    Titel: Integrated Pathways for Coherent Land Use Decisions: Untangling and Embracing Complexity in Science-Policy Interfaces in the Sustainable Development Context

    Land assumes multiple roles in social-ecological systems, providing essential ecosystem services for humans and animals alike, such as a food, feed, fiber, timber, energy, freshwater, biodiversity, climate regulation, and pollination (IPBES, 2019; IPCC, 2019). Over the past century, 70% of the global land surface has been exploited by humans, contributing to cumulative climate-, health-, and biodiversity-crises faced by today’s society (IPBES, 2019; IPCC, 2019; UNCCD, 2020). The international community has responded to these complex and inter-linked global environmental problems through a range of cross-cutting and multiscale governance mechanisms, including the Sustainable Development Goals (SDGs) as part of Agenda 2030, one of the key global instruments for addressing multifaceted land issues (Dinerstein et al., 2019; IPBES, 2019). However, the comprehensive nature of the SDGs implies tradeoffs between targets, with some goals entailing higher rates and more destructive forms of land use culminating in adverse impacts on human wellbeing and environmental conditions (IPBES, 2019; UN, 2015, p. 42; UNCCD, 2020).

    With many public interventions to implement Agenda 2030 operating in silos, there are resounding calls for policy coherence that enhances synergies and minimizes conflicts of land use decisions. Scholars emphasize the need for evidence-based advice on integrated policy options that consider inter-dependencies among sectors and creates a common interest to address these challenges (Engels, 2005; UN, 2015, p. 32; UNCCD, 2020; von Maltitz, 2020; Watson, 2005). Science-policy interfaces (SPIs), defined as the exchange of evidence between scientists, policymakers, knowledge holders and users, who can use this information to influence the outcomes of policy decisions on the environment (UNEP, 2017), have the potential to fill knowledge gaps and foster concerted action on complex environmental issues. While SPIs attempt to bridge the traditional disconnect between science and policy, the institutional arrangements and outputs of SPIs are persistently detached from social-political contexts and other interlinked issues (Jabbour & Flachsland, 2017; Koetz, 2011; Koetz et al., 2012; Sarkki et al., 2020). Combined with the lack of collaboration among different SPIs, relevant organizations and diverse actors, their capacity to influence policies is undermined which makes it more challenging for policymakers to tackle the increasing complexity of pressing societal problems, such as, rampant land use change (Koetz, 2011; Koetz et al., 2012; UN, 2015, p. 30).

    Effective sustainability politics hinge on SPIs fulfilling their role of providing policymakers the best available information from diverse knowledge systems on complex problems. In this study, I confront the aforementioned challenges by examining how global SPIs cope with complexity of SDGs related to land use and the extent to which this complex knowledge generated by SPIs is reflected in national decisions on biodiversity conservation and agricultural production in Kenya, a country characterized by mounting land pressures.

    Before I explore these specific dimensions of SPIs, it is crucial to gain a comprehensive understanding of the scholarly discourse on how SPIs impact policy in the sustainable development context as well as the processes and structures SPIs adopt to achieve successful outcomes. Under this first objective I will conduct a systematic review of the literature as well as a discourse analysis through a set of semi-structures interviews with experts and practitioners of global SPIs, such as the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC). For the second objective, I will use social network analysis, quantitative text analysis, process tracing and benchmarking, to identify how and the extent to which formalized, global SPIs cope with complexity. The systematic review will inform a set of independent variables I will develop to explain, firstly, the extent that SPI outputs (assessments and special reports) address complex land use issues (thematic coverage, structure, breadth and length etc.), and, secondly, the extent that SPIs cope with complexity in their outputs (institutional arrangements, networks, diverse stakeholder engagement etc.). In the third objective, I will, initially, use stakeholder identification and analysis to identify the global SPI actors and Kenyan policy actors who interact and exchange complex knowledge on issues of biodiversity conservation and agricultural production, two relevant, potentially synergistic and conflicting issues in Kenya. In a second step I will use quantitative text analysis to assess the extent that global SPIs and core messages related to conflicts and synergies of biodiversity conservation and agricultural production are referenced in national policy documents.

    In sum, the foremost aim of this research project is identifying the range of ways different SPIs at the global context cope with complexity in SDGs related to land use and determining the implications of global SPIs coping with complexity on national policy processes, with Kenya as a case study. The findings will suggest whether particular global SPIs achieve desired outcomes of making a substantive impact on sustainable development. The research findings aim to improve the coherence of land use advice provided by SPIs to developing countries in sub-Saharan Africa, with the potential to mitigate land use conflicts and enhance land use synergies for the sustainable management of natural resources.
