Introduction: A Harmonized Approach Towards Water Management in South Asia

Transboundary rivers are vital sources of freshwater globally, yet managing these shared waters poses significant challenges, including geopolitical tensions, unilateral water infrastructure development, and rising water demands. South Asia exemplifies these issues, with transboundary river treaties predominantly relying on quantitative/volumetric water-sharing frameworks for basin management and conflict resolution. This study critically examines key treaties, specifically the Indus Waters Treaty (IWT) between India and Pakistan and the Ganga Water Treaty (GWT) between India and Bangladesh, highlighting their strengths, limitations, and post-treaty complexities through a quantitative water-sharing lens. The analysis shows that a narrow focus on ‘partitioning of river/flow’ (quantitative water-sharing) within these treaties frequently fails to address critical factors such as dry-season flow variability, climate-induced risks, ecological requirements, benefit-sharing opportunities and escalating water demands. These gaps contribute to mistrust, geopolitical tensions, and treaty unsustainability despite their relative success. The study underscores the need for a more comprehensive framework that integrates quantitative allocation with qualitative principles, including equitable and no-harm approaches to water-sharing and benefit-sharing. Lessons from the IWT and GWT offer valuable guidance for future negotiations on the Tista/Teesta River between India and Bangladesh, emphasizing cooperative, adaptive and resilient strategies for sustainably managing South Asia's critical transboundary water resources.

Rapid increases in demand for food and energy as a result of population growth and economic development is placing ever increasing demands on limited water resources in South Asia, and climate change is expected further complicate water resource management. In spite of important reductions in poverty levels in recent decades the region is still home to a very large number of poor whose quality of life is directly affected by the availability and quality of water and water services. A significant fraction of the water resources of the region and a significant fraction of the poor are associated with major Himalayan transboundary rivers, and given growing water demand it is likely that the already significant sensitivity around water cooperation amongst co-riparians will increase. Understanding the risks and opportunities for transboundary cooperation in the river systems in South Asia is thus important for guiding sustainable transboundary basin management in the region. This study refines a novel method for a rapid assessment of these cooperation risks and opportunities and applies it to the Brahmaputra, Ganges and Indus river basins to test its utility. The method employs a fuzzy synthetic evaluation technique that combines fuzzy logic and an analytical hierarchy process to assess cooperation risk and opportunity in terms of a Risk-Opportunity Index (ROI). The ROI is a function of four composite development variables and three hegemony variables that indicate the various pressures on the basin water resource and the different control strategies riparians could adopt given existing power asymmetries. In the absence of a clear rationale for differential weighting, equal weights were assigned to all seven variables for this application. A “defuzzification” scoring method is used to define compromising, risk-averse and risk-taking variants of ROI for riparian pairs within each basin. Overall, the results for the compromising ROI suggest that the opportunities for bilateral cooperation are highest (and risks the lowest) in the Brahmaputra Basin and the opportunities are lowest (and the risks highest) in the Indus Basin. This overall assessment is consistent with current common perception. Within the basins the compromising ROI values suggest a few instances of high risk and/or low opportunity, as well as an approximately equal number of instances of medium risk/opportunity and low risk/high opportunity. The study demonstrates that the fuzzy synthetic evaluation technique has utility for rapidly identifying potential opportunities for riparian cooperation in transboundary basins, in order to guide dialogue processes and more detailed analyzes. The study also however, reveals some aspects of the method where further refinement would likely yield more reliable assessments of cooperation risks and opportunities. Specifically, further refinements could consider the relative geographic position of co-riparians within a basin, and the relative resource access of different riparians. The method only considers bilateral riparian interactions and not more complex multi-lateral interactions. The results of study may contribute to various ongoing regional and basin dialogues on water cooperation in South Asia.

Public management in South Asia has been influenced by the colonial past which has resulted in the domination of administrative systems by the bureaucrats. Bureaucracies remained firmly entrenched as powerful groups and performed both administrative and political functions. India, Pakistan, Bangladesh, Nepal and Sri Lanka represent cases with similar backgrounds which opted for different political and economic systems after achieving independence. Consequently, a number of issues have emerged in public management in South Asia. These include debureaucratization of the policy process, complex relationship between specialists and generalists, integration of administrative structures, reconciliation of merit and equity, choice between professional and political patronage, revitalization of management, bridging the ever widening gap between the citizens and administrators, and the establishment of a sound ethical base of administration. The success of South Asian governments in dealing with these issues will determine, to a considerable extent, the dimensions and directions of change. While some of the issues will have to be addressed in the natural course of development, others will require a substantial degree of commitment from the governments as well as the societies.

Increasing threats related to climate change, water scarcity, and impacts of water diversion have the potential to trigger regional instability in various areas around the globe. This phenomenon is most evident in area surrounding the Brahmaputra River, an international watercourse flowing through China (Tibet), India, and Bangladesh. Contrary to other transboundary river basins in South Asia, the Brahmaputra seem so far to have been much under-examined, especially considering the complex geopolitics involved and potential threats to regional stability. The present chapter aims to review transboundary water management in South Asia with a detailed zoom on the case of the Brahmaputra river basin. This chapter analyses the social and environmental impacts of large-scale hydropower projects on downstream ecosystems and river-dependent populations. It also identifies relevant approaches to sustainable water management and explores major hindrances to effective cross-border cooperation between the countries involved. We aim to ask whether and how can water become a source of international cooperation and shared prosperity rather than a source of conflict.

Climate change is a critical factor affecting transboundary water management in South Asia, requiring robust agreements like the Koshi Agreement between India and Nepal. Signed in 1954 and amended in 1966, it serves as an initial model for regulating shared water resources. The agreement promotes equitable sharing of the Koshi River basin’s water, flood control measures and disaster risk management. Key provisions include forming the Koshi River Commission, frequent official meetings and sharing data to confirm balanced usage and mutual cooperation. It addresses the vulnerability of Koshi basin communities to floods and landslides through early warning systems, infrastructure and community preparedness interventions. The Koshi agreement has strengthened climate resilience by integrating renewable energy and hydropower projects, nurturing sustainable development and economic growth. These projects have diversified energy portfolios while maximizing disaster preparedness and minimizing impacts. Achievements include improved water quality and flood control with challenges such as sedimentation and equitable benefit sharing. The agreement highlights the potential of adaptive management and innovative frameworks for sustainable water resource management. Future research should prioritize developing institutional arrangements, engaging stakeholders effectively and incorporating climate change considerations to enhance regional cooperation and resilience.

Managing water in an integrated and sustainable manner is currently challenging water resource managers throughout the world. It requires professionals from many disciplines working together with impacted stakeholders in crafting a strategy that is economically efficient, ecologically sound, and acceptable to all who are impacted by how this resource is managed over space and time. We at universities are continually thinking about how we can better prepare our students who elect to become our future water resources planners and managers. This paper identifies some of the issues and challenges facing educators in this field, and some possible ways of addressing them. The amount of water available and suitable for human use in the world is limited. Too many humans must live with less water than what they would like, and even need, to maintain their health let alone their overall welfare. Currently the world's water resource systems are not able to provide everyone reliable potable water at reasonable costs. Populations are increasing, as are per capita demands for water. The United Nations tells us about one person in six, on average, in this world has no access to safe drinking water, and about one in three lacks adequate sanitation. In many countries these percentages are substantially higher. One can assume that those without clean water to drink are sick. The World Health Organization (WHO) tells us more than 30 thousand children under the age of five die from either hunger or from water-borne and easily-preventable diseases. We use about 70 percent of our freshwater resources for agriculture. What we get for that varies considerably. The World Water Council believes that by 2020 we shall need 17 percent more water than is currently available if we are to feed everyone. Do all these grim statistics suggest a water crisis? Will there be a water crisis in the future? Much depends on how we manage our water and our watersheds (Rogers et al. 2006). And this in turn depends on our abilities at universities to provide the personnel with the training and capacity to manage this resource effectively. With perhaps a few exceptions, those of us who live in North America are not dying from lack of water or sanitation. We are fortunate. We seem to have enough water, although the recent droughts in the southeast and in the west suggests we may be increasingly challenged to meet our demands for water supplies, to keep our rivers flowing and clean and our aquatic ecosystems functioning as they should. We can manage all our natural resources better, and professionals know this, but deciding what is better and implementing measures to be better involves more than just professionals. Politicians representing the public, and increasingly the public itself, are participants in this decision-making process. They define what is “better” and when and how to act. And inevitably acting requires money. Acting in ways to prevent crises is not always easy to do. There are always more pressing matters that get people's attention – and their money – until of course there really is a water crisis. This has prompted the well-known concept called the hydro-illogical cycle illustrating the lack of interest in planning for floods during periods of drought, or in planning for droughts when experiencing a flood. Many of the issues facing water and environmental resource managers today generally stem from the following factors: changing priorities of water and environmental management objectives over time – for example from economic efficiency to ecological health and diversity that require changes in past policies and even infrastructure, the way our institutions work, the need for multiple disciplinary inputs and public participation, uncertainties regarding future demands, supplies, and pollutant types and loads, and a lack of adequate understanding of many natural and social processes affecting, and affected by, the management of water and environmental resources. Managers and planners are challenged to develop plans and policies for serving often conflicting multiple purposes and satisfying multiple objectives expressed by multiple stakeholders representing multiple interests and backgrounds, all lacking perfect knowledge of what economic, physical, chemical, biological, ecological and social impacts will result from what ever decisions they make. We all could benefit from better science, better management tools, better training of professionals in all the applicable disciplines, and political institutions that can provide the expertise and leadership that will result in more timely, integrated, and sustainable water resources and environmental management plans and policies. The remainder of this paper outlines some current issues related to the training of individuals who wish to accept the challenges just described and contribute to improving how we manage our water and environmental resources. Recent decades have witnessed a shift in emphasis by U.S. agencies providing funds for research and training of graduates interested in environmental and water resources management. The emphasis has been on addressing scientific uncertainties and less toward planning and management issues. This runs counter to those who claim there is a need for improved environmental and water resource management. One result of this shift away from research in planning and managerial issues has been the decline of academic programs in water management and planning. Ironically, weather- and climate-related research programs, as well as large-scale observation initiatives promoted by many in the hydrologic, ecological, environmental engineering and other communities, increasingly cite benefits for water resources, environmental, and ecological management as central to their programmatic justification. Having more scientific information and the understanding that comes from it does not automatically mean we know how best to use it. There are many scientific, technical, political, practical, and regulatory challenges to integrating advances in hydrologic science into policies for managing environmental and water resources. There may be an unrealized potential, for instance, for using improvements in hydrologic forecasting based on new data sources and methods, such as embedded environmental sensors and data assimilation techniques. As science teaches us more about the processes taking place at the interface of hydrology and climate, and as the hydrologic, water quality, and associated ecological implications of land cover change become better understood, ways are needed to incorporate this knowledge into management plans and policies. Research is needed to figure out how best to do that, and trained professional planners and managers are needed to make it happen. At various universities, debates are taking place over a variety of issues, some of which are listed below. Issue #1: Educational policy – should universities turn out more well-trained engineering professionals and scientists, or more broadly trained generalists? Many will argue that there is an overarching need for people who know there is a world beyond where they live and work and can appreciate how history and culture affects current events. There is a need for individuals who can evaluate, think, and speak and write effectively at technical and non-technical levels. In my opinion, such skills should be obtained at the undergraduate level. One way to get this background is to obtain a liberal arts education (including study in a foreign country). Expertise in specific technical disciplines can be obtained at the master's level. After all, medicine, law, and business are graduate subjects. Why not in this multidisciplinary water resource field as well? Obviously for those desiring engineering or the sciences some basic introductory courses would be expected at the undergraduate level, just as pre-med courses are expected for admission to most medical schools. This is not to say we cannot train students to become competent technical professionals with engineering, economic, ecological, or natural resource degrees, for example, at the undergraduate level, but doing that eliminates the time needed for students to obtain the other skills that all should have who expect to become tomorrow's leaders in whatever they do. Yet in much of the world, attending universities costs money, especially at private universities and colleges. This means we need fellowships and training grants to attract the best and brightest students we can to our water resources profession. Issue #2: Course curricula – do they need changing? Many universities need to take a serious look at their curricula more often than they do. It seems much easier to change course contents than the overall plan. Most educators support exposing students to interdisciplinary projects at both graduate and undergraduate levels, so that students learn to participate productively in such projects and recognize the approaches and issues of fields other than their own. Engineers, economists, and ecologists especially need to appreciate each other's approaches to problem solving. Being exposed to case studies, including failed projects and those that get students out in the field is also beneficial. This gives them an appreciation of multidisciplinary team-building and dealing with multiple conflicting goals such as drought mitigation, flood management, flash flood prediction, water supply, transportation, emergency management, agriculture, and ecosystem stewardship – and conflicting opinions about how to achieve them. Issue #3: Continuing education: How can it best be provided to all professionals? Some have suggested that whatever the technical information students learn, it will be obsolete by the time they get their first job. The rate of increase in knowledge and changes in technology seem to be increasing over time. The half-life of the technical information we teach our students is decreasing. On-the-job training and continuing education throughout one's professional career is an absolute necessity. How can universities best meet this need? Some governmental agencies concerned with environmental and water resources management have programs for continuing education. However, a high turnover rate often makes this uneconomic. Professors themselves need continuing education as well. Their research provides some of this, but they also can learn from their consulting and what they do on their sabbatical leaves. All professionals should be provided such opportunities, not just academics. Issue #4: Funding. Can the needed changes in education be accomplished in the absence of changes in funding “carrots and sticks”? Difficulties in supporting students studying water and environmental resources management have led to the relative lack of students studying these subjects. University deans look for where the money is when they analyze continuing and new directions for their academic departments. The availability of fellowships, traineeships, and research grants are noticed. Industry can also provide support, and in many disciplines they do, but in the water and environmental resources arena the private sector has not been a major player. Managing water and environmental resources is primarily a public responsibility. Nevertheless industry has provided some support, for example to the American Water Works Association Research Foundation which promotes research and technology transfer. Coop programs, internships, and traineeships that expose students to the real world may be a partial solution. The USDA-CSREES coop funding program is an example for agricultural water management. The U.S. Army Corps of Engineers master's degree program in planning is another example. Employers working in the water management area often report difficulties in finding employees with the appropriate backgrounds. Because of the decrease in funding of research and training grants in the water planning and management area, few young graduate students are finding their way into the field. This leads to fewer students being trained in the areas of most interest to these employers. The report Freshwater Ecosystems: Revitalizing Educational Programs in Limnology (National Research Council 1996) included a chapter on linking education and water resource management. Water is viewed as a public good, and thus those who manage it are often associated with government agencies. At a recent meeting of the National Research Council (Logan 2006), several government agencies stated their need for articulate young people prepared for working in interdisciplinary and multi-disciplinary teams, which is the nature of modern water management, viewing problems in a broad systems context – water management decisions made upstream “reverberate” downstream influencing eco-systems, fisheries, and the coastal zone in general, linking societal goals and objectives with performance measures and conceptual eco-logical models, adaptability in general and adaptive manage-ment in particular, quantifying and dealing with risk and uncertainty, and conflict management and resolution in a stakeholder-driven participatory political process. One can think of other skills needed to address some of our current and future management challenges. For example, how can managers most effectively design, manage and operate infrastructure in the face of non-stationarity in water supply and demand; identify and provide environmental flows in already over-allocated systems, especially in times of drought, and environmental effects of reservoir operation and dam removal; alter reservoir regulation in the face of changing uses and priorities, environmental and ecological uncertainties and needs, and possibly the removal of past engineering infrastructure such as dams and canals; predict and then respond to hydrologic responses to precipitation, surface water generation and transport, environmental stresses on aquatic ecosystems, the relationships between landscape changes, sediment fluxes, and subsurface transport, as well as mapping ground water recharge and discharge vulnerability; respond to the environmental, economic, health and social impacts caused by floods, droughts, sedimentation, and contamination including from pharmaceuticals and other household chemicals and products; provide an early warning for flooding, droughts, habitat degradation, and health hazards, increase the efficiency of water use, especially in the agricultural sector; address questions whose answers require knowledge of the quantitative relationships among various physical, chemical, biological, and social process occurring at disparate spatial or temporal scales. For example, how can we scale up to larger area forecasts from knowledge of smaller habitat patch scale ones? How can we estimate regional aquatic ecosystem processes over entire river basins often based on small plot experiments and observations? deal with deforestation, suburbanization, road construction, agriculture, and other human land-use activities that impact economies and ecosystems (changes in land cover, climate, and land use affect water quantity and quality regimes which impact ecosystem health and other uses of water such as for drinking, irrigation, industry and recreation); manage chemical and biological components of the hydrological cycle under changing land uses and habitats, and control invasive species … This list could continue. Suffice to say there are many subjects a competent water resource manager should be familiar with, at least to the extent that the issues are appreciated and that effective communication can take place between the manager and experts or specialists when appropriate. Today's planning and management environment involves public participation, not just at the final stages of planning, but throughout the process, including decision making. Tools are being developed to help all stakeholders gain a “shared vision” of how their system works, and the physical, economic, environmental, ecological and sometimes the social impacts of various plans and management policies. Such public participation does not make the planning and management processes any easier, or more efficient, or cheaper. In fact often the opposite happens. But the end result has a far better chance of being robust to multiple interests and thus more sustainable in the long run (ASCE 1998). Future water resources managers need to know how to facilitate such participation. Water resources professors cannot rest on their laurels. Planning and management issues continue to evolve as do their demands on this profession. Students today will be faced with problems and technology we can only speculate about today. But they have to be prepared to effectively address those issues and use that technology. It's the job of those of us involved in water resources planning and management programs at universities to ensure our graduates have that capability. The increasing breadth, complexity, and rate of change of professional practice places a greater emphasis not only on continuing education but also on what a basic professional education must deliver at the undergraduate as well as graduate levels. The body of knowledge necessary to effectively manage water resources is beyond the scope of the traditional bachelor's degree, even when coupled with early-career experience. Education must meld technical excellence with the ability to lead, influence, and integrate a diverse number of disciplines and stakeholders – all required to meet societal goals in some ‘best’ and most sustainable way. Ideally, graduates from university programs in water resources planning and management should be knowledgeable in their particular discipline, as well as conversant with other applicable disciplines. An engineer, for example, should not only understand how to use the theories, principles, and/or fundamentals of mathematics, physics, chemistry, engineering economics, biology, and probability and statistics underlying engineering but also be exposed to political processes, systems analysis and computer modeling, laws and regulations, history, sociology, and ethics. Most importantly, they should know how to work in interdisciplinary teams and effectively and clearly communicate orally and in writing. They must be optimistic in the face of challenges and setbacks they will surely face, and be committed to ethical behavior, both personally and professionally. After graduation they must remain curious and willing to continue learning fresh approaches, develop and use new technology or innovative applications of existing technology, and take on new endeavors that require research and ingenuity. Managing our water resources, including our ecosystems in our natural and built environments, involves both technical and administrative expertise. It involves both the “hard” as well as the “soft” sciences. In the hard sciences, the laws of physics, biology, chemistry, and mathematics are well established. The same cannot be said of the soft social and political sciences. Thus the “hard” sciences are easy. The “soft” sciences are hard. Clearly, however, we need more people competent in both to address many of the issues water resource managers are facing today. Daniel P. Loucks is a professor in the School of Civil and Environmental Engineering at Cornell University in Ithaca, NY, USA, (www.cornell.edu) where he teaches and directs research in the development and application of economics, ecology and systems analysis methods for estimating the impacts of alternative policies aimed at solving environmental and regional water resources problems. He has authored articles and book chapters in these subject areas and has been involved in various development and environmental restoration projects throughout the world.

South Asia, with its burgeoning population density and poverty on the one hand, and rapid urbanization and industrialization on the other, seems to be facing an impending water crisis. This crisis is not due to water shortage, but due to conflicts over water use at various levels. The governments in the region have neglected the knowledge base needed to research water systems management and deal with these conflicts. The paper stresses that only a transdisciplinary approach, including the engineering and medical sciences, along with social, political, and economic expertise, can help in poverty alleviation and development. Eventually, the paper traces the knowledge gaps in water systems management in South Asia and sets forth a research agenda based on the emergent paradigm of integrated water resources management.

Smart water management, driven by the integration of photovoltaic (PV)- powered pumps and the Internet of Things (IoT), represents a revolutionary approach to address the challenges of sustainable water resource management. This chapter explores the concept of "Smart Water Management: PV-Powered Pumps and IoT Integration," highlighting the transformative potential of combining solar energy with intelligent data-driven decision-making in water pumping systems. The chapter begins by tracing the evolution of water management practices, emphasizing the need for more sustainable and efficient approaches in the face of increasing water demands, population growth, and climate change. According to the United Nations World Water Development Report 2021, an estimated 2.2 billion people lack access to safely managed drinking water services, underscoring the urgency of sustainable water management solutions. It then focuses on the advantages of PV-powered pumps over conventional fossil fuel-based alternatives, including reduced carbon emissions, cost- effectiveness, and energy independence. Advancements in PV technology and its potential applications in smart water management are also discussed. The World Health Organization estimates that around 485,000 people die each year from diarrhea, primarily due to unsafe drinking water and poor sanitation, highlighting the need for improved water quality monitoring and management. The pivotal role of the Internet of Things in smart water management is explored, highlighting how IoT integrationelevates water pumping systems to new levels of intelligence and efficiency. Real- time data collection, remote monitoring, predictive maintenance, and adaptive control mechanisms empower stakeholders with valuable insights for optimizing water usage and ensuring system reliability. Efficient water distribution and consumption, critical elements of smart water management, are addressed through IoT-enabled sensors and data analytics. Case studies demonstrate successful implementations of IoT-driven smart water distribution projects across various sectors. The chapter also delves into how IoT- enabled water quality monitoring enhances safety and supports environmental conservation efforts. Smart water management's impact on resilience and disaster management is examined, showcasing its ability to facilitate rapid response and recovery during emergencies. A study by the International Energy Agency (IEA) indicates that the deployment of solar PV for water pumping applications has the potential to save around3.6 billion liters of diesel fuel and avoid nearly 10 million tonnes of CO2emissions annually by 2030.Furthermore, the integration of PV-powered pumps with urban infrastructure and smart grids is explored to optimize water resources and enhance sustainable urban water management. The United Nations projects that by 2050, 68% of the world's population will reside in urban areas, further exacerbating water challenges. Smart water management powered by PV and IoT technologies offers a scalable and efficient approach to address the growing water demands of urbanization. The chapter concludes by discussing the policy and governance aspects necessary for scaling up smart water management practices. Regulatory frameworks, incentives, and public-private partnerships play a crucial role in fostering widespread adoption of PV-powered pumps and IoT integration for sustainable water management. In summary, "Smart Water Management: PV-Powered Pumps and IoT Integration" holds the promise of transforming water management practices. Leveraging solar energy and intelligent data-driven decision-making, smart water management enhances efficiency, conserves water resources, and mitigates environmental impact. Embracing this paradigm shift is vital in ensuring water security and resilience in the face of global water challenges and environmental concerns.

Energy management in South Asia

Municipal solid waste (MSW) management in South Asia represents one of the most pressing urban governance challenges, shaped by rapid urbanization, institutional fragmentation, and weak integration of circular economy principles. This paper undertakes a decade-long systematic and bibliometric review (2015–2025) of 592 peer-reviewed studies retrieved from Scopus applying PRISMA guidelines. The bibliometric analysis demonstrates a steep rise in scholarly output, from fewer than 30 papers in 2015 to over 130 in 2024, with India and Bangladesh accounting for the majority of contributions, while smaller states such as Bhutan, Maldives, and Afghanistan remain underrepresented. Research is concentrated in engineering and environmental sciences, with keyword clusters shifting from traditional waste disposal and landfilling toward circular economy, recycling, and governance integration. Across the systematic evidence base, India, Bangladesh, and Pakistan generate over 80% of South Asia’s MSW yet recycle less than 25%, highlighting systemic deficiencies in policy coherence, financing, and informal sector recognition. This study contributes uniquely by benchmarking governance frameworks across eight South Asian countries, aligning technological and policy innovations with sustainability pathways, and advancing a regional roadmap for inclusive, circular, and resilient MSW governance.

Despite the fact that sustainable agricultural technologies and practices have been developed and introduced to farmers in both developed and developing countries, there are concerns about low levels of adoption. Empirical evidence of the past 40 years shows that adoption of new practices can be hindered by a wide range of factors, from financial to attitudinal, from personal to social, from agronomic to regulatory. Conclusions that can be generalised across different contexts could help in moving the institutional and policy environment in a direction that strengthens the move towards a more sustainable food production. This is particularly important regarding hotspots of environmental pollution, for example, the release of reactive nitrogen compounds in South Asia. This paper followed the PRISMA protocol and systematically reviewed the adoption literature in South Asia to identify factors that affect farmers' decisions to adopt sustainable agricultural technologies and practices. We found that education, extension and training, soil quality, irrigation, income and credit are significant drivers of farmers' adoption decisions. Consequently, efforts to promote the adoption of sustainable nitrogen management technologies will have to be tailored to consider these factors. We conclude that the variables that explain adoption in the studies reviewed could provide a foundation invaluable to research and policies that facilitate the adoption of sustainable nitrogen management technologies and practices in South Asia.

This chapter explores the conceptual terrain at the interface of physical–technical science and social science approaches to water management, looking for boundary concepts that allow us to think the different dimensions of water management simultaneously rather than separately. It seeks to find ways to combine a socio-political perspective of water management policy, institutions, and organizations with a perspective on the politics of technology, infrastructure, and landscapes. It gives an overview of the different ways in which such conceptual hybridization has been attempted. More specifically, it illustrates how this has been elaborated in the South Asian context, particularly in the research conducted under the ‘Matching Technology and Institutions’ project of which this volume is the collective output. It reflects on the experience of the kind of interdisciplinary research that formed the basis of this volume and stresses the importance of this approach for future academic and policy-related research.

This paper reviews the experience with gender mainstreaming in the water sector in South Asia. It analyzes the reasons for the limited impact of these efforts. These are located in the limited understanding and consequent operationalization of the concept of gender itself. Rather than equating the word gender with women, it needs to be understood to refer to the social and power differences between men and women and the differences within women. Gender needs to be approached in policy and practice through a lens of intersectionality. Reserving seats for women in local patriarchal structures of decision making does little to alter the status quo; securing women's participation in water management activities without altering power relations between water users and service providers only creates additional work burdens for them. The changing nature of water resources education in the region means that water problems shall be seen differently in the future and that there will be more women in this sector. There is a need to develop curricula based on ways of theorizing about gender and water in different agro‐ecological and institutional settings embedded in the unique context of South Asia.
