THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 883:163682. [PMID: 37100128 DOI: 10.1016/j.scitotenv.2023.163682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 03/24/2023] [Accepted: 04/19/2023] [Indexed: 06/03/2023]
Abstract
Landscape structure influences the amount of carbon that can be stored in an ecosystem. Currently, majority of research have been focused on the responses of landscape structure and functional relationships to urbanization, and few have specifically focused on blue-green space. In this study, Beijing was used as a case study to explore the relationship among the blue-green spatial planning structure of green belts, green wedges and green ways, the landscape configuration of blue-green element and carbon storage of urban forest. The blue-green elements were classified using high-resolution remote sensing images (0.8 m) and the above-ground carbon storage estimations of urban forest based on 1307 field survey samples. The results show that green belts and green wedges have a higher coverage percentage of blue-green space and big blue-green patches than that of built-up areas. However, they have lower carbon density in urban forests. The shannon's diversity index of blue-green space was found to have a binary relationship with carbon density, in which, urban forests and water bodies were the key combination in increasing carbon density. The presence of water bodies in urban forests increases the carbon density to up to 1000 m. The effect of farmland and grassland on carbon density was found to be uncertain. With this, this study provides basis for sustainable planning and management of blue-green spaces.

Abstract
Recovery plans in Europe in the COVID-19 pandemic era have stimulated construction-led development, which has eclipsed nature-based agendas in terms of scale, size, and policy. One estimate is that only 0.3% of spending on urban infrastructure globally is directed towards various nature-based solutions and other ecosystem efforts supporting human well-being. In the future we will urgently need to employ nature-based approaches in crisis management for the power and potential of nature to be fully employed in pursuit of urban recovery. We strongly recommend that nature-based approaches be an explicit requirement to secure funding for future recovery plans.

Abstract
Although many governments, financial institutions, and corporations are embracing nature-based solutions as part of their sustainability and net-zero carbon strategies, some nations, Indigenous peoples, local community groups, and grassroots organizations have rejected this term. This pushback is fueled by (i) critical uncertainties about when, where, how, and for whom nature-based solutions are effective and (ii) controversies surrounding their misuse in greenwashing, violations of human rights, and threats to biodiversity. To clarify how the scientific community can help address these issues, I provide an overview of recent research on the benefits and limits of nature-based solutions, including how they compare with technological approaches, and highlight critical areas for future research.
