Abstract
Vizag at night is illuminated with 91,000 streetlights that are owned by GVMC. Before Cyclone Hudhud, most of the streetlights used high-pressure sodium-vapor (HPS) or tubular fluorescent lamp (TFLs) technologies. Within GVMC’s jurisdiction, there are 8 zones made up of 72 wards and approximately 4,000 manual points to switch the streetlights on and off. Maintenance was outsourced, with operation and replacement of streetlights handled through a dedicated customer care service center. Registered complaints were forwarded to the assistant engineer of the respective ward or zone and generally addressed within 72 hours. The replacement of HPS and TFL lamps with LED lamps resulted in energy savings of more than 50 percent, along with improvements in road illumination levels. In addition, a central control and monitoring system (CCMS) has been installed that controls the LED streetlights remotely, reduces the time for fault detection, and provides better control of switching and dimming to reduce energy consumption. The CCMS in Vizag is a ‘smart’ system, with information on each light available to be viewed and reported easily via a web-based tool. Vizag also uses the CCMS to measure energy savings, providing the municipality with much more information than they had previously about the energy consumption of their streetlights.

Publication Proven Delivery Models for LED Public Lighting(World Bank, Washington, DC, 2016-10)Birmingham’s light-emitting diode (LED) street lighting project is a small but integral component of a larger, innovative public-private infrastructure modernization effort - the Birmingham Highway Maintenance and Management Private Financing Initiative (HMMPFI) which the Birmingham City Council (BCC) signed with Amey plc on June 7, 2010. The modernization is being done under the PFI framework, which was created by the United Kingdom (UK) government to increase the availability of private financing for capital projects, and to transfer risk to the private sector through joint ventures and leasing agreements. The government has established a clear framework and tools around the PFI in England, including a standard form contract (the Standardization of PFI contract, or SoPC) that is mandatory for public sector use when creating PFI contracts. In the case of Birmingham, the private and public sectors came together in a partnership using private money to fund construction upgrades of the city’s infrastructure system according to set specifications. The partnership also included maintenance of the infrastructure for the remainder of the contract. Other entities, such as utilities, continue to have access to the asset to maintain their specific infrastructure within the public private partnership (PPP).Publication Proven Delivery Models for LED Public Lighting(World Bank, Washington, DC, 2016-10)This paper entitled with Municipal Financing Delivery Model in Quezon City,Philippines, is one in a series of seven knowledge products produced by ESMAP in an attempt to help cities work through the challenges associated with implementing LED public lighting programs. The publications include six case studies and a synthesis report which summarizes the case studies. Each case study describes the context in which decisions were made, then recounts the problems encountered andsolved to realize the implementation of the programs. The challenges include real-life examples of: cities managing to attract private sector participants toprovide necessary financing and technical expertise; programs implemented in municipalities that are not credit worthy and have limited policy and institutional support; small municipalities of about 2,500 residents as well as cities with several million residents; cities managing perceived risks; and cities effectively handling the measurement and verification of electricity savings accruing from the implementation of more efficient LEDs.Publication Proven Delivery Models for LED Public Lighting(World Bank, Washington, DC, 2016-10)The context in Ontario was encouraging for light-emitting diode (LED) programs at federal, provincial, and municipal levels. At the federal level, there were a number of incentive programs funded by the federal gas tax that municipalities tapped into for municipal energy efficiency retrofits and upgrades. The federal gas tax and a yearly transfer from the Government of Canada to each municipality based on population; it is an environmental measure aimed at reducing greenhouse gases. Independent electricity system operator (IESO) has a comprehensive master plan with ambitious energy efficiency goals, implemented with both environmental and economic rationales in mind. IESO’s conservation first framework, developed in 2014, maps out Ontario’s energy conservation goals from 2014 to 2020, emphasizing a coordinated effort within all stages of energy planning, as well as more effective teamwork among sector partners, particularly in support of local distribution companies (LDCs). The global adjustment mechanism fund covers various initiatives, including the province’s energy conservation and demand management programs. As part of this commitment to energy conservation, IESO provides very significant fiscal incentives of up to 30 percent for energy efficiency in the form of energy efficiency infrastructure rebates through a program called save on energy. It is possible that IESO will lower the amount of the outdoor lighting incentive, as it is known, to reflect the growing cost-competitiveness of LEDs in the market without incentives.Publication Proven Delivery Models for LED Public Lighting(World Bank, Washington, DC, 2016-10)Guadalajara, with a population of approximately 1.5 million, is the fourth largest city in Mexico and is located in the country’s central Pacific region. Until the implementation of the current street lighting retrofit project, the city’s outdated street lighting infrastructure had not been renovated in over 30 years. Lighting crews could not keep up with outages reported by citizens and there were many unlit areas around the city. This coincided with increasing crime rates, leading to an overall lack of safety in the city. The outdated infrastructure also required substantial spending on both maintenance and electricity for the streetlights. Street lighting represented approximately 18 percent of electricity consumption and paying for it was a significant component of the city’s budget. To help Guadalajara and other cities address the problem, Mexico’s national government established National Project for Energy Efficiency and Public Municipal Lighting (Proyecto Nacional de Eficiencia Energética en Alumbrado Público Municipal, or National Public Lighting Program). The program provides a significant amount of technical assistance to cities embarking on LED public lighting projects. This case study summarizes the implementation process of LED models for public lighting in Guadalajara.Publication Proven Delivery Models for LED Public Lighting(World Bank, Washington, DC, 2016-10)The project covers seven cities, encompassing nine urban local bodies: seven municipal corporations (MCs) and two urban improvement trusts (UITs). The urban local bodies are responsible for infrastructure improvements in the cities. The cities are spread across three states in central and northwestern India: Rajasthan, Madhya Pradesh, and Maharashtra. They range in size from 260,000 (Alwar) to 2.6 million (Pune), with most in the range of 300,000 to 500,000 inhabitants. Institutionally, municipalities in India are under little regulatory obligation to improve lighting quality to meet standards. India’s Code of Practice for Lighting, created in 1970 by the Bureau of Indian Standards (BIS) to establish lighting standards for categories of streets and roads, and has not been updated since 1981. Further, as USAID report from 2010 notes, ‘since these guidelines are not enforced by any regulatory authority, it is common for municipalities to be unaware of the standards, and many fail to comply.’ Consequently, project upgrades are not driven by regulatory compliance but by municipalities’ initiative to save operating funds on electricity and maintenance, and to improve street lighting quality.

Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.Publication South Asia Development Update, April 2024: Jobs for Resilience(Washington, DC: World Bank, 2024-04-02)South Asia is expected to continue to be the fastest-growing emerging market and developing economy (EMDE) region over the next two years. This is largely thanks to robust growth in India, but growth is also expected to pick up in most other South Asian economies. However, growth in the near-term is more reliant on the public sector than elsewhere, whereas private investment, in particular, continues to be weak. Efforts to rein in elevated debt, borrowing costs, and fiscal deficits may eventually weigh on growth and limit governments' ability to respond to increasingly frequent climate shocks. Yet, the provision of public goods is among the most effective strategies for climate adaptation. This is especially the case for households and farms, which tend to rely on shifting their efforts to non-agricultural jobs. These strategies are less effective forms of climate adaptation, in part because opportunities to move out of agriculture are limited by the region’s below-average employment ratios in the non-agricultural sector and for women. Because employment growth is falling short of working-age population growth, the region fails to fully capitalize on its demographic dividend. Vibrant, competitive firms are key to unlocking the demographic dividend, robust private investment, and workers’ ability to move out of agriculture. A range of policies could spur firm growth, including improved business climates and institutions, the removal of financial sector restrictions, and greater openness to trade and capital flows.Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.Publication The Journey Ahead(Washington, DC: World Bank, 2024-10-31)The Journey Ahead: Supporting Successful Migration in Europe and Central Asia provides an in-depth analysis of international migration in Europe and Central Asia (ECA) and the implications for policy making. By identifying challenges and opportunities associated with migration in the region, it aims to inform a more nuanced, evidencebased debate on the costs and benefits of cross-border mobility. Using data-driven insights and new analysis, the report shows that migration has been an engine of prosperity and has helped address some of ECA’s demographic and socioeconomic disparities. Yet, migration’s full economic potential remains untapped. The report identifies multiple barriers keeping migration from achieving its full potential. Crucially, it argues that policies in both origin and destination countries can help maximize the development impacts of migration and effectively manage the economic, social, and political costs. Drawing from a wide range of literature, country experiences, and novel analysis, The Journey Ahead presents actionable policy options to enhance the benefits of migration for destination and origin countries and migrants themselves. Some measures can be taken unilaterally by countries, whereas others require close bilateral or regional coordination. The recommendations are tailored to different types of migration— forced displacement as well as high-skilled and low-skilled economic migration—and from the perspectives of both sending and receiving countries. This report serves as a comprehensive resource for governments, development partners, and other stakeholders throughout Europe and Central Asia, where the richness and diversity of migration experiences provide valuable insights for policy makers in other regions of the world.Publication Remarks at the United Nations Biodiversity Conference(World Bank, Washington, DC, 2021-10-12)World Bank Group President David Malpass discussed biodiversity and climate change being closely interlinked, with terrestrial and marine ecosystems serving as critically important carbon sinks. At the same time climate change acts as a direct driver of biodiversity and ecosystem services loss. The World Bank has financed biodiversity conservation around the world, including over 116 million hectares of Marine and Coastal Protected Areas, 10 million hectares of Terrestrial Protected Areas, and over 300 protected habitats, biological buffer zones and reserves. The COVID pandemic, biodiversity loss, climate change are all reminders of how connected we are. The recovery from this pandemic is an opportunity to put in place more effective policies, institutions, and resources to address biodiversity loss.
