The Path toward a resilient Europe
No full textThis policy note focuses on the welfare impact of the cost-of-living crisis across EU countries,
regions, and sub-populations. The COVID-19 crisis and the spillovers from the war in Ukraine have had asymmetric effects both across and within countries depending on household characteristics and main sources of income. The recovery has been heterogeneous across regions in the EU and across population segments in the 4 EU countries in light of the cost-of-living crisis and expected growth deceleration. There are two key welfare channels affecting households: the employment and the expenditure channel. First, we describe the employment channel by characterizing the more recent labor market trends and the shape of the recovery across subregions and population subgroups for 2019Q3-2022Q3. Since the beginning of 2021, the labor market experienced a rebound in employment in line with the resumption
of economic activity on the back of solid vaccination campaigns. Though promising, the headline figure does not accurately depict the differences in the labor market's rebound across countries or employment types. Since much of the inequality prevalent throughout the EU is due to inequality in the labor market, uneven recovery in the labor market has implications for widening income inequality. Second, we describe the expenditure channel: the welfare impacts of rising prices (overall, by regions and across groups) due to loss in purchasing power and impacts on living conditions. Our results show that welfare losses could be sizable, particularly at the bottom of the distribution, with indirect or second-order impacts playing an important role. Finally, given these challenges, we describe what we expect in the medium term and
potential policy options to tackle them
A Justificativa Econômica para Reduzir a Vulnerabilidade da Infraestrutura de Transportes aos Desastres Naturais
No full textBrazil’s transport infrastructure and the social and economic activities it supports face increasing exposure to climate and natural hazards, with climate change intensifying risks to critical corridors such as those used for soybean exports. Proactive investments and maintenance programs aimed at climate adaptation of key transport assets can help Brazil avoid costly delays, detours, and expensive reconstruction efforts, offering high returns on investment. In addition, robust emergency response mechanisms within the transport sector are essential to minimize economic losses caused by traffic disruptions.A infraestrutura de transporte no Brasil, bem como as atividades sociais e econômicas que dela dependem, está sujeita a riscos significativos decorrentes de eventos climáticos e desastres naturais. As mudanças climáticas intensificam essa vulnerabilidade, afetando diretamente corredores logísticos estratégicos, como aqueles utilizados para o escoamento de commodities agrícolas, incluindo a soja. Investimentos proativos e programas de manutenção voltados à adaptação climática das infraestruturas de transporte mais críticas podem evitar atrasos e desvios dispendiosos, além de custos elevados com a reconstrução de ativos estratégicos. Essas iniciativas apresentam elevado retorno sobre os investimentos. Além disso, mecanismos de gestão de riscos e de resposta emergencial no setor de transportes é crucial para minimizar perdas econômicas decorrentes da paralisação de fluxos logísticos
Mine Closure Standards and Improved Post-Closure Risk Management for Surface and Underground Coal Mines
No full textThis document consists of a summary of best practice standards for coal mine closure and aftercare, complemented by a practitioner’s guide. In combination, these two modules can be used by coal enterprises, line ministries, technical agencies, as well as development partners, looking towards mine closures some 5-10 years ahead, to inform plans for closure, repurposing, and transition that have yet to be drafted. The document aims to serve as a benchmark and reference for the World Bank's coal transition engagements, providing global good practice guidance for coal enterprises and line ministries, as well as development partners. At the same time, the two modules serve as a risk-management tool in a type of engagement that is by its very nature characterized by a high environmental and social risk baseline. The two modules are designed to support the planning and implementation of mine closures, repurposing, and transitions in a forward-looking manner over the next 5-10 years. Additionally, the document functions as a risk-management tool, ensuring thorough understanding and management of environmental and social risks associated with coal mine closure and post-closure aftercare. These standards and guidance will be integrated into the World Bank's systematic coal transition approach, available to staff and clients. In conjunction with the Environmental and Social Framework (ESF), this work underscores the World Bank's commitment to proportionate due diligence and global knowledge sharing in coal mine closure practices
Growth, Jobs, and the Quest for Productivity. Philippines Growth and Jobs Report
No full textFaster growth was driven by pro-investment reforms implemented in a period of high returns to investment and facilitated by public foundational infrastructure investment. Macroeconomic and structural reforms enhanced stability and lowered investment costs. Public investment, increasing from 2.5 to 5.0 percent of GDP on average in the past decade, contributed to providing some of the public goods needed. Given the remaining gaps in investment relative to global standards, these reforms led to high returns to private investment, creating the right conditions to attract more investment from home and abroad, particularly to lagging regions. Spatial convergence became another engine of growth. A more complex external environment and ambitious national targets call for accelerating growth and improving labor outcomes. Potential growth must rise to create more productive jobs. This requires improved connectivity infrastructure, better local governance, and innovation policies to enhance productivity, together with regulatory and trade reforms to optimize resource allocation and tap into the global economy. It also requires stronger skills to prepare for the jobs of the future. In the following six chapters, this report looks at these issues in detail. The first two chapters look at macro and micro features of growth and job creation. They centrally position better labor outcomes as an objective of faster growth. They examine how policies supported or inhibited job creation and growth, and provide long-term growth projections. The subsequent three chapters look at specific development challenges. Chapter 3 looks at spatial growth and job creation dynamics; Chapter 4 looks at technology adoption and productivity dynamics; and Chapter 5 looks at how climate events affect firms’ performance and decisions on investment and jobs
PENGARUH KONSENTRASI ASAM ASETAT TERHADAP KARAKTERISTIK GELATIN DARI KULIT KAKI AYAM BROILER
No full textChicken feet skin is a part of chicken feet that consists of collagen, fat, and connective tissue. Chicken feet skin has a potential of about 156,933 tons/year. This study was conducted to determine the effect of acetic acid concentration on the characteristics of gelatin from broiler leg skin. The first process was the deproteinization process using NaOH solution with a concentration of 0.15% and a soaking time of 2 x 40 minutes; the second process was the demineralization process using CH3COOH solution with a concentration variation of 0.5%, 1%, 1.5%, 2%, and 2.5% and a soaking time of 4 hours; the third process was the hydrolysis process with water using a waterbath at 60°C for 5 hours. The results showed that the best acetic acid concentration variation was obtained at 2.5% acetic acid concentration with a yield of 6.12%, 4.09% moisture content and 1.59% ash content and has met the SNI 06-3735 standard in 1995
PENCEGAHAN KENDALA DALAM TRANSFER PRODUCED WATER NILAM KE BADAK DENGAN SIMULASI & ANALISIS PENGGANTIAN PIPA 12” HDPE MENJADI PIPA 6” CS
No full textProduced water is the main liquid waste in the oil and gas production process that must be safely transferred to the processing facility. The current produced water transfer system in the Nilam Field uses 12” HDPE pipes, but this material has limitations in terms of high pressure and potential deformation. This study aims to analyze the technical feasibility of replacing 12” HDPE pipes with 6” carbon steel (CS) pipes through hydraulic simulations using Aspen HYSYS and further calculations using Microsoft Excel. The main variables analyzed include pressure drop, flow velocity, and the maximum limit of the replacement pipe length that is still operationally safe. The simulation results show that the pressure drop of 6” pipes is greater than that of 12” pipes, so an evaluation of the maximum length of the pipe that can be replaced is necessary. The analysis results show that 12” pipes can only be replaced with 6” CS pipes with a maximum length of 2,025.97 meters, before the pressure drop and pressure surge exceed the operational safety limit. Thus, pipe replacement can only be done partially and it is not recommended to replace the entire existing pipeline
