8 SYNTHESIS vii SYNTHESIS CCONTTEEXXTT AND ORI IIGI IIN OFF TTHEE CCONCCEEPTT OFF LLONG TTEERM EECCOLLOGI IICCALL MONI IITTORI IING Following the intense and recurrent droughts that had prevailed in sub-saharan Africa in the mid- 1960s, political awareness and the mobilisation of the scientific community toward checking the desertification processes and mitigating drought effects have brought about the need to monitor and evaluate the natural resources in order to ensure their sustainable management. This has led to conducting several studies and research works on droughts and aridity, as well as on their ecological implications (soil degradation, desertification) and socio-economic impacts (migration, rural exodus, pauperisation). This period was characterised by the adoption of the action plan to combat desertification which was developed during the United Nations Conference on Desertification (Nairobi, Kenya, August/September 1977) and the coming into force of the United Nations Convention to Combat Desertification (CCD). This convention a strategy in its own right strongly emphasises the development of scientific and technical cooperation among the relevant institutions at national, subregional, regional and international level. In this regard, the establishment of the Sahara and Sahel Observatory (OSS) in 1992, has favoured the emergence of a new North-South-South partnership and solidarity spirit, as well as the development of new synergies between the various partners, thus allowing the capitalisation of acquired knowledge and experience, the harmonisation of data collection and analysis methods, information sharing and the design of new tools to help in decision making. In view of these considerations, and based on the conclusions and recommendations of a workshop organised jointly with UNESCO and the International Geosphere-Biosphere Programme (IGBP) in July 1992 in Fontainebleau (France) on continuous monitoring of terrestrial ecosystems, OSS proposed the set up of a Long Term Ecological Monitoring Observatories Network (ROSELT/OSS) whose objective would be to better apprehend the causes and effects of desertification in the circum-saharan African region. This initiative constitutes a response to the need expressed by the Southern member countries to access reliable data on the state of the environment, and more particularly in circum-saharan arid and semi-arid zones that are severely hit and/or endangered by desertification. Ecological monitoring is understood in its broadest sense, namely the study of the dynamics of the natural, physical and biological environment, of the human environment, including social organisation, the dynamics of land use systems, as well as the dynamics of the interactions that exist between these various sets. FFROM DEESI IIGN TTO AN OP EERA TT IIONA I LL IIMPLLEEMEENTTATTI I IION OFF TTHEE ROSEELLTT/ /OSS PROGRAMMEE Between 1992 and 1994, the inventory of Potential Candidate Territories (TCP) which had been conducted by the countries allowed an ad hoc Scientific Committee to select, based on labellisation criteria, 25 observatories or observatory clusters, distributed over 11 countries. Among these 25 ROSELT/OSS observatories, 12 were further selected as pilotobservatories, intended to serve within a first phase as a basis for refining the concept, finalising the techniques and methodologies of data collection and processing, and developing reliable, relevant and reproducible tools to help in decision-making (maps, indicators, information systems...).
9 SYNTHESIS viii In the light of these works, the founding document of the ROSELT/OSS was drafted in 1995 and synthesis studies providing «a reference state» in three North-African pilot-observatories ( ) were conducted. A first operational phase was subsequently launched in 1998 in order to perform in situ testing of the data collection and processing methods. The insufficient integration between the devices used for the sampling of biophysical and socio-economic parameters based on the sectorial approach adopted during this phase did not allow the development of the expected tools to help in decision making. The launch of the ROSELT/OSS in West Africa in June 2000 during the Bamako workshop led to updating the concepts used within the network and to adopting a comprehensive conceptual outline for the study of environmental changes within the ROSELT/OSS. The «landscape» thus developed allows the integration of the whole set of biophysical and socioeconomic data and the study of the impact of uses on the natural resources, and this with a view to developing products that help in decision making, such as reliable data on soil degradation in arid zones, biophysical and socio-economic indicators, state of the environment of the OSS region, spatialised resources/uses balances, prospective scenarios... Particular effort was made in order to define a minimum data set, to be collected at lower cost, and which would allow the spatialisation of data, their possible extrapolation to larger zones and their integration within models of use of both space and resources.

10 SYNTHESIS ix The relevance of the concept of ecological monitoring and of the products developed by the network have persuaded a large number of the countries involved in the network as to the need to boost the development of environmental monitoring on the level of the countries. Indeed, the ROSELT/OSS has already been integrated in the NAP/CCD of several countries (Algeria, Mali, Morocco, Niger, Tunisia) and is in process of integration in the NAP/CCD of Egypt and of Kenya. The ROSELT/OSS methodologies are adapted and replicated in the framework of implementation of the national environmental monitoring devices (Niger, Mali) which are either based on, or which integrate, environmental monitoring observatories, such as the ROSELT/OSS observatories. Besides, Morocco and Tunisia 1 have undertaken to conduct two studies in order to assess the state of the art in the field of monitoring-evaluation of desertification (research projects, development projects...) and to use the results acquired for purposes of proposing an overall framework for an operational implementation of the NAP/CCD monitoring-evaluation systems. The substantial contribution of the ROSELT/OSS has been largely underscored, particularly with regard to control over the desertification process and to the promotion of development support actions. The results already obtained by the ROSELT/OSS in Tunisia (indicators, prospective simulations deriving from the LEIS- ROSELT/OSS and desertification risk index map) will be gradually displayed on the Tunisian site of the System of Information Sharing on Desertification and the Environment (SCIDE, updated in the framework of the SMAP project). More specific studies on the national environmental monitoring devices have been conducted in Algeria 2, Egypt 3 and Morocco 4 ; they are in process of validation by the National Coordination Institutions (ONC) in these countries. It is worth pointing out that the data and metadata bases in process of establishment in each of the member countries of the network represent a major asset for the countries in the field of management and dissemination of data that help in decision making. Finally, the whole set of the products developed and of the results obtained are regularly presented during international events (colloquia, seminars... ) and on the occasion of the Conferences of the Parties to the United Nations Convention to Combat Desertification (UNCCD). The information dissemination tools (web sites, brochures, posters...) are regularly updated in order to provide updated information to the various categories of stakeholders concerned by combating desertification. ROSEELLTT/ /OSS : AN ASSEETT FFOR TTHEE SEETT UP OFF NATTI IIONALL EENVVI IIRONMEENTTALL MONI IITTORI IING DEEVVI IICCEES The ROSELT/OSS programme is a complex, ambitious and exacting programme. It is complex, since it sets out to study not only the state of the dynamics of the ecological and socio-economic systems and their interactions, but also the causes and consequences of soil degradation. It is ambitious, since it seeks to bring concrete and practical answers to issues of development and of environmental protection in areas where the scarce resources are vulnerable. And it is exacting, since it requires several scientific specialities, team work within multi-disciplinary and inter-disciplinary teams, calling upon the contribution of the whole range of the stakeholders involved in combating desertification (planners, developers and development officials in general, including the populations concerned), and this within the framework of a participatory approach. Yet the ROSELT/OSS remains for all that an absolutely necessary programme to address the concern for monitoring and evaluation of the phenomena of degradation and, where necessary, to provide the countries with reliable and relevant data that can be generalised and/or extrapolated, and which are generated by the close interdependence between environment and sustainable development. To address this concern, only the set up of long term ecological monitoring devices would help to provide an answer. 1 On the occasion of the launch workshops of the SMAP project for «Setting up a monitoring-evaluation system in the Maghreb» held in Rabat (on 28 and 29 November 2002) and in Tunis (on 22 and 23 April 2003). 2 Les mécanismes de suivi de la désertification en Algérie.

11 SYNTHESIS x However, while the long term vision of land use planning and the management of resources represents an attractive conceptual framework, its implementation needs to overcome several obstacles which the ROSELT/OSS has not been spared. Indeed, ecological monitoring requires fairly considerable human and material means, as well as stable and sound institutions. However, such conditions are often difficult to find in developing countries, particularly in Africa. The lack of synergy between the national institutions has often proved to be an impediment to a proper progress of the programme and has induced, at its inception, a slackening of the pace of the implementation of its activities. Much effort had to be invested in order to get the message across to the institutions concerned that the OSS is not a funding agency and that the means that they provide need, on the one hand, to incept a national effort in this regard and, on the other hand, to build up the teams and the institutions involved. The implementation of this unusual approach has been arduous, resulting in certain cases in delays due to the insufficiency of the means provided in view of the efforts required. Yet, in spite of such handicaps, which seem a priori to be difficult to overcome, the ROSELT/OSS programme was launched and it became established in several OSS member countries. This inception phase has been, above all, a phase of training, set up of teams and finalisation from a conceptual and methodological point of view. The active work of the network, the exchanges between the members, not to forget the strengthening of the North-South partnership and the building of national capacities have made it possible to extend, to the countries of the South, the methodological and technological developments indispensable for a mastery over the dissemination of information that help in decision making. Concrete results have thus been achieved in the past 4 years. The tools (data and metadata bases, Local Environment Information Systems (LEIS) and products developed by the network already contribute in : o the harmonisation of the data collection and processing methods (methodological guidebooks) ; o the development of a diagnosis of the state of desertification in the circum-saharan zones of the OSS region ; o the definition of a specific minimum data set for each «observatory» and the minimum set of data common to the «network» which need to be collected at lower cost with a view to developing specific and necessary indicators on the local and regional levels. The dynamics that has developed within the network, the appropriation of the ROSELT/OSS methodologies and of long term environmental monitoring by the national institutions, the drafting of a charter on the management and dissemination of data within the network, and the gradual implementation of computer tools constitute a major step toward the strengthening of the network and its integration within the national environmental monitoring devices. The ROSELT/OSS programme constitutes an additional asset for African countries and for the subregional and regional institutions in combating desertification and in mitigating drought effects, and in particular as a key component of the national environmental monitoring devices, which themselves constitute the major pillars of the monitoring-evaluation of the NAP/CCD. 5 Accordingly, the OSS does not spare any effort to clarify and further the debate on the concept of monitoring evaluation and to make visible the contribution of the ROSELT/OSS in the implementation of development and environmental protection programmes. The products that help in decision making which are gradually developed in the framework of the ROSELT/OSS programme will be made available to the NAP/CCD Monitoring-Evaluation Systems that are gradually set up, particularly in Tunisia and in Morocco, in the context of the implementation of the conventions on combating desertification and on biological diversity. On the international and European level, the ROSELT/OSS now emerges as an indispensable African network in the field of ecological monitoring. The North-South scientific rooting of the network has been considerably strengthened, particularly thanks to the set up of a ROSELT/OSS specific «Desertification» Service Unit within the Research Institute for Development (IRD, formerly ORSTOM) 5 Such as recommended by the CCD, and designed by the OSS and its partners : The CILSS, UMA and 7 African pilot countries, which have been joined by GRULAC and China in the framework of a working group that was set up following a recommendation by the CoP4.
12 SYNTHESIS xi and to the involvement of the ROSELT/OSS programme in the draft applications eligible to the European Commission. These initiatives are likely to promote scientific cooperation on desertification among the specialised institutions from both North and South and will help toward the sustainability of the network and the mobilisation of the means allotted to this complex issue.
