Current social-technical and political conditions threaten the integrity of the Amazon biome. Overcoming these lock-ins requires structural transformations away from conventional economies towards 'socio-bioeconomies' (SBEs). SBEs are economies based on the sustainable use and restoration of Amazonian ecosystems, as well as Indigenous and rural livelihood systems in the region. They include sustainable eco-tourism as well as diversified production and innovative processing of fruits, nuts, oils, medicines, fish and other products deriving from socio-biodiversity. Using a sustainability transitions perspective, we argue for multi-scalar policy changes to sustain, enhance and scale-out and scale-up SBE initiatives. To nurture niche SBE acitivities, we advocate for improvements in infrastructure, value chains and social organizations. To dismantle structural barriers, we call for an end to harmful subsidies, greater representation of marginalized communities in territorial planning, enhanced rural-urban and intersectoral linkages, international collaboration, shifts in demand, and changes in conservation and production narratives. Policies for SBEs must also use clear definitions, participatory processes and a multi-biome approach to avoid perverse outcomes., (© 2024. Springer Nature Limited.)

Some coupled land-climate models predict a dieback of Amazon forest during the twenty-first century due to climate change, but human land use in the region has already reduced the forest cover. The causation behind land use is complex, and includes economic, institutional, political and demographic factors. Pre-eminent among these factors is road building, which facilitates human access to natural resources that beget forest fragmentation. While official government road projects have received considerable attention, unofficial road building by interest groups is expanding more rapidly, especially where official roads are being paved, yielding highly fragmented forest mosaics. Effective governance of natural resources in the Amazon requires a combination of state oversight and community participation in a 'hybrid' model of governance. The MAP Initiative in the southwestern Amazon provides an example of an innovative hybrid approach to environmental governance. It embodies a polycentric structure that includes government agencies, NGOs, universities and communities in a planning process that links scientific data to public deliberations in order to mitigate the effects of new infrastructure and climate change.

Conventional graduate training related to tropical conservation and development has typically separated the two fields, with students focusing on either conservation from the perspective of the biophysical sciences or development as an extension of the social sciences. On entering the workforce, however graduates find they are required to work beyond disciplinary boundaries to address the complex interconnectivity between biological conservation and human well-being. We devised a framework for graduate education that broadens students' skill sets to learn outside their immediate disciplines and think in terms of linked socioecological systems, work in teams, communicate in nonacademic formats, and reflect critically on their own perspectives and actions. The University of Florida's Tropical Conservation and Development program has adopted a learning and action platform that blends theory, skills, and praxis to create an intellectual, social, and professionally safe space where students, faculty, and other participants can creatively address the complex challenges of tropical conservation and development. This platform operates within a nondegree-granting program and includes core courses that are taught by a team of biophysical and social scientists. It incorporates a range of alternative learning spaces such as student-led workshops, retreats, visiting professionals, practitioner experiences, and a weekly student-led seminar that collectively encourage students and faculty to enhance their skills and systematically and thoroughly reflect on program activities. Challenges to the described approach include increased service demands on faculty, a redefinition of research excellence to include effective and equitable collaboration with host-country partners, and the trade-offs and uncertainties inherent in more collaborative, interdisciplinary research. Despite these challenges, growing interdisciplinary programs, coupled with adaptive educational approaches that emphasize learning and action networks of students, faculty, and field partners, provide the best hope for responding to the emerging challenges of tropical conservation and development.
