Mountain regions are particularly vulnerable to climate change impacts. Yet, little is known about local adaptation responses in African mountain regions, especially if these are incremental or transformational. First, using household questionnaires, we interviewed 1,500 farmers across ten African mountain regions to investigate perceived climate change impacts and adaptation responses. Second, through a reflective process involving all co-authors, we identified: (1) main constraints and opportunities for adaptation, and (2) if adaptation was incremental or transformational. Questionnaire data show that farmers in all sites perceive multiple impacts, and that they mostly respond by intensifying farming practices and using off-farm labour. We established that, while several constraints were shared across sites, others were context specific; and that adaptation was mostly incremental, but that certain attributes (for example, social capital) made three sites in East Africa slightly more transformational. 

This material is primarily based upon work supported by the National Science Foundation Graduate Research Fellowship (grant no. DGE-1321845). Addressing complex social-ecological issues requires all relevant sources of knowledge and data, especially those held by communities who remain close to the land. Centuries of oppression, extractive research practices, and misrepresentation have hindered balanced knowledge exchange with Indigenous communities and inhibited innovation and problem-solving capacity in all scientific fields. A recent shift in the research landscape reflects a growing interest in engaging across diverse communities and ways of knowing. Scientific discussions increasingly highlight the inherent value of Indigenous environmental ethics frameworks and processes as the original roadmaps for sustainable development planning, including their potential in addressing the climate crisis and related social and environmental concerns. Momentum in this shift is also propelled by an increasing body of research evidencing the role of Indigenous land stewardship for maintaining ecological health and biodiversity. However, a key challenge straining this movement lies rooted in colonial residue and ongoing actions that suppress and co-opt Indigenous knowledge systems. Scientists working with incomplete datasets privilege a handful of narratives, conceptual understandings, languages, and historical contexts, while failing to engage thousands of collective bodies of intergenerational, place-based knowledge systems. The current dominant colonial paradigm in scientific research risks continued harmful impacts to Indigenous communities that sustain diverse knowledge systems. Here, we outline how ethical standards in researcher practice can be raised in order to reconcile colonial legacies and ongoing settler colonial practices. We synthesize across Indigenous and community-based research protocols and frameworks, transferring knowledge across disciplines, and ground truthing methods and processes in our own practice, to present a relational science working model for supporting Indigenous rights and reconciliation in research. We maintain that core Indigenous values of integrity, respect, humility, and reciprocity should shape researcher responsibilities and methods applied in order to raise ethical standards and long-term relational accountability regarding Indigenous lands, rights, communities, and our shared futures. 

Coffee has been a focal commodity for efforts to promote sustainability and social justice through alternative trade arrangements. Certifications such as Fairtrade have promised better prices, fair labor practices, environmental sustainability and improved livelihoods for small-scale coffee producers. A growing literature has examined alternative trade outcomes, but it remains an open question whether certifications help producers and their organizations improve livelihoods and conserve the environment. This study examines Café Orgánico de Marcala, SA (COMSA), which operates on principles of sustainability that emerged in conjunction with certifications. COMSA supports organic production through education and practices that integrate biodynamic principles, indigenous knowledge, and experimentation. COMSA has used fair trade premiums to build a multilingual school and start a recycling program, among other projects. Members and leaders acknowledge that problems exist yet point to progress. This ethnographic research uses grounded theory to examine COMSA’s approach to sustainability, its successes, and ongoing challenges. 

Environmental governance is recognized as a key issue in many natural and social sciences. It is highly relevant for ecosystem services and common-pool resources as well. Both fields overlap yet have typically been studied separately. Therefore, this study aimed a) to examine the emerging body of literature that incorporates concepts from both fields of research and considers governance challenges, and b) to identify policy tools and recommendations presented for addressing those challenges. The analysis of thirty-nine selected peer-review papers revealed the multiplicity of interacting governance challenges with three major categories: environmental, socioeconomic, and problems of governance itself. Governance is impeded by institutional mismatches, exclusion of local actors, corruption, and perverse policies. The proposed policy recommendations most often suggest changes in institutional arrangements and increasing scientific understanding. Meeting human needs, and increasing social equity and justice were recognized broadly as integral for improving governance, yet correlations among governance problems and solutions appear elusive. These findings extend theoretical reasoning, while carrying practical implications for policy, governance and environmental stewardship. The analysis implies that policies to improve human conditions will be key for improved environmental governance, but more research is needed to learn which types of policy recommendations prove successful given diverse local contexts.
