A decision support procedure for the bioeconomy transition: A Colombian case study.

An increasing number of countries and regions consider the bioeconomy transition a strategic policy priority. When approached through the lens of a circular economy perspective, investments in bioeconomy have the potential to enhance resource utilisation efficiency, preserve biodiversity and ecosystems, and foster sustainable development with low emissions. At the same time, if requirements and contextual factors of bioeconomy strategies are not formally analysed, bioeconomic investments might lead to unintended negative consequences. This paper proposes a decision support procedure to design, assess, prioritise, and monitor bioeconomy investments and policies. The flexibility and scalability of our decision support procedure is tested in Colombia to foster a regional and local transition to bioeconomy initiatives that consider the local capital assets and the stakeholders' views. The heterogeneous character of the Colombian environment, economy, society and culture represents an ideal condition to test the strength of the decision support procedure to promote bioeconomy in low and middle-income countries. Our empirical results highlight the benefit of adopting a formal assessment framework that includes strategic national indicators, regional features and stakeholders' views. In terms of the Colombian regional bioeconomy ambitions, we highlight the need for expanding knowledge hubs and participatory stakeholder networks and buttressing appropriate financial mechanisms.

Climate action requires new accounting guidance and governance frameworks to manage carbon in shelf seas.

Accounting guidelines exist for the recording of carbon flows in terrestrial and coastal ecosystems. Shelf sea sediments, while considered an important carbon store, have yet to receive comparable scrutiny. Here, we explore whether effective management of carbon stocks accumulating in shelf seas could contribute towards a nation's greenhouse gas emissions reduction targets. We review the complexities of carbon transport and fate in shelf seas, and the geopolitical challenges of carbon accounting in climate governance because of the transboundary nature of carbon flows in the marine environment. New international accounting guidance and governance frameworks are needed to prompt climate action.

Policy options to achieve culturally-aware and environmentally-sustainable tourism in Fiji.

Increased visitation rates are expected to further impact ecosystems and local communities depending on them to generate income from tourism. We measure how different sustainable tourism management options of such areas in ways that respect the concept of vanua, the Fijian understanding of the connectiveness of the natural environment, humans and traditions, are perceived by a representative sample of potential visitors of the UK population. We then consider some plausible management options and how these may impact welfare. Results show that prospective UK respondents are willing to donate approximately £73 for a management option that enforces medium restrictions by local communities to enter coastal and marine areas in Fiji, so that vanua is respected. A management option that instead denies access to local communities is not seen favourably by prospective UK visitors to Fiji. In terms of time preference, UK respondents, in particular those with previous experiences of tropical areas, prefer environmental projects that restore and protect coastal and marine ecosystems to be completed as soon as possible. Our findings seem to support the introduction of more sustainable and community-based management practices in Fiji as they appear to increase welfare of visitors respecting local traditions and customs, as long as some access is provided to tourists. Donations from tourists or a change in tourism management from a traditional to a more sustainable practice may support the sustainable development of the local coastal communities in Fiji.
