Resumen

In India, most of the streets within the habitations are illuminated from evening until morning, averaging roughly 12 hours per day. Throughout the night, some streets may not have automobiles or even pedestrians travelling through them which results in power loss. In addition, the number of vehicles on the road is increasing every day, and traditional traffic management is still in use, road accidents are one of our country's key issues. Many important lives are lost as a result of these accidents, which occur when emergency assistance is unavailable. So, our proposed solution for this problem is that we are designing a model that first detects the traffic and examine then based on situation it controls the lightening system and send traffic intensity data to internet hour wise. For accident detection we used the SOS button to get help immediately and crewman get the exact location of accident. According to the results obtained from the proposed method, energy usage is greatly reduced, and we can receive a very quick alarm when something unpleasant occurs.

Resumen

Abstract: Wise city management, good road management is one of the most important things. Traffic congestion can be effectively controlled, provided that the number of vehicles passing through a traffic junction can be determined in advance. The proposed approach introduces a framework, which has the potential to continuously transmit traffic and generate alarms in the event of a major traffic congestion at the Sangli control station or in similar Indian cities. The number of vehicles passing through the area well before the required road junction can be estimated using the help of image processing techniques. In addition, monitoring information can be shared with a remote control centre near the city via the Internet. The tests performed show the effectiveness of this Internet-based technology (IoT) technology. Keywords: Traffic Volume Estimation, Genetic Algorithm, Wireless sensor network, Vehicle detection, Intelligent Traffic Signal Controller.

Our current Healthcare system has multiple problems and it is widely perceived that it is not able to provide quality affordable healthcare to all Americans; millions of Americans are without Health Insurance. The Affordable Care Act (ACA) was signed into law to achieve goal of 'quality affordable care for all American'. The ACA has focus on Individual Health Insurance and the provision of Health Exchange Marketplaces to find and purchase Health Insurance. Disruptive Innovation is a phenomenon in which a new entrant company disrupts the existing established company. As ACA and Health Exchanges have provided level playing field for all companies - new entrants and established - will this lead to disruption of Healthcare? Disruptive Innovations is analyzed from System Approach point of view. Disruption is not limited to two companies; Disruptor System disrupts the existing system including incumbent company. Disruption will be spearheaded by new entrant Disruptor Company and disruption will take place at system level. The existing Healthcare System and Possible Disruptor Systems are defined and investigated. Relative advantage and disadvantages to these two systems with regard to ACA regulations are analyzed. Elements of the healthcare disruptor system are analyzed and information present in the public domain about Health Exchange enrolment after the end of first enrollment seasons is studied to find out who could be possible disruptor and whether disruptor system formation has started.

What if an open-source software showed what is the total cost of ownership of consumer goods, including emissions over time? Consumers' decision making is often price sensitive. An assessment of twelve mobility units' classes 1 to 5 at market price, their operation expenses, resale prices, and emissions show the real cost for the final consumer. Light-duty vehicles from the world's largest vehicle manufacturers: Toyota, Volkswagen, Honda, Hyundai, Chevrolet, Nissan, and tiny Tesla, from three continents are compared. Gasoline, hybrid, electric, and hydrogen-fueled powertrains performance over 12 years demonstrate how non-fossil fueled units offset their higher upfront price compared to their gasoline counterparts in 6 years. A micromobility option, a bicycle, is graphed against engine units. The Paris Agreement signed by 175 countries suggests a carbon tax which is levied in 29 countries. Such tax is forecasted in the non-signee of the Agreement, and number two highest polluter in the world, the United States. Three scenarios were calculated: at zero, fifteen and forty USD per Metric ton oil equivalent, as a path for massive production to account for environmental externalities. Life Cycle Analysis, Circular Economy and Smart Capitalism are articulated as solutions aiming to NetZero transportation targeting the segment responsible for the most GHG emissions in the industry, mid-sized cars. Collaboration and inclusive negotiation informed by consistent information are presented as means to lessen the gender gap and unite decision-makers to reach the Sustainability Development Goals. A systems-level approach is proposed in the form of private-public partnerships and global data sharing to scale and implement existing technologies. Cleaning the power grid by producing and storing renewable energy, implementing carbon capture, usage, and storage, and producing green hydrogen from electrolysis are pointed out as central global strategies to stop Climate Change.

Light plays a significant role in urbanization throughout human history. And as the number of people living in the cities has already exceeded half of the world's population, people are facing many challenges like poor infrastructure, social problems, etc. To overcome the burgeoning populations, the lighting innovation is necessary. This thesis presents a solution to the challenges of a light and caring city. We present a lighting system that integrates design strategy, system architecture, and product design. The thesis begins with exploratory research at the intersection of the keywords, light and caring city. We discuss six support roles of light in daily life and twenty features of the caring cities from case studies. We dive into issues of wellbeing and work-life balance with the hypothesis that there lies an opportunity to make a meaningful impact with innovative lighting.
To get the holistic view of the challenge, primary and secondary research were conducted to understand user needs before developing the design concepts of the lighting product or service. The design iteration uncovered feedback from users and professionals in the lighting industry, revealing valuable insights and a critical puzzle piece that the industry still struggles to answer: how can personalized lighting support citizens' activities in shared spaces? We believe our solution will make a significant impact to people in their daily lives. The thesis develops a 'smart lighting' solution to personalize and support daily activities, as envisioned for futuristic caring cities. Using a co-working space as the concept demonstration, the thesis introduces the Intelligent Connected Lighting System and a five-layer ruleset. This ruleset integrates a human's biological clock, weather effects, shared space occupancy, activities performed, and custom settings made by users.
Our system automatically adjusts luminaires to meet user needs in real-time. Also, to support the flexibility of the system, two additional intelligent lamps were designed with installation suggestions.

Resumen

The primary purpose of this research was to develop new methodologies to process and analyze large amount of topographic data from airborne LIDAR (light detection and ranging) survey. This research developed a suite of algorithms to resample dense clouds of point data from LIDAR survey, cut the large data set into smaller tiles, and filtered data to remove points from non-ground surface features such as vegetations, buildings, and vehicles. These algorithms were implemented on the PC platform using C++. The test results showed that the developed application software package based on these algorithms worked well. This application software package provided users an efficient way to retrieve, analyze, and display large volumes of LIDAR survey data, and to extract topographic information.

Resumen

It is not uncommon for enterprises today to be faced with the demand to integrate and incor- porate many different and possibly heterogeneous systems which are generally independently designed and developed, to allow seamless access. In effect, the integration of these systems results in one large whole system that must be able, at the same time, to maintain the local autonomy and to continue working as an independent entity. This problem has introduced a new distributed architecture called federated systems. The most challenging issue in federated systems is to find answers for the question of how to efficiently cooperate while preserving their autonomous characteristic, especially the security autonomy. This thesis intends to address this issue. The thesis reviews the evolution of the concept of federated systems and discusses the organisational characteristics as well as remaining security issues with the existing approaches. The thesis examines how delegation can be used as means to achieve better security, especially authorisation while maintaining autonomy for the participating member of the federation. A delegation taxonomy is proposed as one of the main contributions. The major contribution of this thesis is to study and design a mechanism to support dele- gation within and between multiple security domains with constraint management capability. A novel delegation framework is proposed including two modules: Delegation Constraint Man- agement module and Policy Management module. The first module is designed to effectively create, track and manage delegation constraints, especially for delegation processes which require re-delegation (indirect delegation). The first module employs two algorithms to trace the root authority of a delegation constraint chain and to prevent the potential conflict when creating a delegation constraint chain if necessary. The first module is designed for conflict prevention not conflict resolution. The second module is designed to support the first module via the policy comparison capability. The major function of this module is to provide the delegation framework the capability to compare policies and constraints (written under the format of a policy). The module is an extension of Lin et al.'s work on policy filtering and policy analysis. Throughout the thesis, some case studies are used as examples to illustrate the discussed concepts. These two modules are designed to capture one of the most important aspects of the delegation process: the relationships between the delegation transactions and the involved constraints, which are not very well addressed by the existing approaches. This contribution is significant because the relationships provide information to keep track and en- force the involved delegation constraints and, therefore, play a vital role in maintaining and enforcing security for transactions across multiple security domains.

Resumen

The quest for new artificial structures and materials uncovers novel new light-matter interactions, and intriguing physical phenomena. Since the late 80’s purely dielectric materials have been structured, at the wavelength-scale, to develop photonic crystals and photonic crystal fibres. Recently, also the modulation of gain and losses came into play. The new platform based on complex refractive index materials, combining index and gain-loss modulations, opens the door towards new physical concepts and novel applications. One of these fascinating new insights is the realization of classical analogues of quantum systems described by non-Hermitian Hamiltonians, where the complex refractive index plays the role of a complex optical potential. Thus, by carefully combining the real and imaginary parts of the refractive index; it is possible to observe unusual features that cannot be attained in classical Hermitian systems. In particular, non-Hermitian PT-symmetric systems, invariant under the parity and time-reversal symmetries, may support nidirectional mode coupling which is at the basis of novel ideas and applications such as unidirectional invisibility, single mode microlasers or super-sensitive sensors just to name a few. Non-Hermitian photonics has overturned the conventional negative perception of losses, and offers new possibilities to utilize the gain and loss for steering optical processes. The aim of this thesis is to provide new insights into the wave dynamics in this new artificial complex media since a flexible wave control may be essential to design novel technological devices. The work has a double scope: to propose and develop new concepts in fundamental science framework; and to provide technological studies for direct applications in actual and ubiquitous devices such as broad area semiconductor lasers. In this sense, the main contribution is a novel approach to manipulate the light flow using non-Hermitian systems for light localization and enhancement, and for the control of the flow of light following arbitrary vector fields and corresponding applications to photonic devices. We apply the new fundamental concept of local PT-symmetry to one and two dimensions PT-axisymmetric configurations to obtain highly localized fields at selected position or area. Further, we extend and generalize the idea of local PT-symmetry to design systems able to control the flow of light. We develop a mathematical framework to design such 2D (or higher dimensional) complex structured material for any arbitrary vector field and desired topology, referred as a local Hilbert transform which relates the real and imaginary parts of the complex refractive index. The theory of such directionality field is tested on random, periodic, quasi-periodic and localized patterns to generate arbitrary field flows in the form of a sink, vortices or circular channel flows, both in linear and nonlinear systems. Moreover, we investigate non-Hermitian structures for technological applications. We consider 2D periodic lattices, with simultaneous transverse and longitudinal PT-symmetry to obtain self-collimated beams, useful for example in integrated optics. We also propose different schemes of index and gain/loss modulations to enhance the stability of broad area semiconductor (BAS) devices. Besides, we show how: (i) the introduction of spatiotemporal modulation on the pump of vertical-external-cavity surface-emitting lasers (VECSELs) with a simple flat mirror configuration, may stabilize its emission; (ii) in phase modulations of index and gain-loss profiles stabilizes the emission from BAS lasers and amplifiers, a proposal relying on the suppression of modulation instabilities using dispersion management; (iii) PT-axisymmetry applied either to BAS lasers or VCSELs renders these lasers into bright and narrow laser sources.
La recerca de nous materials i estructures artificials revela nous mecanisme d’interacció llum-matèria i fenòmens físics inesperats. A finals dels 80, es desenvolupen els primers materials estructurats a escala de la longitud d'ona, cristalls fotònics i fibres de cristall fotònic, utilitzant materials purament dielèctrics. Més recentment, s’afegeixen també modulacions del guany òptic i pèrdues (absorció). Els nous materials artificials estructurats, que combinen modulacions d'índex i de guanys i pèrdues, caracteritzats per tenir índexs de refracció complexos, obren les portes a noves idees físiques i futures aplicacions. Aquests sistemes permeten també realitzar sistemes clàssics anàlegs als quàntics amb Hamiltonians no hermítics, on l’índex de refracció complex juga el paper de potencial òptic complex. Amb un dissenyat acurat del potencial òptic s’assoleixen característiques impossibles en sistemes hermítics clàssics. En particular, els sistemes no hermítics invariants sota la simetria de Paritat i d’inversió Temporal, denominats sistemes amb simetria PT, permeten acoblaments unidireccionals entre modes, que són la base d’idees i aplicacions sorprenents com: la invisibilitat unidireccional, microlàsers monomode, super-sensors,... La fotònica no hermítica canvia la percepció negativa que es tenia de l’absorció en dispositius òptics, ja que permet utilitzar de forma avantatjosa no només el guany òptic sinó també les pèrdues. L'objectiu d'aquesta tesi és aprofundir en la propagació dones a través de sistemes òptics no hermítics, ja que el seu control pot ser essencial per al disseny de nous dispositius. Així, la tesi té un doble objectiu: l’estudi d’aspectes fonamentals de la fotònica no hermítica i la seva aplicació directa en la millora de dispositius tecnològics ja existents (com en làsers de semiconductors) o innovadors. La principal aportació és el desenvolupament d’un nou mecanisme per al control i manipulació del flux de la llum, que permet: localitzar i concentrar la llum en un punt desitjat, o controlar el flux de llum seguint un camp vectorial arbitrari; i la proposta d’aplicacions a dispositius fotònics. Primer es formula un nou concepte fonamental: els sistemes amb simetria PT local (amb configuracions PT-axisimètriques en una i dues dimensions) per obtenir camps molt localitzats en una posició o àrea determinada. Després, es generalitza la idea per dissenyar camps capaços de controlar el flux de la llum. Es desenvolupa una eina matemàtica que anomenen transformació local d’Hilbert, per dissenyar aquest tipus de sistemes estructurats en dues (o més) dimensions, per aconseguir que el flux de llum segueixi qualsevol camp vectorial arbitrari i topologia desitjada. Aquesta transformació relaciona la part real i imaginària de l'índex de refracció complex. Es comprova el funcionament del potencials generats seguint aquest procediment, utilitzant inicialment diferents patrons: aleatoris, periòdics, quasi-periòdics o bé localitzats. En tots els cassos es demostra que és possible generar fluxos en forma radial, vòrtex o fluxos circulars, tant en sistemes lineals com no lineals. Pel que fa a aplicacions tecnològiques, es consideren xarxes periòdiques en dues dimensions, amb simetria PT transversal i longitudinal per obtenir feixos auto-col·limats, útils, per exemple, en òptica integrada. També s’estudien diferents esquemes per millorar l'estabilitat de fonts de llum de semiconductors d'àrea ampla (BAS). Es demostra que: (i) la modulació espacio-temporal del bombeig estabilitza emissors làser de superfície amb cavitat externa vertical (VECSEL) amb configuració de mirall pla; (ii) les modulacions d'índex i de guany i pèrdua poden suprimir les inestabilitats de modulació mitjançant el control de dispersió en làsers i amplificadors BAS amb; (iii) la simetria PT aplicada als làsers BAS o els VCSEL modula el feix

Resumen

This thesis project investigates the state-of-the-art in traffic management "Green Light Optimal Speed Advisory (GLOSA)" for vehicles in a smart city. GLOSA utilizes infrastructure and vehicles communication through using current signal plan settings and updated vehicular information in order to influence the intersection approach speeds. The project involves traffic microscopic simulations for a mixed traffic environment of conventional and automated vehicles (AVs) both connected to the intersection control and guided by a speed advisory traffic management system. Among the project goals is to assess the effects on traffic performance when human drivers comply to the speed advice. The GLOSA management approach is accessed for its potential to improve traffic efficiency in a full market penetration of connected AVs with absolute compliance. The project also aims to determine the possible outcome resulting from enhancing the AVs capabilities such as implementing short time headways between vehicles in the future. The best traffic performance results achieved by operating GLOSA goes for connected AVs with the lowest simulated time headway (0.3 sec). The waiting time reduction reaches 95% and trip delay lessens to 88 %.

The unrelenting increase in oil use by the U.S. light-duty vehicle (LDV) fleet presents an extremely challenging energy and environmental problem. A variety of propulsion technologies and fuels have the promise to reduce petroleum use and greenhouse gas (GHG) emissions from motor vehicles. Previous work in this domain has compared individual vehicle or fuel alternatives. The aim of this research was to deepen the understanding of the likely scale and timing of the fleet-wide impact of emerging technologies. A model of the light-duty vehicle fleet showed that fuel consumption of mainstream gasoline internal combustion engine (ICE) technology vehicles will determine the trajectory of fleet fuel use and GHG emissions over the next two decades. Using vehicle simulations and historical data, the trade-off between vehicle performance, size and fuel consumption was quantified. It was shown that up to 26 percent reduction in future LDV fuel use is possible with mainstream gasoline ICE vehicles alone if emphasis of vehicle technology is on reducing fuel consumption rather than improving performance. Addressing this vehicle performance-size-fuel consumption trade-off should be the priority for policymakers. By considering both supply and demand side constraints on building up vehicle production rates, three plausible scenarios of advanced vehicle market penetration were developed. Due to strong competition from mainstream gasoline vehicles and high initial cost, market penetration rates of diesels and gasoline hybrids in the U.S. are likely to be slow. As a result, diesels and gasoline hybrids have only a modest, though growing potential for reducing fleet fuel use before 2025. In general, the time-scales to impact of new technologies are twenty to twenty-five years.
(cont.) Integrating vehicle and fuel scenarios showed that measures which reduce greenhouse gas emissions also reduce petroleum consumption, but the converse is not necessarily true. Policy efforts therefore should be focused on measures that improve both energy security and carbon emissions at the same time. While up to 35 percent reduction in fleet GHG emissions from a No Change scenario is possible by 2035, the magnitude of changes required to achieve these reductions are daunting, as all of the current trends run counter to the changes required.

Resumen

Without the informal economy, there would be no waste recycling in most Asian cities. In many Asian countries, waste management systems are underdeveloped, with the informal economy dominating the processes of waste collection, sorting and recycling. In this short report, we present preliminary findings from our survey of 34 waste pickers in Bangkok. The report sheds light on their working conditions, health risks, gendered dimensions and the challenges they face in waste recycling.

Resumen

Commercial agriculture has come under increasing pressure to reduce nitrogen fertilizer inputs in order to minimize potential nonpoint source pollution of ground and surface waters. This has resulted in increased interest in site specific fertilizer management. One way to solve pollution problems would be to determine crop nutrient needs in real time, using remote detection, and regulating fertilizer dispensed by an applicator. By detecting actual plant needs, only the additional nitrogen necessary to optimize production would be supplied. This research aimed to develop techniques for real time assessment of nitrogen status of corn using a mobile sensor with the potential to regulate nitrogen application based on data from that sensor. Specifically, the research first attempted to determine the system parameters necessary to optimize reflectance spectra of corn plants as a function of growth stage, chlorophyll and nitrogen status. In addition to that, an adaptable, multispectral sensor and the signal processing algorithm to provide real time, in-field assessment of corn nitrogen status was developed. Spectral characteristics of corn leaves reflectance were investigated in order to estimate the nitrogen status of the plants, using a commercial laboratory spectrometer. Statistical models relating leaf N and reflectance spectra were developed for both greenhouse and field plots. A basis was established for assessing nitrogen status using spectral reflectance from plant canopies. The combined effect of variety and N treatment was studied by measuring the reflectance of three varieties of different leaf characteristic color and five different N treatments. The variety effect on the reflectance at 552 nm was not significant (a = 0.01), while canonical discriminant analysis showed promising results for distinguishing different variety and N treatment, using spectral reflectance. Ambient illumination was found inappropriate for reliable, one-beam spectral reflectance measurement of the plants canopy due to the strong spectral lines of sunlight. Therefore, artificial light was consequently used. For in-field N status measurement, a dark chamber was constructed, to include the sensor, along with artificial illumination. Two different approaches were tested (i) use of spatially scattered artificial light, and (ii) use of collimated artificial light beam. It was found that the collimated beam along with a proper design of the sensor-beam geometry yielded the best results in terms of reducing the noise due to variable background, and maintaining the same distance from the sensor to the sample point of the canopy. A multispectral sensor assembly, based on a linear variable filter was designed, constructed and tested. The sensor assembly combined two sensors to cover the range of 400 to 1100 nm, a mounting frame, and a field data acquisition system. Using the mobile dark chamber and the developed sensor, as well as an off-the-shelf sensor, in- field nitrogen status of the plants canopy was measured. Statistical analysis of the acquired in-field data showed that the nitrogen status of the com leaves can be predicted with a SEP (Standard Error of Prediction) of 0.27%. The stage of maturity of the crop affected the relationship between the reflectance spectrum and the nitrogen status of the leaves. Specifically, the best prediction results were obtained when a separate model was used for each maturity stage. In-field assessment of the nitrogen status of corn leaves was successfully carried out by non contact measurement of the reflectance spectrum. This technology is now mature to be incorporated in field implements for on-line control of fertilizer application.

Case study from male and female Arabica coffee farmers in Vietnam. World Agroforestry, 2021. http://dx.doi.org/10.5716/wp21025.pdf.

Resumen

Estimates of carbon sequestration for timber trees is well documented, while fruit trees are understudied. The few existing estimates indicate that fruit trees and fertiliser management on them, can substantially sequester carbon in coffee monocultures, albeit unlikely to the same extent as timber trees. A carbon investor may thus favour timber. In this light, as programs for planting billions and trillion trees are launched “to save the climate”, a wide range of gender, social, justice and environmental concerns are voiced. To challenge the mitigation perspective, we contrasted two hypothetical tree planting strategies: a mitigation (carbon finance) perspective and a livelihoods-centred (local) perspective and explored what a rapid, gender and social inclusion-oriented livelihoods perspective could bring to the process of tree selection. The survey documents indigenous knowledge of trees’ potential (dis)benefits in coffee agroforestry systems among 106 female and male arabica-growers in northwest Vietnam. The results display many similarities between women and men in term of perceived benefits from trees. Women and men prioritized trees based on their economic benefits, impacts on coffee production and improved soil fertility. However, in determining the preferred species, women considered more factors, including consequences for pest and disease (on host tree or coffee), microclimate regulation and shade provision. These findings resemble those by others from the same region and demonstrate that consulting both women and men can result in a more diverse shortlist of potential trees for agroforestry/afforestation that reflect both genders’ economic and labour contributions to the household. Furthermore, tree planting projects would benefit from seeking collaboration for bundled ecosystem services, rather than merely from carbon finance. Conversely, carbon investors can rely on farmers’ preferences and rest assured that they also contribute to sequestering carbon.

Resumen

Mastitis, an inflammatory response of the mammary tissue to invading pathogenic bacteria, is the largest health problem in the dairy industry and is responsible for multibillion dollar economic losses. E. coli are a leading cause of acute mastitis in dairy animals worldwide and certainly in Israel and North America. The species E. coli comprises a highly heterogeneous group of pathogens, some of which are commensal residents of the gut, infecting the mammary gland after contamination of the teat skin from the environment. As compared to other gut microflora, mammary pathogenic E. coli (MPEC) may have undergone evolutionary adaptations that improve their fitness for colonization of the unique and varied environmental niches found within the mammary gland. These niches include competing microbes already present or accompanying the new colonizer, soluble and cellular antimicrobials in milk, and the innate immune response elicited by mammary cells and recruited immune cells. However, to date, no specific virulence factors have been identified in E. coli isolates associated with mastitis. The original overall research objective of this application was to develop a genome-wide, transposon-tagged mutant collection of MPEC strain P4 and to use this technology to identify E. coli genes that are specifically involved in mammary virulence and pathogenicity. In the course of the project we decided to take an alternative genome-wide approach and to use whole genomes bioinformatics analysis. Using genome sequencing and analysis of six MPEC strains, our studies have shown that type VI secretion system (T6SS) gene clusters were present in all these strains. Furthermore, using unbiased screening of MPEC strains for reduced colonization, fitness and virulence in the murine mastitis model, we have identified in MPEC P4-NR a new pathogenicity island (PAI-1) encoding the core components of T6SS and its hallmark effectors Hcp, VgrG and Rhs. Next, we have shown that specific deletions of T6SS genes reduced colonization, fitness and virulence in lactating mouse mammary glands. Our long-term goal is to understand the molecular mechanisms of host-pathogen interactions in the mammary gland and to relate these mechanisms to disease processes and pathogenesis. We have been able to achieve our research objectives to identify E. coli genes that are specifically involved in mammary virulence and pathogenicity. The project elucidated a new basic concept in host pathogen interaction of MPEC, which for the best of our knowledge was never described or investigated before. This research will help us to shed new light on principles behind the infection strategy of MPEC. The new targets now enable prevalence and epidemiology studies of T6SS in field strains of MPEC which might unveil new geographic, management and ecological risk factors. These will contribute to development of new approaches to treat and prevent mastitis by MPEC and perhaps other mammary pathogens. The use of antibiotics in farm animals and specifically to treat mastitis is gradually precluded and thus new treatment and prevention strategies are needed. Effective mastitis vaccines are currently not available, structural components and effectors of T6SS might be new targets for the development of novel vaccines and therapeutics.

Resumen

The COVID-19 pandemic has been tremendously difficult for many people across the globe. What was initially viewed as a health crisis affected societies to their core, many of which were already grappling with the devastating effects of climate change, as well as other challenges such as political instability and conflict. While each of these crises has its own identifiable causes, the increasingly interconnected nature of our world means that these shocks or hazards and the knock-on effects from them cannot be viewed in isolation. Indeed, the number of record-breaking disasters witnessed over the past years and their cascading effects across sectors and borders have illuminated those interconnections as never before. Similarly, interconnections became very visible whenCOVID-19 started to spread around the globe. The unfolding pandemic prompted a range of policy measures to limit the spread of the virus and avoid health systems becoming overwhelmed. Yet the effects of these measures, including stay-at-ho-me orders and shutdown of public life, while highly important to prevent health system collapse and reduce COVID-19 fatalities, hit the most vulnerable the hardest. Underlying vulnerabilities such as poverty, precarious jobs in the informal economy, lack of access to education and, structural gender biases were exacerbated by the pandemic. This report sheds light on the complexity of risks in a highly interconnected world, and present lessons for risk management. Focusing on COVID-19, it shows how, through the interconnectedness of societies and the underlying vulnerabilities within them, the direct and indirect impacts of the pandemic have revealed the systemic nature of risk. Through a case study approach, it demonstrates how the pandemic triggered a multitude of impacts far beyond the direct health crisis, including joblessness, debt, civil and domestic violence and the derailment of their children’s education, among many others. In many locations, women suffered disproportionately, whether as a result of bias in employment patterns or other pre-existing gender biases in society. Drawing on insights from different case studies across the world, this report also offers lessons from the pandemic for understanding risk more systemically, and presents recommendations for risk management moving forward.
