The role of life cycle assessment (LCA) in informing the development of a sustainable and circular bioeconomy is discussed. We analyse the critical challenges remaining in using LCA and propose improvements needed to resolve future development challenges. Biobased systems are often complex combinations of technologies and practices that are geographically dispersed over long distances and with heterogeneous and uncertain sets of indicators and impacts. Recent studies have provided methodological suggestions on how LCA can be improved for evaluating the sustainability of biobased systems with a new focus on emerging systems, helping to identify environmental and social opportunities prior to large R&D investments. However, accessing economies of scale and improved conversion efficiencies while maintaining compatibility across broad ranges of sustainability indicators and public acceptability remain key challenges for the bioeconomy. LCA can inform, but not by itself resolve this complex dimension of sustainability. Future policy interventions that aim to promote the bioeconomy and support strategic value chains will benefit from the systematic use of LCA. However, the LCA community needs to develop the mechanisms and tools needed to generate agreement and coordinate the standards and incentives that will underpin a successful biobased transition. Systematic stakeholder engagement and the use of multidisciplinary analysis in combination with LCA are essential components of emergent LCA methods. This article is part of the theme issue ‘Bio-derived and bioinspired sustainable advanced materials for emerging technologies (part 1)’.

“…As an example, the water consumption used as a weighting factor for water scarcity CFs should be added to each spatial unit, since it is used for aggregation to larger units such as countries (Jolliet et al 2018). The same applies to uncertainty information, which should be representing total uncertainty, including the uncertainty caused by aggregation, such as was done for water scarcity (Jolliet et al 2018) and soil compaction and water erosion impacts (Sonderegger et al 2020a).…”

“…Our suggestion for a common layer facilitates a direct match of LCI and LCIA methods at an acceptable level of regionalization for standard assessments, while the native resolution of each impact assessment method (e.g., grid cell level for Scherer und Pfister (2016) and Sonderegger et al (2020a)) can still be utilized for foreground processes if a very high spatial level of detail is required. Of utmost importance is that regionalization is quickly implemented in the LCA software solutions in ways that can be practically implemented by mainstream practitioners.…”

The regionalization challenge Life cycle assessment (LCA) and environmental footprints studies have become prominent tools to assess environmental impacts of products, services, companies, and regions, including the impacts over global supply chains. Many impact categories require regional differentiation for life cycle impact assessment (LCIA), but also require regionally explicit life cycle inventory (LCI) data for emissions, water consumption, and land use. There have been many methodological developments to assess such impacts at a regional scale, such as for water scarcity on a watershed-level or land use impacts on an ecoregion-level (Jolliet et al. 2018). Furthermore, a broad range of regional life cycle inventory (LCI) data has been provided, e.g., for land, water, and air emissions (e.g.,

Ademais, é necessário preservar os solos, visto que possuem diversas funções, como o armazenamento de biomassa, nutrientes, organismos e água (Stoessel et al, 2018;Sonderegger et al, 2020), desempenhando um papel único para sustentar todos os ecossistemas, para animais, plantas e seres humanos (Breure et al, 2018).…”

Os efeitos das mudanças climáticas na erosividade possivelmente afetarão os processos erosivos no século 21, tornando emergente a discussão dessa temática. Sendo assim, os objetivos desta revisão de literatura são: traçar as relações entre a variação de perda de solos e erosividade diante de mudanças climáticas, apresentando produtos cartográficos das décadas passadas e para todo o século 21; apresentar um panorama geral de pesquisas (publicadas entre 2016-2020); e demonstrar quais são os desafios e próximos passos na pesquisa sobre esta temática. Para tanto, a pesquisa de artigos foi realizada nas plataformas do Portal de Periódicos da CAPES, Google Scholar e Science Direct, totalizando 33 artigos. Foram consideradas pesquisas de natureza conceitual, com revisões de literatura sobre os temas e de natureza procedimental com cálculos do fator R e estimativas de perda de solos. Os trabalhos consultados mostram que a erosividade estimada e a taxa de perda de solos devem aumentar e diminuir em função das futuras mudanças climáticas. Embora, em escala global, haja estimativas do aumento de erosividade para a área tropical do planeta, atingindo majoritariamente países em desenvolvimento como o Brasil. Isso demonstra a emergência da elaboração de estudos para o país, em escala regional, de bioma e de bacias hidrográficas. Nesse sentido, ressaltamos a importância da abordagem sistêmica, que pode ser proporcionada pela Geografia nos estudos desta temática, visto que os desafios se relacionam a dificuldade de integrar diversos fatores ambientais e obter dados de campo nas modelagens preditivas de perda de solo. Overview of Changes in Rainfall and Erosion Patterns in the Face of Climate Change: Literature Review A B S T R A C TThe effects of climate change on erosivity are likely to affect erosion processes in the 21st century, which makes the discussion emerging. Thus, the goals of this literature review are: to trace the relationship between the variation in soil loss and erosivity in the face of climate change, presenting cartographic products from the past decades and for the entire 21st century; present an overview of research (published between 2016-2021); demonstrate challenges and next steps in research on this topic. Therefore, the search for papers was carried out on the platforms of the CAPES Journal Portal, Google Scholar and Science Direct, totaling 78 papers. Conceptual researches was considered, with literature reviews on the themes and procedural researches with calculations of the R factor and soil loss estimate. The consulted papers show that the estimated erosivity and the rate of soil loss are expected to increase and decrease as a result of future climate changes. Although, on a global scale, there are estimates of the increase in erosivity for the tropical area of the planet, mainly affecting developing countries like Brazil. This demonstrates the emergence of studies for the country, on a regional scale, of biomes and hydrographic basins. In this sense, we emphasize the importance of the systemic approach, which can be provided by Geography in the studies of this theme, since the challenges are related to the difficulty of integrating various environmental factors and obtaining field data in predictive models of soil loss.Keywords: erosivity, extreme precipitation events, global climate models
