The Barind region, a water-stressed area in northwest Bangladesh, had an underdeveloped agricultural economy and high levels of poverty until two projects revitalized the area with enhanced groundwater irrigation. The Barind Integrated Area Development Project in 1985 and Barind Multipurpose Development Authority (BMDA) in 1992 used new water extraction technology and innovative management practices such as deep tubewells (DTWs) fitted with smart card-operated electric pumps to develop drought-resilient irrigation. Both projects have helped the Barind region reduce poverty and achieve self-sufficiency in rice. However, there are concerns about declining groundwater levels in the Barind and nearby regions, resulting in a temporary halt in DTW expansion. Preliminary evidence presented in this case study suggests farmers served by shallow tubewells (STWs) may be losing access to groundwater in some parts of the Barind region, which can have significant development implications because these tubewells remain the predominant source of irrigation. This evidence provides grounds to question whether an irrigation model reliant on DTWs is sustainable and equitable in the long term. Further research is needed to better establish groundwater conditions and understand the risk to STW users to inform future policy on DTW-driven agricultural development.

The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members as well as 37 Partners to publish the United Nations World Water Development Report (WWDR) series. Under the theme Water for Sustainable Development, the WWDR 2015 has been prepared as a contribution from UN-Water to the discussions surrounding the post-2015 framework for global sustainable development. Highlighting water's unique and often complex role in achieving various sustainable development objectives, the WWDR 2015 is addressed to policy- and decision-makers inside and outside the water community, as well as to anyone with an interest in freshwater and its many life-giving benefits. The report sets an aspirational yet achievable vision for the future of water towards 2050 by describing how water supports healthy and prosperous human communities, maintains well functioning ecosystems and ecological services, and provides a cornerstone for short and long-term economic development. It provides an overview of the challenges, issues and trends in terms of water resources, their use and water-related services like water supply and sanitation. The report also offers, in a rigorous yet accessible manner, guidance about how to address these challenges and to seize the opportunities that sound water management provides in order to achieve and maintain economic, social and environmental sustainability.

Problems with water security are a critical part of the overall experience of poverty that so many face. This paper outlines a pro-poor framework for action, linking poverty to water security and introducing interrelated issues of governance, water quality, access, livelihood opportunities, capacity building and empowerment, water related disaster prevention and management, and sustainable water resources and ecosystem management.

This book provides a comprehensive analysis of the benefits and challenges of intensifying groundwater irrigation in Sub-Saharan Africa (SSA) for improving smallholder agrarian livelihoods. Only about 3% of the groundwater resources of Sub-Saharan Africa are used for irrigated agriculture despite the subcontinent’s relative abundance of groundwater. The majority of the region’s smallholders are highly dependent on seasonal dryland cropping, making them extremely vulnerable to uncertain weather patterns and droughts. Improved irrigation capabilities through sustainable groundwater development could unleash smallholder farming and make it a major driver of economic growth, poverty reduction, climate resilience, and improved food security. So, why is groundwater so underused? Tapping into groundwater requires a major shift in farming practices and it has its own challenges and requirements – smallholder access to land and finance for irrigation infrastructure and equipment, gendered and equitable adoption options. This whole list is framed in terms of what the smallholder farmers need. Hence, this should also be put in this context, supply chains, energy access, resource availability, and institutional support. The chapters in this book present a picture that is not only heterogeneous across the region, but also hold some common denominators. They serve to enrich the discourse and help better understand the barriers along the pathways toward the sustainable and transformative adoption of groundwater irrigation. The scientific information provided herein would be of interest to researchers, practitioners, decision makers and planners with interest in the region. This book was originally published as a Special Issue of Water International journal.

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.

This volume advances the scientific understanding, development, and application of geospatial technologies related to groundwater resource management, mapping, monitoring, and modelling using up-to-date remote sensing and GIS techniques. The book further provides a critical analysis of the debates and discourses surrounding groundwater resources and society, illustrates the relationship between groundwater resources and precision agriculture for societal development, and describes novel, region-specific management strategies and techniques for sustainability with case studies. The book is organized into three parts: (I) Groundwater resources and societal development; (II) Groundwater availability, quality and pollution; and (III) Sustainable groundwater resources management. Each section begins with a short introduction that includes an overview of the papers in that section. Individual chapters focus on the core themes of research and knowledge along with some topics that have received lesser attention. The book will be of interest to water resource planners and decision-makers, academic researchers, policy makers, NGOs, and academic researchers and students in Geography, Geophysics, Hydrology, Remote Sensing & GIS, Agriculture, Soil Science, and Agronomy.

This report draws on a survey and case study evidence from 28 watershed management groups in Haryana to argue that participatory watershed management projects need not necessarily safeguard the interests of poorer rural households.

This text is written by a number of authors from different countries and disciplines, affording the reader an invaluable and unbiased perspective on the subject of intensive groundwater development. Based on information gathered from the experience of many countries over the last decades, the text aims to present a clear discussion on the conventional hydrogeological aspects of intensive groundwater use, along with the ecological, legal, institutional, economic and social challenges. Divided into two main sections, the first group of authors put forward the positive and negative aspects of intensive groundwater use, whilst a second group provide an overview of the situation specific countries face as a consequence of this phenomenon. Fully revised and up-to-date, Groundwater Intensive Use makes a significant number of discoveries in a subject area that is topical in today's climate.
