Bridging the floods − The role of social learning for resilience building in urban water services

The development of cities is increasingly threatened by a worldwide water crisis. Urban water services (including drinking water, sanitation and drainage) are facing complex and multiple pressures, which are becoming increasingly frequent and severe. These pressures include floods, and the depletion, pollution and degradation of water resources and their associated ecosystems. These diverse pressures fall mainly within the domains of flood risk and water resources management: two working fields that are divided by different institutional structures, approaches and practices. Social learning is becoming increasingly popular as an approach that has the potential to “bridge” these silos, and ultimately, contribute to building resilience in urban water services. However, empirical analyses on this issue are rare and fragmented. In her PhD thesis, Åse Johannessen fills this gap. Her results identify challenges to the integration of the identified silos, what resilience means for urban water services, and the key elements of social learning that can support or inhibit urban water resilience.

 
Soluciones Basadas en la Naturaleza para la gestión del agua en España

A new report about nature-based water management solutions in Spain shows that natural infrastructure can a cost-effective the basis for water security. It consolidates recommendations and provides a sound basis for moving forward with scaling up nature-based solutions for water security in Spain. Ensuring water security is a complex, although not intractable challenge, that is too large for any single institution to take on: it calls for collective action with the participation of public and private sector, as well as local, national, multilateral and civil society organizations and individuals.

 
Towards a legal and institutional framework for cooperation at the Nile – new book out now!

Cooperation in the use and management of the Nile will become indispensable in view of the demographic challenges yet to come. Prerequisite for a close cooperation is a legal and institutional framework. However, the Nile basin countries have not yet been able to agree on a permanent form for joint water management. A new book by Dr Philine Wehling provides a comprehensive legal assessment of the existing treaty law governing the use and management of the Nile. It analyses the 2010 Nile River Basin Cooperative Framework Agreement and recommends important amendments to its content. Furthermore, the book operationalizes the principle of equitable and reasonable utilisation and applies it to the Nile. Combining the legal assessment with the operationalization of international law principles, it offers a valuable resource for academics and practitioners seeking to design a permanent legal and institutional framework for cooperation in the Nile basin.

 
Decision Making under Deep Uncertainty

This book focuses on both the theory and practice associated with the tools and approaches for decision-making in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process.

 
Freshwater Governance for the 21st Century – free book

Freshwater Governance for the 21st Century contains information that many practitioners in the water field will be looking for. The water-related challenges have reached a climax with an unoptimistic future expected to feature more competition between users. These stresses will be exacerbated by climate change which is likely to increase water demand while shrinking water supplies. Intense competition for water resources will be experienced not only by private users but will also affect the public sector; however, national plans repeatedly fail to show the ability to provide a coherent outlook for development in which water needs are adequately projected and resources smartly shared. 

 
Delivering on sustainable infrastructure for better development and better climate

As an essential foundation for achieving inclusive growth, sustainable infrastructure underpins all economic activity. Inadequate infrastructure remains one of the most pervasive impediments to growth and sustainable development, and consequently in tackling poverty. Good infrastructure unshackles and removes constraints on economic growth and helps increase output and productivity. Investment in sustainable infrastructure can help generate employment, boost international trade, industrial growth, and competitiveness while reducing inequalities within and among countries.

 
Groundwater as a Buffer to Climatic Change: Dynamic Subsurface Storage of Glaciated Landscapes

29 June 2018 • The northeastern United States is experiencing rapid changes in its hydrology due to intense land-use change, urbanization, and climate change. It also possesses some of the highest density, longest term observations of hydrologic variables (streamflow, groundwater levels) in the US and the world. The focus of this presentation is how small unconfined aquifer systems, and the streams to which they are connected, respond to hydroclimatic and land use changes. 2018 Birdsall-Dreiss Lecture: Groundwater as a Buffer to Climatic Change: Dynamic Subsurface Storage of Glaciated Landscapes

 
Effects of multi-layering in a classical pumping test

To demonstrate several techniques for the analysis of pumping tests in confined aquifers Vedat Batu (1998) presents Example 4-6 on page 160–161 of his book «Aquifer Hydraulics». The pumping well (Q = 540 m3/d) and the two observation wells (r = 25 m and r = 75 m) are fully penetrating. Resulting transmissivities and storativities of the various methods are found between T = 174 and 260 m2/d, and between S = 0.000135 and S = 0.000666. All methods show a rather poor fit, mainly because the measured drawdown rate during the first 30 minutes is clearly higher than in the later period of the test. A much better fit can be obtained when the data of both observation wells are analyzed with the MLU software and a two-aquifer (analytical) model is used.

 
Життя без сміття і з чистою водою. Чим дивує приїжджих Чехія

Питна вода з-під крана, всі на велосипедах і відсутність поняття «сміття». Про те, що для українця – дивина, а для жителя невеличкого чеського міста – буденність, розповіла кореспонденту «СК» харківська науковиця Юлія Виставна.

 
Flow regime alteration due to anthropogenic and climatic changes in the Kangsabati River, India

According to the ‘natural flow paradigm’, any departure from the natural flow condition will alter the river ecosystem. Flow regimes have been modified by anthropogenic interventions and climate change is expected to cause additional impacts by altering precipitation extremes. This study aims to evaluate the observed hydrologic alteration caused by dam construction and simulate alteration due to expected climatic changes in a monsoon dominated mesoscale river basin in India. The paper by Neha Mittal, Ashok Mishra, Rajendra Singh, Ajay Gajanan Bhave and Michael van der Valk is now finally available to free.
