SCIENCE FOR SUSTAINABLE DEVELOPMENT

INTRODUCTION

35.1. This chapter focuses on the role and the use of the sciences in supporting the prudent management of the environment and development for the daily

survival and future development of humanity. The programme areas proposed herein are intended to be over-arching, in order to support the specific scientific

requirements identified in the other Agenda 21 chapters. One role of the sciences should be to provide information to better enable formulation and selection of

environment and development policies in the decision-making process. In order to fulfil this requirement, it will be essential to enhance scientific understanding,

improve long-term scientific assessments, strengthen scientific capacities in all countries and ensure that the sciences are responsive to emerging needs.

35.2. Scientists are improving their understanding in areas such as climatic change, growth in rates of resource consumption, demographic trends, and

environmental degradation. Changes in those and other areas need to be taken into account in working out long-term strategies for development. A first step

towards improving the scientific basis for these strategies is a better understanding of land, oceans, atmosphere and their interlocking water, nutrient and

biogeochemical cycles and energy flows which all form part of the Earth system. This is essential if a more accurate estimate is to be provided of the carrying

capacity of the planet Earth and of its resilience under the many stresses placed upon it by human activities. The sciences can provide this understanding

through increased research into the underlying ecological processes and through the application of modern, effective and efficient tools that are now available,

such as remote-sensing devices, robotic monitoring instruments and computing and modelling capabilities. The sciences are playing an important role in linking

the fundamental significance of the Earth system as life support to appropriate strategies for development which build on its continued functioning. The

sciences should continue to play an increasing role in providing for an improvement in the efficiency of resource utilization and in finding new development

practices, resources, and alternatives. There is a need for the sciences constantly to reassess and promote less intensive trends in resource utilization, including

less intensive utilization of energy in industry, agriculture, and transportation. Thus, the sciences are increasingly being understood as an essential component

in the search for feasible pathways towards sustainable development.

35.3. Scientific knowledge should be applied to articulate and support the goals of sustainable development, through scientific assessments of current

conditions and future prospects for the Earth system. Such assessments, based on existing and emerging innovations within the sciences, should be used in the

decision-making process and in the interactive processes between the sciences and policy-making. There needs to be an increased output from the sciences in

order to enhance understanding and facilitate interaction between science and society. An increase in the scientific capacity and capability to achieve these goals

will also be required, particularly in developing countries. Of crucial importance is the need for scientists in developing countries to participate fully in

international scientific research programmes dealing with the global problems of environment and development so as to allow all countries to participate on

equal footing in negotiations on global environmental and developmental issues. In the face of threats of irreversible environmental damage, lack of full scientific

understanding should not be an excuse for postponing actions which are justified in their own right. The precautionary approach could provide a basis for

policies relating to complex systems that are not yet fully understood and whose consequences of disturbances cannot yet be predicted.

35.4. The programme areas, which are in harmony with the conclusions and recommendations of the International Conference on an Agenda of Science for

Environment and Development into the 21st Century (ASCEND/21) are:

(a) Strengthening the scientific basis for sustainable management;

(b) Enhancing scientific understanding;

(c) Improving long-term scientific assessment;

(d) Building up scientific capacity and capability.

PROGRAMME AREAS

A. Strengthening the scientific basis for sustainable management

Basis for action

35.5. Sustainable development requires taking longer-term perspectives, integrating local and regional effects of global change into the development process, and

using the best scientific and traditional knowledge available. The development process should be constantly re-evaluated, in light of the findings of scientific

research, to ensure that resource utilization has reduced impacts on the Earth system. Even so, the future is uncertain, and there will be surprises. Good

environmental and developmental management policies must therefore be scientifically robust, seeking to keep open a range of options to ensure flexibility of

response. The precautionary approach is important. Often, there is a communication gap among scientists, policy makers, and the public at large, whose

interests are articulated by both governmental and non-governmental organizations. Better communication is required among scientists, decision makers, and

the general public.

Objectives

35.6. The primary objective is for each country with the support of international organizations, as requested, to identify the state of its scientific knowledge

and its research needs and priorities in order to achieve, as soon as possible, substantial improvements in:

(a) Large-scale widening of the scientific base and strengthening of scientific and research capacities and capabilities/- in particular, those of developing

countries/- in areas relevant to environment and development;

(b) Environmental and developmental policy formulation, building upon the best scientific knowledge and assessments, and taking into account the need to

enhance international cooperation and the relative uncertainties of the various processes and options involved;

(c) The interaction between the sciences and decision-making, using the precautionary approach, where appropriate, to change the existing patterns of

production and consumption and to gain time for reducing uncertainty with respect to the selection of policy options;

(d) The generation and application of knowledge, especially indigenous and local knowledge, to the capacities of different environments and cultures, to achieve

sustained levels of development, taking into account interrelations at the national, regional and international levels;

(e) Improving cooperation between scientists by promoting interdisciplinary research programmes and activities;

(f) Participation of people in setting priorities and in decision-making relating to sustainable development.

Activities

35.7. Countries, with the assistance of international organizations, where required, should:

(a) Prepare an inventory of their natural and social science data holdings relevant to the promotion of sustainable development;

(b) Identify their research needs and priorities in the context of international research efforts;

(c) Strengthen and design appropriate institutional mechanisms at the highest appropriate local, national, subregional and regional levels and within the United

Nations system for developing a stronger scientific basis for the improvement of environmental and developmental policy formulation consistent with

long-term goals of sustainable development. Current research in this area should be broadened to include more involvement of the public in establishing

long-term societal goals for formulating the sustainable development scenarios;

(d) Develop, apply and institute the necessary tools for sustainable development, with regard to:

(i) Quality-of-life indicators covering, for example, health, education, social welfare, state of the environment, and the economy;

(ii) Economic approaches to environmentally sound development and new and improved incentive structures for better resource management;

(iii) Long-term environmental policy formulation, risk management and environmentally sound technology assessment;

(e) Collect, analyse and integrate data on the linkages between the state of ecosystems and the health of human communities in order to improve knowledge of

the cost and benefit of different development policies and strategies in relation to health and the environment, particularly in developing countries;

(f) Conduct scientific studies of national and regional pathways to sustainable development, using comparable and complementary methodologies. Such

studies, coordinated by an international science effort, should to a large extent involve local expertise and be conducted by multidisciplinary teams from

regional networks and/or research centres, as appropriate and according to national capacities and the available resources;

(g) Improve capabilities for determining scientific research priorities at the national, regional and global levels to meet the needs of sustainable development.

This is a process that involves scientific judgements regarding short-term and long-term benefits and possible long-term costs and risks. It should be adaptive

and responsive to perceived needs and be carried out via transparent, "user-friendly", risk-evaluation methodologies;

(h) Develop methods to link the findings of the established sciences with the indigenous knowledge of different cultures. The methods should be tested using

pilot studies. They should be developed at the local level and should concentrate on the links between the traditional knowledge of indigenous groups and

corresponding, current "advanced science", with particular focus on disseminating and applying the results to environmental protection and sustainable

development.

Means of implementation

(a) Financing and cost evaluation

35.8. The Conference secretariat has estimated the average total annual cost (1993-2000) of implementing the activities of this programme to be about $150

million, including about $30 million from the international community on grant or concessional terms. These are indicative and order of magnitude estimates

only and have not been reviewed by Governments. Actual costs and financial terms, including any that are non-concessional, will depend upon, inter alia, the

specific strategies and programmes Governments decide upon for implementation.

(b) Scientific and technological means

35.9. The scientific and technological means include the following:

(a) Supporting new scientific research programmes, including their socio-economic and human aspects, at the community, national, subregional, regional and

global levels, to complement and encourage synergies between traditional and conventional scientific knowledge and practices and strengthening

interdisciplinary research related to environmental degradation and rehabilitation;

(b) Setting up demonstration models of different types (e.g., socio-economic, environmental conditions) to study methodologies and formulate guidelines;

(c) Supporting research by developing relative-risk evaluation methods to assist policy makers in ranking scientific research priorities.

B. Enhancing scientific understanding

Basis for action

35.10. In order to promote sustainable development, more extensive knowledge is required of the Earth's carrying capacity, including the processes that could

either impair or enhance its ability to support life. The global environment is changing more rapidly than at any time in recent centuries; as a result, surprises

may be expected, and the next century could see significant environmental changes. At the same time, the human consumption of energy, water and

non-renewable resources is increasing, on both a total and a per/capita basis, and shortages may ensue in many parts of the world even if environmental

conditions were to remain unchanged. Social processes are subject to multiple variations across time and space, regions and culture. They both affect and are

influenced by changing environmental conditions. Human factors are key driving forces in these intricate sets of relationships and exert their influence directly

on global change. Therefore, study of the human dimensions of the causes and consequences of environmental change and of more sustainable development

paths is essential.

Objectives

35.11. One key objective is to improve and increase the fundamental understanding of the linkages between human and natural environmental systems and

improve the analytical and predictive tools required to better understand the environmental impacts of development options by:

(a) Carrying out research programmes in order better to understand the carrying capacity of the Earth as conditioned by its natural systems, such as the

biogeochemical cycles, the atmosphere/hydrosphere/lithosphere/cryosphere system, the biosphere and biodiversity, the agro-ecosystem and other terrestrial

and aquatic ecosystems;

(b) Developing and applying new analytical and predictive tools in order to assess more accurately the ways in which the Earth's natural systems are being

increasingly influenced by human actions, both deliberate and inadvertent, and demographic trends, and the impact and consequences of those actions and

trends;

(c) Integrating physical, economic and social sciences in order better to understand the impacts of economic and social behaviour on the environment and of

environmental degradation on local and global economies.

Activities

35.12. The following activities should be undertaken:

(a) Support development of an expanded monitoring network to describe cycles (for example, global, biogeochemical and hydrological cycles) and test

hypotheses regarding their behaviour, and improve research into the interactions among the various global cycles and their consequences at national,

subregional, regional and global levels as guides to tolerance and vulnerability;

(b) Support national, subregional, regional and international observation and research programmes in global atmospheric chemistry and the sources and sinks of

greenhouse gases, and ensure that the results are presented in a publicly accessible and understandable form;

(c) Support national, subregional, regional and international research programmes on marine and terrestrial systems, strengthen global terrestrial databases of

their components, expand corresponding systems for monitoring their changing states and enhance predictive modelling of the Earth system and its

subsystems, including modelling of the functioning of these systems assuming different intensities of human impact. The research programmes should include

the programmes mentioned in other Agenda 21 chapters which support mechanisms for cooperation and coherence of research programmes on global change;

(d) Encourage coordination of satellite missions, the networks, systems and procedures for processing and disseminating their data; and develop the interface

with the research users of Earth observation data and with the United Nations EARTHWATCH system;

(e) Develop the capacity for predicting the responses of terrestrial, freshwater, coastal and marine ecosystems and biodiversity to short- and long-term

perturbations of the environment, and develop further restoration ecology;

(f) Study the role of biodiversity and the loss of species in the functioning of ecosystems and the global life-support system;

(g) Initiate a global observing system of parameters needed for the rational management of coastal and mountain zones and significantly expand freshwater

quantity/quality monitoring systems, particularly in developing countries;

(h) In order to understand the Earth as a system, develop Earth observation systems from space which will provide integrated, continuous and long-term

measurements of the interactions of the atmosphere, hydrosphere and lithosphere, and develop a distribution system for data which will facilitate the

utilization of data obtained through observation;

(i) Develop and apply systems and technology that automatically collect, record and transmit data and information to data and analysis centres, in order to

monitor marine, terrestrial and atmospheric processes and provide advance warning of natural disasters;

(j) Enhance the contribution of the engineering sciences to multidisciplinary research programmes on the Earth system, in particular with regard to increasing

emergency preparedness and reducing the negative effects of major natural disasters;

(k) Intensify research to integrate the physical, economic and social sciences to better understand the impacts of economic and social behaviour on the

environment and of environmental degradation on local and global economies and, in particular:

(i) Develop research on human attitudes and behaviour as driving forces central to an understanding of the causes and consequences of environmental change

and resource use;

(ii) Promote research on human, economic and social responses to global change;

(l) Support development of new user-friendly technologies and systems that facilitate the integration of multidisciplinary, physical, chemical, biological and

social/human processes which, in turn, provide information and knowledge for decision makers and the general public.

Means of implementation

(a) Financing and cost evaluation

35.13. The Conference secretariat has estimated the average total annual cost (1993- 2000) of implementing the activities of this programme to be about $2

billion, including about $1.5 billion from the international community on grant or concessional terms. These are indicative and order of magnitude estimates

only and have not been reviewed by Governments. Actual costs and financial terms, including any that are non- concessional, will depend upon, inter alia, the

specific strategies and programmes Governments decide upon for implementation.

(b) Scientific and technological means

35.14. The scientific and technological means include the following:

(a) Supporting and using the relevant national research activities of academia, research institutes and governmental and non-governmental organizations, and

promoting their active participation in regional and global programmes, particularly in developing countries;

(b) Increasing the use of appropriate enabling systems and technologies, such as supercomputers, space-based observational technology, Earth- and

ocean-based observational technologies, data management and database technologies and, in particular, developing and expanding the Global Climate Observing

System.

C. Improving long-term scientific assessment

Basis for action

35.15. Meeting scientific research needs in the environment/development field is only the first step in the support that the sciences can provide for the

sustainable development process. The knowledge acquired may then be used to provide scientific assessments (audits) of the current status and for a range of

possible future conditions. This implies that the biosphere must be maintained in a healthy state and that losses in biodiversity must be slowed down.

Although many of the long-term environmental changes that are likely to affect people and the biosphere are global in scale, key changes can often be made at

the national and local levels. At the same time, human activities at the local and regional levels often contribute to global threats/- e.g., stratospheric ozone

depletion. Thus scientific assessments and projections are required at the global, regional and local levels. Many countries and organizations already prepare

reports on the environment and development which review current conditions and indicate future trends. Regional and global assessments could make full use

of such reports but should be broader in scope and include the results of detailed studies of future conditions for a range of assumptions about possible future

human responses, using the best available models. Such assessments should be designed to map out manageable development pathways within the

environmental and socio-economic carrying capacity of each region. Full use should be made of traditional knowledge of the local environment.

Objectives

35.16. The primary objective is to provide assessments of the current status and trends in major developmental and environmental issues at the national,

subregional, regional and global levels on the basis of the best available scientific knowledge in order to develop alternative strategies, including indigenous

approaches, for the different scales of time and space required for long-term policy formulation.

Activities

35.17. The following activities should be undertaken:

(a) Coordinate existing data- and statistics-gathering systems relevant to developmental and environmental issues so as to support preparation of long-term

scientific assessments/- e.g., data on resource depletion, import/export flows, energy use, health impacts, demographic trends, etc.; apply the data obtained

through the activities identified in programme area B to environment/development assessments at the global, regional and local levels; and promote the wide

distribution of the assessments in a form that is responsive to public needs and can be widely understood;

(b) Develop a methodology to carry out national and regional audits and a five-year global audit on an integrated basis. The standardized audits should help to

refine the pattern and character of development, examining in particular the capacities of global and regional life-supporting systems to meet the needs of

human and non-human life forms and identifying areas and resources vulnerable to further degradation. This task would involve the integration of all relevant

sciences at the national, regional, and global levels, and would be organized by governmental agencies, non-governmental organizations, universities and research

institutions, assisted by international governmental and non-governmental organizations and United Nations bodies, when necessary and as appropriate. These

audits should then be made available to the general public.

Means of implementation

Financing and cost evaluation

35.18. The Conference secretariat has estimated the average total annual cost (1993- 2000) of implementing the activities of this programme to be about $35

million, including about $18 million from the international community on grant or concessional terms. These are indicative and order of magnitude estimates

only and have not been reviewed by Governments. Actual costs and financial terms, including any that are non-concessional, will depend upon, inter alia, the

specific strategies and programmes Governments decide upon for implementation.

35.19. With regard to the existing data requirements under programme area/A, support should be provided for national data collection and warning systems.

This would involve setting up database, information and reporting systems, including data assessment and information dissemination in each region.

D. Building up scientific capacity and capability

Basis for action

35.20. In view of the increasing role the sciences have to play in dealing with the issues of environment and development, it is necessary to build up scientific

capacity and strengthen such capacity in all countries/-particularly in developing countries/- to enable them to participate fully in the generation and

application of the results of scientific research and development concerning sustainable development. There are many ways to build up scientific and

technological capacity. Some of the most important of them are the following: education and training in science and technology; assistance to developing

countries to improve infrastructures for research and development which could enable scientists to work more productively; development of incentives to

encourage research and development; and greater utilization of their results in the productive sectors of the economy. Such capacity-building would also form

the basis for improving public awareness and understanding of the sciences. Special emphasis must be put on the need to assist developing countries to

strengthen their capacities to study their own resource bases and ecological systems and manage them better in order to meet national, regional and global

challenges. Furthermore, in view of the size and complexity of global environmental problems, a need for more specialists in several disciplines has become

evident world wide.

Objectives

35.21. The primary objective is to improve the scientific capacities of all countries/- in particular, those of developing countries/- with specific regard to:

(a) Education, training and facilities for local research and development and human resource development in basic scientific disciplines and in

environment-related sciences, utilizing where appropriate traditional and local knowledge of sustainability;

(b) A substantial increase by the year 2000 in the number of scientists/-particularly women scientists/- in those developing countries where their number is at

present insufficient;

(c) Reducing significantly the exodus of scientists from developing countries and encouraging those who have left to return;

(d) Improving access to relevant information for scientists and decision makers, with the aim of improving public awareness and participation in

decision-making;

(e) Involvement of scientists in national, regional and global environmental and developmental research programmes, including multidisciplinary research;

(f) Periodic academic update of scientists from developing countries in their respective fields of knowledge.

Activities

35.22. The following activities should be undertaken:

(a) Promote the education and training of scientists, not only in their disciplines but also in their ability to identify, manage and incorporate environmental

considerations into research and development projects; ensure that a sound base in natural systems, ecology and resource management is provided; and develop

specialists capable of working in interdisciplinary programmes related to environment and development, including the field of applied social sciences;

(b) Strengthen the scientific infrastructure in schools, universities and research institutions/- particularly those in developing countries/- by the provision of

adequate scientific equipment and access to current scientific literature, for the purpose of achieving and sustaining a critical mass of highly qualified scientists

in these countries;

(c) Develop and expand national scientific and technological databases, processing data in unified formats and systems, and allowing full and open access to the

depository libraries of regional scientific and technological information networks. Promote submission of scientific and technological information and databases

to global or regional data centres and network systems;

(d) Develop and expand regional and global scientific and technological information networks which are based on and linked to national scientific and

technological databases; collect, process and disseminate information from regional and global scientific programmes; expand activities to reduce information

barriers due to language differences. Increase the applications/-particularly in developing countries/- of computer-based retrieval systems in order to cope with

the growth of scientific literature;

(e) Develop, strengthen and forge new partnerships among national, regional and global capacities to promote the full and open exchange of scientific and

technological data and information and to facilitate technical assistance related to environmentally sound and sustainable development. This should be done

through the development of mechanisms for the sharing of basic research, data and information, and the improvement and development of international

networks and centres, including regional linking with national scientific databases, for research, training and monitoring. Such mechanisms should be designed so

as to enhance professional cooperation among scientists in all countries and to establish strong national and regional alliances between industry and research

institutions;

(f) Improve and develop new links between existing networks of natural and social scientists and universities at the international level in order to strengthen

national capacities in the formulation of policy options in the field of environment and development;

(g) Compile, analyse and publish information on indigenous environmental and developmental knowledge, and assist the communities that possess such

knowledge to benefit from them.

Means of implementation

(a) Financing and cost evaluation

35.23. The Conference secretariat has estimated the average total annual cost (1993- 2000) of implementing the activities of this programme to be about $750

million, including about $470 million from the international community on grant or concessional terms. These are indicative and order of magnitude estimates

only and have not been reviewed by Governments. Actual costs and financial terms, including any that are non-concessional, will depend upon, inter alia, the

specific strategies and programmes Governments decide upon for implementation.

(b) Scientific and tech
