RESUMO

Twenty-five years since foundational publications on valuing ecosystem services for human well-being1,2, addressing the global biodiversity crisis3 still implies confronting barriers to incorporating nature's diverse values into decision-making. These barriers include powerful interests supported by current norms and legal rules such as property rights, which determine whose values and which values of nature are acted on. A better understanding of how and why nature is (under)valued is more urgent than ever4. Notwithstanding agreements to incorporate nature's values into actions, including the Kunming-Montreal Global Biodiversity Framework (GBF)5 and the UN Sustainable Development Goals6, predominant environmental and development policies still prioritize a subset of values, particularly those linked to markets, and ignore other ways people relate to and benefit from nature7. Arguably, a 'values crisis' underpins the intertwined crises of biodiversity loss and climate change8, pandemic emergence9 and socio-environmental injustices10. On the basis of more than 50,000 scientific publications, policy documents and Indigenous and local knowledge sources, the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) assessed knowledge on nature's diverse values and valuation methods to gain insights into their role in policymaking and fuller integration into decisions7,11. Applying this evidence, combinations of values-centred approaches are proposed to improve valuation and address barriers to uptake, ultimately leveraging transformative changes towards more just (that is, fair treatment of people and nature, including inter- and intragenerational equity) and sustainable futures.

RESUMO

Bioeconomy is becoming the main driver transforming European agri-food value chains towards global sustainability in the food supply chain. Intensive horticultural production systems based on medium and low-tech greenhouses are suitable scenarios implementing bioeconomy strategies to achieve sustainability targets. Since the publication of the European Strategy of Bioeconomy in 2012, policy measures intended to boost bioeconomy are responsible for changing what are now considered outdated production systems to more high-tech models capable of responding to climate-change challenges. This article describes the potential for the agri-food supply chain to drive the transition of medium and low-tech intensive greenhouse systems to biobased, circular economy value-chains. Key areas of impact relate to waste valorisation and management, new inputs based on biotechnological innovations, building clusters of innovative delivery partners within the sector, and the increase in public awareness of the impact of the bioeconomy through socio-economic analysis.

RESUMO

Conservation easements are the fastest growing private conservation strategy in the United States. However, mechanisms to assess private land conservation as well as their support by the general public are not well understood. This study uses the ecosystem services framework for assessing existing private lands in Idaho and identifies areas for future conservation easements. Using conservation targets of the land trust as a guide for selecting ecosystem services, we (a) mapped the spatial delivery of conservation targets across public and private lands, (b) explored public awareness in terms of social importance and vulnerability, and (c) mapped future priority areas by characterizing conservation bundles. We found that public lands provided the highest levels of conservation targets, and we found no difference in conservation target provision between private areas and conservation easements. The spatial characterization of conservation target bundles identified potential future priority areas for conservation easements, which can guide planning of land trust conservation efforts.

RESUMO

Globally, current food consumption and trade are placing unprecedented demand on agricultural systems and increasing pressure on natural resources, requiring tradeoffs between food security and environmental impacts especially given the tension between market-driven agriculture and agro-ecological goals. In order to illustrate the wicked social, economic and environmental challenges and processes to find transformative solutions, we focus on the largest concentration of greenhouses in the world located in the semi-arid coastal plain of South-east Spain. Almería family farming, predominantly cooperative, greenhouse intensive production, commenced after the 1960s and has resulted in very significant social and economic benefits for the region, while also having important negative environmental and biodiversity impacts, as well as creating new social challenges. The system currently finds itself in a crisis of diminishing economic benefits and increasing environmental and social dilemmas. Here, we present the outcomes of multi-actor, transdisciplinary research to review and provide collective insights for solutions-oriented research on the sustainability of Almeria's agricultural sector. The multi-actor, transdisciplinary process implemented collectively, and supported by scientific literature, identified six fundamental challenges to transitioning to an agricultural model that aims to ameliorate risks and avoid a systemic collapse, whilst balancing a concern for profitability with sustainability: (1) Governance based on a culture of shared responsibility for sustainability, (2) Sustainable and efficient use of water, (3) Biodiversity conservation, (4) Implementing a circular economy plan, (5) Technology and knowledge transfer, and (6) Image and identity. We conclude that the multi-actor transdisciplinary approach successfully facilitated the creation of a culture of shared responsibility among public, private, academic, and civil society actors. Notwithstanding plural values, challenges and solutions identified by consensus point to a nascent acknowledgement of the strategic necessity to locate agricultural economic activity within social and environmental spheres.This paper demonstrates the need to establish transdisciplinary multi-actor work-schemes to continue collaboration and research for the transition to an agro-ecological model as a means to remain competitive and to create value.

RESUMO

OBJECTIVES: We evaluated the cost-effectiveness of rituximab added to the chemotherapy regimen of fludarabine plus cyclophosphamide (R-FC) versus fludarabine plus cyclophosphamide (FC) for the treatment of patients with previously untreated or relapsed/refractory chronic lymphocytic leukemia (CLL). METHODS: Two Markov models were built, using published results on progression-free survival (PFS) in patients receiving first- or second-line therapy with R-FC vs FC, rates of disease progression and mortality rates in Spain. Patient-elicited utilities were applied to PFS and progressed health states. The cost of drugs, supportive care, and quality-adjusted life years (QALY) were estimated over a 10-year period. Univariate and probabilistic (Monte Carlo) sensitivity analyses were performed. RESULTS: The addition of rituximab to chemotherapy in first- and second-line therapy increased life-years gained (LYG) and QALYs compared with chemotherapy. The incremental cost per LYG and QALY gained was €20,703 and €19,343 for first-line treatment and was €23,183 and €24,781 for second-line treatment. CONCLUSION: In patients with previously untreated or relapsed/refractory CLL, the addition of rituximab to the FC regimen increased life expectancy and quality-adjusted life expectancy. In both types of patient, the treatment was cost-effective.
