Series Statement: Other Financial Accountability Study

Content: In 2009, the G-20 in London recommended that accounting standard setters, strengthen accounting recognition of loan-loss provisions by incorporating a broader range of credit information (G20 2009). In response, the International Accounting Standards Board (IASB) issued International Financial Reporting Standard 9 (IFRS 9) in July 2014, it became effective in 2018. This paper relies on a survey and bilateral meetings with prudential supervisors. This paper deals with the expected credit loss framework, with a particular focus on EMDEs. In 2020, EMDEs were facing challenges when dealing with IFRS 9 during the Coronavirus (COVID-19) pandemic, given the unprecedented reversals in capital flows as global risk appetite declined. EMDEs are coping with weaker health care systems and more limited fiscal space to provide support. Based on the experience of the surveyed countries and their reflections on challenges and potential remedies that they used while implementing the IFRS 9 accounting framework, the authors identified a set of high level policy recommendations for prudential supervisors in emerging markets and developing economies (EMDEs) willing to transition to IFRS 9. The paper is organized as follows: Section 2 presents the survey results; Section 3 presents policy recommendations for supervisory authorities in countries that implemented IFRS 9 as well as in countries that are still in the process of IFRS 9 implementation; and Section 4 offers conclusions

Content: Supply of potable water requires energy and unfortunately most of the countries with minimal access to safe drinking water are also poor in terms of access to reliable energy grids. However, many of such regions have access to other sources of water (such as brackish and groundwater) that can be treated for producing drinking water if correct treatment systems are put in place. Moreover, many of the electrically remote areas are rich in terms of renewable energy (RE) resources (such as wind and solar) which can be potentially employed as the main source of energy for powering water purification systems. Therefore, development and implementation of off‐grid RE powered contaminant removal systems, for producing freshwater from available resources (such as brackish and groundwater), can be considered as an effective and potentially sustainable solution for overcoming the drinking water scarcity issue in remote regions of developing countries. This chapter revises the state of the art related to desalination systems using electrodialysis technology powered by wind energy for decentralised water production

Content: Ecosystem-based management on coral reefs has historically focused on biodiversity conservation through the establishment of marine reserves, but it is increasingly recognised that a subset of species can be key to the maintenance of ecosystem processes and functioning. Specific provisions for these key taxa are essential to biodiversity conservation and resilience-based adaptive management. While a wealth of literature addresses ecosystem functioning on coral reefs, available information covers only a subset of specific taxa, ecological processes and environmental stressors. What is lacking is a comparative assessment across the diverse range of coral reef species to synthesise available knowledge to inform science and management. Here we employed expert elicitation coupled with a literature review to generate the first comprehensive assessment of 70 taxonomically diverse and functionally distinct coral reef species from microbes to top predators to summarise reef functioning. Although our synthesis is largely through the lens of the Great Barrier Reef, Australia, a particularly data-rich system, it is relevant to coral reefs in general. We use this assessment to evaluate which taxa drive processes that maintain a healthy reef, and whether or not management of these taxa is considered a priority (i.e. are they vulnerable?) or is feasible (i.e. can they be managed?). Scientific certainty was scored to weight our recommendations, particularly when certainty was low. We use five case studies to highlight critical gaps in knowledge that limit our understanding of ecosystem functioning. To inform the development of novel management strategies and research objectives, we identify taxa that support positive interactions and enhance ecosystem performance, including those where these roles are currently underappreciated. We conclude that current initiatives effectively capture many priority taxa, but that there is significant room to increase opportunities for underappreciated taxa in both science and management to maximally safeguard coral reef functioning

Content: "Volumen de gran interés. El prólogo y los demás estudios destacan la importancia e influencia de Ortiz en la poesía argentina posterior, los puntos de contacto con poetas como González Tuñón o Enrique Molina, sus características estilísticas, etc. Las notas agregan importante información bibliográfica. En 'Poesía inédita' se incluyen distintos borradores o versiones de poemas lo cual resulta muy revelador del proceso de escritura o composición de Ortiz"--Handbook of Latin American Studies, v. 58
