This paper evaluates the potential for reconfiguring city-scale clean water demand by reducing the non-residential asset sanitsation water footprint. A novel methodological framework is proposed for assessing the feasibility of a mix of three surface sanitisation measures (Manual surface wiping, Mechanical cleaning/Rapid disinfectant spraying, Ultraviolet germicidal irradiation-UVGI treatment) in terms of a Sanitisation waterfootprint index (SWI); three typical application scenarios are considered – high risk-high frequency, moderate risk-moderate frequency, moderate risk-low frequency. The UVGI treatment outperforms the other two surface treatment methods, particularly in high risk-high frequency scenario in the healthcare setting, with SWI as low as 2%. Further, case-study evidence from a ward-level spatial analysis using real-world data estimates SWI ranging between 0-30% in those wards with greater commercial/public assets, showing clear merit of this framework in re-configuring city-scale public health sanitisation water footprint. A cost-benefit analysis (involving resources – staffing, water and chemicals; capital expenditure, and energy costs) shows superior performance of UVGI treatment over the other two methods from the second year onwards, surpassing the initial cost-effectiveness for corresponding manual or mechanical cleaning. Wider implementation of this framework can foster strategic transformation of city-scale water footprint, which is deemed essential for ensuring sustainable growth of water deficient cities globally.

Cities are increasingly adopting potentially sustainable climate plans. Integrating the Sustainable Development Goals (SDGs) into these plans could help stabilize the climate while generating jobs, narrowing equity gaps, fostering innovation, and delivering other sustainability benefits. Yet, how much cities are integrating the SDGs into climate plans remains poorly understood. This article shed light on this question with a text analysis of SDG “keywords” in climate plans for two British and two Japanese cities. The results revealed that none of the surveyed cities have connected climate with socioeconomic priorities covered in SDG1 (poverty), SDG8 (employment), SDG5 (gender), and SDG10 (inequalities). Meanwhile, the United Kingdom cities made more connections between climate and responsible consumption and production (SDG12) than the Japanese cities. Further, Kyoto, Japan shares a climate-SDGs linkages profile that resembles the United Kingdom cities more than Kawasaki. Though not without limitations, text analysis can facilitate the city-to-city peer learning needed to make urban climate plans sustainable within and across countries.

This paper critically examines the literature on the grid-offgrid debate and discusses the role of and the relationship between different electricity access options through a synthesis and critical reflection. This paper finds that models using greater resolution and capturing low voltage distribution infrastructure appear to recommend decentralised electricity solutions, whereas central grid extension emerges as the preferred outcome of more aggregated analysis, concentrated population clusters and for higher demand scenarios. However, model results are seriously influenced by assumptions, data limitations, technology choice options, and model flexibility. Exclusion of cost of generation for grid systems, lack of village level information, inherent bias towards scale and type of technology, and absence of social equity considerations in the analysis remain major weaknesses of the existing models. Universal electrification requires a strong leadership and an enabling environment. An appropriate organizational set-up, a robust regulatory framework with reporting and evaluation oversight and a more inclusive approach to promote alternative options are vital ingredients. Power sector decarbonization pathways may affect electrification choices but our understanding is limited or lacking. Further work is required to develop a programmatic approach to delivery and more affordable and fairer outcome for all.

The Niger Delta is under severe threat from the impacts of climate change in the form of flood, rising temperature, surging Atlantic tides, persistent heavy rainfall, and windstorms. The severity of the impacts on current and planned oil/gas infrastructures calls for urgent adaptation strategies. To adapt effectively, prioritization of oil and gas infrastructures according to their criticality is crucial. This article applied a systematic review of highly referenced journal articles published between 2008 and 2019 to scope and synthesize specific criticality assessment criteria for evaluation. Analytic hierarchy process (AHP) was implemented in criteria-based pairwise comparison and prioritization of selected infrastructures. Practitioners with at least ten years of experience in the oil/gas industry in the Niger Delta were stratified accordingly for data collection through a perception-based pairwise comparison technique. The result was analyzed using Mi-AHP software and shows the global priorities (eigenvector, EV) for each asset. Terminals, flow stations, and roads/bridges obtained the highest EV = 0.27, 0.19, and 0.15, respectively, indicating their high criticality level in the oil and gas assets value chain. The result also shows that transformers/high voltage cable are the fourth most critical systems obtaining EV = 0.14 while pipelines, loading bays, and wellheads were ranked fifth, sixth, and seventh with EV = 0.11, 0.09 and 0.05. The article portrays AHP as an effective tool in decomposing complex decision-making processes for evaluation of critical infrastructures for climate adaptation planning in the oil and gas industry.

This chapter introduces the economic concepts related to pricing of energy in different market conditions. The chapter starts with the basic competitive market model and discusses the extensions required to analyse specific features (such as indivisibility of capital, specificity of assets, capital intensiveness, etc.) of the energy sector. The chapter also covers the issue of market failure and presents the commonly used market interventions in such situations. The concept of cost-benefit analysis is used as the framework for most of the analysis. The principles of energy pricing are then introduced and the economic rationale behind energy taxation is considered.

The purpose of this chapter is to consider energy demand at the sector level. Major energy using sectors such as industry, transport, and households have their specific features that an aggregated analysis cannot capture. A sector level analysis provides a better understanding of the demand by identifying relevant drivers. This chapter first presents the disaggregation of energy demand, discusses the information issues and introduces frameworks/tools for a disaggregated analysis.

This chapter focuses on the economic issues related to energy security concerns. Security of supply issues have traditionally focused on oil price volatility and the disruption of supply due to fossil fuel depletion. The attention then shifted to threats to infrastructure and the possibilities of disruption due to inadequate investments in infrastructure or market manipulation by market players. The outlook for energy security has changed significantly post-economic crisis of 2008 due to oversupply situation and the rapid penetration of renewable energies. The contemporary thinking on energy security has moved away from the traditional focus and accordingly, this chapter explains the concept, introduces the economic dimension of the problem and discusses the policies that can mitigate the issue.
