COM/ENV/EPOC/DCD/DAC(2002)2/FINALFOREWORDThis document is an output from the OECD Development and Climate Change project, anactivity being jointly overseen by the (Environment Policy Committee) Working Party on Global andStructural Policies (WPGSP), and the DAC (Development Assistance Committee) Working Party onDevelopment Co-operation and Environment (WPENV). The overall objective of the project is to provideguidance on how to mainstream responses to climate change within economic development planning andassistance policies, with natural resource management as an overarching theme. Insights from the projectwill be shared with the development assistance community in OECD countries, and national and regionalplanners in developing countries.The paper served as a basis for discussions in an initial OECD expert meeting, held in March2002, aimed at constructing a framework for future OECD work on development and climate change. Ittherefore outlines key concepts, relevant principles, and tools for analysis that could support OECD workon this theme.Partly drawing on this report, a subsequent Concept Paper (Agrawala and Berg 2002) outlined amore specific framework for launching and structuring case studies that are now being carried out underthe project. These case studies are focusing on adaptation, to develop an understanding of how climatechange adaptation policies in various natural resource management sectors (e.g. coastal zone, waterresource and forestry management) can be mainstreamed into economic development planning andassistance policies. Although the case studies are principally addressing adaptation policies, they are alsoconsidering opportunities for combined adaptation-mitigation and development outcomes (for example, inthe areas of land use and forest management).Mitigation is also recognised by the international community as a key connection betweeneconomic development and climate change policies. Future work in this project may wish to considermitigation connections more specifically or, drawing on the results of the adaptation and natural resourcemanagement case studies, begin to assess the appropriate balance between investment in adaptation andmitigation options in different national contexts. Mitigation is, therefore, also discussed in this document,alongside vulnerability and adaptation issues. Ultimately, climate change solutions will need to identifyand exploit synergies, as well as seek to balance possible trade-offs, among the multiple objectives ofdevelopment, mitigation, and adaptation policies.The paper was prepared by Mohan Munasinghe (MIND, Sri Lanka).

ld decision makers are looking for new solutions to traditional development issues such as economicstagnation, persistent poverty, hunger, malnutrition, and illness, as well as newer challenges likeenvironmental degradation and globalisation. One key approach that has received growing attention is theconcept of sustainable development or ‘development which lasts’ (WCED 1987). Following the 1992Earth Summit in Rio de Janeiro and the adoption of the United Nations’ Agenda 21, the goal of sustainabledevelopment has become well accepted world-wide (UN 1993).Meanwhile, the threat of global climate change poses an unprecedented challenge to humanity. Whileclimate change is important in the long run, it is crucial to recognise that (especially for the developingcountries) there are a number of other development issues that affect human welfare more immediately –such as hunger and malnutrition, poverty, health, and pressing local environmental issues. Seen from thedevelopment viewpoint, climate change vulnerability, impacts and adaptation are the main elements of theclimate change problem that resonate. Development pathways also determine emission levels, and theyhave implications for mitigation strategies as well.Climate change and development interact in a circular fashion. Alternative development paths willcertainly affect future climate change, and in turn, climate change will have an impact on prospects forsustainable development (for details, see IPCC, 2001). In the same context, climate change may endangerthe success of some development co-operation efforts and vice versa, i.e., some development assistanceefforts could (unintentionally) have repercussion’s for a country’s emission levels or mitigation options, aswell as exacerbate its vulnerability to climate change (Klein 2001).This paper sketches out a broad framework to address the nexus of sustainable development and climatechange. It also draws out some implications for the preparation of future case studies aimed at exploringthe dynamics of climate change vulnerability and adaptation – especially when one goes beyond simplewin-win outcomes, and confronts difficult trade-off situations among conflicting objectives (Burton andvan Aalst 1999, Klein 2001).The paper is organised as follows: Section 2 introduces the concept of sustainable development; Section 3links that concept to climate change. In section 4, tools and methods of integrating and analysing thesocial, economic, and environmental dimensions of this nexus are briefly presented. These ideas areillustrated in section 5, by applying them to specific examples involving climate-related problems acrossthe full range of spatial scales - at the global, national-economy-wide, sub-national-sectoral, andlocal-project levels. Section 6 contains some concluding thoughts and a discussion of implications for casestudies.7

COM/ENV/EPOC/DCD/DAC(2002)2/FINAL2.2.1OVERVIEW OF KEY CONCEPTSSustainable development conceptsWhile no universally acceptable practical definition of sustainable development exists, the concept hasevolved to encompass three major points of view: economic, social and environmental (Figure 1[a]). Eachviewpoint corresponds to a domain (and a system) that has its own distinct driving forces and objectives.The economy is geared mainly towards improving human welfare, primarily through increases in theconsumption of goods and services. The environmental domain focuses on protection of the integrity andresilience of ecological systems. The social domain emphasises the enrichment of human relationships,achievement of individual and group aspirations, and strengthening of values and institutions.Figure 1.

COM/ENV/EPOC/DCD/DAC(2002)2/FINALenvironmental dimensions of sustainable development (as well as other relevant disciplines and paradigms)[Munasinghe 1994, 2001; OECD 2001]. Balance is also needed in the relative emphasis placed ontraditional development (which is more appealing to the South) versus sustainability (which is emphasisedby the North) (Munasinghe1992). The optimality and durability approaches described in Box 1 (below)play key roles in integrating economic, social and environmental issues (Munasinghe 2001).Current approaches to sustainable development draw on the development experience of the 20th century.For example, the dominant development paradigm during the 1950s was growth, focusing mainly onincreasing economic output and consumption. In the 1960s, development thinking shifted towardsequitable growth, where social (distributional) objectives, especially poverty alleviation, were recognizedto be as important as economic efficiency. Since the 1970s, environment has emerged as the third keyelement of (sustainable) development.Broadly speaking, sustainable development may be described as “a process for improving the range ofopportunities that will enable individual human beings and communities to achieve their aspirations andfull potential over a sustained period of time, while maintaining the resilience of economic, social andenvironmental systems” (Munasinghe 1994). In other words, sustainable development requires(i) opportunities for improving economic, social and ecological systems; and (ii) increases in adaptivecapacity (Gunderson and Holling 2001). Expanding the set of opportunities for system improvement willgive rise to development, while increasing adaptive capacity will improve resilience and sustainability. Theevolving behaviour of individuals and communities facilitates learning, the testing of new processes,adaptation, and improvement.The precise definition of sustainable development remains an ideal, elusive (and perhaps unreachable)goal. A less ambitious, but more focused and feasible strategy would merely seek to ‘make developmentmore sustainable’. Such an incremental (or gradient-based) method is more practical, because manyunsustainable activities can be recognised and eliminated. This approach seeks continuing improvements inthe present quality of life at a lower intensity of resource use, hopefully, leaving behind for futuregenerations an undiminished stock of productive assets - manufactured, natural and social capital - that willenhance opportunities for improving their quality of life (Munasinghe 1992).2.2Economic, environmental and social sustainabilityEconomic progress is often evaluated in terms of welfare (or utility) – measured as willingness to pay forgoods and services consumed. The modern concept underlying economic sustainability seeks to maximisethe flow of income or consumption that could be generated while at least maintaining the stock of assets(or capital) which yield these beneficial outputs (Hicks 1946). Economic efficiency plays a key role inensuring both efficient allocation of resources in production, and efficient consumption choices thatmaximise utility. Problems arise in the valuation of non-market outputs (especially social and ecologicalservices), while issues like uncertainty, irreversibility and catastrophic collapse pose additional difficulties(Pearce and Turner 1990).The environmental interpretation of sustainability focuses on the overall viability and health of ecologicalsystems – defined in terms of a comprehensive, multiscale, dynamic, hierarchical measure of resilience,vigour and organisation. Natural resource degradation, pollution and loss of biodiversity are detrimentalbecause they increase vulnerability, undermine system health, and reduce resilience (Perrings andOpschoor 1994; Munasinghe and Shearer 1995) The notion of a "safe threshold" (and the related conceptof "carrying capacity") are important, e.g., to avoid catastrophic ecosystem collapse (Holling 1986).9

COM/ENV/EPOC/DCD/DAC(2002)2/FINALSocial sustainability seeks to reduce vulnerability and maintain the health (i.e., resilience, vigour andorganisation) of social and cultural systems, and their ability to withstand shocks [Chambers 1989; Bohleet al. 1994; Ribot et al. 1996]. Strengthening social values and institutions (like trust and behaviouralnorms), and enhancing human capital (through education) will increase social capital – typically, theaccumulation of capabilities for individuals and groups of people to work together to achieve sharedobjectives. Weakening social values, institutions and equity will reduce the resilience of social systems,and undermine governance. Preserving cultural diversity and cultural capital, strengthening social cohesionand networks of relationships, and reducing destructive conflicts, are integral elements of this approach. Insummary, for both ecological and socioeconomic systems, the emphasis is on improving system health andits dynamic ability to adapt to change across a range of spatial and temporal scales, rather than theconservation of some ‘ideal’ static state.2.3Poverty and equityPoverty eradication is a primary goal of the development community. From the sustainable developmentviewpoint, both poverty and equity have not only economic, but also social and environmental dimensions,and therefore need to be assessed using a comprehensive set of indicators that go beyond incomedistribution alone. For example, economic policies seek to emphasise means of expanding employment andgainful opportunities for poor people through growth, improving access to markets, and increasing bothassets and education. Social policies would focus on empowerment and inclusion, by making institutionsmore responsive to the poor, and removing barriers that exclude disadvantaged groups. Environmentallyrelated measures to help poor people might seek to reduce their vulnerability to resource depletion andnatural disasters, crop failures, loss of employment, sickness, economic shocks, etc.Thus, an important objective of poverty allevia

concept of sustainable development or ‘development which lasts’ (WCED 1987). Following the 1992 Earth Summit in Rio de Janeiro and the adoption of the United Nations’ Agenda 21, the goal of sustainable development has become well accepted world-wide (UN 1993).
