Abstract Cities have become important actors in international relations, and integral to security and environmental politics. We are living in an increasingly urban world, dominated by human settlements and activities. The central role now played by humans in shaping the planet has led us into an uncertain, unstable, and dangerous geological epoch – the Anthropocene – that poses great and additional challenges to security. Local and global spheres are connected as never before, generating ‘glocal’ issues in which water plays a central role. Water is the element that interconnects the complex web of food, energy, climate, economic growth, and human security. In a rapidly urbanising world, cities influence the hydrological cycle in major but uncertain ways, affecting water resources beyond their boundaries. There is no doubt that these issues are highly relevant to the discipline of International Relations (IR). However, IR scholars have been slow to engage with them, and most academic studies of cities and water security still emanate from the natural sciences. This article examines the ways in which cities in the Anthropocene challenge water security, and why IR needs to reinvent itself if it wants to sustain its contribution to global security.

Africa faces difficult water/sanitation legacies in the form of high hydrological variability and a multiplicity of transboundary river basins alongside poor sanitation. These challenges impeded the continent’s economic growth. Balanced investments in water resource and sanitation infrastructure and institutions are needed to increase productive uses of water, to mitigate the effect of recurrent floods and droughts, and to achieve basic water security as a platform for Africa’s economic growth. Priority should be given to investments that (a) focus on growth, (b) reduce rural poverty, (c) build climate resilience and adaptation, and (d) foster cooperation in international river basins. Because most African countries have low stocks of hydraulic infrastructure, emphasizing investments in infrastructure is appropriate for them. However, institution building and reform, improvements in water/sanitation management and operations, and strengthening of water information systems must complement growth in infrastructure. Development of institutions should be advanced in parallel with infrastructure investment.

Water governance and management are important challenges for the River Indus Basin in Pakistan. Water governance refers to social, political and economic factors that influence water management. The water scarcity and water security are a major concern for the state to control its water resources. The study aims to give Sindh water policy by exploring the challenges to Indus Basin in managing water resources and to identify opportunities Indus Basin can look to improve water management. Interviews were conducted from water experts and analysts having 5 years’ experience or more in the water sector of Pakistan through a semi-structured self-developed questionnaire using purposive sampling technique and transcripts were analyzed using thematic content analysis. The findings show that increasing population, climatic change and rising demand of water are major challenges Indus is facing and Indus with time is getting water-scarce therefore need strong institutions, civil society and legislatures to ensure equitable distribution of water and maintain the ecosystem. The study emphasizes that water governance and management are necessary for sustainable use of water. Pakistan, the water stress country needs to address ‘governance’ at a wider scale to solve problems in the Indus Basin for the livelihood of people. The research will benefit the state, water experts, institutions as well as civil society to promote efficient use of water in Indus Basin.

<p>The assessment of climate change and land use modifications effects on hydrological cycle is challenging. We propose an approach based on Budyko theory to investigate the relative importance of natural and anthropogenic drivers on water resources availability. As an example of application, the proposed approach is implemented in the island of Sardinia (Italy), which is affected by important processes of both climate and land use modifications. In details, the proposed methodology assumes the Fu’s equation to describe the mechanisms of water partitioning at regional scale and uses the probability distributions of annual runoff (Q) in a closed form. The latter is parametrized by considering simple long-term climatic info (namely first orders statistics of annual rainfall and potential evapotranspiration) and land use properties of basins.</p><p>In order to investigate the possible near future water availability of Sardinia, several climate and land use scenarios have been considered, referring to 2006-2050 and 2051-2100 periods. Climate scenarios have been generated considering fourteen bias corrected outputs of climatic models from EUROCORDEX’s project (RCP 8.5), while three land use scenarios have been created following the last century tendencies.</p><p>Results show that the distribution of annual runoff in Sardinia could be significantly affected by both climate and land use change. The near future distribution of Q generally displayed a decrease in mean and variance compared to the baseline.   </p><p>The reduction of  Q is more critical moving from 2006-2050 to 2051-2100 period, according with climatic trends, namely due to the reduction of annual rainfall and the increase of potential evapotranspiration. The effect of LU change on Q distribution is weaker than the climatic one, but not negligible.</p>

Procedural extensions of SQL have been in existence for many decades now. However, little is known about their magnitude of usage and their complexity in real-world workloads. Procedural code executing in a RDBMS is known to have inefficiencies and limitations; as a result there have been several efforts to address this problem. However, the lack of understanding of their use in real workloads makes it challenging to (a) motivate new work in this area, (b) identify research challenges and opportunities, and (c) demonstrate impact of novel work. We aim to address these challenges with our work. In this paper, we present the results of our in-depth analysis of thousands of stored procedures, user-defined functions and triggers taken from several real workloads. We introduce SQL-ProcBench , a benchmark for procedural workloads in RDBMSs. SQL-ProcBench has been created using the insights derived from our analysis, and thus represents real workloads. Using SQL-ProcBench, we present an experimental evaluation on several database engines to understand and identify research challenges and opportunities. We emphasize the need to work on these interesting and relevant problems, and encourage researchers to contribute to this area.

Despite the ‘immense’ water resources available, Nepal has not been able to transform this abundance of water resources into desired economic growth and societal welfare. This paper attempts to analyze the reasons for such incessant challenges that loom over water resources development in Nepal. This paper finds that it is not the resource that limits the development of water resources, but the approaches and wishes that are framed on the foundation of persistent myths. Analyzing those myths, this paper highlights the realities in water resources management of Nepal, and suggests that without dismantling the existing myths, the sustainable development of water resources seems limited.HYDRO Nepal JournalJournal of Water, Energy and Environment Issue: 23Year: 2018
