Innovative, pragmatic approaches are needed to support sustainable livelihoods and landscape management in complex social-ecological systems (CSES) such as river catchments. In the Tsitsa River Catchment, South Africa, researchers and natural resource managers have come together to apply such innovative approaches. Since CSES are characterised by uncertainty and surprise, understanding and managing them requires a commitment to reflexive praxis and transdisciplinarity. Accordingly, we facilitated a collective reflection and learning process in the project team to deepen our understanding of praxis in CSES. Our findings indicate that CSES thinking created an enabling framing. However, building new linkages among diverse actors to put CSES thinking into practice is challenging, since it requires the development of novel working relationships. Existing institutional structures, power dynamics, and ways of working impose significant constraints. A deeper critical realist analysis of our findings revealed a metaphor which explains why this work is challenging. In this metaphor, the Tsitsa Project team is navigating a bumpy terrain of dialectic tensions. These are tensions for example between natural science and social science, and between science and indigenous knowledge. Based on this metaphor, we suggest an expanding role for scientists and managers, and recommend transformative social learning processes to support teams navigating such bumpy terrains.

Adaptive management (AM) and evidence-based conservation (EBC) have emerged as major decision-making frameworks for conservation management. AM deals with complexity and the importance of local context in making conservation decisions under conditions of high variability, uncertainty, and rapid environmental and social change. EBC seeks for generality from empirical data and aims to develop and enhance best practice. The goal of this review is to explore opportunities for finding common ground between AM and EBC. We propose a framework for distinguishing the subset of conservation problems that are amenable to an evidence-based approach, based on levels of uncertainty, complexity, and social agreement. We then suggest ways for combining multiple lines of evidence and developing greater opportunities for iteration and co-learning in EBC.

There is growing appreciation that protected areas, like all social-ecological systems (SES), are inherently complex and face an unpredictable future under the influence of global environmental change. Adaptive management is the accepted approach for managing complex SES to ensure their resilience, but unless it is supported by a governance system that is itself adaptive it has little chance of success. Scholars have identified certain principles conducive to adaptive governance. Environmental legislation, an important component of the governance system, is often misaligned with these principles. In this paper we assess adaptive governance principles with regard to legislation governing South Africa’s national parks. This assessment indicates that, to enable adaptive governance and adaptive management, legislation should (1) be co-produced by policy-makers, policy implementers and users of protected area ecosystem services; (2) commit and empower management agencies to apply the principles of adaptive governance and adaptive management, particularly in the collaborative development of management plans; (3) commit agencies to review management plans and allow flexibility to adapt plans; (4) ensure that the temporal and spatial scales of the governance system match those of the SES being managed; (5) anticipate change and avoid assumptions of system stability and predictability; and (6) provide for flexible financing mechanisms, so that funds can be prioritised and timed to meet the unpredictable demands of complex systems.

Sub-catchments of the Upper Tsitsa River and the NLEIP Public infrastructure providers National government departments include Department of Water and Sanitation (DWS); Department of Environmental Affairs (DEA); Department of Rural Development and Land Reform (DRDLR) as well as Department of Agriculture Forestry and Fisheries (DAFF). Provincial departments include the Department of Agriculture and Land Affairs; Provincial Department of Economic Development, Environmental Affairs and Tourism; three district municipalities and five local municipalities (identified in the previous section outlining the resource users). The Expanded Public Works Programme (EPWP) is a major provider of public infrastructure. The forestry industry and individual farmers are additional providers of public infrastructure such as road networks, shops, fire-breaks and fences. Research is a form of public infrastructure provision, provided in this study by the Universities of Fort Hare, Rhodes, Free State, and in future also the Walter Sisulu University, and the Agricultural Research Council and private consultants.

Figure 7: Possible changes over time eras in the Tsitsa catchment SES (provided by D. le Maitre). Two historical eras are represented (hunter-gatherer and Khoi-Xhosa) followed by the current modern-day situation, followed by two provocative but plausible future scenarios. Each particular era's SES has the same basic structure – a human system nested in a natural system, with two-way interactions between these; an interlinked internal and endogenous human activity cycle; brown arrows indicating resource loss; and in the current and two possible future eras when influences from outside (of the catchment) are deemed significant, blue arrows connecting endogenous to these outside (exogenous) influences. The two (resilient) historical eras show no or little outside influence, and low resource loss even though the second era has a slightly higher human system imprint. The vulnerable modern era shows an even larger internal human system, with strong back-andforth links to significant outside influence, yet much resource loss (degradation). Two possible futures, diverging depending on how, inter alia, the " irrigation scheme " is handled, show (in the left hand one) that external dependencies can be reduced and a containable human imprint with stronger internal activity and system resilience could lead to lower resource loss. Alternately (right hand scenario) the human imprint can grow, but with little or even negative growth in internal activity, escalating dependency on outside, and possibly even greater resource loss. While Figure 7 is not necessarily accurate, it depicts related elements which do prompt the opportunity to think systemically over time. With refinement, engagement and appropriate presentation, it may possibly act as a basis for a compelling " high road vs low road " portrayal.

The purpose of this document is to develop an initial research investment strategy for the Tsitsa sub-catchment of the Mzimvubu catchment in the Maclear area of the Eastern Cape. The impetus was provided by plans to construct the tenth largest dam in South Africa, Ntabelanga Dam in the ~20 000 km2 catchment, situated in a high relief landscape with erodible soils and a history of land degradation and lost productive capacity. A subsequent dam, the Lalini Dam, will be constructed slightly lower down in the Tsitsa system. The project has been estimated to cost between R12.5 and R20 billion. Although this report deals with the Ntabelanga Dam research opportunity, the same principles (with further learnings) are foundational for the entire project. The macro-context for the project is provided by government’s Strategic Infrastructure Investment Projects (SIPs) and a range of national, provincial and local strategies, plus, importantly, several of the UN’s Sustainable Development Goals (the appropriate ones are listed in Appendix A).

Protected areas (PAs) remain central to the conservation of biodiversity. Classical PAs were conceived as areas that would be set aside to maintain a natural state with minimal human influence. However, global environmental change and growing cross-scale anthropogenic influences mean that PAs can no longer be thought of as ecological islands that function independently of the broader social-ecological system in which they are located. For PAs to be resilient (and to contribute to broader social-ecological resilience), they must be able to adapt to changing social and ecological conditions over time in a way that supports the long-term persistence of populations, communities, and ecosystems of conservation concern. We extend Ostrom's social-ecological systems framework to consider the long-term persistence of PAs, as a form of land use embedded in social-ecological systems, with important cross-scale feedbacks. Most notably, we highlight the cross-scale influences and feedbacks on PAs that exist from the local to the global scale, contextualizing PAs within multi-scale social-ecological functional landscapes. Such functional landscapes are integral to understand and manage individual PAs for long-term sustainability. We illustrate our conceptual contribution with three case studies that highlight cross-scale feedbacks and social-ecological interactions in the functioning of PAs and in relation to regional resilience. Our analysis suggests that while ecological, economic, and social processes are often directly relevant to PAs at finer scales, at broader scales, the dominant processes that shape and alter PA resilience are primarily social and economic.

... For example, lions (Panthera leo) suppress African wild dogs (Lycaon pictus) through intraguild killing and kleptoparasitism, but wild dogs use spatial heterogeneity and fine-scale habitat selection to avoid dominant lions, facilitating the two species coexistence (Davies et al., 2021). In a scenario such as this one, despite a wealth of evidence demonstrating negative interactions between the species in question (Goodheart et al., 2022;Mills & Biggs, 1993;Mills & Gorman, 1977;Swanson et al., 2014), we posit that considering only the occupancy states of the two species could erroneously result in estimation of a positive or independent interaction term as the species co-occur widely. The former could be misinterpreted as conditional occurrence of lions benefitting wild dogs, and the latter of the species not interacting. ...

... In the following sections, we describe a framework for enhancing decision-making practices in fire management for biodiversity conservation. We draw from several fields of research, including adaptive management [82,83], structured decision-making [84] and decision science [41]. The proposed framework (figure 1) encompasses the following steps: (i) specifying objectives and indicators for evaluating management alternatives; (ii) developing management alternatives to address the objectives; (iii) analysing potential consequences and considering trade-offs and uncertainties; and (iv) implementing strategies while monitoring their effectiveness, and sharing results to foster collaboration and new knowledge. ...

... Toward equitable participation, the name of one of the project's principles, was embodied in the Participatory Monitoring, Evaluation, Reflection, and Learning (PMERL) system. Designing equitable and inclusive processes required an understanding of contextual politics and power relations, given the historical and geographical factors contributing to entrenched social injustice, such as the Black homeland legacy shaping access to land, water, and other resources in the Eastern Cape, South Africa (Cockburn et al. 2018). Although it was challenging, the project tried to eliminate power asymmetries by creating conditions for equal and genuine participation and benefit-sharing (Fabricius et al. 2016). ...

... At that time a track record of AM practice had been established, and certain implementation challenges had emerged. The design of SAM was shaped by practical experience of the challenges, as is evident from Rogers' (1998) reply to Walters' (1997) analysis of challenges in AM, as well as the reply of Rogers et al. (2000) to Holling's (1999) essay on the usefulness of visions. These replies indicate how SAM was intended to address the fact that stakeholders frequently differed with regard to their values and expectations related to a social-ecological system. ...

... Applying pluralistic adaptation approaches involves developing a holistic, systems perspective to planning and action to address the complex dynamics of SES and understanding how climate change and other drivers create cascade effects through the system, its elements (Dunlop and Brown 2008) and also how humans respond to climate change (Watson 2014). Identification of tipping points, thresholds of potential concern and limits of acceptable change then provides a basis to translate understanding of system cascades into adaptation actions (Biggs et al. 2011;Freitag et al. 2014). Addressing tipping points and thresholds to avoid maladaptation is a fundamental principle of the adaptation pathways approach (Wise et al. 2014;Fedele et al. 2019). ...

... This paper focuses on one particular implication, which is the need for learning. Ongoing learning is vital to steer programs in complex systems, because it enables implementers to progressively set a course of action and to change course when needed (Woodhill, 2007;Pollard et al., 2011;Roux et al., 2017). In complex contexts even the best program designs cannot simply be "rolled out," but must be experimented with, reflected on, and¾where necessary¾adapted (Patton, 2008(Patton, , 2010Funnell & Rogers, 2011). ...

... To promote successful management, the International Union for Conservation of Nature (IUCN) has directed efforts towards the systematisation and assessment of PA management effectiveness. Such efforts produced a framework based on the principle of adaptive management (Biggs et al., 2011) and the assessment of six elements: context, planning, inputs, processes, outputs and outcomes (Hockings et al., 2006). Following this framework, different methods have been developed to assess PA management effectiveness. ...
