Carbon and water scarcity footprints of banana under current and future climate conditions in the Brazilian semiarid region
Climate change has become a global threat and a cause of uncertainty for numerous economic sectors, particularly agriculture. Several studies addressing the impacts of climate change can be found in the literature; however, studies on strategies to improve sustainability in orchards are scarce. Bananas are of great economic importance in tropical regions, and their production is characterized by high consumption of natural resources, increasing greenhouse gas emissions and environmental impacts. This study aimed to identify critical points in banana production, understand how they influence future footprints, and develop strategies to reduce current footprints. Life cycle assessment was used to estimate water scarcity (ISO 14046) and carbon (ISO 14067) footprints. Results are presented per 1 kg of banana. Primary data from 10-year averages were collected from farms located in the Lower Jaguaribe sub-basin. The results revealed that the carbon footprint ranged from 0.21 to 0.84 kg CO2 eq kg−1 in 2023, whereas the water scarcity footprint reached 1441 m3 eq kg−1. Under the current scenario, yield improvement could reduce carbon footprint by up to 57.9%, and greater efficiency in water use could decrease water footprint by up to 77%. In 2055, projections suggest that improvements in irrigation could lead to reductions of 5% in carbon footprint and 24.9% in water scarcity footprint. The findings of this study highlight the importance of adopting a sustainable approach to banana production, emphasizing the need to improve natural resource management and promote conscious agricultural practices, such as no-till farming and polyculture, which favor carbon sequestration. The use of plants that perform biological nitrogen fixation can reduce the need for nitrogen fertilizers, in alignment with the 2030 Agenda for Sustainable Development. Public policies focused on providing technical assistance to farmers are crucial for achieving environmentally sustainable production and enhancing resilience to climate change and water scarcity.
期刊介绍：
Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action.
Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers.
All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
