RESUMO

Infrastructure development is a major driver of biodiversity loss globally. With upward of US$2.5 trillion in annual investments in infrastructure, the financial sector indirectly drives this biodiversity loss. At the same time, biodiversity safeguards (project-level biodiversity impact mitigation requirements) of infrastructure financiers can help limit this damage. The coverage and harmonization of biodiversity safeguards are important factors in their effectiveness and therefore warrant scrutiny. It is equally important to examine the extent to which these safeguards align with best-practice principles for biodiversity impact mitigation outlined in international policies, such as that of the International Union for Conservation of Nature. We assessed the biodiversity safeguards of public development banks and development finance institutions for coverage, harmonization, and alignment with best practice. We used Institute of New Structural Economics and Agence Française de Développement's global database to identify development banks that invest in high-biodiversity-footprint infrastructure and have over US$500 million in assets. Of the 155 banks, 42% (n = 65) had biodiversity safeguards. Of the existing safeguards, 86% (56 of 65) were harmonized with International Finance Corporation (IFC) Performance Standard 6 (PS6). The IFC PS6 (and by extension the 56 safeguard policies harmonized with it) had high alignment with international best practice in biodiversity impact mitigation, whereas the remaining 8 exhibited partial alignment, incorporating few principles that clarify the conditions for effective biodiversity offsetting. Given their dual role in setting benchmarks and leveraging private finance, infrastructure financiers in development finance need to adopt best-practice biodiversity safeguards if the tide of global biodiversity loss is to be stemmed. The IFC PS6, if strengthened, can act as a useful template for other financier safeguards. The high degree of harmonization among safeguards is promising, pointing to a potential for diffusion of practices.


Evaluación mundial de las salvaguardas para la biodiversidad de los bancos del desarrollo que financian la infraestructura Resumen El desarrollo infraestructural es una de las causas principales de la pérdida mundial de biodiversidad. Con más de US$2.5 billones de inversión anual en la infraestructura, el sector financiero impulsa de forma indirecta esta pérdida. Al mismo tiempo, las salvaguardas para la biodiversidad (los requerimientos para la mitigación del impacto sobre la biodiversidad a nivel proyecto) de los financiadores de la infraestructura pueden ayudar a limitar este daño. La cobertura y armonización de estas salvaguardas son factores importantes en su efectividad y por lo tanto requieren de escrutinio. Es igual de importante examinar en qué medida se ajustan estas salvaguardas con los principios de mejores prácticas para mitigar el impacto sobre la biodiversidad esbozados en las políticas internacionales, como las de la UICN. Analizamos las salvaguardas para la biodiversidad de los bancos del desarrollo público y las instituciones de financiamiento para el desarrollo en cuanto a cobertura, armonización y ajuste con las mejores prácticas. Usamos las bases de datos mundiales del Institute of New Structural Economics y de la Agence Française de Développement para identificar los bancos del desarrollo que invierten en infraestructuras con una gran huella de biodiversidad y que tienen más de US$500 millones en activos. De los 155 bancos, el 42% % (n = 65) tenía salvaguardas para la biodiversidad. De éstas, el 86% (56 de 65) armonizaba con el Estándar de Desempeño 6 (PS6) de la Corporación Financiera Internacional (IFC). El PS6 de la IFC (y por extensión, las 56 salvaguardas que armonizan con él) tuvo un gran ajuste con las mejores prácticas internacionales para la mitigación del impacto sobre la biodiversidad, mientras que las ocho faltantes exhibieron un ajuste parcial, pues incorporaban pocos principios que clarificaban las condiciones de una compensación efectiva de biodiversidad. Ya que los financiadores de la infraestructura tienen un papel doble estableciendo referencias e impulsando el financiamiento privado, también necesitan adoptar las mejores prácticas para salvaguardar la biodiversidad si se desea detener la pérdida de biodiversidad mundial. El PS6 de la IFC, si se fortalece, puede fungir como una plantilla útil para los demás financiadores de las salvaguardas. La gran armonización entre las salvaguardas es prometedora y apunta hacia un potencial de difusión de las prácticas.

RESUMO

International attention on the environmental impacts of China's Belt and Road Initiative (BRI) is increasing, but little is known internationally about the large corpus of Chinese BRI environmental research. We present the first systematic review of the Chinese and English-language BRI environmental research, supported with text mining and sentiment analysis. We found that the research is dominated by Chinese authors writing about BRI routes within China in Chinese, even though concerns around BRI are largely about impacts and benefits within host countries, and the volume of publications in English is recently catching up. Different disciplines and methods are well-represented across languages, apart from specific types of Chinese social science papers. The sentiments of academic research are largely neutral and less polarised than media discourse. We recommend that scientists and practitioners should pay more attention to BRI environmental impacts in developing countries and proactively engage local voices.

RESUMO

Open-cut coal mining can seriously disturb and reshape natural landscapes which results in a range of impacts on local ecosystems and the services they provide. To address the negative impacts of disturbance, progressive rehabilitation is commonly advocated. However, there is little research focusing on how these impacts affect ecosystem services within mine sites and changes over time. The aim of this study was to assess the cumulative impacts of mining disturbance and rehabilitation on ecosystem services through mapping and quantifying changes at multiple spatial and temporal scales. Four ecosystem services including carbon sequestration, air quality regulation, soil conservation and water yield were assessed in 1989, 1997, 2005 and 2013. Disturbance and rehabilitation was mapped using LandTrendr algorithm with Landsat. We mapped spatial patterns and pixel values for each ecosystem service with corresponding model and the landscape changes were analyzed with landscape metrics. In addition, we assessed synergies and trade-offs using Spearman's correlation coefficient for different landscape classes and scales. The results showed that carbon sequestration, air quality regulation and water yield services were both positively and negatively affected by vegetation cover changes due to mined land disturbance and rehabilitation, while soil conservation service were mainly influenced by topographic changes. There were strong interactions between carbon sequestration, air quality regulation and water yield, which were steady among different spatial scales and landscape types. Soil conservation correlations were weak and changed substantially due to differences of spatial scales and landscape types. Although there are limitations associated with data accessibility, this study provides a new research method for mapping impacts of mining on ecosystem services, which offer spatially explicit information for decision-makers and environmental regulators to carry out feasible policies, balancing mining development with ecosystem services provision.
