting from scientifically, educational or aesthetic point of view are well preserved or present, and can be observed and studied. Usually no single geological feature or phenomena can be observed but one or few are

more important. Geotopes protection includes all kinds of measures of preservation, development and management in their natural diversity and characteristics and is a part of the geoconservation activity and land use planning (Grigorescu & Andrasanu, 1997)

4. Geotourism Geotourism is an economical approach in geoconservation developed during the last decades due to the lack of other financial resources in the effort of protection and promotion of the geological heritage (Martini, 2000). Geotourism is both a geoconservation and sustainable exploitation strategy. Its success depends upon attracting and maintaining the support of politicians, planners and developers by demonstrating the geoheritages potential for the tourism and outdoor recreation industries (Hose, 2005). In general, and ideally, any sort of tourism should strive to be 'sustainable'. And must be for example ecologically bearable in the long term, must contribute positively to local economic development (creation of local employment), mutually involve and respect all actors both public and private (co-operation). On this basis, sustainable geotouristic development can practically result in certain advantages: creation of new products with geological connotation, sale of local products, and creation of new jobs linked to geology, guides, technicians, cottage industry, and support local development.

Geotourism is closely related to geoparks activities and sometimes other protected areas, often in combination with educational activities as an appropriate form of local economic development and an increasingly important source of income for the local communities. Geotourism is a type of tourism linked with for example eco-tourism, agro-tourism and nature and wildlife experience.

5. Geoparks The process of conception of geoparks started in 1997, and resulting from a European Leader program among 4 territories, focused on their geological heritage, Geoparks appear in Europe in 2000 and at the world level, by UNESCOs initiative, in 2004.

A Geopark is a territory that has clearly defined boundaries, that encompasses a specific geological heritage and designs a sustainable development territorial strategy. The majority of sites present on the territory of a Geopark must be part of the geological heritage, but their interest may also be archaeological, ecological, historical or cultural. A Geopark represent a patrimonial appreciation which results from interdisciplinary approach of mixed teams: specialists on development and specialists on geological heritage. The territory of the geopark has to be coherent from the social, administrative and cultural point of view and a management plan able to assist and foster socio-economic development that is culturally and environmentally sustainable has to be set up. A Geopark provides a close cooperation between institutions and persons, both from the public and private sectors, and from governmental and nongovernmental organizations. A close

involvement of the universities with their staff and students plays an essential role in planning and developing the complex activities in education, training, local planning, and nature conservation (Andrasanu, 2005).

The success of the approach in geopark concept development and its economic and social benefits leaded to the creation of the European Geoparks Network and of the Global UNESCO Geoparks Network. A network member develops experiments with and enhances methods for preserving the geological heritage. It works with local enterprises to promote and support the creation of new by-products linked with the geological heritage in a complimentary spirit with the other members.

Despite these excellent results there are criticisms in the geopark development. These territories became more and more similar to Biosphere Reserves or Natural Regional Parks and are using the old fashion methodology in tourist interpretation. Geoparks have to be innovative territories able to develop new and revolutionary strategies in nature conservation approach and reappropriate Man and Earth. A new approach of advance was recommended: the geopark phase II (Martini, 2006).

6. Geoeducation Is well known education, formal or informal, is a strong tool and therefore a big priority for successful geoconservation activities and promotion of geosciences. Geoeducation is part of the conservation purposes of geological heritage sites that worth preservation for scientific, educational and aesthetic reasons. Inventory, databases and maps of sites are not enough for their conservation. Educational strategy is necessary to be set-up in partnership with schools, universities, and local councils, in order to develop training packages and courses for local teaching staff and students, to organize events for public awareness in natural and cultural heritage. Geoeducation has to develop its own structure and educational tools based on results of scientific research. It has to be considered in broader frame as part of education for nature conservation and ultimately an important part of education for sustainable development.

CONCLUSIONS Geoconservation evolved in the last decade and now its basic concepts, structure, tools and activities are well defined. Main areas of activity are focused around few basic concepts, some of them already known for a long time but now reorganized and integrated into a logical and coherent framework. These concepts are: geodiversity, geological heritage, geotourism, geopark, geoeducation

The potential for interaction between natural conservation and socio-economic activities made geoconservation a new and developing area of applied geology aiming to assure a sustainable use of natural resources for sustainable development and requiring a new type of specialist: geoconservationist.
