N.; Franssen, W.; Arnell, N.; Hydrologie; Landscape functioning, Geocomputation and Hydrology;Future changes in runoff can have important implications for water resources and flooding. In this study, runoff projections from ISI-MIP (Inter-sectoral Impact Model Intercomparison Project) simulations forced with HadGEM2-ES bias-corrected climate data under the Representative Concentration Pathway 8.5 have been analysed for differences between impact models. Projections of change from a baseline period (1981–2010) to the future (2070–2099) from 12 impacts models which contributed to the hydrological and biomes sectors of ISI-MIP were studied. The biome models differed from the hydrological models by the inclusion of CO2 impacts and most also included a dynamic vegetation distribution. The biome and hydrological models agreed on the sign of runoff change for most regions of the world. However, in West Africa, the hydrological models projected drying, and the biome models a moistening. The biome models tended to produce larger increases and smaller decreases in regionally averaged runoff than the hydrological models, although there is large inter-model spread. The timing of runoff change was similar, but there were differences in magnitude, particularly at peak runoff. The impact of vegetation distribution change was much smaller than the projected change over time, while elevated CO2 had an effect as large as the magnitude of change over time projected by some models in some regions. The effect of CO2 on runoff was not consistent across the models, with two models showing increases and two decreases. There was also more spread in projections from the runs with elevated CO2 than with constant CO2. The biome models which gave increased runoff from elevated CO2 were also those which differed most from the hydrological models. Spatially, regions with most difference between model types tended to be projected to have most effect from elevated CO2, and seasonal differences were also similar, so elevated CO2 can partly explain the differences between hydrological and biome model runoff change projections. Therefore, this shows that a range of impact models should be considered to give the full range of uncertainty in impacts studies.

Eglinton;Blanca Ausín; Negar Haghipour; Elena Bruni; Timothy I. Eglinton;Alkenone signatures preserved in marine sedimentary records are considered one of the most robust paleothermometers available and are often used as a proxy for paleoproductivity. However, important gaps remain regarding the provenance and fate of alkenones, as well as their impact on derived environmental signals in marine sediments. Here, we analyze the abundance, distribution and radiocarbon (14C) age of alkenones in bulk sediments and corresponding grain-size fractions in surficial sediments from seven continental margin settings in the Pacific and Atlantic oceans to evaluate the impact of organo-mineral associations and hydrodynamic sorting on sedimentary alkenone signals. We find that alkenones preferentially reside within fine-grained mineral fractions of continental margin sediments, with the preponderance of alkenones residing within the fine-silt fraction (2–10 µm) and most strongly influencing alkenone-14C age and sea surface temperature (SST) signals from bulk sediments as a consequence of their proportional abundance and higher degree of organic matter protection relative to other fractions. Our results provide further evidence for the key role of selective association of alkenones with mineral surfaces and associated hydrodynamic mineral sorting processes on the reliability of alkenone signals encoded in marine sediments (14C age, content and distribution) and the fidelity of corresponding proxy records (productivity and sea SST) in the spatial and temporal domain.

This report provides a survey of the key features associated with greenhouse gas (GHG) monitoring, reporting, and verification (MRV) systems that support the pilot emissions trading schemes (ETS) in China. The seven pilots are: Beijing, Chongqing, Guangdong, Hubei, Shanghai, Shenzhen, and Tianjin. This report has the following structure. (1) It begins with an overview of each ETS, to provide context for the MRV systems of the pilots. (2) The second part includes a summary table of the attributes of the MRV systems for all the pilots. (3) The report concludes with observations about the similarities and differences of the MRV systems for the pilots as well as the published rules and procedures for the national MRV system. The technical challenges for developing the MRV are also identified. Practical aspects of the determination of boundaries, development of methodology, acquisition of activity data, emission factors and evidence for cross check are discussed. Engagement of stakeholders, capacity building and supporting institutions are also explored, as well as lessons learned.

Tsigaridis; K. Tsigaridis; S. Undorf; D. M. Westervelt; D. M. Westervelt;Changes in anthropogenic aerosol emissions have strongly contributed to global and regional trends in temperature, precipitation, and other climate characteristics and have been one of the dominant drivers of decadal trends in Asian and African precipitation. These and other influences on regional climate from changes in aerosol emissions are expected to continue and potentially strengthen in the coming decades. However, a combination of large uncertainties in emission pathways, radiative forcing, and the dynamical response to forcing makes anthropogenic aerosol a key factor in the spread of near-term climate projections, particularly on regional scales, and therefore an important one to constrain. For example, in terms of future emission pathways, the uncertainty in future global aerosol and precursor gas emissions by 2050 is as large as the total increase in emissions since 1850. In terms of aerosol effective radiative forcing, which remains the largest source of uncertainty in future climate change projections, CMIP6 models span a factor of 5, from −0.3 to −1.5 W m−2. Both of these sources of uncertainty are exacerbated on regional scales. The Regional Aerosol Model Intercomparison Project (RAMIP) will deliver experiments designed to quantify the role of regional aerosol emissions changes in near-term projections. This is unlike any prior MIP, where the focus has been on changes in global emissions and/or very idealised aerosol experiments. Perturbing regional emissions makes RAMIP novel from a scientific standpoint and links the intended analyses more directly to mitigation and adaptation policy issues. From a science perspective, there is limited information on how realistic regional aerosol emissions impact local as well as remote climate conditions. Here, RAMIP will enable an evaluation of the full range of potential influences of realistic and regionally varied aerosol emission changes on near-future climate. From the policy perspective, RAMIP addresses the burning question of how local and remote decisions affecting emissions of aerosols influence climate change in any given region. Here, RAMIP will provide the information needed to make direct links between regional climate policies and regional climate change. RAMIP experiments are designed to explore sensitivities to aerosol type and location and provide improved constraints on uncertainties driven by aerosol radiative forcing and the dynamical response to aerosol changes. The core experiments will assess the effects of differences in future global and regional (Africa and the Middle East, East Asia, North America and Europe, and South Asia) aerosol emission trajectories through 2051, while optional experiments will test the nonlinear effects of varying emission locations and aerosol types along this future trajectory. All experiments are based on the shared socioeconomic pathways and are intended to be performed with 6th Climate Model Intercomparison Project (CMIP6) generation models, initialised from the CMIP6 historical experiments, to facilitate comparisons with existing projections. Requested outputs will enable the analysis of the role of aerosol in near-future changes in, for example, temperature and precipitation means and extremes, storms, and air quality.

Dickinson;The evolution of coastal landforms on tropical Pacific islands has been influenced jointly by changes in relative sea level and by shoreline sediment dynamics. During human occupation of Pacific Oceania, changes in sea level have reflected a monotonic hydro-isostatic drawdown in regional sea level following a mid-Holocene highstand in eustatic sea level, and varied patterns of tectonic uplift or subsidence affecting individual islands or island groups. Wave erosion has altered some bold coastlines, but the dominant trend of paleoshoreline evolution along lowland coasts has been the expansion of coastal plains by the accretion of successive beach ridges to island cores as regional sea level gradually fell. Anthropogenic impacts on island landscapes have influenced strandline sedimentation by enhancing sediment delivery to island coasts in response to inland deforestation.

Rood;Evidence for the timing and pace of past grounding line retreat of the Thwaites Glacier system in the Amundsen Sea embayment (ASE) of Antarctica provides constraints for models that are used to predict the future trajectory of the West Antarctic Ice Sheet (WAIS). Existing cosmogenic nuclide surface exposure ages suggest that Pope Glacier, a former tributary of Thwaites Glacier, experienced rapid thinning in the early to mid-Holocene. There are relatively few exposure ages from the lower ice-free sections of Mt. Murphy (<300 m a.s.l.; metres above sea level) that are uncomplicated by either nuclide inheritance or scatter due to localised topographic complexities; this makes the trajectory for the latter stages of deglaciation uncertain. This paper presents 12 new 10Be exposure ages from erratic cobbles collected from the western flank of Mt. Murphy, within 160 m of the modern ice surface and 1 km from the present grounding line. The ages comprise two tightly clustered populations with mean deglaciation ages of 7.1 ± 0.1 and 6.4 ± 0.1 ka (1 SE). Linear regression analysis applied to the age–elevation array of all available exposure ages from Mt. Murphy indicates that the median rate of thinning of Pope Glacier was 0.27 m yr−1 between 8.1–6.3 ka, occurring 1.5 times faster than previously thought. Furthermore, this analysis better constrains the uncertainty (95 % confidence interval) in the timing of deglaciation at the base of the Mt. Murphy vertical profile (∼ 80 m above the modern ice surface), shifting it to earlier in the Holocene (from 5.2 ± 0.7 to 6.3 ± 0.4 ka). Taken together, the results presented here suggest that early- to mid-Holocene thinning of Pope Glacier occurred over a shorter interval than previously assumed and permit a longer duration over which subsequent late Holocene re-thickening could have occurred.

Percival;Total peroxy nitrate ( ∑ PN) concentrations have been measured using a thermal dissociation laser-induced fluorescence (TD-LIF) instrument during the BORTAS campaign, which focused on the impact of boreal biomass burning (BB) emissions on air quality in the Northern Hemisphere. The strong correlation observed between the ∑ PN concentrations and those of carbon monoxide (CO), a well-known pyrogenic tracer, suggests the possible use of the ∑ PN concentrations as marker of the BB plumes. Two methods for the identification of BB plumes have been applied: (1) ∑ PN concentrations higher than 6 times the standard deviation above the background and (2) ∑ PN concentrations higher than the 99th percentile of the ∑ PNs measured during a background flight (B625); then we compared the percentage of BB plume selected using these methods with the percentage evaluated, applying the approaches usually used in literature. Moreover, adding the pressure threshold ( ∼ 750 hPa) as ancillary parameter to ∑ PNs, hydrogen cyanide (HCN) and CO, the BB plume identification is improved. A recurrent artificial neural network (ANN) model was adapted to simulate the concentrations of ∑ PNs and HCN, including nitrogen oxide (NO), acetonitrile (CH3CN), CO, ozone (O3) and atmospheric pressure as input parameters, to verify the specific role of these input data to better identify BB plumes.

The year 2015 is pivotal in international development. In the lead-up to 2000, the global community came together at various conferences to agree on, for the first time in known history, shared development goals. The eight Millennium Development Goals (MDGs) set 18 targets that were aimed at significantly reducing disease, illiteracy, gender inequality, hunger, and poverty, and improving access to water and sanitation by 2015. Leading up to this point where the era of the MDGs concludes, progress has been monitored and discussions started well ahead of this momentous year to define and meet the more ambitious Sustainable Development Goals (SDGs), building on and bringing to fruition what has been started under the MDG agenda. Much progress has been made toward achieving the MDGs. The world reached the poverty reduction target five years ahead of schedule, and progress has been reported in a number of other areas. However, considerable challenges remain: even while declaring success on MDG1, roughly a billion people remained in poverty. A large number of MDG targets will not be met by the end of 2015, and progress remains uneven among the different countries. Moreover, new challenges to progress are emerging deriving from natural and manmade calamities. To deliver on the twin goals and the post-2015 agenda, the Bank Group would benefit from a clearly articulated role, approach, and expected contribution to the SDGs, both externally for enhancing partnerships and internally to facilitate prioritization and synergies. As this paper has shown, the World Bank Group works actively in many areas relevant to the SDGs, actually many more than covered here, but various evaluations have pointed to the importance of multi-sector integrated approaches that challenge countries and their partners to find new ways of working. The challenges that the SDGs aim to address, and the SDGs themselves, are complex, and solutions will have to be tailored to context, bring together multiple actors, and benefit from dynamic, constantly adjusted planning and execution that is informed by ongoing monitoring and evaluation.

Africa is currently experiencing the world's fastest urbanization rate at 3.5 percent annually-placing increasing pressure on resource-constrained local governments to maintain and improve livability standards of their cities. But simultaneously, an 'Information and Communication Technologies' (ICT) revolution has swept across the continent-as evidenced by vastly improved telecommunications and internet infrastructure, leapfrogging mobile communications penetration rates, and emergence of a successful homegrown IT applications industry. This report aims to: 1) synthesize the role currently played by ICT towards improved governance, management and accountability of urban service providers in Africa as well as other regions, 2) explore current ICT initiatives that are relevant to the World Bank's thematic concerns, 3) reconcile existing deficiencies/barriers towards potential for replication, and 4) develop a roadmap to render easy strategy implementation by project teams. Section one outlines evolving trends in urban governance and presents ICT as a potential tool in the environment of modern governance. Section two discusses the role of ICT in some of the Bank's core areas of urban focus, namely: local governance and economic development; intergovernmental fiscal relations and municipal finance; urban poverty and slum upgrading; urban planning, land and housing; urban environment and climate change; and water and sanitation service delivery. An analysis of fundamental ICT methodologies employed is discussed in section three. Section four, in conclusion, suggests an action-plan for enhancing ICT initiatives as a component of the Bank's lending activities.

International audience; Terahertz pulsed imaging has attracted considerable interest for revealing the stratigraphy and hidden features of art paintings. The reconstruction of the stratigraphy is based on the precise extraction of THz echo parameters from the reflected signals. Several historical panel paintings and wall paintings have been well studied by THz reflective imaging, in which the detailed stratigraphy has been successfully revealed. To our knowledge, however, the stratigraphy of oil paintings has not been clearly uncovered by THz imaging, since the paint layers in an oil painting on canvas, especially for the 16 th and 17 th century art works, are usually very thin (~10 m) in the THz regime. Therefore, in order to improve the performance of THz imaging, advanced signal-processing techniques with higher depth-resolution are still needed. In this study, THz reflective imaging is employed to reveal for the first time the detailed stratigraphy of a 17th century Italian oil painting on canvas. The paint layers on the supporting canvas are very thin in the THz regime, as the THz echoes corresponding to the stratigraphy totally overlap in the first cycle of the reflected THz signal. THz sparse deconvolution based on an iterative shrinkage algorithm is utilized to resolve the overlapping echoes. Based on the deconvolved signals, the detailed stratigraphy of this oil painting on canvas, including the varnish, pictorial, underdrawing, and ground layers, is successfully revealed. The THz C-and B-scans based on the THz deconvolved signals also enable us to reveal the features of each layer. Our results thus enhance the capability of terahertz imaging to perform detailed analysis and diagnostics of historical oil paintings on canvas with foreseen applications for the study of the artist's technique and for authentication.

N.; Franssen, W.; Arnell, N.; Hydrologie; Landscape functioning, Geocomputation and Hydrology;Future changes in runoff can have important implications for water resources and flooding. In this study, runoff projections from ISI-MIP (Inter-sectoral Impact Model Intercomparison Project) simulations forced with HadGEM2-ES bias-corrected climate data under the Representative Concentration Pathway 8.5 have been analysed for differences between impact models. Projections of change from a baseline period (1981–2010) to the future (2070–2099) from 12 impacts models which contributed to the hydrological and biomes sectors of ISI-MIP were studied. The biome models differed from the hydrological models by the inclusion of CO2 impacts and most also included a dynamic vegetation distribution. The biome and hydrological models agreed on the sign of runoff change for most regions of the world. However, in West Africa, the hydrological models projected drying, and the biome models a moistening. The biome models tended to produce larger increases and smaller decreases in regionally averaged runoff than the hydrological models, although there is large inter-model spread. The timing of runoff change was similar, but there were differences in magnitude, particularly at peak runoff. The impact of vegetation distribution change was much smaller than the projected change over time, while elevated CO2 had an effect as large as the magnitude of change over time projected by some models in some regions. The effect of CO2 on runoff was not consistent across the models, with two models showing increases and two decreases. There was also more spread in projections from the runs with elevated CO2 than with constant CO2. The biome models which gave increased runoff from elevated CO2 were also those which differed most from the hydrological models. Spatially, regions with most difference between model types tended to be projected to have most effect from elevated CO2, and seasonal differences were also similar, so elevated CO2 can partly explain the differences between hydrological and biome model runoff change projections. Therefore, this shows that a range of impact models should be considered to give the full range of uncertainty in impacts studies.

Eglinton;Blanca Ausín; Negar Haghipour; Elena Bruni; Timothy I. Eglinton;Alkenone signatures preserved in marine sedimentary records are considered one of the most robust paleothermometers available and are often used as a proxy for paleoproductivity. However, important gaps remain regarding the provenance and fate of alkenones, as well as their impact on derived environmental signals in marine sediments. Here, we analyze the abundance, distribution and radiocarbon (14C) age of alkenones in bulk sediments and corresponding grain-size fractions in surficial sediments from seven continental margin settings in the Pacific and Atlantic oceans to evaluate the impact of organo-mineral associations and hydrodynamic sorting on sedimentary alkenone signals. We find that alkenones preferentially reside within fine-grained mineral fractions of continental margin sediments, with the preponderance of alkenones residing within the fine-silt fraction (2–10 µm) and most strongly influencing alkenone-14C age and sea surface temperature (SST) signals from bulk sediments as a consequence of their proportional abundance and higher degree of organic matter protection relative to other fractions. Our results provide further evidence for the key role of selective association of alkenones with mineral surfaces and associated hydrodynamic mineral sorting processes on the reliability of alkenone signals encoded in marine sediments (14C age, content and distribution) and the fidelity of corresponding proxy records (productivity and sea SST) in the spatial and temporal domain.

This report provides a survey of the key features associated with greenhouse gas (GHG) monitoring, reporting, and verification (MRV) systems that support the pilot emissions trading schemes (ETS) in China. The seven pilots are: Beijing, Chongqing, Guangdong, Hubei, Shanghai, Shenzhen, and Tianjin. This report has the following structure. (1) It begins with an overview of each ETS, to provide context for the MRV systems of the pilots. (2) The second part includes a summary table of the attributes of the MRV systems for all the pilots. (3) The report concludes with observations about the similarities and differences of the MRV systems for the pilots as well as the published rules and procedures for the national MRV system. The technical challenges for developing the MRV are also identified. Practical aspects of the determination of boundaries, development of methodology, acquisition of activity data, emission factors and evidence for cross check are discussed. Engagement of stakeholders, capacity building and supporting institutions are also explored, as well as lessons learned.

Tsigaridis; K. Tsigaridis; S. Undorf; D. M. Westervelt; D. M. Westervelt;Changes in anthropogenic aerosol emissions have strongly contributed to global and regional trends in temperature, precipitation, and other climate characteristics and have been one of the dominant drivers of decadal trends in Asian and African precipitation. These and other influences on regional climate from changes in aerosol emissions are expected to continue and potentially strengthen in the coming decades. However, a combination of large uncertainties in emission pathways, radiative forcing, and the dynamical response to forcing makes anthropogenic aerosol a key factor in the spread of near-term climate projections, particularly on regional scales, and therefore an important one to constrain. For example, in terms of future emission pathways, the uncertainty in future global aerosol and precursor gas emissions by 2050 is as large as the total increase in emissions since 1850. In terms of aerosol effective radiative forcing, which remains the largest source of uncertainty in future climate change projections, CMIP6 models span a factor of 5, from −0.3 to −1.5 W m−2. Both of these sources of uncertainty are exacerbated on regional scales. The Regional Aerosol Model Intercomparison Project (RAMIP) will deliver experiments designed to quantify the role of regional aerosol emissions changes in near-term projections. This is unlike any prior MIP, where the focus has been on changes in global emissions and/or very idealised aerosol experiments. Perturbing regional emissions makes RAMIP novel from a scientific standpoint and links the intended analyses more directly to mitigation and adaptation policy issues. From a science perspective, there is limited information on how realistic regional aerosol emissions impact local as well as remote climate conditions. Here, RAMIP will enable an evaluation of the full range of potential influences of realistic and regionally varied aerosol emission changes on near-future climate. From the policy perspective, RAMIP addresses the burning question of how local and remote decisions affecting emissions of aerosols influence climate change in any given region. Here, RAMIP will provide the information needed to make direct links between regional climate policies and regional climate change. RAMIP experiments are designed to explore sensitivities to aerosol type and location and provide improved constraints on uncertainties driven by aerosol radiative forcing and the dynamical response to aerosol changes. The core experiments will assess the effects of differences in future global and regional (Africa and the Middle East, East Asia, North America and Europe, and South Asia) aerosol emission trajectories through 2051, while optional experiments will test the nonlinear effects of varying emission locations and aerosol types along this future trajectory. All experiments are based on the shared socioeconomic pathways and are intended to be performed with 6th Climate Model Intercomparison Project (CMIP6) generation models, initialised from the CMIP6 historical experiments, to facilitate comparisons with existing projections. Requested outputs will enable the analysis of the role of aerosol in near-future changes in, for example, temperature and precipitation means and extremes, storms, and air quality.

Dickinson;The evolution of coastal landforms on tropical Pacific islands has been influenced jointly by changes in relative sea level and by shoreline sediment dynamics. During human occupation of Pacific Oceania, changes in sea level have reflected a monotonic hydro-isostatic drawdown in regional sea level following a mid-Holocene highstand in eustatic sea level, and varied patterns of tectonic uplift or subsidence affecting individual islands or island groups. Wave erosion has altered some bold coastlines, but the dominant trend of paleoshoreline evolution along lowland coasts has been the expansion of coastal plains by the accretion of successive beach ridges to island cores as regional sea level gradually fell. Anthropogenic impacts on island landscapes have influenced strandline sedimentation by enhancing sediment delivery to island coasts in response to inland deforestation.

Rood;Evidence for the timing and pace of past grounding line retreat of the Thwaites Glacier system in the Amundsen Sea embayment (ASE) of Antarctica provides constraints for models that are used to predict the future trajectory of the West Antarctic Ice Sheet (WAIS). Existing cosmogenic nuclide surface exposure ages suggest that Pope Glacier, a former tributary of Thwaites Glacier, experienced rapid thinning in the early to mid-Holocene. There are relatively few exposure ages from the lower ice-free sections of Mt. Murphy (<300 m a.s.l.; metres above sea level) that are uncomplicated by either nuclide inheritance or scatter due to localised topographic complexities; this makes the trajectory for the latter stages of deglaciation uncertain. This paper presents 12 new 10Be exposure ages from erratic cobbles collected from the western flank of Mt. Murphy, within 160 m of the modern ice surface and 1 km from the present grounding line. The ages comprise two tightly clustered populations with mean deglaciation ages of 7.1 ± 0.1 and 6.4 ± 0.1 ka (1 SE). Linear regression analysis applied to the age–elevation array of all available exposure ages from Mt. Murphy indicates that the median rate of thinning of Pope Glacier was 0.27 m yr−1 between 8.1–6.3 ka, occurring 1.5 times faster than previously thought. Furthermore, this analysis better constrains the uncertainty (95 % confidence interval) in the timing of deglaciation at the base of the Mt. Murphy vertical profile (∼ 80 m above the modern ice surface), shifting it to earlier in the Holocene (from 5.2 ± 0.7 to 6.3 ± 0.4 ka). Taken together, the results presented here suggest that early- to mid-Holocene thinning of Pope Glacier occurred over a shorter interval than previously assumed and permit a longer duration over which subsequent late Holocene re-thickening could have occurred.

Percival;Total peroxy nitrate ( ∑ PN) concentrations have been measured using a thermal dissociation laser-induced fluorescence (TD-LIF) instrument during the BORTAS campaign, which focused on the impact of boreal biomass burning (BB) emissions on air quality in the Northern Hemisphere. The strong correlation observed between the ∑ PN concentrations and those of carbon monoxide (CO), a well-known pyrogenic tracer, suggests the possible use of the ∑ PN concentrations as marker of the BB plumes. Two methods for the identification of BB plumes have been applied: (1) ∑ PN concentrations higher than 6 times the standard deviation above the background and (2) ∑ PN concentrations higher than the 99th percentile of the ∑ PNs measured during a background flight (B625); then we compared the percentage of BB plume selected using these methods with the percentage evaluated, applying the approaches usually used in literature. Moreover, adding the pressure threshold ( ∼ 750 hPa) as ancillary parameter to ∑ PNs, hydrogen cyanide (HCN) and CO, the BB plume identification is improved. A recurrent artificial neural network (ANN) model was adapted to simulate the concentrations of ∑ PNs and HCN, including nitrogen oxide (NO), acetonitrile (CH3CN), CO, ozone (O3) and atmospheric pressure as input parameters, to verify the specific role of these input data to better identify BB plumes.

The year 2015 is pivotal in international development. In the lead-up to 2000, the global community came together at various conferences to agree on, for the first time in known history, shared development goals. The eight Millennium Development Goals (MDGs) set 18 targets that were aimed at significantly reducing disease, illiteracy, gender inequality, hunger, and poverty, and improving access to water and sanitation by 2015. Leading up to this point where the era of the MDGs concludes, progress has been monitored and discussions started well ahead of this momentous year to define and meet the more ambitious Sustainable Development Goals (SDGs), building on and bringing to fruition what has been started under the MDG agenda. Much progress has been made toward achieving the MDGs. The world reached the poverty reduction target five years ahead of schedule, and progress has been reported in a number of other areas. However, considerable challenges remain: even while declaring success on MDG1, roughly a billion people remained in poverty. A large number of MDG targets will not be met by the end of 2015, and progress remains uneven among the different countries. Moreover, new challenges to progress are emerging deriving from natural and manmade calamities. To deliver on the twin goals and the post-2015 agenda, the Bank Group would benefit from a clearly articulated role, approach, and expected contribution to the SDGs, both externally for enhancing partnerships and internally to facilitate prioritization and synergies. As this paper has shown, the World Bank Group works actively in many areas relevant to the SDGs, actually many more than covered here, but various evaluations have pointed to the importance of multi-sector integrated approaches that challenge countries and their partners to find new ways of working. The challenges that the SDGs aim to address, and the SDGs themselves, are complex, and solutions will have to be tailored to context, bring together multiple actors, and benefit from dynamic, constantly adjusted planning and execution that is informed by ongoing monitoring and evaluation.

Africa is currently experiencing the world's fastest urbanization rate at 3.5 percent annually-placing increasing pressure on resource-constrained local governments to maintain and improve livability standards of their cities. But simultaneously, an 'Information and Communication Technologies' (ICT) revolution has swept across the continent-as evidenced by vastly improved telecommunications and internet infrastructure, leapfrogging mobile communications penetration rates, and emergence of a successful homegrown IT applications industry. This report aims to: 1) synthesize the role currently played by ICT towards improved governance, management and accountability of urban service providers in Africa as well as other regions, 2) explore current ICT initiatives that are relevant to the World Bank's thematic concerns, 3) reconcile existing deficiencies/barriers towards potential for replication, and 4) develop a roadmap to render easy strategy implementation by project teams. Section one outlines evolving trends in urban governance and presents ICT as a potential tool in the environment of modern governance. Section two discusses the role of ICT in some of the Bank's core areas of urban focus, namely: local governance and economic development; intergovernmental fiscal relations and municipal finance; urban poverty and slum upgrading; urban planning, land and housing; urban environment and climate change; and water and sanitation service delivery. An analysis of fundamental ICT methodologies employed is discussed in section three. Section four, in conclusion, suggests an action-plan for enhancing ICT initiatives as a component of the Bank's lending activities.

International audience; Terahertz pulsed imaging has attracted considerable interest for revealing the stratigraphy and hidden features of art paintings. The reconstruction of the stratigraphy is based on the precise extraction of THz echo parameters from the reflected signals. Several historical panel paintings and wall paintings have been well studied by THz reflective imaging, in which the detailed stratigraphy has been successfully revealed. To our knowledge, however, the stratigraphy of oil paintings has not been clearly uncovered by THz imaging, since the paint layers in an oil painting on canvas, especially for the 16 th and 17 th century art works, are usually very thin (~10 m) in the THz regime. Therefore, in order to improve the performance of THz imaging, advanced signal-processing techniques with higher depth-resolution are still needed. In this study, THz reflective imaging is employed to reveal for the first time the detailed stratigraphy of a 17th century Italian oil painting on canvas. The paint layers on the supporting canvas are very thin in the THz regime, as the THz echoes corresponding to the stratigraphy totally overlap in the first cycle of the reflected THz signal. THz sparse deconvolution based on an iterative shrinkage algorithm is utilized to resolve the overlapping echoes. Based on the deconvolved signals, the detailed stratigraphy of this oil painting on canvas, including the varnish, pictorial, underdrawing, and ground layers, is successfully revealed. The THz C-and B-scans based on the THz deconvolved signals also enable us to reveal the features of each layer. Our results thus enhance the capability of terahertz imaging to perform detailed analysis and diagnostics of historical oil paintings on canvas with foreseen applications for the study of the artist's technique and for authentication.
