Download or read book Groundwater written by Raya Marina Stephan and published by Taylor & Francis. This book was released on 2023-02-21 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is invisible, but its impact is visible everywhere. Everything around us relies on groundwater, our drinking water and sanitation, our food supply and our natural environment. Yet because it is invisible, information, management and governance of groundwater is often poor and inadequate. This book contributes to UN Water Groundwater year (2022), and to the effort of “making the invisible, visible”. Through worldwide case studies ranging from the Americas (California, Brazil), to Asia (India, Iran, Lao PDR, Nepal), Africa (Malawi, Tanzania, South Africa) and the MENA region (Lebanon, Morocco, Yemen), including cases of transboundary aquifers, the chapters in this edited volume reflect important recent advances in interdisciplinary knowledge on the governance, management, practice and science-policy interfaces of groundwater. An insightful resource for researchers and planners in the field of environmental policies, water laws, climate change and groundwater governance, this book comes with a new Introduction. The other chapters were originally published in Water International.

Download or read book Water Loss Assessment in Distribution Networks written by Taha M. Al-Washali and published by CRC Press. This book was released on 2021-06-07 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for rethinking the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent supply networks. Water loss assessment methods were originally developed in continuous supply systems, and their application in intermittently operated networks (in developing countries) is hindered by the widespread use of household water tanks and unauthorised consumption. This study provides an extensive review of existing methods and (software) tools for water loss assessment. In addition, several new methods were developed, which offer improved water loss assessment in intermittent supply. As the volume of water loss varies monthly and annually according to the amount of supplied water, this study proposes procedures to normalise the volume of water loss in order to enable water utilities to monitor and benchmark their performance on water loss management. The study also developed a novel method of estimating apparent losses using routine data of WWTP inflows, enabling future real-time monitoring of losses in networks. Different methods have also been suggested to estimate the unauthorised consumption in networks. This study found that minimum night flow analysis can still be applied in intermittent supply if an area of the network is supplied for several days. Furthermore, this study concluded that water meter performance is enhanced in intermittent supply conditions. However, continuous supply in the presence of float-valves significantly reduces the accuracy of water meters. Finally, this study provides guidance and highlights several knowledge gaps in order to improve the accuracy of water loss assessment in intermittent supply. Accurate assessment of water loss is a prerequisite for reliable leakage modelling and minimisation as well as planning for, and monitoring of water loss management in distribution networks.

Available in PDF, EPUB and Kindle. Book excerpt: Information-based decision-making during drought, often brings out some of the excellent practices that are prevalent in society / individuals. This book is designed to provide information on the drought process, meteorological, hydrological, agriculture, socio-economic aspects and available technologies such as satellite remote sensing data analysis and Geographical Information system for assessment. Assessment procedures utilising the various parameters of importance from various sources for micro level management that would enhance the effectiveness of management practice are dealt in detail. Resource availability and affected group determine the relief assistance for the present event and information that would help them in their realisation and preparedness for the forthcoming years by select countries is highlighted. This would help in the formulation of schemes for event mitigation and area development plans. The readers would gain complete knowledge on drought. This book is expected to act as a guide in preparing people as effective natural resource utilizationist under drought situations.

This book was released on 2022-08-18 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project “Strengthening Food Security Information and Early Warning System,” was a two-year (1 February 2019 – 31 January 2021), EUR 5.9 million project funded by the European Union to scale up the geographic coverage of Yemen’s Food Security Information System. The overall objective of the project was to increase systemic resilience to food crisis and climate change as well as improve food security and nutrition governance for decision-making at the national- and governorate-levels. The project is the latest phase in a series of EU-funded investments since in food security information systems in Yemen, with this project aiming to expand the geographic and technical coverage of previous phases. With these investments expected to continue in the future, the evaluation has aimed to provide accountability to project partners as well as the provision of evidence-based analyses and usable recommendations that feed into programming, policy and decision-making processes.

Download or read book Evaluation of the project Water for Peace in Yemen Strengthening the role of women in water conflict resolution written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2022-07-05 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project ‘Water for Peace in Yemen: Strengthening the role of women in water conflict resolution’ was funded by the United Nations Secretary-General's Peacebuilding Fund (PBF). The project was implemented jointly by the Food and Agriculture Organization of the United Nations (FAO), the International Organization for Migration (IOM), the Hadramout Ministry of Water and Environment, and the Women Water Users Groups (WWUG). The ‘Water for Peace in Yemen’ project aimed at contributing to the mitigation of water-based conflicts that have affected agriculture, with the inclusion of women as conflict-resolution agents. Farming communities (men, women and youth) were engaged by the project to resolve local conflicts over upstream and downstream water allocation. Moreover, the project aimed to introduce drought-tolerant as well as salt-tolerant crops as a climate change mitigation measure in a cash-for-work (CFW) modality. The evaluation found that the project's main achievements were the institutionalization of this role through the water user associations (WUAs) and strengthening the role of women within their communities.

Download or read book Groundwater Pollution Aquifer Recharge and Vulnerability written by N. S. Robins and published by Geological Society of London. This book was released on 1998 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary groundwater management issue in many countries today is pollution. This may derive from a point source, perhaps a leaking solvent store at a factory, or it may be diffuse, such as the threat posed by the use of agricultural fertilisers and pesticides. The key to understanding the transport of a pollutant from the ground surface or near surface into an aquifer is an understanding of recharge. In turn, this allows the vulnerability of aquifers to pollution to be classified and appropriate land zones to be defined. Land zonation of different classes of aquifer vulnerability is a valuable tool for management and planning. In this volume the recent developments within the interlinked areas of groundwater pollution, aquifer recharge and vulnerability are set against the current groundwater protection policies of the UK amd Republic Ireland.
