Uncertainty in capturing the effects of riparian tree shade for assessment of algal growth rates and water temperature hinders the predictive capability of models applied for river basin management. Using photogrammetry-derived tree canopy data, we quantified hourly shade along the River Thames (UK) and used it to estimate the reduction in the amount of direct radiation reaching the water surface. In addition we tested the suitability of freely-available LIDAR data to map ground elevation. Following removal of buildings and objects other than trees from the LIDAR dataset, results revealed considerable differences between photogrammetry- and LIDAR-derived methods in variables including mean canopy height (10.5 m and 4.0 m respectively), percentage occupancy of riparian zones by trees (45% and 16% respectively) and mid-summer fractional penetration of direct radiation (65% and 76% respectively). The generated data on daily direct radiation for 2010 were used as input to a river network water quality model (QUESTOR). Impacts of tree shading were assessed in terms of upper quartile levels, revealing substantial differences in indicators such as biochemical oxygen demand (BOD) (1.58–2.19 mg L-1 respectively) and water temperature (20.1 and 21.2 °C respectively) between ‘shaded’ and ‘non-shaded’ radiation inputs. Whilst the differences in canopy height and extent derived by the two methods are appreciable they only make small differences to water quality in the Thames. However such differences may prove more critical in smaller rivers. We highlight the importance of accurate estimation of shading in water quality modelling and recommend use of high resolution remotely sensed spatial data to characterise riparian canopies. Our paper illustrates how it is now possible to make better reach scale estimates of shade and make aggregations of these for use at river basin scale. This will allow provision of more effective guidance for riparian management programmes than currently possible. This is important to support adaptation to future warming and maintenance of water quality standards

Resilience is a topic of extensive academic discourse as its relevance is elevated in response to climate change. There is limited research into the concept of resilience from the perspective of those in fields of practice. To address this gap, we conducted fieldwork in four cities to ask for perspectives on what enables cities to cope with water related shocks and stresses. Based on analysis of interview responses and focus group discussions, we propose key characteristics of human, societal and institutional capacity necessary for urban water resilience. We discuss findings in the context of evidence gathered in the field and prevalent work in current water resilience literature. It is our hope that this work may provide insights into the critically important human dimensions necessary for a shift towards resilience as a prevailing paradigm for urban water management.

Innovation and understanding hydrological processes are intimately linked. Existing research has demonstrated the role of technological, societal, and political drivers in shaping and delivering new understandings in hydrological processes. In this paper we pose three research questions to explore how innovation can further our understanding of hydrological processes, if working towards the sustainable development goals (SDGs) provides a helpful focus, and whether specific mechanisms can be used to facilitate innovation and research into hydrological processes. First, we examine key aspects of innovation and explore innovation in the context of water security. We then present a series of innovation projects to determine their effectiveness in delivering innovation in managing hydrological processes, but also their contribution to scientific understanding. Our research suggests that product and process innovation were more closely related to increasing scientific understanding of hydrological processes than other forms of innovation. The NE Water Hub demonstrated that the design of the innovation ecosystem was crucial to its success and provides a model to integrate innovation and research more widely to further scientific understanding and deliver behaviour change to address the SDGs.

Society’s greatest use of water is in food production; a fact that puts farmers centre stage in global environmental management. Current management of food value chains, however, is not well set up to enable farmers to undertake their dual role of feeding a growing population and stewarding natural resources. This book considers the interconnected issues of real water in the environment and “virtual water” in food value chains and investigates how society influences both fields. This perspective draws out considerable challenges for food security and for environmental stewardship in the context of ongoing global change. The book also discusses these issues by region and with global overviews of selected commodities. Innovation relevant to the kind of change needed for the current food system to meet future challenges is reviewed in light of the findings of the regional and thematic analysis.

Context: Climate change will alter the global distribution of climatically suitable space for many species, including agricultural crops. In some locations, warmer temperatures may offer opportunities to grow novel, high value crops, but non-climatic factors also inform agricultural decision-making. These non-climatic factors can be difficult to quantify and incorporate into suitability assessments, particularly for uncertain futures.
Objective: To demonstrate how qualitative and quantitative techniques can be combined to assess crop suitability with consideration for climatic and non-climatic factors.
Methods: We carried out a horizon scanning exercise that used Delphi methodology to identify possible novel crops for a region in south-west England. We show how the results of the expert panel assessment could be combined with a crop suitability model that only considered climate to identify the best crops to grow in the region.
Results and conclusions: Whilst improving climate and crop models will enhance the ability to identify environmental constraints to growing novel crops, we propose horizon scanning as a useful tool to understand constraints on crop suitability that are beyond the parameterisation of these models and that may affect agricultural decisions.
Significance: A similar combination of qualitative and quantitative approaches to assessing crop suitability could be used to identify potential novel crops in other regions and to support more holistic assessments of crop suitability in a changing world.

This paper uses game theory to examine the efforts of public sector actors in the UK to integrate climate change interventions within development processes. Drawing on desk-based analysis and interviews, we identify instances where private-sector developers act strategically to exploit public-sector imperatives to deliver economic growth and housing. We find these imperatives constrained the agency of planners to effectively reconcile climate mitigation/adaptation objectives within wider priorities of economic growth. Yet, we identify instances whereby strategic planning frameworks, informal networks and bespoke development frameworks were effective means to build trust between actors and foster co-operation, better enabling development which meets climate change mitigation/adaptation objectives. In doing so, we illustrate the practical and theoretical value of game theory, whilst highlighting how careful use of strategic planning can support achieving climate change mitigation/adaptation objectives at a local scale.

Managing water–human systems during water shortages or droughts is key to avoid the overexploitation of water resources and, in particular, groundwater. Groundwater is a crucial water resource during droughts as it sustains both environmental and anthropogenic water demand. Drought management is often guided by drought policies, to avoid crisis management, and actively introduced management strategies. However, the impact of drought management strategies on hydrological droughts is rarely assessed. In this study, we present a newly developed socio-hydrological model, simulating the relation between water availability and managed water use over 3 decades. Thereby, we aim to assess the impact of drought policies on both baseflow and groundwater droughts. We tested this model in an idealised virtual catchment based on climate data, water resource management practices and drought policies in England. The model includes surface water storage (reservoir), groundwater storage for a range of hydrogeological conditions and optional imported surface water or groundwater. These modelled water sources can all be used to satisfy anthropogenic and environmental water demand. We tested the following four aspects of drought management strategies: (1) increased water supply, (2) restricted water demand, (3) conjunctive water use and (4) maintained environmental flow requirements by restricting groundwater abstractions. These four strategies were evaluated in separate and combined scenarios. Results show mitigated droughts for both baseflow and groundwater droughts in scenarios applying conjunctive use, particularly in systems with small groundwater storage. In systems with large groundwater storage, maintaining environmental flows reduces hydrological droughts most. Scenarios increasing water supply or restricting water demand have an opposing effect on hydrological droughts, although these scenarios are in balance when combined at the same time. Most combined scenarios reduce the severity and occurrence of hydrological droughts, given an incremental dependency on imported water that satisfies up to a third of the total anthropogenic water demand. The necessity for importing water shows the considerable pressure on water resources, and the delicate balance of water–human systems during droughts calls for short-term and long-term sustainability targets within drought policies.

CONTEXT: Farmer-led innovation brings farmers together with other stakeholders in a collaborative endeavour that recognises multiple forms of expertise. Critical engagement with mainstream models of agricultural science and technology (AST) development has drawn attention to the isolation of farmers as technology adopters within a compartmentalised model of AST development and dissemination. Academic, government and non-governmental actors and organisations are increasingly supporting facilitated processes in which farmers, scientists and engineers develop new knowledge, learning together about the nature of the problems being faced and the potential of different solution pathways.
OBJECTIVE: Despite the centrality of learning to farmer-led innovation, its role has yet to be systematically explored. In response, this paper looks to understand the forms of learning and their contribution to farmer-led innovation during a three-year action-research project involving two groups of farmers from northern England and the Scottish Borders in the UK.
METHODS: A researcher-facilitator convened a structured process of twenty meetings that together created opportunities for interaction, deliberation and re-framing of problems and solutions among groups of farmers, a university-based engineer, and wider stakeholders. Multiple qualitative methods were used to build understanding of the different farming contexts and to explore the issues the farmers wanted to work on. Meeting transcripts and fieldnotes were subject to thematic analysis, informed by the analytical framework of cognitive, normative and relational learning derived from the social learning literature.
RESULTS AND CONCLUSIONS: Cognitive, normative and relational learning were found to be mutually interdependent and equally significant, building iteratively rather than linearly: the farmers and engineer assessed new information and reappraised existing situations; they did so informed by and informing a shift in understanding of their goals for new technology; and in so doing they relied on and developed the trust and confidence needed to acknowledge or challenge each other's perspectives. By orientating the group engagement process around the space to explore and challenge histories and contexts of AST, and by drawing on social learning principles to facilitate interaction between the different expertise of farmers and between farmers and engineers, learning emerged that interleaved technology co-design with incremental refinement of the shared norms and values embedded in the process itself.
SIGNIFICANCE: A focus on learning helps deepen understanding of key mechanisms and processes that define and deliver innovation, and the findings suggest that priorities for farmer-led innovation process design should focus on modalities that open up spaces to negotiate both the purpose and products of innovation.

A wide range of nature-based solutions for flood hazard management work by storing and slowing flow within catchments, and therefore, there is a need to identify the optimal locations for implementing these solutions. This paper presents a relative scoring-based mapping of the likely locations that contribute to the flood peak. Targeting flow reduction and attenuating mitigation actions in these locations can be an effective way to reduce flood damages at impact points downstream. The presented tool, SCIMAP-Flood, uses information on land cover, hydrological connectivity, flood generating rainfall patterns and hydrological travel time distributions to impacted communities to find the potential source areas of flood waters. The importance of each location in the catchment is weighted based on its contribution to the flood hazard at each of the downstream impact points. In the example application, SCIMAP-Flood is applied at a 5-m grid resolution for the River Eden catchment, Cumbria, England, to provide sub-field scale information at the landscape extent. Therefore, the tool can identify sub-catchments where more detailed work can test different mitigation measures.
