Grainger S, Hommes L, Karpouzoglou T, et al., 2019, The development and intersection of highland-coastal scale frames: a case study of water governance in central Peru, Journal of Environmental Policy and Planning, ISSN: 1523-908X
© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. Scale framing makes an important difference to how complex environmental policy issues are defined and understood by different groups of actors. Increasing urban water demand and uncertain future climatic conditions in the Andes present major water governance challenges for the coastal regions of Peru. An understudied dimension of Peruvian water governance is how scale framing shapes the way problems are defined, and solutions are pursued. Here, we aim to strengthen the understanding of scale framing as it relates to highland-coastal interactions in central Peru between 2004 and 2015. By analysing this period of significant water governance reforms, we identify five prominent water-related frame dimensions and three differently scaled policy storylines and reveal how they developed and intersected over time. The storylines, supported by particular visualisations, either foreground ‘urbanshed’-level investment in water supply infrastructure, community-level cultural restoration for improved local agricultural production, or nationwide watershed-level financial mechanisms for highland ecosystem conservation. Our study shows how the intersection of these storylines at different moments during the policy process often had a strengthening effect, creating a coalition of actors who were then able to generate sufficient momentum and support within the Peruvian government for the implementation of conservation-based watershed investments.
Agrawal S, Chakraborty A, Karmakar N, et al., 2019, Effects of winter and summer-time irrigation over Gangetic Plain on the mean and intra-seasonal variability of Indian summer monsoon, Climate Dynamics, ISSN: 0930-7575
© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. The decreasing trend in rainfall in the last few decades over the Indo-Gangetic Plains of northern India as observed in ground-based observations puts increasing stress on groundwater because irrigation uses up to 70% of freshwater resources. In this work, we have analyzed the effects of extensive irrigation over the Gangetic Plains on the seasonal mean and intra-seasonal variability of the Indian summer monsoon, using a general circulation model and a very high-resolution soil moisture dataset created using extensive field observations in a state-of-the-art hydrological model. We find that the winter-time (November–March) irrigation has a positive feedback on the Indian summer monsoon through large scale circulation changes. These changes are analogous to a positive North Atlantic Oscillation (NAO) phase during winter months. The effects of the positive NAO phase persist from winter to spring through widespread changes in surface conditions over western and central Asia, which makes the pre-monsoon conditions suitable for a subsequent good monsoon over India. Winter-time irrigation also resulted in a reduction of low frequency intra-seasonal variability over the Indian region during the monsoon season. However, when irrigation is practiced throughout the year, a decrease in June–September precipitation over the Gangetic Plains, significant at 95% level, is noted as compared to the no-irrigation scenario. This decrease is attributed to the increase in local soil moisture due to irrigation, which results in a southward shift of the moisture convergence zone during the active phase of monsoon, decreasing its mean and intraseasonal variability. Interestingly, these changes show a remarkable similarity to the long-term trend in observed rainfall spatial pattern and low-frequency variability. Our results suggest that with a decline in the mean summer precipitation and stressed groundwater res

© 2018 The hydrological evidence on which water resource management and broader governance decisions are based is often very limited. This issue is especially pronounced in lower- and middle-income countries, where not only data are scarce but where pressure on water resources is often already very high and increasing. Historically, several governance theories have been put forward to examine water resource management. One of the more influential is Elinor Ostrom's theory of common-pool resources. However while used very widely, the underlying principles of Ostrom's approach make pronounced implicit assumptions about the role of data and evidence in common-pool resource systems. We argue here this overlooks how power relations, user characteristics, system arrangements, and technological advances modulate fundamental associations between data, evidence, and governance, which we contend need to be considered explicitly. Examining the case of water allocations in Quito, Ecuador, we develop a set of concrete criteria to inform the ways in which Ostrom's principles can be applied in a data-scarce, institutionally complex, polycentric context. By highlighting the variable impact of data availability on subsequent evidence generation, these criteria have the potential to test the applicability of common assumptions about how to achieve water security in a developmental context, and hence offer the possibility of developing a more encompassing theory about the interactions between water data, evidence, and governance.

Policy makers are increasingly aware that decision-making in the context of ecosystem services management, and of development, can benefit from collaborative and inclusive approaches to knowledge generation and the design of intervention strategies, such as by providing a more prominent role for indigenous knowledge in decision-making and by using participatory methods for data collection and knowledge generation. In this chapter, we discuss how technologies such as mobile phones, low-cost and robust sensors, and increasingly pervasive remote-sensing satellites and drones can be particularly transformative in the way they facilitate the creation, access and transmission of information about ecosystem services, and support evidence-based decision-making. Furthermore, we discuss how these technologies can be used to promote stakeholder involvement in the knowledge generation process and to make it more inclusive and participatory. While we highlight potential risks related to the use of new technologies, such as exploitation by specific stakeholders to support specific agendas or interests, we identify opportunities for an increasing diversification and tailoring of knowledge creation, moving away from a top-down process dominated by scientists and toward more decentralised, bottom-up and iterative approaches that can have a transformative impact on local ecosystem services management, making it more inclusive, polycentric, evidence-based and robust.

© 2018 selection and editorial matter, Kate Schreckenberg, Georgina Mace and Mahesh Poudyal; individual chapters, the contributors. Ecosystem service frameworks connect with different societal goals and priorities regarding ecosystem management and development planning, and thus reflect the different epistemic communities from which they arise. Since the publication of the Millennium Ecosystem Assessment (MA), ecosystem service framing has undergone a significant evolution and this evolution has, in turn, continued to reshape the epistemic communities and their take on policy instruments, including for example payments for ecosystem services. This chapter explores the development of ecosystem services framings over the last decade, focusing on how the ecosystem service frameworks, such as the UN-led Economics of Ecosystems and Biodiversity (TEEB), the UK-led Ecosystem Services for Poverty Alleviation (ESPA) programme and the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), have significantly influenced how we conceptualise and use the ecosystem service approach. Through an exploration of the evolution of ecosystem service and well-being framings, the chapter highlights that there has been a substantial shift towards seeing ecosystem services through a richer lens, departing from a mostly supply (biophysical) perspective to a more balanced social-ecological perspective, including the issues of equity and justice in ecosystem governance, and a pluralistic conceptualisation of values.

This chapter documents the motivations and methods of the Regional Initiative for Hydrological Monitoring of Andean Ecosystems (iMHEA). First, it introduces the context that led to the formation of a diverse consortium of institutions with a joint interest in Andean ecosystems and water. The methodological approach adopted by the monitoring network is then presented in detail. Lastly, this chapter shows preliminary main results, the most relevant milestones and breakthroughs, and the major remaining challenges and perspectives in the scientific, technological and social domains. The objective of the monitoring, as promoted by iMHEA, is to generate standardized data that can be used to increase the knowledge about hydrological ecosystem services in Andean watersheds and the impacts of watershed interventions. The correct use of the generated knowledge, from community level to national governance entities, proves crucial to increase catchment intervention efficiency and improve decision-making on water resources management in data-scarce regions, with potential application to other regions of the world.

Pandeya B, Buytaert W, 2017, Citizen science and web-based modelling tools for managing freshwater
The use of low-cost hydrological sensors in Nepal allowed local stakeholders to generate useful data on freshwater resources in partnership with scientists, and to apply this data more effectively in participatory decision making.It is important to use the right mapping and modelling methods for ecosystem services (the benefits people obtain from ecosystems) so that information on service production, distribution and consumption is expressed at a spatial scale that is relevant to decision making. These methods are even more important in regions where limited data is available.The integration of appropriate citizen science practices as well as mapping and modelling tools into water and land resources based decision making could facilitate sustainable development activities, particularly in the Himalayan region.
