Building on the existing literature, this study examines whether specific drivers of forest fragmentation cause particular fragmentation characteristics, and how these characteristics can be linked to their effects on forest-dwelling species. This research uses Landsat remote imaging to examine the changing patterns of forests. It focuses on areas which have undergone a high level of a specific fragmentation driver, in particular either agricultural expansion or commodity-driven deforestation. Seven municipalities in the states of Rondônia and Mato Grosso in Brazil are selected as case study areas, as these states experienced a high level of commodity-driven deforestation and agricultural expansion respectively. Land cover maps of each municipality are created using the Geographical Information System software ArcGIS Spatial Analyst extension. The resulting categorical maps are input into Fragstats fragmentation software to calculate quantifiable fragmentation metrics for each municipality. To determine the effects that these characteristics are likely to cause, this study uses a literature review to determine how species traits affect their responses to forest fragmentation. Results indicate that, in areas that underwent agricultural expansion, the remaining forest patches became more complex in shape with longer edges and lost a large amount of core area. This negatively affects species which are either highly dispersive or specialist to core forest habitat. In areas that underwent commodity-driven deforestation, it was more likely that forest patches would become less aggregated and create disjunct core areas. This negatively affects smaller, sedentary animals which do not naturally travel long distances. This study is significant in that it links individual fragmentation drivers to their landscape characteristics, and in turn uses these to predict effects on species with particular traits. This information will prove useful for forest managers, particularly in the case study municipalities examined in this study, in deciding which species require further protection measures. The methodology could be applied to other drivers of forest fragmentation such as forest fires.

Global responses to COVID-19 will impact on delivery of the 17 Sustainable Development Goals by 2030, creating large uncertainties just at the time efforts need to be accelerated. This paper explores how COVID-19 could impact the success of meeting the targets with priority given to the four ‘foundational’ goals: SDG 1 No Poverty; SDG3 Good Health; SDG 14 Life Below Water and SDG 15 Life on Land as these are critical in maintaining a healthy human and environmental resource base on which progress towards all goals can be built. A scenario analysis examines futures across a spectrum in which i) social and health imperatives (lives) dominate, to ii) where economic imperatives (livelihoods) take precedence. Similarly levels of international co-operation are considered ranging from international recognition of urgent global agendas to fragmentation due to the isolation of individual states around national priorities. These give rise to 4 scenarios: a) Global Well-being Prioritized b) World Trade Recovers c) Poverty Gaps Widen c) Earth Systems in Danger and the likelihood of achieving the foundational SDGs in each is discussed. The paper concludes opportunities exist to refocus efforts on delivery of the SDGs but may be hampered by the competing interests of a new geopolitics.

This study examines whether catchment‐scale natural flood management (NFM) interventions could help to manage water levels in downstream urban watercourses and promote free discharge from surface drainage outfalls. A coupled modelling approach consisting of Dynamic TOPMODEL, HEC‐RAS, and Infoworks ICM models is used to characterise the response from a small Cambridgeshire catchment. Four different NFM scenarios (consisting of in‐channel woody debris and wider catchment afforestation) are defined. The attenuation of catchment response created by these measures is evaluated for an historic event and six different design storms. The consequent moderation of water depths at two downstream drainage outfalls is investigated with respect to maintaining free discharge from a surface drainage system. The case study results show that greatest reductions in the time of outfall inundation from NFM occur during frequent storm events (e.g., up to 5.75 hr during a 5‐year event). These reductions diminish with increasing storm severity but, by slightly desynchronising rural and urban responses, upstream interventions continue to have modest benefit for downstream drainage performance (e.g., preventing system capacity being exceeded during a 100‐year event). These results may interest water companies (increasingly involved in catchment‐scale NFM projects) looking to improve performance of surface water drainage.

This paper reviews the civil engineering profession’s progress towards sustainability over the past decade in eight key areas. It finds there have been significant steps forward in assessment methods, systems thinking, multi-functional infrastructure, flexible and adaptive design, and adoption of a circular economy in construction. However, it also finds the sustainability challenge is accelerating and much more needs to be done to go beyond business as usual. In particular civil engineers need to be more vocal in calling out projects and practices that go counter to the planet’s and society’s needs.

A range of solutions to future flood risk are available ranging from blue-green infrastructure (BGI) as commonly incorporated in sustainable drainage systems (SuDS) to traditional grey infrastructure (e.g. pipe networks, storage tanks, flood walls). Each offers a different profile with respect to costs, flexibility of implementation and the ability to deliver a range of wider benefits beyond their flood protection function. An important question that must be addressed when considering these approaches is what is the most suitable mix of grey and blue-green solutions to urban flooding at any location and at any future time? This paper uses an adaptation pathways approach to compare a range of alternative options to deal with current and expected future flood risk in part of a London borough. Solutions considered separately and in combination include grey pipe expansion, bioretention cells, permeable pavements and storage ponds. A methodological framework combines a range of existing tools to develop, assess and characterize each pathway, including a storm water management model (SWMM), a SuDs opportunity selection tool, an adaptation pathway generator and the CIRIA B£ST tool for monetizing multiple benefits. Climate change is represented by the UK Water Industry Research method for establishing future rainfall intensities for sewer and BGI design. The results showed that by extending the way in which adaptation pathways are compared and evaluated through the wider consideration of multiple benefits there is a trade-off between deferring interventions until they are needed for flood risk mitigation and delivering the multiple benefits associated with interventions so that performance thresholds do not need to be met before introducing new options. The relative contribution of each option's capital and operation and maintenance costs has implications on when the option is implemented as well as the rate of implementation. The monetization of the multiple benefits associated with each pathway shows that their economic co-evaluation alongside infrastructure costs can change the preference for one pathway over another. This article is part of the theme issue ‘Urban flood resilience’.

A limited number of previous studies have explored the viability of energy recovery and the possible systems and configurations by which this can be achieved from stormwater retention ponds and suggest the potential for this is worth pursuing. This paper develops a novel screening tool for the evaluation of the energy recovery potential at a given site with the clear purpose of providing a new specific methodology to conduct a preliminary analysis to determine whether it is worth going further in terms of subsequent design and implementation. The application of the tool to two case studies highlights a number of critical dependant factors suggesting energy recovery from stormwater is likely to be limited to locations that have abundant rainfall relatively evenly distributed around the year, a large contributing catchment and steep slopes. Scheme viability is judged by the revenue capable of being generated by the installation over a 20 year payback period and in both cases examined the investment recovery was found to be low (3% and 14% respectively). An envelope of where energy recovery might be feasible to provide a typical annual electrical output consistent with other viable micro-hydropower schemes is presented. The procedures proposed can be of practical use to asset owners and local authorities where retention ponds are already being planned.

Achieving urban flood resilience at local, regional and national levels requires a transformative change in planning, design and implementation of urban water systems. Flood risk, wastewater and stormwater management should be re-envisaged and transformed to: ensure satisfactory service delivery under flood, normal and drought conditions, and enhance and extend the useful lives of ageing grey assets by supplementing them with multi-functional Blue-Green infrastructure. The aim of the multidisciplinary Urban Flood Resilience (UFR) research project, which launched in 2016 and comprises academics from nine UK institutions, is to investigate how transformative change may be possible through a whole systems approach. UFR research outputs to date are summarised under three themes. Theme 1 investigates how Blue-Green and Grey (BG + G) systems can be co-optimised to offer maximum flood risk reduction, continuous service delivery and multiple co-benefits. Theme 2 investigates the resource capacity of urban stormwater and evaluates the potential for interoperability. Theme 3 focuses on the interfaces between planners, developers, engineers and beneficiary communities and investigates citizens’ interactions with BG + G infrastructure. Focussing on retrofit and new build case studies, UFR research demonstrates how urban flood resilience may be achieved through changes in planning practice and policy to enable widespread uptake of BG + G infrastructure.

Until recently the extensive inter-dependencies between the 17 Sustainable Development Goals, which consist of 169 targets, has received limited attention. Furthermore, the impact of the non-achievement of the Sustainable Development Goals may expose humanity to forms of global catastrophic risk and existential risk. The paper examines systems approaches to identify and prioritise key SDGs whose implementation will have a desired feedback effect on other goals. Leverage points are also identified which may mitigate potential causes of global catastrophic risk and existential risk if the SDGs are not achieved, or if reinforcing feedback loops dominate. An awareness of these loops is essential and understanding the nature of the system structure they embody is important for the design of effective policy interventions. Through a detailed inspection of a Causal Loop Diagram which conceptually links all the goals based on a review of recent literature, the following foundational Sustainable Development Goals are identified; SDG 1 No Poverty; SDG3 Good Health and Well Being; SDG 14 Life Below Water and SDG 15 Life on Land. These represent vital outcomes of achieving other goals and they are also critical in maintaining both a healthy human and environmental resource base on which progress towards all goals can be built. By examining a range of potential global threats based on a review of global catastrophic risk and existential risk, a further set of goals that can act as important leverage points are identified. The most important of these is SDG 13 Climate Action and SDG 4 Quality Education with SDG 2 Zero Hunger, SDG 8 Decent Work and Economic Growth, SDG12 Responsible Consumption and Production and SDG 16 Peace Justice and Strong Institutions also having important roles to play. The interaction of all SDGs, acting synergistically together, is important to move the global system towards desirable outcomes and reduce currently increasing levels of risk.

Bangladesh is one of the countries most vulnerable to climate change, while its people also suffer from a range of environmental hazards linked to the growing prevalence of non-communicable diseases. These diseases are responsible for increasing morbidity and mortality and lead to other stresses within the population. Such stresses create continuous impacts on the health and well-being of the population, compounding their vulnerability and inhibiting their capacity to cope with frequent event-related shocks, such as floods and drought. A systems approach is taken to examine four important environmental hazards in Bangladesh—arsenic contamination of drinking water, arsenic transmission through the food chain, indoor air quality, and air pollution. A review of these hazards is presented in a conceptual framework that links human well-being with the key system components of infrastructure, institutions, knowledge, and behavior. This reveals key underlying factors between the hazards and uncovers system structures that can lead to more effective hazard mitigation, and the establishment of strategic intervention points. The article concludes that elimination of these continuous stresses will only come about through the culmination of multiple interventions over time, undertaken in an iterative manner that builds on the continual advancement of hazard understanding. The role of individual behaviors, together with factors such as risk awareness and perception of the hazards, has been identified as crucial for achieving successful mitigation solutions. Improved knowledge of the hazards, public awareness, and government accountability are focus points to reduce population exposure and enhance response capacity.

Preliminary results of the UK Urban Flood Resilience research consortium are presented and discussed, with the work being conducted against a background of future uncertainties with respect to changing climate and increasing urbanization. Adopting a whole systems approach, key themes include developing adaptive approaches for flexible engineering design of coupled grey and blue-green flood management assets; exploiting the resource potential of urban stormwater through rainwater harvesting, urban metabolism modelling and interoperability; and investigating the interactions between planners, developers, engineers and communities at multiple scales in managing flood risk. The work is producing new modelling tools and an extensive evidence base to support the case for multifunctional infrastructure that delivers multiple, environmental, societal and economic benefits, while enhancing urban flood resilience by bringing stormwater management and green infrastructure together.

Access to continuous water supply is key for improving health and economic outcomes in rural areas of low- and middle-income countries, but the factors associated with continuous water access in these areas have not been well-characterized. We surveyed 4786 households for evidence of technical, financial, institutional, social, and environmental predictors of rural water service continuity (WSC), defined as the percentage of the year that water is available from a source. Multiple imputed fractional logistic regression models that account for the survey design were used to assess operational risks to WSC for piped supply, tube wells, boreholes, springs, dug wells, and surface water for the rural populations of Bangladesh, Pakistan, Ethiopia, and Mozambique. Multivariable regressions indicate that households using multiple water sources were associated with lower WSC in Bangladesh, Pakistan, and Mozambique. However, the possibility must be considered that households may use more than one water source because services are intermittent. Water scarcity and drought were largely unassociated with WSC, suggesting that service interruptions may not be primarily due to physical water resource constraints. Consistent findings across countries may have broader relevance for meeting established targets for service availability as well as human health.

Urban drainage systems that incorporate elements of green infrastructure (SuDS/GI) are central features in Blue-Green and Sponge Cities. Such approaches provide effective control of stormwater management whilst generating a range of other benefits. However these benefits often occur coincidentally and are not developed or maximised in the original design. Of all the benefits that may accrue, the relevant dominant benefits relating to specific locations and socio-environmental circumstances need to be established, so that flood management functions can be co-designed with these wider benefits to ensure both are achieved during system operation. The paper reviews a number of tools which can evaluate the multiple benefits of SuDS/GI interventions in a variety of ways and introduces new concepts of benefit intensity and benefit profile. Examples of how these concepts can be applied is provided in a case study of proposed SuDS/GI assets in the central area of Newcastle; UK. Ways in which SuDS/GI features can be actively extended to develop desired relevant dominant benefits are discussed; e.g., by (i) careful consideration of tree and vegetation planting to trap air pollution; (ii) extending linear SuDS systems such as swales to enhance urban connectivity of green space; and (iii) managing green roofs for the effective attenuation of noise or carbon sequestration. The paper concludes that more pro-active development of multiple benefits is possible through careful co-design to achieve the full extent of urban enhancement SuDS/GI schemes can offer.

Clay balls can be used as an alternative to natural pebbles in pebble matrix filtration, a method for drinking water treatment. These clay balls are subjected to stresses due to self-weight and overburden in water-saturated conditions. Although there are empirical relationships to evaluate tensile yield strength (Ts) of clay balls using Poisson’s ratio (μ), diameter (d) of clay balls, and failure polar force (Fs), so far for such calculations the value of Poisson’s ratio has been taken from studies based on clay bricks. However, during ball preparation, if clay is mixed with other raw materials from industry wastes, such as saw dust or alum sludge in order to enhance the pollutant removal properties of the filter media, then the Poisson’s ratio of composite balls would be quite different from that of clay bricks. This paper describes a novel method for estimating Poisson’s ratio of composite clay balls by measuring vertical deformation using LVDTs in a uniaxial compressive strength (UCS) apparatus and lateral deformation using particle image velocimetry (PIV).

Urban water managers must provide adequate water supplies to meet growing demands for a range of water uses (including essential drinking water) whilst mitigating the negative effects of water in the wrong place, which occur at times of flood arising from extreme weather events. Many urban areas around the world are becoming increasingly water stressed, and cities such as London are developing solutions to address expected future shortages. As well as physical challenges, this chapter discusses problems of effective water governance and how decision-making across multiple scales is needed for effective water resource management—combining both technical and non-technical innovations. Current practice is characterised by many unsustainable activities, with many cities locked into a legacy of ageing infrastructure systems developed in the past. Key characteristics of more sustainable water systems are presented which represent the paradigm shift that is required in how urban water is dealt with. Features of urban water resilience are examined which can be achieved through an iterative adaptive management approach to water management. Examples are given that relate to the use of green infrastructure to achieve water-sensitive urban design, which mitigates the adverse effects of storm water at locations where the rain falls, whilst simultaneously providing a range of other benefits. Multifunctional infrastructure is described where innovative engineering can deliver more than one service from a single purpose project. The chapter concludes by stressing the need to see the urban water system as part of the wider urban fabric which positively adds to the layout, security and liveability of future cities.

The UK government has proposed different low-carbon energy system options that lead to meeting its greenhouse gas emissions target of 80% reduction on 1990 levels by 2050. While these energy system options meet emission targets at feasible economic cost, water requirement for the deployment of the proposed energy technology mix is not adequately accounted for. This may become critical, as some of the proposed energy technologies are relatively more water-intensive, and could result in significant future water resource constraints. Previous studies have analyzed the potential water resource constraints of future energy systems in the UK at national scale. However, water must be considered as a local resource with significant regional variability. This paper uses a linear spatial-downscaling model to allocate water-intensive energy system infrastructure/technologies at catchment level, and estimates water requirements for the deployment of these technologies for the Committee on Climate Change Carbon Budgets in 2030. The paper concludes that while national-scale analysis shows minimal long-term water related impacts, catchment level appraisal of water resource requirements reveals significant constraints in some locations. This has important implications for regions where the water-energy nexus must be analyzed at appropriate spatial resolution to capture the full water resource impact of national energy policy.

This paper focuses on the spatial distribution of the dominant and relevant benefits of urban flood management based on context- and location-specific evaluations. We explore the conceptual rationale and describe a detailed methodology for assessing the benefit profile, benefit intensity, and comment on benefit dependencies arising from urban flood management practices that utilise green infrastructure. A case study is described which demonstrates the application of the concepts in Portland, Oregon, USA. A Geographic Information System approach is developed to evaluate some of the multiple benefits of the East Lents Floodplain Restoration Project. Results are presented in the form of a comparative benefit profile, and a spatially distributed benefit intensity. The paper concludes with the implications of the methodology for future multiple benefit evaluation of urban drainage and flood management systems.
