Transformations to achieve the Sustainable Development Goals Includes the SDG Index and Dashboards. Sustainable Development Report 2019

The Sustainable Development Report 2019 presents an updated SDG Index and Dashboards with a refined assessment of countries’ distance to SDG targets. The report has been successfully audited for the first time by the European Commission Joint Research Centre. New indicators have been included, primarily to refine the indicator selection on agriculture, diets, gender equality and freedom of speech. We have also added more metrics for international spillovers, including on fatal work accidents. A new website and data visualization tools are available (http://sustainabledevelopment.report). Once again, Nordic countries – Denmark, Sweden and Finland – top the SDG Index. Yet, even these countries face major challenges in implementing one or several SDGs. No country is on track for achieving all 17 goals with major performance gaps even in the top countries on SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), SDG 14 (Life Below Water) and SDG 15 (Life on Land). Income and wealth inequalities, as well as gaps in health and education outcomes by population groups also remain important policy challenges in developing and developed countries alike. The Sustainable Development Report 2019 generates seven major findings: 1. High-level political commitment to the SDGs is falling short of historic promises In September 2019, heads-of-states and governments will convene for the first time in person at the UN in New York to review progress on their promises made four years after the adoption of the 2030 Agenda. Yet, our in-depth analyses show that many have not taken the critical steps to implement the SDGs. Out of 43 countries surveyed on SDG implementation efforts, including all G20 countries and countries with a population greater than 100 million, 33 countries have endorsed the SDGs in official statements since January 1st, 2018. Yet in only 18 of them do central budget documents mention the SDGs. This gap between rhetoric and action must be closed. 2. The SDGs can be operationalized through six SDG Transformations SDG implementation can be organized along the following Transformations: 1. Education, Gender, and Inequality; 2. Health, Wellbeing, and Demography; 3. Energy Decarbonization and Sustainable Industry; 4. Sustainable Food, Land, Water, Oceans; 5. Sustainable Cities and Communities; and 6. Digital Revolution for Sustainable Development. The transformations respect strong interdependencies across the SDGs and can be operationalized by well-defined parts of governments in collaboration with civil society, business, and other stakeholders. They must be underpinned and guided by the principles of Leave No One Behind and Circularity and Decoupling of resource use from human wellbeing. 3. Trends on climate (SDG 13) and biodiversity (SDG 14 and SDG 15) are alarming On average, countries obtain their worst scores on SDG 13 (Climate Action), SDG 14 (Life Below Water) and SDG 15 (Life on Land). No country obtains a “green rating” (synonym of SDG achieved) on SDG 14 (Life Below Water). Trends on greenhouse gas emissions and, even more so, on threatened species are moving in the wrong direction. These findings are in line with the recent reports from the IPCC and IPBES on climate change mitigation and biodiversity protection, respectively. 4. Sustainable land-use and healthy diets require integrated agriculture, climate and health policy interventions Land use and food production are not meeting people’s needs. Agriculture destroys forests and biodiversity, squanders water and releases one-quarter of global greenhouse-gas emissions. In total, 78% of world nations for which data are available obtain a “red rating” (synonym of major SDG challenge) on sustainable nitrogen management; the highest number of “red” rating across all indicators included in the report. At the same time, one-third of food is wasted, 800 million people remain undernourished, 2 billion are deficient in micronutrients, and obesity is on the rise. New indicators on nations’ trophic level and yield gap closure highlight the depth of the challenge. Transformations towards sustainable landuse and food systems are required to balance efficient and resilient agriculture and forestry with biodiversity conservation and restoration as well as healthy diets

Bannai-Ito polynomials and dressing chains

Schur-Delsarte-Genin (SDG) maps and Bannai-Ito polynomials are studied. SDG maps are related to dressing chains determined by quadratic algebras. The Bannai-Ito polynomials and their kernel polynomials -- the complementary Bannai-Ito polynomials -- are shown to arise in the framework of the SDG maps.Comment: 15 pages; Section 2 is slightly modified and a few typos are correcte

Water and Nutrition: Harmonizing actions for the United Nations Decade of Action on Nutrition and the United Nations Water Action Decade

Progress for both SDG 2 and SDG 6 has been unsatisfactory, with several indicators worsening over time, including an increase in the number of undernourished, overweight and obese people, as well as rapid increases in the number of people at risk of severe water shortages. This lack of progress is exacerbated by climate change and growing regional and global inequities in food and water security, including access to good quality diets, leading to increased violation of the human rights to water and food. Reversing these trends will require a much greater effort on the part of water, food security, and nutrition communities, including stronger performances by the United Nations Decade of Action on Nutrition and the United Nations International Decade for Action on Water for Sustainable Development. To date, increased collaboration by these two landmark initiatives is lacking, as neither work program has systematically explored linkages or possibilities for joint interventions. Collaboration is especially imperative given the fundamental challenges that characterize the promotion of one priority over another. Without coordination across the water, food security, and nutrition communities, actions toward achieving SDG2 on zero hunger may contribute to further degradation of the world’s water resources and as such, further derail achievement of the UN Decade of Action on Water and SDG 6 on water and sanitation. Conversely, actions to enhance SDG 6 may well reduce progress on the UN Decade of Action on Nutrition and SDG 2. This paper reviews these challenges as part of a broader analysis of the complex web of pathways that link water, food security and nutrition outcomes. Climate change and the growing demand for water resources are also considered, given their central role in shaping future water and nutrition security. The main conclusions are presented as three recommendations focused on potential avenues to deal with the complexity of the water-nutrition nexus, and to optimize outcomes

Closed N=2 Strings: Picture-Changing, Hidden Symmetries and SDG Hierarchy

We study the action of picture-changing and spectral flow operators on a ground ring of ghost number zero operators in the chiral BRST cohomology of the closed N=2 string and describe an infinite set of symmetry charges acting on physical states. The transformations of physical string states are compared with symmetries of self-dual gravity which is the effective field theory of the closed N=2 string. We derive all infinitesimal symmetries of the self-dual gravity equations in 2+2 dimensional spacetime and introduce an infinite hierarchy of commuting flows on the moduli space of self-dual metrics. The dependence on moduli parameters can be recovered by solving the equations of the SDG hierarchy associated with an infinite set of abelian symmetries generated recursively from translations. These non-local abelian symmetries are shown to coincide with the hidden abelian string symmetries responsible for the vanishing of most scattering amplitudes. Therefore, N=2 string theory "predicts" not only self-dual gravity but also the SDG hierarchy.Comment: 41 pages, no figure

Links and trade-offs between fisheries and environmental protection in relation to the sustainable development goals in Thailand

The fisheries sector significantly contributes to global food security, nutrition, and livelihood of people. Its importance for economic benefits, healthy diets, and nutrition, and achieving sustainable food systems is highlighted by several Sustainable Development Goals (SDGs), i.e., SDG 1 (No Poverty), SDG 2 (Zero Hunger), and SDG 14 (Life Below Water). However, due to unprecedented population levels, the contribution of the fisheries sector to fulfills these roles is challenging, particularly given additional concerns regarding environmental well-being and sustainability. From this perspective, this study aims to identify the links and trade-offs between the development of this sector and the environmental sustainability in Thailand via a critical analysis of their trends, current ecological impacts, and more importantly, their contributions to several individual SDGs. A time-series of Thailand's fisheries production from 1995 to 2015 indicates a recent reduction from around 3.0 million tons in 1995 to 1.5 million tons in 2015 of wild fish and shellfish from marine and freshwater habitats. The maximum sustainable yield of these species has been exceeded. Conversely, Thailand's aquaculture production has continued to grow over the last decade, resulting in a reduction of mangrove forest area, wild fish stocks, and water quality. While capture fisheries and aquaculture production significantly contribute to several SDG targets, there are potential trade-offs between their development and the achievement of SDGs within the planet dimension, i.e., SDG 6 (Clean Water and Sanitation), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), SDG 14, and SDG 15 (Life on Land). On the one hand, the mitigation of overfishing will be beneficial for the targets of SDG 14, leading to more sustainable resource management. On the other hand, it might cause a decrease in the volume of marine catches and economic and social profits. We conclude that the SDGs can serve as a framework for both policymakers and industrial workers to monitor and compromise on regulations that will optimize productivity in the context of sustainable development

Workshop report : Earth and Environmental Science for Sustainable Development (Nairobi, March 2017)

This report describes the outcomes of a two-day interactive workshop in Nairobi (Kenya), conducted in March 2017. We gathered 32 delegates from 22 organisations in Kenya to determine sustainable development priorities and consider the role of Earth and environmental science in addressing these. Delegates came from diverse disciplines (e.g., geology, agriculture, geography, hydrology, ecology) and sectors (e.g., academia, commercial, civil society, government). Using the UN Sustainable Development Goals (SDGs) as a reference tool, participants identified primary development challenges and their research and data needs to help address these. Key themes included the food-water-energy nexus, clean water, and natural resources (minerals). Participants co-designed a set of draft science-for-development projects relating to these themes. BGS are using this information, together with the results of additional workshop activities, to inform the development of collaborative science-for-development activities in eastern Africa as part of our commitment to Official Development Assistance (ODA) in the region. We will further develop specific project ideas, using information gathered at this workshop, with appropriate regional and international partners. Information from this workshop provides supporting evidence of expressed development need and stakeholder expertise in eastern Africa. This information will guide future project applications to the Global Challenges Research Fund, and other appropriate research and innovation funding sources. Key Results and Conclusions Small group discussions and group voting generated a collective ranking of SDG priorities. Participants also reflected on where they believe Earth and environmental science can make the greatest contribution to development impact. These rankings were: Overall SDG ranking (Eastern Africa) based on summing of small groups votes: 1. Clean Water and Sanitation (SDG 6) 2. No Poverty (SDG 1) 3. Zero Hunger (SDG 2) 4. Good Health and Wellbeing (SDG 3) 5. Quality Education (SDG 4) Role for Earth and environmental science rankings: 1. Clean Water and Sanitation (SDG 6) 2. Climate Action (SDG 13) 3. Life on Land (SDG 15) 4. Affordable and Clean Energy (SDG 7) 5. Zero Hunger (SDG 2) Group discussions suggested that interconnectedness of SDGs and basic (immediate) development needs were likely to influence the prioritisation process. For example, participants noted that ending poverty (SDG 1), ending hunger (SDG 2) and ensuring access to clean water and sanitation (SDG 6) would underpin progress in many of the other SDGs. We used these rankings to establish three thematic working groups, with each tasked to identify specific challenges, research priorities, information needs and potential projects. Groups were: Food-water-energy nexus. This group identified geographic areas of interest, and considered crosscutting issues (data, cultural and political barriers, partnerships, lessons learned, and capacity building). Clean water and sanitation. This group discussed water availability mapping, enhanced water policy/governance/management, improved catchment management, data gaps, and applied research and training activities. Natural resources (minerals). This group identified activities relating to a Mombasa to Kisumu resource corridor, and artisanal and small-scale mining activities. Developing these activities will require effective science-for-development partnerships. Partnership characteristics of greatest importance to Kenyan participants were (i) sharing of project outputs, (ii) sharing of data, (iii) being treated as equals by other members of the partnership, and (iv) access to training and capacity building

Sustainable Survival for adolescents living with HIV: do SDG-aligned provisions reduce potential mortality risk?

INTRODUCTION: The Sustainable Development Goals (SDGs) present a groundbreaking global development agenda to protect the most vulnerable. Adolescents living with HIV in Sub-Saharan Africa continue to experience extreme health vulnerabilities, but we know little about the impacts of SDG-aligned provisions on their health. This study tests associations of provisions aligned with five SDGs with potential mortality risks. METHODS: Clinical and interview data were gathered from N = 1060 adolescents living with HIV in rural and urban South Africa in 2014 to 2015. All ART-initiated adolescents from 53 government health facilities were identified, and traced in their communities to include those defaulting and lost-to-follow-up. Potential mortality risk was assessed as either: viral suppression failure (1000+ copies/ml) using patient file records, or adolescent self-report of diagnosed but untreated tuberculosis or symptomatic pulmonary tuberculosis. SDG-aligned provisions were measured through adolescent interviews. Provisions aligned with SDGs 1&2 (no poverty and zero hunger) were operationalized as access to basic necessities, social protection and food security; An SDG 3-aligned provision (ensure healthy lives) was having a healthy primary caregiver; An SDG 8-aligned provision (employment for all) was employment of a household member; An SDG 16-aligned provision (protection from violence) was protection from physical, sexual or emotional abuse. Research partners included the South African national government, UNICEF and Pediatric and Adolescent Treatment for Africa. RESULTS: 20.8% of adolescents living with HIV had potential mortality risk - i.e. viral suppression failure, symptomatic untreated TB, or both. All SDG-aligned provisions were significantly associated with reduced potential mortality risk: SDG 1&2 (OR 0.599 CI 0.361 to 0.994); SDG 3 (OR 0.577 CI 0.411 to 0.808); SDG 8 (OR 0.602 CI 0.440 to 0.823) and SDG 16 (OR 0.686 CI 0.505 to 0.933). Access to multiple SDG-aligned provisions showed a strongly graded reduction in potential mortality risk: Among adolescents living with HIV, potential mortality risk was 38.5% with access to no SDG-aligned provisions, and 9.3% with access to all four. CONCLUSIONS: SDG-aligned provisions across a range of SDGs were associated with reduced potential mortality risk among adolescents living with HIV. Access to multiple provisions has the potential to substantially improve survival, suggesting the value of connecting and combining SDGs in our response to paediatric and adolescent HIV

Stable Delaunay Graphs

Let $P$ be a set of $n$ points in $\mathrm{R}^2$, and let $\mathrm{DT}(P)$ denote its Euclidean Delaunay triangulation. We introduce the notion of an edge of $\mathrm{DT}(P)$ being {\it stable}. Defined in terms of a parameter $\alpha>0$, a Delaunay edge $pq$ is called $\alpha$-stable, if the (equal) angles at which $p$ and $q$ see the corresponding Voronoi edge $e_{pq}$ are at least $\alpha$. A subgraph $G$ of $\mathrm{DT}(P)$ is called {\it $(c\alpha, \alpha)$-stable Delaunay graph} ($\mathrm{SDG}$ in short), for some constant $c \ge 1$, if every edge in $G$ is $\alpha$-stable and every $c\alpha$-stable of $\mathrm{DT}(P)$ is in $G$. We show that if an edge is stable in the Euclidean Delaunay triangulation of $P$, then it is also a stable edge, though for a different value of $\alpha$, in the Delaunay triangulation of $P$ under any convex distance function that is sufficiently close to the Euclidean norm, and vice-versa. In particular, a $6\alpha$-stable edge in $\mathrm{DT}(P)$ is $\alpha$-stable in the Delaunay triangulation under the distance function induced by a regular $k$-gon for $k \ge 2\pi/\alpha$, and vice-versa. Exploiting this relationship and the analysis in~\cite{polydel}, we present a linear-size kinetic data structure (KDS) for maintaining an $(8\alpha,\alpha)$-$\mathrm{SDG}$ as the points of $P$ move. If the points move along algebraic trajectories of bounded degree, the KDS processes nearly quadratic events during the motion, each of which can processed in $O(\log n)$ time. Finally, we show that a number of useful properties of $\mathrm{DT}(P)$ are retained by $\mathrm{SDG}$ of $P$.Comment: This is a revision of the paper arXiv:1104.0622 presented in SoCG 2010. The revised analysis relies on results reported in the companion paper arXiv:1404.485
