The development and climate nexus: the case of sub-Saharan Africa

Abstract This paper explores an alternative approach to future climate policies in developing countries. Although climate change seems marginal compared to the pressing issues of poverty alleviation and economic development, it is becoming clear that the realisation of development goals may be hampered by climate change. However, development can be shaped in such a way as to achieve its goals and at the same time reduce vulnerability to climate change, thereby facilitating sustainable development that realises economic, social, local and global environmental goals. This approach has been coined the ‘development first approach’, in which a future climate regime should focus on development strategies with ancillary climate benefits and increase the capability of developing countries to implement these. This is anticipated to offer a possible positive way out of the current deadlock between North and South in the climate negotiations. First, elements are presented for an integrated approach to development and climate; second, the approach is elaborated for food and energy security in sub-Saharan Africa; and third, possibilities are outlined for international mechanisms to support such integrated development and climate strategies.

Integrating development and climate policies: national and international benefits

What lessons for policy makers at national and international level can be drawn from the growing experiences of reconciling development and climate change? The key to achieving this is to approach the problem from the development perspective, since that is where in most countries the priority lies. Current knowledge on how to realize the benefits of such an integrated approach is assessed. The focus is on the main national development priorities, such as poverty reduction, disaster reduction, rural development, energy supply and transportation. Barriers and promising approaches are identified, based on the experience gained in several countries. The potential is explored for enhancing the global impact of such integrated approaches through replication of national experiences, supported by international organizations. Opportunities for large-scale initiatives are considered at national or regional level. The role of international agreements in fostering integrated development and climate policies is analysed, showing opportunities for achieving large co-benefits for addressing climate change by making use of existing policy frameworks for development and going beyond the UNFCCC framework.

Enhancing the Relevance of Shared Socioeconomic Pathways for Climate Change Impacts, Adaptation and Vulnerability Research

This paper discusses the role and relevance of the shared socioeconomic pathways (SSPs) and the new scenarios that combine SSPs with representative concentration pathways (RCPs) for climate change impacts, adaptation, and vulnerability (IAV) research. It first provides an overview of uses of social–environmental scenarios in IAV studies and identifies the main shortcomings of earlier such scenarios. Second, the paper elaborates on two aspects of the SSPs and new scenarios that would improve their usefulness for IAV studies compared to earlier scenario sets: (i) enhancing their applicability while retaining coherence across spatial scales, and (ii) adding indicators of importance for projecting vulnerability. The paper therefore presents an agenda for future research, recommending that SSPs incorporate not only the standard variables of population and gross domestic product, but also indicators such as income distribution, spatial population, human health and governance.

A new method for analysing socio-ecological patterns of vulnerability

This paper presents a method for the analysis of socio-ecological patterns of vulnerability of people being at risk of losing their livelihoods as a consequence of global environmental change. This method fills a gap in methodologies for vulnerability analysis by providing generalizations of the factors that shape vulnerability in specific socio-ecological systems and showing their spatial occurrence. The proposed method consists of four steps that include both quantitative and qualitative analyses. To start, the socio-ecological system exposed to global environmental changes that will be studied needs to be determined. This could, for example, be farmers in drylands, urban populations in coastal areas and forest-dependent people in the tropics. Next, the core dimensions that shape vulnerability in the socio-ecological system of interest need to be defined. Subsequently, a set of spatially explicit indicators that reflect these core dimensions is selected. Cluster analysis is used for grouping the indicator data. The clusters found, referred to as vulnerability profiles, describe different typical groupings of conditions and processes that create vulnerability in the socio-ecological system under study, and their spatial distribution is provided. Interpretation and verification of these profiles is the last step in the analysis. We illustrate the application of this method by analysing the patterns of vulnerability of (smallholder) farmers in drylands. We identify eight distinct vulnerability profiles in drylands that together provide a global overview of different processes taking place and sub-national detail of their distribution. By overlaying the spatial distribution of these profiles with specific outcome indicators such as conflict occurrence or migration, the method can also be used to understand these phenomena better. Analysis of vulnerability profiles will in a next step be used as a basis for identifying responses to reduce vulnerability, for example, to facilitate the transfer of best practices to reduce vulnerability between different places.

Biodiversity and ecosystem services require IPBES to take novel approach to scenarios

What does the future hold for the world’s ecosystems and benefits that people obtain from them? While the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) has identified the development of scenarios as a key to helping decision makers identify potential impacts of different policy options, it currently lacks a long-term scenario strategy. IPBES will decide how it will approach scenarios at its plenary meeting on 22–28 February 2016, in Kuala Lumpur. IPBES now needs to decide whether it should create new scenarios that better explore ecosystem services and biodiversity dynamics. For IPBES to capture the social-ecological dynamics of biodiversity and ecosystem services, it is essential to engage with the great diversity of local contexts, while also including the global tele-coupling among local places. We present and compare three alternative scenario strategies that IPBES could use and then suggest a bottom-up, cross-scale scenario strategy to improve the policy relevance of future IPBES assessments. We propose five concrete steps as part of an effective, long term scenario development process for IPBES in cooperation with the scientific community.

Integrating development and climate policies

Social and economic development is strongly related to climate change. It is now well established that climate change and its impacts can have a very negative influence on people and their economies, for example on agriculture or in areas vulnerable to droughts and floods. The livelihoods of the poor, young and elderly will be most seriously undermined by extreme events (e.g. droughts, floods, epidemics) as well as more subtle changes (e.g. different disease vectors, heat stress, changes in growing season). The global effort to fight poverty, confirmed again with the adoption of the Millennium Development Goals, will be seriously hampered if mitigation and adaptation to climate change are not addressed. Paradoxically, social and economic development is the very driver of climate change. The way in which human societies have transformed the land over the past centuries to produce food, timber and fuel, and the use of coal, oil and natural gas to fuel our economies are directly responsible for the strong increase in GHG concentrations in the atmosphere. The trends in exploitation of natural resources and the use of fossil fuel are not changing. Projections into the future show a further decline in the forests and natural vegetation and a further increase in greenhouse gas emissions, exacerbating climate change. The question is how to reconcile the development aspirations of countries with the challenges posed by human-induced climate change. The complex relationship between development and climate change necessitates a two-way approach, embracing:

Formalizing knowledge on international environmental regimes: A first step towards integrating political science in integrated assessments of global environmental change

International environmental regimes are considered key factors in dealing with global environmental change problems. It is important to understand if and how regimes are effective in tackling these problems, which requires knowledge on their potential impact on these problems as well as on their political feasibility. Integrated assessments of global environmental change, which are mainly bio-physical and technology-economic oriented, barely address knowledge on environmental regimes, due to problems in drawing general and policy relevant lessons on regime effectiveness and inherent difficulties in modelling human and social dimensions. This paper presents an innovative approach to formalize knowledge on the effectiveness of environmental regimes, so that scientists from both the political science and integrated assessment domain can understand it, discuss it and contribute to it. We constructed a conceptual framework for the systematic analysis of conditions that influence regime effectiveness and implemented it in a computer model using fuzzy logic methodology. We evaluated the fuzzy model in an ex post case study on four existing international environmental regimes. The model can be used as an aid in analysing the effectiveness of existing or future regimes, highlighting which determinants contribute to success or failure, and it enables systematic and meaningful comparisons between regimes and policy measures. We discovered that formalizing knowledge on environmental regimes in a framework and model enhanced its transparency and deductive power as it forced us to be explicit about our choices and assumptions. Developing and using the framework and model also revealed the lacunae in knowledge in environmental regime theory which may inform regime researchers to further structure and increase their knowledge. By making knowledge on environmental regimes explicit and understandable we have taken an important step towards a better integration of political science in integrated assessments. We believe, however, that this integration is still in its early days and requires further attention in the future.

Multiscale scenarios for nature futures

Targets for human development are increasingly connected with targets for nature, however, existing scenarios do not explicitly address this relationship. Here, we outline a strategy to generate scenarios centred on our relationship with nature to inform decision-making at multiple scales.

How Can the European Union Contribute to a COP-6 Agreement? An Overview for Policy Makers

During the 6th Conference of Parties (COP-6) in The Hague, the Netherlands, November 2000, crucial progress on a number of outstanding issues related to the Kyoto Protocol will have to be made to open the way for its early ratification, if not to save it from complete failure. Given the present lack of internal US political support for the Kyoto Protocol, the EU may play a pivotal role in making the Kyoto Protocol agreement a reality even without initial ratification of the US, if its able to provide sufficient leadership. In this overview article we discuss the main issues under negotiation, the problems of finding agreement and opportunities for the EU to catalyse a compromise agreement at COP-6, building on key scientific papers as included in this issue and discussions at the European Forum on Integrated Environmental Assessment Climate Policy Workshop in Amsterdam. Key elements are the inclusion of sinks, the use of the Kyoto Protocol mechanisms as a supplement to domestic action and the international compliance system. Domestic implementation of climate policy is a major factor for the EUs credibility.

Armed conflict distribution in global drylands through the lens of a typology of socio-ecological vulnerability

Motivated by an inconclusive debate over implications of resource scarcity for violent conflict, and common reliance on national data and linear models, we investigate the relationship between socio-ecological vulnerability and armed conflict in global drylands on a subnational level. Our study emanates from a global typology of smallholder farmers’ vulnerability to environmental and socioeconomic stresses in drylands. This typology is composed of eight typical value combinations of variables indicating environmental scarcities, resource overuse, and poverty-related factors in a widely subnational spatial resolution. We investigate the relationships between the spatial distribution of these combinations, or vulnerability profiles, and geocoded armed conflicts, and find that conflicts are heterogeneously distributed according to these profiles. Four profiles distributed across low- and middle-income countries comprise all drylands conflicts. Comparing models for conflict incidence using logit regression and receiver operator characteristic analysis based on (1) the set of all seven indicators as independent variables and (2) a single, only vulnerability profile-based variable proves that the nonlinear typology-based variable is the better explanans for conflict incidence. Inspection of the profiles’ value combinations makes this understandable: A systematic explanation of conflict incidence and absence across all degrees of natural resource endowments is only reached through varying importance of poverty and resource overuse depending on the level of endowment. These are nonlinear interactions between the explaining variables. Conflict does not generally increase with resource scarcity or overuse. Comparison with conflict case studies showed both good agreement with our results and promise in expanding the set of indicators. Based on our findings and supporting literature, we argue that part of the debate over implications of resource scarcity for violent conflict in drylands may be resolved by acknowledging and accounting for nonlinear processes.
