Climate hazards pose increasing threats to development outcomes across the world’s coastal regions by impacting infrastructure service delivery. Using a high-resolution dataset of 8.2 million households in Bangladesh’s coastal zone, we assess the extent to which infrastructure service disruptions induced by flood, cyclone and erosion hazards can thwart progress towards the Sustainable Development Goals (SDGs). Results show that climate hazards potentially threaten infrastructure service access to all households, with the poorest being disproportionately threatened in 69% of coastal subdistricts. Targeting adaptation to these climatic threats in one-third (33%) of the most vulnerable areas could help to safeguard 50–85% of achieved progress towards SDG 3, 4, 7, 8 and 13 indicators. These findings illustrate the potential of geospatial climate risk analyses, which incorporate direct household exposure and essential service access. Such high-resolution analyses are becoming feasible even in data-scarce parts of the world, helping decision-makers target and prioritize pro-poor development.

The energy sector is the largest emitter of greenhouse gas emissions, accounting for 37% of the world's combined emissions, and plays a key role in achieving the Sustainable Development Goals. However, there is no systematic means for planners and practitioners to integrate climate considerations throughout the lifecycle of energy infrastructure projects. Using a thematic document analysis, we provide a comprehensive list of activities related to climate mitigation and adaptation which can be systematically mainstreamed into the energy sector project lifecycle to support a range of sustainable development outcomes. Two renewable energy projects were used to integrate the results into a practical context and demonstrate the range of potential SDG target synergies. The case studies demonstrate the varied means by which climate action can be integrated through mainstreaming in project lifecycle stages, holistically achieving wider SDG impacts. This work provides a practical means to maximise progress within the framework of climate-compatible development.

With each IPCC report, the science basis around climate change increases extensively in terms of scope, depth, and complexity. In converting this knowledge into societal climate action, research organisations face the challenge of reforming the ways they structure themselves, generate solutions, and communicate scientific findings to stakeholders. Here we present a mission-driven approach to guide those efforts.

Scaling up national climate adaptation under the Paris Agreement is critical not only to reduce risk, but also to contribute to a nation's development. Traditional adaptation assessments are aimed at evaluating adaptation to cost-effectively reduce risk and do not capture the far-reaching benefits of adaptation in the context of devel-opment and the global Sustainable Development Goals (SDGs). By grounding adaptation planning in an SDG vision, we propose and demonstrate a methodological process that for the first time allows national decision -makers to: i) quantify the adaptation that is needed to safeguard SDG target progress, and ii) evaluate strate-gies of stakeholder-driven adaptation options to meet those needs whilst delivering additional SDG target co -benefits. This methodological process is spatially applied to a national adaptation assessment in Ghana. In the face of the country's risk from floods and landslides, this analysis identifies which energy and transport assets to prioritise in order to make the greatest contribution to safeguarding development progress. Three strategies ('built', 'nature-based', 'combined SDG strategy') were formulated through a multi-stakeholder partnership involving government, the private sector, and academia as a means to protect Ghana's prioritised assets against climate risk. Evaluating these adaptation strategies in terms of their ability to deliver on SDG targets, we find that the combined SDG strategy maximises SDG co-benefits across 116 targets. The proposed methodological process for integrating SDG targets in adaptation assessments is transferable to other climate-vulnerable nations, and can provide decision-makers with spatially-explicit evidence for implementing sustainable adaptation in alignment with the global agendas.

Adaptation action is essential to achieving and safeguarding development outcomes in the face of more frequent and intense climate hazards. This report is the culmination of a 21-month partnership between the Government of Ghana (MESTI), the Global Center for Adaptation (GCA), the University of Oxford, the United Nations Office for Project Services (UNOPS) and the United Nations Environment Programme (UNEP) to identify and propose solutions to address priority adaptation needs in Ghana. Using novel modelling and assessment tools, and through an extensive stakeholder consultation process, it provides an assessment of risk of climate hazard on national infrastructure systems. Next, it develops a roadmap for addressing risks through targeted adaptation options in the built and natural environments, including nature-based solutions. The roadmap also defines institutional interventions required to enhance the enabling environment that ensures the optimum effectiveness of adaptation measures in the country. It is aligned with Ghana’s national development objectives to advance progress towards the Sustainable Development Goals (SDGs), the Paris Agreement on climate change, and gender and inclusivity objectives. The proposed 35 prioritised adaptation options provide opportunities for funders and investors to invest in Ghana’s future, offering impactful, evidence-based adaptation projects and enabling environment interventions backed by robust research and analysis.

Small island developing states face particular challenges to ensure their infrastructure promotes social, economic, and environmental well-being. Closing the achievement gap for the Sustainable Development Goals (SDGs) involves prioritization and coordination across multiple sectors. With an application to the country of Saint Lucia, this paper develops a stakeholder-driven analysis framework integrating four interdependent infrastructure sectors (electricity, water, wastewater, and solid waste). Drawing on extensive consultation with decision-makers in-country—134 stakeholders from 18 government ministries, agencies, academia, or the private sector—the analysis identifies specific interventions that could be implemented over the next decades to meet future needs for sustainable infrastructure services. These interventions are congruent with the government's development plans. Long-term, cross-sectoral portfolios of investments and policies (“strategies”) are developed which demonstrably reach the targets of the SDGs and Saint Lucia's emissions reduction commitments under the Paris Agreement. The sequencing of these investments or policies is designed to optimize their efficiency and impact over time, identifying “quick wins” while ensuring that there is sufficient action to provide services in the long-term sustainably. A comparison of costs associated with each strategy suggests that accounting for interdependencies and taking a long-term perspective can save costs over the life of infrastructure investments. This process of infrastructure assessment is applicable beyond the small island context, allowing practitioners a means to undertake systematic assessment of a country's future infrastructure needs and to develop appropriate solutions aligned with its national objectives and international commitments.

The occupied Palestinian territories of West Bank and Gaza Strip are currently experiencing many challenges in the provision of infrastructure services for their inhabitants. This includes an undersupply of infrastructure services across multiple sectors – an issue exacerbated by population growth, increasing urbanisation, economic growth and climate change. We address this challenge by providing a systems-based assessment of Palestine's infrastructure requirements and identifying broad strategies for how those needs might be met. This assessment involved four key components including: 1) defining and assessing the current system and planned infrastructure investments; 2) assessing potential future demand for infrastructure services; 3) identifying alternative strategies for future infrastructure provision beyond planned investments; and 4) analysing the performance of each strategy against a series of key performance indicators. Results from the assessment highlight the magnitude of the current and future need for urgent infrastructure investment in Palestine. The most immediate need is to alleviate the water crises in Gaza Strip, which will require at least twice as much water infrastructure investment over the coming decade than is currently in the pipeline, even if the goal is only to achieve the most basic World Health Organisation water availability requirements. To move beyond this protracted state of crises will then require a doubling of investments across all sectors to bring Palestine up to the standards of services already enjoyed by its neighbours. Such investments can have even greater impact on delivery of infrastructure services through the strategic use of interdependencies between infrastructure sectors, such as water re-use and energy-from-waste. In the pursuit of global sustainable development, the systems-based approach presented here provides an important first step in the assessment of infrastructure needs and opportunities for any country. It is particularly important for states like Palestine where key resources, such as water and energy, are so acutely constrained.

Through the provision of a range of essential services, infrastructure systems profoundly influence development. At a time of increasing global investment in infrastructure, there is a need to support practitioners in making informed choices in order to achieve progress toward sustainable development objectives. Using the 2030 Agenda for Sustainable Development (the SDGs) as a framework to structure infrastructure decision-making and trade-offs, this analysis develops a performance indicator system that assesses the potential development implications of a portfolio of infrastructure investments and policies. We develop metrics to assess the performance of infrastructure-linked targets. We then embed these metrics in a systems model that allows for the quantification of future infrastructure needs and the assessment of portfolios of infrastructure investments and policies that contribute to meeting these needs. These methods are applied to the small-island country of Curaçao, demonstrating the potential for meeting the SDGs through adoption of strategies of cross-sectoral infrastructure investments and policies in the energy, water, wastewater and solid waste sectors. In the face of growing demands for infrastructure services, we find that inaction with regard to infrastructure supply and demand will lead to a 28% decrease in average SDG achievement across these targets by 2030. We assemble a portfolio of interventions that provide infrastructure services across these four sectors that enable achievement of 19 SDG targets directly linked to infrastructure. These interventions imply scaling up of infrastructure where there are gaps in service provision, ranging from an overall 10% increase in the water sector to a 368% increase in waste sector infrastructure from current capacities by 2030. Achieving the SDGs does not necessarily imply more infrastructure: in the energy sector the sustainable policy implies demand reductions of 32% from current levels. Nearly 50% of the assessed targets require intervention in more than one sector, emphasising the interdependent nature of the infrastructure system. The analysis addresses future uncertainties around the key drivers of residential population and tourism growth on the island by modelling infrastructure needs for alternate scenario projections. Averaged across the four sectors, these needs range from −14% (low) to +5% (high) in relation to the moderate projection. The analysis provides the first step towards a practical means of utilising infrastructure to deliver the SDGs, using quantitative indicators to underpin effective decision-making.
